13833855982,40 price type expansion joints, expansion joints Fingers HaoTong by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) is a professional, "grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical steel bearing" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "Hao Tong" brand has a good reputation. We adhere to the "service first, customers first" principle, so ho-engineered rubber has won the trust of customers in the public site construction materials, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! American Watson (Wotson) means a bridge expansion joints, bridge expansion joints support systems: support beam supporting the bridge expansion joint device on the brake can be buffered the impact of elastic support, so that deflection move the entire structure is easy to adjust. Beams located in each respective group support beam 40 type joints prices, expansion joints and rigid connection (Figure 5-22). Thus, fixed to the support beam in the horizontal beam when subjected to the braking force is not inclined 80 type steel expansion joints, due to the support beam as a basis for the entire assembly to form a very stable grid structures. 2, bridge expansion joints displacement control system: the telescopic device between the root support beam bearing boxes are installed polyurethane foam control spring, they can slip from one application to the other side, when the device is opened to the maximum extent, bridge expansion joints produced the greatest pressure control spring. Conversely, when compressed to a minimum clearance, i.e. the control spring is fully relaxed, the span adjustment, etc. to achieve the purpose, as shown in Figure 5-26. 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 for the next growing form of transportation, research and test work in this area should be put on the agenda class mall. For a particular three-dimensional telescopic device can meet certain range vertical, horizontal and vertical stretching deformation, but taking into account processing, there gqff80 type bridge expansion joints installed accuracy error condition, it generally refers to the telescopic device taking into account the need to design longitudinal deformation bridge expansion 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.
