Description

Technical Field

[0001] This utility model relates to the field of prefabricated concrete wall technology, specifically to a crack-resistant prefabricated concrete wall. Background Technology

[0002] Buildings assembled on-site from prefabricated components are called prefabricated buildings. Based on the form of prefabricated components and construction methods, they are classified into five types: block buildings, panel buildings, box-type buildings, frame-panel buildings, and lift-slab / lift-floor buildings. With urban development, housing construction is moving towards intelligent prefabricated buildings.

[0003] Patent document CN220203064U discloses a prefabricated building wall structure, relating to the field of prefabricated building wall structure technology. It includes a first prefabricated building wall body and a second concrete baffle. A first concrete partition is provided on the right side of the first prefabricated building wall body, and a first concrete block is provided in front of the first concrete partition. A first grouting groove is formed on the front of the outer surface of the first concrete block, and a first reinforcing rib is provided inside the first grouting groove. Compared with existing ordinary prefabricated building wall structures, this prefabricated building wall structure pours concrete from a grouting hole opened above the outer surface of the second concrete baffle into a second grouting groove opened in the first concrete partition, while simultaneously pouring concrete into the first grouting groove. Furthermore, the inclusion of a first reinforcing rib and a second reinforcing rib increases the strength of the wall joints and prevents cracking of the subsequently poured concrete.

[0004] Although the aforementioned application documents simultaneously pour concrete into the first pouring tank and provide a first reinforcing rib and a second reinforcing rib to increase the strength of the wall joint and prevent the later-poured concrete from cracking, the assembly process still uses a manual pouring method, which reduces assembly efficiency.

[0005] Therefore, the crack-resistant prefabricated concrete wall is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a crack-resistant prefabricated concrete wall, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a crack-resistant concrete wall, wherein the crack-resistant concrete wall is internally equipped with an installation device for assembly;

[0008] The installation device includes an installation hole, a connecting block is fixedly connected to the top of the crack-resistant concrete wall, an insertion hole is opened on the front of the connecting block, a first spring is fixedly connected to the front of the inner wall of the crack-resistant concrete wall, an installation block is fixedly connected to the front of the first spring, a rectangular limiting block is fixedly connected to the top of the installation block, and a buckle assembly is fixedly connected to the front of the crack-resistant concrete wall.

[0009] Preferably, the buckle assembly includes slide rods, and multiple sets of slide rods are fixedly connected to the front of multiple sets of mounting blocks, with connecting rods fixedly connected to the front of the multiple sets of slide rods.

[0010] Preferably, a fixing rod is fixedly sleeved on the outer wall of the slide rod, and a plug rod for inserting into the plug hole is fixedly connected to the back of the fixing rod.

[0011] Preferably, the front of the mounting block has rounded corners for insertion into two crack-resistant concrete walls, and the back of the insertion rod has rounded corners for insertion into two crack-resistant concrete walls.

[0012] Preferably, the crack-resistant concrete wall is internally equipped with an expansion device for improving the sealing performance of the two crack-resistant concrete walls after assembly.

[0013] Preferably, the expansion device includes an installation groove, which is formed on the front side of the inner wall of the crack-resistant concrete wall. A hydraulic chamber is fixedly connected to the front side of the inner wall of the installation groove. A hydraulic rod is slidably connected to a piston at one end inside the hydraulic chamber. A connecting plate is fixedly connected to the side of the hydraulic rod. A second spring is movably sleeved on the outer wall of the hydraulic rod.

[0014] Preferably, an airbag is fixedly connected to the front of the inner wall of the mounting groove, a connecting pipe is fixedly connected to the top of the airbag, the end of the connecting pipe away from the airbag is fixedly connected to the bottom of the hydraulic chamber, and the two ends of the second spring are fixedly connected to the side of the connecting plate and the side of the hydraulic chamber, respectively.

[0015] Compared with the prior art, this utility model provides a crack-resistant prefabricated concrete wall, which has the following beneficial effects:

[0016] First, by using a combination of mounting blocks, sliding rods, fixing rods, and insert rods, two crack-resistant concrete walls can be quickly and accurately assembled when spliced ​​together, eliminating the need for manual pouring. This solves the problem of low efficiency in traditional assembly methods, greatly improves assembly efficiency, shortens the construction cycle, and ensures that the insert rods can be accurately inserted into the insertion holes of the connecting blocks, thereby achieving a stable connection between the two crack-resistant concrete walls and enhancing the overall stability and reliability of the wall structure.

[0017] 2. Before assembly, apply adhesive to the left side of the airbag. When the two crack-resistant concrete walls approach each other, the movement of the hydraulic rod increases the pressure inside the hydraulic chamber, connecting pipe, and airbag, causing the airbag to inflate and adhere tightly to the right side of the left crack-resistant concrete wall. This process utilizes the expansion of the airbag and the adhesive effect of the adhesive to effectively enhance the seal between the two walls, preventing moisture and air from seeping in through gaps and improving the waterproof and windproof performance of the walls.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] See Figures 1-4 This embodiment provides a crack-resistant prefabricated concrete wall, including a crack-resistant concrete wall 1, and an installation device 2 for assembly is installed inside the crack-resistant concrete wall 1.

[0026] The mounting device 2 includes a mounting hole 21. A connecting block 22 is fixedly connected to the top of the crack-resistant concrete wall 1. An insertion hole is provided on the front of the connecting block 22. A first spring 24 is fixedly connected to the front of the inner wall of the crack-resistant concrete wall 1. A mounting block 23 is fixedly connected to the front of the first spring 24. A rectangular limiting block 29 is fixedly connected to the top of the mounting block 23. A buckle assembly is fixedly connected to the front of the crack-resistant concrete wall 1.

[0027] The snap-fit ​​assembly includes slide rods 25, multiple sets of slide rods 25 are fixedly connected to the front of multiple sets of mounting blocks 23, and connecting rods 26 are fixedly connected to the front of the multiple sets of slide rods 25.

[0028] A fixing rod 27 is fixedly sleeved on the outer wall of the slide rod 25, and a plug rod 28 for inserting into the plug hole is fixedly connected to the back of the fixing rod 27.

[0029] The mounting block 23 has rounded corners on the front for inserting two anti-cracking concrete walls 1, and the insertion rod 28 has rounded corners on the back for inserting two anti-cracking concrete walls 1.

[0030] When the above-mentioned equipment is used, the two anti-cracking concrete walls 1 are spliced ​​together. The right side of the anti-cracking concrete wall 1 is assembled with the groove on the left side of the anti-cracking concrete wall 1. The right side of the anti-cracking concrete wall 1 will press the mounting block 23, causing the mounting block 23 to move backward. The first spring 24 is compressed and slides on the inner wall of the anti-cracking concrete wall 1 through the limiting block 29 to prevent the mounting block 23 from rotating during movement. When the mounting block 23 moves backward, it drives the sliding rod 25 to move backward. The sliding rod 25 drives the fixing rod 27 to move backward. The fixing rod 27 drives the insertion rod 28 to move backward. When the anti-cracking concrete wall 1 continues to move, the mounting block 23 will drive the sliding rod 25 to move in a forward and backward trajectory during the process of inserting into the mounting hole 21. When the mounting block 23 is fully inserted into the interior of the mounting hole 21, it will drive the insertion rod 28 to be inserted into the insertion hole of the connecting block 22, thus completing the assembly of the two anti-cracking concrete walls 1.

[0031] Example 2

[0032] See Figures 1-4 Based on Example 1, the crack-resistant concrete wall 1 is equipped with an expansion device 3 to improve the sealing performance of the two crack-resistant concrete walls 1 after assembly.

[0033] The expansion device 3 includes an installation groove 31, which is opened on the front of the inner wall of the crack-resistant concrete wall 1. A hydraulic chamber 32 is fixedly connected to the front of the inner wall of the installation groove 31. A hydraulic rod 33 is slidably connected to a piston at one end inside the hydraulic chamber 32. A connecting plate 35 is fixedly connected to the side of the hydraulic rod 33. A second spring 36 is movably sleeved on the outer wall of the hydraulic rod 33.

[0034] An airbag 37 is fixedly connected to the front of the inner wall of the mounting groove 31. A connecting pipe 34 is fixedly connected to the top of the airbag 37. The end of the connecting pipe 34 away from the airbag 37 is fixedly connected to the bottom of the hydraulic chamber 32. The two ends of the second spring 36 are fixedly connected to the side of the connecting plate 35 and the side of the hydraulic chamber 32, respectively.

[0035] When the above-mentioned equipment is used, water is applied to the left side of the airbag 37 before assembly. When the two anti-cracking concrete walls 1 approach each other, the anti-cracking concrete wall 1 on the left side will squeeze the connecting plate 35 of the anti-cracking concrete wall 1 on the right side. The connecting plate 35 drives the hydraulic rod 33 to move to the right, and the second spring 36 is compressed. During the process of the hydraulic rod 33 moving to the right, the internal pressure of the hydraulic chamber 32, the connecting pipe 34, and the airbag 37 increases, causing the airbag 37 to expand, so that the side of the airbag 37 with glue is tightly attached to the right side of the anti-cracking concrete wall 1 on the left side.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
