Rubber cushion plate of space truss is often used for jointswithout pull-out re It has the functions of verticalbearing and vertical turning angle under external force andhorizontal shearing resistance. The rubber cushion plate of spacetruss is made of multi-layer rubber sheet and stiffening steelplate by heating and vulcanizing under pressure. It hasconsiderable vertical stiffness and vertical bearing capacity, sothat it can support the load entrusted by the upper member and passthrough the cushion under stress. The energy dissipation caused bythe local deformation of the plate plays a role in reducing thevibration. The support is fixed by bolts through the bolt holes,and the upper and lower components are fixed by bolts. The rubbercushion plate of the space truss has a certain function of verticalturning angle, and there is no horizontal displacement.
主司竖向减震之功能；因为有螺栓限位，不考虑垫板的水平剪切。网架橡胶垫板适用于竖向承载力不超过4000KN的网架结构。网架橡胶垫板结构简单，易于安装，更换和养护，造价较低。
The main function of vertical shock absorption is that thehorizontal shear of cushion plate is not considered because of thebolt limit. The rubber pad is suitable for the grid structure withvertical bearing capacity not exceeding 4000KN. The rubber pad ofspace truss has the advantages of simple structure, easyinstallation, replacement and maintenance, and low cost.
网架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，并通过网架支座的耗能起到减震、隔震作用。网架支座定位通孔，通过螺栓将支座固定在支撑结构上。
Space truss support is designed to meet the needs of modernbuildings as a kind of plate rubber bearing product, which cansolve the horizontal displacement caused by temperature changes oflong-span structures and the re of isolation and shockabsorption between buildings. The space truss support is made ofmulti-layer rubber sheets and multi-layer stiffening steel platesby pressure and vulcanization, and has sufficient vertical steeldegree to support the vertical load of the superstructure. At thesame time, through its good elasticity and large shear deformation,it can satisfy the thrust of the supporting structure caused by thetemperature change of the upper structure, and play the role ofshock absorption and isolation through the energy dissipation ofthe grid support. The support of the space truss is positionedthrough the hole, and the support is fixed on the support structureby bolts.
