Abstract

The invention relates to a basalt fiber comb plate and a telescopic member and a telescopic device using the comb plate. The comb plate includes a comb plate body, and the front end of the comb plate body is provided with a guide structure for moving along the left and right directions and cooperating with the front guide rail. The rear end of the comb body is used to extend into the front comb telescopic section between the corresponding two adjacent rear combs. The top of the front comb telescopic section is provided with a front comb step groove, and the front top of the comb body faces There is a front comb gap retaining edge for blocking the upper side of the corresponding rear comb step groove left or rightward. The invention solves the technical problem in the prior art that the rear side of the front comb plate and the front side of the rear comb plate are prone to fall from impurities and cause blockage.

Description

technical field [0001] The invention relates to a basalt fiber comb board in the field of bridge construction, a telescopic member and a telescopic device using the comb board. Background technique [0002] In the process of road construction, bridges are the main means of crossing obstacles such as rivers, deep valleys, and roads. Due to thermal expansion and contraction caused by temperature changes, the bridge deck will produce longitudinal expansion and contraction deformation. Freely deformable telescopic devices are installed between the platforms to ensure the smoothness of the bridge deck and protect the structure. [0003] Existing telescopic devices such as "a kind of comb-type telescopic device and telescopic member" disclosed in Chinese patent CN110241719A, the comb-type telescopic device, that is, the comb-type telescopic device includes a front telescopic member and a rear telescopic member, and the front telescopic member includes a length along the The front...
