Description

Technical Field

[0001] The utility model relates to a seam-stretching plate and a full cast-in-place concrete non-stress-bearing structural wall structure. Background Art

[0002] In traditional residential buildings, the building's outer structure usually adopts a construction method that combines shear walls and masonry infill walls. Although this method meets the structural requirements to a certain extent, it has disadvantages such as long construction period, low construction efficiency and many quality problems. In particular, cracks and leakage often occur at the junction of shear walls and masonry infill walls.

[0003] In order to overcome these defects, a new technology - all-in-situ cast-in-place concrete non-stress-bearing structural exterior wall - has emerged in recent years. This technology combines the non-stress-bearing structural concrete exterior wall and the stress-bearing shear wall by casting in one go, effectively avoiding the cracking and leakage problems of the exterior wall. However, since the shear wall and the structural exterior wall are cast in one go, this leads to an increase in structural stiffness, which is inconsistent with the current seismic design concept and has a certain adverse effect on the safety of the structure.

[0004] In order to solve this problem, the industry generally adopts the method of adding a PVC or other elastic material seam plate at the intersection of the shear wall, floor slab and structural concrete wall. This seam plate can effectively offset the rigidity generated by the structural exterior wall and meet the requirements of earthquake-resistant design.

[0005] However, the currently used seam panels often have complex shapes, various connection slots, high production costs, and need to be distinguished between horizontal and vertical forms. On-site installation requires the insertion of fixed steel bars, which is complicated for workers to operate, has many installation procedures, and complex processes, resulting in low construction efficiency, extended construction period, and affected construction quality. Utility Model Content

[0006] The first purpose of the utility model is to provide a seam-drawn plate which simplifies the construction process, reduces the cost, and significantly improves the earthquake resistance of the structure and the anti-leakage performance of the exterior wall.

[0007] The second object of the utility model is to provide a fully cast-in-place concrete non-stress-bearing structural wall structure that meets the requirements of structural earthquake resistance and external wall anti-seepage and anti-leakage.

[0008] The first purpose of the utility model is achieved in this way:

[0009] A seam plate of a fully cast-in-place concrete non-stress structural wall structure, comprising a seam plate main board, both sides of which are provided with water-cutting fixing grooves for fixing and water-cutting functions and a plurality of wire binding holes for fixing the seam plate, and the spacing between two adjacent wire binding holes is 200 mm;

[0010] The inner cavity of the main plate of the seam-pulling board is a hollow cavity, and the inner cavity of the main plate of the seam-pulling board is provided with a stiffening plate for improving the compressive strength of the seam-pulling board;

[0011] The upper and lower sides of the main plate of the seam-drawn board are provided with outwardly inclined ears for improving the connection and fixation between the seam-drawn board and the concrete;

[0012] The length of the main board of the seam board is 150 mm.

[0013] Simplified design, reduced cost: The seam board in this patent is made of PVC-U material, which has high strength and durability. Compared with the traditional complex seam board, the simple design significantly reduces the manufacturing cost.

[0014] Convenient construction and improved efficiency: The seam-drawn plate adopts the method of fixing the slot and tying with wire, without the need for additional fixing steel bars, which greatly simplifies the on-site construction steps. The spacing of the tying holes is 200mm, which optimizes the tying operation, is easy for workers to operate, and the installation process is fast and efficient, which improves the construction efficiency and shortens the construction period.

[0015] Enhanced compressive strength: The inner cavity of the main board of the seam board is a hollow cavity, and the built-in stiffening plate design effectively improves the compressive strength of the seam board, ensuring that it has sufficient structural stability and durability during use.

[0016] Optimize the connection and improve the structural performance: The upper and lower sides of the main board of the seam plate are designed with outward inclined ears, which enhances the connection and fixing effect between the seam plate and the concrete. This design ensures the weak connection between the non-stressed structural wall and the shear wall, meets the requirements of the structural seismic performance, and effectively prevents leakage and cracking of the exterior wall.

[0017] Size control to ensure quality: The length of the main board of the seam board is 150mm. Through precise size control, the thickness of the concrete protective layer at the joint is guaranteed, the risk of cracking is reduced, and the anti-seepage and anti-leakage performance of the exterior wall is further improved.

[0018] The second purpose of the utility model is achieved in this way:

[0019] A fully cast-in-place concrete non-stress-bearing structural wall structure of a seam-drawn plate, further comprising a structural plate, a shear wall and a concrete structural wall, wherein the concrete structural wall is arranged on the structural plate, and the seam-drawn plate is arranged in a horizontal state between the structural plates;

[0020] The shear wall is arranged on the structural plate, and the vertically-oriented seam plate is arranged between the shear wall and the concrete structural wall.

[0021] Stable structure: By setting up concrete structural walls and shear walls on the structural plate, and setting horizontal and vertical seam plates between them, the overall structural stability of the building can be effectively enhanced. As a weak connection part, the seam plate can achieve flexible deformation and energy dispersion of the structure under the action of external forces such as earthquakes, thereby improving the seismic performance of the building.

[0022] Prevent cracks: Horizontal seam panels can effectively alleviate the horizontal deformation of the structure and reduce the cracks caused by structural contraction or thermal expansion and contraction. Vertical seam panels help reduce cracks in the vertical direction and improve the overall sealing and durability of the structure.

[0023] Convenient construction: The setting of the seam plate not only makes the connection between the structural plate, concrete structural wall and shear wall tighter, but also simplifies the construction process. The horizontal seam plate and the vertical seam plate can be installed at the corresponding positions respectively, which is easy to operate and effectively improves the construction efficiency.

[0024] Easy maintenance: Due to the presence of the seam plate, when the building is displaced or deformed due to external reasons, the mutual influence between the structural plate, concrete structural wall and shear wall can be reduced, reducing the cost and difficulty of maintenance and repair.

[0025] Optimize space utilization: The design of the seam board takes into account the structural deformation in different directions and is reasonably distributed on the structural board, which not only meets the structural requirements but also optimizes the space utilization efficiency to the greatest extent.

[0026] The beneficial effects of the utility model are as follows:

[0027] The utility model, the seam plate design not only simplifies the construction process and reduces the cost, but also significantly improves the seismic performance of the structure and the anti-leakage performance of the exterior wall. It is an efficient, economical and reliable solution for the seam plate of the fully cast-in-place concrete non-stress-bearing structural wall structure.

[0028] The utility model provides a fully cast-in-place concrete non-stress-bearing structural wall structure of the seam-pulled plates, and by reasonably arranging the seam-pulled plates in horizontal and vertical states, the building structure is made more stable and durable, and also the construction efficiency and maintenance convenience are improved.
