Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, specifically to a multifunctional integrated positioning frame for pre-embedded reinforcement in pier body. Background Technology

[0002] Traditionally, the positioning frame for pre-embedded reinforcement bars in pier body is usually made of flat iron or channel steel with a toothed frame. During the pre-embedding construction of the reinforcement bars in pier body, the frame is fixed to the top of the pier cap formwork. When the pre-embedded reinforcement bars are installed, they are installed in close contact with the toothed edges of the frame, which can achieve the purpose of controlling the deviation of the pre-embedded reinforcement bars in pier body.

[0003] The drawback of the above technology is that it can only control the deviation of the embedded reinforcement bars in the pier body, but cannot control the elevation of the exposed part of the embedded reinforcement bars. For the construction of the pier body with the overall prefabrication and hoisting of the steel reinforcement cage, it is often difficult to connect the prefabricated cage with the embedded reinforcement bars due to the problem of varying lengths of the exposed reinforcement bars, which ultimately leads to the failure of the overall prefabrication and hoisting construction of the cage.

[0004] Therefore, we need to solve the problem of misalignment and elevation accuracy control of the pre-embedded reinforcement in the pier body. In this regard, this utility model provides a new technical solution. Utility Model Content
