Description
Technical field
The present invention relates to building element technical fields, and in particular to the skewer pin between a kind of modularization steel construction piece for building
Connection structure.
Background technique
The method that current high-rise building mainly uses cast-in-place concrete, the site operation of structure generally will be by branch
If template, the working procedure for laying reinforcing bar, placing concrete demoulding again.Site operation program and complex management, construction cost compared with
Greatly；Building waste is more, and building yard is not easy to clean；The noise of site operation seriously affects the life and work of surrounding resident,
It is unfavorable for the protection of environment；Due to being influenced by factors such as construction material, weather conditions, field management, quality of workers, scene is applied
Working medium amount is also not readily available guarantee.Using prefabricated building components, the method for joint connection in site building construction structure can overcome
Above-mentioned many defects.However the connection structure that can guarantee securely to connect between each other is needed between prefabricated building components.
In the prior art, patent document CN201738600U and CN104314314A individually discloses this kind of assembled integral
Building comprising upper layer prefabricated components and lower layer's prefabricated components, the bottom embedded bar sleeve of upper layer prefabricated components, reinforcing bar set
An injected hole, the side wall of one end of the separate reinforcing bar entrance of reinforced bar sleeve are provided on the side wall of close reinforcing bar entrance one end of cylinder
On open slurry outlet, the position fixed setting corresponding with steel bar sleeve of lower layer's prefabricated components upper end is adapted to extend into the connection of steel bar sleeve
Reinforcing bar.Reinforcing bar is connected when assembly and injects steel bar sleeve, and cement mortar is injected into steel bar sleeve from injected hole and is solidified, so that upper layer
Prefabricated components are connected with lower layer's prefabricated components.Longitudinally connected reinforcing steel bars exposed on lower layer's prefabricated components of above structure is in component wheel
Except exterior feature, damaged in collision is easy in manufacture and transport, and the width that reinforcing bar increases out is easy ultra-wide but also transporting.
It is easy to scratch operator when installation, there are security risks.Further, reinforcing bar protrudes into set in connection structure in the prior art
