Description

Technical Field

[0001] This utility model relates to the field of prefabricated housing technology, and in particular to a wall connection structure for prefabricated housing. Background Technology

[0002] Prefabricated housing refers to the process of transferring a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site. It is widely used in modern construction.

[0003] A search revealed a Chinese patent (CN222477849U) for a prefabricated house structure, comprising a prefabricated wall panel body. The bottom of the prefabricated wall panel body has several installation slots, each containing a fixed connecting pipe. Inside each connecting pipe are two guide blocks that can move vertically. During the installation of the prefabricated wall panel, the connecting pipe is fixed inside the installation slot, while the guide blocks can move within the connecting pipe and are connected to a connecting ring. When the prefabricated wall panel is lifted, rotating the connecting ring clockwise aligns the slider with the first slide rail. Construction workers can easily determine the position of the installation slot based on the position of the connecting ring, avoiding the inconvenience of traditionally relying on a mirror for observation. This significantly improves installation efficiency, ensures the smooth entry of the connecting steel bars into the connecting pipe, and achieves precise installation of the prefabricated wall panel.

[0004] However, during assembly, the connection between two walls is currently mostly achieved using tie rods or concrete. In prefabricated houses, due to the division of rooms or functional areas, there are many L-shaped or T-shaped connections between walls. Using conventional connection methods results in poor stability and inconvenience in operation. Therefore, this application is made. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, this utility model provides a prefabricated house wall connection structure, which has the technical characteristics of facilitating the assembly of walls and being easy to operate.

[0006] The technical solution adopted by this utility model is as follows: it includes precast walls and fittings, wherein the fittings are precast on the precast walls, and two precast walls are assembled and connected by the fittings.

[0007] The assembly includes a first embedded part, a second embedded part, and a connector. The first embedded part and the second embedded part are respectively cast on two different precast walls, and the first embedded part and the second embedded part are connected by the connector.

[0008] The first embedded component includes an embedded box, an insert, and a wedge block. The embedded box is embedded inside the precast wall, and the insert is welded to the embedded box. A connecting through hole is provided at the middle position where the insert connects to the embedded box. A threaded groove is provided inside the connecting through hole to be threadedly connected to the connector. The wedge block is engaged with one side of the insert, and both the insert and the wedge block are located outside the precast wall.

[0009] The second embedded component includes a dovetail box and a limiting plate. Both the dovetail box and the limiting plate are cast inside the precast wall. The opening side of the dovetail box is connected to the outside. The insert and the wedge block are inserted into the dovetail box through the opening side. The connector passes through the limiting plate, the dovetail box, the wedge block and the insert in sequence and is threadedly connected to the threaded groove, and extends into the interior of the embedded box.

[0010] To facilitate the wedge block in opening the insert and connecting it to the inside of the dovetail box, this utility model is improved by providing a notch on one side of the insert with a width smaller than the width of the wedge block. The notch has symmetrically arranged slides inside, and slide bars are fixedly installed on both sides of the wedge block, with the slide bars slidably engaging with the slides.

[0011] To improve the connection between the embedded box and the precast wall, the present invention is improved by welding and fixing a first embedded steel cage on the upper and lower sides of the embedded box and on the side opposite to the insert, and the first embedded steel cage is cast inside the precast wall.

[0012] To improve the stability of the connection between the dovetail box and the precast wall, the present invention is improved by welding a second pre-embedded steel cage on both sides of the dovetail box, and the second pre-embedded steel cage is cast inside another precast wall.

[0013] To ensure a secure connection between the first and second embedded parts, this invention includes an improvement whereby the connecting part comprises a screw rod, one end of which is threadedly connected to the threaded groove, and the end of the screw rod is provided with a retaining groove that extends into the interior of the embedded box.

[0014] To facilitate the extrusion of glue from the inside of the adhesive pack and to fill the gap between the screw and the threaded groove, thus preventing the screw from loosening, this utility model improves upon the following: a vertical sliding groove is provided inside the embedded box, and pressure plates are symmetrically installed inside the embedded box. The two sides of the pressure plates are slidably engaged with the sliding groove, and a connecting rope is fixedly installed between the vertically distributed pressure plates, with the connecting rope engaging with the groove.

[0015] To improve the stability of the screw during long-term use, this utility model is improved by placing a glue-containing package inside the pre-embedded box between the pressure plates.

[0016] To improve the stability of the connection between the insert and the dovetail box, the present invention is improved by fixing rubber sheets on both sides of the insert, and pressing one side of the rubber sheet against the inner wall of the dovetail box.

[0017] The beneficial effects of this utility model are: 1. This utility model uses a first embedded part and a second embedded part to be cast into the interior of the precast wall to form an integrated structure. During assembly, the first embedded part and the second embedded part are fastened together by a connector, so that the precast wall is stably connected and the assembly operation is convenient.

[0018] 2. This utility model uses a wedge block. During assembly, the wedge block moves into the notch, causing the insert to deform, thereby ensuring a stable connection between the insert and the dovetail box, preventing detachment and improving the firmness after assembly.

[0019] 3. This utility model uses a rubber pack and a pressure plate. When the screw is screwed in, the rubber pack is punctured, and the glue inside the rubber pack is squeezed out through the pressure plate to fill the gap between the thread groove and the connection position of the screw, thereby preventing the screw from loosening and improving its service life.

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, this embodiment provides a prefabricated house wall connection structure, including a prefabricated wall 1 and an assembly 2. The assembly 2 is precast on the prefabricated wall 1, and the two prefabricated walls 1 are connected by the assembly 2. After assembly, the two prefabricated walls 1 form an L-shaped or T-shaped distribution structure, which facilitates the division of rooms or functional areas in the prefabricated house and makes assembly convenient.

[0023] The assembly 2 includes a first embedded part 21, a second embedded part 22, and a connector 23. The first embedded part 21 and the second embedded part 22 are respectively cast onto two different precast walls 1, and the first embedded part 21 and the second embedded part 22 are connected by the connector 23. This facilitates prefabrication in the factory and then transportation to the site for assembly. It is easy to operate; only the connector 23 needs to be operated to connect and tighten the first embedded part 21 and the second embedded part 22 to achieve the effect of assembling the two precast walls 1.

[0024] The first embedded part 21 includes an embedded box 2101, an insert 2102, and a wedge block 2103. The embedded box 2101 is embedded inside the precast wall 1, and the insert 2102 is welded to the embedded box 2101. A connecting through hole 2104 is provided at the middle position where the insert 2102 connects to the embedded box 2101. A threaded groove 2105 is provided inside the connecting through hole 2104 to be threadedly connected to the connector 23, thereby facilitating the connection of the connector 23 through the second embedded part 22 and the threaded groove 2105. The first embedded part 21 and the second embedded part 22 are connected and fixed together. The wedge block 2103 is engaged on one side of the insert 2102. Both the insert 2102 and the wedge block 2103 are located outside the precast wall 1, which facilitates the insertion of the insert 2102 into the interior of the second embedded part 22. When pressed, the wedge block 2103 moves into the interior of the insert 2102, so that the wedge block 2103 opens the insert 2102, and the insert 2102 deforms, improving the connection effect between the first embedded part 21 and the second embedded part 22.

[0025] The second embedded part 22 includes a dovetail box 2201 and a limiting plate 2202. Both the dovetail box 2201 and the limiting plate 2202 are cast inside the precast wall 1. The limiting plate 2202 limits one end of the connector 23, and the open side of the dovetail box 2201 is connected to the outside. The insert 2102 and the wedge block 2103 are inserted into the dovetail box 2201 through the open side. The connector 23 passes through the limiting plate 2202, the dovetail box 2201, the wedge block 2103, and the insert 2102 in sequence and is threadedly connected to the threaded groove 2105, extending into the embedded box 2101. During assembly, the insert 2102 and the wedge block 2103 are inserted into the threaded groove 2105. Inside the dovetail box 2201, when the two prefabricated walls 1 are pressed together, the inner side of the dovetail box 2201 presses against one end of the wedge block 2103, causing the wedge block 2103 to move into the insert 2102, opening the insert 2102 so that the insert 2102 fits against the inner walls of both sides of the dovetail box 2201, preventing the insert 2102 from separating from the dovetail box 2201, and improving the firmness of the connection. Then, the first embedded part 21 and the second embedded part 22 are further connected by the connector 23, so that the two prefabricated walls 1 are firmly assembled together. In use, multiple fittings 2 can be pre-cast on the prefabricated walls 1 to further improve the connection stability after assembly.

[0026] The insert 2102 has a notch 2106 on one side, the width of which is smaller than the width of the wedge 2103. The notch 2106 has symmetrically arranged slides 2107 inside. Slide strips 2108 are fixedly installed on both sides of the wedge 2103. The slide strips 2108 slide and engage with the slides 2107. Therefore, when the wedge 2103 is blocked by the inner wall of the dovetail box 2201, the insert 2102 continues to be inserted into the dovetail box 2201, allowing the wedge 2103 to pass through the slides 2108 along the slides 2107 at the notch 2106. The internal movement of 6 expands the notch 2106 on the insert 2102, achieving the effect of riveting the insert 2102 and the dovetail box 2201. Rubber sheets 2114 are fixedly installed on both sides of the insert 2102, and one side of the rubber sheet 2114 is pressed against the inner wall of the dovetail box 2201. After the insert 2102 is expanded, the rubber sheet 2114 fills the space between the outer side of the insert 2102 and the inner wall of the dovetail box 2201, improving the anti-slip performance, reducing the cracking phenomenon caused by rigid contact, and improving the firmness of the connection.

[0027] The first embedded steel cage 2109 is welded and fixedly installed on the upper and lower sides of the embedded box 2101 and on the side opposite to the insert 2102. The first embedded steel cage 2109 is cast inside the precast wall 1. The second embedded steel cage 2203 is welded on both sides of the dovetail box 2201. The second embedded steel cage 2203 is cast inside another precast wall 1. Through the first embedded steel cage 2109 and the second embedded steel cage 2203, the first embedded part 21 and the precast wall 1 can be firmly connected, and the second embedded part 22 and the precast wall 1 can be firmly connected, forming an integrated structure after casting, which improves the connection stability of the protection after assembly.

[0028] The connector 23 includes a screw 2301. One end of the screw 2301 is threadedly connected to the threaded groove 2105, and the end of the screw 2301 is provided with a retaining groove 2302. The retaining groove 2302 extends into the interior of the embedded box 2101. The screw 2301 has a T-shaped structure. After connection, one end of the screw 2301 is pressed against the limiting plate 2202, and the other end extends into the interior of the embedded box 2101 after passing through the threaded groove 2105.

[0029] The embedded box 2101 has a vertically formed sliding groove 2110 inside, and pressure plates 2111 are symmetrically installed inside the embedded box 2101. The two sides of the pressure plates 2111 are slidably engaged with the sliding groove 2110. A connecting rope 2112 is fixedly installed between the upper and lower distributed pressure plates 2111, and the connecting rope 2112 is engaged with the slot 2302. Inside the embedded box 2101, between the pressure plates 2111, there is a glue bag 2113 containing glue. The glue can be one of epoxy or epoxy modified system, acrylic glue, and copper phosphate inorganic glue. The screw 2301 extends to the embedded box 21101. After moving and rotating inside 01, the screw 2301 punctures the rubber package 2113, and the slot 2302 on the screw 2301 catches the connecting rope 2112. As it continues to rotate, the connecting rope 2112 wraps around the screw 2301, creating a pulling force on the pressure plate 2111. This causes the two pressure plates 2111 to move relative to each other along the slide groove 2110, squeezing the rubber package 2113 and forcing the glue into the gap between the threaded groove 2105 and the screw 2301. After curing, this improves the stability of the connection between the screw 2301 and the threaded groove 2105, preventing loosening and extending service life.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
