Description

Reinforcement system construction method

The present invention relates to a method for constructing a steel reinforcement system. In particular, the present invention relates to a method for constructing a steel reinforcement system comprising an upper layer of main reinforcement for a side spar, and further comprising external stirrups and a lower layer of main reinforcement for the spar.

As the core structure of a building, the steel bar system must have the expected stability and reliability. As mentioned above, in conventional beam-column design, it is usually necessary to install complex and staggered steel bars such as main bars, stirrups or ties to ensure the required stability and reliability. However, in an existing steel bar structure, it is quite difficult to further insert or stack long steel bars such as beam main bars. In particular, in a steel bar system with beam-column joints, it is often limited by the beam-column joint structure that must be passed through in the middle, which makes the insertion and positioning of new steel bars encounter many restrictions and inconveniences. As mentioned above, long extension steel bars usually require manual and meticulous setting of specific insertion angles, and require time-consuming adjustments when crossing the gaps between existing structures. Therefore, as construction works continue, the complexity and difficulty of subsequent construction work for such projects may continue to increase.

As mentioned above, in order to reduce or avoid the complexity and difficulty of such projects and reduce reliance on the skills and experience of on-site construction workers, it is necessary to develop new construction methods or processes to improve and simplify the construction of the steel reinforcement system, or to reduce or avoid the need to insert such long steel bars or complex steel bars. This can reduce or avoid the complexity and/or difficulty of the construction process and improve the reliability and stability of the constructed steel reinforcement system.

Technical means to solve the problem

To solve the above problem, according to one embodiment of the present invention, a method for constructing a steel bar system is proposed, which includes the following steps: a column module construction step, arranging a plurality of column main bars in a first direction and a second direction perpendicular to each other, thereby constructing a column module, wherein the column main bars extend along a third direction perpendicular to the first direction and the second direction, and the column module is divided into at least a joint section and an extension section above the joint section along the third direction; a beam-column joint stirrup installation step, installing the beam-column joint stirrups on the extension section; a side spar upper layer main bar installation step, positioning a pair of first side spar upper layer main bars corresponding to the top of the joint section. The reinforcement is arranged on the column module, and the upper main reinforcement of the pair of first side wing beams extends parallel to the first direction and back to the column module without passing through the joint section; the outer stirrup hanging step is to arrange a plurality of first outer stirrups along the first direction, wherein each of the first outer stirrups has a bottom section and a pair of side sections standing upright from both ends of the bottom section, and the pair of side sections are respectively positioned on the upper main reinforcement of the pair of first side wing beams; and the beam lower layer main reinforcement setting step is to extend the plurality of first beam lower layer main reinforcements continuously along the first direction through the joint section, so that the first beam lower layer main reinforcements are supported by the bottom sections of the first outer stirrups.

Comparison with the effectiveness of previous technologies

The reinforcement system construction methods provided by various embodiments of the present invention can increase the clearance between beam-column joints, simplify and optimize the working space for reinforcing bars, and enhance the convenience and smoothness of construction. Consequently, the construction efficiency and quality of reinforcement systems with beam-column joints can be further improved while maintaining the expected stability and reliability of the reinforcement system.

Various embodiments are described below, and those skilled in the art should be able to readily understand the spirit and principles of the present invention by referring to the accompanying drawings. However, while specific embodiments are described herein, these are intended to be illustrative only and are not to be construed as limiting or exhaustive in any respect. Therefore, various variations and modifications of the present invention should be readily apparent and achievable by those skilled in the art without departing from the spirit and principles of the present invention.

Hereinafter, the process steps of the construction method of the steel bar system according to one embodiment of the present invention will be described in sequence with reference to Figures 1 to 13.

First, referring to FIG1 , a method for constructing a steel reinforcement system according to one embodiment of the present invention may include a column module construction step S10 and a beam-column joint stirrup installation step S20. Specifically, as shown in FIG1 , according to this embodiment, in the column module construction step S10 , a plurality of column main bars 105 may be arranged in a first direction D1 and a second direction D2 that are perpendicular to each other, thereby constructing a column module 100. Specifically, these column main bars 105 may extend along a third direction D3 that is perpendicular to the first direction D1 and the second direction D2. This arrangement of these column main bars 105 results in a columnar structure 100 extending along the third direction D3.

As described above, the constructed column module 100 can be divided along the third direction D3 into at least a joint section 110 where the beam-column joint is intended to be located, and an extended section 120 above the joint section 110. In the beam-column joint stirrup installation step S20, the beam-column joint stirrups 200 can be installed on the extended section 120, thereby binding and at least partially securing the column module 100 in place or constraining it.

Next, referring to Figure 2 , the side spar upper main reinforcement placement step S30 can be performed. Specifically, a pair of first side spar upper main reinforcements 310 extending along the first direction D1 can be positioned on the column module 100, corresponding to the top of the joint section 110, to prepare for forming a beam structure extending along the first direction D1. As described above, the pair of first side spar upper main reinforcements 310 can extend parallel to and away from the column module 100 on one side or two opposing sides of the column module 100, to prepare for forming a beam structure extending along the first direction D1. As shown in FIG2 , the pair of first side spar upper main bars 310 can be fixed or tied to one or more column main bars 105 on one side or two opposite sides of the column module 100, and can extend parallel to the first direction D1 and away from the column module 100 without passing through the joint section 110. Similarly, according to this embodiment, a pair of second side spar upper main bars 320 can be further provided, extending parallel to the second direction D2 and away from the column module 100 on one side or two opposite sides of the column module 100 without passing through the joint section 110. In this way, a beam structure extending along the second direction D2 can be prepared. As mentioned above, according to the side spar upper layer main reinforcement setting step S30, the initial structure of the beam structure can be constructed relative to the column module 100 without forming the beam-column joint through the joint section 110.

Next, referring to FIG3 , an external stirrup hanging step S40 may be performed. For example, corresponding to the pair of first side spar upper main bars 310 , a plurality of first external stirrups 410 may be arranged along the first direction D1. As described above, each of the first external stirrups 410 may be a U-shaped structure and vertically hung on the pair of first side spar upper main bars 310 . Specifically, each of the first external stirrups 410 may have a bottom section BB and a pair of side sections SB extending vertically from both ends of the bottom section BB. The pair of side sections SB may be positioned respectively on the pair of first side spar upper main bars 310 . For example, the top ends of the pair of side parts SB may have hooks and be arranged along the first direction D1 and hung on the pair of first side spar upper main bars 310, so that the first outer stirrups 410 are vertically arranged along the first direction D1 between the pair of first side spar upper main bars 310.

According to some embodiments, the beam structure of the intended structure can be divided into a corner molding area K1 close to the column module 100 and relatively easy to deform, and a non-corner molding area K2 far from the column module 100 and relatively difficult to deform. Continuing from the above, a plurality of first external stirrups 410 that are relatively stable or high-strength can be provided in the block corresponding to the corner molding area K1. Alternatively, a plurality of first external stirrups 410 with a higher density can be provided in the block corresponding to the corner molding area K1. In addition, according to some embodiments, the corner molding area K1 can be a block extending from the side of the column module 100 along the first direction D1 or the second direction D2 within a range of approximately twice the height of the joint section 110, but is not limited thereto. In addition, the above-mentioned aspects are merely examples, and according to other embodiments of the present invention, it is also possible to set the same first outer stirrups 410 or the first outer stirrups 410 with the same density in the plastic corner area K1 and the non-plastic corner area K2, and these variations will not be described in detail here.

As described above, a plurality of first external stirrups 410 may be mounted on the first side spar upper main bar 310 along the first direction D1. Similarly, a plurality of second external stirrups 420 may be mounted on the second side spar upper main bar 320 along the second direction D2. The same or similar details will not be repeated here.

4 , according to some embodiments, after the plurality of first outer stirrups 410 and/or the plurality of second outer stirrups 420 are installed, before proceeding to the next step (beam lower layer main reinforcement installation step S60 described below), an inner stirrup installation step S50 may be performed. Specifically, in the inner stirrup installation step S50 , a plurality of first inner stirrups 510 may be arranged along the first direction D1 within the first outer stirrup openings OP1 defined by the first outer stirrups 410 , such that the first inner stirrups 510 are supported by the bottom portions BB of the first outer stirrups 410 . Similarly, a plurality of second inner stirrups 520 may be arranged along the second direction D2 within the second outer stirrup openings OP2 defined by the second outer stirrups 420, such that the second inner stirrups 520 are supported by the bottom portions BB of the second outer stirrups 420. Continuing with the above, according to some embodiments, the first inner stirrups 510 or the second inner stirrups 520 may be relatively positioned in the corner molding area K1 or arranged at a higher density in the corner molding area K1 to ensure the stability and reliability of the easily deformable corner molding area K1. However, the above is merely an example, and other embodiments of the present invention are not limited thereto.

As shown in FIG4 , according to some embodiments, each of the first inner stirrups 510 may be respectively U-shaped. Continuing from the above, the first inner stirrups 510 may define a first inner stirrup opening AP1, such that the first inner stirrup opening AP1 and the first outer stirrup opening OP1 are both open upward. Similarly, each of the second inner stirrups 520 may be respectively U-shaped and may define a second inner stirrup opening AP2, such that the second inner stirrup opening AP2 and the second outer stirrup opening OP2 are both open upward. In addition, the first inner stirrups 510 may be connected by at least one first inner stirrup tie 515 and the second inner stirrups 520 may be connected by at least one second inner stirrup tie 525 to enhance their mutual positioning and relative connection stability and structural strength. However, the specific forms and relative connection configurations of the first inner stirrup 510 and the second inner stirrup 520 described above are merely examples, and other embodiments of the present invention are not limited thereto.

Next, referring to FIG. 5 , according to one embodiment, after the outer stirrup mounting step S40 and the optional inner stirrup placement step S50, a beam lower layer main reinforcement placement step S60 may be performed. A plurality of first beam lower layer main reinforcement bars 610 may be passed through the remaining gap in the joint section 110 (e.g., entering the joint section 110 through the first outer stirrup opening OP1) and placed on the first outer stirrups 410. As described above, the plurality of first beam lower layer main reinforcement bars 610 extend continuously along the first direction D1 through the joint section 110, such that the first beam lower layer main reinforcement bars 610 are supported by the bottom portion BB of the first outer stirrups 410. Similarly, a plurality of second beam lower layer main bars 620 can be passed through the joint section 110 (e.g., entering the joint section 110 through the second outer stirrup opening OP2) and placed on the second outer stirrups 420. Continuing from the above, the plurality of second beam lower layer main bars 620 extend continuously through the joint section 110 along the second direction D2, such that the second beam lower layer main bars 620 are supported by the bottom sections BB of the second outer stirrups 420.

According to some embodiments, when the first inner stirrups 510 are provided, a plurality of first beam lower layer main bars 610 may be stacked and disposed on the first inner stirrups 510 or arranged in parallel with the first inner stirrups 510. Similarly, when the second inner stirrups 520 are provided, a plurality of second beam lower layer main bars 620 may be stacked and disposed on the second inner stirrups 520 or arranged in parallel with the second inner stirrups 520.

As described above, according to this embodiment, because the joint section 110 is not provided with beam-column joint stirrups 200 and other beam upper main bars, a relatively large gap is retained, making it relatively easy to pass the first beam lower main bars 610 and/or the second beam lower main bars 620 through the joint section 110. Therefore, according to this embodiment, the construction process of arranging the first beam lower main bars 610 and/or the second beam lower main bars 620 becomes easier and more convenient. Furthermore, this process can reduce or avoid the need to insert the first beam lower layer main bars 610 and/or the second beam lower layer main bars 620 at specific concave angles, thereby reducing or avoiding damage or deformation of the first beam lower layer main bars 610 and/or the second beam lower layer main bars 620, thereby improving the structural stability and reliability of the final reinforcement system.

Next, referring to FIG. 6 , after completing the beam lower layer main reinforcement placement step S60 , a beam-column joint stirrup adjustment step S70 can be performed. Specifically, in the beam-column joint stirrup adjustment step S70 , at least a portion or all of the beam-column joint stirrups 200 can be moved from the extension section 120 to the joint section 110 . For example, at least a portion or all of the beam-column joint stirrups 200 surrounding the column module 100 can be gradually slid along the third direction D3 from the extension section 120 to the joint section 110 . Furthermore, to maintain the configuration of the extension section 120 of the column module 100 , additional beam-column joint stirrups 200 may be optionally added to the vacant extension section 120 during this process. Alternatively, it is also possible to directly add the remaining additional beam-column joint stirrups 200 to the joint section 110. As mentioned above, in this step S70 of adjusting the beam-column joint stirrups, the beam-column joint stirrups 200 can be installed on the column module 100 corresponding to the joint section 110 based on various methods.

Continuing with the above, referring again to FIG7 , beam-column joint ties 800 can be further installed on the column module 100 of the joint section 110, corresponding to the beam-column joint stirrups 200. That is, after the beam-column joint stirrup adjustment step S70 is completed, a beam-column joint tie installation step S80 can be performed to install corresponding beam-column joint ties 800 on the beam-column joint stirrups 200. Further referring to FIG8 , according to the beam-column joint stirrup adjustment step S70 and the beam-column joint tie installation step S80 described above, the beam-column joint 250 corresponding to the joint section 110 can be completed.

As described above, referring to FIG8 , after the beam-column joint 250 is installed, for example, after the beam-column joint tie reinforcement installation step S80 is completed, a beam upper main reinforcement installation step S90 can be performed. Continuing from the above, in the beam upper main reinforcement installation step S90, a plurality of first beam upper main reinforcement bars 910 can be placed on the beam-column joint 250 and extended along the first direction D1. Specifically, the plurality of first beam upper main reinforcement bars 910 can be arranged between the pair of first side spar upper main reinforcement bars 310, extending continuously and in parallel along the first direction D1 through the joint section 110, and supported by the beam-column joint stirrups 200 of the beam-column joint 250. Similarly, a plurality of second beam upper main bars 920 may be placed on the beam-column joint 250 and extend along the second direction D2. For example, the plurality of second beam upper main bars 920 may be disposed between the pair of second side spar upper main bars 320, extending continuously and in parallel along the second direction D2 through the joint section 110, and supported by the beam-column joint stirrups 200 of the beam-column joint 250.

Next, referring to FIG. 9 , according to this embodiment, after the beam upper main reinforcement arrangement step S90 is completed, a main reinforcement connection step S100 may be performed. As described above, in the main reinforcement connection step S100, a pair of first main reinforcement connection members R1 may be respectively connected to the pair of first side spar upper main reinforcements 310 and disposed through the joint section 110. Similarly, a pair of second main reinforcement connection members R2 may be respectively connected to the pair of second side spar upper main reinforcements 320 and disposed through the joint section 110. Specifically, a pair of first main reinforcement connectors R1 may extend along a first direction D1 and be disposed in the joint section 110, thereby connecting the pair of first side spar upper main reinforcements 310 on both sides of the column module 100 separated by the joint section 110. Similarly, a pair of second main reinforcement connectors R2 may extend along a second direction D2 and be disposed in the joint section 110, thereby connecting the pair of second side spar upper main reinforcements 320 on both sides of the column module 100 separated by the joint section 110.

Continuing from the above, as shown in FIG10 , after the first main reinforcement connector R1 and the second main reinforcement connector R2 are installed, the previously disconnected upper main reinforcement 310 of the first side spar can be connected and continuously extended along the first direction D1, and the previously disconnected upper main reinforcement 320 of the second side spar can be connected and continuously extended along the second direction D2.

Next, referring to Figures 10 and 11, after the main reinforcement splicing step S100 is completed, a beam-column joint fixing step S102 can be performed. In detail, in the beam-column joint fixing step S102, a positioning upper layer stirrup Q1, a positioning upper layer tie Q2, or a combination thereof can be further provided on the beam-column joint 250 already provided in the joint section 110 (for example, on the beam-column joint stirrup 200 provided on the beam-column joint 250) to jointly clamp the pair of first main reinforcement connectors R1 and/or the pair of second main reinforcement connectors R2, as well as a plurality of first beam upper layer main reinforcements 910 and a plurality of second beam upper layer main reinforcements 920 with the beam-column joint 250 (for example, the beam-column joint stirrup 200 provided on the beam-column joint 250).

Referring to FIG. 12 , after completing the main reinforcement splicing step S100 and the further beam-column joint fixing step S102 as described above, a reinforcement system structure having continuous upper beam main reinforcement and a beam-column joint 250 is completed. Based on the above, a beam module fixing step S104 may be optionally performed to arrange a plurality of first upper layer inner stirrups 530 along the first direction D1 and/or a plurality of second upper layer inner stirrups 540 along the second direction D2. As described above, the plurality of first upper layer inner stirrups 530 are arranged within the first outer stirrup openings OP1 defined by the first outer stirrups 410 and are at least partially supported by the first beam upper layer main reinforcement 910. Similarly, a plurality of second upper layer inner stirrups 540 are disposed within the second outer stirrup openings OP2 defined by the second outer stirrups 420 and are at least partially supported by the second beam upper layer main bars 920 .

According to some embodiments, the first upper layer of internal stirrups 530 and the second upper layer of internal stirrups 540 may be used in conjunction with the first and second upper layer of internal stirrups 510, 520 described above to construct a reinforcement system with desired strength and stability. As previously mentioned, according to this embodiment, each of the first upper layer of internal stirrups 530 may have a U-shape and define a first upper layer of internal stirrup opening AP1'. Similarly, each of the second upper layer of internal stirrups 540 may have a U-shape and define a second upper layer of internal stirrup opening AP2'. In addition, when installing the first upper layer inner stirrups 530, the first upper layer inner stirrup opening AP1' can be opened downward and face the bottom section BB of the first outer stirrups 410, and when installing the second upper layer inner stirrups 540, the second upper layer inner stirrup opening AP2' can be opened downward and face the bottom section BB of the second outer stirrups 420.

As described above, the first upper layer inner stirrup openings AP1' and second upper layer inner stirrup openings AP2' of the first upper layer inner stirrups 530 and second upper layer inner stirrups 540 can substantially face each other with the first inner stirrup openings AP1 and second inner stirrup openings AP2 of the first inner stirrups 510 and second inner stirrups 520 described above, thereby forming a reinforcement system with the desired strength and stability. However, the configuration described herein is merely exemplary, and the types and forms of auxiliary reinforcement structures, such as inner stirrups, and their combination in accordance with other embodiments of the present invention are not limited thereto, provided that the desired strength and stability are achieved.

According to some embodiments, in order to enhance the stability or connectivity of the first upper layer inner stirrups 530 arranged along the first direction D1 and the second upper layer inner stirrups 540 arranged along the second direction D2, the first upper layer inner stirrups 530 may be further connected by at least one first upper layer inner stirrup tie 535 and/or the second upper layer inner stirrups 540 may be connected by at least one second upper layer inner stirrup tie 545.

Next, referring to FIG. 13 , the beam module fixing step S104 may further include arranging a plurality of stirrup caps M along the first direction D1 and/or arranging a plurality of stirrup caps M along the second direction D2. As described above, the plurality of stirrup caps M arranged along the first direction D1 may be mounted on the pair of first side spar upper main bars 310 or the first beam upper main bars 910, thereby more stably maintaining and positioning the entire beam structure extending along the first direction D1. Similarly, a plurality of stirrup caps M arranged along the second direction D2 can be mounted on the pair of second side spar upper main bars 320 or the second beam upper main bars 920, thereby more stably maintaining and positioning the entire beam structure extending along the second direction D2. The stirrup caps M have a cap opening MP facing the bottom sections BB of the first outer stirrups 410 and/or the bottom sections BB of the second outer stirrups 420. This provides additional coverage and fixation of the beam structure from above, thereby enhancing the stability and reliability of the overall beam structure and reinforcement system.

Continuing with FIG. 14 , a complete beam-column structure reinforcement system 1000 can be completed by, for example, the process described above with reference to FIG. 1 through FIG. 13 . As described above, a reinforcement system comprising beam-column joints 250 and interconnected upper beam main bars can be completed by the improved process according to this exemplary embodiment while maintaining the desired reinforcement structure complexity, stability, and reliability. Consequently, the reinforcement system 1000 having the desired beam-column structure can be completed while simplifying construction difficulty and complexity and reducing or avoiding unnecessary buckling or damage to the installed reinforcement bars.

Hereinafter, the process of constructing a steel bar system according to another embodiment of the present invention will be further described with reference to FIG. 15 to FIG. 18 .

As described above, with reference to Figures 15 and 16 , a method for constructing a steel reinforcement system according to another embodiment of the present invention may have a process similar to that described above with reference to Figures 1 to 13 . However, corresponding to the inner stirrup placement step S50 described in Figure 4 , the construction method according to this embodiment may additionally have an inner stirrup placement step S50 ', in which different first inner stirrups 510 ' and second inner stirrups 520 ' may be provided. Specifically, as shown in Figure 15 , according to this embodiment, each of these first inner stirrups 510 ' may have a set of low vertical bars 511 corresponding to one of the pair of first side spar upper main bars 310, and a set of high vertical bars 512 corresponding to the other of the pair of first side spar upper main bars 310. Similarly, each of the second inner stirrups 520' may also have a set of low vertical bars 511 corresponding to one of the upper main bars 320 of the pair of second side wing beams, and a set of high vertical bars 512 corresponding to the other of the upper main bars 320 of the pair of second side wing beams. Continuing from the above, as shown in Figures 15 and 16, the set of high vertical bars 512 and the set of low vertical bars 511 may protrude away from the bottom section BB, and the set of high vertical bars 512 may be connected to each other at the top. In detail, the first inner stirrup 510' or the second inner stirrup 520' may be an inner stirrup similar to an L-shaped configuration. Among them, the high vertical bars 512 extend to the other side to form the low vertical bars 511, and the high vertical bars 512 themselves are connected to each other while the low vertical bars 511 themselves are not connected to each other.

As described above, as shown in FIG16 , similar first inner stirrups 510 ′ and second inner stirrups 520 ′ can be arranged along the first direction D1 and the second direction D2, respectively, and placed in the first outer stirrup opening OP1 defined by the first outer stirrups 410 and the second outer stirrup opening OP2 defined by the second outer stirrups 420. According to some embodiments, the first inner stirrups 510 ′ and the second inner stirrups 520 ′ can be arranged according to the expected strength design of the beam structure. For example, the first inner stirrups 510 ′ and the second inner stirrups 520 ′ can be arranged in correspondence with the easily deformed corner molding area K1, or more first inner stirrups 510 ′ and second inner stirrups 520 ′ can be arranged in correspondence with the easily deformed corner molding area K1, while fewer first inner stirrups 510 ′ and second inner stirrups 520 ′ can be arranged in the non-corner molding area K2. However, as previously mentioned, the positions of the internal stirrups and the configuration of the internal stirrups according to the various embodiments of the present invention are not limited to the specific embodiments shown here, and various variations or modifications may be made according to requirements and designs. As mentioned above, these possible variations or modifications will not be further elaborated here.

Next, the reinforcement system structure completed by the internal stirrup placement step S50' in FIG. 16 can be further constructed according to a process similar to that described above with reference to FIG. 1 through FIG. 13 , and a beam module fixing step S104' can be additionally performed corresponding to the beam module fixing step S104. Specifically, referring to FIG. 17 and FIG. 18 , the first upper layer of internal stirrups 530' and the second upper layer of internal stirrups 540' corresponding to the first internal stirrups 510' and the second internal stirrups 520' shown in FIG. 15 and FIG. 16 can be installed in this beam module fixing step S104'. The first upper layer inner stirrups 530' and the second upper layer inner stirrups 540' can be similar in configuration to the first inner stirrups 510' and the second inner stirrups 520' described above, but inverted and opposite directions. Specifically, each of the first upper layer inner stirrups 530' can have a set of short vertical bars 512' corresponding to one of the pair of first side spar upper layer main bars 310 and a set of long vertical bars 511' corresponding to the other of the pair of first side spar upper layer main bars 310. Similarly, each of the second upper inner stirrups 540' may have a set of short vertical bars 512' corresponding to one of the pair of second side spar upper main bars 320 and a set of long vertical bars 511' corresponding to the other of the pair of second side spar upper main bars 320. As described above, the set of long vertical bars 511' and the set of short vertical bars 512' extend into the first outer stirrup opening OP1 or the second outer stirrup opening OP2, and the set of long vertical bars 511' exceeds the set of short vertical bars 512' at the bottom and is connected to each other. Thus, when the first upper layer inner stirrups 530' and the second upper layer inner stirrups 540' are mounted on the first beam upper layer main reinforcement 910 or the second beam upper layer main reinforcement 920, respectively, the first upper layer inner stirrups 530' and the second upper layer inner stirrups 540' can complement the first inner stirrups 510' and the second inner stirrups 520'. That is, using the first inner stirrups 510' and the first upper layer inner stirrups 530' arranged along the first direction D1 as an example, the low vertical bar 511 will correspond to the long vertical bar 511' and be arranged near one side of the pair of first side spar upper layer main reinforcements 310, while the high vertical bar 512 will correspond to the short vertical bar 512' and be arranged near the other side of the pair of first side spar upper layer main reinforcements 310. In addition, the second inner stirrups 520' and the second upper inner stirrups 540' arranged along the second direction D2 can also be arranged similarly and will not be described in detail here.

Continuing from the above, as shown in FIG18 , after the first upper layer inner stirrups 530 ′ and the second upper layer inner stirrups 540 ′ are installed and matched with the first inner stirrups 510 ′ and the second inner stirrups 520 ′, the strength and stability of the overall beam structure can be enhanced.

Finally, after completing the construction process described above based on the construction process of FIG. 18 and continuing according to a process similar to that described in FIG. 1 through FIG. 13 , a complete beam-column structure, shown in FIG. 19 , is formed as a reinforcement system 2000. Furthermore, by utilizing the improved process of this exemplary embodiment, a reinforcement system comprising beam-column joints 250 and interconnected upper beam main bars can be completed while maintaining the desired reinforcement structure complexity, stability, and reliability.
