Description
Technical field
The invention belongs to the realm of building construction, be specially a kind of concrete construction process of wide-angle pitched roof.
Background technology
The many employings of existing pitched roof concrete construction technology make real process or adopt double-deck wooden form after vibrating, prior art by roofing angle limits cannot be vibrated, concrete very easily glides accumulations, time of building long, the surperficial bad control of planeness, secondary roofing mortar or phenomenon, expense of the taking a lot of work material such as fine-stone concrete is levelling.
Summary of the invention
The object of this invention is to provide a kind of concrete discharging easily, facilitate vibration compacting and control thickness of slab, surfacing without the need to the concrete casting building technology of the levelling wide-angle pitched roof of secondary.
Realize the technical scheme of above-mentioned purpose: the concrete casting building technology of wide-angle pitched roof, is characterized in that, its concrete technology step:
1) pitched roof bottom wooden form is laid, and the good reinforcing bar of colligation; .
2) guide rail that the many groups of channel-section steels relative by two openings arranged to Po Ding direction at the bottom of slope form is fixed with successively from bottom wooden form left end to right-hand member, distance between two channel-section steels is no more than 2.5m, without pitch arrangement between two adjacent groups guide rail, be connected by sealing up screw between channel-section steel with bottom wooden form, leave gap between channel-section steel and bottom wooden form, the size in gap is identical with concrete thickness to be poured;
3) in the guide rail often organizing channel-section steel composition, install steel form, steel form is all provided with form vibrator, and steel form is placed in one end at the bottom of the slope of respective carter;
4) lifting gear is all installed in roof, for driving corresponding steel form along slide often organizing above guide rail;
5) concreting between two channel-section steels often organizing guide rail, builds and carries out successively from the bottom to top, and concrete edge blowing limit small vibrating rod vibrates, and starts form vibrator simultaneously, guarantees concrete compaction;
6) after concreting 15 minutes, start lifting gear and drive steel form upwards sliding, every 15min upwards promoted once, calculates promote 30-40cm at every turn with roofing plagioclase;
7) steel form is sliding push up to slope after carry out secondary by artificial traditionally method again and polish process;
8) guide rail, steel form, vibrator and lifting gear after having built is removed, and by floating for the concrete below the guide rail of dismounting;
9) guide rail, steel form, vibrator and the lifting gear step 8) removed are by step 2)-4) install successively on the right side of the guide rail of low order end, until cover the bottom wooden form on whole roofing, after installation, repeat step 5)-8).
Above-mentioned steps 3) in install before steel form, coating lubricating oil in two channel-section steels often organizing guide rail.
Lifting gear in above-mentioned steps 4 is bottle gouard moved by hands or electric block.
The invention solves in existing normal pitched roof concrete placings process, cannot vibrate, concrete very easily glides accumulation, the bad control of planeness that the time of building is long, surperficial, secondary roofing mortar or the phenomenon such as fine-stone concrete is levelling.
The present invention improves conventional double wooden form construction technology, make concrete discharging easily, should vibration compacting, should thickness of slab be controlled, surfacing is levelling without the need to secondary, decrease the waste of timber, improve the turnover utilization rate of material, and construction quality and molding effect increase substantially.
Accompanying drawing explanation
Fig. 1 is the front view of duty of the present invention;
Fig. 2 is the lateral view of duty of the present invention.
Detailed description of the invention
Below in conjunction with Fig. 1,2, processing step of the present invention is illustrated:
1) pitched roof bottom wooden form 1 is laid, and the good reinforcing bar of colligation.
2) guide rail 3 that three groups of channel-section steels 2 relative by two openings arranged to Po Ding direction at the bottom of slope form is fixed with successively from bottom wooden form 1 left end to right-hand member, distance between two channel-section steels 2 is no more than 2.5m, without pitch arrangement between two adjacent groups guide rail 3, be connected by sealing up screw 4 between channel-section steel 2 with bottom wooden form 1, the two ends of sealing up screw 4 are respectively arranged with the catch 5 of the spacing for limiting channel-section steel 2 and bottom wooden form 1, the two ends of sealing up screw 4 are fixed by nut 6 through after channel-section steel 2 and bottom wooden form 1, distance between the two ends catch 5 of sealing up screw 4 is identical with concrete thickness to be poured.
3) equal coating lubricating oil in two channel-section steels 2 of three groups of guide rails 3, in the guide rail 3 that three groups of channel-section steels 2 form, all install steel form 7, steel form 7 is all provided with form vibrator 8, and steel form 7 is placed in one end at the bottom of the slope of respective carter 3.
4) above three groups of guide rails 3, bottle gouard moved by hands 9 all being installed on roof, sliding along guide rail 3 for driving corresponding steel form 7.
5) concreting 10 between two channel-section steels 2 often organizing guide rail 3, builds and carries out successively from the bottom to top, and blowing limit, concrete 10 limit small vibrating rod vibrates, and starts form vibrator 8 simultaneously, guarantees concrete compaction.
6) after concreting 15 minutes, start bottle gouard moved by hands 9 and drive steel form 7 upwards sliding, every 5min upwards promoted once, calculates promote 30-40cm at every turn with roofing plagioclase.
