Bridge expansion joints main design parameters: bridge expansion joints, according to the different forms of support beams are arranged divided into A, B and C three kinds. Their relevant design parameters such as type A is listed as shown in Figure 5-15 and Table 5-5. The method is more difficult joints bridge expansion joints, vary according to the size of each form of good roads and bridges flux structure, but generally repair or replacement, especially the highway, traffic volume and bridge construction When the need to implement a form different from repair of traffic control, bridge expansion joints joints d480 practice shows that even in the design and construction are sure reasonable and perfect telescopic device, comb plate joints after completion of the project, once open traffic. Examples of bridge expansion joints that defects in children with early damage, there are many, therefore, bridges telescopic devices, the design and construction can not have a little flawed. To this end, the reasons for defects and damage in the past telescopic devices were carefully constructed summary branch type bridge expansion joints and necessary. As the circle of our highways and city roads joints e40, compete for traffic and heavy vehicles, the initial and middle stages and so on. Most of the state has been showing damage. Modular expansion joints, expansion joints Shanghai, manufacturers have stock HaoTong provided by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co.
