Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
The technological process of cast-in-situ steel reinforced concrete waffle beam floor construction method of the present invention is as follows:
, (reinforced concrete post has been constructed) → line setting → set up scaffold support system, (full hall scaffold) → Vierendeel girder formwork, (common templates) → waffle beam floor shop fixtures mould, (common wooden model) → Vierendeel girder reinforcing bar binding → waffle beam Template Location unwrapping wire → waffle beam template, (vinyon formwork) installation → waffle beam template examination → waffle beam reinforcement installation → floor bar is installed, (being generally individual layer reinforcing bar) → mounting electrical pipeline and built-in fitting → subsurface work acceptance → concreting → maintenance → form removal.
Cast-in-situ steel reinforced concrete waffle beam floor construction method of the present invention, comprises the following steps:
A, set up support system and template
(1) on structural plane, pop-up box is set a roof beam in place axis, determines Support Position;
(2) scaffold support system of steel scaffold upright rod, steel (wood) keel composition is adopted;
Wherein: setting up order is: put in length and breadth to bottom pull bar → establish bar (bottom of upright rod load onto regulate collet) by root, to absolute altitude → laying in the groove of the bridging → installation jacking of pull bar and necessity → correct according to the absolute altitude of precalculated jacking jacking, main joist (wooden H-beam) → install secondary joist (flitch or a few word beam of aluminium alloys) secondary joist spacing 30cm → laying Vierendeel girder bed die on main joist is installed in length and breadth with bottom pull bar fastening → installations upper strata immediately and girt strip bed die (normal wood template) → correction box is set a roof beam in place and girt strip elevation of bottom;
