Abstract
The invention belongs to a kind of precast prestressed cranked slab stairs of the structure of precast stair construction, the technical solution one that the present invention takes is：Waist slab is T plate, and the plate face of the T plate has two ribs, and the lower part of the rib is furnished with deformed bar.Technical solution two is：Waist slab uses cored slab, the bottom of the cored slab to be furnished with prestress wire.Which solve precast stair bench in assembled public building is long, from technical problem great, that component makes, transport and lifting are inconvenient.
Description
Technical field
The present invention relates to a kind of structure of building engineering field more particularly to precast stair constructions.
Background technology
The usual specification of precast stair is more unified, standardization level is high, is widely used in assembled-type house.However,
In public building, stair bench width and span are larger, and according to the full precast concrete of tradition, then stair dead weight is larger, gives
Making, transport, the lifting of component cause bigger difficulty.
Invention content
The technical problem to be solved in the present invention is to provide a kind of precast prestressed cranked slab stairss, and which solve assembled public affairs
Building together, it is long to build middle precast stair bench, from technical problem great, that component makes, transport and lifting are inconvenient.
The technical solution one that the present invention takes is：Waist slab is T plate, and the plate face of the T plate has two ribs,
It is furnished with deformed bar in the lower part of the rib.Stair stress form can be transformed into cranked slab stairs by this programme from stringer type stairway, can
It is effective to mitigate dead weight, control clear height.T plate both ends can routinely component layout be shelved on bracket or landing beam.
The technical solution two that the present invention takes is：Waist slab uses cored slab, the bottom of the cored slab to be furnished with prestressing force
Steel strand wires.
Beneficial effects of the present invention are：T plate has many advantages, such as that span is big, easy for construction, low cost；Cored slab have every
The advantages that sound is good, high capacity, big span.Stair dead weight can all be substantially reduced using precast prestressed cranked slab stairs, facilitate building
Making, transport and the lifting of ladder.
Description of the drawings
Fig. 1 is the schematic diagram of technical solution one in the present invention.
Fig. 2 is the schematic diagram of technical solution two in the present invention.
Specific implementation mode
For better understanding of the above-mentioned technical proposal of the present invention, carry out with reference to the accompanying drawings and examples further
Detailed description.
As shown in Figure 1, waist slab is T plate 1, i.e. plate face has two ribs, and cross sectional shape is double-T shape, under rib
Portion is furnished with deformed bar 3, and 1 both ends of T plate can routinely component layout be shelved on bracket or landing beam 2.
As shown in Fig. 2, a kind of precast prestressed cranked slab stairs, it is characterised in that：Waist slab is cored slab 4, described hollow
The lower part of plate is furnished with prestress wire, and 4 both ends of the cored slab routinely component layout can be shelved on bracket or landing beam 2
On.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention's
Technical solution, and be not used as limitation of the invention, any connotation based on the present invention is to embodiment described above
Made by variation, deformation, all will fall the present invention scope of the claims in.
Claims (2)
