Anti-seismic staircase with sliding bearing and its construction method

Abstract

The invention discloses anti-seismic stairs with a sliding support and a construction method thereof. The anti-seismic stairs with the sliding support are characterized in that the anti-seismic stairs with the sliding support comprise an upper platform (1), a stair bench slab (2) and a lower platform (3) which are connected in sequence, the lower platform (3) is connected with the lower end of the stair bench slab (2) through the sliding support, and the sliding support comprises a first sliding pad layer (10) and a second sliding pad layer (11). The anti-seismic stairs with the sliding support is provided with the sliding support, and has the advantages of being high in seismic resistance capacity, extremely low in friction coefficient, free of maintenance, strong in adaptability, resistant to friction and long in service life, high in bearing capacity, simple in structure and convenient in construction. The construction method has the advantages that construction procedures are few, operation is easy and convenient, and the anti-seismic capacity of stairs and a main body structure can be improved greatly.

Description

technical field [0001] The invention relates to an anti-seismic staircase with a sliding support and a construction method thereof, belonging to the technical field of building structural components and building construction. Background technique [0002] Reinforced concrete slab stairs are one of the most widely used staircase construction forms in buildings. However, this type of cast-in-place reinforced concrete staircase built in the traditional way is poured together with the upper and lower supporting members. The stair slab is used as an oblique member to participate in the lateral force resistance work, which increases the rigidity of the main structure and leads to uneven distribution of rigidity in the floor plane. , has a great impact on the overall analysis results of the structure; and this approach often leads to the stairwell becoming the first anti-seismic defense line of the structure, which will be destroyed first under strong earthquakes. Rescue function....
