Abstract
The invention discloses a method for constructing a foamed concrete roof insulation layer. The constructing method is characterized in that (1) thicknesses and technical requirements of a waterproof roll, a rolled waterproof material and a leveling layer used for a foamed concrete roof insulation system, and thicknesses of a basement layer treating agent, a pressing seam adhesion agent, a sealing material and a membrane waterproof layer used for a rolled waterproof pad meet national norms and regulations; (2) during concrete casting, regression operation is performed sequentially to prevent from disturbance, the foamed concrete surface is polished and jointed before initial set, and the distance from a discharge hole to a basement layer is not too tall; during large-area concrete casting, a method for gradually casting concretes by dividing zones is adopted and the once concrete casting height is not beyond 20cm, and the concrete is twice cast after initial set; (3) the concrete is cured after final set; (4) points warehouse seams are cut. The constructing method has the advantages that: firstly, selecting and using standards of constructing raw materials are strict, namely excellent raw materials are selected from good ones; secondly, fine constructing processes are present; thirdly, technological parameters are rigorous, scientific and standardized.
Description
Technical field
The present invention relates to a kind of construction method of roofing heat-insulating layer, particularly a kind of construction method of foam concrete roofing heat-insulating layer.
Background technology

Summary of the invention
The object of the present invention is to provide a kind of raw material of constructing select strict, technique is meticulous, the construction method of the foam concrete roofing heat-insulating layer of technological parameter rigorous and scientific specification.
The technical solution used in the present invention is, the construction method of this foam concrete roofing heat-insulating layer:
(1) all kinds of waterproof rolls of foam concrete roof heat insulation system use, its presentation quality and physical property should meet the regulation of appendix A .0.1 in " roofworks inspection of quality specification " (GB50207-2002), all kinds of water-repellent paints that foam concrete roof heat insulation system uses, the regulation of appendix A .0.2 during its physical property should meet " roofworks inspection of quality specification " (GB50207-2002), the thickness of leveling layer and technical requirements should meet the regulation of annex 4.1.2 in " roofworks inspection of quality specification " (GB50207-2002), foam concrete roof heat insulation layer thickness should meet designing requirement, when build highly be greater than 20cm time, whether placement layer by layer should be selected according to actual conditions, base treatment agent selected by coil waterproof layer, by seam bonding adhesive, encapsulant should be compatible with the coiled material wood property of laying, coil thickness selects the regulation that should meet 5.3.2 in " Technical code for roof engineering " (GB50345-2004), coating waterproofing layer thickness selects the regulation that should meet 6.3.2 in " Technical code for roof engineering " (GB50345-2004),
(2) when building, should be regressed operation in order, prevent disturbance, avoid causing harmful effect to it, carry out drawing light to tie face before the non-initial set in foam concrete surface, discharging opening should not be too high from basic unit, prevent brokenly bubble, must not more than 1m, when large area is built, the method that subregion is built piecewise can be adopted, by template, working face is separated into some small pieces, construct piecewise, one-time-concreting height, no more than 20cm, in order to avoid the excessive and broken bubble of bottom foam concrete slurry pressure-bearing, can after initial set, carry out secondary to build, design draining ramp and planeness will be checked before final set, if any deviation, need to revise in time,
(3), after building, want static before final set, must not disturbance and people can not be gone up, can not load-bearing, maintenance is started, maintenance in summer 3-5 days, Maintenance in Winter 5-7 days after foam concrete final set, after having upper people's intensity, can adopt the moisture-keeping maintaining that suitably waters, winter can not water seasoning;
(4) parting seam is cut: after foam concrete final set, portable cutting machine is adopted to carry out the cutting of parting seam, the interval of parting seam should not be greater than 6m, the width 2-3cm of parting seam, the degree of depth is preferably between the 1/2-2/3 of cast thickness, before cutting, should the good line of ink marker of bullet, clean out in groove after cutting, the stone being no more than 16mm with particle diameter is filled and led up, and groove covers joint seal lath, prevents leveling mortar from infiltrating in parting seam, steam vent is set by designing requirement, can makes of UPVC pipe or galvanized pipe.
Owing to taking technique scheme, therefore the present invention has the following advantages: one is strict to the raw-material choice for use standard of construction, selects excellent in accomplishing.Such as waterproof roll, water-repellent paint, base treatment agent, by seam bonding adhesive, encapsulant etc. all to meet national technical standard code requirement.Two is that construction technology is meticulous.Each step for construction early stage, mid-term, later stage and curing time has all made detailed code requirement.Three is technological parameter rigorous and scientific specifications.For foam concrete roof heat insulation layer thickness, build height, build area, build number of times, coating waterproofing layer thickness, curing requirements, the technical data rigorous and scientific specification all in addition such as cutting parting seam.
