Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of steel structure modular building, and particularly relates to a connecting structure of a building module and a stair module. BACKGROUND

[0002] The overhead layer refers to a part of the space of the bottom layer of a building being lifted, so that the foundation is separated from the ground. In this way, the steel can be effectively prevented from being damp, and the service life of the building is prolonged. This structure is commonly used in areas with long rainy seasons in the south, and is usually used as an equipment layer to connect pipelines and install equipment, so that workers can enter the overhead layer to check and maintain the equipment. In order to facilitate personnel access, an entrance stair is usually arranged on the overhead layer. Due to the large difference between the stair module and the steel structure modular building in overall quality and foundation embedding depth, the stair module is usually welded on the steel structure modular building in the prior art to improve the stability of the connection. However, this welding connection method has low installation efficiency, and is affected by uneven settlement, which may cause stress concentration at the connection part, thereby damaging the stair module. Another method is to directly connect the two together by bolts, which improves the installation efficiency, but due to the poor stability of the connection, wear and tear may occur after a long period of use, and noise problems may also occur. SUMMARY

[0006] Further, the grid plate comprises a plurality of grid bars; the edge beam comprises an edge beam body, a stiffener, a support plate and a fastener, the stiffener is arranged at the side end face of the edge beam body at intervals, and the support plate is arranged vertically at the top end of the stiffener; one end of the plurality of grid bars is arranged on the support plate, and the fastener is fastened to the grid bars and detachably connected to the support plate.

[0007] Furthermore, each of the stiffening plates has an independent support plate at its top.

[0027] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] This invention proposes a connection structure between a building module and a stair module, which is used to set up a stair module at the entrance of the building module, especially suitable for situations where the building module has a mezzanine. By setting up a platform module and an extension module, the standardized building module and the stair module form a stable connection structure, which not only facilitates installation but also has good reliability and durability. It can effectively avoid damage caused by uneven settlement and can adapt to the actual needs of different building environments.

[0029] like Figure 1 , Figure 2As shown, this embodiment of the invention proposes a connection structure between a building module and a stair module, including a building module 8, a stair module, a platform module, and an extension module. The platform module has a support structure, and the stair module and the connection module are detachably connected to the support structure. The extension module includes a grating plate 6, one end of which is inserted into the side beam 9 at the bottom of the entrance of the building module 8. In this application, the building module 8, the stair module, the platform module, and the extension module are all standardized prefabricated modules in the factory and assembled into an integral structure on site. The extension module and the platform module are used to connect the stair module and the building module 8 to form a passageway connecting the staircase and the entrance of the building module 8. The bottom end of the support structure is connected to the ground to provide support for the stair module, the platform module, and the extension module. The stair module and the building module 8 form two independent force systems through independent support structures. When uneven settlement occurs in the foundation, the settlement difference only affects the corresponding module and will not be transmitted to other modules through the structural connection, thereby avoiding staircase tilting, wall cracking, or overall structural instability caused by settlement difference. Meanwhile, the connection method of the extension module through the grid plate 6 and the side beam 9 at the bottom of the entrance of the building module 8 allows for a certain settlement difference. Compared with the method of directly connecting the stair module 10 to the side beam 9 with bolts, it effectively avoids wear caused by insufficient flatness of the connection surface between the stair and the side beam 9, and also improves the stability of the overall structure.

[0030] Furthermore, such as Figure 3 , Figure 4 , Figure 5 As shown in this embodiment, the extension module includes an end beam 3 and a connecting beam 2. One end of the end beam 3 is connected to the supporting structure, and the other end extends towards the side beam 9 to form a cantilever end. Both ends of the connecting beam 2 are connected to the cantilever end, and several horizontal members 7 are spaced apart between the side beam 9 and the end beam 3 to support the grating plate 6. The grating plate 6 directly bears the pedestrian load and transfers part of the load to the horizontal members 7. The horizontal members 7 further transfer the load to the end beam 3 and the connecting beam 2. The end beam 3 and the connecting beam 2 are connected to the supporting structure of the platform module to form an overall support force system. At the same time, one end of the grating plate 6 extends to the outside of the connecting beam 2 and connects to the side beam 9, which can transfer another part of the load to the side beam 9, making the entire grating plate 6 more evenly stressed and the connection more stable.

[0031] The aforementioned horizontal member 7 can be arranged parallel to the end beam 3, with both ends connected to the connecting beam 2 and the supporting structure respectively; it can also be arranged parallel to the connecting beam 2, with both ends connected to the end beam 3 respectively; or the horizontal member 7 includes a longitudinal support member and a transverse support member, which are parallel to the connecting beam 2 and the end beam 3 respectively, without any limitation; preferably, the horizontal member 7 is evenly arranged in the space enclosed by the end beam 3, the connecting beam 2 and the supporting structure.

[0032] In one specific embodiment, the horizontal member 7 is a square steel tube, with its two ends welded to the connecting beam 2 and the supporting structure or to the two end beams 3 respectively.

[0033] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown in this embodiment, the grating plate 6 includes multiple grating strips 601; the side beam 9 includes a side beam 9 body, stiffening plates 15, support plates 13, and fasteners 12. The stiffening plates 15 are spaced apart on the side end faces of the side beam 9 body, and the support plates 13 are vertically arranged on the top of the stiffening plates 15; one end of each grating strip 601 is attached to the support plate 13, and the fasteners 12 are fastened to the grating strips 601 and detachably connected to the support plate 13. The stiffening plates 15 are arranged on the side end faces of the side beam 9 body near the outer side and are perpendicular to the side end faces; the support plates 13 are vertically arranged on the top of the stiffening plates 15; the grating plate 6 is formed by a crisscrossing mesh structure of multiple grating strips 601. Generally, the grating strips 601 are made of flat steel and have characteristics such as high strength, lightweight, anti-slip and wear-resistant. The bottom surface of the grating strip 601 contacts the top surface of the support plate 13 and is stably fixed to the support plate 13 by the fastener 12, forming a contact surface connection. This facilitates installation, ensures a stable connection, and improves installation efficiency. Preferably, the grating strip 601 is spot-welded to the horizontal member 7 to further improve the overall integrity and stability of the structure.

[0034] It should be noted that, under normal circumstances, the top surface of the main body of the side beam 9 is used to support other upper structures of the building module 8 and is located at the edge of the building module 8; the stiffening plate 15 is set on the relatively outer end face of the main body of the side beam 9, and at least part of its width protrudes relative to the upper structure; the support plate 13 is set on the side of the stiffening plate 15 that protrudes from the upper structure. By reasonably setting the position of the stiffening plate 15, the thickness of the support plate 13 and the thickness of the grid plate 6, the top surface of the grid plate 6 can be flush with the entrance of the building module 8, so as to achieve the alignment and connection between the two.

[0035] In a specific embodiment, such as Figure 6 As shown, the stiffening plate 15 has a notch at one end away from the main body of the side beam 9. The notch is adapted to the width of the support plate 13, and the support plate 13 is welded to the notch.

[0036] In this embodiment, the number and spacing of stiffening plates 15 can be set according to actual needs, and the position of stiffening plate 15 can correspond to a grid strip 601; the support plate 13 can be one, which is arranged along the entire length of the stiffening plate 15, or it can be multiple, with each support plate 13 connecting multiple stiffening plates 15; preferably, each stiffening plate 15 has an independent support plate 13 at its top, so that the load can be distributed to the main structure through the stiffening plate 15, and local stress concentration can be reduced, avoiding cracking or deformation at the connection between the continuous support plate 13 and the stiffening plate 15.

[0037] Furthermore, in the embodiments of this application, such as Figure 7 As shown, the fastener 12 includes a limiting groove and connecting plates disposed on both sides of the limiting groove. The opening of the limiting groove faces the support plate 13 and is fastened to the grid strip 601. The connecting plates are connected to the support plate 13 by bolts 10. Bolt 10 holes are provided at corresponding positions on the connecting plates and the support plate 13. The shape of the limiting groove is adapted to the grid strip 601, so that when the fastener 12 is connected to the support plate 13 by bolts 10, the grid strip 601 can be fixed on the support plate 13, preventing the grid strip 601 from moving upward, downward, and to the sides, thereby limiting and fixing the grid strip 601.

[0038] Furthermore, in the above embodiment, the upper end face of the support plate 13 is provided with a buffer pad 11. The buffer pad 11 can increase the friction between the grid strip 601 and the fastener 12 connecting plate, avoid relative movement, and further improve the stability of the connection. On the other hand, it can also improve the tightness of the bolt 10 connection, prevent the bolt 10 from loosening due to vibration, and improve the reliability and durability of the structure.

[0039] Furthermore, in the embodiments of this application, such as Figure 1 , Figure 2 As shown, the supporting structure includes columns 1 and beams 16. The beams 16 are arranged between adjacent columns 1, and one end of the end beams 3 is connected to the columns 1. Specifically, there are at least four columns 1, each with a base plate 4 at its bottom. The base plate 4 has bolt holes 10 and is connected to the ground through the base bolts 10. The multiple columns 1 form a square or rectangle, and the beams 16 are arranged between two adjacent columns 1. The upper load of the beams 16, the load transmitted by the end beams 3, and the load transmitted by the stairs are all transmitted to the columns 1, and then to the ground through the columns 1.

[0040] Furthermore, in this embodiment of the application, a horizontal member 7 and a grid plate 6 are provided between the crossbeams 16; the structure and arrangement method of the horizontal member 7 and the grid plate 6 are consistent with those in the extension module, wherein the grid plate 6 can be the same grid plate 6 connected to the grid plate 6 in the extension module, or it can be an independently set grid plate 6.

[0041] In this embodiment, the stair module can be connected to the crossbeam 16 of the supporting structure, or it can be connected to both the crossbeam 16 and the column 1, with the two connected by bolts 10.

[0042] In the above embodiments, the position of the stair module can be set according to requirements. For example, the stair module can be set opposite to the extension module at both ends of the platform module, so that the extension module, platform module and stair module are connected in a straight line; the stair module can also be set opposite to the extension module at the adjacent ends of the platform module, so that the extension module, platform module and stair module are connected in an L-shape; or there can be two stair modules, which is not limited here.

[0043] Preferably, in the above embodiment, the top of the grating plate 6 is flush with the top surfaces of the crossbeam 16 and the end beam 3, and higher than the connecting beam 2. This arrangement allows the end beam 3 and the horizontal member 7, and the crossbeam 16 and the horizontal member 7, to form a groove structure, thereby limiting the position of the grating plate 6. Simultaneously, it allows the grating plate 6 to form a continuous and complete plane with the top of the end beam 3, the crossbeam 16, and the entrance of the building module 8, facilitating pedestrian passage.

[0044] Furthermore, in a preferred embodiment, the top of the column 1 is also provided with a canopy 17, which extends above the extension module, platform module, and staircase module. For example... Figure 1 , Figure 2 As shown, the extension module, platform module, and stair module are connected in an L-shape. There are five columns 1, which are respectively set at the connection between the extension module and the platform module, at the corner of the platform module, and on both sides of the stair module. The canopy 17 is set at the top of the columns 1 and can cover all the extension modules, platform modules, and part of the stair module.

[0045] The advantages and positive effects of this invention are:

[0046] (1) By setting up extension modules and platform modules to connect the stair module and the building module together, the stair module and the building module form two independent force systems through independent support structures, which can effectively avoid structural damage or instability caused by differential settlement.

[0047] (2) By setting the connection method of grid plate and edge beam, a certain settlement difference can be allowed, which effectively avoids wear caused by insufficient flatness of the connection surface when the stairs are directly connected to the edge beam, and improves the stability of the overall structure.

[0048] (3) By setting stiffening plates, support plates and fasteners, the grid strips can be stably fixed on the support plate, which is convenient to install, has a solid connection, improves installation efficiency, and has good stability and durability.

[0049] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the scope of the present invention should still fall within the patent coverage of the present invention.
