Description
Technical field
The present invention relates to a kind of concrete terrace construction method, specifically, is a kind of large-area concrete ground preparation method.
Background technology
Because large area globality concrete rigid terrace rose in recent years, its surface (as epoxy floor etc.) moulds light way, to large area globality concrete rigid terrace surface flatness requirement increasingly stringent.Common traditional construction method is: control as absolute altitude with reinforcing bar, by floating rule (or cylinder) control surface planeness.But there is following shortcoming in traditional large-area concrete ground construction method:
1, in large-area concrete ground construction, floating rule (or cylinder) paste effect is bad, when carrying out surface grinding, because cement paste does not fully put forward, and local sand return, breakage when causing Large Rigid terrace surface to be polished.
2, because floating rule (or cylinder) deadweight is comparatively light, friction load, floating rule (or cylinder) and absolute altitude control reinforcing bar gap, causes large-area concrete rigidity terrace surface finish cannot meet specification or designing requirement.Fig. 1 is the partial waveform phenomenological structure schematic diagram that the known large-area concrete ground construction method of the present invention produces.
3, because reinforcing bar flexibility is comparatively large, control local, concrete floor surface with reinforcing bar as absolute altitude and there will be waveform phenomenon, have a strong impact on surface finish.
Therefore the control of known domestic conventional construction method to large area globality rigidity terrace surface finish also exists above-mentioned all inconvenience and problem.
