Description
Technical field
The utility model relates to a kind of prefabricated component stair of light silencing, belong to building engineering field.
Background technique
Stair are divided into cast-in-situ steel reinforced concrete stair and two kinds of precast stair.Cast-in-situ steel reinforced concrete stair are whether board-like
Stair or stringer type stairway are required to a large amount of live formworks when constructing, after assembling reinforcement after-pouring concrete conserves 14~21 days again
Demoulding molding, construction is complicated, long in time limit, and cost is high.Precast stair pours in factory's formwork in advance according to size, after maintenance is good
It is transported to construction site, need to only complete lifting splicing at the scene, easy construction, short time limit, cost is lower than cast-in-place, but mesh
Preceding precast stair weight is big, calculates according to the most commonly used ST-30-25 model precast stair in national standard, and single flight weight is up to 2.1
~2.4 tons, be more than the tolerance zone of 1.5 tons of small-sized tower crane, it is necessary to use large-scale tower crane equipment, bring to transporting with lifting
It is inconvenient.And current stair whether it is cast-in-place or it is prefabricated be all using armored concrete, cause people walk stair when unavoidably
Noise can be generated, while precast stair generally uses fixed-hinged support to connect in bench with cast-in-situ stair at platform, causes just
It spends bigger than normal, is unfavorable for antidetonation.
Utility model content
The utility model is that the existing cast-in-situ stair construction of solution is complicated, long in time limit, cost is high, and precast stair weight is big, transports
The technical issues of defeated lifting inconvenience, poor seismic behavior, walking generate noise, its purpose is to provide a kind of quick constructions, duration

The plugging wire insulation board of concrete topping is wrapped up in plate for surrounding, placed concrete topping steel wire in surrounding package concrete topping
Net, at the bearing of waist slab upper end with there are two fixed hinge pin key hole to be provided and sliding hinge pin key are pre- respectively at the bearing of waist slab lower end
Box out, wherein at the bearing of waist slab upper end be fixed hinge pin key hole to be provided and it is internal place reinforcing bar at the bearing of waist slab upper end,
It is reinforcing bar at sliding hinge pin key hole to be provided and internal placement waist slab lower end bearing at the bearing of waist slab lower end.
Further, tread plate is on every layer mark time, and mark time it is interior reserved lifting built-in fitting, each mark time down
Plugging wire insulation board be all provided with there are two plugging wire insulation board reserve grout hole.
Further, it is 40~60mm that plugging wire insulation board, which reserves the diameter of grout hole,.
Further, surrounding package concrete topping plugging wire insulation board with a thickness of 40~50mm.
Further, the material of insulation board is material containing polystyrene thermal insulation plate in plugging wire insulation board.
A kind of preparation method of the prefabricated component stair of light silencing, this method include the following:
A, the oblique beam steel bar colligation in downside is put into the mold of precast stair well first；
B, the plugging wire insulation board for including plugging wire insulation board concrete grouting hole is fixed, and surrounding places the coagulation bound
Native surface layer steel fabric sheet；
C, by reinforcing bar binding and fixing at the bearing of waist slab upper end at the bearing of waist slab upper end, at the bearing of waist slab lower end steel
Muscle binding and fixing are at the bearing of waist slab lower end；
D, close casting concrete, wait conserve after demoulding, transport is to construction site；
E, stair temporary support, fixed upper and lower ends landing are set;
F, hoisting prefabricated component stair make to be individually positioned at the bearing of waist slab upper end, at the bearing of waist slab lower end up and down
On the landing of both ends, and it is directed at the fixation hinge pin key hole to be provided at the bearing of waist slab upper end and the cunning at the bearing of waist slab lower end
Dynamic hinge pin key hole to be provided；
G, it installs at the upper end bearing of stair waist slab: the bolt being embedded in platform board is inserted at the bearing of waist slab upper end
Fixation hinge pin key hole to be provided in；
H, it installs at the lower end bearing of stair waist slab: the bolt being embedded in platform board is inserted at the bearing of waist slab lower end

Working principle is as follows:
Plugging wire insulation board is put into stair waist slab, instead of the weight of stair a big chunk concrete, and in ladder
Section plate surrounding reserves the concrete topping of 40~50mm thickness, and concrete topping steel wire is put into it, fixed when prefabricated to insert
Casting concrete, concrete can be filled from plugging wire insulation board is reserved in mold after silk insulation board and concrete topping steel wire position
Slurry flows into hole, so that concrete topping and internal plugging wire insulation board become an entirety, then the two sides below waist slab up and down
It is respectively arranged a cant beam, using stair stringer sandwich heat preservation technology, allows the stair for mitigating weight that can still bear normal use pole
Limit state load, specific reinforcing bar arrangement of reinforcement are calculated according to the practical specification of stair.At the bearing of waist slab upper end with waist slab lower end branch
Hold place and be provided with fixed hinge pin key hole to be provided and sliding hinge pin key hole to be provided, at the bearing of waist slab upper end with upper end platform,
At the bearing of waist slab lower end with the overlap joint of lower end platform.Stair can be produced using lower end sliding hinged-support when coming earthquake
Raw certain free run, discharges destructive power of the earthquake and is unlikely to generate structure destruction.Width at the bearing of bench upper end
A small distance longer than width at waist slab and the bearing of bench lower end, so that at the bearing of bench upper end and at the bearing of bench lower end
After the splicing of upper and lower platform board, meeting self-assembling formation stair shaft between stair activity, that section of distance grown is stair shaft width.
The precast stair of the utility model has the following beneficial effects:
Using factory's punching block one-pass molding, concreting in corresponding stairway die, transported after it meets intensity
The position subscribed to building site, in place by crane lifting, then with other building members splice, lifting construction efficiency, reduce construction
Duration reduces wet construction, energy-saving and emission-reduction, and for the stair of same gauge size, and the Novel staircase is more pre- than common
The weight saving of stair processed 30%~40%, avoids using large-scale tower crane equipment hoisting, also mitigates transport bring burden,
Inside setting plugging wire insulation board not only reduces weight, also saves material, reduces cost, and bring, which is marked time, when reducing walking stair makes an uproar
Sound.Stair waist slab is connect using lower end sliding hinged-support with platform simultaneously, can be avoided the formation of gangboard support, be weakened rigidity,
When being destroyed by seismic force, discharges destructive power of the earthquake and be unlikely to generate malformation even destruction.
