The green leakage-proof roofing
The present invention relates to a kind of leak-proof roof, especially have the leak-proof roof of afforestation effect.
Existing roof waterproof generally adopts pea gravel concreten as rigidity water-proofing material, and this rigidity water-proofing material ftractures because of expanding with heat and contract with cold easily, causes roof leakage.Disclose among the Chinese patent CN1J064515A a kind of on roof panel and insulation layer, adopt bilayer to stagger to gather in wire gauze and the cement mortar rub into glass fiber life job practices, prevent that waterproofing course from cracking, reach the purpose of waterproof.Though this job practices has the better waterproof energy, construction is complicated, the cost height, and because of having adopted heat insulating material, and make indoor summer sultry, be unsuitable for promoting the use of in south.
The object of the invention is to provide a kind of easy construction, and is cheap, the green leakage-proof roofing of good leak-proof effect.
The present invention lays one deck waterproofing course on existing roofing leveling layer, the earthwork or sand filling out on the waterproofing course more than the 5cm are provided with barricade around the earthwork or sand, and the barricade below is provided with drain hole.
In the roofing earthwork of the present invention's design, can plant grass, plant vegetables, plant small-sized fruit tree, form the roof garden, this will produce profound significance concerning the day by day rare modern city in soil, for afforesting and beautifying environment, keeping ecological balance, promote the recurrence of the Nature, played positive effect.
The roof leakage performance of the present invention design is good, and it is simple and convenient construct, and cost is low, and can make full use of the modern city space, afforests and beautifies environment, and the minimizing municipal pollution is the national economy service, for the mankind benefit.
In order to make roof structure of the present invention clear more complete, enumerate embodiment below, and be described further in conjunction with the accompanying drawings.
Fig. 1 is a cross-sectional view of the present invention.
Fig. 2 is the structural representation of waterproofing course embodiment one of the present invention.
Fig. 3 is the structural representation of waterproofing course embodiment two of the present invention.
Fig. 4 is the structural representation of waterproofing course embodiment three of the present invention.
Among the figure: 1 is roofing, and 2 is leveling layer, and 3 is water-repellent paint, and 4 is waterproof roll, and 5 is water-repellent paint, and 6 is water-repellent paint, and 7 is barricade, and 8 is the earthwork or sand, and 9 is waterproofing course, and 10 is drain hole.
As shown in Figure 1, the present invention lays one deck waterproofing course 9 on the leveling layer 2 of existing roofing 1, and the earthwork or sand 8 filling out on the waterproofing course 9 more than the high 5cm are provided with barricade 7 around the earthwork or sand 8, be provided with drain hole 10 below barricade 7.
In like manner, (also the claiming gutter) part of cornicing also can adopt structure same as described above.
Structure embodiment such as the Fig. 2 of waterproofing course 9 among the present invention--shown in Figure 4.
Embodiment one
As shown in Figure 2, waterproofing course 9 structures that present embodiment adopted are: water-repellent paint 3+ one deck waterproof roll 4 (or plastic sheeting)+water-repellent paints 6.That is,, on this water-repellent paint 3, paste one deck waterproof roll 4 or plastic sheeting at coating one deck on the leveling layer 2 of roofing 1 has viscosity under cold-working industry or hot work condition water-repellent paint 3 (abbreviation water-repellent paint); The bonding method of this layer waterproof roll 4 is: flow overlapping successively spreading out (as shown in the figure from top to bottom downstream along roofing, be that the lastblock waterproof roll is positioned at the top of next piece waterproof roll), overlapping width is more than the 10cm, and at overlapping with water-repellent paint or adhesive plaster 5 adhesions, on waterproof roll 4 or plastic sheeting, be coated with one deck water-repellent paint 6 again, constitute waterproofing course thus.Construct the barricade 7 more than the high 5cm then at load bearing wall roofing position, about 1 meter 1 drain hole 10 is set at every interval below the barricade above the roofing 7.(being the top of water-repellent paint 6) inserts the earthwork or the sand 8 of high 5cm in barricade 7.
Embodiment two
As shown in Figure 3,4-1,4-2 is waterproof roll, and the structure of the waterproofing course 9 of embodiment 2 is: the two-layer waterproof roll of water-repellent paint 3+ (or plastic sheeting) 4+ water-repellent paint 6.That is, it is between water- repellent paint 3 and 6, lays two-layer waterproof roll.At two-layer waterproof roll 4-1, between 4-2 the coating or be not coated with water-repellent paint, other structure is identical with embodiment 1.
In like manner, at the waterproof roll that also can be provided with between water- repellent paint 3 and 6 more than two-layer.
Implement three
As shown in Figure 4, the structure of the waterproofing course 9 of embodiment 3 only is one deck: water-repellent paint.Promptly the water-repellent paint 3 more than the thick 3 μ m of coating on the leveling layer 2 of roofing constitutes waterproofing course of the present invention thus, and all the other are with embodiment 1.
Above-mentioned water-repellent paint can be pitch or various emulsion-type or solvent-type waterproofing paint.As reclaimed rubber-asphalt roofing water-repellent paint, JG-1 water-proof cold adhesive, JG-2 water-proof cold adhesive, elaterite water-repellent paint, chlorine J-1 water-repellent paint, chlorine J latex bitumen coating or the like.Above-mentioned waterproof roll can be various asphalt water-proof coiled materials (being malthoid) or synthetic materials coiled material, as sand face glass fiber blank malthoid, and paper tire petroleum asphalt felt, polyvinyl chloride (PVC) waterproof roll, vulcanization type rubber malthoid, Chlorinated polyethylene plastic sheets for waterproofing or the like.
