Description

Pin rod method bent cap construction limit structure Technical Field The utility model belongs to the technical field of building construction, and particularly relates to a limit structure for capping beam construction by a pin method. Background In bridge engineering, capping beam construction is a key link for connecting pier columns and an upper structure, and the construction quality directly influences the overall stability and safety of a bridge. In traditional pin method bent cap construction, adopt fixed limit structure to fix a position the pin often, limit structure is many through welded fastening among the prior art, is difficult to adjust the pin position according to construction demand after the installation, leads to pier stud and girder's precision to be difficult to control. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a pin method bent cap construction limit structure which is used for solving the problems in the background art. In order to solve the technical problems, the utility model adopts the following technical scheme: The pin rod method bent cap construction limit structure is characterized by comprising a pier column, wherein the outer side of the pier column is connected with a fixed plate, a pin rod is connected to the inner side of the fixed plate in a sliding manner, the pin rod is connected with a limit device, an upper bearing plate and a lower bearing plate are arranged on the outer side of the pier column, the lower bearing plate is connected with the fixed plate, two double-spliced I-steel pieces are symmetrically arranged between the upper bearing plate and the lower bearing plate, and limit I-steel pieces are welded between the two double-spliced I-steel pieces. Preferably, two limiting I-beams are arranged and are in contact with two sides of the pier column. Preferably, the limiting device comprises a threaded rod, a limiting groove is formed in the inner side of the pin rod, the threaded rod is in threaded connection with the limiting groove, and the threaded rod penetrates through the fixed plate and is connected with a rotating block. Preferably, the upper end of the upper bearing plate is connected with a connecting plate, the connecting plate is connected with a protective net, and a shear support is arranged on the inner side of the protective net. Preferably, the two double-spliced I-beams are perpendicular to the limiting I-beam, and a plurality of reinforcing connection steels are arranged between the two double-spliced I-beams. Compared with the prior art, the utility model has the following beneficial effects: 1. The fixed plate in pier stud outside and sliding connection's round pin stick cooperation threaded rod limit structure, the horizontal adjustment of round pin stick position is realized to the rotatory turning block, guarantees that both sides round pin stick atress is even to improve the whole compressive strength of structure, limit groove and threaded rod's threaded connection design have strengthened spacing stability through the screw thread auto-lock characteristic, prevent the round pin stick skew in the work progress. 2.
