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 edge beam and telescopic displacement, and the gap between each slit substantially uniform, As shown in Figure 5-13. The allocation of the beam and the supporting beam interaction force shown in Figure 5-14. Bridge expansion joints bridge expansion joints, no matter in the case of a few beams Hengshui bridge expansion joints manufacturers, only to set a diagonal support beam in the lower portion of the beam, the pitch is generally oblique supporting beams 1.8m or so, so diagonal support beams make the least number of roots, thereby reducing the size of the displacement of the structure of the control box. This is often the main beam and the main bearings rust and damage, therefore, in the crevice, must be embedded in a waterproof material to prevent leakage, bridge expansion joints Moreover better separated from the base or central railing to make caulking material with sufficient bond, bridge expansion joints to determine the width of the slot reserved for a reasonable, such expansion joints to absorb form filler stretching deformation displacement of the amount of body structure, which is set aside as a telescoping body tank filler beam telescopic should not appear too large bump, even if not exceed the deck height requirements, otherwise it will affect driving comfort, due to the strategy, design and construction should pay special attention. Colors should be coordinated, this expansion joints form, may be used in the deck even village shop where asphalt concrete or cement concrete, joints and elastic-plastic body bridge expansion joints are used in the whole body length RDX multi gqf- c40-type bridge expansion joints, used in the case of asphalt concrete bridge deck is more coordinated sf comb-type bridge expansion joints, but with the use of cement concrete bridge deck where the style, the color is not so on the coordination , so, it is recommended by treatment should be made from the color is very necessary. Because the direction of displacement of the three-dimensional display problems, it should first research and development in order to truly solve the problem. Telescopic device made of three-dimensional deformation of the direction of the Japanese bridge expansion joints mentioned above and in Nanchang, Jiangxi Sima Temple Interchange telescopic device such as a three-dimensional design is a kind of substance. Such targeted designed using telescopic device is relatively safe, this is the main view should be considered in the future, we must also consider the problem as soon as possible, the temperature change of bridge expansion joints, bridge structure exposed in the natural environment, handling a variety of conditions affecting admission, bridge expansion joints seal _ _ Tangshan bridge expansion joints quality of life provided by Hengshui Hao-Hao Tong Rubber Co. project. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
