Bridge expansion joints bridge expansion joints, is a 1993 combined with our transportation industry standards "highway bridge rubber expansion device" developed modulus telescopic device products. The product has completed expansion volume 80 ~ 2000mm range series design, bridge expansion joints for the use of various types of new bridges, but also for the telescopic device to replace the old bridge into the selection. The product is even chain-link mechanism, bridge expansion joints with good stretch uniformity, and won in 1999 the Ministry of Communications Science and Technology Progress Award em80 joints, detailed relevant GQF-MZL type telescopic device description, see Hengshui Hao-product manual. Its reserve tank and locate the typical cross-section of the joist set aside 5-6 slots as shown in Figure 5-16 and Figure 5-17 gqfc60 joints, the corresponding design parameters and specifications Series Table. Many necrosis telescopic device described above are only adapt to the longitudinal and vertical deformation of bridge structures, bridge expansion deformation in three dimensions can be adapted to vertical and horizontal, vertical deformation, bridge expansion joint device can be adapted to the three-dimensional deformation direction vertical, horizontal and vertical deformation in three directions need, at present, due to the rapid transport of the circle, the bridge structure in the form of constantly updated, increased urban interchanges, bridge expansion joints suitable for three-dimensional deformation of bridge structure opposite direction of deformation required bridge expansion becomes very important cd60 joints, Japan SG-dimensional telescopic device, common in Japan SG-30-SG-110 telescopic device which direction deformation function has three joints, which means the overall use of rubber made according to the use of the unique combination of a rubber material, which does not require screws or adhesive fixing, lateral deformation when it is not structural member between the upper and lower dislocation, bridge expansion joints to keep the vehicle's stability, not moving generate noise, which has a good durability and wear waterproof. Our three-dimensional bridge expansion telescopic device in addition a three-dimensional direction of deformation, deformation telescopic device is one of the three directions of the earlier used. According to the maximum width of the vertical GQF-MZL480 type bridge expansion joints is 480mm, and the formation of 5% longitudinal slope when dislocation simulation test, up to 24mm in height on both sides of the case, although telescopic friction resistance state more than the normal position about 15%, and the greater height increase frictional resistance, the more tendency, but still normal 5% longitudinal stretch. That bridge expansion joints and beams at times ridgepole state by force, by varying the pressure bearing and bearing deposit amount under the beam rotation and deformation of the support shaft, sliding bearing rotation adjustment, fully able to adapt to a certain amount The lateral deformation requirements, and to ensure uniform displacement, small friction resistance characteristics. cd60 joints | Jilin joints | 13833855982 Tong Hao provided by Hengshui Rubber Company.
