Beijing-joints quality and quantity highway bridge expansion joints rubber factory is a gem of wisdom

Beijing-joints quality and quantity highway bridge expansion joints rubber manufacturers wisdom gem 18230181118 joints according to performance and installation methods can be divided into: GQF-C type, GQF-Z type, GQF-L type, GQF-F type. Which GQF-MZL number of model type bridge expansion joint device is the use of hot-rolled steel bridge expansion joint device shaped the overall shape of the design. GQF-C type, GQF-Z type, GQF-L type, GQF-F-type expansion joint device for stretching the amount of 80mm below the bridge joints, GQF-MZL-type expansion joint device is by the side beams, beams, beam Modular bridge expansion joint devices and interlocking institutions, and for stretching the amount of 80mm-1200mm of large and medium span bridges. Road bridge expansion into: Modular bridge expansion devices and KS telescopic device and TST thermoplastic elastomer telescopic device Modular Modular bridge expansion into: GQF-C-type bridge expansion devices, GQF-MZL-type bridge expansion means CQF bridge expansion joints 1, GQF-C-type bridge expansion features: GQF-C-type bridge expansion with the overall hot-rolled special steel 16Mn overcome the squeeze profiled steel straightness and collection of non-uniform size characteristics, low building height domestic hot-rolled overall shape shaped steel height of only 50mm, simple structure, easy installation, with significant reliability, comfort and durability. Replacing old telescopic device is convenient, but when the choice for Newbridge. Selection principles: deck pavement layer thickness ≥80mm amount of stretching ≤80mm 2, GQF-MZL-type bridge expansion features: MZL telescopic device structure prominent features are: by the side beams, beams, beam, displacement control system, seal Series telescopic device consisting of a rubber belt member. Load-bearing structure and the displacement control system of the telescopic device is separated from the force when the two non-interfering, clear division of labor, so that not only guarantee the security forces, while maintaining a uniform displacement, so that all the beams are supported by a displacement control box a vertical beam in the same traditional practices, so that the large amount of displacement of the telescopic device is very advantageous to reduce the number of beams, so that the displacement of the control box volume is reduced to a minimum, saving the steel. The structure also overcomes the oblique supporting telescopic devices require very high precision machining and assembly of the harsh conditions, or a four-link structure prone to self-locking phenomenon, affecting extendable and easy to ensure uniform displacement ills. The structure of each connection are used both to rotate and can slide structure. Therefore, the curved, sloping, oblique, wide bridge adaptable to meet various requirements of the bridge structure. Leaping Leaping joints KS series is the latest development of a new type of expansion joint products, it only deck pavement layer thickness can achieve a reliable anchorage of the bridge design and construction units to provide a great convenience. At the same time it is good water resistance, shock absorption, reasonable force, to the end of the beam gap is not sensitive to construction errors, long service life, automatically clean up garbage in the seam, less maintenance, and low cost. So the product available that have been widely praised in bridge design and construction units. The company specializes in the production of two-component polysulfide sealant, rubber water stop, rubber seal, water swelling rubber seal, closed-cell polyethylene foam, inflatable mandrel, rubber bearings, expansion joints, two-component polyurethane sealants.
