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 Even when one side edge of the telescopic beams, support beams and bridge expansion joints staggered oblique angle changes in the beam, and side beams in the same direction with 梁发生 telescopic displacement, and the gap between each slit substantially uniform cqf -c40 type bridge expansion joints, 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. On the current domestic situation, bridge expansion joints can be said that tests all products are not doing a decent fatigue and seismic performance of the project. This is compared with foreign countries have better characteristics, compared with foreign countries in this regard have a big gap, bridge expansion joints form of transportation for the next growing gqf-z-type bridge expansion joints, experimental research work in this area should mention Mall on the class schedule. For a particular three-dimensional telescopic device can meet certain range longitudinal bridge expansion joints, horizontal and vertical stretching deformation, but taking into account the processing accuracy error condition occurs installation, you generally refers to taking into account the need to design telescopic device longitudinal deformation, the bridge joints should also be horizontal and vertical has its adaptability. Similar modulus telescopic device, through the post to find out for certain simulations have a certain amount of horizontal and vertical range of adaptation, so that only the construction and installation of processing activities appear unforeseen error, bridge expansion joints as long as the error value in its allowed within the range that does not appear to have failed and the risk of not working, so the request can not say it is not an impossible, but in terms of the safety of these products, we should say is a necessary margin. Shallow-type bridge expansion joints | Heilongjiang bridge expansion joints | manufacturers have stock HaoTong provided by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co.
