Abstract
The utility model discloses a kind of prefabricated assembled anti-skidding stair, including half space and the bench being provided with continuous step, it is provided with steel bar stress in described half space, described bench is provided with installing hole on first step and last step, described half space is provided with the reinforcing bar matched with installing hole on step, being achieved a fixed connection by installing hole and reinforcing bar between described bench and half space, the step of described bench is provided with anti-skidding raised line.Use assembled in situ mode to connect between described bench and half space, reduce work on the spot intensity, shorten construction period, largely reduce the pollution level of job site；Described anti-skidding raised line improves the anti-skidding grade of step, improves safety coefficient.
Description
Technical field
This utility model relates to construction engineering technical field, is specifically related to a kind of prefabricated assembled anti-skidding stair.
Background technology
Stair traffic connection between the floor or when the discrepancy in elevation is bigger, though be provided with elevator, autostairs as the multilamellar of main vertical transportation means and skyscraper in stair to be retained for fire time escape be used.The construction of existing stair still uses traditional cast-in-place mode; the reasons such as work on the spot amount is big, construction material utilization rate is low, building water waste, environmental pollution are serious that use this mode to exist; do not meet energy-saving and emission-reduction and the requirement of protection environment; the most existing stair itself do not have antiskid function, there is certain potential safety hazard.
Utility model content
In order to overcome prior art not enough, this utility model provides a kind of prefabricated assembled anti-skidding stair, it is therefore an objective to reduces work on the spot amount, the utilization rate of raising construction material, reduce environmental pollution, improves the non-skid property of stair simultaneously.
Technical solution of the present utility model: a kind of prefabricated assembled anti-skidding stair, including half space and the bench being provided with continuous step, it is provided with steel bar stress in described half space, it is characterized in that: described bench is provided with installing hole on first step and last step, described half space is provided with the reinforcing bar matched with installing hole on step, being achieved a fixed connection by installing hole and reinforcing bar between described bench and half space, the step of described bench is provided with anti-skidding raised line.
Preferred described half space and bench are provided with hole for hoist.
Preferred described steel bar stress double-layer double-direction is distributed in half space, all includes lateral stressed reinforcing bar and the Reinforcement arranged up and down in each layer.
Preferred described step is provided with two anti-skidding raised lines and is provided close to the position outside step.
Preferred described half space both sides are provided with shearing resistance groove.
The beneficial effects of the utility model: bench described in this utility model and half space use factory industry metaplasia to produce, are conducive to improving the quality of product；Use assembled in situ mode to connect between bench and half space, reduce work on the spot intensity, shorten construction period, largely reduce the pollution level of job site；Described anti-skidding raised line improves the anti-skidding grade of step, improves safety coefficient；Described shearing resistance groove is conducive to increasing the shear-carrying capacity of half space end.

Wherein: 1 step 1a first paragraph step 1b final stage step 2 lateral stressed reinforcing bar 3 anti-skidding raised line 8 hole for hoist of Reinforcement 4 shearing resistance groove 5 reinforcing bar 6 installing hole 7.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
A kind of prefabricated assembled anti-skidding stair, including half space and the bench being provided with continuous step 1.It is provided with steel bar stress in described half space, described steel bar stress double-layer double-direction is distributed in half space, lateral stressed reinforcing bar 2 and the Reinforcement 3 arranged up and down is all included in each layer, half space both sides are provided with shearing resistance groove 4, the design of shearing resistance groove 4 adds the shear-carrying capacity of half space end, and half space is provided with reinforcing bar 5.Described bench is provided with, on first paragraph step 1a and final stage step 1b, the installing hole 6 mated with the reinforcing bar 5 on half space, achieved a fixed connection by installing hole 6 and reinforcing bar 5 between described bench and half space, during site operation, after half space and bench are connected by installing hole 6 and reinforcing bar 5, pea gravel concreten is poured again, after concrete reaches desired strength in installing hole.The step 1 of described bench is provided with two anti-skidding raised lines 7, described anti-skidding raised line is provided close to the position outside step 1, the design of anti-skidding raised line 7 adds the anti-skidding grade of bench, improve the safe class of stair, in the present embodiment, each bench is in addition to first paragraph step, and each step is equipped with anti-skidding raised line.It is additionally provided with hole for hoist 8 on described half space and bench, work progress utilizes hole for hoist 8 half space and bench are lifted, convenient construction.Half space described in this utility model and bench are factory industry metaplasia and produce, and are conducive to improving the quality of product, reduce site operation intensity and pollution, shorten the site operation cycle simultaneously.
To sum up, this utility model produces a desired effect.
