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 the use of chain-link mechanism connecting joints, bridge expansion joints with good uniformity c60 joints, and won in 1999 the Ministry of Communications Science and Technology Progress Award, detailed relevant GQF-MZL type telescopic device See description 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 gqff80 joints, the corresponding design parameters and specifications Series Table. Drink pressed bearing bridge expansion joints to absorb deformation overturning steel beams, so the relatively worse. Bridge expansion joints in this area are basically domestic product does not do what the experimental study, almost no consideration in this regard is a major flaw, bridge expansion joints in Germany, the latest product standards telescopic device, clearly shows the use of the bridge, Therefore d80 joints, the country also should make efforts towards this aspect. Bridge expansion joints on the current market supply of products from the practical application of engineering point of view, much more decent quality products, but most of them copy, repeat there is no feature of the original problem still exists which is a Reality, of course, bridge expansion joints hope more good new products on the market, but for existing products to improve and perfect if style is probably the main bridge expansion joints because the existing products have more engineering practice tests, what problems have exposed the need to improve and perfect the place is also very clear on the bridge expansion joints reality Korea still six original level set, or even the market in order to fight the phenomenon of shoddy, it is obvious . c60 joints | Chongqing joints | 13833855982 Tong Hao provided by Hengshui Rubber Company.
