Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and in particular to a prefabricated wall panel connection structure. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Chinese utility model patent CN219365026U discloses a prefabricated wall panel connection structure, which includes wall panels and connectors disposed between adjacent wall panels. Multiple pressing grooves are formed on the four end faces of the wall panels. The connectors include U-shaped plates, a first hanging plate and a second hanging plate fixedly connected to the two side walls of the U-shaped plates. The first hanging plate is close to the bottom of the U-shaped plate, and a connection hole is provided at the center of the bottom of the U-shaped plate. The space formed between the connectors and the adjacent wall panels is filled with elastic thermal insulation material, and the groove formed by the U-shaped plates of the connectors is filled with waterproof material.

[0004] Although the aforementioned patent can improve the thermal insulation effect at the joint of the wall panel and can also deform the wall panel by squeezing it after it expands and deforms due to heat, thus avoiding stress damage to the wall structure formed by the wall panel, it has the following defects: the pressing groove has a rectangular cross section, the contact area between the hanging plate and the groove wall is small, the shear resistance is weak, the first hanging plate and the second hanging plate are rigid mechanisms, the installation tolerance is small, and the requirements for the dimensional accuracy of the wall panel are high. Utility Model Content

[0005] Therefore, it is necessary to provide a prefabricated wall panel connection structure to overcome the defects mentioned in the background art.

[0006] A prefabricated wall panel connection structure includes wall panels and connectors. A pressing groove is provided at the connection between adjacent wall panels. The end of the connector is embedded in the pressing groove. The pressing groove is a dovetail groove. The end of the connector is provided with an elastic buckle piece. The outward protrusion of the elastic buckle piece forms an arc-shaped contact point, which is connected to the pressing groove through the arc-shaped contact point.

[0007] As a preferred embodiment of the prefabricated wall panel connection structure in this utility model, the inner wall of the pressing groove is provided with anti-slip texture perpendicular to its length direction.

[0008] As a preferred embodiment of the prefabricated wall panel connection structure in this utility model, the connector includes a connecting plate, the end of the connecting plate is provided with a plug-in component that engages with the pressing groove, and the elastic buckle piece is provided on the outer convex side of the plug-in component.

[0009] As a preferred embodiment of the prefabricated wall panel connection structure in this utility model, the connecting plate has a connection hole in the middle.

[0010] As a preferred embodiment of the prefabricated wall panel connection structure in this utility model, the cross-sectional dimension of the plug-in component is smaller than the cross-sectional dimension of the pressing groove.

[0011] As a preferred embodiment of the prefabricated wall panel connection structure in this utility model, a cover plate is also provided between adjacent wall panels.

[0012] The beneficial effects of this utility model are:

[0013] This invention enhances the shear resistance of the wall panel by increasing the contact area between the clamping groove and the connector. The connection between the connector and the clamping groove is changed from a rigid connection to a flexible connection, which can adapt to the small dimensional errors of the clamping groove and the connector, while also facilitating installation.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0028] Example

[0029] A prefabricated wall panel connection structure, such as Figure 1 As shown, the wall panel 1000 and the connector 3000 are arranged side by side with intervals, and adjacent wall panels 1000 are connected to each other by the connector 3000.

[0030] A clamping groove 2000 is provided at the connection between the wall panel 1000 and the adjacent wall panel 1000. The end of the connector 3000 is embedded in the clamping groove 2000 to securely fasten the adjacent wall panels 1000.

[0031] The clamping groove 2000 is a dovetail groove, which increases the contact area between the clamping groove 2000 and the connector 3000, thereby enhancing the shear resistance of the wall panel 1000.

[0032] In this embodiment, the inner wall of the pressing groove 2000 is provided with anti-slip texture 4000 perpendicular to its length direction. At the same time, the anti-slip texture 4000 is provided to enhance the friction between the groove and the connector 3000, thereby strengthening the connection tightness.

[0033] The connector 3000 includes a connecting plate 3100, a plug-in 3200, and an elastic snap-fit ​​piece 3300. A pair of plug-in pieces 3200 are symmetrically spaced apart and used to insert into the clamping groove 2000, providing an installation base for the elastic snap-fit ​​piece 3300. The connecting plate 3100 is located between the pair of plug-in pieces 3200 and is used to connect the pair of plug-in pieces 3200. The elastic snap-fit ​​piece 3300 is provided on the outward protrusion of the plug-in piece 3200 to form an arc-shaped contact point. The plug-in piece 3200 is connected to the clamping groove 2000 through the arc-shaped contact point. This structure changes the connection between the connector 3000 and the clamping groove 2000 from a rigid connection to a flexible connection, which can adapt to the small dimensional errors of the clamping groove 2000 and the connector 3000, while facilitating installation.

[0034] In this embodiment, the connecting plate 3100 has a connecting hole in the middle, and adjacent connecting parts 3000 are connected to each other by bolt assemblies passing through the connecting hole, thereby enhancing the connection stability.

[0035] In this embodiment, the cross-sectional dimensions of the plug 3200 are slightly smaller than those of the clamping groove 2000, so that it can be inserted smoothly and provide connection space for the elastic snap fastener 3300.

[0036] In this embodiment, a cover plate 5000 is also provided between adjacent wall panels 1000. This structure can cover the joint between adjacent wall panels 1000 to prevent the filling material between them from being directly exposed to the external environment, thus reducing the service life.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
