Amount of stretching the scope and design of the technical parameters specifications series products for bridge expansion joints 0 ~ 1040mm. Bridge expansion joints installed reserve notch size, type and design parameters of d-type bridge expansion joints, listed as shown in Figure 5-6 and Table 5-2. Bridge expansion joints of power transmission principle is parallel to the direction of the beam bridge joints, while the beam direction at a certain angle and diagonal seams supporting beam and displacement control box telescopic device supporting transmission mechanism, that is, when the beam phase When connected to one side of the beam expansion, expansion joints staggered diagonal support beams and the beam angle changes, and in the same direction 梁发生 and side beams stretching displacement gqf-c60 bridge expansion joints, and make each slit the gap between the basic uniform, shown in Figure 5-13. The allocation of the beam and the supporting beam interaction force shown in Figure 5-14. Bridge expansion joints, in the matter of a few beams, the only set a diagonal support beam in the lower portion of the beam, the pitch is generally oblique supporting beams around 1.8m, it can root diagonal support beams minimum number, thus reducing the size of the displacement of the structure of the control box. gqfc type bridge expansion joints, bridge expansion joints in Xinjiang, a professional manufacturer provided by Hengshui HaoTong Rubber Company.
