Abstract
The invention discloses a reinforced concrete stair sliding support. A sub-structure independent from the main body structure is adopted, the sliding support is connected with the gangboard of the main body structure, the sliding support is arranged beneath the starting position of each layer of stair to limit the vertical displacement and release the horizontal displacement; the sliding support is made from embedded steel plates, and graphite powder is arranged between the steel plates. The reinforced concrete stair sliding support disclosed by the invention can be independent from the main body structure to reduce the unbeneficial effects of the main body structure on the stair, and the sliding stair is arranged to release the earthquake force, so as to reduce the damage of the earthquake force to the tunnel escape of the stair.
Description
Technical field
The present invention relates to steel concrete slip stair design of node and building technology field.
Background technology
At present, stair, as fire escape, serve as very important function in whole building, but in seismic damage empirical discovery in the past: stair earthquake is comparatively serious, and had a strong impact on the evacuation of floor crowd, passway for escaping has become dead passage.Thus, stair should have good anti-seismic performance, the function of safety island, life passage can be played when earthquake, therefore stair minor structure system is set, independent of agent structure, agent structure can be reduced to the adverse effect of stair, slip stair is set, can seismic forces be discharged, reduce seismic forces to the destruction of stair passway for escaping.
Summary of the invention
In order to overcome the defect of prior art, reducing reinforced concrete stairs to the impact of the seismic forces of frame construction, the invention provides a kind of stair minor structure system band reinforced concrete stairs sliding support.
For solving the problems of the technologies described above, the invention provides a kind of reinforced concrete stairs sliding support, it is characterized in that, adopt the minor structure independent of agent structure, sliding support is adopted to be connected with the gangboard of agent structure, sliding support is arranged on below the original position of every floor ladder, restriction vertical displacement, emission levels displacement; Sliding support adopts pre-embedded steel slab, arranges graphite powder between steel plate.
Sliding support comprises the top steel plate being positioned at top and the end steel plate being positioned at below, arranges graphite powder between top steel plate and end steel plate.
The width of sliding support is identical with each tread run in stair step.
The length of sliding support is identical with gangboard width.
Top steel plate length is identical with gangboard width, and end steel plate length is greater than the length of top steel plate, and the both sides of end steel plate upwards bend, formation lateral Displacement plate, make top steel plate lateral Displacement plate spacing lower hold by the end steel plate.
Sliding support place arranges the stopping means of limit lateral displacement.
The present invention compared with prior art, has the following advantages:
(1) stair sliding support is set, can seismic forces be discharged, reduce seismic forces to the destruction of stair, reduce stair self earthquake;
(2) stair gangboard is reduced as the impact of diagonal supporting member on agent structure;
(3) easy construction, is easy to operation;
(4) minor structure (independent of agent structure) taked by stair, and minor structure system is stressed clear, and power transmission is clear and definite.

Detailed description of the invention
As shown in Figure 1, reinforced concrete stairs of the present invention adopts the minor structure 100 independent of agent structure, is connected gangboard with agent structure, adopts the form of sliding support.Sliding support 1 is arranged on stair original position, and sliding support 2 arranges stair minor structure place, and sliding support 3 is all next level ladder rung TB starting point.Between stair half storey landing slab PTB1 and agent structure, aseismatic joint 4 is set; After aseismatic joint 4 is set, the adverse effect of short column, ultrashort post will not existed to main structural frame post 5.Sliding support is taked to limit vertical displacement, the form of emission levels displacement.The two ends of every floor ladder half storey landing slab PTB1 are all supported by short column TZ1 by beam TL1, TL2.Three floor ladder gangboard TB-1, TB-a, TB-b are only shown in the present embodiment.
Shown in composition graphs 2-Fig. 7, the width of sliding support 2 is identical with each tread run TB-y in stair gangboard TB-1.
Roughly wide TB-x is close with gangboard for the length of sliding support 2.Sliding support 2 comprises the top steel plate 21 being positioned at top and the end steel plate 22 being positioned at below, between top steel plate 21 and end steel plate 22, graphite powder is set, wherein, top steel plate 21 length is identical with the wide TB-x of gangboard, end steel plate 22 length is greater than the length of top steel plate 21, and the both sides of end steel plate 22 upwards bend, form lateral Displacement plate 23, make top steel plate 21 lateral Displacement plate 23 spacing lower hold by the end steel plate 22.Sliding support takes pre-embedded steel slab, arranges graphite powder between steel plate, increases the sliding capability between steel plate.Compared with existing slip stair, add minor structure system, sliding support place is provided with the stopping means of limit lateral displacement, reduces the adverse effect that gangboard reverses.
In the present embodiment, end steel plate length is: top steel plate length (the wide TB-x of gangboard)+50mm+100mm+100mm.Wherein, two ends respectively upwards bend 100mm and form lateral Displacement plate, and the length of the accommodation top steel plate that bending is formed afterwards has certain surplus.
Reinforced concrete stairs sliding support work progress:
On-the-spot formwork, assembling reinforcement, cast-in-place layer bench concrete, after this layer of bearing place concrete reaches 50% intensity, upper strata gangboard formwork, assembling reinforcement, builds bench concrete.
