Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a prefabricated light steel building wall panel and its assembly and disassembly method. Background Technology

[0002] Light steel structure wall panels are characterized by being green and environmentally friendly, having good seismic performance, fast construction speed, and being recyclable. Cold-formed thin-walled steel can economically achieve a more reasonable cross-sectional shape, thereby obtaining a satisfactory strength-to-weight ratio. Therefore, in steel structure buildings, the rational use of cold-formed thin-walled steel can significantly reduce steel consumption. The use of cold-formed thin-walled steel in buildings is of great significance for saving resources and energy, reducing environmental pollution, and promoting sustainable social development.

[0003] Existing cold-formed thin-walled building technology includes the following methods for constructing composite walls using cold-formed thin-walled steel profiles: 1. The structural frame is sealed with panels on both sides, and the middle is filled with rock wool or glass wool, forming a "hollow wall"; 2. The structural frame is sealed on one side with a plate, and lightweight thermal insulation mortar is sprayed on the construction site; or the structural frame is sealed on both sides with a plate, and lightweight thermal insulation mortar is poured on the construction site to form a "solid wall". 3. The construction method of sealing one side of the structural frame with polyurethane foam spraying on site. The above approach mainly relies on the light steel keel frame for load-bearing and structural strength, with almost no application of the strength of cold-formed thin-walled steel. There is only a modular design of wall panel units without matching connectors. Not only can they not be connected and installed together, but they also cannot be customized according to the size of the site construction. When different sizes of modules are needed on site, a wall panel unit can only be dismantled and then cut, which is not only time-consuming and labor-intensive, but also results in an incomplete wall panel unit structure with poor strength. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a prefabricated light steel building wall panel and its assembly and disassembly method. The purpose is to solve the technical problems mentioned in the background art, such as the almost non-existent strength application of cold-formed thin-walled panels; the lack of matching connectors, making them unable to be connected and installed; and the time-consuming and labor-intensive process of cutting wall panel units on-site, resulting in incomplete wall panel unit structures and poor strength.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated light steel building wall panel, comprising multiple cold-formed thin-walled panels, with upper keels at the upper ends of the multiple cold-formed thin-walled panels, lower keels at the lower ends of the multiple cold-formed thin-walled panels, and lightweight polymer aggregate concrete filling blocks between the multiple cold-formed thin-walled panels. One side of each of the multiple cold-formed thin-walled panels is located on one side of a straight wall connecting column, and the other side of each of the multiple cold-formed thin-walled panels is located on one side of a corner connecting column.

[0006] Furthermore, the cold-formed thin-walled sealing plate has multiple trapezoidal reinforcing bending grooves in the middle, and a grouting port is opened on one side of the upper end of the multiple trapezoidal reinforcing bending grooves.

[0007] Furthermore, both the upper keel and the lower keel include a keel base plate. The two sides of the keel base plate are respectively provided with keel edging. The middle part of the multiple keel edgings is provided with multiple trapezoidal bent edges. A sealing plate limiting block is provided between the multiple trapezoidal bent edges and the keel edgings. Keel positioning holes are respectively opened in the middle of the multiple trapezoidal bent edges and the middle part of the keel base plate.

[0008] Furthermore, a grouting avoidance opening is provided on one side of the trapezoidal bent edge.

[0009] Furthermore, the upper keel and the lower keel are arranged symmetrically, one above the other.

[0010] Furthermore, multiple sealing plate insertion slots are respectively opened on both sides of the straight wall connecting column.

[0011] Furthermore, the middle portion of each of the multiple sealing plate insertion slots is provided with a direct anti-slip toothed strip, and the upper and lower ends of each of the multiple sealing plate insertion slots are respectively provided with bevels.

[0012] Furthermore, one side of the corner connecting post is provided with multiple sealing plate insertion slots, and the other side of the corner connecting post is provided with a right-angle connecting block. One side of the right-angle connecting block is provided with multiple connecting ports, and the other side of the right-angle connecting block is provided with multiple connecting hooks.

[0013] Furthermore, a method for assembling and disassembling prefabricated light steel building wall panels includes the following steps: S1. Insert the lower ends of the multiple cold-formed thin-walled end panels into the inner sides of the lower keel and fix them with self-tapping screws. Insert the upper ends of the multiple cold-formed thin-walled end panels into the inner sides of the upper keel and fix them with self-tapping screws to obtain a single wall panel. S2. Install the lower keel of a single wall panel obtained in S1 on the ground by passing expansion bolts through the keel positioning holes, and then install the upper keel on the top surface by passing expansion bolts through the keel positioning holes, thus completing the assembly of the first wall panel; S3. The first wall panel installed in S2 is connected to the second single wall panel by inserting it into the straight wall connecting column. Repeat the operation in S2 until the remaining distance is less than the length of a cold-formed thin-walled sealing plate. S4. According to the required size for the remaining distance, cut multiple cold-formed thin-walled panels, the upper keel and the lower keel on site, and then perform the operation in S1 to obtain a single wall panel that meets the size of the remaining distance. S5. Connect one side of the single wall piece that meets the remaining distance dimensions obtained in S4 to one side of the last single wall piece installed in S3 through a straight wall connecting column, thus completing the installation of the straight wall; S6. Insert the corner connecting posts on both sides of the straight wall respectively, and connect another right-angle connecting block through multiple connecting ports or multiple connecting hooks on the right-angle connecting block. Then repeat the operations of S3, S4 and S5 to complete the process. S7. Lightweight polymer aggregate concrete grout is injected between the multiple cold-formed thin-walled sealing plates through each of the grouting ports, and solidifies to form the lightweight polymer aggregate concrete filling block after filling.

[0014] Furthermore, when cutting multiple cold-formed thin-walled end plates on-site in S4, the cutting must be done on a plane other than the inclined surfaces on both sides of the multiple trapezoidal reinforcing bending grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Multiple trapezoidal reinforcing bending grooves on the cold-formed thin-walled sealing plate replace the longitudinal support provided by the longitudinal keel in the existing technology, thereby reducing the material used for the keel and lowering costs. Straight walls are formed by interlocking the sealing plate with the straight wall connecting columns, and corner walls are formed by interlocking the corner connecting columns, further enhancing modularity and making assembly quick and convenient. The interlocking of the cut sealing plate with the straight wall connecting columns and corner connecting columns ensures the integrity of the assembly after cutting. Lightweight polymer aggregate concrete is filled by grouting, which strengthens the connection strength of the various components after assembly and also ensures the thermal insulation, heat insulation, and sound insulation effects of the wall.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please refer to the following examples. Figure 1-3A prefabricated light steel building wall panel includes multiple cold-formed thin-walled panels 1. The upper ends of the multiple cold-formed thin-walled panels 1 are provided with upper keels 2, the lower ends of the multiple cold-formed thin-walled panels 1 are provided with lower keels 3, and lightweight polymer aggregate concrete filling blocks 4 are provided between the multiple cold-formed thin-walled panels 1. One side of each of the multiple cold-formed thin-walled panels 1 is provided on one side of a straight wall connecting column 5, and the other side of each of the multiple cold-formed thin-walled panels 1 is provided on one side of a corner connecting column 6.

[0022] Please refer to the following examples. Figure 4 The cold-formed thin-walled sealing plate 1 has multiple trapezoidal reinforcing bending grooves 11 in the middle, and a grouting port 12 is opened on one side of the upper end of the multiple trapezoidal reinforcing bending grooves 11. This design allows grouting of the assembled wall through the grouting port 12, filling it with lightweight polymer aggregate concrete.

[0023] Please refer to the following examples. Figure 5 Both the upper keel 2 and the lower keel 3 include a keel base plate 21. The keel base plate 21 has keel edging 22 on both sides. The middle part of the multiple keel edging 22 is provided with multiple trapezoidal bent edges 23. A sealing plate limiting block 24 is provided between the multiple trapezoidal bent edges 23 and the keel edging 22. The middle part of the multiple trapezoidal bent edges 23 and the middle part of the keel base plate 21 are respectively provided with keel positioning holes 25. A grouting avoidance opening 231 is provided on one side of the trapezoidal bent edges 23. This design limits the relative position of the two cold-formed thin-walled sealing plates 1 through the sealing plate limiting block 24, avoiding misalignment that could lead to grouting voids.

[0024] In this embodiment, the upper keel 2 and the lower keel 3 are arranged symmetrically, one above the other.

This design prevents the cold-bent thin-walled sealing plate 1 from slipping off through the direct anti-slip toothed strip 511, and facilitates the insertion of the cold-bent thin-walled sealing plate 1 through the upper and lower bevels 512.

[0026] Please refer to the following examples.

The right-angle connecting block 61 has multiple connecting ports 62 on one side and multiple connecting hooks 63 on the other side. This design allows multiple connecting hooks 63 on one corner connecting post 6 to be inserted and matched with multiple connecting ports 62 on another corner connecting post 6, thereby achieving right-angle docking through the right-angle connecting blocks 61 set at a 90° angle.

[0027] An example of an assembly and disassembly method for prefabricated light steel building wall panels is provided; please refer to this example carefully. Figure 9-12 This includes the following steps: S1.

S2. Install the lower keel 3 of a single wall panel obtained in S1 on the ground by passing expansion bolts through the keel positioning hole 25, and then install the upper keel 2 on the top surface by passing expansion bolts through the keel positioning hole 25, thus completing the assembly of the first wall panel; S3. The first wall panel installed in S2 is connected to the second single wall panel by inserting it through the straight wall connecting column 5. Repeat the operation in S2 until the remaining distance is less than the length of a cold-formed thin-walled sealing plate 1. S4. According to the required size for the remaining distance, cut multiple cold-formed thin-walled panels 1, the upper keel 2 and the lower keel 3 on site, and then perform the operation of S1 to obtain a single wall that meets the size of the remaining distance. S5. Connect one side of the single wall piece that meets the remaining distance dimensions obtained in S4 to one side of the last single wall piece installed in S3 through the straight wall connecting column 5, thus completing the installation of the straight wall; S6. Insert the corner connecting posts 6 on both sides of the straight wall respectively, and connect another right-angle connecting block 61 through multiple connecting ports 62 or multiple connecting hooks 63 on the right-angle connecting block 61. Then repeat the operations of S3, S4 and S5 to complete the process. S7. Lightweight polymer aggregate concrete grout is injected between the multiple cold-formed thin-walled sealing plates 1 through each of the grouting ports 12, and solidifies after filling to form the lightweight polymer aggregate concrete filling block 4. This design is approved.

[0028] Please refer to the following examples. Figure 8 When cutting multiple cold-formed thin-walled end plates 1 on-site in S4, the cutting must be done on a plane other than the inclined surfaces on both sides of the multiple trapezoidal reinforcing bending grooves 11. This design is to allow the cut of the cold-formed thin-walled end plate 1 to be inserted into the end plate insertion groove 51.
