Description

Stacked Shear Wall

technical field

The utility model relates to the technical field of shear wall structures, in particular to a superimposed shear wall.

Background technique

Shear walls are an important part of prefabricated high-rise and super high-rise concrete buildings. At present, prefabricated shear walls at home and abroad mainly adopt two methods, namely full-section prefabricated reinforced concrete shear walls and double-sided superimposed shear walls. Among them, the double-sided superimposed shear wall is more and more used because of its good structural performance and low manufacturing cost.

Traditionally, a double-sided laminated shear wall is composed of a first wall panel, a second wall panel, and a steel skeleton connected between the first wall panel and the second wall panel. There are two commonly used forming and manufacturing methods: one is to first make two pieces of steel mesh and connecting ties, and then pour the first wall panel and the second wall panel in turn by turning over; However, the size of a single double-sided superimposed shear wall cannot be very large, which will affect the construction efficiency of prefabricated concrete buildings, and this manufacturing method will use a large amount of steel, and the on-site welding workload is large, resulting in high manufacturing costs; another The first is to make two pieces of steel mesh separately, and one of the pieces of steel mesh has a steel truss or connecting tie bars, first pour the first wall panel, and then wait for the second wall panel to be poured before the initial setting. Reinforced trusses or connecting tie bars are pressed into the concrete of the second wall panel, so that the two wall panels can be pulled together into one. However, the depth of the steel truss or connecting tie bars pressed into the second wall panel is limited, and the steel bars of the two wall panels are not connected, so the bending stiffness of the double-sided laminated shear wall after forming is poor, and the structural stability and reliability are poor. weak.

Utility model content

Based on this, it is necessary to provide a composite shear wall, which aims to solve the problems of limited molding size, high manufacturing cost and structural reliability in the prior art.

Its technical solutions are as follows:

The application provides a composite shear wall, which includes:

a first prefabricated wall panel, the side of the first prefabricated wall panel is provided with a first steel bar truss, and the end of the first prefabricated wall panel is provided with a first end member; and

A second prefabricated wall panel, the side of the second prefabricated wall panel is provided with a second steel bar truss, and the end of the second prefabricated wall panel is provided with a second end member; wherein, the first prefabricated wall panel is The second prefabricated wall panel is arranged in parallel and spaced apart to form a pouring cavity, the first steel truss and the second steel truss are both located in the pouring cavity and are arranged horizontally overlapping, the first prefabricated wall plate The other end away from the first end member is spliced and fixed with the second end member, and the other end of the second prefabricated wall panel away from the second end member is spliced and fixed with the first end member , a concrete body connected with the first steel truss and the second steel truss is formed in the pouring cavity.

During the construction of the above-mentioned superimposed shear wall, the first prefabricated wall panel and the second prefabricated wall panel are first prefabricated in the factory, and during the forming and manufacturing process of the first prefabricated wall panel, the first steel bar truss and the first end are simultaneously processed and formed. The first prefabricated wall panel, the first reinforced truss and the first end member are formed into a whole; in the same way, the second prefabricated wall panel, the second reinforced truss and the second end member are also formed according to the same method. as one. After that, the first prefabricated wall panel and the second prefabricated wall panel can be transported to the construction site, so that the first prefabricated wall panel and the second prefabricated wall panel are spliced oppositely. The two prefabricated wall panels and the second end member are enclosed and form a pouring cavity in the middle. The first steel truss and the second steel truss are located in the pouring cavity and are arranged in a longitudinally overlapping manner. Finally, concrete slurry is poured into the pouring cavity. After curing and solidification, a concrete body is formed, and the concrete body is firmly integrated with the first steel truss and the second steel truss. Compared with the traditional manufacturing method and forming structure, the superimposed shear wall of this scheme is prefabricated in the factory because the main components such as the first prefabricated wall panel, the second prefabricated wall panel, the first reinforced truss, and the second reinforced truss are all prefabricated in the factory. It only needs to be transported to the construction site for simple assembly and pouring of concrete, which can greatly reduce the workload of on-site welding, reduce the difficulty and cost of manufacturing; and the first prefabricated wall panel and the second prefabricated wall panel can not be affected by the concrete construction process. Therefore, the size can be very large, which can reduce the number of wall panels splicing, thereby improving the construction and forming efficiency of prefabricated concrete buildings. In addition, since the first steel truss and the second steel truss are horizontally staggered, during the concrete pouring stage, the prefabricated wall panel and its self-contained steel truss have strong bending stiffness, which can effectively resist the prefabricated wall panel before the cast-in-place concrete sets. After the cast-in-place concrete condenses to form the strength, the staggered reinforced trusses can form an enclosure in the cast-in-place concrete cavity, further enhancing the synergy between the prefabricated wall panel and the cast-in-place layer. In addition, the splicing of the first prefabricated wall panel and the second end member, as well as the second prefabricated wall panel and the first end member, can also improve the structural strength and stability of the superimposed shear wall to a certain extent, so that the superimposed shear wall can be finally It has better structural mechanical properties and reliability.

During the construction of the above-mentioned superimposed shear wall, the first prefabricated wall panel 10 and the second prefabricated wall panel 40 are first prefabricated in the factory, and during the forming and manufacturing process of the first prefabricated wall panel 10, the first steel truss 20 is simultaneously processed and formed. and the first end member 30, the first prefabricated wall panel 10, the first steel truss 20 and the first end member 30 are formed into one body; similarly, the second prefabricated wall panel 40, the second prefabricated wall panel 40, the second prefabricated wall panel 40, the second The rebar truss 50 and the second end member 60 are integrally formed. After that, the first prefabricated wall panel 10 and the second prefabricated wall panel 40 can be transported to the construction site, so that the first prefabricated wall panel 10 and the second prefabricated wall panel 40 can be spliced oppositely. The end member 30 , the second prefabricated wall panel 40 and the second end member 60 are surrounded by and form a casting cavity 70 in the middle.
