Joints, 13833855982, cd80 bridge expansion joints supplied by the manufacturer Hengshui HaoTong Engineering Rubber Company. Joints, 13833855982, cd80 bridge expansion joints manufacturer Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) this year launched a new upgrade, the above picture is only for reference, please call the contact phone book pages or pictures on request The latest information, contact: Liu. Control Systems Control Systems bridge expansion joints displacement SG-type bridge expansion joint device is divided into two in parts: First, the anchor bolts provided cd80 sales on the side of the bridge expansion joints and beams supporting the bottom surface of the moving beam, both of which match the whole order control the maximum amount of displacement; the second is provided with a bolt retainer cd80 wholesale bridge expansion joints, bridge expansion joints on the split-beam webs when limited by the bolt gap stretched to the maximum, compressed to a minimum When controlled by touching the spring seat. In addition, the bridge expansion joints within the web in the spring seat set mandrel rod, together with specially designed springs to control the displacement equidistant between units (ie, the guarantee of uniformity of each slit stretching method - manufacturers Note) constructed As shown in Figure 5-10. Bridge expansion joints is entered after the 1990s the car to the world in the form of the most widely used engineering major telescopic device. Especially in the overall shaped steel forming technology after a major breakthrough, both in terms of quality as well as the supply of shaped steel beam steel has significant progress, wooden bridge expansion device is a comfort in the amount of stretching can adapt to any look The structure, bridge expansion joints and its main components can be standardized and serialized cd80 bridge expansion joints manufacturers to meet the needs of large bridge projects. Therefore, as previously described forms currently on the market, including domestic and foreign variety, there may be more and more, it differ from its technical performance point of view expansion joints, bridge expansion joints, but not very obvious, advantages and disadvantages, it can be said is not very well-structured, how to judge the relative good and bad of a structure, an important issue as the design, manufacture and applications can not be avoided, the normal use of the bridge project can not be ignored and editors immature views on the following aspects of the proposed.
