And the board-like retractor device of comb.
Background technology
The retractor device that the board-like retractor device of comb deforms as a kind of bridge superstructure, because it is easy for installation, structure
The advantages such as simply, cost is low have obtained the extensive application of science of bridge building circle.The board-like retractor device of common comb is mainly by across seam
Fishback unit and fixed fingers Slab element composition, can be at suitable bridge to aspect generation telescopic displacement.But owing to heavy vehicle travels
During the effect of brake force, bigger to periphery concrete destruction across the power effect that is hit of seam fishback unit.Further, due to weight
Type vehicle travels reasons such as bringing to a halt to the board-like retractor device of comb, the volume of traffic is big, often occurs that connecting bolt destroys existing
As.In the course of time, the shortcomings such as the impact resistance of the board-like retractor device of common comb is weak, connecting bolt destructible can expose
Come so that it is occur in that certain limitation when application.
In the patent documentation of Application No. CN201420517470.0, disclose a kind of bridge with buffering energy-consumption function
The board-like retractor device of beam comb.This board-like retractor device of bridge comb is by across seam fishback unit, fixed fingers Slab element, elasticity
Displacement device, L-type connecting bolt and waterstop composition, the board-like retractor device of bridge comb is across being arranged between the beam of the left and right sides
In gap, fixed fingers Slab element is connected, across stitching fishback through cast-in-situ concrete beam face is fixing by L-type connecting bolt and right side beam
