Abstract
A kind of steel stair is marked time external angle formwork, and it comprises girder steel and collet, and girder steel upper and lower side is respectively equipped with collet, and collet is provided with adjusting bolt; Steel beam bottom establishes some templates of marking time; Template of marking time is made up of mark time external corner chamfering formwork and back cord template.The utility model steel stair template of marking time has stopped the phenomenon of stair step external corner losing fangle, improves engineering entity impression quality; Save nail, tear the artificial of protection corner for stair step mould and Master Cost open.
Description
Technical field
The utility model relates to civilian construction stair, particularly relates to a kind of steel stair and to mark time external angle formwork.
Background technology
For the common quality defect of stair step external corner cracky in the major project that solution is constructed before; the steel template of stair step external corner part is reformed and improved; solve the quality problems of stair step external corner losing fangle, save the expense that staircase external angle carries out protecting simultaneously.The popularization of this technique, makes stair step entity impression quality be improved significantly, and to the overall impression quality of raising engineering, improves construction enterprises' image and has and act on significantly.
Utility model content
The purpose of this utility model is to overcome problems of the prior art, provides a kind of steel stair to mark time external angle formwork.
A kind of steel stair of the present utility model is marked time external angle formwork, and it comprises girder steel and collet, and girder steel upper and lower side is respectively equipped with collet, and collet is provided with adjusting bolt; Steel beam bottom establishes some templates of marking time; Template of marking time is made up of mark time external corner chamfering formwork and back cord template.
The utility model compared with prior art has the following advantages:
1, the utility model steel stair template of marking time has stopped the phenomenon of stair step external corner losing fangle, improves engineering entity impression quality.
2, the utility model steel stair is marked time the use of template, external corner part floated coat of marking time when decorative engineering is plastered thickens, facade and plane floated coat globality strengthen, and improve external corner intensity, reduce in work progress because collision causes the common quality defect of losing fangle.
3, the utility model saves nail, tears the artificial of protection corner for stair step mould and Master Cost open.
4, the utility model is compared with wooden form, can improve work efficiency 60%.
5, the utility model simple, convenient, be easy to sizing produce; Meanwhile, the utility model can have enough to meet the need use, not only economy but also environmental protection, and stair step entity impression quality is improved significantly, and has remarkable effect to the overall impression quality of raising engineering, raising construction enterprises image.
Accompanying drawing explanation
Below in conjunction with accompanying drawing to the further detailed description of detailed description of the invention of the present utility model.
Fig. 1 is the utility model structural representation.
In figure: 1-template of marking time, 2-girder steel, 3-external corner chamfering formwork 4-back cord template of marking time, 5-adjusting bolt, 6-collet.
Detailed description of the invention
A kind of steel stair as Fig. 1 is marked time external angle formwork, and it comprises girder steel 2 and collet 6, and girder steel 2 upper and lower side is respectively equipped with collet 6, and collet 6 is provided with adjusting bolt 5; Some templates 1 of marking time are established bottom girder steel 2; Template of marking time 1 is made up of mark time external corner chamfering formwork 3 and back cord template 4.
During installation, be lifted on stair step position by tower crane, controlled by adjusting bolt 5.Mark time concrete placings time equal with concrete surface template of marking time, and with the thin plucking of water brush after plasterer's trowel press polish.When template of marking time 1 is removed, first adjusting bolt 5 is loosened and make template and concrete surface leave about 10mm, after stair step concrete strength increases, hang template again.
