The member that described precast unit horizontal reinforcement connects, the stirrup anchoring that described L shaped reinforcing bar and described L shaped reinforcing bar are down placed with described top after on-the-spot straightening, described L shaped reinforcing bar and the described time L shaped reinforcing bar partly is connected to each other with the embedded bar of described both sides after on-the-spot straightening, is reserved with certain handing-over space therebetween.
The member that described precast unit horizontal reinforcement connects inserts vertical elongated reinforcing bar in the handing-over space described between L shaped reinforcing bar and described L shaped reinforcing bar down and the described stirrup and forms sleeper.
The side that the member that described precast unit horizontal reinforcement connects, described precast unit body carry out the horizontal direction connection mutually is prefabricated into gingival cyst of mucous gland in the newborn stubble shape.
A kind of connection job practices of precast unit horizontal reinforcement connecting elements, the method of attachment of precast unit horizontal reinforcement, the inside of precast unit body is one to one pre-buried, be respectively L shaped reinforcing bar and following L shaped reinforcing bar, go up L shaped reinforcing bar and pre-buried end fully anchoring in precast unit of L shaped reinforcing bar down, it is external that the L shaped shape reinforcing bar of last L shaped reinforcing bar that exposes and following L shaped reinforcing bar partly stretches out precast unit, the L shaped shape reinforcing bar part of the pre-buried bending of its correspondence overlaps the upper back mutually and places stirrup after on-the-spot straightening, in stirrup, insert vertical elongated reinforcing bar and form sleeper, with the abundant anchoring of horizontal reinforcement, be reserved with certain handing-over space therebetween, handing-over is inserted vertical elongated reinforcing bar in the space, both sides install template before and after the junction afterwards, from the upper pouring concrete, after maintenance, two precast units are connected into integral body.
Beneficial effect:
1. what the present invention realized is the method for attachment of assembling shear wall structure precast unit horizontal reinforcement, do not need a large amount of reinforcing bar welding and mechanical connection program, only needing simple manual assembling reinforcement can finish horizontal reinforcement connects, characteristics are built in the construction that is particularly suitable for housing industrialization (assembling) precast concrete of energy-conserving and environment-protective, be the once great revolution of adhering to industry, for the Ministry of Construction, Beijing, the decision project verification of test back, Shanghai City prepare to promote.
The present invention can make the horizontal reinforcement of the junction between assembling shear wall structure precast unit keep continuously, the reinforcing bar that can be up to the standard transmits the effect of load opposing shearing force, because it is the gingival cyst of mucous gland in the newborn stubble that member designs continuous recessed stubble at the interface, interface shear stress between transmission member fully can ensure the overall performance of connected precast unit fully after therefore connecting.
The present invention makes connected precast unit have enough lap length, forms constructional column assurance reliability of structure by stretch into the closed stirrup of setting up on horizontal reinforcement.
Construction technology of the present invention is simple, do not need complicated mechanical equipment and facility and power consumption in the work progress; Greatly improved precast unit and assembled speed of application in the building site, saved the duration, construction quality is easy to guarantee, the building course environmental protection and energy saving, reduced cost, saves construction fund.
The present invention is simple to operate, just by factory process concrete component, lifting back and carry out the installation that simple filling process can be finished precast unit at the scene.
The present invention can make assembling shear wall structure precast unit be beneficial to plant produced processing.
