Description

Technical Field

[0001] This utility model relates to the field of prefabricated mobile building technology, and more specifically, to a column module for a prefabricated mobile building. Background Technology

[0002] Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Column modules are used when erecting the building's framework.

[0003] A search revealed a utility model patent with publication number CN220978798U, which discloses a column module for prefabricated buildings. The module includes a module structure and a quick-connect structure. The quick-connect structure allows for quick connection between the left and right modules. In use, a plate from another module is inserted into a mounting plate, aligning the limiting holes on the plate and the mounting plate. A limiting rod is then inserted into the aligned limiting holes to secure the module. The top plate of the other module is then inserted into a slot and pushed inwards to retract a fixing block into a groove. The plate is then fully inserted into the slot until the top plate is inserted into the top plate groove. A spring returns, pushing the fixing block upwards to secure the plate in the slot, completing the connection. This achieves a quick and stable connection between the upper and lower modules and the left and right modules, improving connection stability and work efficiency. However, the aforementioned patent has the following shortcomings: the column module for upper and lower connection is horizontally fixed using springs and fixing blocks, resulting in poor stability. Furthermore, when horizontally connecting modules, only the limiting rod provides fixation and load-bearing capacity, affecting the overall connection strength of the mobile building. Therefore, we propose a column module for prefabricated mobile buildings. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a column module for prefabricated mobile buildings.

[0005] To solve the above problems, the present invention adopts the following technical solution: a column module for a prefabricated mobile building, comprising two prefabricated columns and a prefabricated crossbeam, wherein a connecting mechanism is provided between the prefabricated columns and the prefabricated crossbeam, wherein each prefabricated column has a lower insertion groove at its bottom, and each prefabricated column has four side mounting grooves on its side at its bottom end, wherein each of the four side mounting grooves has multiple first mounting holes in its inner cavity, wherein each prefabricated column has an upper insertion block at its top, wherein each upper insertion block has multiple first screw holes on its side, wherein the upper insertion block at the top of one prefabricated column is movably fitted into the lower insertion groove at the bottom of another prefabricated column, and a first bolt is fitted into the first mounting hole on the side of the other prefabricated column, wherein the end of the first bolt is threaded into the inner cavity of the first screw hole.

[0006] As a preferred embodiment of this utility model, the connecting mechanism includes overlapping blocks disposed at both ends of the assembly crossbeam and multiple overlapping grooves and multiple fixing grooves disposed on the top side of the assembly column. Multiple second mounting holes are provided on both sides of the inner cavity of the overlapping groove. Multiple second screw holes are provided on the overlapping block. The end of the overlapping block is movably sleeved into the inner cavity of the overlapping groove. A second bolt is sleeved in the inner cavity of the second mounting hole, and the second bolt is threaded into the inner cavity of the second screw hole.

[0007] As a preferred embodiment of this utility model, the external size of the upper insertion block is equal to the internal size of the lower insertion slot.

[0008] In a preferred embodiment of this utility model, the size of the inner cavity of the overlapping groove is equal to the size of the outer shape of the overlapping block.

[0009] As a preferred embodiment of this utility model, the inner diameter of the first mounting hole is equal to the outer diameter of the first bolt.

[0010] In a preferred embodiment of this utility model, the inner diameter of the second mounting hole is equal to the outer diameter of the second bolt.

[0011] Compared with the prior art, the advantages of this utility model are: (1) In this utility model, when the upper and lower assembly columns are connected, the upper insertion block at the top of the lower assembly column is inserted into the lower insertion groove at the bottom of the upper assembly column, and the first bolt is inserted into the first mounting hole. The two assembly columns are connected by the cooperation of the first mounting hole, the first screw hole and the first bolt. The stability of the connection between the two assembly columns is ensured by the fit between the side of the upper insertion block and the inner wall of the lower insertion groove, which solves the problem of poor stability when the connection is fixed by the spring.

[0012] (2) In this utility model, when the assembly column and the assembly beam are connected, the overlapping block at the end of the assembly beam is inserted into the overlapping groove at the top side of the assembly column. The assembly column and the assembly beam are connected by the cooperation of the second bolt, the second mounting hole and the second screw hole. At the same time, the bottom surface of the inner cavity of the overlapping groove supports the overlapping block at the end of the assembly beam, ensuring the support strength of the assembly column for the assembly beam, thereby ensuring the load-bearing capacity of the assembly beam and avoiding the need to rely entirely on the limit rod for load bearing.

[0022] As shown in Figures 1 to 4, a column module for a prefabricated mobile building includes two prefabricated columns 1 and a prefabricated crossbeam 2. A connecting mechanism 9 is provided between the prefabricated columns 1 and the prefabricated crossbeam 2. Each prefabricated column 1 has a lower insertion groove 3 at its bottom and four side mounting grooves 4 on the side of its bottom end. Each of the four side mounting grooves 4 has multiple first mounting holes 5 in its inner cavity. Each prefabricated column 1 has an upper insertion block 6 at its top. The side of the upper insertion block 6 has multiple first screw holes 7. The upper insertion block 6 at the top of one prefabricated column 1 is movably fitted into the lower insertion groove 3 at the bottom of the other prefabricated column 1. A first bolt 8 is fitted into the first mounting hole 5 on the side of the other prefabricated column 1. The end thread is installed into the inner cavity of the first screw hole 7. The height of the inner cavity of the lower insertion groove 3 is equal to the height of the upper insertion block 6, so as to ensure that when the two assembly columns 1 are inserted one above the other, the bottom surface of the previous assembly column 1 fits against the top surface of the next assembly column 1. Example 2

[0023] Based on Embodiment 1, as shown in Figures 1 to 5, the connecting mechanism 9 includes overlapping blocks 12 disposed at both ends of the assembly beam 2 and multiple overlapping grooves 10 and multiple fixing grooves 11 disposed on the top side of the assembly column 1. Multiple second mounting holes 13 are provided on both sides of the inner cavity of the overlapping groove 10. Multiple second screw holes 14 are provided on the overlapping block 12. The end of the overlapping block 12 is movably sleeved into the inner cavity of the overlapping groove 10. The inner cavity of the second mounting hole 13 is fitted with a second bolt 15, and the second bolt 15 is threaded into the inner cavity of the second screw hole 14. Example 3

[0024] Based on Embodiments 1 and 2, as shown in Figures 2 to 5, the outer size of the upper insertion block 6 is equal to the inner size of the lower insertion groove 3, ensuring the stability of the upper insertion block 6 when inserted into the inner cavity of the lower insertion groove 3, and ensuring the stability of the two assembly columns 1 when inserted vertically. The inner size of the overlapping groove 10 is equal to the outer size of the overlapping block 12, ensuring the stability of the overlapping block 12 when inserted into the inner cavity of the overlapping groove 10. At the same time, the bottom of the inner cavity of the overlapping groove 10 supports the overlapping block 12 and the assembly beam 2. The inner diameter of the first mounting hole 5 is equal to the outer diameter of the first bolt 8, ensuring the stability of the first bolt 8 when inserted into the inner cavity of the first mounting hole 5. The inner diameter of the second mounting hole 13 is equal to the outer diameter of the second bolt 15, ensuring the stability of the second bolt 15 when inserted into the inner cavity of the second mounting hole 13.

[0025] It should be noted that this utility model is a column module for a prefabricated mobile building. When the prefabricated beam 2 is installed on the prefabricated column 1, the overlapping block 12 at the end of the prefabricated beam 2 is inserted into the overlapping groove 10 on the top side of the prefabricated column 1, so that the second mounting hole 13 and the second screw hole 14 are concentrically arranged. At this time, the second bolt 15 is inserted from the second mounting hole 13, so that the second bolt 15 is threaded into the inner cavity of the second screw hole 14 to fix the prefabricated column 1 and the overlapping block 12, thereby fixing the prefabricated column 1 and the prefabricated beam 2. In addition, the bottom surface of the inner cavity of the overlapping groove 10 supports the overlapping block 12 at the end of the prefabricated beam 2, ensuring the support strength of the prefabricated column 1 on the prefabricated beam 2, and thus ensuring the load-bearing capacity of the prefabricated beam 2.

[0026] When the two assembly columns 1 are connected vertically, the upper assembly column 1 is placed on the lower assembly column 1, and the upper insertion block 6 at the top of the lower assembly column 1 is inserted into the lower insertion groove 3 at the bottom of the upper assembly column 1. The first mounting hole 5 on the side of the assembly column 1 is connected to the first screw hole 7 on the side of the upper insertion block 6. The first bolt 8 is inserted into the first mounting hole 5, and the end of the first bolt 8 is threaded into the inner cavity of the first screw hole 7, thereby connecting the two assembly columns 1. At the same time, the lateral connection strength between the two assembly columns 1 is strengthened by the fit between the side of the upper insertion block 6 and the inner wall of the lower insertion groove 3.
