Tooth plate joints, Hao-engineering rubber, 160 comb plate provided by the manufacturer of expansion joints HaoTong Engineering Rubber Co., Ltd. Hengshui. Tooth plate joints, Hao-engineering rubber, 160 comb plate expansion joints manufacturer Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call this page Contact phone or on the picture to obtain the latest information, contact: Liu. With the rapid development of China's economy, the supply of 120-type comb plate joints to the highway as the representative of the highway sprung up, a sharp increase in road traffic bridge expansion joints, axial travel of the vehicle speed and the vehicle on the road focusing on growth, people driving comfort and other requirements are also increasing, and therefore insufficient attention to issues related to the bridge expansion joint device design and construction in the past, bridge expansion joints becomes a more prominent, forcing the bridge design, construction, conservation and management departments are to be fully appreciated. Bridge expansion joints, like other bridges affiliated members, with the need to bridge technological advances and applications of new varieties emerging, all aspects of performance has been further improved. Engineering Rubber Co., Ltd. Hengshui Hao-over design and production of various types of domestic and international commercialization of bridge expansion joint device, bridge expansion joints for many years after the actual project has been fully reflected in their characteristics and shortcomings, and to summarize the past On the basis of experience, continuous improvement and perfection, quality of products is also rising. SG-type bridge expansion joint device bridge expansion joints, is by the Shanghai Municipal Engineering Design Institute, Shanghai Rubber Factory Rubber Factory and Hunan Provincial Road and Bridge Company in 1991 jointly developed Modular bridge expansion joint device products. Characteristics and principles of bridge expansion joints constructed bridge expansion joints consist of two basic components: a bridge structure across - the beams across the gap joints to withstand dynamic loads XF80 type comb plate joints vehicle and passed to the bridge structure; in the middle of I-shaped steel beams - in the middle between the side beams and beam or beams of the two middle gusset plate joints tooth structure, the neoprene gasket unit into a position parallel to the expansion joints, bridge joints are formed in the form of a continuous structure of the spacer layer. The device uses ordinary beam made of separate beams, steel beams in the top split of a recessed plate 160 comb plate expansion joints manufacturer, it is linked with the cover with high strength bolts form the rubber molding ( bird-shaped) fastening position. Activities beams with a thickness of 15 ~ 28mm steel plate welded and heat-treated to eliminate welding stress, which is arranged pitch 1.5mm.
