Description

A kind of antidetonation stair
Technical field
The utility model relates to a kind of stair, is specifically related to a kind of antidetonation stair, belongs to construction engineering technical field.
Background technology
In the building of frame construction, because its vertical lateral resisting structure is frame column, therefore relative shear wall structure, the anti-seismic performance of frame construction is more weak.In stair position, because in the middle part of floor, half space beam is connected with frame column, make frame column length herein relatively short, shear span is smaller, more easily brittle fracture occurs under external force; In addition because stair bench serves diagonal bracing effect, under horizontal earthquake action, stair position rigidity is relatively large, thus makes the frame column at stair position assume responsibility for more horizontal earthquake action, further causes the destruction of stair position frame column.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel antidetonation stair, to overcome described defect of the prior art.
Utility model content
For solving the problem, it is simple, easy for installation that the purpose of this utility model is to provide a kind of structure, and power transmission is clear and definite, can bear repeatedly change in displacement and survivable antidetonation stair.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of antidetonation stair, and it comprises precast stair plate, stair stringer, constructional column and Vierendeel girder; Wherein, described precast stair plate is made up of waist slab, the half space plate being positioned at waist slab two ends and the fixed bearing upper component be separately positioned on half space plate and movable support upper component; In the corrosion resistant plate that described fixed bearing upper component is provided with through circular hole and is embedded in advance bottom circular hole; In the corrosion resistant plate that described movable support upper component is provided with through elongate holes and is embedded in advance bottom elongate holes; Described stair stringer is arranged on the bottom of half space plate, and it is held on Vierendeel girder and constructional column respectively; In the shear key that the top of described stair stringer is provided with pre-buried corrosion resistant plate and is embedded in the middle part of pre-buried corrosion resistant plate; Described shear key penetrates described circular hole and elongate holes respectively; In circular hole, between elongate holes and shear key, be filled with elastic rubber material layer respectively.
Antidetonation stair of the present utility model are set to further: be provided with body of wall in described waist slab, half space plate side, leave gap between body of wall and waist slab, half space plate.
Antidetonation stair of the present utility model are set to further: between two half space plates of precast stair plate homonymy, be provided with space.
Antidetonation stair of the present utility model are set to further: described half space plate is separated setting with waist slab, is provided with space between half space plate and waist slab; Be provided with body of wall in described waist slab side, between body of wall and waist slab, leave gap.
Antidetonation stair of the present utility model are also set to: the bottom of described half space plate and waist slab arranges described stair stringer respectively, arranges secondary beam between adjacent stair stringer.
Compared with prior art, the utility model has following beneficial effect:
1. antidetonation staircase structure of the present utility model is simple, convenient installation.
2. antidetonation stair of the present utility model are under horizontal earthquake action, precast stair plate can move horizontally on stair stringer, significantly reduce stair tread to the diagonal bracing effect of building structure, stair stringer is shelved on constructional column simultaneously, and constructional column and frame column maintain certain distance, so make under horizontal earthquake action, stair tread can be ignored substantially to the negative effect of agent structure.
3. antidetonation stair of the present utility model, are provided with shear key in bearing, and shear key has certain height, can effectively prevent stair tread under geological process repeatedly, departing from stair stringer.
4. antidetonation stair of the present utility model, filling elastomeric material in the upper component hole of bearing, can avoid under normal use, stair tread has larger movement, and alleviates under geological process, and shear key is to the stress concentration effect of the shearing force of half space plate.
5. antidetonation stair of the present utility model, stay seam with periphery body of wall, reserve larger space, the destruction to periphery body of wall when can effectively avoid stair tread to move what have a movable support side between half space plate its end and body of wall.

Detailed description of the invention
Refer to shown in Figure of description 1, accompanying drawing 2 and accompanying drawing 5, it is the first embodiment of a kind of antidetonation stair of the present utility model, and it is made up of a few parts such as precast stair plate 1, stair stringer 2, constructional column 3 and Vierendeel girders 4.
Wherein, described precast stair plate 1 is made up of waist slab 12, the half space plate 11 being positioned at waist slab 12 two ends and the fixed bearing upper component 13 be separately positioned on half space plate 11 and movable support upper component 14.In the corrosion resistant plate 132 that described fixed bearing upper component 13 is provided with through circular hole 131 and is embedded in advance bottom circular hole 131.In the corrosion resistant plate 142 that described movable support upper component 14 is provided with through elongate holes 141 and is embedded in advance bottom elongate holes 141.
Described stair stringer 2 is arranged on the bottom of half space plate 11, and it is held on Vierendeel girder 4 and constructional column 3 respectively.In the shear key 222 that the top of described stair stringer 2 is provided with pre-buried corrosion resistant plate 221 and is embedded in the middle part of pre-buried corrosion resistant plate 221.Described shear key 222 penetrates described circular hole 131 and elongate holes 141 respectively, because shear key 222 has certain height, can effectively prevent precast stair plate 1 under geological process repeatedly, departing from stair stringer 2.In circular hole 131, between elongate holes 141 and shear key 222, be filled with elastic rubber material layer 5 respectively.
