Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more particularly, relates to a prefabricated light steel building module. Background Art

[0002] A prefabricated building refers to a building assembled on-site with prefabricated components produced in a factory. The prefabricated construction mode adopts standardized design, factory production, and assembled construction, transferring a large amount of on-site work in the traditional construction method to the factory. It is a new type of building production method that can achieve energy conservation, land conservation, and convenience of building products. Light steel structure buildings belong to a type of prefabricated building and have the characteristics of light weight, expandability, and flexibility. Due to the reduction of building land, the lack of convenience in transporting large container buildings, and the increasing requirements for building quality and construction speed, the importance of its assemblability in the construction of prefabricated light steel buildings is increasingly emphasized by people and is also an important measurement index when people choose light steel buildings.

[0003] The existing prefabricated modular light steel buildings have some deficiencies: First, the building modules are separate boxes, and it is difficult to conveniently connect the surfaces of the modules to each other. Therefore, different building forms cannot be combined according to the requirements of use functions. Even if two are spliced together, there will be material waste and visual problems of double beams and double columns. In addition, current modular buildings such as space capsule houses and container houses have too many component classifications during production, which is not conducive to batch production. When transporting, the whole needs to be transported to the installation site by a truck, and it is impossible to achieve a large amount of rapid transportation of products. Summary of the Invention

[0004] In view of the above-mentioned prior art, the present invention provides a prefabricated light steel building module, which can realize the convenient production, transportation, on-site assembly, and use of the module.

[0005] To solve the above technical problems, the present invention proposes a prefabricated light steel building module, including: A bottom plate, side plates, and a top plate; the two sides of the bottom plate are respectively connected to the side plates, and the tops of the two side plates are connected to the top plate; The bottom plate, side plates, and top plate all include plate bodies. Inside the plate bodies, there are multiple main reinforcing ribs integrated with the plate bodies and several secondary reinforcing ribs intersecting with the main reinforcing ribs and integrated with the plate bodies. Reinforcing rib bolt holes are provided at both ends of each main reinforcing rib; The two sides of the top plate are bent downward and press on the upper edges of the side plates, and they are connected at the adjacent positions; the lower edges of the side plates are bent inward, the bottom plate is placed between the two side plates, and they are connected at the adjacent positions; When the bottom plate is connected to the two side plates and the top plate is connected to the two side plates, plug-in corner pieces are respectively arranged between the corresponding main reinforcing ribs. Corner piece bolt holes corresponding to the bolt holes of the reinforcing ribs are arranged on the two wing plates of the plug-in corner piece. After the two wing plates of the plug-in corner piece are inserted into the main reinforcing ribs at both ends, they are fixed by bolts, so that the bottom plate, the two side plates and the top plate are connected into a cylindrical structural module.

[0006] Preferably, the main reinforcing ribs and secondary reinforcing ribs on the outermost side of the plate surface are 25 - 35 cm away from the edge of the plate surface.

[0007] Preferably, waterproof rubber strip grooves are arranged at the joints of adjacent two plates, and waterproof rubber strips are filled in the grooves.

[0008] Preferably, bolt holes for hoisting are reserved on the top plate.

[0009] Preferably, when hoisting the top plate, bolts with rings are screwed into the reserved bolt holes on the top plate, and the bolt holes are sealed with plastic caps after hoisting is completed.

[0010] Preferably, bolt holes are provided at the edges of the top plate, side plates and bottom plate, and are staggered with the plug-in corner pieces and waterproof rubber strips.

[0011] Preferably, the waterproof rubber strip groove is arranged at the edge part of the joint of adjacent two plates.

[0012] Preferably, the two wing plates of the plug-in corner piece have the same shape, and the length of the wing plate is adapted to the distance between the main reinforcing ribs.

[0013] Preferably, the top plate, side plates and bottom plate are all made by bending process, and the thickness of the plate body is consistent.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Multiple module combination methods can be realized. The present invention can form various functional buildings through different combination methods of multiple modules horizontally, vertically and in the vertical direction, meeting the use requirements under different scenarios. Through the design of moving the reinforcing ribs on the plate body inward and inserting the plug-in corner pieces, the appearance of double beams and double columns at the module connection positions can be avoided, further saving materials and maintaining a beautiful appearance.

[0015] (2) Solve the problems of structural stress and waterproofing through structural design. The lightweight steel structure exoskeleton of the module (i.e., the plate body and the main / secondary reinforcing ribs) integrally solves the problems of structure, maintenance and waterproofing. The formed module is a cylindrical structure, and the top plate and side walls of the cylinder are the stress-bearing parts. The end plates do not bear force and are only enclosing structures. The top plate of the present invention is arranged on the upper parts of the two side plates, and the two side plates are arranged on both sides of the bottom plate. Combining with the setting of the waterproof grooves and rubber strips at the connection parts can achieve the waterproof effect.

[0016] (3) High degree of prefabrication, improving the convenience of factory production. The present invention simplifies the quantity and complexity of production parts. By using the bending process, a whole steel plate is bent into beams, columns, and plates required for modules. The components of the entire modular building only include four types: bottom plates, side plates, top plates, and plug-in corner pieces, reducing the time, labor, and materials for cutting and welding during the production process. The plates are plugged together on-site through corner pieces, reducing on-site wet operations and dependence on manual labor, shortening the construction period, and reducing the construction cost.

[0017] (4) Improving the convenience during transportation. The present invention disassembles the overall prefabricated modular building into upper and lower plates, side plates, and plug-in corner pieces, which can be quickly assembled on-site, stacked and transported in large quantities, saving time and space.

[0018] (5) The main stress positions of the structure are separated from the joint surfaces, and the connection methods of the modules are standardized, ensuring the stability of the structure and the convenience of production and assembly. The form of any joint contact surface for connecting and expanding with other modules of the module is unified, including the contact surface at the opening position of the end of the cylindrical structure.

[0021] The following further describes the present invention in conjunction with the drawings and specific embodiments, but the following embodiments are by no means any limitation to the present invention.

[0022] As Figure 1 shown, a prefabricated light steel building module proposed by the present invention includes a bottom plate 3, and is characterized in that: two side plates 2 are respectively connected to both sides of the bottom plate 3, and a top plate 1 is connected to the tops of the two side plates 2.

[0023] As Figure 2 shown, the bottom plate 3, side plates 2 and top plate 1 all include plate bodies 24 with the same structure. The inner surface of the plate body 24 is provided with multiple main reinforcing ribs 22 integrally formed with the plate body 24 and several secondary reinforcing ribs 23 intersecting with the multiple main reinforcing ribs 22 and also integrally formed with the plate body 24. As Figures 1 to 3 shown, the distance between the main reinforcing rib 22 and the secondary reinforcing rib 23 at the outermost side of the plate surface of the plate body 24 and the edge of the plate surface is 25 - 35 cm, and reinforcing rib bolt holes are provided at both ends of each main reinforcing rib 22. Figures 1 to 3 Also shown in [Figure] is the main bottom - plate reinforcing rib 31 and the secondary bottom - plate reinforcing rib 32 on the bottom plate 3, and the plate - body structure of the top plate 1 is the same.

[0024] Both sides of the top plate 1 are bent downward and press on the upper edge of the side plates 2, and adjacent plates are connected; the lower edge of the side plates 2 is bent inward, the bottom plate 3 is placed between the two side plates 2, and adjacent plates are connected; waterproof rubber - strip grooves 12 are provided at the joints of the two plates. As Figure 4 shown, the waterproof rubber - strip grooves 12 are filled with waterproof rubber strips, thereby preventing rainwater from seeping in through the horizontal joints.

[0025] When the bottom plate 3 is connected to the two side plates 2, inserting - angle members 21 are respectively provided between the main reinforcing ribs 22 corresponding to the bottom plate 3 and the two side plates 2 and between the main reinforcing ribs corresponding to the top plate 1 and the two side plates 2. A gap is left between the corner ends of the inserting - angle members 21 and the joints of the two plates (or the sharp corners are designed in a notch shape) to prevent the inserting - angle members 21 from interfering with the waterproof rubber strips in the waterproof rubber - strip grooves 12 at the joints of the two plates.

[0026] Angle - member bolt holes 212 corresponding to the positions of the reinforcing - rib bolt holes 211 are provided on both wing plates of the inserting - angle member 21. After inserting the two wing plates of the inserting - angle member 21 into the main reinforcing ribs 22 at both ends, taking the connection between the side plate 2 and the bottom plate 3 as shown in Figure 3 an example, one wing - plate end of the inserting - angle member 21 is inserted into the main reinforcing rib 22 of the side plate, and the other wing - plate end is inserted into the main bottom - plate reinforcing rib 31. Align the angle - member bolt holes 212 on the two wing plates of the inserting - angle member 21 with the main - reinforcing - rib bolt holes 211 on the main reinforcing rib 22 of the side plate and the main bottom - plate reinforcing rib 31 respectively, then insert bolts, and fix the inserting - angle member 21 to the main reinforcing rib 22 of the side plate and the main bottom - plate reinforcing rib 31 through the bolts. Similarly, fix the inserting - angle members 21 at various positions between the two side plates 2 and the bottom plate 3 and between the two side plates 2 and the top plate 1 to the main reinforcing ribs at both ends, thereby connecting the bottom plate 3, the two side plates 2 and the top plate 1 into a cylindrical - structure module, as Figure 1 shown.

[0027] In the present invention, the primary and secondary reinforcing ribs 22 and 23 on the plate body 24 are moved inward and connected with the plug-in corner pieces 21, so that the appearance of double beams and double columns at the module junction position can be avoided. Specifically, the connection between the top plate 1 and the side plate 2 and the connection between the side plate 2 and the bottom plate 3 are non-double-beam and double-column structures, which not only further saves materials but also maintains a beautiful appearance.

[0028] The building module of the present invention can be assembled into a house body, and only a top plate 1, a side plate 2 and a bottom plate 3 with integral structural primary / secondary reinforcement ribs, and plug-in corner pieces 21, sealing strips, a steel foundation and a pile foundation are required. During installation, the foundation and the bottom plate 3 are first installed, and the waterproof strip grooves 12 provided at the connection between the top plate 1 and the side plate 2, and the side plate 2 and the bottom plate 3 are filled with waterproof strips to prevent rainwater from seeping in from the horizontal seams. When connecting the bottom plate 3 and the two side plates 2, as described above, one end of a plurality of plug-in corner pieces 21 is respectively inserted into the main reinforcement rib 22 of the bottom plate 3, and the other end of the plug-in corner piece is inserted into the main reinforcement rib of the side plate 2, so that the middle bottom plate 3 is clamped by the inward bending structure of the lower edges of the two side plates 2, and the side plates 2 on both sides are fastened to the bottom plate 3 by bolts, and then the top plate 1 is hoisted, and the two sides of the top plate 1 are covered with side plates 2, and the top plate 1 is connected to the side plates 2 on both sides by plug-in corner pieces in the same way. In the present invention, the top plate 1 is provided with bolt holes for hoisting. When hoisting the top plate 1, bolts with rings are screwed into the bolt holes reserved on the top plate. After hoisting, the bolt holes are sealed with plastic caps.

[0029] In the present invention, the edges of the top plate 1, the side plate 2 and the bottom plate 3 are provided with bolt holes for connecting modules at positions staggered from the plug-in corner pieces 21 and the waterproof rubber strips, which are used to connect multiple building modules by bolts to form a building module system. The building modules provided by the present invention can form an extensible assembled light steel building module system, in which the modules can be connected and can be expanded in the horizontal, horizontal, vertical and vertical directions.

[0030] Although the present invention has been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can make many improvements and changes without departing from the purpose of the present invention, which are all within the protection of the present invention.
