Comb tooth type damping displacement bridge expansion device

Abstract

The invention provides a comb tooth type damping displacement bridge expansion device, relates to the technical field of bridge building facilities, and solves the problem that bridge floor deformation hidden danger cannot be detected at present, the comb tooth type damping displacement bridge expansion device comprises a comb tooth main plate and a comb tooth auxiliary plate, a clamping groove is formed in the edge side of the top end of the comb tooth main plate, and an indication column is slidably connected into the clamping groove; the indication column comprises a reflective spherical mirror, a first signal identifier and a second signal identifier, the bottom end of the indication column is connected with a dip angle block, the joint of the indication column and the dip angle block is sleeved with a limiting plate, and the side, close to the outer wall of the limiting plate, of the indication column is sleeved with a second compression spring; the adjacent sides of the main comb tooth plate and the auxiliary comb tooth plate are respectively connected with a plurality of comb tooth bodies, each comb tooth body comprises main comb teeth and auxiliary comb teeth, and the main comb teeth and the auxiliary comb teeth are distributed in a staggered mode. According to the invention, the deformation condition of the bridge floor can be effectively detected, and passing vehicles are reminded, so that the effect of safety prevention is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction facilities, and more specifically relates to a comb-tooth type vibration-absorbing displacement bridge telescopic device. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly, and bridge expansion devices are generally installed during the construction process or later maintenance and transformation of bridges to improve the safety of bridge structures Among them, the bridge expansion device means that in order to meet the deformation requirements of the bridge deck, the expansion device is usually installed between the ends of the two beams, between the end of the beam and the abutment, or at the hinge position of the bridge. The expansion device of the bridge is an important part of the bridge. [0003] Based on the above, the inventors have found that there is the following problem: t...
