A kind of shear-wall strengthening part and its preparation process
Technical field
The present invention relates to construction equipment technical fields, more particularly to a kind of shear-wall strengthening part and its preparation work
Skill.
Background technique
With the development of building trade, high-rise and frame structure building is increasing, due to high shock resistance energy, strong waterproof
The demand of performance, most of building mostly use the mode of cast-in-place concrete to be built, before being poured concrete, need building
Shear wall precast frame is built on building site, and precast frame is reinforced using shear-wall strengthening part.Most of building at present
In shear-wall strengthening part still use the traditional technologies such as screw rod and nut to realize, when being reinforced using screw rod and nut,
First by the prefabricated frame of screw rod insertion shear wall, the both ends of screw rod are located at the two sides of shear wall precast frame, then exist
The both ends of screw rod respectively penetrate fastener, finally install bolt at the both ends of screw rod, the bolt at both ends is screwed inwardly into and is close to buckle
Fastener is close to shear wall precast frame, is achieved in the reinforcing to shear wall precast frame by part.However use screw bolt and nut
