Description

TECHNICAL FIELD

[0001] The utility model relates to bridge pier body reinforcement positioning technical field especially is related to a bridge pier body reinforcement positioning device. BACKGROUND

[0002] In the field of bridge construction engineering, bridge piers play a crucial role as the main supporting structure of bridges. They not only bear the weight of the superstructure but also must be able to withstand various external forces such as wind, water pressure, and seismic forces. Therefore, the stability and safety of the bridge pier directly affect the durability and safety of the entire bridge, making it a key link in bridge design and construction.

[0003] Bridge piers are usually composed of several important parts: the pile cap located underwater or below ground, which transmits the load of the bridge pier to the foundation; the main structure of the bridge pier, which bears and transmits the load from the superstructure; the beam cover connecting the bridge pier and the superstructure, which provides the necessary tensile strength for the pier body and enhances the mechanical properties of the concrete. The installation quality and positioning accuracy of the reinforcement have a decisive influence on the overall performance of the bridge pier. Reinforcement is not only an important component of concrete structures but also one of the key factors to ensure the good condition of the bridge pier during long-term service.

[0004] Traditional construction methods have obvious limitations in the installation process of pier body reinforcement. Due to the limitations of measurement tools and techniques, the positioning of pier body reinforcement often fails to achieve the desired accuracy. This may result in deviations between the actual installation position and design requirements, causing inconsistencies in the spacing between the reinforcement, even exceeding the error range allowed by relevant specifications. Such deviations can cause a series of problems: on the one hand, the internal stress distribution of the bridge pier becomes uneven, some areas may bear excessive stress, while other areas may not fully utilize their carrying capacity; on the other hand, the thickness of the concrete protective layer will also change, affecting the corrosion resistance of the reinforcement and the service life of the bridge. Over time, these problems may cause cracks or other structural damage to the bridge pier, threatening the safe operation of the entire bridge.
