[0009]Compared with the prior art, the beneficial effects of this utility model are as follows: A connection structure between the main structural shear wall and the cast-in-place structural wall uses tubular connectors instead of traditional extruded polystyrene boards in the lateral direction of the concrete side window pouring area. The connectors isolate the concrete side window pouring area and the shear wall. After construction, the tubular connectors can achieve the same isolation and fixing effect as extruded polystyrene boards and increase the overall rigidity of the combined cast-in-place exterior wall and the main structural shear wall. At the same time, the tubular connectors are easier to fix during construction, and the vibration of concrete during reinforcement binding and subsequent pouring has less impact on their fixing position, making it less likely for the connectors to shift. Using this connection structure to connect the shear wall and the cast-in-place structural wall can effectively simplify the construction steps, reduce the operation difficulty, and improve the construction efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, specifically to a connection structure between the main structural shear wall and the cast-in-place structural wall. Background Technology
[0002] The monolithic casting technology for fully cast-in-place exterior walls utilizes aluminum formwork construction, achieving one-time casting and effectively avoiding problems such as cracks and leaks in the exterior walls, reducing wet work processes, and improving efficiency. However, to improve the overall stiffness of the combined structure between the fully cast-in-place exterior wall and the main structural shear wall, and to make the completed structure safer, a connection structure is needed between the main shear wall structure and the fully cast-in-place wall. Traditional connection structures mostly use extruded polystyrene (XPS) boards to separate the main shear wall structure from the fully cast-in-place wall in the lateral direction. XPS boards are difficult to fix in the lateral direction, and the vibration of concrete during rebar tying and subsequent pouring has a significant impact on the lateral XPS boards, making it difficult to ensure the stability of the fixed position. This not only increases construction difficulty but also affects the overall stiffness of the combined fully cast-in-place exterior wall and the main structural shear wall. Therefore, we propose a connection structure between the main structural shear wall and the cast-in-place structural wall. Utility Model Content
[0003] The purpose of this utility model is to provide a connection structure between the main structural shear wall and the cast-in-place structural wall, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a connection structure between a main structural shear wall and a cast-in-place structural wall, comprising a shear wall and a concrete side window casting area, wherein structural components are fixedly assembled between the shear wall and the concrete side window casting area, and connecting components are fixedly assembled between the shear wall and the concrete side window casting area in a left-right symmetrical manner.
[0005] Preferably, the connector is a PVC pipe with a diameter of 75mm.
[0006] Preferably, the structural component includes a fixing bar, which is vertically and uniformly fixed between the shear wall and the concrete side window pouring area. The upper half of the fixing bar is symmetrically fixed with U-shaped inner fasteners on the left and right, and the lower half of the fixing bar is fixed with double-end inner fastener connecting pieces.
[0007] Preferably, a window opening reinforcing rib is fixedly assembled between the U-shaped inner fastener and the double-end inner fastener connecting member.
[0008] Preferably, an extruded polystyrene board is fixedly installed between the bottom of the concrete side window pouring area and the shear wall.

The connectors isolate the concrete side window pouring area and the shear wall. After construction, the tubular connectors can achieve the same isolation and fixing effect as extruded polystyrene boards and increase the overall rigidity of the combined cast-in-place exterior wall and the main structural shear wall. At the same time, the tubular connectors are easier to fix during construction, and the vibration of concrete during reinforcement binding and subsequent pouring has less impact on their fixing position, making it less likely for the connectors to shift.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a connection structure between the main structure shear wall and the cast-in-place structural wall, including a shear wall 1, a cast-in-place concrete side window pouring area 2 embedded in the shear wall 1, a structural component 3 fixedly assembled between the shear wall 1 and the concrete side window pouring area 2, and connectors 4 symmetrically fixedly assembled on the left and right sides of the layer between the shear wall 1 and the concrete side window pouring area 2. By setting connectors 4 to replace the traditional connection structure, the influence of the cast-in-place structural wall on the rigidity of the main structure is avoided when the entire cast-in-place exterior wall is cast as a whole, and at the same time, a reliable connection between the cast-in-place structural wall and the main structure shear wall is achieved.
[0016] The connector 4 is a PVC pipe with a diameter of 75mm. The length of the pipe used needs to be determined according to the size of the concrete side window pouring area 2 to be poured. Using PVC pipe connector 4 is not only cheaper, but also easier to construct than the traditional method of setting extruded polystyrene boards on the side to isolate the concrete side window pouring area 2 from the shear wall 1. It can achieve the purpose of isolating the shear wall 1 from the concrete side window pouring area 2, while also reducing the difficulty of construction, reducing the requirements for construction technology, and effectively improving construction efficiency.
[0017] like Figure 1 As shown, the structural component 3 includes a fixing bar 31 vertically installed in the shear wall 1. The fixing bar 31 penetrates the pouring area of the concrete side window pouring area 2. The upper half of the fixing bar 31 is symmetrically welded with U-shaped inner fasteners 32 on the left and right. The U-shaped inner fasteners 32 are made of bent steel bars. The size between the two U-shaped inner fasteners 32 is the opening size after the concrete side window pouring area 2 is poured. The bottom of the fixing bar 31 is welded with a double-ended inner fastener connecting piece 33. The double-ended inner fastener connecting piece 33 is also made of bent steel bars and is set below the concrete side window pouring area 2. The connecting piece 4 is tied between the U-shaped inner fasteners 32 and the double-ended inner fastener connecting piece 33 by steel wire. The operation is simple and convenient.
[0018] like Figure 1 As shown, window opening reinforcing ribs 34 are welded and fixed between the U-shaped inner fastener 32, the double-ended inner fastener connecting piece 33, and the fixing rib 31. There are 8 window opening reinforcing ribs 34, with four ribs forming a group. The two groups of window opening reinforcing ribs 34 are symmetrically distributed in front and back. In each group, there are two window opening reinforcing ribs 34 on each side, symmetrically distributed on the left and right. By setting the window opening reinforcing ribs 34, the overall strength of the structural component 3 can be strengthened. When the window is assembled after the concrete side window pouring area 2 is poured, it can effectively support the window and prevent the window from deforming due to load during use.
[0019] An extruded polystyrene board 5 is installed between the bottom of the concrete side window pouring area 2 and the shear wall 1. The bottom of the concrete side window pouring area 2 is isolated from the shear wall 1 by the extruded polystyrene board 5. It is easier to implement to install the extruded polystyrene board 5 at the bottom than at the side. The extruded polystyrene board 5 effectively isolates the bottom of the concrete side window pouring area 2 from the bottom of the shear wall 1.
[0020] Working principle: During the construction of shear wall 1, the fixing bars 31 in the structural component 3 are first pre-embedded. Then, the connectors 4 are fixed in the concrete side window pouring area 2. The connectors 4 are symmetrical on the left and right. Then, the extruded polystyrene board 5 is set at the bottom of the concrete side window pouring area 2. Then, according to the setting dimensions of the concrete side window pouring area 2, the U-shaped inner fastener 32 and the double-end inner fastener connecting piece 33 are welded and fixed. The window opening reinforcing bar 34 is welded and fixed between the U-shaped inner fastener 32 and the double-end inner fastener connecting piece 33 to form the integral structural component 3. Subsequently, concrete can be poured into the pouring position of the concrete side window pouring area 2 according to the mold setting to form a fully cast-in-place exterior wall. The use of connectors 4 to replace the traditional connection method can avoid the influence of the cast-in-place structural wall on the stiffness of the main shear wall structure. At the same time, it can realize the reliable connection between the cast-in-place structural wall and the main shear wall structure, making the construction process simpler and improving construction efficiency.
