Description
Technical Field

[0002] A continuous rigid frame bridge is a continuous beam bridge with the pier and beam consolidated. It is one of the main bridge types of prestressed concrete long-span beam bridges. It combines the stress characteristics of continuous beams and T-shaped rigid frame bridges. The multi-span main girders are made into a continuous beam body and consolidated with thin-walled piers. When erecting a continuous rigid frame bridge, in order to improve the overall use safety, it is necessary to carry out temporary constraints on it, and thus a constraint device is needed. The existing temporary constraint devices have a simple structure, so the constraint effect on the rigid frame bridge is not significant enough, affecting the construction safety. Based on this, it is necessary to provide a constraint device that can significantly improve the constraint strength and construction safety. In addition, the existing constraint devices are fixed structures and are not convenient for constraining rigid frame bridges of different lengths, thus affecting the versatility. Based on this, it is necessary to provide a constraint device that can constrain rigid frame bridges of different lengths and enhance the versatility. Content of the Utility Model

At this time, the restraint steels 101 can limit the rigid frame bridge bodies 300 at this installation position, and the two restraint plates 108 can clamp the rigid frame bridge bodies 300 from the upper and lower ends. At the same time, several anti-slip ribs 140 with a positive conical structure on the opposite surfaces of the two restraint plates 108 in the connection groove 107 can enhance the friction with the rigid frame bridge bodies 300, thereby significantly improving the restraint stability.
