The shock-absorbing staircase with steel-concrete composite structure sliding support and the construction method thereof of the present invention belong to the field of stairs, and the staircase includes a steel ladder column, a steel ladder beam, a stair rest platform plate and a stair tread plate, and the stair rest platform plate and the stair tread plate For cast-in-place reinforced concrete structural slabs. The cast-in-place reinforced concrete structure and the stair facing bricks are bonded with mortar, which is convenient for construction, beautiful in effect, and not prone to common quality problems such as hollowing. The top of the stair tread plate and the stair rest platform plate at the upper end are integrally cast and formed, and the bottom and the stair rest platform plate at the lower end are slidingly connected by a polytetrafluoroethylene sliding plate. The invention uses steel beams and steel columns reliably connected with the main steel structure to form an independent stairwell steel frame, which reduces the impact of earthquake force on the stairs, has a high energy dissipation and shock absorption effect, and also forms a shock isolation layer between the upper and lower stair sections . There is a sliding connection between the stair rest platform board and the stair steps, which reduces the resonance effect of people walking and running.
Description
technical field [0001] The invention relates to the field of stairs, in particular to a shock-absorbing staircase with a steel-concrete composite structure sliding bearing and a construction method thereof. Background technique [0002] With the rapid development of urbanization, the application of steel structure prefabricated buildings is becoming more and more extensive. Most of the existing steel structure stairs are directly installed steel ladder beams, steel rest platforms and steel steps on the main steel structure. This steel staircase is formed in the processing plant and transported to the construction site for installation. However, when the rest platform and steps are all steel structures, the bonding between the decorative bricks and the steel plates is not firm, and hollowing is prone to occur. Moreover, the rigid connection between the steel rest platform and the steel frame will lead to weakened seismic performance and the resonance of pedestrians will redu...
