Abstract

The utility model discloses a rebar structure of a prefabricated component. The rebar structure comprises a first stirrup, a second stirrup, a horizontal rebar, a prefabricated section and a cast-in-situ section, wherein the first stirrup and the second stirrup are placed in parallel and separated by a certain distance; draw knots are arranged at the two ends of the horizontal rebar; the horizontal rebar is vertically intersected with the first stirrup and the second stirrup; the first stirrup and the second stirrup are provided with prefabricated stretching sections; the stretching sections are arranged in the prefabricated section and are used for prefabricating an edge component; a combined structure of the horizontal rebar, the first stirrup and the second stirrup is arranged in the cast-in-situ section. According to the rebar structure disclosed by the utility model, the horizontal stirrups stretching from the prefabricated section are drawn to form a whole by the horizontal rebars of the two ends are tied with one another so as to approach to the stress property of a whole cast-in-situ shear wall structure; the vertical rebar in the connection section penetrates up and down to form a cast-in-situ embedded column, and the integrity is enhanced.

Description

The bar construction of prefabricated units

Technical field

The utility model relates to the bar construction of prefabricated units, relates in particular to the bar construction of prefabricated units of the on-the-spot colligation of building operations.

Background technology

At present building operations adopts on-the-spot cast-in-place mode substantially, on-the-spot by artificial assembling reinforcement, install template after-pouring concrete, expend a large amount of artificial, timber and water resource, and environment caused to very large pollution; Assembled-type house structure is as a kind of new structure system, after a large amount of members have been prefabricated in the factory, being transported to scene installs, greatly reduce on-the-spot artificial and wet trade amount, improved construction quality, effectively reduced the building energy consumption of work progress and later stage use; But current binding reinforcing bars mode cannot meet the requirement of house globality and shock resistance, and under linkage section and the cast-in-place state of edge member, the reinforcing bar binding of prefabricated units junction is more difficult.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, joint connection in site prefabricated units reinforcing bar connection easily, can effectively realize the whole anti-seismic performance of house.

The utility model comprises the first stirrup, the second stirrup, horizontal reinforcement, prefabricated section and Cast-in-Situ Segment; Described the first stirrup and the second stirrup are placed side by side, and between the first stirrup and the second stirrup in a distance; The two ends of described horizontal reinforcement are provided with drawknot, and described horizontal reinforcement and the first stirrup, the second stirrup square crossing arrange; Described the first stirrup, the second stirrup are provided with the prefabricated section of stretching out; The described section of stretching out is arranged in prefabricated section, for prefabricated edge member; Described horizontal reinforcement, the first stirrup, the second stirrup be combined into one structure, and be arranged in Cast-in-Situ Segment.

Between described the first stirrup and the second stirrup, distance L is apart 140mm.

Described Cast-in-Situ Segment is T-shaped shear wall.

Left side drawknot and first stirrup of described horizontal reinforcement link together; Right side drawknot and second stirrup of described horizontal reinforcement link together; Described horizontal reinforcement, the first stirrup, the second stirrup form integrative-structure.

The integrative-structure that described horizontal reinforcement, the first stirrup, the second stirrup form is vertically arranged in Cast-in-Situ Segment.

The bar construction of the utility model prefabricated units, utilize the horizontal reinforcement of the mutual drawknot in two ends that the prefabricated section of horizontal hoop drawknot stretching out formed to integral body, to reach the stress performance that approaches integral cast-in-situ formula shear wall structure, its middle connecting segment vertical reinforcement up/down perforation, form cast-in-place sleeper, strengthen globality; Wall between windows place end edge member and window frame are integral prefabricated, sealing, the water resistance of exterior window have been improved, when shorter wall between windows is prefabricated, outside need not be done concrete outer wall template again, and middle cast-in-place linkage section reinforcing bar connects to be simplified, and has improved reliability and the efficiency of on-the-spot colligation.
