Description
Technical field
The utility model relates to the precast stair field in precast reinforced concrete construction.
Background technology
Precast reinforced concrete construction is installed at the scene by the prefabricated units of plant produced to form, and has and save field workforce, short construction period, be convenient to the advantage such as industrialization and mechanization production.At present, the building trade of home and abroad all more and more payes attention to precast reinforced concrete construction, be studied in prefabricated post, precast beam, precast plate and prefabricated node etc., basic Precast Concrete Frame system can be formed, but, also need a kind of prefabricated reinforced concrete stair, play vertical traffic and evacuation effect.On the other hand, find in earthquake disaster investigation that the stair of reinforced concrete frame structure damage comparatively serious, stair assume responsibility for larger horizontal force in earthquake, in " seismic design provision in building code ", regulation should take construction measure, reduce staircase component to the impact of agent structure rigidity, also reduce stressed when earthquake of stair, guarantee the safety of stair, prefabricated reinforced concrete stair also will meet the requirement of earthquake resistant code simultaneously.Current assembled steel reinforced concrete frame structure system is perfect not enough, needs a kind of prefabricated reinforced concrete quakeproof stair.
Summary of the invention
In order to solve the vertical traffic problems of precast reinforced concrete construction, and meet the requirement of earthquake resistant code, the utility model discloses a kind of prefabricated reinforced concrete quakeproof stair, and stair have the advantages such as component is simple, power transmission is reliable, anti-seismic performance is good.
The technical solution of the utility model is: be made up of waist slab, platform support member, outside landing beam, inner side landing beam, brace summer, polyfluortetraethylene plate, weather strip, inverted L-shaped plate, Vierendeel girder, side column and center pillar.Waist slab side is for marking time, and opposite side is platform, and the end of marking time of waist slab is fixed on brace summer, and platform end is overlapped on outside landing beam and inner side landing beam, and the contact position of waist slab platform end and outside landing beam and inner side landing beam arranges polyfluortetraethylene plate.Gap between two pieces of waist slab platform ends, the gap between waist slab platform end and side column adopt weather strip shutoff.The jag of inverted L-shaped plate is fixed on brace summer, and planar ends is fixed on Vierendeel girder.Outside landing beam is fixed on side column, and Vierendeel girder is fixed on center pillar, and platform support member is fixed on side column and center pillar.Inner side landing beam is fixed on the short column of platform support member, and brace summer is fixed on the crossbeam of platform support member.Being fixedly connected with of staircase component beam-column all adopts groove and tognue type to connect, and supporting member leaves convex raft, is stayed epirelief raft by supporting member, arranges pre-embedded steel slab at epirelief raft and lower convex Cha Chu, is coupled together by component by welding.Epirelief raft is stayed at platform support member two ends, corresponding with the lower convex raft of side column and center pillar; Side leaves convex raft, corresponding with the epirelief raft of brace summer; Top arranges short column, short column leaves convex raft, corresponding with the epirelief raft of inner side landing beam.Epirelief raft is stayed at landing beam two ends, outside, corresponding with the lower convex raft of side column.Epirelief raft is stayed at landing beam two ends, inner side, corresponding with the lower convex raft on platform support member short column.Epirelief raft is stayed at brace summer two ends, corresponding with the lower convex raft on platform support member crossbeam.Epirelief raft is stayed at Vierendeel girder two ends, corresponding with the lower convex raft of center pillar.Side column leaves multiple lower convex raft, corresponding with the epirelief raft of platform support member and outside landing beam respectively.Center pillar leaves multiple lower convex raft, corresponding with the epirelief raft of platform support member and Vierendeel girder respectively.
The platform end of waist slab is overlapped on outside landing beam and inner side landing beam, and polyfluortetraethylene plate is set in the contact position of waist slab platform end and outside landing beam and inner side landing beam, simultaneously, between two pieces of waist slab platform ends, between waist slab platform end and side column, leave gap, so waist slab and outside landing beam and inner side landing beam energy relative sliding, when reducing earthquake, staircase component is stressed, is conducive to the antidetonation of stair and agent structure.
The utility model component is simple, power transmission is reliable, waist slab and landing beam energy relative sliding during earthquake, and when reducing earthquake, stair is stressed, is conducive to the antidetonation of stair and agent structure.When the utility model can reduce earthquake, the earthquake of precast stair, guarantees stair safety, has larger social benefit.
