Abstract
The utility model discloses a beam type anti-seismic stair, which comprises a middle layer stair part and a bottom layer stair part, wherein the middle layer stair part comprises a middle floor beam I, a middle stair beam II and a middle floor beam III which are arranged in sequence from top to bottom; a gap is formed between the middle floor beam III and the middle stair beam II; the middle floor beam III is further provided with a bridging piece; the middle layer stair part further comprises a middle floor board. The stair which can be applied to different positions and is good in anti-seismic effect is designed specific to different stress conditions of the middle layer and the bottom layer of a building, so that the aim of achieving seismic performance can be fulfilled by means of a sliding support, the specially-designed bridging piece and a floor thick board once in case of an earthquake. The beam type anti-seismic stair has the advantages of good anti-seismic effect, convenience in implementing and low cost.
Description
Technical field
The utility model relates to building house technical field, especially relates to a kind of stringer type stairway with anti seismic efficiency.
Background technology
At present, stair generally adopt stair stringer and the integrated poured scheme of platform, and when the maximum drawback of this scheme is earthquake, the diagonal brace system of stair has absorbed very large seismic forces, easily causes the breaking-up of stair or collapses, and then having affected passway for escaping safety.
Application number is CN201220343517.7, title is in " a kind of stringer type stairway with antishock device ", to disclose a kind of stair of tool anti seismic efficiency, these stair comprise stair stringer, stage support, stair stringer is arranged at the top of stage support, between stair stringer and stage support, leave predetermined gap, in order to reach antidetonation object, these stair are provided with antishock device especially, this device comprises two block plates, wherein a block plate is fixedly connected on the bottom surface of stair stringer, another block plate is fixedly connected on the end face of stage support, between two block plates, there is sliding layer, this sliding layer is made by pitch or graphite.These stair are by means of sliding layer, by steel plate, with respect to stage support, produce and slide, thereby the stair distortion and the damage that in earthquake, cause have been avoided, make stair comparatively safe, but this antidetonation staircase structure is comparatively simple and crude, does not distinguish stair middle parts stressed, different structures different from bottom and complete specific design.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing in prior art, a kind of antidetonation stair are provided, between these stair and main body, there is enough bufferings, thereby the safety of stair when having guaranteed earthquake, the technical scheme adopting is: a kind of beam type antidetonation stair, comprise intermediate layer staircase and bottom staircase, it is characterized in that: described intermediate layer staircase comprises the intermediate floor beam I setting gradually from top to bottom, middle stair stringer II and intermediate floor beam III, between described intermediate floor beam III and middle stair stringer II, be provided with gap, in intermediate floor beam III, be also provided with bridging piece, described intermediate layer staircase also comprises intermediate floor plate.
Technical characterictic of the present utility model also has: described bottom staircase comprises bottom floor beam I, bottom stair stringer II and the base layer support device setting gradually from top to bottom, and described base layer support device comprises sliding support.
Technical characterictic of the present utility model also has: described base support means comprises bottom floor beam I and bottom floor beam II, between bottom floor beam I and bottom floor beam II, is floor slab.
Technical characterictic of the present utility model also has: described bridging piece comprises steel bar stress prefabricated in concrete and concrete, and described steel bar stress one end is inserted in described intermediate floor beam III.
Technical characterictic of the present utility model also has: in described gap, be filled with polyphenyl plate.
The beneficial effects of the utility model are: the utility model is for the intermediate layer of building and the difference of bottom stressing conditions, the stair that are applied to different parts, there is good anti seismic efficiency have been designed, once there is earthquake, by means of sliding support and specially designed bridging piece and floor slab, reach antidetonation object.The utlity model has the advantage that anti seismic efficiency is good, enforcement is convenient, with low cost.
Accompanying drawing explanation
Accompanying drawing 1 is intermediate layer staircase structural representation, and accompanying drawing 2 is bottom stair part-structure schematic diagrames, and accompanying drawing 3 is bridging piece structural representations, wherein 1 is intermediate floor beam I, the 2nd, and middle stair stringer II, the 3rd, intermediate floor beam III, the 4th, gap, the 5th, bridging piece, the 6th, intermediate floor plate, the 7th, bottom floor beam I, the 8th, bottom stair stringer II, the 9th, bottom floor beam I, the 10th, bottom floor beam II, the 11st, floor slab, the 12nd, steel bar stress, 13 is sliding support.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.The utility model discloses a kind of beam type antidetonation stair, according to the difference of stair present position, the stair on whole building body can be divided into intermediate layer staircase and bottom staircase.Intermediate layer staircase comprises the intermediate floor beam I 1 setting gradually from top to bottom, middle stair stringer II 2 and intermediate floor beam III 3, between intermediate floor beam III 3 and middle stair stringer II 2, is provided with gap 4, in intermediate floor beam III 3, is also provided with bridging piece 5.Intermediate layer staircase also comprises intermediate floor plate 6.Bottom staircase comprises bottom floor beam I 7, bottom stair stringer II 8 and the base layer support device setting gradually from top to bottom, and this base layer support device comprises sliding support.Base support means comprises bottom floor beam I 9 and bottom floor beam II 10, between bottom floor beam I 9 and bottom floor beam II 10, is floor slab 11.
In gap, be filled with polyphenyl plate.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
