Bridge expansion joints first steel price factors, 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, tendon anchorage length and density all affect the price, because the density increases, increasing the length, then the increase in the cost of anchoring tendons, anchoring tendons part of the bridge expansion joints, it also affects the price of bridge expansion joints; third pitch, if the pitch is higher, then there will be the king of the word and its displacement steel box, costs will certainly increase. The fourth is a common model, in fact, a lot like RG, RB, comb versions of these models are less common joints, so in general prices are relatively high. Fifth tape, under normal circumstances are presented, for the time being can be ignored. The sixth is the logistics information delivery distance, the road will affect the overall long-term pricing of products, unless the customers themselves bear the freight. The seventh is a bill, invoice and VAT invoice ordinary distinction, this is also part of the bridge expansion joints affect prices. The ends of the bridge expansion joints to prevent water flowing water pier with a rubber seal inside the head can be set at both ends of the expansion joint device Alice, Alice head joints device according to different pavement design different styles (length and tilt angle), Alice head generally placed inside the barrier wall. Damaged bridge expansion joint device due to reasons set in the weak end of the beam structure of the site, the direct effect of the vehicle to withstand repeated loads, and there are exposed to nature, subject to various natural factors, therefore, telescopic device is easily damaged, difficult repair site. Breakage of bridge expansion joints reasons are many, are: ill-designed bridge expansion joints bridge expansion joints designed beam ends failed to consider carefully, in repeated loads, damage caused by the beam end telescopic device failure. Moreover, sometimes deformation amount calculating inappropriate, excessive use of a telescopic pitch, resulting in breakage of telescopic device. Bridge expansion joint problem telescopic expansion joint device itself insufficient member strength anchoring device itself insufficient structural rigidity, resulting in varying degrees of damage in the operation process. Telescopic device after pouring pressure filling material is not taken seriously, carefully selected, resulting in lower quality telescopic device operating, resulting in varying degrees of disease. Construction of bridge expansion joints and pouring the construction process, the beam end joints spaced no completed according to design requirements, artificially zoom in and out, positioning angle position is incorrect, resulting in telescopic device is not working properly. Thus, the following occurs: Because distance is too small joints, rubber expansion joints due to overrun squeeze arising Bump bump; the seam away from excessive shear loads and vehicles traveling under inertia, will loose Rubber expansion joints with a position angle, producing another type of jumping. Telescopic device anchoring steel welded construction is not strong enough, or produce the phenomenon of missing embedded anchor bars, joints itself to cause problems; well, after pouring a bad bridge deck expansion joint telescopic device installed during construction, During use, the joints under cyclic loads causing damage. Bridge expansion joints set is not perfect continuous seam joints in order to reduce a large number of continuous beam or continuous deck. Continuous deck would need to set up a continuous seam, continuous seam setup is not perfect, resulting in a continuous seam damage, arising from the bridge jumping. Continuous deck joints, deformation fake seam width and depth enough to set standards, not uniform, which to varying degrees, affect the normal operation of a continuous seam. www.htgcxj.com
