Abstract
The utility model discloses a section-prefabricated concrete stair which comprises a stair section with a triangular step boards and an inclined stair beam which is arranged at the outer side of the stair section. A rectangular bulge at the upper end of the stair section is provided with upper connecting reinforcing bars, the parts of the upper connecting reinforcing bars in the stair section are mutually parallel, right-angled downward bends are arranged at the tail ends of the upper connecting reinforcing bars, and the parts of the upper connecting reinforcing bars outside the stair section are enclosed U-shaped; and lower connecting reinforcing bars are arranged at the lower ends of the stair section. The section-prefabricated concrete stair has the advantages of low material consumption, low cost and convenience in installation.
Description
Technical field
The utility model relates to the building unit field, particularly a kind of prefabricate concrete staircase.
Background technology
Existing concrete staircase, general cast-in-place making, though its globality is better, its reinforcing bar materials are many, cost is high, and site construction technology is complicated, and engineering is heavy, has influenced the duration.
Summary of the invention
In order to address the above problem, the utility model provides the novel prefabricate concrete staircase that a kind of reinforcing bar materials are few, cost is low, easy for installation.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of prefabricate concrete staircase, it comprises:
The staristep that has the triangle step plate; The rectangle projection of this staristep upper end is provided with connecting reinforcement; Should go up the parallel to each other and terminal downward bending of part that connecting reinforcement is positioned at said staristep, be positioned at the outside part of said staristep " U " shape for sealing with right angle; Said staristep lower end is provided with down connecting reinforcement;
The ladder cant beam is located at the said staristep outside.
Said connecting reinforcement down has the bending at right angle, one side being positioned at outside the said staristep of right angle is provided with vertically downward.
The part that said connecting reinforcement down is positioned at said staristep has the bending identical with the horizontal direction angle with said staristep, is positioned at the outside part of said staristep " U " shape for sealing.
Be interval with the guardrail groove at said terraced cant beam end face, be provided with pre-embedded steel slab in this guardrail groove.
The place is provided with 2 to 3 road antiskid grooves in said staristep triangle step plate upper surface leading edge.
Establish around reinforcing rib in the said terraced cant beam, said staristep inside is provided with straight reinforcing rib near the position of said triangle step plate.
The beneficial effect of the utility model is: the utility model can effectively connect cast-in-place or prefabricated floor platform and halfpace, and more convenient and quicker is installed, can accelerating construction progress.The sliding groove of setting up defences in it has improved the functional performance of stair.
