Model of
Bridge Expansion JointMy company is the production of bridge expansion joint model is complete, mainly: gqf-c, GQF-Z, GQF-L, GQF-F, sewing mode number bridge expansion or contraction of the GQF-MZL. It is using hot rolled the overall shape of the special-shaped steel design of bridge expansion joint device. GQF-L which type gqf-c, GQF-Z type, GQF-F telescopic joint for expansion amount less than 80mm of bridge joint.
By the edge of the beam, beam, beam and the interlock mechanism is composed of modular bridge expansion device is GQF-MZL for 80mm-1200mm expansion amount large and medium-sized span bridge.
Plate expansion joints: made of rubber, steel or iron sulfide is one of the retractable device for expansion amount is less than or equal to 6Omm ordinary highway bridge.
Combined type joints: by a combination of rubber plate and steel plate and bridge engineering, suitable for ordinary highway expansion is less than 12Omm.
Manufacturing requirements according to the 12OOmm 8Omm from an arbitrary set of modulus type expansion joints: the overall molding special-shaped steel made by the edge of the beam, the beam, the beam, the displacement control system, sealing rubber belt components. Its characteristic is the overall good flexural compressive strength is high, after the vehicle is stationary without jump, noise low. Suitable for different bending, slope, oblique, wide bridge.
Modular Expansion Joint displacement is designed according to the actual need to follow certain modules together. The single seam to seam, is divided into 15, the expansion rate is higher than 12OOmm, design and processing, to meet the needs of users. The expansion joints used in highway bridge engineering.
Range of rubber used in bridge expansion device:1, the use of rubber (CR) expansion joint device for the temperature of +60 - -25 area;2,The use of natural rubber (NR) device is suitable for temperature -40+60 seam area expansion.
Expansion joint stretch shrinkage determined for expansion amount calculated directly influence of expansion joint specifications selection, if the expansion amount of choice is not reasonable, a direct impact on the extension and the use effect of the product, and selection of highway bridge expansion joint should also consider beam, plate telescopic device gap size, to ensure that the expansion joint device and beam, plate at both ends have sufficient anchorage, in order to achieve the best results. So in the selection of expansion joint of specifications, be sure to leave enough margin, in order to ensure the expansion joints, the use effect and durability.
QF-C type bridge expansion joint product features: low building height, homemade hot rolled integral molding special-shaped steel height only 50mm, simple structure, convenient installation, with significant reliability, comfort and resistance for a long time. Applicable to bridge deck pavement layer thickness is equal to Or more than 80mm, the amount of contraction is less than or equal to 80mm of a variety of bridges, both to facilitate the replacement of old bridge expansion joints, but also for the construction of new bridges selection.
