Title:
DEFORMATION JOINT EXPANSION/CONTRACTION DEVICE, PAVEMENT STRUCTURE AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/077719
Kind Code:
A1
Abstract:
The present invention relates to the technical field of expansion/contraction devices, and in particular to a deformation joint expansion/contraction device, a pavement structure and a construction method therefor. The device is mounted in a recess above a deformation joint, and the device comprises: a displacement support plate, wherein the displacement support plate is arranged above the deformation joint, and the displacement support plate is fixedly arranged on one of two sides of the deformation joint; an elastic support assembly comprising fixed seats fixed to two sides of the displacement support plate and a rigid expansion/contraction member connected to the two fixed seats, the rigid expansion/contraction member being suspended and fixed above the deformation joint, and being elastic in the connection direction of the two fixed seats; and an elastomer with which the recess above the deformation joint is filled and which immerses the elastic support assembly, wherein two sides of the elastomer are connected to side walls of the recess above the deformation joint, and during expansion/contraction deformation of the deformation joint, the elastic support assembly provides deformation buffering force. According to the present invention, a steel member is introduced into an elastomer, so that the overall structural strength of the deformation expansion/contraction device is enhanced; and the integrity of pavement and the driving comfort are improved.
