[0002] When aluminum alloy formwork is used in the main structure stage of construction, its high rigidity and strong plasticity are utilized to bring out the masonry structure of the outer wall opening with concrete structure at one time during the construction process. However, this may cause cracks in places such as the wall under the window due to concrete shrinkage.

[0003] The invention patent with patent application publication number CN110424564A discloses a joint connection structure of the exterior wall of an assembled building, including a first exterior wall and a second exterior wall, the top and side end surfaces of the first exterior wall and the second exterior wall are both provided with connecting grooves, a joint is arranged between the first exterior wall and the second exterior wall, a joint connection structure is installed inside the joint, the first exterior wall and the second exterior wall are connected through the joint connection structure, in this invention, a joint is arranged between the first exterior wall and the second exterior wall, a joint connection structure is arranged inside the joint, a first L-shaped bracket and a second L-shaped bracket are respectively arranged on both sides of the joint connection structure, the joint connection structure is connected to the connecting grooves on the first exterior wall and the second exterior wall through the connecting blocks on the first L-shaped bracket and the second L-shaped bracket, so that the joint connection structure is completely independent of the first exterior wall and the second exterior wall, and can be disassembled while ensuring the connection effect, so as to facilitate the later maintenance and disassembly of the wall.

[0004] However, in the above scheme, in order to prevent the occurrence of concrete cracks at the nodes of the wall under the window and the surrounding shear wall of the all-concrete exterior wall, anti-cracking steel bars must be added transversely to the wall under the window, the lower hanging plate, and the anti-slope. The anti-cracking steel bars are extended into the shear wall. At the same time, constructing some masonry structures, such as the wall under the window, into concrete structures will increase the overall stiffness of the structure. The wall under the window and the shear wall are flexibly connected to separate the non-structural body from the structural body, thereby reducing the overall stiffness of the structure. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. In order to overcome the above-mentioned defects of the prior art, the present invention provides a construction method for node treatment at the joint of the structural wall under the window and the shear wall, so as to solve the problem proposed in the above-mentioned background technology that constructing a concrete structure at a position such as the wall under the window will increase the stiffness of the entire structure.

[0018] Technical effects and advantages of the present invention:

[0019] 1. The present invention adopts a horizontal structural seam assembly between a floor slab and a structural wall under a window installed at a floor slab or a beam position before the initial setting of concrete, a vertical structural assembly is arranged between the shear wall and the structural wall after the steel bars are tied, and anti-cracking steel bars are arranged between the structural wall and the shear wall, the steel bars also have the function of fixing the vertical structural assembly of the structure, the anti-cracking tie steel bars pass through the vertical structural assembly and are tied and overlapped with the steel bars of the walls on both sides, so that the connection tightness of the node at the joint of the structural wall under the window and the shear wall can be increased during the construction process, so that not only will cracking not be caused after forming, but also the strength of the node at the joint of the structural wall under the window and the shear wall is improved;

[0020] 2. The first layer of the present invention should not be poured at a height of more than 500mm, and each subsequent pouring height should not exceed 1.0m. When vibrating the second layer of concrete, the vibrating rod should be extended into the upper layer of concrete, so that the newly poured concrete is well combined with the poured concrete. Before pouring the concrete, a layer of mortar with a thickness of -mm and the same composition as the original concrete is poured on the bottom layer. When constructing the node treatment at the joint of the structural wall and the shear wall under the window, ensure that the concrete is constructed in layers to avoid excessive concrete pressure at one time, causing the bottom to expand out, and ensure that each layer of concrete is more firmly combined, has better stability, and is not prone to leakage.

[0021] 3. The present invention adopts a vertical structure seam assembly and a horizontal structure seam assembly. When the node treatment construction is carried out at the joint of the structural wall under the window and the shear wall, two beam brackets can be formed and welded at the upper position of the two limit support templates, and the embedded screws are embedded in the shear wall. The vertical cross-bracing plate is fixed at the connection of the shear wall, and is inserted into the cross-bracing plate and the vertical cross-bracing plate by embedding the positioning support block, so as to ensure that the vertical cross-bracing plate is not easy to deviate when installed on the shear wall. The second locking bolt is used to realize the relative extrusion of the alignment locking support plate and the embedded pull plate. The positioning nut can position and lock the position of the first horizontal cross-bracing plate to ensure the firmness of the first horizontal cross-bracing plate after tightening, forming a horizontal and vertical double tightening gap, showing tightening in different directions, improving the binding tightness of the joint position, and the concrete is more tightly and firmly fitted with the shear wall after forming;

[0022] In summary, through the mutual influence of the above-mentioned multiple effects, the tightness of the connection between the nodes at the joints of the structural wall under the window and the shear wall can be increased during the construction process, so that not only will cracks not be caused after molding, but the binding tightness of the joint position is improved, and the concrete fits more tightly and firmly with the shear wall after molding. In summary, the strength of the nodes at the joints of the structural wall under the window and the shear wall can be improved. After molding, the firmness is better, it is not easy to cause water seepage problems, it will not cause concrete cracks, and the construction stability is higher. BRIEF DESCRIPTION OF THE DRAWINGS

After the reinforcement is tied, set the vertical structural component between the shear wall and the structural wall, and set the anti-cracking reinforcement between the structural wall and the shear wall. The anti-cracking reinforcement is of HRB335 grade. The diameter of the anti-cracking reinforcement is five centimeters and it is fixed by cross weaving. The reinforcement also has the function of fixing the vertical structural component of the structure.
