Hengshui Jinpeng specializing in the production of various models of highway bridge accessories products. The main products are special shaped steel bridge expansion Series: C steel, E-beam, L-beam, M steel, in steel beams, F-beam, I-beam, Z-beam, G type, RG GB steel and other high-quality steel products. Strictly in accordance with the relevant national standards and transportation industry standards organization of production, product quality, service and thoughtful, comprehensive technical guidance, the arrival of fast, all-round protection of your construction schedule and project quality. High-strength steel bridge expansion joints special steel (Sichuan manganese), bridge expansion joints design drawings processing products completely customized according to customers, to ensure product specifications are correct. Bridge expansion joint design points: 1, the overall design is reasonable selected appropriate amount of stretching the gap is extremely important, the greater the gap, the easier telescopic device destruction. Use of the gap is too large or too small, and not considered when installing and adjusting the temperature gap. Especially for laminated rubber telescopic device, easy to damage. Even continuous deck, on the surface layer of pavement also tend to crack. Therefore. To take pre-cut deck, set up the joint, or soft to absorb the pavement cracks, or install a small telescopic device to resolve. In the case of larger longitudinal, if not set up to consider the vertical displacement structure to adapt, but also prone to defects, causing damage. Longitudinal telescopic device along the bridge surface, even a small amount of stretching, there is a large difference between the deflection of the problem, therefore, in the telescopic device is configured to be given attention. 2, telescopic device and other strong beam combined into a whole is undoubtedly important means to improve the effectiveness of their use. Bridge expansion joint device in addition to other types of modulus telescopic device other than a fixed bridge deck, combined with often insufficient, the effect is not ideal, generally small size of the structure, lack of rigidity, and characteristics of new materials, with research is not deep enough, adequate comparative study should therefore make the selection. 3, in order to prevent rainwater leaking into the sky, although in some steel expansion joint device, the matching portion of the inserted rubber seal taken or drainage or pavement level layer as an easy cleaning type, or perfusion across the gap Fill practical type of person waterproof material. Rainwater and deck, should generally be concentrated in the vicinity of the outlet telescopic device is provided; not routine maintenance work on for several painted components, should be of high quality and durable material for protection and effective treatment design. 4, examples of design in terms of design, some designers mistakenly believe that the difference between the actual length of precast slab and the upper structure theory is the length of the ends of the bridge expansion joint width. On a 20m-long hole simply supported beam bridge, for example, some designers scripted, the ends of each with a slit width of expansion joints 2cm. In fact according to the temperature difference between 45 ℃ design, favorable structure. Bridge expansion joints price factors: first beam, I believe we have seen the steel bridge expansion joints, depending on the pass, the price is also different. C, F prices slightly lower, Z, E would be slightly more expensive; second anchor tendons, anchorage tendon length and density all affect the price, because the density increases, increasing the length, then increase the cost of anchoring tendons, anchoring tendons part of the bridge expansion joints, it also affects the price of bridge expansion joints; third pitch, when the pitch is higher, then there will be the king of word and displacement steel box, costs will certainly increase. The fourth tape, under normal circumstances are presented, for the time being can be ignored. The fifth is the logistics information delivery distance, the road will affect the overall long-term product pricing, unless freight customers themselves. The sixth is a bill, invoice and VAT invoice ordinary distinction, this is also part of the impact the bridge expansion joints prices.
