Abstract
The utility model discloses a beam-type staircase with an anti-seismic device. The beam-type staircase with the anti-seismic device comprises a staircase beam and a platform support. The staircase beam is arranged above the platform support. A preset gap is arranged between the staircase and the platform support. The beam-type staircase with the anti-seismic device additionally comprises two steel plates. One steel plate is fixedly connected with the bottom surface of the staircase beam. The other steel plate is fixedly connected with the top surface of the platform support. A sliding layer is arranged between the two steel plates. The beam-type staircase with the anti-seismic device has the advantages of very good seismic performance, high feasibility and low construction cost.
Description
Technical field
The utility model relates to a kind of stringertype stairway with antishock device.
Background technology
At present, stair generally adopt the scheme of stair stringer and landing beam monobloc cast, and the drawback of this scheme maximum is when earthquake, and the diagonal brace system of stair has absorbed very large seismic forces, easily cause the breaking-up of stair or collapse.The destruction that characteristics are staircase components of the damaged building of Wenchuan violent earthquake has affected passway for escaping safety, causes huge property loss and casualties to the country and people.According to (GB50011-2001) 3.6.6 bar of versions " seismic design provision in building code " in 2008, should consider the impact of staircase component in the structural calculation, and national standard drawings " 11G101-2 " only provides the node of slabtype stairway, and the stringertype stairway anti-seismic problem is not yet related to.For the commercial public place of a large amount of personnel's highly denses, because often imperative selection of stringertype stairway is adopted in the requirement of function, in case breaking-up or loss and the social influence that produces of collapsing are well imagined.Because the limitation of existing software, compare analyzing is comparatively coarse, if having metaprogram to calculate with general, input and the mesh generation of swash plate, terraced beam and cleat stanchion bother, calculate very loaded down with trivial detailsly, thereby the cost of structure and construction analysis calculated bring a lot of adverse influences.
The utility model content
The technical problems to be solved in the utility model provides a kind of stringertype stairway with antishock device, and anti-seismic performance is fine, and exploitativeness is strong, and is cheap.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of stringertype stairway with antishock device comprises stair stringer, stage support, and described stair stringer is arranged at the top of stage support, leaves predetermined gap between described stair stringer and the stage support,
Described stringertype stairway with antishock device also comprises antishock device, described antishock device comprises two block plates, a described wherein block plate is fixedly connected on the bottom surface of stair stringer, and described another block plate is fixedly connected on the end face of stage support, is provided with sliding layer between described two block plates.
As improvement, antishock device described in the utility model also comprises two limited blocks, and described two limited blocks are fixedly connected on the end face of stage support and lay respectively at the both sides of stair stringer bottom.
Preferably, sliding layer described in the utility model is made by pitch or graphite.
Therefore compared with prior art, the utility model has following beneficial effect:
During earthquake, stair stringer can slide with respect to stage support by the steel plate in the antishock device, and the energy that earthquake produces can not absorbed by stair stringer, thereby has avoided the damage of stair, make stair can really become " umbrella " of protecting evacuating personnel, particularly important to crowded place; In addition, the utility model difficulty of construction is less, and exploitativeness is very strong, and cost is cheaper, and Calculation Anaysis for Tunnel Structure is simple, so the scope of application is wider.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Be illustrated in figure 1 as the embodiment of a kind of stringertype stairway with antishock device described in the utility model, comprise stair stringer 1, stage support 2, stair stringer 1 is arranged at the top of stage support 2, leave predetermined gap between stair stringer 1 and the stage support 2, the present embodiment also comprises antishock device, and antishock device comprises two block plates 3, and wherein a block plate 3 is fixedly connected on the bottom surface of stair stringer 1, another block plate 3 is fixedly connected on the end face of stage support 2, is provided with sliding layer 4 between two block plates 3.Wherein, the gap between stair stringer 1 and the stage support 2 can be adjusted according to earthquake displacement.
As improvement, in the present embodiment, antishock device comprises that also 5, two limited blocks 5 of two limited blocks are fixedly connected on the end face of stage support 2 and lay respectively at the both sides of stair stringer 1 bottom, can prevent stair stringer 1 landing when earthquake like this.
Preferably, in the present embodiment, sliding layer 4 is made by pitch or graphite.During construction, stair stringer 1 and stage support 2 be pre-embedded steel slab 3, the then less materials of friction factor such as pitching or graphite between two block plates 3 respectively.
The above technical scheme that the utility model embodiment is provided is described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
