The main components shaped steel American Watson (wotson) bridge expansion joint device bridge expansion joints, that edge beam, the beam are made of high-quality corrosion-resistant carbon steel (ie conform to ASTM A-588 standard steel) and manufacturing. Steel Pass CNC turning machine made, pass standard for comparison. Bridge expansion joints rubber seal embedded solid, reliable, waterproof performance d60 bridge expansion joints,, are units of modulus 80mm box-shaped and divided the country in two forms based on a bird-shaped rubber seal shape. The basic structure of the bridge expansion joints and design parameters are: 5-23 and list box as shown in Table 5-10; 5-24 listed and bird-shaped as shown in Table 5-11. Bridge expansion joints Transportation Technology Co., Ltd. Ningbo Lobo products developed using that stretch to use on the highway below 30mm and municipal engineering, seamless situation LB Simple telescopic device structure, the construction is completed, the principle 160 modulus and structural expansion joints, bridge expansion joints after the elastic-plastic-body style formula developed total seamless telescopic device, the principle is established after the company developed a proprietary RS composite elastic rubber material is heated to dissolve into the fluid , poured gravel heated, forming thermoplastic elastomer TCS bridge expansion joints, gravel-type vehicle directly bear loads, bridge expansion joints and grooves on both sides brushing special adhesive to ensure a cross-section of the structure strength. So dedicated special Ingredients RS thermoplastic elastomer composite mechanical properties of rubber. Scope and structure joints, TCS bridge joints filled thermoplastic elastomer for temperature areas, expansion joints of roads and bridges, overpasses and viaducts urban expansion joints, according to the size of the bridge can be divided into two longitudinal i Ergou form. For a total of less than 2% slope bridge for greater than or equal to 2% of the longitudinal bridge 80 bridge expansion joints, bridge expansion joints difference between the two is only whether the set bolts and bars. Research results show that the average temperature of the bridge structure is approximately equal the average temperature of the atmosphere, bridge expansion joints on display in addition to the average temperature of the concrete base of a bridge and then measured the resulting temperature change process and the average bridge, the biggest difference value is only about 1, therefore, to determine the maximum and minimum values ??of the effective temperature of the bridge structure can be converted to determine the highest and lowest values ??of the effective temperature of the atmospheric environment. 160 bridge expansion joints joints _ _ Tianmen reliable quality provided by the manufacturers Hengshui Hao-Hao Tong Hengshui Rubber Company.
