Gqf-c40 pedestrian bridge girder expansion joint manufacture

  Gqf-c expansion joint has the characteristics of reliable connection, smooth connection with bridge chyme, sealing water, flexible expansion, stable driving and long service life
It is applicable to bridges with expansion capacity of 40mm, 60mm and 80mm
C
D-type and F-type bridge expansion joints are a novel bridge expansion device designed by the domestic transportation and highway planning and Design Institute
The products are suitable for highways, urban bridges, elevated roads and overpass projects in large traffic sections

Gqf-f40 / F60 / F80 bridge expansion joint, price of F-type bridge expansion joint, installation of F-type bridge expansion joint - manufacturer
Gqf-f bridge expansion joint is a novel bridge expansion device designed by CCCC highway planning and Design Institute
The product is suitable for highways, urban bridges, high price roads and overpass projects in large flow traffic areas

Main functions of bridge expansion joint: the bridge expansion joint is located at the movable end of the bridge superstructure and the broken joint of the bridge deck
It is mainly composed of force transfer support system and displacement control system
The main functions of the expansion joint of special-shaped steel bridge beam are: first, to transfer the vertical and horizontal loads of vehicles to the bridge beam body through the support structure; second, to adapt to the changes of longitudinal and transverse displacement of the bridge and the change of rotation angle caused by warping of the beam end
Model of bridge expansion device: the bridge expansion device can be divided into gqf-c type, gqf-z type, gqf-l type and gqf-f type according to the performance and installation method
Among them, gqf-mzl type bridge expansion joint device is a bridge expansion joint device designed by hot-rolled integrally formed special-shaped steel
Gqf-c, gqf-z, gqf-l and gqf-f expansion joint devices are suitable for bridge joints with expansion amount of less than 80mm
Gqf-mzl expansion joint device is a modular bridge expansion joint device composed of side beam, middle beam, cross beam and linkage mechanism, which is suitable for large and medium-span bridges with expansion amount of 80mm-1200mm

Due to the large joint distance, the shear force under the load and the inertia of the vehicle, the loose expansion joint rubber will be brought out of the positioning angle steel, resulting in another type of jumping
During construction, the anchor reinforcement of the expansion device is not welded firmly enough, or the phenomenon of missing embedded anchor reinforcement occurs, causing hidden dangers to the expansion joint itself;
