 Bridge expansion joints 1, GQF-C-type bridge expansion Features: GQF-C-type bridge expansion with the overall hot-rolled special steel 16Mn overcome extrusion profiled steel straightness and collection size uneven features, low building height, domestic the overall shape of hot-rolled shaped steel height of only 50mm, simple structure, easy installation, with significant reliability, comfort and durability. Telescopic device is convenient to replace the old, and the choice is available when the new bridge. Selection principles: deck pavement layer thickness 80mm telescopic amount 80mm 2, GQF-MZL-type bridge expansion Features: MZL-type bridge expansion joint device structure prominent features are: by the side beams, beams, beam, displacement control system, sealed Series telescopic device consisting of a rubber band and other components. Load-bearing structures and displacement control system of the telescopic device separately without disturbing each other when the two forces, a 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 displacement of the telescopic device is very beneficial, reducing 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, otherwise the four-link structure prone to self-locking phenomenon, affecting free and easy expansion displacement guarantee uniform * disease. The structure of each connection are used both to rotate and can slide structure. Therefore, the curved, sloping, oblique, wide bridge adaptable to meet the requirements of various bridge structures. Bridge expansion joints docking docking bridge expansion joint device, depending on its structure and mechanical characteristics of the form can be divided into packing and embedded solid butt butt type two. Padded butt type telescopic device is asphalt, wood, oakum, rubber and other materials filling the gap, stretching the body in any case are in compression. Such telescopic device is generally used in the amount of stretching conventional 40mm below the bridge project, it has been rare. Embedded solid docking expansion joint device using different forms of steel members will be different shapes rubber strip (band) embedded firmly fixed, and the rubber strip (with) the tensile and compressive deformation to absorb deformation of the beam, which can be in the body by stretching pressure state. Also in tension. Modulus-bearing bridge expansion joints when stretching deformation of the bridge over 50mm, often with steel telescopic device. The telescopic device when the vehicle is often due to the end of the beam passing through the rotation or deflection produced slap effect, noise, and easy to make structural damage. Therefore, the device has a bolt requires the use of a spring to fix the slide plate to reduce the rattling and noise, the joints of the structure is relatively complex. Bridge expansion joints shear the device is the use of a variety of different cross-sectional shape of the rubber band as a caulking material telescopic device. The rubber elastic, easy to paste, but also to meet the requirements and have waterproof deformation. In domestic and foreign bridge engineering has been widely used. Bridge expansion joints Steel Plate rubber bearing telescopic device of this type, it is difficult to meet the requirements of a large amount of displacement; steel type of telescopic device, it is difficult to achieve watertight seal, and easy to impact on the vehicle, affect vehicle The driving performance. Therefore, there has been a good performance and easy to use shock-absorbing cushion rubber sealing material to do with the strength of good performance shaped steel combination, in the case of a large amount of displacement of the vehicle can withstand the load-supporting several types of mold (Modular ) bridge expansion series. Bridge expansion joints elastomer elastomer telescopic device into zinc metal joints and TST gravel elastic joints, elastomer telescopic device is a simple expansion joint device for small and medium-span bridges, when the amount of stretching in the 20mm-40mm TST can be used within the gravel when the elastic expansion joint device, specially after the TST elastic-plastic material is heated and melted, poured into the gravel after cleaning heating, that the formation of elastic joints TST gravel, gravel to support vehicle load, TST elastic-plastic body at a 25 to 60 conditions to meet the requirements of the amount of stretch. Type expansion joints in accordance with the 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 shaped steel bridge expansion joint device 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. Bridge expansion joints refers to the deformation of the bridge to meet the requirements, usually between two end of the beam, or set the position articulated joints on the bridge between the end of the beam and the abutment. Require expansion joints in parallel, perpendicular to the axis of the bridge in both directions, can freely scalable, secure and reliable vehicle should be smooth too, no sudden jump and noise; to be able to prevent the infiltration of rainwater and garbage soil obstruction; installation, inspection, maintenance eliminate the dirt to be simple and easy to use. Set expansion joints, railings and the bridge deck to be disconnected. Hebei Zaojiang Dong Xin bridge parts factory, specializing in the production of bridge expansion joints, since its inception, with excellent quality and full service and win new customers. Note: The selection of C-type steel expansion joint, F-type 180 yuan / m (specific customized according to drawings, price negotiation).
