Abstract
The invention relates to a method for casting a concrete ceiling with a smooth surface once, which is characterized by comprising the following steps: firstly, splicing shuttering boards to form a mould board, fixing the mould board by a support frame, and laying a plastic film or a piece of waterproof cloth on the mould board; secondly, casting gypsum on the plastic film, trimming the gypsum after the gypsum is solidified to make the surface of the mould board flat and smooth; and finally, laying and filling a wall plastering layer on the gypsum layer, casting reinforced concrete after the wall plastering layer is solidified, removing the mould board after the concrete is hardened, and chiseling the gypsum layer. Because the gypsum is used for covering the surface of the mould board and for late stage trimming, the method provides a smooth and flat reference plane, and ensures flatness of the cast ceiling; moreover, the wall plastering layer is laid and filled in advance and finally cast with the concrete together to form a whole, so the bonding strength among layers is high; and after the casting, construction for plastering wall surfaces is not needed, so the method reduces work intensity of workers greatly.
Description
Technical field
The present invention relates to the method for building operations, particularly to the improvement of concrete ceiling pouring procedure.
Background technology
At present, the ceiling of cast building is the equal-sized template of ceiling of splicing composition and required cast earlier with the polylith shuttering, fixes with bracing frame and ground below, promptly twist the fixed mount fixed form, on template, carried out the cast of concrete ceiling again.
Because it is smooth fully that template can't be accomplished, thereby cast ceiling bottom surface well is uneven, need whitewash.With fine sand and cement mixing, cover the ceiling surface when whitewashing, in order to strengthen the adhesion between rendering layer and ceiling, also will apply glue in the ceiling bottom surface in advance sometimes.Construction sequence complexity like this, labour intensity is big when whitewashing, and the adhesion between rendering layer and ceiling is poor.
Summary of the invention
The object of the invention is to provide a kind of rendering layer and ceiling to form the ceiling pouring procedure of one, with the intensity of increase ceiling, and reduces the later stage operation, reduces labour intensity.
The solution of the present invention is: the method for the concrete ceiling of disposal pouring smooth surface, it is characterized in that: form template with the shuttering splicing earlier, and fix with bracing frame, on template, spread plastic sheeting or canvas cloth, again pouring gypsum on plastic sheeting, Deng gypsum curing back it is repaired, make its surfacing smooth, fill out the wall plaster layer on the gypsic horizon upper berth then, carry out the cast of steel concrete after waiting it to solidify again, stripping after the hardening of concrete, and gypsic horizon cutter gone.
Advantage of the present invention is: owing to gypsum template surface is covered, and carry out the later stage finishing, smooth smooth datum is provided, guaranteed ceiling smooth after pouring into a mould; In addition, the wall plaster layer is spread in advance and is filled out, and is in the same place with concrete pouring at last, forms integral body, the bond strength height of interlayer; After cast is good, no longer need the construction of wall plaster, greatly reduce working strength of workers.
The specific embodiment
The invention will be further described according to embodiment below.
The working procedure that embodiment adopts is as follows:
1. form template with shuttering in the splicing of needs cast ceiling place, fix with bracing frame and ground supports below the template.
2. spread plastic sheeting or canvas cloth on template, seam crossing is glued, and prevents to leak.
3. pouring gypsum on plastic sheeting, gypsum adopt and solidify the plaster of paris slowly and water mixes the sposh shape, make it have flowability, and when watering gypsum, the surface is the smooth horizontal plane of formation naturally.If by the injustice place, wait gypsum to solidify the back it is repaired, make its surfacing smooth.
4. fill out the wall plaster layer on the gypsic horizon upper berth, adopt fine sand and cement mixing, the shop is filled out on gypsic horizon, thickness 2-3cm, and even with the vibration pump vibrations when shop is filled out, upper surface carries out coarse processing, with the adhesion of increase and smallpox flaggy.The granular size of fine sand and with the ratio of cement mixing with whitewash at present metope require identical.
5. after the wall plaster layer solidifies, on this wall plaster layer, carry out the cast of steel concrete again, make the ceiling body.The job practices of this operation is with the cast ceiling is identical now.
6. stripping after the hardening of concrete, and the gypsic horizon cutter gone.
The ceiling that this method makes, the bottom surface is smooth smooth, and rendering layer and ceiling bulk junction are made a concerted effort strong.Owing to do not need to carry out the wall plaster in later stage, if when finishing to its oil surface lacquer, solved whitewash in the past the ceiling workman face upward an operation can't the application of force, the problem that labour intensity is big.
