Technical field
The utility model is related to a kind of reinforcing bar self-locking connection structure, be mainly used for reinforcing bar and concrete bodies or reinforcing bar with
Between reinforcing bar it is quick, be reliably connected, it can also be used to the connection between bolt and concrete bodies or bolt and bolt.
Background technology
Currently, the fields such as construction are frequently necessary to reinforcing bar being attached with concrete bodies, by reinforcing bar and reinforcing bar.Tradition
Reinforcing bar and bar connecting, mainly have straight screw sleeve connection, welding, cold extrusion sleeve connection, grout sleeve connection etc..These
Connection type is required to larger operating space and a large amount of manual operations, or even operator is needed to have certain professional skill
Can, it is unfavorable for the raising of efficiency.And traditional reinforcing bar connect the mode of being mainly the following with concrete bodies:
One, it beats expansion bolt, punch inserting expansion bolt in concrete bodies, then weld reinforcing bar to be connected;
Two, bar planting, in concrete bodies internal drilling, with structure glue sticking anchor bar;
Three, built-in fitting, pre-embedded steel slab and anchor bar before casting concrete;
Four, embedded bar, the embedded bar before casting concrete.
The connection type of above-mentioned reinforcing bar and concrete bodies has their own advantages, and also suffers from certain drawbacks simultaneously, wherein playing expansion
The switching performance of bolt is poor, is not suitable for long-term stress load;Bar planting then has that cost is high, destroys that big, durability is poor to original structure
The problems such as;Built-in fitting occupied space is big, needs preservative treatment;Influence of the embedded bar then to construction formwork installation is big.Therefore, Shen
Asking someone, exploration exploitation is a kind of to occupy little space, not to influence the reinforcing bar company that construction formwork is installed, easy to operate, stress weight bearing power is strong
Binding structure.
