Abstract
The invention discloses a construction method of a waterproof roof. The construction method of the waterproof roof comprises the following steps that (1) a reinforced concrete roof is cleaned; (2) a slope is made on the reinforced concrete roof, and the gradient of the slope layer ranges from 2 percent to 3 percent; (3) a heat-preservation layer is laid on the slope layer; (4) the heat-preservation layer is leveled through cement mortar, and the leveling layer is 20-30 mm thick; (5) modified asphalt waterproof coiled materials are laid; (6) a protective layer is poured on the waterproof coiled material layer. The construction method of the waterproof roof is simple in process, is low in cost, largely improves the waterproof performance of the roof, and prolongs the service life of the waterproof roof.
Description
?
Technical field
The construction method that the present invention relates to a kind of water-proof roofing, belongs to technical field of building construction.
Background technology
Roof is that going along with sb. to guard him of covering effect and load-carrying members play in the house the superiors, and one of its topmost function is " rain of becalming ".Roofing, according to drainage grade difference, can be divided into flat roof deck and pitched roof.The gradient of general flat roof deck is below 10%, and the most frequently used gradient is 2 ~ 3%, and the gradient of pitched roof is more than 10%.China's building adopts pitched roof traditionally, has two-sided slope, slope, four sides etc.This roof pitch is larger, capable of expansion and contraction, and draining is rapid, waterproof effect is also relatively good.Since the sixties, for alleviating roofing deadweight, reduce construction costs, improving prefabricated roof assembling degree, generally change reinforced concrete flat roof into, adopt prefabricated circular hole roof panel and cast-in-situ steel reinforced concrete roof panel etc. more.Flat roof deck cost is lower, easy construction, simple structure, and outward appearance is succinct, is applicable to various shapes and big or small architectural plane, and current this class roofing is most widely used.
Once there is the situation that roof leakage rate is high in the building construction of China, has had a strong impact on the use function in house.Built house roofing generation leakage problem, directly have influence on people's life, working and learning, fundamentally solve built house roof leakage water problems, will set about from aspects such as the design of waterproofing, construction, material and management maintenances, carry out system management, integrated control.To improve waterproofing quality, stopping seepage is target, starts with from construction, maintains strict control over quality of materials pass, improves design level and strengthens management, and takes the concrete measures targetedly and carries out integrated control.
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 water-proof roofing is provided, the method is mainly by waterproof coiled material, and technique is simple, with low cost, and the water proofing property of roofing is greatly improved.
Technical scheme: the construction method of a kind of water-proof roofing of the present invention, comprises the steps:
(1) reinforced concrete roof is cleared up;
(2) reinforced concrete roof is looked for to slope, the sloping layer gradient is 2%-3%;
(3) on sloping layer, lay insulation layer;
(4) insulation layer is adopted to cement mortar screeding, levelling bed thickness 20-30mm;
(5) lay modified asphalt waterproof coiled material;
(6) on waterproof roll layer, build topping.
Further improve technique scheme, in described step (), reinforced concrete roof is assembled steel reinforced concrete slab, and the pea gravel concreten that adopts strength grade to be not less than C20 is filled with packing in fact by plate seam.
Further improve technique scheme, described step (four) adopts cement mortar screeding, and thickness is 20mm, and cement and mortar volume are frequently 1:2.5～1:3, and cement grade is more than or equal to 42.5, and is added with waterproof agent in described cement mortar.
Further improve technique scheme, in described step (five), coiled material laying direction is that parallel ridge is laid, and paving coiled material adopts splicing processes, and the lap side seam of levels and adjacent two width coiled materials should stagger.
Further improve technique scheme; the working procedure of described step (six) is: first at waterproof aspect upper berth 300mm × 300mm expanded perlite heat insulation; add in the above again one deck 3cm solid cement mortar cover; cloth gauze wire cloth in this layer; topping is established dividing joint; in seam, fill with encapsulant, protect better waterproofing course.
Compared with prior art, its beneficial effect is in the present invention: the construction method of water-proof roofing of the present invention, technique is simple, with low cost, and the water proofing property of roofing is greatly improved, and has extended the service life of water-proof roofing.
Detailed description of the invention
Below technical solution of the present invention is elaborated, but protection scope of the present invention is not limited to described embodiment.
embodiment 1:a construction method for water-proof roofing, is characterized in that, comprises the steps:
(1) reinforced concrete roof is cleared up;
(2) reinforced concrete roof is looked for to slope, the sloping layer gradient is 2%-3%;
(3) on sloping layer, lay insulation layer;
(4) insulation layer is adopted to cement mortar screeding, levelling bed thickness 20-30mm;
(5) lay modified asphalt waterproof coiled material;
(6) on waterproof roll layer, build topping.
Wherein: described step () is when reinforced concrete roof is assembled steel reinforced concrete slab, and the pea gravel concreten that adopts strength grade to be not less than C20 is filled with packing in fact by plate seam.
Described step (four) adopts cement mortar screeding, and thickness is 20mm, and cement and mortar volume are frequently 1:2.5～1:3, and cement grade is more than or equal to 42.5, and is added with waterproof agent in described cement mortar.
In described step (five), coiled material laying direction is that parallel ridge is laid, and paving coiled material adopts splicing processes, and the lap side seam of levels and adjacent two width coiled materials should stagger.
The working procedure of described step (six) is: at waterproof aspect upper berth 300mm × 300mm expanded perlite heat insulation; add in the above again one deck 3cm solid cement mortar cover, cloth gauze wire cloth in this layer, topping is established dividing joint; in seam, fill with encapsulant, protect better waterproofing course.
As mentioned above, although represented and explained the present invention with reference to specific preferred embodiment, it shall not be construed as the restriction to the present invention self.Not departing under the spirit and scope of the present invention prerequisite of claims definition, can make in the form and details various variations to it.
