Description
TECHNICAL FIELD
[0001] The utility model belongs to annular concrete electric pole manufacturing technical field, concretely relates to a tool for electric pole reinforcing bar first head and then assembly. BACKGROUND
[0002] Concrete electric pole is generally assembled into large concrete electric pole through connecting flange for the convenience of transportation and the requirement of different erection height, and the reinforcing bar in the concrete electric pole needs to pass through the connecting flange, and then the subsequent process of pouring concrete is carried out, the centrifuge is used when pouring concrete, a plurality of through holes are formed in the end thereof, the reinforcing bar end passing through the connecting flange needs to be aligned with the through hole and then inserted into the through hole one by one before pouring, and the end of the reinforcing bar is headed to prevent the reinforcing bar from coming off in the centrifugal pouring process. This not only needs the worker to accurately align the hole position during installation, but also needs to spend a lot of time to align during actual operation, and the failure rate is high, and since the reinforcing bar is heavy, a plurality of persons need to operate simultaneously, which is time-consuming and laborious, affects the construction progress, and also affects the heading effect. SUMMARY
[0003] The utility model aims at overcoming the above-mentioned defects, providing a tool for electric pole reinforcing bar first head and then assembly, improving the efficiency of the heading process before building, and reducing the labor cost of workers.
[0004] The tool for electric pole reinforcing bar first head and then assembly is arranged in the electric pole centrifuge, and is characterized by comprising a groove plate, a tensioning plate, a screw rod and a limiting plate, wherein the diameters of the groove plate and the tensioning plate are matched with the inner diameter of the electric pole centrifuge, a plurality of reinforcing bar holes are uniformly formed in the groove plate in a ring shape, the groove plate is arranged on the front side of the tensioning plate, and the reinforcing bar passes through the groove plate through the reinforcing bar holes; a plurality of grooves are uniformly formed in the outer periphery of the tensioning plate in a ring shape, the number and position of the grooves are one-to-one corresponding to the reinforcing bar holes in the groove plate, the reinforcing bar is clamped into the bottom of the groove, a heading block is arranged at the end of the reinforcing bar, the width of the groove is smaller than the width of the heading block, one end of the screw rod is fixed to the center of the back of the tensioning plate, a screw hole matched with the diameter of the screw rod is formed in the center of the limiting plate, the limiting plate is arranged on the screw rod through the screw hole and is fixed by using a nut, and the diameter of the limiting plate is larger than the outer diameter of the electric pole centrifuge.
[0005] Further, sixteen reinforcing bar holes are formed in the groove plate, and sixteen grooves are arranged on the tensioning plate.
[0006] The utility model has the advantages that the reinforcing bar is directly headed after passing through the groove plate, and then the reinforcing bar is clamped into the groove of the tensioning plate, so that the operation of first heading and then assembly is realized, the hole position needs not to be accurately aligned, the operation difficulty is reduced, the operation time is reduced, the operation difficulty of the worker is reduced, and the construction efficiency is improved.
