1. It is used for bridge expansion joints.

2. Good quality and competitive price.

 

The scope of application of the joint:

We produces a bridge expansion joints are produced by professional rubber-type devices, applied to the volume of ≤ *0mm telescopic following Road and Bridge: BF-type rubber plate in line with the telescopic device, it applies to the volume of ≤ **0mm telescopic following Road and Bridge does not apply to Highway; ZT-SF comb plate steel telescopic device is to be made across the telescopic comb-shaped space, the ride board at the other end of stainless steel, extendable up to *0mm more than the amount used for large and medium-sized long-span bridge; ZT-GQF-C-type (Z-type, F-type, M type, O type) and retractable telescopic device applicable to the volume of ≤ *0mm bridge; The ZT-GQF-MZL type telescopic device is connected by the special steel and machine components modulus of the bridge stretching device, it applies to the volume expansion of ******0mm in the bridge; ZT-XF series of telescopic device is parallel to the direction of the bridge joints shaped steel and angle and displacement of supporting me, and it also applies to in the volume expansion of ******0mm in bridge engineering.

 

Technical requirements:

1. Neoprene rubber used (ie, CR, applied to the temperature of **5 - **0 ) or the use of natural rubber (that is, NR, applied to the temperature of **0 - **0 region)

2. Telescopic device used in steel, the quality requirements in line with the GB**2, GB**4 provisions, the use of special steel, (that is, *6MN or Q**5) in line with the provisions of JT/T***1.

 

GQF-C-type bridge expansion devices

GQF-C-type bridge expansion device is adapted to the construction of roads and bridges in China a new type of bridge expansion joint devices. GQF-C-type bridge expansion device using the whole hot-rolled special steel *6Mn, overcome the special steel extrusion line and uneven collection of size characteristics, GQF-C-type bridge expansion joint integrated technical performance and technical indicators are at or better than similar products in the advanced level and special-shaped steel structure is an internal initiative rolling, traffic will become a recommended industry standard products.

 

GQF-C-type bridge expansion joint product features: Low building height, the overall shape of domestic hot-rolled special steel height *0mm, simple structure, easy installation, with significant reliability, comfort and durability. For Deck thickness equal to or greater than *0mm, less than or equal to *0mm telescopic amount of the various bridges, both for the convenience of the old bridge expansion joint replacement, but also for the selection of a new bridge built.

 

GQF-C-type bridge expansion joint rubber seal the middle of its technical requirements: The use of chloroprene rubber (CR) rubber seal with the application of the telescopic device and a temperature of **5 - **0 region. The use of natural rubber (NR) sealed with rubber installation of expansion joints for a temperature of **0 - **0 areas.
