Description

Adjustable simple detection device for perpendicularity of bridge pier column

Technical Field

The utility model relates to a bridge straightness detection technology field that hangs down, in particular to bridge pier stud hangs down straightness simple and easy detection device with adjustable.

Background

The pier stud is used as an important component of the bridge, the appearance design and quality management of the pier stud have profound influence on the overall stability of the bridge, so that monitoring and measurement must be carried out on each construction stage, and in the monitoring and measurement process, according to the monitoring and measurement result, whether the deformation and stress change state of main components of each construction stage meet the design requirements or not is evaluated in time, and the safety of the construction process and whether the structure works normally or not are judged. The main tasks of construction monitoring are as follows: firstly, the geometric line shape required by design is ensured to be achieved after the structure is finished; secondly, the structure reaches a reasonable internal force state after being completed; and thirdly, the safety of the structure is ensured in the construction process. The bridge pier perpendicularity has certain influence on elevation control of a superstructure construction beam section, normal folding of a full bridge, bridge forming line shape, full bridge internal force distribution, construction safety, operation driving comfort degree after the bridge is built and the like. Therefore, the perpendicularity of the pier column must be monitored, and the project is guaranteed to meet the requirements of design and related construction technical specifications.

The perpendicularity of the bridge pier stud is directly influenced by the perpendicularity of the installation of the template, so that the perpendicularity of the template must be detected before concrete pouring, and the perpendicularity of the bridge pier stud is guaranteed. But because the outside of the template is uneven latticed surface or has reinforcing members such as battens, steel pipes, keels and the like, and the longitudinal section of the pier is mostly a special pier column such as a Y-shaped pier column, a rectangular pier column, a curved pier column and the like, the direct inspection by using the verticality guiding ruler is difficult. The current inspection method is to suspend a plumb line on one side of a template, measure the distance between the upper end and the lower end of the template and the plumb line by using a ruler, and judge whether the perpendicularity of the template meets the requirement by comparing two distance values. Obviously, the method is complicated and causes some human errors.

CN 108534648A discloses a perpendicularity measuring device for bridge construction, which includes a counterweight seat, a bottom plate and a lead weight, wherein a rotating support column is installed above the counterweight seat, the rotating support column is rotatably installed on the counterweight seat, a connecting column is arranged above the rotating support column, and the connecting column can ascend and descend along the axis of the rotating support column, and a locking nut is arranged on the connecting column, so as to lock and fix the connecting column, and the patent fixes the position of a cord at the top of the lead weight through a guide wheel, so as to improve the accuracy of measurement; drilling on the side wall of the pier is not needed, and only operation on the top surface of the pier is needed, so that the measuring safety can be greatly saved, and meanwhile, the measuring time can be saved.

Although the problem that the traditional measurement is inconvenient and the detection precision is poor is solved by the measuring device, the measuring device is inconvenient to observe a detection result, a plumb bob measuring mode is adopted, whether plumb bob lines deviate on the graduated scale or not needs to be observed after the plumb bob is static, in the actual measurement process, the swinging of the plumb bob needs a certain time to stop, the waste of detection time is caused, the detection efficiency is not high, the third device is heavy, the installation and the transportation are inconvenient, and the labor intensity of workers is high.
