Type steel expansion joint

Type steel expansion joint in accordance with the performance and installation methods can be divided into: type GQF-MZL, type GQF-C, type GQF-Z, type GQF-L, type GQF-F.

Type GQF-C type, GQF-Z type, GQF-L type, GQF-F type telescopic slit apparatus is composed of two side beams (C type, Z type, F type, L type hot-rolled profiled steel) and rubber sealing belt. Applicable to the expansion of the amount of 0~80mm bridge bridge, classified according to the structure are as follows:
1. the pure rubber expansion device is composed of rubber (including special shaped steel beam height is not larger than 50mm and the sealing rubber belt). It is suitable for the bridge engineering of highway with no more than 60mm.
2. Plate expansion body made of rubber, steel or iron sulfide as one. It is used in expansion amount less than 60mm of road and bridge engineering, does not apply to highway and bridge engineering.
3. combined type telescopic unit telescopic body by the rubber plate and the steel plate combination. It applies to expansion amount is less than 12mm in road and bridge engineering, does not apply to highway and bridge engineering.
4. Modulus telescopic device is made of the overall shape of the special-shaped steel, by the edge of the beam, beam, beam, displacement control system, sealing rubber belt components. Modular bridge expansion device is divided into: type GQF-C bridge expansion device, GQF-MZL type of bridge telescoping device.

The characteristics: the whole body is good, high compressive and flexural strength, vehicle passed smoothly without jump, the noise is low.

Uses: various bends, the slope, the oblique, the wide bridge. The design of the Modular Expansion Joint displacement quantity can be designed according to the actual needs to be in accordance with a certain number of modules to fight.


Single slit from 8Omm to 12OOmm multiple joints, a total of 15, more than the amount of expansion, according to the design requirements of processing and manufacturing to meet the needs of users.

The type GQF-C bridge expansion device of building height 50mm. Only applicable to bridge deck pavement layer thickness is equal to or greater than 80mm, expansion amount less than or equal to 80mm various bridges, both for the convenience of old bridge expansion device replacement, and new bridges can select.

A.TCS plastic body can be directly tiled in bridge field joints, and form a continuum before and after the deck or pavement, the deck is flat seamless, driving more natural smooth, comfortable, no noise, small vibration than seamed bridge, and has advantages of convenient maintenance, cleaning and removing snow.
B. structure is simple, no need to set up a special expansion member, not in the beam end embedded anchorage reinforcement, construction is convenient and fast, after the pavement is cooling, you can open the traffic.
C. the elastic joints can absorb the deformation and vibration, and has the advantages of high damping, the damping bridge beneficial, can meet the vertical and horizontal vertical direction stretching and deformation of curved bridge, bridge slope, skew bridge, the bridge width.
D. because the joint and bridge deck pavement as a whole, so the sealing waterproof good, and resistance to acid and alkali corrosion.
E. replacement of the old bridge expansion joints can be half of the construction, the traffic do not interrupt traffic.
F. low cost, durable, less maintenance and replacement, economic and social benefits significantly.
