Assembly type shock insulation stair substructure in multi-layer frame structure
The invention discloses an assembly type shock insulation stair substructure in a multi-layer frame structure, which is formed by integrally connecting a plurality of upper and lower layers of staircases in the multi-layer frame structure, the bottom of the assembly type shock insulation stair substructure is supported in a frame beam of a top plate of the multi-layer frame main body structure through a shock insulation support, and a shock insulation seam is formed between the vertical face of the assembly type shock insulation stair substructure and the peripheral main body structure. Vertical isolation seams are formed between the top and the bottom of the assembly type shock insulation stair substructure and the main body structure correspondingly. A plurality of layers of staircases in a frame structure are independent from a main body structure, necessary through staircase columns are added to form an independent staircase sub-structure, a seismic isolation support is introduced to a bottom layer or a basement top plate, and the rigidity of a staircase frame sub-structure is increased by fully utilizing the supporting effect of a staircase inclined staircase plate and the rigidity effect of a filling wall; the earthquake isolation effect of the stair substructure is enhanced, the earthquake force of the earthquake isolation stair is reduced, and stair damage is greatly reduced.
本发明公开了一种多层框架结构中的装配式隔震楼梯子结构，所述装配式隔震楼梯子结构由多层框架结构中的上下多层楼梯间连接成整体构成，所述装配式隔震楼梯子结构的底部通过隔震支座支承于多层框架主体结构顶板的框架梁中，所述装配式隔震楼梯子结构的立面与周边主体结构之间设置有隔震缝，所述装配式隔震楼梯子结构的顶部和底部与主体结构之间分别设置有竖向隔离缝。通过将框架结构中几层楼梯间从主体结构中独立出来，增加必要的贯通梯柱形成独立的楼梯子结构，并在底层或地下室顶板引入隔震支座，充分利用楼梯斜梯板的支撑效应、填充墙的刚度效应增加楼梯框架子结的刚度，增强楼梯子结构隔震效果，降低隔震楼梯的地震力，大幅度减少楼梯破坏。
