The present invention relates to a beam-column joint and a building structure including the same. Specifically, the present invention relates to a beam-column joint having a cap plate structure with a narrow portion and a building structure including the same.

Taiwan is located in an earthquake-prone area, and the damage caused by earthquakes is countless. In order to improve the stability and reliability of buildings and reduce or avoid casualties and property damage, earthquake resistance is often considered in the design of building structures. In addition, when subjected to excessive impact, stress may still cause certain damage to the building, so it is also necessary to consider how to guide the stress and concentrate the possible damage to the expected location, thereby reducing or avoiding the damage to important structures such as the main trunk supporting the building or the main trunk junction such as the weld. Furthermore, when damage occurs, it is also hoped that technology can be developed to make the process of repairing or replacing damaged structural parts more convenient and rapid, thereby extending the life of the building, promoting the maintenance efficiency of the entire building, and reducing or avoiding further expansion of the scope of damage or affecting other structures in the building.

The cover plate structure may at least include a first cover plate extending along a first direction across the first break to face and cover the first wing plate, and the first cover plate may be fixedly connected to the first end block and the first extension block. The first cover plate may have a first narrow portion corresponding to the first break, and the width of the first narrow portion may be smaller than the width of other parts of the first cover plate except the first narrow portion.

The joint structure can extend along a first direction, and can have a web, and a first wing plate connected to the first side edge of the web, and the first wing plate can have a first break and be divided into a first end block and a first extension block. The cover plate structure can at least include a first cover plate extending along the first direction across the first break to face and cover the first wing plate, and the first cover plate can be fixedly connected to the first end block and the first extension block. The first cover plate can have a first narrow portion corresponding to the first break, and the width of the first narrow portion can be smaller than the width of other parts of the first cover plate except the first narrow portion.

Comparison with the efficacy of previous technologies

The beam-column joints and building structures including the same provided in the embodiments of the present invention can improve the earthquake resistance of the entire building, and can concentrate stress on the expected narrow part to reduce or avoid stress damage to other parts of the building structure. In addition, when damage occurs at the expected part of the beam-column joint, the beam-column joints and building structures including the same provided in the embodiments of the present invention can also more conveniently replace the damaged part of the beam-column joint while reducing or avoiding the movement of other structures to complete the repair of the entire beam-column joint and building structure. Therefore, the materials needed to maintain the entire building can be reduced, and the recovery of the building after the earthquake can be accelerated to extend the service life of the building, and reduce or avoid further damage to the building due to the damaged structure.

Various embodiments will be described below, and those with ordinary knowledge in the art should be able to easily understand the spirit and principles of the present invention by referring to the description with accompanying drawings. However, although some specific embodiments will be specifically described in the text, these embodiments are only exemplary and are not to be considered as limiting or exhaustive in all aspects. Therefore, for those with ordinary knowledge in the art, various changes and modifications of the present invention should be obvious and easily achievable without departing from the spirit and principles of the present invention.

Referring to FIG. 1 and FIG. 2 , according to one embodiment of the present invention, a building structure 10 having a replaceable beam-column joint AT is disclosed. As mentioned above, the building structure 10 may include a column structure CL extending along a vertical direction DT, and at least one beam-column joint AT having a joint structure 100 and a cover plate structure 200 connected to at least one side surface of the column structure CL, such as a first side surface S1. According to some embodiments, the column structure CL may be a column-type steel structure or an H-shaped steel structure, and the beam-column joint AT is a structure formed by welding or assembling steel plates, but the materials and types applicable to different embodiments of the present invention are not limited thereto. The joint structure 100 may extend along a first direction D1 intersecting the vertical direction DT, and may include a web 110 whose end in the first direction D1 may be fixedly connected to (e.g., locked or welded to) the column structure CL, and a first wing W1 extending from the first side surface S1 and connected to the first side edge E1 of the web 110 along the first direction D1. As described above, the first wing W1 may have a first fracture F1 and be divided into a first end section W12 relatively close to the first side surface S1 and a first extension section W14 relatively far from the first side surface S1.

Continuing with the above description, according to the present embodiment, the cover plate structure 200 can be matched with the joint structure 100. Specifically, the cover plate structure 200 can include at least a first cover plate 210 extending along the first direction D1 across the first break F1 and facing and covering the first wing plate W1. As mentioned above, the first cover plate 210 can be fixedly connected to (for example, locked to) the first end block W12 and the first extension block W14, so as to be suspended on the first break F1. The first cover plate 210 can have a first narrow portion 215 corresponding to the first break F1, and the width of the first narrow portion 215 is smaller than the width of other parts of the first cover plate 210 except the first narrow portion 215. In detail, the width of the first narrow portion 215 in a second direction D2 perpendicular to the first direction D1 and the vertical direction DT can be relatively reduced, so that the structure of the first cover plate 210 corresponding to the first narrow portion 215 is relatively weakened. Therefore, according to this embodiment, when there is an impact such as an earthquake, the stress pressure on the building structure 10 (such as the misalignment between beams) can be correspondingly directed to the first narrow portion 215 whose structural strength is weakened and below which is the first fracture F1, and may be correspondingly damaged (such as cracked or deformed). In this way, stress and pressure that may be caused to the column structure CL, the joint structure 100 of the beam-column joint AT, or the connection between the column structure CL and the joint structure 100 or other important structures can be transferred or absorbed, thereby reducing or avoiding damage to these structures caused by earthquakes or shocks.

As described above, according to the present embodiment, since the first cover plate 210 is not directly connected to the column structure CL, and the first narrow portion 215 that is more easily damaged is below the first fracture F1, the impact on the joint structure 100 is reduced or avoided, and the damage can be relatively guided and limited to the expected position other than the connection between the beam-column joint AT and the column structure CL. Therefore, according to some embodiments, depending on the impact size and damage, it may be possible to only disassemble the damaged first cover plate 210 from the first wing plate W1 accordingly to complete the replacement and repair of the building structure 10 and the beam-column joint AT after the impact. As described above, without replacing and/or repairing the joint structure 100, the convenience of maintaining the building structure 10 and the beam-column joint AT after impact can be improved, and the time and materials required for replacing and/or repairing the building structure 10 and the beam-column joint AT can be reduced.

Furthermore, according to some embodiments, in order to further enhance the above-mentioned effect, a similar configuration may be performed on the second side edge E2. Specifically, as shown in FIG. 1 and FIG. 2 , the first side edge E1 and the second side edge E2 may be opposite to each other in the vertical direction DT, and both extend along the first direction D1. As described above, the joint structure 100 may further include a second wing plate W2 extending from the first side surface S1 and connected to the web 110 and the second side edge E2 opposite to the first side edge E1. The second wing plate W2 also similarly has a second fracture F2 and is divided into a second end portion block W22 relatively close to the first side surface S1 and a second extension block W24 relatively far from the first side surface S1. In addition, the cover plate structure 200 may further include a second cover plate 220 extending along the first direction D1 across the second break F2 to face and cover the second wing plate W2. As described above, the second cover plate 220 may be fixedly connected to the second end block W22 and the second extension block W24, so as to be suspended on the second break F2. The second cover plate 220 may have a second narrow portion 225 corresponding to the second break F2, and the width of the second narrow portion 225 may be smaller than the width of other parts of the second cover plate 220 except the second narrow portion 225.

As described above, according to the present embodiment, by providing the second narrow portion 225, similar to the first narrow portion 215, stress and pressure are directed and concentrated on the second narrow portion 225, and damage (such as but not limited to cracking or deformation) may be generated on the second narrow portion 225 that is not supported by the second wing plate W2 and is narrowed and weakened. In addition, since damage to the joint structure 100 and the column structure CL is reduced or avoided, according to the present embodiment, if the second narrow portion 225 of the second cover plate 220 is damaged, the building structure 10 and the beam-column joint AT can be replaced and/or repaired more easily by disassembling and replacing the second cover plate 220 from the second wing plate W2. Therefore, it is possible to improve the convenience of maintaining the building structure 10 and the beam-column joint AT after an impact without replacing and/or repairing the joint structure 100, and reduce the time and materials required for replacing and/or repairing the building structure 10 and the beam-column joint AT.

Furthermore, according to some embodiments, in order to make the arrangement of the first cover plate 210 and the second cover plate 220 more stable, according to the building structure 10 and the beam-column joint AT of the present embodiment, the cover plate structure 200 may further include a first reinforcing plate R1, a pair of first intermediate clamps U10, and a pair of first base clamps U20 corresponding to the first cover plate 210, and further include a second reinforcing plate R2, a pair of second intermediate clamps U30, and a pair of second base clamps U40 corresponding to the second cover plate 220. As described above, according to this embodiment, the first reinforcing plate R1 can overlap and cover the first narrow portion 215 and be disposed on a surface of the first narrow portion 215 that faces away from the first wing plate W1, and the second reinforcing plate R2 can overlap and cover the second narrow portion 225 and be disposed on a surface of the second narrow portion 225 that faces away from the second wing plate W2. In addition, the pair of first intermediate clamping plates U10 can be disposed on both sides of the first narrow portion 215 parallel to the first direction D1, and the pair of first base clamping plates U20 can overlap and correspond to the pair of first intermediate clamping plates U10 and be disposed at the first break F1 parallel to the first direction D1. Similarly, the pair of second intermediate clamping plates U30 may be disposed on both sides of the second narrow portion 225 parallel to the first direction D1, and the pair of second base clamping plates U40 may be disposed at the second break F2 in parallel to the first direction D1 and overlapped with the pair of second intermediate clamping plates U30 respectively. Thereby, after the relative fixed connection, for example, locking of the first reinforcing plate R1, the first intermediate clamping plate U10 and the first base clamping plate U20, the first narrow portion 215 can be clamped and restrained in the vertical direction DT by the first reinforcing plate R1 and the first base clamping plate U20, and the first narrow portion 215 can be clamped and restrained in the second direction D2 by the pair of first intermediate clamping plates U10, thereby improving the positioning stability of the first narrow portion 215 without directly locking to the first narrow portion 215 and maintaining the weakened characteristics of the independent structure of the first narrow portion 215. Similarly, after the second reinforcing plate R2, the second intermediate clamp plate U30 and the second base clamp plate U40 are relatively fixed, for example, locked, the second narrow portion 225 can be clamped and restrained in the vertical direction DT by the second reinforcing plate R2 and the second base clamp plate U40, and the second narrow portion 225 can be clamped and restrained in the second direction D2 by the pair of second intermediate clamp plates U30, thereby improving the positioning stability of the second narrow portion 225 without directly locking it to the second narrow portion 225 and maintaining the weakened characteristics of the second narrow portion 225 independent structure.

As described above, the first reinforcing plate R1 and the pair of first intermediate clamping plates U10 and the pair of first base clamping plates U20 are fixedly connected to each other, so that the first narrow portion 215 can be clamped and restrained between the first reinforcing plate R1 and the pair of first base clamping plates U20 along the vertical direction DT; and the second reinforcing plate R2 and the pair of second intermediate clamping plates U30 and the pair of second base clamping plates U40 They are fixedly connected to each other so that the second narrow portion 225 can be clamped and constrained between the second reinforcing plate R2 and the pair of second base clamps U40 along the vertical direction DT, so that the first narrow portion 215 disposed on and suspended by the first break F1 and the second narrow portion 225 disposed on and suspended by the second break F2 can be further supported and positioned to reduce or avoid misalignment.

Referring to FIG. 1 and FIG. 2 , according to various embodiments of the present invention, the fixed connection can be achieved by various means such as, but not limited to, locking bolts and nuts through lock holes. These possible fixed connection means will not be described in detail here. In addition, according to the present embodiment, the building structure 10 may further include a pair of first connecting plates 310 (i.e., lug structures) protruding in parallel from the first side surface S1 of the column structure CL along the first direction D1, and fixedly connected or integrally formed with the column structure CL. As above, the side of the end of the web 110 in the first direction D1 may be disposed between the pair of first connecting plates 310, and fixedly connected to the column structure CL by being fixedly connected to the pair of first connecting plates 310 (e.g., locked relative to each other). However, according to other embodiments of the present invention, other methods or combinations of other methods may be used to directly or indirectly fix the web 110 to the column structure CL (such as welding), and the clamping and locking by the first connecting plate 310 specifically described herein is only a state according to one embodiment of the present invention and is not limited thereto.

Next, an exemplary process of constructing a beam-column joint AT and a building structure 10 including the same according to an embodiment of the present invention will be described with reference to FIGS. 3 to 5 .

As mentioned above, referring to FIG. 3, according to the present embodiment, in the building structure 10' still under construction, the beam-column joint AT can be configured on a first side surface S1 of the column structure CL to connect the required beam structure. A person with ordinary knowledge in the relevant technical field should be able to understand that the same or similar configuration can also be performed on other sides of the column structure CL, and will not be repeated in this article. As mentioned above, the web 110 of the joint structure 100 can be correspondingly arranged between the parallel first connecting plates 310 connected to the column structure CL and protruding from the first side surface S1, and locked with each other through bolt holes, so that the joint structure 100 is fixedly connected to the column structure CL.

Next, referring to FIG. 4 together with FIG. 3 , the first cover plate 210 and the second cover plate 220 can be respectively covered on the first wing plate W1 and the second wing plate W2 of the installed joint structure 100 in opposite directions. As mentioned above, in this process, the first narrow portion 215 of the first cover plate 210 is aligned with the first break F1 of the first wing plate W1 and the first cover plate 210 is locked on the first end block W12 and the first extension block W14 using bolts and screw holes. Similarly, the second narrow portion 225 of the second cover plate 220 is aligned with the second break F2 of the second wing plate W2 and the second cover plate 220 is locked on the second end block W22 and the second extension block W24 using bolts and screw holes.

As shown in Fig. 4, taking the first narrow portion 215 as an example, it can be seen that the width TH1' of the first narrow portion 215 is smaller than the width TH1 of the main portion of the first cover plate 210 fixedly locked to the first wing plate W1. According to some embodiments, the width TH1' of the first narrow portion 215 allows the first narrow portion 215 to at least partially cover the first fracture F1. In addition, according to some other embodiments, the mutually stacked first cover plate 210 and the first wing plate W1 may have the same or similar width, and the mutually stacked second cover plate 220 and the second wing plate W2 may have the same or similar width, so that the width of the relatively narrowed first narrow portion 215 is smaller than the width of the first break F1 of the first wing plate W1 and/or the width of the relatively narrowed second narrow portion 225 is smaller than the width of the second break F2 of the second wing plate W2. However, the above is only an example, and other embodiments according to the present invention are not limited thereto.

Next, referring to FIG. 5 together with FIG. 4, the first reinforcing plate R1 may be covered on the first narrow portion 215, and a pair of first intermediate clamping plates U10 for clamping the first narrow portion 215 and a pair of first base clamping plates U20 overlapping the pair of first intermediate clamping plates U10 may be arranged on both sides corresponding to the second direction D2, so as to enhance the positioning accuracy and structural stability of the first narrow portion 215 which is easier to be misplaced due to structural weakening. Similarly, the second reinforcing plate R2 can be covered on the second narrow portion 225, and a pair of second intermediate clamping plates U30 for clamping the second narrow portion 225 and a pair of second base clamping plates U40 overlapping the pair of second intermediate clamping plates U30 can be arranged on both sides corresponding to the second direction D2, so as to enhance the positioning accuracy and structural stability of the second narrow portion 225 which is easy to be misplaced due to structural weakening. In accordance with the above, by means of this arrangement, when an impact such as an earthquake occurs, stress can be guided to concentrate at an expected position to reduce or avoid damage to other important structures of the beam-column joint AT and the building structure 10. In addition, according to this structure, even if the first narrow portion 215 and/or the second narrow portion 225 or the first reinforcing plate R1 and/or the second reinforcing plate R2 assembled therewith are damaged, the entire beam-column joint AT and the building structure 10 can be repaired by directly replacing a part or all of the components of the cover plate structure 200, while reducing or avoiding the need to disassemble the joint structure 100. Therefore, the post-earthquake repair process can be simplified and accelerated, and the materials required for repair can be reduced.

Hereinafter, some modified embodiments of the present invention will be further described. As mentioned above, these embodiments will only focus on the differences from the embodiments described above with reference to FIGS. 1 to 5 , and the same or similar details will not be repeated.

Referring to FIGS. 6 to 8 , there is shown an exemplary construction process similar to that described above with reference to FIGS. 3 to 5 for completing the final building structure 20 from the building structure 20’ still under construction. Continuing from the above, according to the present embodiment, a column joint AT’ different from the above-mentioned column joint AT may be provided. The web 110 of the joint structure 100 of the column joint AT’ may have a recessed portion 115 at a position corresponding to the first break F1 (or corresponding to the second break F2), and the recessed portion 115 is recessed relative to the main body 110’ of the web 110, so that the thickness of the recessed portion 115 in a direction parallel to the width of the first narrow portion 215 (e.g., in the second direction D2) is reduced. Thereby, the structures corresponding to the first narrow portion 215 and the second narrow portion 225 can be further weakened, and when subjected to vibration or impact, the stress can be more easily guided to the first narrow portion 215 and the second narrow portion 225 in accordance with the thinned recessed portion 115. Therefore, when subjected to vibration or impact, the stress pressure can be more easily concentrated on the first narrow portion 215 and the second narrow portion 225 than on other parts, so that the possible damage occurs at the expected position and the damage to other important structures is reduced or avoided.

Next, referring to the corresponding structural diagram of each component in FIG. 9 and the completed structural diagram of each component in FIG. 10 , the difference between the building structure 30 and the beam-column joint AT″ included therein according to another embodiment of the present invention and the above-mentioned building structure 10 and the beam-column joint AT included therein is that the first break F1 and the second break F2 can correspond to the edges of the first narrow portion 215 and the second narrow portion 225 close to the first side surface S1, respectively. In detail, As shown in FIG. 9 , the first break F1 and the second break F2 are not arranged in the middle in alignment with the first narrow portion 215 and the second narrow portion 225, but are relatively biased toward the first side surface S1. As mentioned above, the web 110 is aligned with the first break F1 and the second break F2 to form a pair of narrow grooves G10 recessed from the two ventral surfaces of the web 110, and the web 110 can be divided into a connecting portion 112 close to the first side surface S1 and a connecting portion far from the first side surface S1 based on the pair of narrow grooves G10. The extension portion 114 of the first side surface S1. The connection portion 112 can be stably fixedly connected to the column structure CL (for example, it can be integrally formed with the column structure CL or welded to the column structure CL), and the connection portion 112 and the extension portion 114 are further fixedly connected to each other. For example, the building structure 30 can further include a pair of first connection plates 310, and the pair of first connection plates 310 are parallel to the two belly surfaces of the web 110 and correspond to the two belly surfaces respectively. Therefore, the pair of first connecting plates 310 are respectively across one of the pair of narrow grooves G10 and fixedly connected to the web 110, so that the connecting portion 112 and the extending portion 114 of the web 110 are disposed between the pair of first connecting plates 310, and the connecting portion 112 and the extending portion 114 sandwiched between the pair of first connecting plates 310 can be fixedly connected, for example, by indirectly locking the pair of first connecting plates 310.

Based on the above structure, according to this embodiment, compared with the above-mentioned beam-column joint AT and building structure 10, since the first cutout F1 and the second cutout F2 are relatively biased toward the first side surface S1 and are narrower, the first narrow portion 215 and the second narrow portion 225 can be at least partially supported by the first wing plate W1 and the second wing plate W2, respectively. Therefore, the supporting and positioning properties of the first narrow portion 215 and the second narrow portion 225 can be enhanced while achieving the pre-structural weakening of the above-mentioned first narrow portion 215 and the second narrow portion 225.

As mentioned above, in this state, the cover plate structure 200 may further include only the first reinforcing plate R1 and a pair of first intermediate clamping plates U10, and the second reinforcing plate R2 and a pair of second intermediate clamping plates U30. In particular, referring to FIG. 10 together with FIG. 9, the first reinforcing plate R1 may overlap and cover the first narrow portion 215 and be disposed on a surface of the first narrow portion 215 that is away from the first wing plate W1, and the pair of first intermediate clamping plates U10 are disposed on both sides of the first narrow portion 215 parallel to the first direction D1. In addition, the second reinforcing plate R2 can overlap and cover the second narrow portion 225 and be disposed on a surface of the second narrow portion 225 that is opposite to the second wing plate W2, and the pair of second intermediate clamping plates U30 are disposed on both sides of the second narrow portion 225 parallel to the first direction D1. With this configuration, the first reinforcing plate R1 and the pair of first intermediate clamping plates U10 can be fixedly connected to each other, so that the first narrow portion 215 can be clamped and restrained between the first reinforcing plate R1 and the first wing plate W1 along the vertical direction DT, and the second reinforcing plate R2 and the pair of second intermediate clamping plates U30 can be fixedly connected to each other, so that the second narrow portion 225 can be clamped and restrained between the second reinforcing plate R2 and the second wing plate W2 along the vertical direction DT.

According to the present embodiment, since the first break F1 is not aligned with the first narrow portion 215 and the second break F2 is not aligned with the second narrow portion 225 , damage caused by stress pressure can be reduced or prevented from further extending to the web 110 along the first narrow portion 215 and the second narrow portion 225 . In addition, even if the extension portion 114 of the web 110 corresponding to the center of the first narrow portion 215 and the second narrow portion 225 is damaged, since the connecting portion 112 and the extension portion 114 are not formed in one piece and can be disassembled accordingly, the beam-column joint AT" and the building structure 30 can be replaced or repaired while reducing or avoiding the need to disassemble and reconstruct the connecting portion 112 and the column structure CL.

According to some embodiments of the present invention, the above-mentioned structure corresponding to the column structure CL can also be similarly or identically arranged on the beam structure BL (for example, but not limited to, H-shaped steel structure or column steel structure). For example, referring to the corresponding structure diagram of each component in FIG11 and the completed construction diagram of each component in FIG12, according to another embodiment of the present invention, a building structure 40 with a replaceable beam-column joint BT can include a beam structure BL extending along a transverse direction DH and having at least a first surface S1', and a beam-column joint BT having a joint structure 100 and a cover plate structure 200. As described above, the joint structure 100 extends along the vertical direction DT intersecting the transverse direction DH and has a web 110, a first wing plate set W10 extending from the first surface S1' and connected to the first side edge E1 of the web 110, and a second wing plate set W20 extending from the first surface S1' and connected to the second side edge E2 of the web 110.

Specifically, according to the present embodiment, the end of the web 110 in the vertical direction DT can be fixedly connected to the beam structure BL, and in order to further strengthen the support for the beam structure BL in the vertical direction DT, a first wing plate set W10 and a second wing plate set W20 can be provided on both sides of the web 110. As described above, the first wing plate set W10 facing away from the web 110 can sequentially include a first supporting wing plate P1, a first side wing web plate K1 provided on the first supporting wing plate P1, and a first wing plate W1 provided on the first side wing web plate K1. Similarly, the second wing set W20 may have a second supporting wing P2, a second side wing web K2 disposed on the second supporting wing P2, and a second wing W2 disposed on the second side wing web K2 in sequence facing the web 110. In addition, according to some embodiments, in order to increase the connection between the web 110 and the first wing set W10 and the second wing set W20 on both sides, a connecting plate 350 extending along the transverse direction DH may be further provided, and the connecting plate 350 extends across the web 110 and the first wing set W10 and the second wing set W20 on both sides to be locked and fixedly connected to each other.

Based on the above structure, according to this embodiment, the support for the weight of the beam structure BL can be further increased. However, this is only an example, and according to other embodiments, under the condition that the support for the beam structure BL is sufficient, the building structure 40 and the beam column joint BT can also be similar to the above other embodiments, and only the first wing plate W1 and the second wing plate W2 are respectively provided on both sides of the web 110, instead of the first wing plate set W10 and the second wing plate set W20. As above, the repeated details of similar aspects will not be repeated here.

Continuing to refer to FIG. 11 and FIG. 12 , according to this embodiment, similar to the other embodiments described above, the cover plate structure 200 may include a first cover plate 210 and/or a second cover plate 220 covering the first wing plate W1 and/or the second wing plate W2 along the vertical direction DT. Based on the above, the first cover plate 210 may be fixed on the first wing plate W1 and have a first narrow portion 215, and the width of the first narrow portion 215 is smaller than the width of other parts of the first cover plate 210 except the first narrow portion 215. In addition, the second cover plate 220 may be fixed on the second wing plate W2 and have a second narrow portion 225, and the width of the second narrow portion 225 is smaller than the width of other parts of the second cover plate 220 except the second narrow portion 225. In addition, the first side wing web K1 and the second side wing web K2 may not be directly connected to the beam structure BL or may only be partially directly connected to the beam structure BL. Therefore, when an impact or vibration occurs, the first narrow portion 215 and the second narrow portion 225, which are relatively structurally weakened, can correspondingly guide or absorb the stress pressure (such as the stress of beam column misalignment) caused by the impact or vibration. In this way, the damage may be limited to the expected position and reduce or avoid damage to other important structures. In addition, when damage occurs to the first narrow portion 215 and the second narrow portion 225, the entire beam-column joint BT and the building structure 40 can be replaced or repaired relatively simply by replacing part or all of the components of the cover plate structure 200, thereby simplifying and accelerating the post-earthquake restoration project.

According to some embodiments, the cover plate structure 200 of FIG. 11 and FIG. 12 may further include a first reinforcing plate R1 and a pair of first intermediate clamping plates U10 corresponding to the first cover plate 210, and may further include a second reinforcing plate R2 and a pair of second intermediate clamping plates U30 corresponding to the second cover plate 220. As mentioned above, the first reinforcing plate R1 overlaps and covers the first narrow portion 215 and is disposed on a surface of the first narrow portion 215 that is opposite to the first wing plate W1, and the pair of first intermediate clamping plates U10 are disposed on both sides of the first narrow portion 215 along the transverse direction DP parallel to the vertical direction DT. In addition, the second reinforcing plate R2 overlaps and covers the second narrow portion 225 and is disposed on a surface of the second narrow portion 225 that is opposite to the second wing plate W2, and the pair of second intermediate clamping plates U30 are disposed parallel to the vertical direction DT on both sides of the second narrow portion 225 along the transverse direction DP. In this way, the first reinforcing plate R1 and the pair of first intermediate clamping plates U10 can be fixedly connected to each other, and the second reinforcing plate R2 and the pair of second intermediate clamping plates U30 can be fixedly connected to each other, so that the first narrow portion 215 is clamped and restrained between the first reinforcing plate R1 and the first wing plate W1 along the transverse direction DH, and the second narrow portion 225 is clamped and restrained between the second reinforcing plate R2 and the second wing plate W2 along the transverse direction DH. As mentioned above, this structure can further enhance the stability and positioning of the first narrow portion 215 and the second narrow portion 225, which have weakened structures. Similar details can be understood by referring to the corresponding descriptions of the other embodiments mentioned above, and will not be elaborated here.

In addition, the beam-column joint BT and the building structure 40 according to the present embodiment further include a first support plate 218 corresponding to the first cover plate 210, and a second support plate 228 corresponding to the second cover plate 220. In detail, the end of the first cover plate 210 close to the first surface S1' can be connected to the first support plate 218 parallel to the first surface S1' of the beam structure BL (for example, but not limited to, it can be formed in one piece), and the end of the second cover plate 220 close to the first surface S1' can be connected to the second support plate 228 parallel to the first surface S1' of the beam structure BL (for example, but not limited to, it can be formed in one piece). Based on the above, the first support plate 218 can be fixedly connected, for example, but not limited to, locked to the beam structure BL, and the second support plate 228 can be fixedly connected, for example, but not limited to, locked to the beam structure BL. Thus, the support of the beam structure BL can be further enhanced by the arrangement of the first support plate 218 and the second support plate 228. In addition, the stability and positioning of the first cover plate 210 and the second cover plate 220 can be further enhanced by the first support plate 218 and the second support plate 228 fixedly connected to the beam structure BL.

Furthermore, according to some embodiments, in the assembled structure as shown in FIG. 12 , the first wing W1 may have a first spacing M1 with the first surface S1′, and the first support plate 218 may be partially inserted into the first spacing M1. Similarly, the second wing W2 may have a second spacing M2 with the first surface S1′, and the second support plate 228 may be partially inserted into the second spacing M2. In this way, the stress and pressure transmitted through the beam structure BL can be at least partially reduced or avoided from directly entering the joint core (e.g., the web 110) of the beam structure BL and the beam column joint BT, and the possible stress and pressure can be at least partially guided into the first cover plate 210 and the second cover plate 220 through the first support plate 218 and the second support plate 228 connecting the beam structure BL. Based on the above, even if the first cover plate 210 and the second cover plate 220 are damaged, for example, the first narrow portion 215 and the second narrow portion 225 are damaged, the beam joint BT and the building structure 40 can be repaired by replacing partial or complete components of the outer cover plate structure 200, while reducing or avoiding the need to disassemble and replace the joint core of the beam joint BT.

Next, a building structure 50 and a beam joint BT' included therein according to another embodiment of the present invention will be described with reference to FIG. 13 .

As described above, the difference between the beam joint BT' and the building structure 50 according to the present embodiment and the above-mentioned beam joint BT and the building structure 40 is that the first wing plate W1 may have a first break F1 and be divided into a first end block W12 relatively close to the first surface S1' and a first extension block W14 relatively far from the first surface S1'. Similarly, the second wing plate W2 may have a second break F2 and be divided into a second end block W22 relatively close to the first surface S1' and a second extension block W24 relatively far from the first surface S1'. Among them, the first narrow portion 215 of the first cover plate 210 can be set corresponding to the first break F1, so that the first cover plate 210 extends across the first break F1 and faces and is fixedly connected (for example, locked) to the first end block W12 and the first extension block W14, and the second narrow portion 225 of the second cover plate 220 can be set corresponding to the second break F2, so that the second cover plate 220 extends across the second break F2 and faces and is fixedly connected (for example, locked) to the second end block W22 and the second extension block W24.

In addition, according to this embodiment, a pair of first base clamps U20 corresponding to the first cover plate 210 and disposed at the first break F1, and a pair of second base clamps U40 corresponding to the second cover plate 220 and disposed at the second break F2 may be further included, thereby enhancing the positioning and stability of the first narrow portion 215 and the second narrow portion 225. These details are similar to the other embodiments described above, and the repetitive contents will not be repeated here.

As described above, similar to the description with reference to the beam joints AT, AT' and AT", according to the beam joint BT' and the building structure 50 of the present embodiment, when the first narrow portion 215 and the second narrow portion 225 of the structure are damaged by the guided stress pressure, additional damage to the first wing plate W1 and the second wing plate W2 can be reduced or avoided. In this way, the damage can be generated at the expected position, such as the first narrow portion 215 and the second narrow portion 225. The first narrow portion 215 and the second narrow portion 225 can reduce or avoid the need to dismantle and replace the core parts of the beam joint BT', such as the joint structure 100 and the first wing plate set W10 and the second wing plate set W20, when repairing the beam joint BT' and the building structure 50. Therefore, the earthquake resistance of the entire beam joint BT' and the building structure 50 can be improved, and the repairability of damage after vibration and impact can be improved.

In summary, the beam-column joints and building structures including the same according to the various embodiments of the present invention can enhance the earthquake resistance of the entire beam-column joint and building structure, and can relatively guide the stress pressure to the expected position when a vibration or impact occurs, thereby reducing or avoiding damage to other important structures such as the intersection of beams and columns. In addition, the beam-column joints and building structures including the same according to the various embodiments of the present invention can be more conveniently disassembled for replacement or repair because the structural parts that are more easily induced to be damaged are relatively separated from the core parts of the beam-column joints or the column structure and the beam structure. In this way, the repair of the entire beam-column joint and the building structure can be completed more quickly while reducing or avoiding the need to disassemble other core parts or column structures and beam structures of the beam-column joint, and the materials consumed in the repair can be reduced or avoided. As mentioned above, according to the various embodiments of the present invention, a beam-column joint with relatively high earthquake resistance, repairability and lifespan and a building structure including the same can be provided, thereby reducing or avoiding structural damage and property or even human life losses caused by vibration or impact.
