Embodiment 1

[0038] see figure 1 with figure 2 , figure 1 It shows an exemplary schematic diagram of the vertical joint connection structure of the assembled integral concrete shear wall structure according to the first embodiment of the present invention, figure 2 An exemplary schematic view of the first embedded part and the second embedded part according to the first embodiment is shown.

[0039] The first component 11 is a cast-in-place edge component, and the second component 12 is a prefabricated wall. A post-cast joint 13 with a width of about 50 mm is left before the cast-in-place edge component and the prefabricated wall. The first embedded part 14 and The second embedded part 15 adopts an insertion type node connection. Such as figure 1 with figure 2 As shown, the first embedded part 14 is a U-shaped slot, which is anchored to the surface of the first member 11 to be connected by the first anchor rib 141. The height direction of the U-shaped card slot is set along the le...

Embodiment 2

[0042] see image 3 with Figure 4 , image 3 It shows an exemplary top view schematic diagram of the vertical joint connection structure of the assembled integral concrete shear wall structure according to the second embodiment of the present invention, Figure 4 It shows an exemplary vertical schematic diagram of the vertical joint connection structure of the assembled integral concrete shear wall structure according to the second embodiment of the present invention.

[0043] The first component 11 is a cast-in-place edge component, and the second component 12 is a prefabricated wall. A post-cast joint with a width of about 50 mm is left between the cast-in-place edge component and the prefabricated wall. The first embedded part 14 and the second The two embedded parts 15 are connected by an interlocking node. Such as image 3 with Figure 4 As shown, the first embedded part 14 includes a distance bracket 141 fixed on the side to be connected of the first member 11 and ...

Embodiment 3

[0045] see Figure 5 , Figure 5 It shows an exemplary perspective view of the vertical joint connection structure of the assembled integral concrete shear wall structure according to the third embodiment of the present invention.

[0046] The first component 11 is a cast-in-place edge component, and the second component 12 is a prefabricated wall. A post-cast joint with a width of about 50 mm is left between the cast-in-place edge component and the prefabricated wall. The first embedded part 14 and the second The two embedded parts 15 are connected by an interlocking node. Such as Figure 5 As shown, the first embedded part 14 is a first connecting plate fixed on the side to be connected of the first member 11, and the first connecting plate can be a steel plate, which is arranged along the height direction of the first member on its to-be-connected side. The surface on one side, and the first connecting plate and the surface to be connected of the first member are perpend...

Abstract

The invention discloses a vertical joint connecting structure and method of an assembled monolithic concrete shear wall structure. The connecting structure comprises a first embedded part fixed to theto-be-connected side of a first component, and a second embedded part fixed to the to-be-connected side of a second component, wherein the second embedded part and the first embedded part are fixed,and a post-poured joint with a certain width is formed between the to-be-connected side of the first component and the to-be-connected side of the second component. By adopting the connecting mode, the machining difficulty of the prefabricated components in a factory is lowered, the component machining cost is saved, steel bar binding construction of a construction site is simplified, meanwhile wall body mounting and connection are easy and convenient, the construction efficiency is high, and the comprehensive benefits are good.

Description

technical field [0001] The invention relates to an assembled integral shear wall structure, in particular to an assembled integral concrete shear wall structure vertical seam connection structure and a connection method in which the vertically distributed steel bars are not connected. Background technique [0002] At present, the prefabricated shear wall structure generally adopts the construction method of prefabricating the middle wall and casting the edge components. In the traditional method, at the position of the vertical joint between the prefabricated wall and the edge components, the horizontally distributed steel bars of the middle wall are thrown out and anchored into the edge component area. This connection method has problems such as a large amount of reinforcement on the side of the prefabricated components, a large number of reinforcements in the area of ​​​​the cast-in-place edge components, and low construction efficiency. Contents of the invention [000...
