Bridge expansion joints rubber seal bridge expansion joints by bird-shaped rubber band and clip block (or layering), with the upcoming rubber strip is pressed into the clamp block (or layering) of the groove, bridge expansion joints clamp block (or clip strip) at a certain distance from the outer edge of the longitudinal, steel bolt through the clamp blocks the rubber strip is clamped to the edge of the beam or beams under the intermediate flange, as shown in Figure 5-9 SSF-type bridge expansion joint device d40 steel expansion joints, the maximum displacement amount of 640mm. From 80 ~ 640mm, 80mm for the level to be divided, the amount is greater than 640mm telescopic individually designed according to needs. Reliable anchor, so far, recognize the important aspects of bridge expansion joints type of anchoring system, because if not handled properly anchoring system is prone to early damage, the best telescopic device will not normally use, so reliable The anchor should always be taken seriously enough in all aspects, plus good waterproof performance, this yong sealed rubber band stretching and defection as modulus telescopic device, bridge expansion joints than the ruler version telescopic device in a waterproof aspect well, as long as the well handled generally not easy to leak d80 steel expansion joints, and surface water can drain away from the bridge, however, from the current situation em80 shaped steel expansion joints, sealing rubber band with the opposite sex because of embedded solid steel not dense or treatment is not careful due to leakage problems. This will cause harm to the holder, bridge expansion joints especially strict requirements of the city's bridges, due to leakage adverse impact damage to the environment and so on. In other words, the problem loaded retractable waterproof device has become a heart disease has long bridge project, so should be taken seriously enough the design and production plants, must as soon as possible to solve this problem. Bridge expansion joints appear from the current view of the steel beams broken joints, in addition to a sense of ant-line production plant attention to provide qualified products, telescopic device manufacturing plant for use in steel beams must pay attention to starting testing work. If the material is somewhat problematic, in a vehicle under repeated heavy loads on the phenomenon of early fatigue damage may occur. d40 steel expansion joints | 13833855982 (certified) | joints by Hao Tong Engineering Rubber Co., Ltd.
