With the rapid development of China's economy, with the highway represented sprung up highway, bridge expansion joints Highway Traffic increased dramatically mzl modulus joints, axle vehicles traveling on the road speed and vehicle growth People of driving comfort and other requirements are also increasing, so the previous issue of bridge design and construction related to inadequate attention joints devices, bridge expansion joints becomes a more prominent, forcing the bridge design, construction, maintenance and management give full attention to this sector. Bridge expansion joints affiliated with other components like bridges, with the need to bridge technological advances and applications, new emerging breed, all aspects of performance has been further improved. Rubber Co., Ltd. Hengshui Hao-design and production of various types of bridge expansion joint device too commercialized abroad, bridge expansion joints for many years after the actual project has been fully reflect their own characteristics and shortcomings, and summarize the past on the basis of experience, continuous improvement and perfection joints d60 price, product quality is also rising. Displacement of bridge expansion joints single stitch control system joints, elastic displacement control spring and its coordination in various movable beams and rubber sealing strip together to form a complete motion system (Figure 5-22). Control spring retractable path control of each unit within the gap, bridge expansion joints while elastic yield minus side of the decimal point its influence. Bridge expansion joint reaction force acting on the direction of displacement can be obtained by calculating the extreme. For the band-shaped sectional profile: compression 4KN / M, stretching 3KN / m; for the box-section type: compression 6KN / m, tensile 3KN / m. Nothing to do with the above limits the number of elements in the beam and stretching. mzl modulus joints joints _ _ Lianyungang please consult the price offered by Hengshui Hengshui Hao-Hao Tong Rubber Co. project. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
