Intermediate plate: intermediate plate located between rubber sheets and PTFE plate, the middle plate protruding below and embed the groove bottom basin, with a diameter slightly smaller than the diameter of the tank in order to ensure the flexibility of rotation, leaving the top surface of the steel plate to the middle PTFE sheet front slot, PTFE plate and stainless steel plate, while bearing activities by relative sliding PTFE sheet and stainless steel plate to meet the needs of the bridge displacement, so the absorption requirements Matcha between them as small as possible. PTFE sheet thickness is 4-8mm, part of the plate thickness (generally not less than 2.5mm) plates embedded in the middle of the top surface of the reserved slot, should be higher than the rest of the top surface of the intermediate plate is about 1.5-3mm, to ensure that the stainless steel plate slidable seal, the use of an annular ring, can also be used POM, PTFE, and stainless steel ring is filled, but it is basically in the sealing rubber plate-shaped body, and prevent the aging of the rubber sheet and the extrusion plate, pots style kids usually do after steel roof above the welding equal to or greater than 2mm thick stainless steel plate ah construction hinge bearings, bearing strength of its thickness depends on the support of local materials. The thickness of the flatness of the top plate is of stainless steel has a direct impact on the guarantee. As the roof fixed bearing can be processed from the middle of the whole plate, but also the intermediate plate after plate and can be processed separately welded together. Checking steel pots ring stress tension of steel bowl ring, radial design level design activities hinge bearing internal forces, the design level resistance, rubber sheet under pressure to produce, design vertical force, rubber plate design thickness, horizontal force generated design internal forces, longitudinal horizontal force generation design internal forces, internal forces transverse horizontal steel compressive forces generated design standard values, partial safety factors, the recommended value, rubber board area, bottom basin ring diameter, the inner diameter of the ring bottom basin, basin bottom ring height, steel pots withstand shear ring. Bottom basin ring radial force designed to withstand the shear design value, the bottom bowl ring design value of shear strength, compression produced rubber sheet, rubber sheet level to produce shear design value, compressive strength steel standard values, partial safety factors recommended value of 1.10, the bottom basin ring diameter, bottom diameter pots yellow, steel bottom plate pelvic floor tension design value, the tensile strength of steel at the end of the pelvic floor plate design value, steel bottom basin vertical force design value, compressive strength steel standard values design strength allowable value is generally taken to be 140mpa, sub-factor of safety items. Pelvic floor plate steel ring bearing universal joints to the area, the outer diameter of the ring of steel pots, steel plate thickness hinge support the pelvic floor, on the roof or in the middle and bottom steel bowl ring contact checking, assuming that the width of the roof on a fast connection surface, then the commercial roof or intermediate bottom and the bottom bowl ring contact surfaces can be designed to the average of the contact surface of the mechanical resistance should be carried out to verify the basic role of the combination. Planar contact surface checking. Plane contact force design value, the roof plane contact strength design value, the compressive strength of steel materials analysis coefficient standard values ??recommended value, the steel basin ring diameter, the height of the ceiling height in contact with the basin ring, curved contact surface of the radius of curvature R Hao Through engineering rubber, activities hinge bearing, Haikou hinge support provided by Hao-engineering rubber.
