Bridge expansion joints bridge expansion joints rubber seals from bird-shaped rubber band and clip block (or layering), with the upcoming rubber strip is pressed into the clamp block (or layering) of the groove, bridge expansion joints clamp block (or clip strip) outer edge of the vertical intervals from gqf80 type expansion joints, steel bolts through the rubber bands clamping block clamped to the side under the intermediate beam or beam flange, Figure SSF-type bridge expansion joint device, the maximum displacement in Figure 5-9 amount of 640mm. Shaped joints from 80 ~ 640mm to 80mm for the primary division, greater than 640mm amount of stretching can be individually designed according to the needs. 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, 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, the same as the overall cross-sectional dimensions. They all have the same basic structure gqf60 type joints, and welded components are standard ST52-3 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. gqf60 type expansion joints, expansion joints Siping, 13,833,855,982 provided by Hengshui Hao Tong Rubber Co. project.
