Description
Technical field
The construction method that the present invention relates to a kind of roof heat insulation isolation layer, belongs to technical field of building construction.
Background technology
At present, China has higher requirement to the thermal and insulating performance of building construction, even and at present a lot of townsfolks building is all or simple flat-top room.Outer insulation is a kind of building thermal-insulation energy-saving technology of wideling popularize at present.Outer insulation is compared with interior insulation, and technology is reasonable, has its obvious superiority, uses the heat insulating material of same specification, same size and performance, and outer insulation is more effective than interior insulation.Outer heat preservation technology is not only applicable to newly-built Structural Engineering, is applicable to old building transforming yet, is applicable to scope wide, with high content of technology; Outer insulation wraps in the outside of agent structure, can protect agent structure, extends the life-span of building; Effectively reduce the heat bridge of building structure, increased the usefull space of building; Eliminate condensation simultaneously, improved the comfort level of living.According under the guidance of a series of energy saving policy, rules, standard and compulsive clause, the energy conservation of China's dwelling construction deepens continuously, energy conservation standard improves constantly, and introduces and has developed many novel power-saving technologies and material, in housing construction, vigorously promotes the use.But the building energy conservation level that China is current, also far below developed country, China's construction unit area energy consumption is still 3 times ~ 5 times of developed country that weather is close.The building heating energy consumption of north cold area has accounted for the more than 20% of local whole society energy consumption, and the overwhelming majority is all to adopt thermal power generation and coal-burning boiler, brings serious pollution to environment simultaneously.So building energy conservation or this century Building Trade in China an important problem.And while body of wall and roof are as the important object of going along with sb. to guard him of building, and its insulation layer thickness is the important parameter that is decided by building heat preservation level, so for strengthening heat-insulating property and saving heat-energy losses and energy waste, design best insulation layer thickness and have great significance.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, a kind of construction method of roof heat insulation isolation layer is provided, this construction method easy construction, normative and reasonable, has reduced construction cost, and the heat insulating effect of roofing can be effectively provided simultaneously.
Technical scheme: the construction method of a kind of roof heat insulation isolation layer of the present invention, comprises the steps:
(1) base cleaning: prefabricated or cast-in-place concrete structure layer surface, foreign material, dust should be cleaned out;
(2) snap the line is looked for slope: by design grade and current direction, find out roof pitch trend, determine the thickness range of insulation layer;
(3) pipe root is fixed: wear the pipe root of structure before insulation layer construction, application pea gravel concreten plug is stifled closely knit;
(4) vapour barrier construction: do vapour barrier by design, brushing is evenly without leaking brush;
(5) insulation layer is laid: the intensity of heat insulating material, density, coefficient of thermal conductivity and moisture content, must meet the regulation of designing requirement and construction and standards of acceptance;
(6) cement mortar screeding: after insulation layer has been constructed, should spread in time and smear cement mortar screeding layer, to guarantee heat insulation effect.
Further improve technique scheme: described step (five) adopts loose expanded vermiculite, and vermiculite particle diameter is 3～15mm, during laying, make the bedding plane of expanded vermiculite vertical with hot-fluid.
In described step (five), insulation layer is loose insulation layer, material is slag or grain slag, particle diameter is 5～40mm, during use, must sieve, control moisture content, the body structure surface of laying discrete material should be dried, cleaning, and loose fill type insulant answers layering to lay, appropriate compacting, every step laying depth is less than 150mm.
Described step (five) adopts loose expanded perlite, and the content that perlite particle diameter is less than 0.15mm must not be less than 8%.
, the described insulation layer of described step (five) is laid and is adopted dry bed board block insulation layer, is laid immediately on deck or vapour barrier, and when layering is laid, upper and lower two-layer plate seam should stagger, and the two adjacent edges of boards thickness in surface should be consistent.
The described insulation layer of described step (five) is laid and is adopted bonding to lay plate-like insulation layer, and plate-like heat insulating material is bonded on roof-base with binding material is flat, and adhesives is cement, lime composite mortar.
The described insulation layer of described step (five) is laid and is adopted cement lime slag insulation layer: with whitewash, slag is vexed before construction, before vexed system, slag or grain slag should be sieved, particle diameter is 5～40mm, then mechanical agitation, lay layered, roll extrusion, control the density of virtual resurfacing thickness and designing requirement, guarantee heat-insulating property.
The described insulation layer of described step (five) is laid and is adopted cement vermiculite insulation layer, take expanded vermiculite for gathering materials, cement is cementitious material, expanded vermiculite particle diameter is 5～20mm, by cement paste equably not on quantitative vermiculite, with sprinkling with mixing until evenly, with wooden bat plate make real, levelling
Compared with prior art, its beneficial effect is in the present invention: the construction method of roof heat insulation isolation layer of the present invention, and easy construction, normative and reasonable, has reduced construction cost, and the heat insulating effect of roofing can be effectively provided simultaneously.
