Abstract
The utility model provides a stair sliding support, belongs to concrete structure technical field. Including end steel sheet (1), top steel sheet (2), end steel sheet (1) is located the below, and top steel sheet (2) are located the top, filled stone powdered ink between end steel sheet (1) and top steel sheet (2), establish on end steel sheet (1) and top steel sheet (2) reinforcing bar fluke (3), upwards buckling in the both sides of end steel sheet (1), forms the side direction limiting plate, makes top steel sheet (2) held by end steel sheet (1) under side direction limiting plate spacing. Steel sheet (1), top steel sheet (2) go up by long 120mm's 6 reinforcing bars of diameter respectively welded connection put pre -buried among marking time, even spilling the graphite powder on steel sheet when pre -buried. The utility model discloses the advantage lies in that the sliding support adopts pre -buried steel sheet, sets up the graphite powder between the steel sheet, can be independent of the major structure, and the reduction major structure sets up the slip stair to the adverse effect of stair, can release earthquake power, reduces the destruction of earthquake power to the stair passway for escaping.
Description
Technical field
The utility model belongs to concrete structure technique field, particularly provides a kind of stair to slideBearing, is applicable to architectural engineering.
Background technology
At present, stair, as fire escape, serve as very important function in whole building,But the eaerthquake damage empirical discovery in the past: stair earthquake is comparatively serious, has had a strong impact on floor crowdEvacuation, passway for escaping has become dead passage. Thereby stair should have good anti-seismic performance,Can in the time of earthquake, bring into play the function of safety island, life passage, thus stair minor structure system is set,Can be independent of agent structure, reduce the adverse effect of agent structure to stair, slip stair are set,Can discharge seismic force, reduce the destruction of seismic force to stair passway for escaping.
The cast-in-situ steel reinforced concrete stair of conventional construction mode in the time of earthquake owing to joining as inclined memberAdd lateral resisting work, not only make agent structure rigidity strengthen, cause the Stiffness Distribution in floor levelInhomogeneous, structural entity analysis result is produced a very large impact, and often make stair become firstRoad anti-vibration defense lines and early destroying, is difficult to ensure the realization of its evacuating personnel and rescue function, specialLarger on frame structure impact.
Prior art sliding support adopts the thick polyfluortetraethylene plate 4 of 5mm, fixing with flat head screw 5,Operate extremely inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of stair sliding support, adopts and is independent of body junctionThe minor structure of structure, adopts sliding support to be connected with the gangboard of agent structure, and sliding support is arranged on oftenThe original position below of floor ladder, restriction vertical displacement, emission levels displacement; Sliding support adoptsPre-buried end steel plate 1 and top steel plate 2, establish reinforcing bar anchor fluke 3 on end steel plate 1 and top steel plate 2, end steel plate1 and top steel plate 2 between graphite powder is set.
The utility model comprises end steel plate 1, top steel plate 2; End steel plate 1 is positioned at below, top steel plate 2Be positioned at top. Filled stone ink powder between end steel plate 1 and top steel plate 2. End steel plate 1 and top steel plate 2On establish reinforcing bar anchor fluke 3.
Steel plate 2 length in top are identical with gangboard width, and steel plate 1 length in the end is greater than the length of top steel plate 2,And the both sides of end steel plate 1 upwards bend, form lateral Displacement plate, limit lateral displacement. Make topSteel plate 2 is held by end steel plate 1 at the spacing lower of lateral Displacement plate, on each steel plate by lengthAmong Ф 6 reinforcing bars of 120mm are welded to connect respectively and are a little embedded in and mark time. When pre-buried uniformly by graphitePowder is sprinkling upon on steel plate.
The width of sliding support is identical with the each tread run in stair step.
The length of sliding support is identical with gangboard width.
The utility model has the advantage of
(1) stair sliding support is set, can discharges seismic force, reduce the destruction of seismic force to stair,Reduce stair self earthquake;
(2) reduce the impact on agent structure as diagonal supporting member of stair gangboard;
(3) steel plate 1 and steel plate 2 substitute polyfluortetraethylene plate 4, and Ф 6 reinforcing bars 3 substitute flat head screw5, easy construction, easy operating;
(4) stair are taked minor structure (being independent of agent structure), and minor structure system is stressed clear, power transmissionClearly.
Beneficial effect of the present invention
Sliding support adopts local support, with the structure phase that adopts the full contact-making surface supporting in waist slab lower endRatio, not only saves material, reduces cost, and due to the reducing of contact friction face, has reduced and rubbedWipe resistance, be conducive to improve sliding effect;
Adopt the upper and lower pre-embedded steel slab of bearing and completely spread graphite powder to form carriage, with polytetrafluoroethyl-neAlkene backing plate is compared, and greatly reduces cost, becomes economical sliding support;
Between the upper surface of the lower surface of waist slab lower end and lower end supporting member, arranging localPosition, all spaces beyond bearing unit, when adopting the practice of filled polystyrene cystosepiment, not onlyCan this separate between waist slab and lower end supporting member concrete surface contact, while reducing to slideFrictional resistance, and can utilize its bottom template as this place, constructability.

In figure, end steel plate 1, top steel plate 2, the long Ф 6200 reinforcing bar anchor flukes 3 of 120mm, 5mm are thick poly-Tetrafluoroethene plate 4, flat head screw M45, be connected with concrete, spacing is not more than 200;
Detailed description of the invention
The utility model comprises end steel plate 1, top steel plate 2; End steel plate 1 is positioned at below, top steel plate 2Be positioned at top. Filled stone ink powder between end steel plate 1 and top steel plate 2. End steel plate 1 and top steel plate 2On establish reinforcing bar anchor fluke 3.
As shown in the figure, be connected gangboard with agent structure, adopt the form of sliding support. Sliding supportStair minor structure place and next level ladder rung starting point are set. Stair half storey landing slab and body junctionAseismatic joint is set between structure; Aseismatic joint is set and will have short column, ultrashort post to main structural frame postAdverse effect. Sliding support takes to limit vertical displacement, the form of emission levels displacement.
The width of sliding support is identical with each tread run of stair gangboard.
The length of sliding support is roughly wide close with gangboard. Sliding support comprises the top steel that is positioned at topPlate and the end steel plate that is positioned at below, arrange graphite powder between top steel plate and end steel plate, wherein, and top steelPlate length is wide identical with gangboard, and end steel plate length is greater than the length of top steel plate, and end steel plate twoIn side direction, bend, form lateral Displacement plate, make spacing lower to end steel at lateral Displacement plate of top steel platePlate holds. Sliding support is taked pre-embedded steel slab, and graphite powder is set between steel plate, increases between steel plateSliding capability.
