Supply [Heze, Weihai] GPZ pot rubber bearing, pot rubber bearing price, model Junteng supply inquire [Ms. Peng]

Pot rubber bearing company, state certified exemption, inexpensive, pot rubber bearing 1, Overview pot rubber bearing structural principle is placed in a the sealed steel pot rubber block, in the three-way the case of the force, while generating a reaction force to withstand a vertical load of the bridge, the same time, using the elasticity of rubber to meet the rotation of the beam end, by welding or in the free-slip the Theravada board a stainless steel plate with the PTFE, to complete bridge the horizontal displacement of the upper structure. This series of products has a reasonable structure, large carrying capacity, deformation, horizontal displacement of large, flexible rotation, and the good performance of the buffer, the best stand of the continuous building bridges, pot rubber bearing [1] and has The light weight, compact structure, simple structure and low building height, easy to manufacture, save steel, reduce cost, etc., suitable for large collapsed bridge better bearing. Used GPZ GPZ (II), GPZ (KZ) three categories. The series bearing GPZ (II) the current carrying capacity of 31 levels bearing capacity 0.8MN-60MN, to meet the needs of large build bridges. GPZ (II) in the standard series, the fixed bearing seat in each direction and a one-way activity level of the non-slip direction bearing Caine to 10% of the carrying capacity of the bearing capacity of not less than. The seismic bearing horizontal bearing capacity bearing Kennedy to 20% of the carrying capacity of not less than. The bearing rotation angle of not less than 0.02rad. 5201 silicone grease lubrication, the ambient temperature the movable bearing design friction coefficient minimum take 0.03; 5201 silicone grease lubrication after cold type the movable bearing design friction coefficient minimum take 0.06 . 2, pot rubber bearing classification used highway pot rubber bearing Model: GPZ pot rubber rubber bearing and rubber bearing (based on the GT391-1999) GPZ (Ⅱ) pot rubber, GPZ (KZ) basin-type several departments such as rubber bearings each category according to the displacement form can be divided into three kinds of fixed (GD), unidirectional activity (DX) and two-way activity (SX). 3, install the the anchor column installed in bearing backplane four corners. 2, pouring bearing buttresses, leaving the top section of height, leaving bigger height than the seat anchor column; 3, bearing crane to the top of the pad stone correction plane position and height; 4, concrete pouring pad stone ; 5, 4 mounting stand upper anchor post; 6, installation of cast-in-place beam template, lashing the cast-in-place beam reinforced; 7, pouring concrete beam; 8, remove the bearing on both sides of the temporary connection. The rubber bearing damage causes and replacement programs, bearing damage cause analysis (1) bearing material is uneven, the individual bearings using recycled rubber. (2) the installation of the part of the sliding bearings not apply grease oil, leading skateboard bearing shear damage. Support pad stone elevation control is not good (3) the installation process, the monolithic beam four uneven force by force bearing balancing individual rubber bearing separation, leading to a larger force bearing deformation beyond the prescribed value. (4) structural expansion joints is not completed, the traffic is not completely closed, bearing the shear stress, resulting in damage to the part of the social heavy vehicles through brake. Second, the replacement program (1) bracket the basis of tonnage jack jacking bridge span for ease of mounting bracket and to provide adequate support for capacity, reinforced concrete foundation to be set under the bracket. Bracket base are in the river, the foundation is relatively weak, low bearing capacity and uneven. The foundation placed will produce a large amount of differential settlement. Reinforced concrete foundation must be increased in order to reduce the settlement amount, size, and stent preload. This program works a large amount of longer duration, low security and high cost. (2) the use of ultra-thin one-way jack pier top and dial indicator with the support from the top of the bridge span the full use of beam and pier top space, ultra-thin one-way to the jack support Tun top, jacking up the bridge span, with a height of 70 mm, Φ = 300mm circular flat hydraulic jack (the largest top-liter weight of 250t, the maximum stroke of 15 mm) in parallel with the electric oil pump bridge span jacking using the speed dial indicator observation beam-up to ensure that the bridge span each beam force uniform. [4] define bearing means for supporting the weight of the container or equipment, and it is fixed at a certain position of the support member, but also to withstand the vibration and earthquake loads in operation. Rubber bearing rubber and steel sheet close combination used to support the bridge weight.
