Pot type rubber bearing for measuring force and adjusting height

Abstract

The invention belongs to the technical field of bridge bearings and particularly discloses a pot type rubber bearing for measuring force and adjusting height.The bearing structurally comprises a lower bearing plate provided with a pot cavity, a seismic mitigation and absorption structure composed of an upper bearing plate, a spherical crown plate and a middle steel linear plate is arranged in the pot cavity of the lower bearing plate, and the lower bearing plate is provided with adjusting holes which are communicated with the pot cavity and provided with blocking wires; sealing rings are arranged on the middle steel linear plate and the side wall of the pot cavity to form a confined space in the pot cavity; a pressure-bearing rubber cushion layer is arranged on the bottom face of the middle steel linear plate, and solid matter with a low melting point such as paraffin is arranged in a space formed by the pot cavity of the lower bearing plate and the rubber cushion layer; at least one barrel-shaped groove is formed in the side wall of the pot cavity, and pressure sensing mechanisms fixed in the barrel-shaped grooves are connected with induction signal lines capable of being connected with an external detection mechanism.Through the pot type rubber bearing for measuring force and adjusting height, change in the turn angle of a bridge due to the action of geological conditions or other stress can be realized, the height adjusting function can be achieved, and the stress of the bridge can be detected in real time.

Description

technical field [0001] The invention belongs to the technical field of bridge bearings, and relates to a force-measuring height-adjusting pot-type rubber bearing that can detect its bearing capacity in real time. Background technique [0002] As the span of the bridge structure becomes larger and larger, the structural types become more and more complex and diverse. The common feature of these long-span complex bridge structures is that they all belong to high-order statically indeterminate structures, and the calculation of their internal forces is very complicated. Due to the influence of various factors such as the error caused by the simplification of the calculation model, the difference in the mechanical properties of the material, the construction error, and the uneven temperature change of each part of the structure, the internal force of the structure during construction or after completion differs greatly from the design value. Moreover, these differences are diff...

Problems solved by technology

At present, most of the products that use the support for force measurement place the force measuring equipment in the vertical position of the support, so it will be very inconvenient to replace, and the service life of the electronic equipment is relatively short compared with the support and bridge, so it needs to be replaced in time Otherwise, it will cause long-term use failure, and it is difficult to realize the monitoring and adjustment of the support
