Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall technology, specifically to a prefabricated building wall connector. 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 are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods.

[0003] However, current prefabricated wall designs are simple in structure, and most prefabricated walls are assembled by welding. This splicing method is inconvenient for disassembling the spliced ​​prefabricated walls later, which is not conducive to the recycling of prefabricated walls and results in a waste of building resources. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a prefabricated building wall connector that effectively solves the problem of inconvenience in later disassembling of prefabricated walls that are spliced ​​together in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a prefabricated building wall connector, including at least two adjacent walls. Two vertical grooves are symmetrically opened on the outer side of the walls, and a vertical plate is slidably connected between the two opposite vertical grooves. Two sliding grooves are symmetrically opened on the top of the walls, and a fixing frame is slidably connected between the two opposite sliding grooves. Two threaded holes are symmetrically opened inside the walls, vertical plates, and fixing frames about the fixing frames, and multiple threaded holes on the same side are interconnected. A threaded rod is threadedly connected inside the threaded holes.

[0007] According to the above-mentioned prefabricated building wall connector, a fixing groove is provided on one side of the inner wall of the vertical groove, and multiple springs are fixedly installed on one side of the inner wall of the fixing groove. The other end of the multiple springs is fixedly installed with a positioning plate. A positioning hole is provided on the outer side of the fixing frame and at the corresponding position of the positioning plate to engage with it.

[0008] According to the above-mentioned prefabricated building wall connector, a rubber plate is fixedly installed in the middle of the bottom wall of the fixing frame, and a slot for engaging with the rubber plate is provided inside the wall and the vertical plate at the corresponding position.

[0009] According to the above-mentioned prefabricated building wall connector, the top of the positioning plate has a beveled surface on the side facing the fixing frame.

[0010] According to the above-mentioned prefabricated building wall connector, the cross-section of the vertical groove is trapezoidal, and the vertical groove is wider inside and narrower outside.

[0011] According to the above-mentioned prefabricated building wall connector, the cross-section of the fixing frame is U-shaped, and the inner bottom wall of the fixing frame is in contact with the top of the vertical plate.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] This invention uses a vertical plate to initially join two adjacent walls together, then inserts it into a sliding groove. At this point, the threaded holes on the walls, vertical plate, and fixing frame are interconnected. The threaded rod is then inserted into the threaded hole and tightened, thereby fixing the two initially joined walls and improving the stability of the wall joint. When the joined walls are to be disassembled later, the threaded rod is first removed, and then the fixing frame and vertical plate are taken out in sequence to obtain a relatively complete wall, reducing the waste of building resources.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example: Refer to Figures 1 to 3 A prefabricated building wall connector includes at least two adjacent walls 1. Two vertical grooves 2 are symmetrically formed on the outer side of each wall 1. A vertical plate 3 is slidably connected between two opposing vertical grooves 2. Two sliding grooves 4 are symmetrically formed on the top of each wall 1. A fixing frame 5 is slidably connected between two opposing sliding grooves 4. Two threaded holes 6 are symmetrically formed inside each wall 1, vertical plate 3, and fixing frame 5, about the fixing frame 5. Multiple threaded holes 6 on the same side are interconnected. Threaded rods 7 are threaded into the interior of each threaded hole 6. In use, the two walls 1 with the vertical grooves 2 are fitted together. Then, the vertical plate 3 is vertically inserted into the two vertical grooves 2, which initially connects the two walls 1 together. Then, the fixing bracket 5 is inserted into the sliding groove 4. At this time, the threaded holes 6 on the wall 1, the vertical plate 3 and the fixing bracket 5 are interconnected. Then, the threaded rod 7 is inserted into the threaded hole 6 and tightened, which can fix the two walls 1 that are initially spliced ​​together and improve the stability of the splicing of the walls 1. When the spliced ​​walls 1 are disassembled later, the threaded rod 7 is first removed, and then the fixing bracket 5 and the vertical plate 3 are taken out in sequence to obtain a relatively complete wall 1, which reduces the waste of building resources.

[0022] A fixing groove 8 is provided on one inner wall of the vertical groove 2. Multiple springs 9 are fixedly installed on one inner wall of the fixing groove 8. The other end of the multiple springs 9 is fixedly installed with a positioning plate 10. A positioning hole 11 is provided on the outer side of the fixing frame 5 and at the corresponding position of the positioning plate 10 to engage with it. When the fixing frame 5 is inserted into the sliding groove 4, the fixing frame 5 presses the positioning plates 10 on both sides during the movement, so that the two positioning plates 10 move in opposite directions and press the springs 9. At this time, the springs 9 are in a compressed state until the inner bottom wall of the fixing frame 5 contacts the top of the vertical plate 3. At this time, the spring 9 pushes the positioning plate 10 to reset by the rebound force of the spring 9 and inserts the positioning plate 10 into the positioning hole 11, so as to initially fix the fixing frame 5, which facilitates the subsequent installation of the threaded rod 7.

[0023] A rubber plate 12 is fixedly installed in the middle of the inner bottom wall of the fixed frame 5. The wall 1 and the vertical plate 3 are provided with a slot 13 for engaging with the rubber plate 12 at the corresponding position. The rubber plate 12 has a certain coefficient of friction, which can increase the friction between the wall 1 and the vertical plate 3, prevent the vertical plate 3 from sliding easily in the vertical slot 2, and improve the stability of the connection.

[0024] The top of the positioning plate 10 has a beveled surface facing the fixing frame 5. When the fixing frame 5 presses the positioning plate 10 below, the two positioning plates 10 can move in opposite directions to avoid jamming.

[0025] The cross-section of the vertical groove 2 is trapezoidal, and the vertical groove 2 is wider inside and narrower outside, which can prevent the vertical plate 3 from swaying laterally inside the vertical groove 2 and improve the stability of the connection between the two walls 1.

[0026] The cross-section of the fixing frame 5 is U-shaped, and the inner bottom wall of the fixing frame 5 contacts the top of the vertical plate 3, which can fix the vertical plate 3 from above, prevent the vertical plate 3 from shaking up and down during use, and improve the stability of the connection between the two walls 1.

[0027] The working principle of this utility model is as follows: In use, the two walls 1 with the vertical grooves 2 are attached together, and then the vertical plate 3 is vertically inserted into the two vertical grooves 2, thus initially connecting the two walls 1 together. Then, the fixing frame 5 is inserted into the sliding groove 4. During the movement, the fixing frame 5 presses against the positioning plates 10 on both sides, causing the two positioning plates 10 to move in opposite directions and compressing the spring 9. At this time, the spring 9 is in a compressed state until the inner bottom wall of the fixing frame 5 contacts the top of the vertical plate 3. At this time, the spring 9 pushes the wall together. Positioning plate 10 is reset and inserted into positioning hole 11, thereby initially fixing bracket 5. At this time, the threaded holes 6 on wall 1, vertical plate 3 and fixing bracket 5 are interconnected. Then, threaded rod 7 is inserted into threaded hole 6 and tightened, thereby fixing the two initially spliced ​​walls 1 and improving the stability of wall 1 splicing. When the spliced ​​walls 1 are disassembled later, threaded rod 7 is disassembled first, and then fixing bracket 5 and vertical plate 3 are taken out in sequence to obtain a relatively complete wall 1, reducing the waste of building resources.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
