Description

Technical Field

[0001] This invention relates to the field of prefabricated building materials technology, specifically to a method for assembling prefabricated modular walls. Background Technology

[0002] Building materials, or simply building materials, are a general term for materials used in civil engineering and construction. They can be divided into structural materials, decorative materials, and certain special-purpose materials. Building walls are an important component of buildings, primarily serving to bear loads, enclose spaces, or divide them. Walls mainly include load-bearing walls and non-load-bearing walls. Walls that directly bear the load from the roof or floor above are called load-bearing walls; walls that do not bear the load from above are called non-load-bearing walls. Non-load-bearing walls include partition walls, infill walls, and curtain walls. Designing a reasonable wall scheme is an important task in building construction. However, most prefabricated walls used in construction currently on the market still have certain defects, such as…

[0003] For example, Chinese Patent Publication No. CN109779032A discloses a prefabricated wall structure, a prefabricated house, and its construction method. This includes a light steel frame, with an exterior wall panel on one side and an interior wall panel on the other. Vertical connecting slots are provided between the interior and exterior wall panels at both ends of the light steel frame. The light steel frame includes a side frame and a keel grid frame set within the side frame. An insulation layer is filled within the keel grid frame, and an air-tight layer is provided on both sides of the light steel frame. This invention is applicable to low-rise light steel prefabricated structure buildings, employing factory prefabrication and on-site assembly. The cooperation between the connecting slots and connecting steel pipes of the prefabricated wall structure improves the assembly speed of adjacent prefabricated walls, enhances the strength and sealing of the connection points, and facilitates insulation and waterproofing.

[0004] For example, Chinese Patent Publication No. CN108756023A discloses a prefabricated shear wall system and its assembly method, which includes: a connecting component and at least two prefabricated shear wall bodies; a uniformly distributed steel reinforcement cage ring is arranged in the middle position of the interior of each shear wall body; the shear wall body is made of recycled concrete; and the steel reinforcement cage rings in the two shear wall bodies are connected by the connecting component. This prefabricated shear wall system can solve the problems of complex construction process and unreliable seismic performance of traditional prefabricated shear walls, reduce construction costs, and promote the sustainable development of prefabricated building structures.

[0005] Another example is a prefabricated modular wall and its construction method, disclosed in Chinese Patent Publication No. CN112761302A. This includes a skeleton layer composed of two corrugated metal plates, structural layers on both sides of the skeleton layer, and a decorative layer fixed to the outside of the structural layers. The structural layers are fixed to both sides of the skeleton layer with tie bolts, and the decorative layer is fixed to the outside of the structural layers with screws, with staggered joints between the decorative layer and the structural layer. In this invention, the structural layer is assembled by fixing it to both sides of the skeleton layer with bolts, and then the decorative layer is fixed to the outside of the structural layer with screws. The structural layer is fixed horizontally, and the decorative layer is fixed vertically, which solves the problem of easy cracking on the surface of traditional prefabricated walls. In this invention, the flexible force of the skeleton layer is first partially offset by the rigid force of the structural layer, and then transmitted to the surface decorative layer. The flexible force continuously decreases, effectively preventing cracking on the outside of the wall.

[0006] However, the existing technical solutions mentioned above have the following drawbacks: Currently, the connection of prefabricated composite wall components involves the alignment accuracy of steel bars or bolts with holes, and the accuracy requirements are very high. Once misaligned, it is difficult to remedy the situation. At the same time, drilling installation has a certain impact on the stress of the prefabricated composite wall, which can easily lead to uneven stress and make it difficult to effectively connect load-bearing beams, walls and columns, thus resulting in certain defects in use. Therefore, we propose an assembly method for prefabricated composite walls to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an assembly method for prefabricated composite walls, in order to solve the problems mentioned in the background art, which currently involve the alignment accuracy of steel bars or bolts with holes in the connection of prefabricated composite structural components. The accuracy requirements are very high, and once misalignment occurs, it is difficult to remedy. At the same time, drilling installation has a certain impact on the stress of the prefabricated composite wall, which can easily lead to uneven stress and make it difficult to effectively connect load-bearing beams, walls and columns.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a method for assembling a prefabricated modular wall, comprising:

[0009] The column has a load-bearing beam fixedly connected to its upper end, and a connecting steel frame is connected to the outer surface of the column. A first supporting steel frame is welded and fixed to one end of the connecting steel frame near the center line of the load-bearing beam. A second supporting steel frame is fixedly connected to the end face of the first supporting steel frame near the center line of the load-bearing beam by bolts.

[0010] A limiting steel plate is welded and fixed to the end face of the second supporting steel frame near the center line of the load-bearing beam. A first U-shaped light steel is provided on the inner side of the limiting steel plate, and a first mounting wall is installed on the inner side of the first U-shaped light steel. A second mounting wall is provided on the front side of the first mounting wall, and an inner wall panel is filled between the first mounting wall and the second mounting wall.

[0011] The first fixing mechanism is installed below the load-bearing beam. The front end of the first fixing mechanism is connected to the second fixing mechanism, which plays a pressing role. A locking mechanism is connected between the first fixing mechanism and the second fixing mechanism.

[0012] A top plate is installed on the upper end of the second supporting steel frame, and a second U-shaped light steel is welded and fixed to the lower end face of the top plate;

[0013] The third U-shaped light steel is installed at the lower end of the first and second mounting walls.

[0014] Using the above technical solution, the connecting steel frame, the second supporting steel frame and the limiting steel plate serve to fix the first U-shaped light steel, and the top plate serves to support the second U-shaped light steel, thereby fixing the upper ends of the first and second mounting walls.

[0015] As a preferred technical solution of the present invention, the columns are symmetrically arranged about the center line of the load-bearing beam and play the role of supporting the load-bearing beam, and the outer surface of the load-bearing beam is provided with connecting steel frames at equal intervals from top to bottom.

[0016] By adopting the above technical solution, the connecting steel frame serves to connect the first supporting steel frame and the column, thereby fixing the first supporting steel frame and the second supporting steel frame.

[0017] As a preferred technical solution of the present invention, the inner wall panel includes a first sound insulation board, a first heat insulation board, a second sound insulation board and a second heat insulation board. The first heat insulation board is provided on the front surface of the first sound insulation board, the second sound insulation board is connected to the front end face of the first heat insulation board, and the second heat insulation board is connected to the front surface of the second sound insulation board.

[0018] By adopting the above technical solution, the performance of the wall is improved by setting up multiple layers of the first sound insulation board, the first thermal insulation board, the second sound insulation board, and the second thermal insulation board.

[0019] As a preferred technical solution of the present invention, the outer surfaces of the first sound insulation board, the first heat insulation board, the second sound insulation board and the second heat insulation board are all uniformly distributed with convex ridge structures, and the convex ridge structures between the first sound insulation board and the first heat insulation board, the first heat insulation board and the second sound insulation board, and the second sound insulation board and the second heat insulation board are all staggered.

[0020] By adopting the above technical solution, since the convex rib structures between the first sound insulation board and the first heat insulation board, the first heat insulation board and the second sound insulation board, and the second sound insulation board and the second heat insulation board are all staggered, the first sound insulation board and the first heat insulation board, the first heat insulation board and the second sound insulation board, and the second sound insulation board and the second heat insulation board are tightly attached, thereby improving the connection stability.

[0021] As a preferred technical solution of the present invention, the limiting steel plate is symmetrically arranged about the center line of the second supporting steel frame, and the second supporting steel frame is nested and connected to the first U-shaped light steel through the limiting steel plate;

[0022] By adopting the above technical solution, the second supporting steel frame and the limiting steel plate serve to fix the first U-shaped light steel, thereby limiting the first and second mounting walls.

[0023] As a preferred technical solution of the present invention, the first fixing mechanism includes a first fixing plate, a mounting block and a mounting groove, wherein the mounting block is fixedly disposed on the front end face of the first fixing plate and the mounting groove is formed on the front end face of the mounting block.

[0024] Using the above technical solution, the first fixing plate limits the first mounting wall, and the mounting groove serves to connect the second fixing mechanism.

[0025] As a preferred embodiment of the present invention, the second fixing mechanism includes a second fixing plate and a limiting connecting plate, wherein the limiting connecting plate is welded and fixed to the rear end face of the second fixing plate;

[0026] The above technical solution uses a limiting connecting plate to connect the first fixing mechanism.

[0027] As a preferred embodiment of the present invention, the limiting connecting plate is symmetrically arranged about the center line of the second fixed plate, and the limiting connecting plate and the mounting groove are slidably connected.

[0028] By adopting the above technical solution, the distance between the first fixing mechanism and the second fixing mechanism can be easily changed by sliding connection between the limiting connecting plate and the mounting groove, thereby fixing the first mounting wall and the second mounting wall.

[0029] As a preferred embodiment of the present invention, the locking mechanism includes a connecting rod and a connecting hole;

[0030] A connecting rod passes through the interior of the second fixed plate. The connecting rod is symmetrically arranged about the center line of the second fixed plate and is rotatably connected to the second fixed plate.

[0031] A connecting hole is provided on the front end face of the mounting block, and the mounting block is threadedly connected to the connecting rod through the connecting hole;

[0032] By adopting the above technical solution, the connecting rod is rotated within the connecting hole, which facilitates the movement of the second fixing mechanism backward, thereby pressing the first and second mounting walls together.

[0033] As a preferred technical solution of the present invention, the second U-shaped light steel and the third U-shaped light steel are respectively nested and connected to the upper and lower ends of the first mounting wall and the second mounting wall and play the role of limiting the first mounting wall and the second mounting wall.

[0034] The above technical solution uses the second and third U-shaped light steel bars to fix the upper and lower ends of the first and second mounting walls.

[0035] Compared with the prior art, the beneficial effects of the present invention are: the assembly method of the prefabricated composite wall is convenient for disassembling and installing the wall, and facilitates the effective connection of load-bearing beams, walls and columns. It solves the problem that most of the current prefabricated composite wall connection structures use steel bars or bolts to align with holes, which has a certain impact on the stress of the prefabricated composite wall and is prone to uneven stress.

[0036] 1. The device is equipped with a first fixing mechanism, a second fixing mechanism, and a connecting rod. An installation block is fixedly mounted on the front end face of the first fixing plate, and an installation groove is opened on the front end face of the installation block. At the same time, a limiting connecting plate is welded and fixed to the rear end face of the second fixing plate. The limiting connecting plate is symmetrically arranged about the center line of the second fixing plate, and the limiting connecting plate and the installation groove form a sliding connection. When fixing the first and second mounting walls, the connecting rod is rotated, causing the connecting rod to rotate in the connecting hole and drive the second fixing mechanism to move backward. This causes the rear end face of the second fixing plate to fit against the front end faces of the second and third U-shaped light steel bars, thereby fixing the first and second mounting walls and facilitating the disassembly and installation of the walls.

[0037] 2. A connecting steel frame, a second U-shaped light steel frame, and a third U-shaped light steel frame are provided. The first mounting wall, the inner wall panel, and the second mounting wall are installed sequentially through the second U-shaped light steel frame and the third U-shaped light steel frame. The second U-shaped light steel frame and the third U-shaped light steel frame are nested and connected to the upper and lower ends of the first mounting wall and the second mounting wall respectively, and play a role in limiting the first mounting wall and the second mounting wall. The connecting steel frame, the second supporting steel frame, and the limiting steel plate play a role in fixing the first U-shaped light steel frame, and in turn, the first U-shaped light steel frame plays a role in fixing and supporting the edge parts of the first mounting wall and the second mounting wall.

[0038] 3. The system includes a first supporting steel frame, a connecting steel frame, and a second supporting steel frame. The connecting steel frame is installed on the outside of the column, and the first and second supporting steel frames are then fixed together with bolts and nuts. Since the connecting steel frames are evenly spaced from top to bottom on the outer surface of the load-bearing beam, the column is subjected to more uniform stress. Furthermore, there is no need to drill holes in the column, which improves the column's strength. This solves the problem that most current prefabricated composite wall connection structures use steel bars or bolts to align with holes, which can affect the stress on the prefabricated composite wall and easily lead to uneven stress distribution.

The connecting rod 13 passes through the interior of the second fixing plate 1201. The connecting rod 13 is symmetrically arranged about the center line of the second fixing plate 1201. The second fixing plate 1201 is rotatably connected, and the connecting hole 17 is opened on the front end face of the mounting block 1102. The mounting block 1102 is threadedly connected to the connecting rod 13 through the connecting hole 17. The upper end of the second support steel frame 8 is equipped with a top plate 14, and the lower end face of the top plate 14 is welded and fixed with a second U-shaped light steel 15. The lower end of the first mounting wall 3 and the second mounting wall 4 is provided with a third U-shaped light steel 16. The top plate 14 serves to support the second U-shaped light steel 15, thereby fixing the upper end of the first mounting wall 3 and the second mounting wall 4.

[0050] When using this prefabricated modular wall assembly method, firstly, the first supporting steel frame 6 is installed on the outside of the column 1 via the connecting steel frame 7. Then, the first supporting steel frame 6 and the second supporting steel frame 8 are fixedly connected using bolts and nuts. Figure 1 and Figure 4As shown, because the connecting steel frame 7 is evenly spaced from top to bottom on the outer surface of the load-bearing beam 2, the force on the column 1 is more even, and there is no need to drill holes in the column 1, thus improving the strength of the column 1. Specifically, as shown... Figure 1 , Figure 3 and Figure 6 As shown, the first mounting wall 3, the inner wall panel 5, and the second mounting wall 4 are installed sequentially by the second U-shaped light steel 15 and the third U-shaped light steel 16. The second U-shaped light steel 15 and the third U-shaped light steel 16 are nested and connected to the upper and lower ends of the first mounting wall 3 and the second mounting wall 4 respectively, and play the role of limiting the first mounting wall 3 and the second mounting wall 4.

At the same time, the rear end face of the second fixing plate 1201 is welded and fixed with a limiting connecting plate 1202, and the limiting connecting plate 1202 is symmetrically arranged about the center line of the second fixing plate 1201. The limiting connecting plate 1202 and the installation groove 1103 form a sliding connection. When fixing the first mounting wall 3 and the second mounting wall 4, the connecting rod 13 is rotated, causing the connecting rod 13 to rotate in the connecting hole 17 and drive the second fixing mechanism 12 to move backward. This causes the rear end face of the second fixing plate 1201 to fit with the front end face of the second U-shaped light steel 15 and the third U-shaped light steel 16, thereby fixing the first mounting wall 3 and the second mounting wall 4.
