Bridge expansion joint: refers to the bridge deck deformation requirements, usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridgeexpansion joints。 It is required that the expansion joint can be freely expanded and contracted in both directions parallel and perpendicular to the bridge axis, firm and reliable, and the vehicle should be smooth when driving smoothly, without jumping and noise. it should be able to prevent rainwater and garbage and soil from seeping into and blocking; Installation, inspection, maintenance, and elimination of dirt should be simple and convenient. At the place where expansion joints are set, the railing and the bridge deck pavement must be disconnected.
The function of bridge expansion joints: it is to adjust the contractorVehicle loadand the superstructure caused by the bridge building materials. Once the telescopic device of the diagonal bridge is destroyed, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents.
Price influencing factors
The first type of steel, I believe everyone has seen the section steel of bridge expansion joints, and the price is also different according to the different hole types. C and F prices are slightly lower, and Z and E are slightly more expensive;
The second anchor bar, the length of the anchor bar and its density affect the product price, because the density increases and the length increases, then the cost of the anchor bar increases, and the anchor bar is part of the bridge expansion joint, so it also affects the price of the bridge expansion joint;
The third spacing, if the spacing is higher, then there will be kingzigang and its displacement box, and the cost will definitely increase.
Fourth, whether it is a common model, in fact, many like RG, RB,Comb toothboardThese expansion joint models are less common, so the price will generally be higher.
The fifth rubber strip is generally given away and can be ignored for the time being.
The sixth delivery distance is the logistics information, and the long distance will affect the overall quotation of the product, unless the customer bears the freight by himself.
The seventh is the bill, ordinary invoice andVATThere is a distinction between invoices, which is also part of the impact on the price of bridge expansion joints.
