Description
Technical field
The utility model belongs to the building structure technology field, relates to a kind of stair earthquake isolating equipment.
Background technology
Traditional construction design method is not considered the stressed influence to integrality performance of the structure of stair, does not consider the geological process effect of stair yet.The Wenchuan earthquake earthquake shows that the staircase of building destroys seriously under the big shake effect, comprises bench plate and landing beam generation heavy damage.Therefore, " seismic design provision in building code " GB 50011-2001 (version in 2008) 3.6.6 bar is clearly stipulated: " should consider the influence of staircase component in the calculating ".
On the one hand, staircase component participation structure overall calculation can cause staircase and peripheral structure member force path complexity, is unfavorable for the overall structure antidetonation; In addition, after the consideration staircase was contributed integrally-built rigidity, structure may become " irregular ", and this need take the more structural remedial measure, may have influence on the layout of whole building and structural system.On the other hand, consider " safety island " effect, staircase must be strengthened during seismic design, this means that corresponding staircase component cross section should strengthen, thereby the whole lateral rigidity of staircase is increased, will certainly further increase its geological process and increase the staircase lateral rigidity.The problems referred to above are a pair of contradiction, still do not have good solution at present.
Summary of the invention
The purpose of this utility model provides a kind of stair earthquake isolating equipment, and " the scissors diagonal brace effect " of stair swash plate under geological process discharged, and reduces the geological process effect of staircase component significantly, and the reduction staircase component is to analysis of Integral Structure result's influence.
The technical scheme that the utility model adopted is, a kind of stair earthquake isolating equipment, be included between the stair swash plate of stair stringer and top the shock insulation pad is set, anti-drop device the inboard of stair stringer is provided with outside simultaneously, the stair swash plate soffit above the anti-drop device is provided with interior anti-drop device outside.
Stair earthquake isolating equipment of the present utility model, its feature also is: described shock insulation pad above and below evenly is provided with a plurality of anchor points respectively, and each anchor point is equipped with an anchor bolt, and anchor bolt is fixedlyed connected respectively with stair stringer with the stair swash plate.
Described shock insulation pad be shaped as cuboid, cube, cylinder or their assembly, shock insulation pad and stair stringer be arranged in parallel.
The beneficial effects of the utility model are that stair swash plate seismic Calculation factor can not be considered in designing program of the engineering that simplifies the structure; Staircase structure and staircase safety have been guaranteed; Reduce owing to taking the various construction costs that structural measure increases of remedying, have good practical value and economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model device;
Fig. 2 is the shock insulation pad vertical view in the utility model device;
Fig. 3 is the shock insulation pad schematic cross-section in the utility model device.
Among the figure, 1. shock insulation pad, 2. outer anti-drop device, 3. stair stringer, 4. anchor point, 5. anchor bolt, 6. stair swash plate, 7. in anti-drop device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, stair earthquake isolating equipment structure of the present utility model is, be included between the stair swash plate 6 of stair stringer 3 and top and be provided with shock insulation pad 1, while anti-drop device 2 outside the inboard of stair stringer 3 is provided with, anti-drop device 7 in stair swash plate 6 soffits of anti-drop device 2 tops are provided with outside, outer anti-drop device 2 is structure as a whole with the place basic part respectively with interior anti-drop device 7, or be mounted on the basic part of place by connecting bolt, and outer anti-drop device 2 and interior anti-drop device 7 relative set that staggers, stair stringer 3 is excessive with 6 dislocation of stair swash plate when being used to prevent earthquake, influences the stair overall structure.
With reference to Fig. 2, Fig. 3, shock insulation pad 1 adopts three-dimensional shapes such as cuboid, cube or cylinder, be arranged in parallel with stair stringer 3, be positioned between the lower end and stair stringer 3 of every section stair swash plate 6, shock insulation pad 1 above and below evenly is provided with anchor point 4 respectively, each anchor point 4 is equipped with an anchor bolt 5, and shock insulation pad 1 is fixedlyed connected with stair stringer 3 with stair swash plate 6 by the anchor bolt 5 that is installed in the anchor point 4, so that be connected as a whole with the shock insulation pad stair stringer, stair swash plate; And the upper end of every section stair swash plate 6 is fixed on the stair stringer of last layer still according to traditional design method, guarantees stair stablizing under normal operating condition.In order to guarantee the safety of big shake effect between going downstairs, prevent earthquake isolating equipment generation large deformation, the combined type anti-drop device is set between stair swash plate and stair stringer.
Big, the anti-side rigidity of the material requirements vertical rigidity of shock insulation pad 1 is little, have bigger horizontal distortion ability, as lamination isolation rubber pad on the market etc.The vertical load of stair swash plate in the time of can bearing normal the use on the one hand, the operate as normal of assurance stair.On the other hand, under horizontal earthquake action, the oblique buttressing effect of stair swash plate can make shock insulation pad generation level to distortion, can earthquake energy.Because the stair swash plate can slide relatively with stair stringer, its " scissors diagonal brace effect " can significantly reduce.
Stair earthquake isolating equipment of the present utility model was placed on the shock insulation pad between the steel mesh reinforcement of stair stringer and stair swash plate in when construction, and the anchor bolt of shock insulation pad and the steel mesh reinforcement of terraced beam and gangboard are welded, and carried out integrated poured then.
