Description

Rapid assembly and disassembly structure of the skeleton of modular buildings

The present invention relates to a frame quick assembly and disassembly structure of a modular building, and in particular to a frame assembly and disassembly structure of a building with a simple structure, convenient assembly and stable positioning.

Traditional simple buildings with non-reinforced concrete structures are mostly made of strips of wood or metal pipes to form the main frame of the building; however, as wood is becoming increasingly difficult to obtain and is prone to mold and rot in Taiwan's humid and high temperature environment, the use of metal pipes to form the main frame of the building has become a more mainstream method.

The connection and assembly method between metal pipes of general building frames is relatively simple. The ends of two metal pipes to be connected (front and back) are overlapped, and then holes are drilled and bolts are inserted and screwed in to connect the two metal pipes. This assembly method will form a front and back step difference between the two metal pipes, which is not conducive to the subsequent wall assembly work on the building frame.

Alternatively, a metal connecting plate is attached to the ends of two metal pipes, or a sleeve is fitted over the ends of two metal pipes, and then bolts are passed through the metal connecting plate or sleeve and screwed into the metal pipes to connect and fix the two metal pipes. This structure requires the installation of a metal connecting plate or sleeve, which not only increases the cost, but also takes more time to assemble, which is not economical.

In the invention case No. 202321551 of the Republic of China, a building frame structure is disclosed, comprising: a plurality of first frames, a plurality of second frames, and a plurality of joints, wherein the plurality of first frames have two opposite first side panels, and the two first side panels are respectively provided with a first joint groove corresponding to the upper and lower directions of the first frames, and the first joint groove has an opening, two side walls, a bottom wall, and two clamping edges; and a groove is provided between one side edge of the two first side panels, and a second joint groove is provided inside the groove. ; The second frame has a plurality of frames and two clamping plates, the frame has a front plate, the front plate has second side plates on both sides, the two clamping plates are arranged at the rear center of the frame, the two clamping plates are respectively provided with at least one long strip through hole, and a third joining groove is arranged in front of the frame; the plurality of joints have a joining section and a locking section, the joining section is a rectangular body, and the locking section is joined with the joining section; thereby forming a building frame structure that can be quickly assembled and disassembled and has assembly stability.

However, the above structure is not only extremely complex in overall design, resulting in high manufacturing costs, but also complicated in assembly method and requires bolts to penetrate and fix, which is not only not economical but also not conducive to construction site operations.

In view of the above-mentioned shortcomings of the connection and assembly structure of the conventional building metal frame, the inventor has studied ways to improve these shortcomings, and finally the present invention is produced.

The main purpose of the present invention is to provide a frame quick assembly and disassembly structure of a modular building, comprising: a first frame element, a second frame element and a positioning element; wherein the first frame element has adjacent joint surfaces and positioning surfaces, the joint surface is connected to a receiving space provided inside the first frame element through a joint hole, the edge of the joint hole is provided with a side extension groove, and the positioning surface is provided with at least one positioning hole connected to the receiving space corresponding to the position where the side extension groove enters; the second frame element is provided with a joint portion protruding in the axial direction or in the radial direction, and the joint portion is provided with a side extension protruding in the transverse direction. The coupling part can extend into the receiving space through the coupling hole and pivot with the extending direction as the rotation center, so that the coupling part and the coupling hole pivot from an extending position to a locking position; the positioning element can be inserted into the receiving space through the positioning hole in the above-mentioned locking position, and stop at the space of the receiving space corresponding to the side extension groove, so that the side extension part in the locking position cannot be reversed to the position corresponding to the extending position of the side extension groove, so as to prevent the first frame element and the second frame element from separating by themselves, thereby forming a skeleton assembly structure with a simple structure and easy to assemble and disassemble quickly.

Another object of the present invention is to provide a quick assembly and disassembly structure of the frame of a modular building, wherein the joint surface and the joint hole can be set in the middle section or end surface of the first frame element; when the joint surface and the joint hole are set in the middle section of the first frame element, the second frame element and the first frame element can form a T-shaped bifurcated structure after being combined, and when the joint surface and the joint hole are set on the end surface of the first frame element, the second frame element and the first frame element can form a straight extension structure after being combined. By changing this assembly and disassembly structure, the application requirements of different frame parts can be met at the same time to reduce the overall use cost.

Another object of the present invention is to provide a quick assembly and disassembly structure of the frame of a modular building, wherein at least one end surface of the positioning element is provided with a recess, and at least one holding portion that is easy to be hooked is convexly provided in the recess; after the positioning element is inserted into the positioning hole, a tool with a hook (or a finger) can be inserted into the recess and the holding portion can be hooked to pull the positioning element outward from the positioning hole, so as to facilitate the disassembly operation between the second frame element and the first frame element easily and quickly.

In order to make the above-mentioned purpose, effect and characteristics of the present invention more specifically understood, the following drawings are provided for explanation:

Please refer to Figures 1 to 3, it can be seen that the main components of the building frame A of the present invention include: a first frame element 1, a second frame element 2 and a positioning element 3; wherein the first frame element 1 can be a long strip or tubular structure, and has two adjacent joint surfaces 10 and a positioning surface 100 on the surface of the first frame element 1, and a connecting hole 12 connected to a receiving space 11 is provided on the joint surface 10, and at least one side extension groove 121 protruding outward is provided on the edge of the connecting hole 12, and at least one positioning hole 13 is provided on the positioning surface 100, and the positioning hole 13 is connected to the position in the receiving space 11 corresponding to the entry of the side extension groove 121.

In a feasible embodiment, the first frame element 1 may be provided with two side extension grooves 121 protruding in opposite directions at the edge of the coupling hole 12, and two positioning holes 13 are provided on the positioning surface 100, which are respectively connected to the positions of the two side extension grooves 121 corresponding to the receiving space 11.

The second frame element 2 may also be an elongated strip or tubular structure, on which a coupling portion 21 protruding outwardly axially or radially is provided, and at least one side extension portion 211 extending laterally is provided at the outer end portion of the coupling portion 21 (the end away from the second frame element 2).

In a feasible embodiment, the second frame element 2 is provided with two side extension portions 211 extending symmetrically in opposite directions on the joint portion 21, so that the joint portion 21 is substantially in a T-shaped structure.

The positioning element 3 is a long strip structure that can be inserted into the receiving space 11 from the positioning hole 13 according to its protruding direction, and the positioning element 3 has a cross-sectional structure that is adapted to the shape of the positioning hole 13, so that a close plug-in connection relationship can be formed between the positioning element 3 and the positioning hole 13, and in the plug-in connection state, at least a portion of the positioning element 3 can extend into the position corresponding to the receiving space 11 in the two side extension grooves 121; a holding device 30 is provided at one end of the positioning element 3 away from the insertion into the positioning hole 13, and the holding device 30 can be composed of at least one holding portion 32 that is easily hooked and protrudes from a recess 31 (as shown in FIG. 3, it can be at least one pin provided in the recess 31).

Please refer to Figures 4 and 5. It can be seen that when assembling the present invention, the coupling portion 21 and the side extension portion 211 of the second frame element 2 are first inserted into the receiving space 11 through the coupling hole 12 and the side extension groove 121 of the first frame element 1 to an insertion position (as shown in Figure 4); then the second frame element 2 is pivoted (90 degrees) to a locking position with the insertion direction as the axis, and then the positioning element 3 is inserted into the positioning hole 13; when it is located at the locking position, the side extension portion 211 is blocked by the peripheral edge of the coupling hole 12 where the side extension groove 121 is not provided, so that the coupling portion 21 cannot pass through the coupling hole 12 in the reverse direction. In addition, when the coupling hole 12 and the coupling portion 21 are at the above-mentioned locking position, the positioning element 3 is inserted into the positioning hole 13 and the receiving space 11, and the positioning element 3 can block the portion of the receiving space 11 corresponding to the side extension groove 121, so that the side extension portion 211 of the coupling portion 21 at the locking position cannot be reversely rotated to the above-mentioned extended position corresponding to the side extension groove 121 (as shown in FIG. 5), and the first frame element 1 and the second frame element 2 can be maintained in a fixed state that cannot rotate to be detachable by themselves, so as to avoid the possibility of accidental loosening.

Please refer to Figures 6 and 7, it can be seen that when the positioning element 3 of the present invention is inserted into the positioning hole 13 for positioning, the end surface of the positioning element 3 can be designed to be flush with the peripheral surface of the positioning hole 13, so that the overall assembly has a smooth appearance; when disassembling, first use a tool 4 (or a finger) with a hook (or other tool that can pull the positioning element 3) to extend into the recess 31 of the positioning element 3, and can hook or pull the holding portion 32 (as shown in Figure 6); then pull the positioning element 3 outward After all the positioning elements 3 inserted into the positioning hole 13 have been removed, the coupling portion 21 can be reversed from the locking position to the inserted position relative to the coupling hole 12, so that the side extension portion 211 is rotated to a position corresponding to the side extension groove 121; and then the coupling portion 21 and the side extension portion 211 are respectively pulled out of the receiving space 11 through the coupling hole 12 and the side extension groove 121, so that the second frame element 2 can be detached from the first frame element 1.

Although, in the above structure of the present embodiment, the joint surface 10, the coupling hole 12 and the side extension groove 121 are arranged in the middle section of the first frame element 1, so that the second frame element 2 can form a (T-shaped) bifurcated assembly structure after being combined with the first frame element 1; however, in actual application, the joint surface 10, the coupling hole 12 and the side extension groove 121 can also be arranged on the end surface of the first frame element 1, so that the second frame element 2 can form an extended assembly structure with an increased length after being combined with the first frame element 1.

In summary, the skeleton quick assembly and disassembly structure of the modular building of the present invention can achieve the effects of simple structure, convenient assembly and stable positioning, and is indeed a novel and progressive invention, and an invention patent application is filed in accordance with the law; however, the above description is only for the better embodiment of the present invention, and all changes, modifications, alterations or equivalent replacements extended from the technical means and scope of the present invention should also fall within the scope of the patent application of the present invention.
