Expansion joints can be categorized according to performance and installation methods:GQF-C Type, GQF-Z Type, GQF-L Type, GQF-F Type.

Amongst themThe GQF-MZL type modular bridge expansion joint device is a bridge expansion joint designed with extruded steel sections. The GQF-C, GQF-Z, GQF-L, and GQF-F expansion joint devices are suitable for bridge joints with expansion of less than 80mm. The GQF-MZL expansion joint device, composed of side beams, middle beams, cross beams, and a linkage mechanism, is a modular bridge expansion joint suitable for medium to large span bridges with expansion of 80mm to 1200mm.

Highway bridge expansion joints are divided into: modular bridge expansion joints andKS Telescopic Device and TST Elastomeric Telescopic Device

Modular bridge expansion joints are categorized as:GQF-C Type Bridge Expansion Device, GQF-MZL Type Bridge Expansion Device

CQF Bridge Expansion Joints

1. Features of GQF-C Type Bridge Expansion Device:

The GQF-C type bridge expansion joint utilizes solid hot-rolled 16Mn special-shaped steel, overcoming the characteristics of uneven straightness and assembly dimensions in extruded special-shaped steel. It features a low construction height, with the height of the domestically produced solid hot-rolled special-shaped steel only 50mm, a simple structure, easy installation, and exhibits clear reliability, comfort, and durability. It is convenient for replacing old expansion joints and can also be selected for new bridges.

Selection Principle:

Bridge deck paving thickness≥80mm

Tensile Range≤80mm
