Multifunctional basin-type support and a method for installing and measuring force and adjusting height

Abstract

A multifunctional basin-type support comprises a support body, a height adjusting system and a force measuring system; the height adjusting system comprises an adjusting seal plate, a filling gasket plate and an external high-pressure filling device, wherein a sealed space is formed between the adjusting seal plate and the filling gasket plate, a filling pipe on the filling gasket plate leads to the sealed space, an inlet of the filling pipe is communicated with a height adjusting pipe interface on the outside of the base plate of the support, and a high-pressure filling device. The force measuring system comprises a pressure-bearing elastomer enclosed at the bottom of the filling pad and a fiber Bragg grating force measuring element in contact with the pressure-bearing elastomer. The outer end of the fiber Bragg grating force measuring element is connected with a detecting device by a signal line. A method for installing and measuring force and adjusting height comprises a mounting support, a measuring force, adjusting height, removing high-pressure filling device and monitoring. The multi-functional basin-type support is provided with a height adjustment system and a force measuring system, and can realize stepless height adjustment by filling the filling material. The construction is convenient, and the height adjustment method is simple and reliable. The vertical bearing capacity of the bearing can be monitored accurately, continuously and effectively by the force measuring system.

Description

technical field [0001] The invention relates to a bridge structural part and a method for measuring force and height adjustment, in particular to a multifunctional basin-type support and a method for installing and performing force measurement and height adjustment. Background technique [0002] The bridge bearing is an important structural component connecting the upper structure and the lower structure of the bridge. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the upper structure of the bridge to the lower structure of the bridge. Among them, the basin bearing has a large bearing capacity, It has the advantages of large displacement, flexible rotation angle, consistent rotation performance in all directions, and wide application range of temperature, so it is widely used in municipal, highway, and railway bridges. [0003] During the construction and operation of the bridge, in order to ensure the safety of the bridge, f...

Problems solved by technology

[0010] (1) The height adjustment of the backing plate and the spiral height adjustment method need to lift the beam body to realize the height adjustment of the support. The height adjustment method and process are complicated, the construction is troublesome, and the cost is high;

[0011] (2) Although the method of filling and height adjustment does not require jacking up the beam body, before the height adjustment, it can only be determined according to the theoretical bearing force of the support or through manual detection of the force of the support to determine the height adjustment amount and determine the height adjustment. The high-volume period is long and the accuracy rate is low. It is impossible to determine the force change of each support during and after the height adjustment process, which brings hidden dangers to the safety of the structure.
