Prestressed concrete continuous beam bridge construction auxiliary device
The invention relates to a prestressed concrete continuous beam bridge construction auxiliary device, and relates to the technical field of bridge construction. Comprising a steel beam traction base, the two ends of the steel beam traction base are provided with supporting components capable of conducting inner supporting on a beam bridge duct, and the two ends of the steel beam traction base are further provided with fixing components capable of rapidly fixing a steel beam; the method can solve the following problems in the prior art: firstly, when a steel bundle is plugged into a pore channel of a concrete member, the end part of the steel bundle shakes along with pushing of the steel bundle into the pore channel, so that the end part of the steel bundle is in contact with the inner wall of the pore channel, and the inner wall of the pore channel is uneven, so that the end part of the steel bundle is clamped in the pore channel and cannot move; therefore, the steel beam perforating efficiency is influenced; and secondly, after the steel beam is perforated, tension needs to be applied to the steel beam so that the steel beam can be straightened in a hole channel of the concrete member, meanwhile, an anchorage device needs to be arranged at the end of the steel beam, the steel beam needs to be limited, and an existing anchorage device is poor in stability.
本发明涉及一种预应力混凝土连续梁桥施工辅助装置，且涉及桥梁施工的技术领域；包括钢束牵引底座，钢束牵引底座的两端设有能够对梁桥孔道进行内支撑的支撑部件，钢束牵引底座的两端还设置有能够对钢束进行快速固定的固定部件；本发明能够解决现有技术中存在的以下问题：首先，在将钢束塞至混凝土构件的孔道时，钢束的端部会随着钢束往孔道内部的推动而发生晃动，从而使其端部接触到孔道的内壁，而孔道内壁凹凸不平，会导致钢束的端部卡在孔道内无法移动，因此会影响钢束穿孔的效率；其次，钢束在穿孔后，需对钢束施加张力，使钢束在混凝土构件孔道内绷直，同时需要对钢束的端部设置锚具，对钢束进行限位，而现有锚具的稳定性较差。
