Embodiment 1

[0079] Embodiment 1, a ring-reinforced fastening and anchoring assembled shear wall composite structure system, including vertical component connections and horizontal component connections, such as figure 1 with 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, There is a truss reinforcement 2-3 connection between the two thin shear walls 1-1, and the internal reinforcement of the two thin shear walls 1-1 is a closed circular reinforcement, and the exposed concrete surface around the closed circular reinforcement is a circular anchor reinforcement 2-2 . Such as figure 1 As shown, the vertical butt joint surfaces on both sides of the hollow prefabricated composite concrete shear wall 1 are provided with several annular anchoring reinforcement bars 2-2, s...

Embodiment 2

[0083] Embodiment 2, an installation method of a ring-bar fastening and anchoring assembled shear wall composite structure system, 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:

[0084] Step 1: If Figure 4 As shown, install the hollow prefabricated laminated concrete shear wall 1 on the lower floor, and pour concrete 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 or poured to the thin shear wall 1-1 top.

[0085] Step 2: Horizontally hoist the prefabricated floor slabs 3 on both sides of the hollow prefabricated laminated concrete shear wall 1 described in step 1, so that the anchor bars 2 on the upper part of the hollow prefabricated laminated concrete shear wall 1 in the lower layer described in step 1 are hoisted horiz...

Embodiment 3

[0099] Embodiment 3, an installation method of a ring-reinforcement anchorage assembled shear wall composite structure system, the T-shaped connection includes the method of T-shaped external ring-reinforcement buckle and the method of T-shaped direct buckle, and the T-shaped connection The legality of the outer ring rib buckle is as follows Figure 12 shown, including the following steps:

[0100] 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.

[0101] 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 reinforcement are respectively lapped on the annular anchoring rein...

Abstract

The invention discloses a circular bar buckling and anchoring assembly type shear wall composite structure system and an installation method. The circular bar buckling and anchoring assembly type shear wall composite structure system comprises vertical member connection and horizontal member connection, wherein a vertical member and a horizontal member respectively comprise a hollow prefabricatedcomposite concrete shear wall and a prefabricated composite floor slab; the hollow prefabricated composite concrete shear walls are mutually connected by a circular anchoring reinforcing steel bar; the prefabricated floor slab is horizontally connected to the top end of the hollow prefabricated composite concrete shear wall at each floor; each hollow prefabricated composite concrete shear wall comprises two symmetrical thin shear walls; a long reinforcing steel bar penetrates through each thin shear wall to form a sealed circular reinforcing steel bar; the part, exposing out of the surroundingsurfaces of the concrete, of each sealed circular reinforcing steel bar is a circular anchoring reinforcing steel bar; circular anchoring reinforcing steel bars or straight bars are arranged around each prefabricated floor slab and are buckled with each hollow prefabricated composite concrete shear wall. The circular bar buckling and anchoring assembly type shear wall composite structure system has the advantages that the operation is simple, the construction efficiency is high, the integrity, earthquake-proof property and waterproof property are good, and the popularization and application prospect is good.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a superimposed structure system and installation method of an assembled shear wall with buckling and anchoring of ring bars. 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 reinforcement buckled concrete shear wall structure is connected, the existence of construction joints seriously affects the waterproof performance and integrity of the structure. Contents of the invention [0003] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a composite structure system and installation method of an as...
