【摘要】：金普广场项目应用抗震楼梯施工技术,在楼梯平台支座处采用钢板及石墨将支座分离使其可以自由滑动,使得剪力、弯矩有效释放,避免楼梯的瞬间破坏。通过优选材料,使其抗震效果更优,支座处滑动板采用镀锌合金钢板,钢板间润滑材料优选为膨胀石墨。在工艺方面预留装修面层,采用C形夹进行临时加固,应用了定型钢模板及定尺钢筋。
[Abstract]:The construction technology of aseismic stair is used in the Project of Kimp Square, and the steel plate and graphite are used to separate the supports of the stair platform so that they can slide freely, so that the shear force and bending moment can be effectively released, and the instant destruction of the staircase can be avoided. The sliding plate at the support is zinc-plated alloy steel plate, and the lubricating material between the steel plates is selected as expanded graphite. The decoration surface layer is reserved for the process, the C-shaped clamp is used for temporary reinforcement, and the formwork and sizing steel bar are applied.
