Abstract
The utility model discloses an anti -seismic staircase has solved when the earthquake takes place ladder body concrete and has taken place crack and cracked problem easily. Including this floor ladder (6), upper strata floor (1) and lower floor's floor (8), be provided with lower floor's floor outrigger bracket (10) on the medial surface of lower floor's floor (8), the activity is provided with polytetrafluoroethylene isolation bottom suspension fagging (11) on the upper surface of lower floor's floor outrigger bracket (10), stair upper ends (5) and upper floor (1) of this floor ladder (6) pour to link together, stair lower extreme (7) of this floor ladder (6) are that the activity sets up on polytetrafluoroethylene keeps apart bottom suspension fagging (11). The utility model discloses the earthquake can effectively delay the time that stair take place destruction when taking place, alleviates the degree that stair destroyed to for personnel's the creation condition of fleing for one's life and win the quality time. (U /)
Description
Technical field
A kind of stair of the utility model, particularly a kind of antidetonation stair being not easy to rupture when earthquake occurs.
Background technology
It is overall structure that ordinary reinforced concrete builds stair, the upper end of the gangboard reinforcing bar of these stair and the mutual anchor of upper strata ladder beam steel, the lower end of gangboard reinforcing bar and the mutual anchor of lower floor's ladder beam steel, composition overall structure, when an earthquake occurs, this steel concrete overall structure easily causes stair ladder body concrete to produce slight crack, fracture, causes stair concrete structure to destroy, causes stair to lose escaping function.
Summary of the invention
The utility model provides a kind of antidetonation stair, solves terraced body concrete when an earthquake occurs and the problem of slight crack and fracture easily occurs.
The utility model solves above technical problem by the following technical programs:
A kind of antidetonation stair, comprise this floor ladder, upper strata floor and lower floor's floor, the medial surface of lower floor's floor is provided with lower floor's floor outrigger bracket, the upper surface of lower floor's floor outrigger bracket is movably set with polytetrafluoroethylene (PTFE) isolation lower supporting plate, the stair upper end of this floor ladder and upper strata floor are built and are linked together, and the stair lower end of this floor ladder is movably arranged on polytetrafluoroethylene (PTFE) isolation lower supporting plate.
The medial surface of upper strata floor is provided with upper strata floor outrigger bracket, upper strata floor outrigger bracket is movably set with polytetrafluoroethylene (PTFE) isolation upper backup pad, the lower end of upper strata stair is movably arranged on polytetrafluoroethylene (PTFE) isolation upper backup pad, and the upper end of lower floor's stair and lower floor's floor are built and linked together.
The utility model not only avoids the impact of staircase component on agent structure rigidity, has saved cost, and has irreplaceable superiority relative to common beam and slab type stairway.Effectively can delay the time that stair occur to destroy when earthquake occurs, alleviate the degree that stair destroy, thus create conditions and win the quality time for the escape of personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of antidetonation stair, comprise this floor ladder 6, upper strata floor 1 and lower floor's floor 8, the medial surface of lower floor's floor 8 is provided with lower floor's floor outrigger bracket 10, the upper surface of lower floor's floor outrigger bracket 10 is movably set with polytetrafluoroethylene (PTFE) isolation lower supporting plate 11, stair upper end 5 and the upper strata floor 1 of this floor ladder 6 are built and are linked together, and the stair lower end 7 of this floor ladder 6 is movably arranged on polytetrafluoroethylene (PTFE) isolation lower supporting plate 11.
The medial surface of upper strata floor 1 is provided with upper strata floor outrigger bracket 3, upper strata floor outrigger bracket 3 is movably set with polytetrafluoroethylene (PTFE) isolation upper backup pad 2, the lower end of upper strata stair 4 is movably arranged on polytetrafluoroethylene (PTFE) isolation upper backup pad, and the upper end of lower floor's stair 9 and lower floor's floor 8 are built and linked together.
To go downstairs the design concept that bench bearing end is free to slide in geological process for meeting sliding support, if half space place finishing way is still constructed according to common stair, under geological process, finishing material local damage will inevitably be caused.Therefore, when fitting up layout design, horizontal joint way need be considered.When fitting up Deepen Design and typesetting, can consider that finishing material disconnects at horizontal joint place, and filling with flexible material.
