In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a construction reinforcing bar connects connection structure, includes reinforcing bar and joint, the pole body of reinforcing bar on be equipped with spiral rib just the reinforcing bar link processing have the threaded rod, the joint be steel tube-shape and medial surface processing have the internal thread, the joint outside welding have a mounting cylinder, the welding of mounting cylinder leading flank have the external section of thick bamboo that has the internal thread just the equal welded fastening of mounting cylinder trailing flank left and right sides have the connecting plate that has the mounting hole, the equal welded fastening of mounting cylinder both sides face have the telescopic link, the telescopic link expansion section on rotate and install the arc card frame that links two symmetries, the arc card frame of two symmetries block into the both sides spill regional position department of rib respectively, arc card frame below of two symmetries all be equipped with the screw thread through-hole just the screw rod is passed to the screw thread through-hole inside.

Further, the external cylinder is internally screwed into the rod-shaped supporting piece, and the connecting plate is connected with a concave clamping frame through a rotating shaft.

Further, the telescopic distance of the telescopic rod is fixed through a lock nut.

Further, the arc-shaped clamping frame is inclined at the same angle according to the inclination direction of the spiral rib.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, through a special mounting cylinder structure, the steel bar connecting structure is welded and fixed on the outer side of the joint, on one hand, the rib trend of the steel bar can be further limited, the shaking of the steel bars at two sides of a connecting position area is reduced, and meanwhile, the structure of limiting with an external component is designed, so that the stability of steel bar connection can be further improved.
