Abstract

The invention belongs to a kind of precast prestressed concrete stair in the prefabricated construction of building engineering field, including stair step, gangboard and the ribbing beam under the gangboard, the gangboard to be made of inclined ladder section and platform section, and deformed bar is configured in the ribbing beam.It solves in cranked slab stairs gangboard to conduct oneself with dignity the higher technical problem of ribbing beam deck-molding in larger or stringer type stairway.

Description

A kind of precast prestressed concrete stair
Technical field
The present invention relates to a kind of structure of building engineering field more particularly to prefabricated components constructions.
Background technology
It is in the prior art non-prestressed cranked slab stairs or non-prestressed beam type to the common practice of precast concrete stair Stair.The existing structure of non-prestressed stringer type stairway is that gangboard is arranged on ribbing beam, and load is passed to by gangboard on ribbing beam.But In partly building, because of building function requirement, gangboard span needs are accomplished very greatly, to lead to the larger or beam of gangboard dead weight in cranked slab stairs Ribbing beam deck-molding is higher in formula stair, influences to build clear height, constrains application of the precast stair in assembled architecture.
Invention content
The technical problem to be solved in the present invention is to provide a kind of precast prestressed concrete stair, and which solve slab-type apartment buildings The higher technical problem of ribbing beam deck-molding in the larger or stringer type stairway of gangboard dead weight in ladder.
The technical solution that the present invention takes is:A kind of precast prestressed concrete stair, including stair step, gangboard and position Ribbing beam under the gangboard, the gangboard are made of inclined ladder section and platform section, and deformed bar is configured in the ribbing beam.
In above-mentioned technical proposal, the quantity of inclined ladder section and platform section is unlimited, can be according to actual requirement of engineering flexible combination.
Beneficial effects of the present invention are:Mitigate gangboard dead weight, is easy to lift, realizes energy saving purpose;Ribbing beam is using pre- Stress reinforcing bar effectively reduces deck-molding, reduces stair amount of deflection and crack.
Description of the drawings
Fig. 1 is the sectional view of precast prestressed concrete stair in the present invention.
Fig. 2 is the stereoscopic schematic diagram of 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 depicted in figs. 1 and 2, precast prestressed concrete stair include stair step 1, gangboard 2 and under gangboard 2 Ribbing beam 3, gangboard 2 are made of inclined ladder section 4 and platform section 5, and deformed bar is configured in ribbing beam 3.
Ribbing beam 3 can be two be arranged symmetrically, or centre one is a plurality of.It only needs to meet stair Load force request.
The combination of inclined ladder section 4 and platform section 5 determines that quantity is unlimited according to Practical Project.It can be different by multiple slopes Inclined ladder section 4 and multiple platform sections 5 are freely combined.
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.
