Description
Technical field
The present invention relates to the interconnection technique field of fabricated construction, in particular to a kind of sawtooth clutch lead screw anchors spherical surface spiral shell
Female deviation rod piece connector.
Background technique
Current fabricated construction has become a kind of new industry in China, but the connection to fabricated construction
Whether safe and reliable, whether fabricated construction improves efficiency conscientiously, whether really accelerates speed, improves in much degree
But there are many disputes in environment etc. etc.；During fabricated construction assembly, it is fixed on common on two butting members
The deviation that reinforcing bar, deformed bar and other rod pieces occur in docking in allowed band is unavoidable, this right to adapt to
Deviation is connect, grout sleeve connection, anchor slurry is mostly used to overlap and modes, these connection sides such as connect and be connected by screw bolts greatly at present
Formula all has that complicated construction technique, occupied space are big, can not detect, acceptance criteria is unknown, waiting time for reaching intensity is longer
Etc. drawbacks.
Such as the prefabricated components steel bar connecting structure of famous Peikko company, Finland, by a pre-buried band edge face angle,
Again by side reinforcing bar with being weldingly fixed on the angle steel, while the aperture on the end face, then other side reinforcing bar is passed through into the end face
The fixed mode of blending bolt realizes connection；Although band deviation that this method also achieves butting rod piece connects, but angle used
Steel occupied space is very big, and stress is not direct enough, and dock number of steel bars it is more when, the installation and tightening of angle steel, bolt is compared
It is complicated, so more difficult be widely applied, only using more in the small square column connection of industrial premises.
Summary of the invention
