XF-type bridge expansion joint device bridge expansion joints are oblique-bearing bridge expansion joint device is determined by the Ministry of Railways Institute of Railway Construction, Hebei Hengshui City Rubber Co. and Shijiazhuang Traffic Survey and Design Institute jointly developed in 1993 in The Modular series. Bridge expansion joints and structural features principle: bridge expansion joints, mainly by the edge beam, the beam, the sealing rubber band, diagonal support beams, bearing pressure and compression, displacement control box and anchor steel components. Its edge beam and shaped steel beams using domestic extrusion. Its cross section is arranged as shown in Figure 5-12. F80 reliable anchor-type bridge expansion joints, so far, all aspects of bridge expansion joints anchoring system recognize important type bridge expansion joints manufacturers, because once handled properly anchoring system prone to early damage, the best telescopic device also can not normally use, so a reliable anchor should always be taken seriously enough in all aspects of bridge expansion joints, plus good waterproof performance, this yong sealed rubber band stretching and defection as modulus telescopic device, bridges joints than the ruler to the good version of the telescopic device in a waterproof, as long handled well generally not easy to leak, but water can drain away from the table on the deck, but d40 bridge expansion joints, from the current situation, since the seal steel embedded rubber band with the opposite sex is not dense or treatment is not solid and meticulous due to leakage problems. This will cause harm to the bearings, bridge expansion joints especially strict requirements of the city's bridges, due to leakage adverse effects such as damage to the environment. In other words, water problems mounted telescopic device has long become a heart disease bridge project, so should attract enough attention to design and manufacturing plant, must solve the problem as soon as possible in this regard. Bridge expansion joints in steel beams from the case at present appear broken view, in addition to a sense of ant line manufacturer attention to provide qualified products, telescopic device manufacturer for use in the steel beams from the flaw must pay attention to the work. If the material is somewhat problematic, repeated the role in the heavy vehicle loads on the phenomenon of early fatigue damage may occur. 160 bridge expansion joints bridge expansion joints _ _ Guangdong Hao-Hao Rubber pass by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
