AI Technical Summary
In box-type modular buildings, the force transmission effect between the upper box-type module and the lower box-type module is difficult to ensure. The main reason is that the contact surface is not parallel, resulting in inaccurate position of the force transmission point, which reduces the load-bearing capacity of the beam body.
Accumulation space is set between the lower box module and the upper box module, and a force transmission component is set at intervals in the accumulating space, including a support member and a tightening block. The deformation force of the upper module is transmitted to the lower module through the support member and tightening block. The upper module is fixedly installed with multiple sets of connectors, and the support plate is fixed by positioning columns and plug welding to enhance the connection strength.
It improves the force transmission effect when stacking box modules, ensures accurate force transmission points, enhances the load-bearing capacity of the beam body, and reduces the deformation probability at the connection.

Description
Technical Field
[0001] This application relates to the technical field of modular buildings, and particularly to a force transmission structure for vertical stacking of box modules. Background Art
[0002] Modular building is a new building structure system. In this system, each room is used as a module unit, which is prefabricated in a factory, transported to the site after completion, and assembled into an integral building through a reliable connection method. Box modular building belongs to a type of prefabricated building, which refers to an assembled building form in which container modules used as transportation carriers are combined into houses at the construction site.
[0003] At present, large-span box modular buildings are composed of single-layer box modules stacked vertically. The upper box module and the lower box module are mainly connected and fixed through multiple groups of connecting pieces arranged on the box module, so as to fix the upper box module on the lower box module, thereby improving the load-bearing capacity of the box module beam.
[0004] During the construction process, the upper box module is directly placed on the lower box module. However, since it is difficult to ensure that the top surface of the lower box template and the bottom of the upper box template are completely parallel, it is difficult to ensure whether the force transmission points between the upper box module and the lower box module are located on the load-bearing beam of the box module, ultimately reducing the force transmission effect between the box modules. Summary of the Utility Model
[0005] In order to improve the force transmission effect when box modules are stacked, this application provides a force transmission structure for vertical stacking of box modules.
[0006] The force transmission structure for vertical stacking of box modules provided by this application adopts the following technical solutions:
[0007] A force transmission structure for vertical stacking of box modules includes a lower box module and an upper box module. The upper box module is stacked on the lower box module through multiple groups of connecting pieces. A receiving space is provided between the top of the lower box module and the bottom of the upper box module. Multiple groups of force transmission components are arranged at intervals in the receiving space. The force transmission components include:
[0008] A support member, which is arranged on the lower box module;
[0009] A pressing block, which is arranged on the upper box module and presses on the support member to transmit the acting force of the upper box module to the lower box module.
[0010] By adopting the above technical solution, the support member is fixedly installed on the lower box module, and then the upper box module is placed on the lower box module, so that the abutting block on the upper box module is in contact with the support member. The upper box module is fixedly installed on the lower box module through multiple groups of connecting members. When the upper box module deforms, the acting force is transmitted to the lower box module through the abutting block and the support plate, so as to improve the force transmission effect when the box modules are stacked.
[0011] Further, a top beam for supporting the top of the lower box module is provided on the lower box module, the support member is arranged on the top beam, and multiple groups of positioning holes are spaced apart on the top beam. The support member includes:
[0012] A support plate, which is abutted and arranged on the lower box module;
[0013] Positioning columns, multiple groups of the positioning columns are spaced apart on the support plate and are inserted into the positioning holes.
[0014] By adopting the above technical solution, during installation, the positioning columns are inserted into the positioning holes on the top beam to position the support plate, so that the support plate is fixedly installed at a specified position on the box body, which is convenient for cooperating with the abutting plate.
[0015] Further, multiple groups of round holes are spaced apart on the support plate, and the positioning columns pass through the round holes and are plug welded on the support plate.
[0016] By adopting the above technical solution, the positioning columns pass through the round holes and are plug welded on the support plate, so as to improve the connection strength between the positioning columns and the support plate.
[0017] Further, there are two groups of round holes on the support plate, and the two groups of round holes are arranged at the diagonal positions of the support plate.
[0018] By adopting the above technical solution, while reducing the number of positioning holes opened on the top beam, the fixing effect on the support plate is ensured.
[0019] Further, a bottom beam is provided on the upper box module, the abutting block is welded to the bottom of the bottom beam, and the deformation acting force of the bottom beam is transmitted to the top beam of the lower box module through the support plate.
[0020] By adopting the above technical solution, the position of the abutting block changes with the deformation of the bottom beam, so that when the bottom beam of the upper box module deforms, the acting force is transmitted to the support member through the abutting block.
[0021] Further, the top beam is made of I-beam, and stiffening plates for supporting between the two end faces of the I-beam are arranged on the top beam. The stiffening plates are located at the middle position of the support plate and are convenient for supporting the bottom of the support plate.
[0022] By adopting the above technical solution, multiple groups of force transmission components are installed on the top beam of the lower box module at intervals, so that the acting force of the upper box module on the lower box module is mainly concentrated at multiple groups of force transmission components. The top beam made of I-beam is supported by the stiffening plate, thereby improving the supporting effect of the top beam.
[0023] Further, a connecting steel plate is arranged between multiple groups of the abutting blocks. The connecting steel plate passes through multiple groups of abutting blocks in sequence and is welded on the abutting blocks.
[0024] By adopting the above technical solution, when the bottom beam at one place of the upper box module is deformed, the acting force of the upper box module on the abutting plate is distributed to multiple groups of abutting plates through the connecting steel plate, and then acts on the top beam of the lower box module through multiple groups of supporting plates, thereby improving the force transmission effect when the box modules are stacked.
[0025] Further, the two positioning columns on the supporting plate are respectively located on both sides of the middle cross beam of the I-beam top beam, and the two positioning columns are located on the opposite sides of the stiffening plate.
[0026] By adopting the above technical solution, the two positioning columns are respectively located on both sides of the middle cross beam of the I-beam top beam, and at the same time, the two positioning columns are located on the opposite sides of the stiffening plate, thereby improving the supporting and fixing effect between the top beam and the supporting plate and reducing the probability of deformation at the connection between the top beam and the supporting plate.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] 1. By inserting the positioning column into the positioning hole and making the supporting plate abut against the top beam of the lower box module, and then placing the upper box module on the lower box module, the abutting block welded on the bottom beam of the upper box module is in contact with the supporting plate. The locking screw is sequentially passed through the lower column, the core plate and the upper column, and the two ends of the locking screw are locked by the locking nut, so that the upper box module is fixedly installed on the lower box module. When the upper box module is deformed, the acting force is transmitted to the lower box module through the abutting block and the supporting plate, so as to improve the force transmission effect when the box modules are stacked.
[0029] 2. When the bottom beam at one place of the upper box module is deformed, the acting force of the upper box module on the abutting plate is distributed to multiple groups of abutting plates through the connecting steel plate, and then acts on the top beam of the lower box module through multiple groups of supporting plates, thereby improving the force transmission effect when the box modules are stacked.

[0036] The following further elaborates on the present application Figures 1-5 with reference to the attached drawings.
[0037] The embodiment of the present application discloses a force transmission structure for vertical stacking between box-type modules.
[0038] Embodiment 1
[0039] Referring to Figure 1 and Figure 2 , a force transmission structure for vertical stacking between box-type modules includes a lower box-type module 1 and an upper box-type module 2. The upper box-type module 2 is stacked on the lower box-type module 1 through multiple groups of connecting pieces 3. An accommodating space 4 is provided between the top of the lower box-type module 1 and the bottom of the upper box-type module 2. Multiple groups of force transmission components 5 are arranged at intervals in the accommodating space 4.
[0040] Referring to Figure 1 and Figure 2 , a top beam 11 for enhancing the support strength of the top of the lower box-type module 1 is fixedly installed on the top of the lower box-type module 1. The upper box-type module 2 is stacked on the lower box-type module 1 through multiple groups of connecting pieces 3. A bottom beam 21 is fixedly installed at the bottom position of the upper box-type module 2 corresponding to the top beam 11. In this embodiment, the upper box-type module 2 is fixedly installed on the lower box-type module 1 through four groups of connecting pieces 3.
[0041] Referring to Figure 1 and Figure 2, the connecting member 3 is used for connecting the columns. After the upper box module 2 is installed on the lower box module 1, it is fixedly connected through the connecting member 3, and a accommodating space 4 is formed between the top of the lower box module 1 and the bottom of the upper box module 2; a plurality of force transmission components 5 are arranged in the accommodating space 4 to transmit the force generated by the deformation of the bottom of the upper box module 2 to the lower box module 1. The force transmission component 5 includes a support member 6 and a pressing block 7. The support member 6 is arranged on the lower box module 1; the pressing block 7 is arranged on the upper box module 2, and the bottom of the pressing block 7 presses against the support member 6, and the pressing block 7 transmits the force generated by the deformation of the bottom of the upper box module 2 to the lower box module 1 through the support member 6; in this embodiment, there are 3 groups of force transmission components 5.
[0042] Referring to Figure 1 and Figure 3 , the support member 6 is arranged on the lower box module 1. A plurality of groups of positioning holes 111 are spaced apart on the top beam 11 of the lower box module 1. The support member 6 includes a support plate 61 and positioning columns 62. The support plate 61 is tightly pressed and installed on the bottom of the lower box module 1; the positioning columns 62 are spaced apart and installed on the support plate 61. There are a plurality of groups of positioning columns 62 on the support plate 61, and the positioning columns 62 correspond to the positioning holes 111 one by one. The positioning columns 62 are inserted and installed in the positioning holes 111, so as to fix the support plate 61 at a specified position on the top beam 11.
[0043] Referring to Figure 3 and Figure 4 , in order to improve the connection strength between the positioning column 62 and the support plate 61, a plurality of groups of round holes 611 are spaced apart on the support plate 61. The positioning column 62 passes through the round holes 611 and is inserted into the positioning holes 111. The positioning column 62 and the round holes 611 are welded and fixed on the support plate 61 by plug welding, so as to improve the connection strength between the support plate 61 and the plurality of positioning columns 62.
[0044] Referring to Figure 1 , Figure 3 and Figure 4 , since opening holes on the top beam 11 of the lower box module 1 is likely to reduce the support strength of the top beam 11, it is necessary to minimize the number of holes opened on the top beam 11. Therefore, two groups of round holes 611 are opened on the support plate 61, and the two groups of round holes 611 are opened at the diagonal positions of the support plate 61. The positioning columns 62 are fixedly installed on the round holes 611, and at the same time, the positions of the positioning columns 62 correspond to the positioning holes 111 one by one, so as to reduce the number of positioning holes 111 opened on the top beam 11 while ensuring the fixing effect on the support plate 61.
[0045] Referring to Figure 1 and Figure 3, the pressing block 7 is fixedly installed at the bottom of the bottom beam 21 of the upper box module 2 by welding, and the pressing block 7 is in contact with the upper surface of the support plate 61; when the bottom of the upper box module 2 does not deform, only the bottom of the pressing block 7 is in contact with the upper surface of the support plate 61 without mutual force; when the bottom beam 21 at the bottom of the upper box module 2 deforms, the bottom of the pressing block 7 presses against the upper surface of the support plate 61, so as to transfer the force generated by the deformation of the bottom beam 21 of the upper box module 2 to the support plate 61, and then transfer the force to the top beam 11 of the lower box module 1 through the support plate 61, so as to realize the force transfer between the upper box module 2 and the lower box module 1.
[0046] Refer to Figure 1 and Figure 3 , the top beam 11 of the lower box module 1 is made of I-beam material. Since the upper box module 2 transfers the acting force to the top beam 11 of the lower box module 1 through the pressing block 7 and the support member 6, in order to improve the support effect of the top beam 11 of the lower box module 1, a stiffening plate 112 for supporting between the two end faces of the I-beam is arranged on the top beam 11 of the lower box module 1. The stiffening plate 112 is located at the middle position of the support plate 61, and the position of the top beam 11 of the lower box module 1 where the support member 6 is located is strengthened through the stiffening plate 112, thereby improving the support effect of the top beam 11 of the lower box module 1.
[0047] Refer to Figure 1 , Figure 3 and Figure 4 , the two groups of positioning columns 62 are respectively located on both sides of the middle cross beam of the I-beam top beam 11, and at the same time, the two groups of positioning columns 62 are located on the opposite sides of the stiffening plate 112, thereby improving the support and fixing effect between the top beam 11 and the support plate 61, and reducing the probability of deformation at the connection between the top beam 11 and the support plate 61.
[0048] The working principle of Embodiment 1 of this application is as follows:
[0049] Insert the positioning column 62 into the positioning hole 111 and make the support plate 61 press against the top beam 11 of the lower box module 1, then place the upper box module 2 on the lower box module 1, so that the pressing block 7 welded on the bottom beam 21 of the upper box module 2 is in contact with the support plate 61, and sequentially pass the locking screw 34 through the lower column 31, the core plate 33 and the upper column 32 and lock the two ends of the locking screw 34 with locking nuts, so as to fixedly install the upper box module 2 on the lower box module 1. When the upper box module 2 deforms, the acting force is transferred to the lower box module 1 through the pressing block 7 and the support plate 61, so as to improve the force transfer effect when the box modules are stacked.
[0050] Embodiment 2
[0051] Refer toFigure 5 , the difference between this embodiment and Embodiment 1 is that multiple groups of abutting blocks 7 are installed on the bottom beam 21 of the upper box module 2 at intervals by welding. A connecting steel plate 8 is fixedly installed between multiple groups of abutting blocks 7. The connecting steel plate 8 passes through multiple groups of abutting blocks 7 in sequence and is installed on multiple groups of abutting blocks 7 by welding. As a result, the sides of multiple groups of connecting steel plates 8 away from the bottom beam 21 of the upper box module 2 are connected by the connecting steel plate 8, and the acting forces of multiple groups of abutting plates are distributed to multiple groups of support plates 61, improving the force transmission effect when the box modules are stacked.
[0052] The working principle of Embodiment 2 of this application is as follows:
[0053] When the bottom beam 21 of a certain part of the upper box module 2 deforms, the acting force of the upper box module 2 on the abutting plate is distributed to multiple groups of abutting plates through the connecting steel plate 8, and then acts on the top beam 11 of the lower box module 1 through multiple groups of support plates 61, improving the force transmission effect when the box modules are stacked.
[0054] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
