网架减震橡胶垫块价格
网架橡胶支座是为适应现代建筑需要的一种板式橡胶支座产品，解决大跨度结构因温度变化而产生的水平位移和建筑结构之间的隔震、减震要求而设计的。网架橡胶支座是由多层橡胶片和多层加劲钢板经加压、硫化制成，具有足够的竖向钢度，以支撑上部结构的垂直载荷。同时，通过其良好的弹性和较大的剪切变形，来满足上部结构因温度变化而引起的支撑结构的推力，并通过网架橡胶支座的耗能起到减震、隔震作用。网架橡胶支座定位通孔，通过螺栓将支座固定在支撑结构上。
The grid rubber bearing is designed to meet the needs of modern architecture as a plate rubber support product, which solves the horizontal displacement caused by temperature change and the isolation and shock absorption requirements between the large-span structures. The rubber bearing of the grid frame is made of multilayer rubber sheet and multilayer stiffened steel plate, which is made by pressing and vulcanizing, and has enough vertical steel degree to support the vertical load of the superstructure. At the same time, through its good elasticity and large shear deformation, it can meet the thrust of the supporting structure caused by the temperature change of the upper structure, and it can play the role of shock absorption and isolation through the energy dissipation of the rubber bearing of the grid. The rubber bearing of the net frame is positioned through the hole, and the support is fixed on the support structure by the bolt.

橡胶支座的正确就位先使支座和支承垫石按设计要求准确就位。架梁落梁时，T型梁的纵轴线要与支座中心线重合；板梁、箱梁的纵轴线与支座中心线相平行。为落梁准确，在架第一跨板梁或箱梁时，可在梁底划好二个支座的十字位置中心，在梁的端立面上标出两个支座的位置中心线的铅直线，落梁时使之与墩台上的位置中心线相重合。
The correct position of the rubber bearing first makes the support and bearing stone in place according to the design requirements. The longitudinal axis of the T beam should coincide with the center line of the support, and the longitudinal axis of the plate beam and the box girder is parallel to the center line of the support. For the first frame in the fall beam accurately, cross slab beam or box girder, cross the center position can be marked two supports at the end of the beam, the lead line and mark the position the center line of two bearings in the end elevation on the beam, beam falling when the phase coincides with the position of the center line on the pier.
以后数跨可依照第一跨梁为基准进行。在架梁落梁时要平稳，防止压偏或产生初始剪切变形,大家可以参考铁路桥梁板式橡胶支座规格表 。在安装T型桥梁时，若橡胶支座比梁筋底宽，则应在支座与梁筋底之间加设比支座大的钢筋混凝土垫块或厚钢板做过渡层，以免支座局 部受压，而形成应力集中。钢筋砼垫块或厚钢板要用环氧树脂砂浆和梁筋底贴合粘结。落梁后，一般情况下橡胶支座顶面与梁面保持水平。预应力简支梁，其支座顶面可稍后倾；非预应力梁其支座顶面可略微前倾，但倾斜角度不得超过5"。
The future span may be based on the first cross beam. When the beam is falling, it should be stable to prevent the pressure deviation or to produce the initial shear deformation. We can refer to the gauge table of the plate rubber bearing of the railway bridge. When installing the T type bridge, if the rubber bearing is wider than the bottom of the beam reinforcement, a reinforced concrete cushion or thick steel plate with larger support should be added as the transition layer between the support and the bottom of the beam, so as to avoid the partial compression of the support and form the stress concentration. The reinforced concrete mat or thick steel plate should be bonded with the epoxy resin mortar and the bottom of the beam. After the falling beam, the top surface of the rubber bearing and the beam surface is kept in general. The top surface of the prestressed simple supported beam can be tilted later, and the top surface of the non prestressed beam can be slightly forward, but the angle of the tilt should not exceed 5 ".
