Embodiment 1

[0080] Embodiment 1, a prefabricated shear wall composite structure system that is easy to install, including vertical component connections and horizontal component connections, such as figure 1 and figure 2 As shown, both the vertical and horizontal components include a hollow prefabricated laminated concrete shear wall 1 and a prefabricated floor 3, and the hollow prefabricated laminated concrete shear wall 1 includes two symmetrically arranged thin shear walls 1-1, The two thin shear walls 1-1 are connected by truss reinforcement 2-3. Such as Figure 9 As shown, the vertical butt joint surfaces on both sides of the hollow prefabricated composite concrete shear wall 1 are provided with several shaped anchor bars 2-2 or several bent anchor bars 2-1, and the ends of the bent anchor bars 2-1 The bending angle at the top is 135°.

[0081] Such as Figure 6 As shown, the lower end surface of the hollow prefabricated composite concrete shear wall 1 is arranged side by side w...

Embodiment 2

[0085] Embodiment 2, an installation method of a prefabricated shear wall composite structure system that is easy to install, including vertical component installation and connection and horizontal component installation and connection, the vertical component installation and connection process is as follows Figure 4-8 shown, including the following steps:

[0086] Step 1: If Figure 4 As shown, the hollow prefabricated composite concrete shear wall 1 of the lower layer is installed and fixed, and concrete is poured in the middle of the two thin shear walls 1-1 until the concrete is 10-20cm away from the top of the thin shear wall.

[0087] Step 2: Vertically hoist the prefabricated floor slab 3 so that the bent anchoring reinforcement bars 2-1 on the upper part of the hollow prefabricated composite concrete shear wall 1 described in step 1 and the bent anchoring reinforcement bars 2-1 at the end of the prefabricated floor slab 3 intersecting with each other, such as Figur...

Embodiment 3

[0101] Embodiment 3, an installation method of a prefabricated shear wall composite structure system that is easy to install, the T-shaped connection includes the T-shaped outer loop rib buckle method and the T-shaped direct buckle method, and the T-shaped outer loop Ribbons legal as Figure 12 shown, including the following steps:

[0102] Step 13: hoist the three pages of hollow prefabricated laminated concrete shear walls 1 into place, so that the three pages of hollow prefabricated laminated concrete shear walls 1 form a T-shaped arrangement.

[0103] Step 14: Place ring-shaped steel bars 4 at the butt joints of the three-page hollow prefabricated composite concrete shear walls 1 described in step 13. There are two ring-shaped steel bars 4, and the two ring-shaped steel bars 4 form a T-shaped composite bar. The three ends of the T-shaped composite tendons are buckled respectively on the annular anchoring reinforcement bars 2-2 of the three-page hollow prefabricated lamina...

Abstract

The invention discloses an easy-to-install assembled shear wall composite structure system and an installation method thereof. The technical problem that the existing assembled shear wall structure has the disadvantages of complicated connection of components, difficult construction and poor integrity and waterproof performance is solved. The assembled shear wall composite structure system comprises vertical component connection and horizontal component connection. Both vertical components and horizontal components include hollow prefabricated composite concrete shear walls and prefabricated floor slabs. The hollow prefabricated composite concrete shear walls are horizontally connected and vertically connected. The prefabricated floor slabs are horizontally connected to the top end of thehollow prefabricated composite concrete shear wall on each floor. Each hollow prefabricated composite concrete shear wall includes two symmetrical thin shear walls. Bent anchorage bars buckled to thecorresponding hollow prefabricated composite concrete shear wall are arranged around each prefabricated floor slab. The assembled shear wall composite structure system has the advantages of simple construction, high construction efficiency and good waterproof performance, and has a good popularization and application prospect.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a prefabricated shear wall superimposed structure system and an installation method that are easy to install. Background technique [0002] The prefabricated shear wall structure is a type of prefabricated concrete structure, which is defined as a prefabricated concrete structure in which the shear walls, beams, and slabs of the main force components are partially or entirely composed of prefabricated concrete components. When the traditional prefabricated ring bars are fastened and anchored to the concrete shear wall structure for vertical connection, after the upper and lower walls are in place, the horizontal steel bars need to be penetrated. Every time the horizontal steel bars pass through a certain distance, they will be blocked, requiring workers to carry out time-consuming work. Laborious manual adjustment makes the installation very difficult ...
