Germany Maurer (Maurer) telescopic device bridge expansion joints, its force in the beam edge beam and hierarchical (above) after rolling profiled steel welded. Early use of steel box beams, structural steel beams and corrugated box side rubber composition (Figure 5-18), and provides 60mm and 80mm as a unit modulo two series (Table 5-7). More recent bridge expansion joints using Z-shaped side sill beams and king with a bird-shaped rubber band combined structure (Figure 5-19) to 80mm as a unit modulus series of specifications listed in Table 5-8. Bridge expansion joints displacement control system, in addition to have been made by the use of beam oblique angle changes to a scalable solution, while the use of elastic displacement control system mainly mechanism (Figure 5-20) for bridge expansion joints are constructed from cardboard chute, rubber body, anchoring system 4 large parts, such a telescopic device that was used to connect parts of Nanchang, Jiangxi Province of Interchange and the main bridge expansion joints d-160, in good condition, its layout, the working principle of the device Y physiognomy is alternately chanting upper and lower plate fixed to the end, the other end of the seat in a special chute along the bridge to the grassy vertical sliding em80 type expansion joints, there are alternate fiber material, bridge expansion joints it has a certain stiffness. There are stainless steel chute adhesive PTFE plate composed of its friction coefficient is small, easy to slide, the beam ends of the Y intersection chant body pressed into the chute, the inherent good sealing performance, good waterproof effect, anchoring systems reliable. British Horner three telescopic device, its structure is essentially a kind of welded joints or rolling road construction, bridge expansion joints or heterosexual steel continuous sealing tape and extruded anchoring system combination, according to different anchor form, which echoes the technical indicators. New Jersey-style telescopic device is a telescopic device in the form of a guardrail, it can be said is an adaptation telescopic device 3 direction deformation. Bridge expansion joints in addition to the normal longitudinal test, and pending the lateral dislocation simulations 35mm and 44mm, the horizontal resistance increase when measured in telescopic small displacement measurement uniformity single slit width 2mm difference compared with the standard value In this case the level of dislocation in the beam deviation is very small, almost equal, bridge expansion joints Description GQF-MZL type telescopic device lateral dislocation has a strong adaptability That GQF-MZL telescopic device components and sealing it with a normal rubber band assembly and installation of the case, can be adapted to the lateral displacement of 44mm and can reach the normal requirements. d-160 expansion joints | Chaoyang joints | 13833855982 Tong Hao provided by Hengshui Rubber Company.
