For achieving the above object, the technical solution of the present invention is:
Three step construction methods on a kind of reinforced concrete stairs, it is characterised in that comprise the following steps:
A, stair template make, including template, side template bottom stair bench, dividing plate of marking time, dividing plate at construction joint, and drawable out moving module, described active module includes the 1st batten and the 2nd batten, 1st batten width >=50mm, thickness is with bottom template thickness, and length is with stair bench width；2nd batten width >=25mm, thickness is with bottom template thickness, and length is with stair bench width；Below above at 1st batten and at the 2nd batten, the justified margin on long limit, both sides, overlapping, connect fixing with nail；
The installation of template and reinforcing bottom b, the stair bench that will process according to drawing, including template bottom upper three steps, side template, wherein at construction joint divider upright in bottom template, 2nd batten of active module is embedded in the middle of the template of bottom, make the 2nd batten become a part for bottom template, and make the 1st batten be at construction joint at the intersection point of dividing plate and bottom template；
Other model sheetinstallat of c, stair and reinforcing, including stair step dividing plate；
After all model sheetinstallat of d, stair complete, when pouring This floor concrete, pour three step on stair, note vibrating the most closely knit；
E, dividing plate of stair side template and upper three steps being marked time after concrete final set are removed, but do not remove drawable out moving module；
F, stair side template and upper three steps mark time dividing plate removed after maintenance concrete immediately；
G, when last layer stair template construction, dividing plate of this floor side of the ladder mould and residue being marked time installs and reinforces；
If h stair joint part rubbish is more, drawable out moving module can be extracted out, expose owing to the 2nd batten detaches the refuse sweeping mouth of formation, again drawable out moving module be turned back to after having cleared up rubbish in situ；
I, when last layer concrete placings, stair are remained step and have poured, note vibrating the most closely knit；
J, after concrete final set, template is all removed, be careful not to destroy corner；
K, stair template carry out maintenance to concrete after having torn open immediately；
L, with 1:2 mortar by connect at the construction joint of stair bench stubble drawable out moving module position repair become band, it is ensured that the flatness after repairing.
On the reinforced concrete stairs of the present invention, three step construction methods can also be further achieved by the following technical measures.
Aforesaid method, the material of wherein said 1st batten is identical with bottom template.
Aforesaid method, the material of wherein said 2nd batten is identical with bottom template.
After using technique scheme, on the reinforced concrete stairs of the present invention, three step construction methods have the advantage that
1, drawable out moving modular structure is simple, easy to make, practical；
2, the quick rubbish such as dust, concrete slag, cigarette end at cleaning stair bench construction joint；
3, perception after stair form removal is promoted；
4, reduce later stage manual repair expense, reduce engineering cost.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
On the reinforced concrete stairs of the present invention, three step construction methods are for following sequence of construction:
Model sheetinstallat and reinforcing → reinforcing bar binding → side form bottom stair template making → stair bench, mark time dividing plate, at construction joint dividing plate and 50mm batten installation → concreting (being only poured into three steps to put) → stair template remove (50mm batten is not torn open with bed die) → maintenance → makings stair remainder mark time dividing plate and install → 50mm batten extracted out clear up rubbish after be inserted into original position → concreting (pour stair and remain step) → form removable (all dismountings) → maintenance → connect stubble with the repairing of 1:2 mortar and become band.
Three step construction method on the reinforced concrete stairs of the present invention, it is characterised in that comprise the following steps:
A, stair template make, including template 2, side template bottom stair bench, and dividing plate 6 of marking time, dividing plate 4 at construction joint, and drawable out moving module.
Referring now to the structural representation of three steps on the stair that Fig. 1 and Fig. 2, Fig. 1 are the embodiment of the present invention, Fig. 2 is the P position enlarged drawing in Fig. 1.As it can be seen, described active module includes the 1st batten the 1 and the 2nd batten 3, the wide 50mm of the 1st batten 1, thickness is with bottom template 2 thickness, and length is with stair bench width；The wide 25mm of 2nd batten 3, thickness is with bottom template 2 thickness, and length is with stair bench width；Below above at 1st batten 1 and at the 2nd batten 3, the justified margin on long limit, both sides, overlapping, connect fixing with nail；1st batten 1 is all identical with the material of template 2 bottom stair bench with the material of the 2nd batten 3.
The installation of template and reinforcing bottom b, the stair bench that will process according to drawing, including template 2 bottom upper three steps, side template, wherein at construction joint, dividing plate 4 is perpendicular to bottom template 2,2nd batten 3 of active module is embedded in the middle of the template 2 of bottom, make the 2nd batten 3 become a part for bottom template 2, and make the 1st batten 1 be at dividing plate at construction joint 4 and the intersection point of bottom template 2.
Other model sheetinstallat of c, stair and reinforcing, including stair step dividing plate 5.
After all model sheetinstallat of d, stair complete, when pouring This floor concrete, pour three step on stair, note vibrating the most closely knit.
E, dividing plate of stair side template and upper three steps being marked time after concrete final set remove 5, but do not remove drawable out moving module；
F, stair side template and upper three steps mark time dividing plate removed after maintenance concrete immediately.
G, when last layer stair template construction, dividing plate of this floor side of the ladder mould and residue being marked time installs and reinforces.
If h stair joint part rubbish is more, drawable out moving module can be extracted out, expose owing to the 2nd batten 3 detaches the refuse sweeping mouth of formation, again drawable out moving module be turned back to after having cleared up rubbish in situ；Fig. 3 is the stair template floor map of the embodiment of the present invention.
I, when last layer concrete placings, stair are remained step and have poured, note vibrating the most closely knit.
J, after concrete final set, template is all removed, be careful not to destroy corner.
K, stair template carry out maintenance to concrete after having torn open immediately.
L, with 1:2 mortar by connect at the construction joint of stair bench stubble drawable out moving module position repair become band, it is ensured that the flatness after repairing.
The present invention has substantive distinguishing features and significant technological progress, three step construction method on the reinforced concrete stairs of the present invention of the present invention, use active module structure dexterously, beyond thought work efficiency is produced in construction, reach quickly to clear up the rubbish such as dust, concrete slag, cigarette end at stair bench construction joint, promote perception after stair form removal, reduce later stage manual repair expense, reduce engineering cost.
On the reinforced concrete stairs of the present invention, three step construction methods dispose in cellular engineering Bangbu Qin market town peasant and use, and construction method is simple, with low cost, it is easy to operation, and effect is notable, have obtained exploiting entity, supervisor and owner's abundant affirmation.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, it is also possible to make various conversion or change.Therefore, the technical scheme of all equivalents also should belong to scope of the invention, should be limited by each claim.
