Technical Field

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

[0002] Prefabricated houses are a new type of environmentally friendly and economical prefabricated housing. They use color steel plates as the frame, sandwich panels as the enclosure material, and standard modular series for spatial assembly. The components are connected by bolts. Existing prefabricated houses usually use four L-shaped connecting plates as the support pillars of the house, and then wall panels are installed between the four L-shaped connecting plates to complete the construction. However, the existing wall panels and L-shaped connecting plates are connected by bolts. Prefabricated houses are only temporary housing and are often set up in places such as construction sites.

[0003] The existing prefabricated house connection device is not convenient because prefabricated houses need to be disassembled and installed frequently. The bolt connection method is troublesome when the wall panels need to be removed from the L-shaped connecting plate. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A prefabricated house foundation connection device includes a wall panel body and an L-shaped connecting plate. The L-shaped connecting plate includes a plate body with an insertion groove inside. A fixing protrusion is provided inside the insertion groove. A limiting groove corresponding to the fixing protrusion is provided on the inner side of the wall panel body. The wall panel body is movably engaged inside the insertion groove. A connecting hole is provided on the front side of the plate body. A fixing component is movably installed inside the connecting hole. The fixing component is abutted against the outer side of the wall panel body.

[0006] A further improvement of the present invention is that the fixing component includes a threaded locking post, which is threadedly connected to the inside of the connecting hole. A fixing pressure plate is movably connected to the inner side of the threaded locking post, and a rotating handle is fixedly connected to the outer side of the threaded locking post.

[0007] A further improvement of this utility model is that a sealing rubber gasket is fixedly connected inside the insertion groove, and the sealing rubber gasket is located inside the fixed protrusion.

[0008] A further improvement of this utility model is that the fixing components are symmetrically arranged on the upper and lower sides of the plate.

[0009] A further improvement of this utility model is that a protective pad is provided on the inner side of the fixed pressure plate, and the protective pad is attached to the outer side of the wall panel body.

[0010] A further improvement of this utility model is that the fixed protrusion is movably engaged with the inner side of the limiting groove.

[0011] A further improvement of this utility model is that the sealing rubber gasket is rectangular in shape and adapted to the limiting groove, and the sealing rubber gasket is bonded and fixed in the insertion groove.

[0012] A further improvement of this utility model is that the sealing rubber gasket is flush with the fixing protrusion, and the wall panel body is pressed against the outside of the sealing rubber gasket.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides a basic connection device for prefabricated houses. By matching the limiting groove on the inner side of the wall panel body with the fixing protrusion inside the insertion groove, after the wall panel body is inserted into the insertion groove, the fixing component presses the wall panel body from the outside to make the limiting groove and the fixing protrusion engage, thereby fixing the wall panel body inside the insertion groove, thereby reducing the use of bolts and facilitating disassembly and installation.

[0015] 2. This utility model provides a basic connection device for prefabricated houses. When the wall panel body is pressed against the wall panel body by the fixing component, the sealing rubber pad located inside the insertion groove and inside the fixed protrusion deforms and fits the wall panel body and the L-shaped connecting plate, thereby improving the sealing effect.

[0022] The present invention will now be described in further detail:

[0023] like Figures 1 to 5 As shown, this utility model provides a basic connection device for a prefabricated house, including a wall panel body 1 and an L-shaped connecting plate 2. The L-shaped connecting plate 2 includes a plate body 21, with an insertion groove 22 inside the plate body 21 and a fixing protrusion 23 inside the insertion groove 22. The inner side of the wall panel body 1 is provided with a limiting groove 11 corresponding to the fixing protrusion 23. The wall panel body 1 is movably engaged inside the insertion groove 22. A connection hole 3 is provided on the front side of the plate body 21, and a fixing component 4 is movably installed inside the connection hole 3. The fixing component 4 is abutted against the outer side of the wall panel body 1.

[0024] By matching the limiting groove 11 set inside the wall panel body 1 with the fixing protrusion 23 inside the insertion groove 22, after the wall panel body 1 is inserted into the insertion groove 22, the fixing component 4 presses the wall panel body 1 from the outside to make the limiting groove 11 and the fixing protrusion 23 align and engage, thereby fixing the wall panel body 1 inside the insertion groove 22, thus reducing the use of bolts and facilitating disassembly and installation. At the same time, the sealing rubber gasket 5 set inside the insertion groove 22 and located inside the fixing protrusion 23 is squeezed and deformed when the wall panel body 1 is pressed by the fixing component 4, so that it fits the connection between the wall panel body 1 and the L-shaped connecting plate 2, thereby improving the sealing effect.

[0025] like Figure 5 As shown, the fixing component 4 includes a threaded locking post 41, which is threadedly connected to the inside of the connecting hole 3. A fixing pressure plate 42 is movably connected to the inner side of the threaded locking post 41, and a handle 43 is fixedly connected to the outer side of the threaded locking post 41.

[0026] By rotating the handle 43 located outside the plate 21, the threaded locking pin 41, which is threadedly connected to the inside of the connecting hole 3, is rotated. The threaded locking pin 41 moves into the insertion groove 22 through the threaded engagement between the threaded locking pin 41 and the inside of the connecting hole 3. As the threaded locking pin 41 moves inward, it pushes the fixing plate 42 inward, so that the fixing plate 42 abuts against the outside of the wall panel body 1. The fixing plate 42, together with the threaded locking pin 41, presses and fixes the wall panel body 1, thereby facilitating installation and disassembly.

[0027] like Figure 2 and Figure 3 As shown, a sealing rubber gasket 5 is fixedly connected inside the insertion slot 22, and the sealing rubber gasket 5 is located inside the fixed protrusion 23.

[0028] As the wall panel body 1 moves inward with the fixed pressure plate 42, it squeezes the sealing rubber pad 5. The sealing rubber pad 5 is continuously squeezed and deformed, sticking tightly to the inner wall of the wall panel body 1. The sealing rubber pad 5 improves the sealing effect at the connection between the wall panel body 1 and the L-shaped connecting plate 2.

[0029] like Figure 4 and Figure 5 As shown, the fixing components 4 are symmetrically arranged on the upper and lower sides of the plate 21.

[0030] A protective pad 44 is provided on the inner side of the fixed pressure plate 42, and the protective pad 44 is attached to the outer side of the wall panel body 1.

[0031] The wall panel body 1 is pressed and fixed inside the insertion slot 22 from the outside by the fixing components 4, which are symmetrically arranged inside the plate 21, thereby ensuring the fixing effect of the wall panel body 1 and improving flexibility. The protective pad 44 located inside the fixing pressure plate 42 contacts the wall panel body 1 to improve the fixing stability.

[0032] like Figure 2 As shown, the fixed protrusion 23 is movably engaged with the inner side of the limiting groove 11.

[0033] The wall panel body 1 is fixed by aligning and engaging with the fixed protrusion 23 through the preset limiting groove 11 on the inner side of the wall panel body 1, thereby limiting and fixing the wall panel body 1, and cooperating with the fixing component 4 to ensure the stability of the wall panel body 1.

[0034] like Figure 2 and Figure 3 As shown, the sealing rubber gasket 5 is rectangular in shape to match the limiting groove 11, and the sealing rubber gasket 5 is bonded and fixed in the insertion groove 22.

[0035] The sealing rubber gasket 5 is flush with the fixing protrusion 23, and the wall panel body 1 is pressed against the outside of the sealing rubber gasket 5.

[0036] The sealing rubber pad 5, which is rectangular and flush with the fixed protrusion 23, is squeezed and deformed when the limiting groove 11 and the fixed protrusion 23 are engaged, thereby improving the sealing effect of the connection between the wall panel body 1 and the L-shaped connecting plate 2.

[0037] The working principle of the prefabricated house foundation connection device will be explained in detail below.

[0038] like Figures 1 to 5As shown, by inserting the wall panel body 1 into the insertion slot 22 corresponding to the side of the panel 21, and then rotating the handle 43 located outside the panel 21, the threaded locking pin 41 threaded into the connection hole 3 is rotated. The threaded locking pin 41 moves into the insertion slot 22 through the threaded engagement between the threaded locking pin 41 and the connection hole 3. The fixing plate 42 connected to the inner side of the threaded locking pin 41 is located in the insertion slot 22, and its inner side abuts against the inner wall of the panel 21. As the threaded locking pin 41 moves inward, it pushes the fixing plate 42 inward, so that the fixing plate 42 abuts against the wall panel body 1. Externally, the wall panel body 1 is pushed inward by the fixed pressure plate 42, so that the limiting groove 11 on the inner side of the wall panel body 1 and the fixing protrusion 23 on the inner side of the insertion groove 22 engage with each other. The fixed pressure plate 42 abuts against the fixing protrusion 23 and the limiting groove 11 to fix the wall panel body 1, thereby facilitating disassembly and installation. When the wall panel body 1 moves inward with the fixed pressure plate 42, it squeezes the sealing rubber gasket 5. The sealing rubber gasket 5 is continuously squeezed and deformed to stick tightly to the inner wall of the wall panel body 1. The sealing rubber gasket 5 improves the sealing effect of the connection between the wall panel body 1 and the L-shaped connecting plate 2.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
