Force transmission principle z60 type bridge expansion joints bridge expansion joints, and 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 support transmission telescopic device that, when connected to the beam phase one side beams stretching d80-type bridge expansion joints, bridge expansion joints staggered diagonal support beams and beam angle changes in bridge expansion joints, and in the same direction 梁发生 the edge beam stretching displacement, and the gap between each slit substantially 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 The minimum number of z80-type bridge expansion joints, thereby reducing the size of the displacement of the structure of the control box. Bridge expansion joints bridge expansion joints, is a 1993 combined with our transportation industry standards "highway bridge rubber expansion device" developed modulus telescopic device products. The product has completed expansion volume 80 ~ 2000mm range series design, bridge expansion joints for the use of various types of new bridges, but also for the telescopic device to replace the old bridge into the selection. The product is even chain-link mechanism, bridge expansion joints with good stretch uniformity, and won in 1999 the Ministry of Communications Science and Technology Progress Award, detailed relevant GQF-MZL type telescopic device description, see Hengshui HaoTong Product Manual. Its reserve tank and locate the typical cross-section of the joist reserved slots as shown in Figure 5-16 and Figure 5-17, the corresponding series of design parameters and specifications listed in Table 5-6. z80-type bridge expansion joints, bridge expansion joints, Guizhou, procurement Hao-borne freight provided by Hengshui HaoTong Rubber Company. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
