Description

Technical Field

[0001] This utility model relates to the field of prefabricated building connection technology, specifically a prefabricated building connection device. Background Technology

[0002] Prefabricated building wall panels are integrally formed with marble and can be installed in the factory in one go. On-site assembly is all that is needed, which improves quality and efficiency. No double-sided plastering is required after installation. The wall and the decoration surface are completed in one step, which is energy-saving and environmentally friendly.

[0003] For example, Chinese patent CN216616418U (A Prefabricated Building Connection Device) includes an assembly plate and connectors. First, a U-shaped plate is bolted onto a first column, and the plate body is assembled onto the U-shaped plate. A second U-shaped plate is placed in a second mounting groove. A tube body, passing through a through hole and mounting hole, is partially located within the hollow section. One hand holds the tube body, while the other hand pulls a drive rod to one end. The drive rod causes one end of a bent support rod to rotate counterclockwise around a hinge axis. When one end of the bent support rod forms an angle of approximately 45 degrees with the tube body, the pull on the drive rod is stopped, and the nut is rotated until it is fully fitted onto the U-shaped plate. Since the U-shaped plate protrudes from the second mounting groove at this point, the protrusion is used to assemble the first mounting groove of the next set of plates. This process continues until the last set of assembly plates is assembled onto the U-shaped plate on the second column. This facilitates both initial assembly and subsequent disassembly of the prefabricated building connection device.

[0004] However, when connecting existing wall panels to marble, profiles are often used, which can easily lead to gaps at the joints. The profiles are prone to deformation and damage later, making replacement inconvenient. Furthermore, the connection structure is complex, time-consuming, and labor-intensive. Therefore, this method does not meet the current needs. To address this, we propose a prefabricated building connection device. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated building connection device to solve the problems mentioned in the background art, which are that when connecting existing wall panels and marble, profiles are often used for connection, gaps are easy to appear at the connection, the profiles are prone to deformation and damage in the later stage, replacement is inconvenient, and the connection structure is complex, time-consuming and labor-intensive.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated building connection device, comprising: a first assembly component, a second assembly component provided on both sides of the first assembly component, a top edge strip provided at the top of the first assembly component, a bottom edge strip provided at the bottom of the first assembly component, a limiting component provided at the connection between the first assembly component and the second assembly component, and the first assembly component and the second assembly component being assembled through the limiting component.

[0007] Preferably, both the first assembly component and the second assembly component include a wall panel, and a first connecting groove is provided on the rear surface of one side edge of the wall panel. Multiple first connecting grooves are provided and are distributed in an equidistant array.

[0008] Preferably, the rear surface of the other edge of the wall panel is provided with a second connecting groove, and there are multiple second connecting grooves, which are distributed in an equidistant array, are horizontally aligned with the first connecting groove, and have the same size. The limiting component is inserted into the first connecting groove and the second connecting groove.

[0009] Preferably, the inner surfaces of both the first connecting groove and the second connecting groove are provided with limiting protrusions, and multiple limiting protrusions are provided.

[0010] Preferably, both the first assembly component and the second assembly component are further provided with a base block, and the base block is located on the rear surface of the wall panel. Multiple base blocks are provided and distributed in an equidistant array.

[0011] Preferably, the limiting component includes a limiting connecting plate and a limiting groove, wherein the limiting groove is located on the rear surfaces of both ends of the limiting connecting plate, and the limiting protrusion is inserted into the limiting groove.

[0012] Preferably, one end of both the top edge strip and the bottom edge strip is provided with a hanging strip, which is L-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model achieves the connection and alignment effect between the first and second assembly components by inserting the two ends of the limiting connecting plate into the first connecting groove of the first assembly component and the second connecting groove of the second assembly component, respectively. This prevents vertical displacement and improves stability. The limiting protrusion is inserted into the limiting groove to limit the limiting connecting plate, preventing it from falling or shifting position. At the same time, the limiting connecting plate also limits the first and second assembly components, preventing lateral displacement. This ensures the stability and firmness of the assembly of the first and second assembly components. In this way, the assembly of the first and second assembly components is achieved through a single limiting component. There is no need to measure the dimensions on-site, cut the wall panel surface, and then install the profile. It also reduces the risk of damage to the gap between the first and second assembly components, improving safety and firmness, saving labor, and solving the problem that when connecting wall panels and marble, profiles are often used for connection, which easily leads to gaps at the connection, easy deformation and damage of the profiles later, inconvenient replacement, and complex connection structure, which is time-consuming and labor-intensive.

[0015] (2) By setting a base block on the back surface of the wall panel, when the wall panel is installed on the wall, the base block contacts the wall surface, which avoids the wall panel from contacting the wall and causing dampness and mold damage in the later stage, thus improving the service life. After the first assembly component and the second assembly component are assembled, the top edge strip and the bottom edge strip are fixed to the upper and lower ends of the wall panel by wrapping latex, which has an edge finishing effect on the upper and lower ends of the first assembly component and the second assembly component, making it easy to install.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a prefabricated building connection device, comprising: a first assembly component 1, second assembly components 2 on both sides of the first assembly component 1, a top edge strip 3 at the top of the first assembly component 1, a bottom edge strip 13 at the bottom of the first assembly component 1, a limiting component 5 at the connection between the first assembly component 1 and the second assembly component 2, and the first assembly component 1 and the second assembly component 2 are assembled by the limiting component 5, both the first assembly component 1 and the second assembly component 2 include a wall panel 6, a first connecting groove 7 is provided on the rear surface of one side edge of the wall panel 6, and multiple first connecting grooves 7 are provided and are distributed in an equidistant array, the rear surface of the other side edge of the wall panel 6 is provided with a second connecting groove 10, and multiple second connecting grooves 10 are provided and are distributed in an equidistant array, horizontally aligned with the first connecting grooves 7, and having the same size, the limiting component 5 is inserted into the first connecting grooves 7 and the second connecting grooves 10;

[0023] The groove is pre-selected to be cut on the back surface of wall panel 6, which is completed during the manufacturing process;

[0024] When assembling the first assembly component 1 and the second assembly component 2, first align the first assembly component 1 and the second assembly component 2, and then insert both ends of the limiting connecting plate 11 into the first connecting groove 7 of the first assembly component 1 and the second connecting groove 10 of the second assembly component 2 respectively, so as to achieve the connection and alignment effect of the first assembly component 1 and the second assembly component 2, making it less likely to shift vertically and improving stability.

[0025] The inner surfaces of the first connecting groove 7 and the second connecting groove 10 are provided with limiting protrusions 8, and there are multiple limiting protrusions 8. The first assembly component 1 and the second assembly component 2 are also provided with bottom blocks 9, and the bottom blocks 9 are located on the rear surface of the wall panel 6. There are multiple bottom blocks 9, and the multiple bottom blocks 9 are distributed in an equidistant array. The limiting component 5 includes a limiting connecting plate 11 and a limiting groove 12, and the limiting groove 12 is located on the rear surfaces of both ends of the limiting connecting plate 11. The limiting protrusions 8 are inserted into the limiting groove 12. One end of the top edge strip 3 and the bottom edge strip 13 is provided with a hanging strip 4, which is L-shaped.

[0026] The limiting protrusion 8 is inserted into the limiting groove 12 to limit the limiting connecting plate 11, preventing it from falling or shifting position. At the same time, the limiting connecting plate 11 also limits the first assembly component 1 and the second assembly component 2, preventing lateral position shift and ensuring the stability and firmness of the assembly of the first assembly component 1 and the second assembly component 2. In this way, the assembly of the first assembly component 1 and the second assembly component 2 is achieved through a single limiting component 5, eliminating the need for on-site dimensional measurement, surface cutting of the wall panel 6, and subsequent installation of the profile. It also reduces the likelihood of damage to the filling of the gap between the first assembly component 1 and the second assembly component 2, improving safety and firmness, and saving labor.

[0027] When installing wall panel 6 on the wall, the base block 9 contacts the wall to prevent wall panel 6 from coming into contact with the wall and causing dampness, mold and damage later, thus improving its service life.

[0028] After the first assembly component 1 and the second assembly component 2 are assembled, the top edge trim 3 and the bottom edge trim 13 are fixed to the upper and lower ends of the wall panel 6 respectively by applying latex, which provides an edge trimming effect to the upper and lower ends of the first assembly component 1 and the second assembly component 2, making installation easier.
