Swiss soil 马格巴 (Mageba) telescopic device bridge expansion joints for the past 20 years the usual form. As a well-designed telescopic device such alternative products, bridge expansion joints that strip section (bird-shaped rubber band) mode continuous beam joints, improvements in technology and development. Its reserved slot (Figure 5-21) and the corresponding series of technical design parameters and specifications listed in Table 5-9. Whether ribbon and box-section telescopic device d80 joints price, the same as the overall cross-sectional dimensions. They all have the same basic structure, and welded components are standard ST52-3 of manufacturing. A basic support system is the successful application of bridge expansion joints 20 years Mageba principle that each rigid steel beams welded to its corresponding joists (beams), this can be for all units and joists provide telescopic device supporting force transverse direction, bridge expansion joints and through elastic friction bearing preload force to prevent tilting. Preloading the same time to strengthen the torsion elastic contact point for all the support and each unit. Given the structural characteristics of this type of bridge expansion joints in the form of price sf80 joints, and then type in the Pavement complete with cutter cutting pavement, bridge expansion joints and injected construct caulking material made in its slot, the seams applies only to minor seams, the scope has been limited, bridge expansion joints, is a telescopic device in the form of independent chemical company by Xi'an style developed. Construction and principle. TST-type thermoplastic elastomer expansion devices, expansion joints and gravel-filled telescopic device, it applies to the amount of 50mm telescopic look occasions, mainly for road and bridge kerf, which consists of TST-type thermoplastic elastomer and gravel consisting of a telescopic device. Bridge expansion joints is a combination of polymer mixed with asphalt and fuel anti-aging agent multiple ingredients together. It is a specific type withstand transient mechanical loads and high frequency vibratory fully displayed flexibility. While under the influence of low-relief force is fully displayed plasticity, when the wheel driving obsolete bridge vibration-frequency vibration, TST thermoplastic elastomer show flexibility, stretching when the temperature changes, are low-relief force, bridge expansion joints complete display is plastic, and therefore, the level of stress is very small, so the adhesive surface but also to achieve easy detachment telescopic purpose. Bridge expansion joint design parameters. Continuous beam expansion joints, expansion joints, free installation guide provided by the manufacturer Hengshui HaoTong Rubber Company.
