Description
Technical field
The utility model belongs to building field, and in particular to a kind of novel cast-in-situ steel reinforced concrete stair.
Background technology
In the building by eaerthquake damage, the frequent well damage of stair, preferred escape route when as earthquake,
In seismic design of structures, certain construction measure is preferably taken, reduces influence of the staircase component to agent structure rigidity.For cast-in-place
Reinforced Concrete Plate Stairs can replace original hold-down support in stair lower end sliding support, reach this detailing requiments.
In coming earthquake, sliding support can slide back and forth in a certain range, and the effective stair that reduce destroy, and are won for personnel escape
Time.There are two types of the ways of general sliding support, and one is being arranged at terraced back end, another setting chooses ear on terraced beam
Place, but when having clear height or ladder length limits, both ways are simultaneously not suitable for.
Utility model content
Technical problem to be solved in the utility model is：A kind of novel cast-in-situ steel reinforced concrete stair are provided, can be subtracted
Few influence of the staircase component to agent structure rigidity, and the limitation of stair clear height can be met.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution：
A kind of novel cast-in-situ steel reinforced concrete stair, including cleat stanchion, cleat stanchion are vertically arranged in bench inclined plate right, on cleat stanchion
End is provided with terraced beam, and terraced beam includes horizontal segment and vertical section, and vertical section setting exists in horizontal segment left end and the setting of vertical section lower end
On cleat stanchion, what vertical section left end middle and lower part was horizontally disposed with the cast of useful concrete chooses ear, chooses and is provided with pedal, horizontal segment above ear
Upper surface is concordant with pedal upper surface, and the first gap is provided between vertical section top and pedal, is filled in the first gap poly-
Benzene plate, pedal and chooses and is provided with the second gap between ear, polyfluortetraethylene plate is filled in the second gap, pedal left end is provided with
The bench inclined plate tilted upward.
First clearance gap is 40-60mm.
Polyphenyl plate thickness is 5mm.
It chooses ear width and is not less than tread width, choose ear thickness and be not less than pedal thickness.
Polyfluortetraethylene plate, width, which is equal to, chooses ear width, and length is equal to tread length.
Pedal is an integral structure with bench inclined plate.
Compared with the existing technology, the beneficial effects of the utility model are：The utility model is by between pedal and terraced beam
Styrofoam and polyfluortetraethylene plate is respectively set, limited displacement is provided for stair, improves the stability of stair, this practicality is new
Type can make stair size meet code requirement in the space for having clear height limitation or length limitation, when coming earthquake, bench
Plate can carry out finite displacement, ensure staircase component safety, used for personnel escape.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, ear 2, cleat stanchion 3, terraced beam 4, styrofoam 5, pedal 6, bench inclined plate 7, polyfluortetraethylene plate are chosen.
Specific implementation mode
Embodiment：As shown in Figure 1, a kind of novel cast-in-situ steel reinforced concrete stair, including cleat stanchion 2, cleat stanchion 2 are vertically arranged in
6 right of bench inclined plate, 2 upper end of cleat stanchion are provided with terraced beam 3, and terraced beam 3 includes horizontal segment and vertical section, and vertical section is arranged in horizontal segment
Left end and vertical section lower end are arranged on cleat stanchion 2, and what vertical section left end middle and lower part was horizontally disposed with useful concrete cast chooses ear 1,
It chooses 1 top of ear and is provided with pedal 5, horizontal segment upper surface is concordant with 5 upper surface of pedal, is arranged between vertical section top and pedal 5
There is the first gap, is filled with the styrofoam 4 of multiple non-uniform thickness, the first clearance gap is 40-60mm, in the present embodiment, first
Clearance gap is 50mm, pedal 5 and chooses and is provided with the second gap between ear 1, and polyfluortetraethylene plate 7 is filled in the second gap,
In the present embodiment, 4 thickness of styrofoam is 5mm, and 5 left end of pedal is provided with the bench inclined plate 6 tilted upward, it is not small to choose 1 width of ear
In 5 width of pedal, chooses 1 thickness of ear and be not less than 5 thickness of pedal, polyfluortetraethylene plate 7, width, which is equal to, chooses 1 width of ear, length etc.
It is same as 5 length of pedal, pedal 5 is an integral structure with bench inclined plate 6.
When implementing, bench inclined plate 6 and pedal 5 are an integral structure the utility model, and 5 right end of pedal and terraced beam 3 are horizontal
The styrofoam 4 filled between section, the polyfluortetraethylene plate 7 filled between 5 lower end of pedal and ladder 3 vertical section of beam, can be bench
Inclined plate 6 provides limited displacement, ensures staircase component safety.And fill styrofoam between 3 horizontal segment of 5 right end of pedal and terraced beam
After 4,4 height of styrofoam and building coats are contour, stair size can be kept full in the space for having clear height limitation or length limitation
Sufficient code requirement.
