TECHNICAL FIELD
[0001] The utility model relates to bridge building technical field, especially, relate to steel structure bridge whole life cycle measuring point device. BACKGROUND
[0002] Steel structure bridge as an important traffic infrastructure, plays a key role in modern city construction and transportation. In order to ensure the safety and durability of steel structure bridge, monitoring and maintenance in whole life cycle are crucial. In traditional bridge monitoring, prism is often used as an auxiliary monitoring tool. The main function of prism is to serve as a reflection target for optical measuring instruments (such as total station or theodolite). Total station or theodolite emits laser or infrared light beam to prism, and prism reflects light back to the instrument, and the instrument calculates the position, distance and angle of the target point by measuring the round trip time or angle change of the light beam. By installing prism at the key parts of the building structure and regularly measuring with total station, the deformation of the structure such as displacement, settlement and inclination can be monitored. However, when the traditional prism is fixedly installed on the steel structure bridge, the two ends of the steel structure pole where the prism is usually installed are connected with other structures, so that during installation, the prism cannot be simply sleeved on the steel structure pole. Usually, a hole position needs to be processed on the steel structure pole to install the prism, which leads to more troublesome installation and may also affect the strength of the steel structure pole itself.

[0037] The side connecting piece 300 is symmetrically provided with two, and each side connecting piece 300 corresponds to a group of limiting holes 211, the side connecting piece 300 comprises a supporting plate 310 and a top plate 320, the supporting plate 310 is provided with a limiting column 311, and the limiting column 311 is embedded in the corresponding group of limiting holes 211; the upper surface of the supporting plate 310 is attached to the base plate 210, the top plate 320 is fixedly connected with the supporting plate 310 and located above the steel structure pole 100, and the top plate 320 is provided with a first threaded hole 321.
[0038] Set screws 400 are symmetrically arranged on the left and right sides. Set screws 400 are threaded into the first threaded hole 321. The bottom of set screws 400 abuts against the upper surface of steel structure rod 100.
[0039] The prism assembly 500 is fixedly mounted on the mounting boss 220.
[0040] The steel structure bridge full-life-cycle measuring device provided by this utility model achieves stable installation of the measuring device through the combination of the steel structure rod 100 and the mounting base 200. The limiting hole 211 on the base plate 210 and the limiting post 311 on the side connector 300 cooperate to ensure the precise alignment and stable connection between the side connector 300 and the mounting base 200. This eliminates the need for fasteners when connecting the side connector 300 and the mounting base 200. Through the action of the set screw 400, the base plate 210 and the steel structure rod 100 are clamped and fixed by the support plate 310, and the support plate 310 is also fixed in position because the limiting post 311 is embedded in the limiting hole 211.
