XF-type bridge expansion joint device bridge expansion joints are oblique-bearing bridge expansion joint device is determined by the Ministry of Railways Institute of Railway Construction, Hebei Hengshui City Rubber Co. and Shijiazhuang Traffic Survey and Design Institute jointly developed in 1993 in The Modular series. Bridge expansion joints and structural features principle: bridge expansion joints, mainly by the edge beam, the beam, the sealing rubber band, diagonal support beams, bearing pressure and compression, displacement control box and anchor steel components. Its edge beam and shaped steel beams using domestic extrusion. Its cross section is arranged as shown in Figure 5-12. In construction, if the use of the heated material waterproof seams, then stuffing the nature of matter is likely to be affected, therefore, bridge expansion joints is best to use room temperature water poured into the joint material type, when forced to use the heating, to make may make it low, and to give full attention not to damage the stuffing. Bridge expansion joints. Telescopic crevice stuffing d60-type bridge expansion joints, stretching the gap for stuffing materials mainly to prevent leakage off the seam, it should have a waterproof and resistant to stretching of nature, and to keep the seam reaches the maximum gap width, thickness at its understanding in compression direction as well, all with style stuffing waterproof material like foam rubber and previously used, should not have taken sufficient initial compression that can not maintain its function as a bridge expansion joints, design, needs full attention on construction, furthermore, in the case of stuffing in tension, if defective, it becomes very fragile, railings or central processing base with separate part of the base and the central median railing processing phase section . Railings and median strip connecting the base part, it should be made stuffing tortuous, watertight structure. Temperature changes, the bridge structure is exposed in the natural environment, bridge expansion joints handling the effects of various natural conditions. Which affected the absorption of various natural conditions, in which release of solar heat, ambient air temperature fluctuations and atmospheric flow and other factors, the temperature of the bridge structure in constant change, while gqfc40 type bridge expansion joints, bridge structures admission the outer surface of the bridge expansion joints through reflection, against radiation, convection air bridge expansion joints and are subject to the impact of the time engaged in the exchange of heat capacity, the temperature change of the bridge structure in Australia depends on the following factors, bridge the geographical latitude, season and moments of sunshine wall toward the bridge expansion joints and the sun azimuth cd40-type bridge expansion joints, atmospheric transparency, thermal properties of materials bridge structure, the bridge outside the structure and color of the surface roughness. gqfc40 type bridge expansion joints, Henan bridge expansion joints, the manufacturers provided by Hengshui 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. The company better work attitude and continuous improvement through innovative ideas will lead Hao engineered rubber and you work into the brilliant, for a better future!
