Abstract
A construction method for the water-proof and damp-proof layer of roof or floor or wall features that the levelling layer, water-proof and damp-proof sand layer, isolating layer, protecting layer and reinforcing decorative layer are sequentially spreaded. Said water-proof and damp-proof sand layer is the mixture of sand, asphalt and wax. Its advantages are simple and feasible method, no environmental pollution, high resistance to water, high temp. acid, alkali, ageing, low temp and ultraviolet radiation.
Description
The present invention relates to the job practices of a kind of roofing, ground waterproof, damp-proof course.
Roof leakage, ground humidity are troubling problems always.The tradition roof waterproof adopts ointment, malthoid, pitch flexible web, and their long term exposure are under solar radiation, and easily aging, easily be full of cracks, waterproof and thermal insulation property are poor, and must must overhaul every several years.Publication number is that the water-proof, moisture-proof insulating material of " a kind of particle type water-proof, heat preserving and insulating material and method thereof " class of 1163247 exists that construction is difficultly grasped, the softening caking of paraffin layer under the high temperature, can burst with building knot material and open and leak.These materials all only are used in roofing in addition.
The applicant has applied for " a kind of production method of waterproof and moistureproof heat insulating sand " (application number 99116552.7), and its product is through check, its concrete main performance index such as following table.
| Outward appearance | Loose light yellow particle, no earth foreign material, contain a small amount of powder |
| Fineness | 2.5mm the hole sizer surplus is 0 |
| Unit weight | ??1300-1400kg/m |
| Moisture content | ??≤1％ |
| Impermeability | Hydrostatic pressing 80mm water column, 72h are waterproof |
| Heat resistance | 80 ℃ ± 3 ℃ temperature, 8h is waterproof |
| Acid resistance | The waterproof C of 3%HCL solution 50h |
| Alkali resistance | The waterproof C of saturated Ca (OH) solution 50h |
| Ageing-resistant | Waterproof behind 75W ultraviolet lamp, height 40mm, the irradiation 200h |
| Frost resistance | -30 ℃ do not influence the product physicochemical property |
| Coefficient of thermal conductivity | ??0.15-0.30W/(m.k) |
Purpose of the present invention aims to provide the job practices of a kind of roofing, ground waterproof, damp-proof course, method is simple, cost is low, pollution-free, waterproof, the damp-proof course of construction have good impermeability, heat-resisting, sour, alkaline, anti-aging, low temperature resistivity and ultraviolet radiation resisting.
The implementation of the object of the invention is: the job practices of roofing, ground waterproof, damp-proof course, and construction follows these steps to carry out:
1) cleaning roofing 1, ground 7 comprise the roofing cementation of fissures, ground compacting,
2) lay the thick leveling layer 2 of 10-30mm with 1: 3 cement mortar,
3) lay thick waterproof, the moistureproof layer of sand 4 of 12-30mm,
4) lay separation layer 5,
5) thick pea gravel concreten or the cement mortar protective course 6 of cast 25-50mm, topping is provided with the lattice seam.
Waterproof, moistureproof layer of sand 4 be with husky, sand base-material and pitch or pitch, wax mix semiproduct A and fine sand base-material and pitch, wax mix semiproduct B, stir evenly the full loose type shot-like particle of gained by 60-85%A and 15-40%B, be layered on the leveling layer 2, strickling, compacting must not be leaked the shop.
During construction, waterproof, damp-proof course 4 are constructed synchronously with separation layer 5, topping 6, spread separation layer 5, topping 6 immediately after layer of sand strickling, the compacting.Separation layer adopts kraft or nonwoven, and every cloth or paper should overlap, and lap width is not less than 50mm.
The present invention is described in detail in detail with reference to the accompanying drawings.
Fig. 1 is by the non-accessible roof waterproofing course of the present invention's construction
Fig. 2 is by the accessible roof waterproofing course of the present invention's construction
Fig. 3 is by the floor damp-proof course it (1) of the present invention's construction
Fig. 4 is by the floor damp-proof course they (2) of the present invention's construction
Fig. 5 is by the floor damp-proof course they (3) of the present invention's construction
Fig. 6 is by the floor damp-proof course they (4) of the present invention's construction
With reference to Fig. 1, to the roofing of people's walking on the need, at the topping 6 upper berth clinker tiles of roofing 1, the walking layer 7 of concrete block class, brick, interblock are answered the cementation of fissures.
Require differently according to ground, on the cement mortar protective course 6 on ground 8, can make Fig. 3,4,5,6 multi-form ground.
With reference to Fig. 3, the thick thick cement sand bed 9 of concrete cushion 8.15-25mm of cast 50-120mm on cement mortar protective course 6.On cement sand bed 9, can spread the white stone polishing of 1: 2 thick cement of 15mm waxing surface layer 10 (see figure 4)s.Or on cement sand bed 9, paste the thick ointment of 3mm and glue 11, refill hardwood flooring layer 12 (see figure 5).
With reference to Fig. 6, the thick thick pea gravel concreten layer 12 of concrete cushion 8,30-40mm of cast 50-120mm on the cement mortar protective course 6 on ground 8.
The present invention adopts cement mortar, C15 concrete and the C20 pea gravel concreten material of 1: 2 or 1: 3.
Existing roofing, construction method of ground are all adopted in the present invention's other construction except that waterproof, damp-proof course, and the waterproof and moistureproof heat insulating sand that constitutes waterproof, damp-proof course only need be layered on the leveling layer, wipes compacting again off, job practices is simple, cost is low, to constructor and environmental nonpollution.
With waterproof, the damp-proof course of the inventive method construction, long service life, waterproof wherein, moistureproof layer of sand can reach more than 50 years application life.Waterproof, moistureproof roofing, ground with the inventive method construction have good impermeability, heat-resisting, sour, alkaline, anti-aging, low temperature resistivity and ultraviolet radiation resisting., can effectively prevent roof leakage and intercept the ground humidity by the inventive method construction on roofing, ground.
