Description

Technical Field

[0001] The utility model relates to a fully cast-in-situ concrete non-stress-bearing structural exterior wall and a main body connection structure. Background Art

[0002] Traditional residential building envelopes primarily utilize a combination of shear walls and masonry infill walls. While widely used, this construction method suffers from long construction times and low efficiency. More seriously, cracking and leakage are common at the interface between the two materials. To address these issues, fully cast-in-place concrete, non-load-bearing exterior walls have emerged and have been widely embraced by the industry in recent years.

[0003] Fully cast-in-place concrete non-load-bearing structural exterior walls are a new technology that combines non-load-bearing structural concrete exterior walls with load-bearing shear walls in a single cast. This technology effectively avoids the quality issues common in traditional construction methods, such as exterior wall cracking and leakage. However, because the shear walls and structural exterior walls are cast in one cast, this method increases structural rigidity, which is inconsistent with current seismic design concepts and has a negative impact on structural safety.

[0004] Currently, a widely adopted solution in the industry is to add elastic joint panels at the junctions of shear walls, floor slabs, and structural concrete walls to offset the stiffness generated by the structural exterior walls. Typically, each fully cast-in-place concrete non-load-bearing structural exterior wall is connected to the main structure by adding both horizontal and vertical joint panels. While this approach effectively alleviates structural stiffness issues, it also increases the number of joint panels and the number of construction steps, thereby reducing construction efficiency. Utility Model Content

[0005] The utility model aims to provide a fully cast-in-situ concrete non-stress-bearing structural exterior wall and main body connection structure, which reduces the number of seam plates and improves construction efficiency.

[0006] The purpose of this utility model is achieved in this way:

[0007] A fully cast-in-place concrete non-stress-bearing structural exterior wall and main body connection structure, comprising a structural plate formwork, a concrete structural wall formwork, a structural main body, and a seam plate. After the structural plate formwork is poured with concrete, the seam plate is pressed into the concrete before the concrete of the structural plate formwork initially sets. After the concrete of the structural plate formwork sets and achieves a water-blocking effect, the structural plate formwork is removed to form the structural plate.

[0008] The concrete structural wall template is arranged between the structural body and the structural plate, and the seam plate enters the concrete structural wall template to tie the steel bars of the concrete structural wall template and the steel bars of the structural body;

[0009] Then, concrete is built in the concrete structural wall formwork. After the concrete in the concrete structural wall formwork is solidified and reaches the water-blocking effect, the concrete structural wall formwork is removed to form the concrete structural wall.

[0010] Reduce the number of joint panels: By installing horizontal joint panels only on the non-load-bearing exterior walls of the fully cast-in-place concrete structure, connecting them to the main structure, the use of vertical joint panels is reduced. This design significantly reduces the total number of joint panels, simplifies the construction process, and reduces construction costs.

[0011] Improved construction efficiency: Since only horizontal seam panels need to be installed, there is no need to add vertical seam panels at the same time, making the construction process simpler and more efficient. This reduces the complexity of the process, thereby improving overall construction efficiency and shortening the construction period.

[0012] Reduced construction costs: The reduction in the number of seam panels directly reduces material costs. In addition, the reduced construction steps also reduce labor costs and the frequency of construction equipment use, further saving the total cost of the project.

[0013] Ensuring Structural Safety: Despite reducing the use of horizontal seams, the design still effectively offsets the stiffness of the exterior walls, ensuring the structure's seismic performance and overall safety are not compromised. Carefully designed horizontal seam placement and quantity minimize the increase in stiffness while maintaining structural safety and stability.

[0014] Prevent cracking and leakage: The fully cast-in-place concrete non-load-bearing structural exterior walls and the main structure are cast in one step, avoiding the common cracking and leakage problems at the material joints in traditional construction methods, and improving the overall quality and durability of the building's exterior structure.

[0015] The purpose of the utility model can also be solved by the following technical measures:

[0016] Furthermore, the structural body is a structural body wall and a structural body column.

[0017] The beneficial effects of the utility model are as follows:

[0018] The utility model improves construction efficiency and economic benefits, and also ensures the safety and durability of the building structure, and has significant practical application value.

[0019] The utility model reduces the use of vertical seam panels by only installing horizontal seam panels on the non-stress-bearing exterior walls of the fully cast-in-situ concrete structure and connecting them to the main structure. This design significantly reduces the total amount of seam panels, simplifies the construction process, and reduces construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

After the structural plate 2 template is poured with concrete, before the concrete of the structural plate 2 template is initially set, the seam plate 3 is pressed into the concrete. After the concrete of the structural plate 2 template is solidified and reaches the water-blocking effect, the structural plate 2 template is removed to form the structural plate 2;

[0024] The concrete structural wall 1 template is set between the structural body 4 and the structural plate 2, and the seam plate 3 enters the concrete structural wall 1 template to tie the steel bars of the concrete structural wall 1 template and the steel bars of the structural body 4;

[0025] Then, concrete is built in the template of the concrete structural wall 1. After the concrete in the template of the concrete structural wall 1 solidifies and reaches the water-blocking effect, the template of the concrete structural wall 1 is removed to form the concrete structural wall 1.

[0026] Furthermore, the structural body 4 is a structural body wall and a structural body column.
