Abstract
The utility model discloses a separated shock-absorption stair which is composed of stair beams, a stair column, stair plates and a stair rest platform, wherein the stair plates and the stair rest platform are fixed in a frame formed by a frame column and frame beams by virtue of the stair beams and the stair column; a horizontal separation layer is arranged between the stair plates and the stair rest platform or between the stair plates and a floorslab; or a horizontal separation layer or a vertical separation gap is arranged between the stair rest platform and the frame structure. In the separated shock-absorption stair, the horizontal separation or slippage layer is adopted, and the vertical separation gap is arranged, so that an inclined support effect on the building structure under the action of the horizontal load, such as earthquake and the like by the stair, can be eliminated; the adverse effect on the anti-shock capacity of the building structure by the stair is avoided; meanwhile, complexity caused by the condition that the building structure design needs stair calculation analysis is avoided; and the problem of building cost addition because the stair needs to participate in the anti-shock design is solved. The separated shock-absorption stair is good in economical efficiency, and the anti-shock capacity of the building structure can be improved.
Description
Technical field
The utility model relates to Structure Design for Folding plate Stairs, the separate type shock-absorbing type stair of particularly a kind of frame construction and Frame _ Shear Wall Structure middle frame part.
Background technology
China is the multiple country of an earthquake, and the whole nation except that minority is economized earthquake more than 6 grades took place all.It is about more than 2/3 that the area in basic earthquake intensity 6 degree and above area accounts for whole areas.China also is one of country that earthquake disaster is the most serious in the world.2008,8.0 grades of Wenchuan violent earthquakes that China takes place just caused huge casualties and economic loss.Earthquake shows, the earthquake main cause with economic loss that causes casualties is the destruction of building construction and collapse.Earthquake reflects that also the anti-seismic technology of more existing building structure or structural element (like stair) is difficult to satisfy the demand for security of people to dwelling environment and good life.
The stair of a large amount of frame constructions and Frame _ Shear Wall Structure middle frame part suffer comparatively serious destruction in the earthquake, and the frame column that links to each other with stair also damages to some extent.Current, do not consider stair participation overall structure co-operation in the conventional design, stair self are not carried out seismic design yet.Yet in fact stair connect together with overall structure, and under geological process, stair become the member with diagonal brace effect, and are all very big to the influence of frame construction overall performance, the agent structure member that links to each other with stair and stair self stress performance.The premiere feature of stair should be evacuation, rescue passage in the building structure in earthquake, rather than at first surrender, becomes first power consumption member in the overall structure, is serving as the first road anti-vibration defense lines.Therefore, conventional design or the stair that do not carry out seismic design can't satisfy shockproof requirements in the past, so can't bring into play its as evacuate, the premiere feature of rescue passage.
Therefore, stair are carried out seismic design and as if become the inevitable means that improve frame construction anti-seismic performance and stair self shock resistance.In research process to the anti-seismic performance of stair; Engineers and technicians have proposed some and have strengthened the seismic measures and the method for structure or member shock resistance; As stair self are carried out seismic design; Strengthen the frame column of staircase or change newel into frame column, and staircase is designed to steel concrete or brick shear wall structure or the like.But study comparison through the applicant; Though above-mentioned Seismic Design Method and measure can strengthen the shock resistance and the earthquake disaster mitigation of stair to a certain extent; But can not fundamentally change in the building structure stair to the adverse effect of agent structure; Can not change its structural deterioration pattern, so still do not satisfy the requirement of antidetonation.Therefore be necessary frame construction and Frame _ Shear Wall Structure middle frame staircase design are partly innovated or improved from thinking.
