This structure greatly saves the time of on-site pouring construction, shortens the construction period, simplifies the on-site operation process, and avoids the occurrence of on-site construction accidents. However, this structure makes it easy for cracks to appear at the connection between the internal partition walls constructed later and the main body of the building during later use, which in turn leads to widespread wall cracking and reduced insulation effect, which has a certain impact on the quality of the internal construction of the building structure. Utility Model Content

[0018] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.
[0019] Reference Figure 1The present invention is a self-insulating interior partition wall structure that avoids cracking. The main structure includes multiple interior wall bodies 2 arranged between the top and bottom of the building body 1. The interior wall bodies 2 are prefabricated in the factory and then transported to the construction site for installation. Expanded polystyrene particles are added therein to reduce the weight of the interior wall bodies 2 while ensuring the structural strength. This allows the length of a single interior wall body 2 to be designed longer, thereby reducing the number of interior wall bodies 2 used, reducing the number of vertical connection seams between the interior wall bodies 2, and reducing the probability of cracking of the interior partition wall. The top of the interior wall body 2 contacts the top of the building body 1, and the bottom of the interior wall body 2 contacts the bottom of the building body 1. The two sides of the inner wall body 2 are respectively provided with a protrusion 3 and a groove 4. The protrusion 3 and one side of the inner wall body 2 are integrally formed by casting. The groove 4 is recessed inwardly from the side of the inner wall body 2. The protrusion 3 is movably plugged into the groove 4 on the adjacent inner wall body 2. Such a structure allows the two adjacent inner wall bodies 2 to be constructed and installed. The position is restricted by the protrusion 3 and the groove 4, so that the structure of the adjacent inner wall bodies 2 is more stable and less likely to be misaligned, thereby reducing the probability of cracking of the inner partition wall. The top of the inner wall body 2 is provided with embedded steel bars 5. The embedded steel bars 5 are embedded inside when the inner wall body 2 is prefabricated and cast in the factory. After prefabrication, they are integrally formed with the inner wall body 2. The embedded steel bars 5 extend to the top of the building main body 1. Such a structure can install the inner wall main body 2 on the top of the building main body 1 before the top of the building main body 1 is cast. The embedded steel bars 5 are cast inside when the top of the building main body 1 is cast. As a result, the top of the building main body 1 is fixed to the top of the inner wall main body 2 through the embedded steel bars 5 after construction, thereby greatly improving the firmness of the connection between the top of the inner wall main body 2 and the top of the building main body 1. Compared with the form of late installation, the probability of cracking is greatly reduced. The bottom of the building main body 1 is fixed with a plurality of U-shaped clips 6 by bolts. The U-shaped clips 6 are sleeved on the outside of the bottom of the inner wall main body 2. The setting of the U-shaped clips 6 can be This makes it difficult for the bottom of the inner wall body 2 to move relative to the bottom of the building body 1, thereby making the structure of the bottom connection more solid and reducing the chance of cracking at the bottom connection. Such a structure makes the structure of the inner wall body 2 more solid than the building body 1, and is less likely to crack during later use, thereby ensuring the overall quality and thermal insulation performance of the inner partition wall. The side of the inner wall body 2 is movably connected with a temporary support rod 7. The temporary support rod 7 provides support to the inner wall body 2 during the construction process to prevent the inner wall body 2 from tipping over or dislocating, thereby ensuring the firmness of the inner wall body 2 during the construction process. After the construction is completed, the temporary support rod 7 is removed to ensure the firmness of the inner wall body 2 during the construction process.
[0020] Preferably, a buffer layer 8 is provided on the top of the inner wall body 2, and the buffer layer 8 is fixed to the top of the inner wall body 2 by anchor bolts, which are generally made of polystyrene. The embedded steel bars 5 pass through the buffer layer 8 and extend to the top of the building body 1. The embedded steel bars 5 are used to reinforce the buffer layer 8 between the inner wall body 2 and the building body 1 to improve the firmness of the buffer layer 8. The setting of the buffer layer 8 can reduce the possible pressure impact on the installed inner wall body 2 during the pouring construction on the top of the building body 1, thereby protecting the structural integrity of the inner wall body 2.
[0021] Preferably, refer to Figure 2 Both ends of the bottom of the inner wall body 2 are provided with a clamping groove 9, which is recessed inward from the surface of the bottom of the inner wall body 2. The U-shaped clamping plate 6 is simultaneously engaged with the clamping grooves 9 on two adjacent inner wall bodies 2. The provision of the clamping groove 9 makes the connection between the U-shaped clamping plate 6 and the inner wall body 2 more secure, making it difficult for the bottom of the inner wall body 2 to move relative to the U-shaped clamping plate 6, thereby improving the firmness of the connection between the inner wall body 2, the U-shaped clamping plate 6 and the bottom of the building body 1, and further reducing the possibility of cracking.
[0022] Preferably, a fixing anchor 10 is provided at the bottom of the U-shaped pallet 6, and the fixing anchor 10 extends to the bottom of the building body 1. The provision of the fixing anchor 10 makes the connection and fixation between the U-shaped pallet 6 and the bottom of the building body 1 more convenient and efficient. At the same time, the structure is simpler and is not easy to encroach on the external space of the inner wall body 2, thereby ensuring the overall aesthetics of the inner wall body 2.
[0023] Preferably, both ends of the temporary support rod 7 are rotatably connected to a fixing plate 11 through a pin or a hinge, one of the fixing plates 11 is fixedly connected to the side of the inner wall body 2 by an anchor bolt, and the other fixing plate 11 is fixedly connected to the bottom of the building body 1 by an anchor bolt. Such a structure can fix the fixing plate 11 at the top of the temporary support rod 7 at different heights of the side of the inner wall body 2 according to actual use needs, and utilize the rotatable connection between the temporary support rod 7 and the fixing plate 11 so that the bottom fixing plate 11 can be smoothly fixed to the bottom of the building body 1, thereby greatly improving the fixing effect of the temporary support rod 7 on the inner wall bodies 2 of different heights, and meeting the needs of temporary fixed support of various inner wall bodies 2.
[0024] Preferably, both of the fixing plates 11 are rotatably connected to a fixing column 12 via a pin or a hinge, wherein one of the fixing columns 12 is rotatably connected to the end of the temporary support rod 7, and the other fixing column 12 is threadedly connected to the end of the temporary support rod 7. Such a structure realizes the rotatable connection between the fixing plate 11 and the two ends of the temporary support rod 7 through the rotating fixing column 12. By rotating the temporary support rod 7, the fixing plate 11 at one end can be extended relative to the end of the temporary support rod 7 under the action of the threaded connection, so that the distance between the fixing plates 11 at both ends can be adaptively adjusted, further improving the adaptability of the temporary support rod 7 to support the inner wall body 2, and improving the flexibility of the support structure.
[0025] Working principle: The structure of the utility model sets embedded steel bars 5 on the top of the inner wall main body 2, and the embedded steel bars 5 extend to the top of the building main body 1. The embedded steel bars 5 are connected to the top of the building main body 1 after pouring construction on the top of the building main body 1, so that the inner wall main body 2 can be constructed synchronously with the building main body 1, so that the top of the inner wall main body 2 and the building main body 1 are connected as one after construction, making the structure of the connection more solid and less prone to cracking in later use. A plurality of U-shaped card plates 6 are provided at the bottom of the building main body 1, and the U-shaped card plates 6 are sleeved on the outside of the bottom of the inner wall main body 2. Such a structure uses the U-shaped card plates 6 to reinforce the bottom of the inner wall main body 2 and the building main body 1. The inner wall body 2 is fixed, and the inner wall body 2 is prevented from tilting or dislocating relative to the building body 1, thereby further improving the firmness of the structure of the inner wall body 2; protrusions 3 and grooves 4 are respectively provided on both sides of the inner wall body 2, and the protrusions 3 are movably plugged into the grooves 4 on the adjacent inner wall body 2, and the side surfaces of the inner wall body 2 are movably connected with temporary support rods 7. Such a structure utilizes the cooperation of the protrusions 3 and the grooves 4 to make it difficult for adjacent inner wall bodies 2 to be dislocated. During the construction process, the temporary support rods 7 fix the position of the inner wall body 2, thereby improving the firmness of the overall inner partition wall structure formed after the multiple inner wall bodies 2 are connected, reducing the probability of cracking of the inner partition wall, and ensuring the overall construction quality and thermal insulation performance of the inner partition wall.
