Summary of the invention
The utility model provides a kind of inversion type haydite concrete planted roof, satisfies the comprehensive function requirements such as roof waterproof, energy-conservation, sound insulation, greening.
Realize with following technical scheme during the utility model: a kind of inversion type haydite concrete planted roof, its structure forms bottom-up being followed successively by: floor bearing structure layer, leveling layer, SBS waterproofing course, haydite concrete waterproofing course, the water-proof heat-preserving integrated material of hard-foam polyurethane, root-resistant puncturing separation layer, drainage blanket, filtration beds, plantation layer and vegetable layer.
The water-proof heat-preserving integrated material of haydite concrete waterproofing course and hard-foam polyurethane forms insulation layer in the said structure; The water-proof heat-preserving integrated material of haydite concrete waterproofing course and hard-foam polyurethane cooperates the waterproofing course that consists of the multiple tracks waterproof with SBS waterproofing course, root-resistant puncturing separation layer again.
Described roofing floor slab structure layer is cast-in-situ reinforced concrete slab, satisfies to comprise the structural bearing capacity design of planting load.
Described haydite concrete waterproofing course is the porcelain granule light weight aggregate concrete;
Described root-resistant puncturing separation layer is the polyvinyl chloride plastic film separation layer;
Described drainage blanket plastics lug drainage blanket, salient point is upwards arranged;
Described filtration beds adopts geotechnological filter cloth;
Described plantation layer is for being laid on the planting soil of the thick 200-400mm above the filtration beds.
The beneficial effects of the utility model are: adopt multiple tracks waterproof scheme; solve the waterproof problem of planted roof; adopt the lightweight aggregate haydite concrete; the problems such as load, waterproof, heat preservation and soundproof and the anti-grass roots of solution roofing pierces through; waterproof coiled material is placed inversion type scheme under the insulation layer, be convenient to waterproof and construction.The planted roof that provides, waterproof thermal-insulated, low-carbon energy-saving, green attractive in appearance, economical and practical, good endurance, significant in the popularization of Xia Redong cool region for the planted roof technology.

The specific embodiment
Below in conjunction with drawings and Examples inversion type haydite concrete planted roof is further described in detail.
As shown in Figure 1, its structure of inversion type haydite concrete planted roof forms bottom-up being followed successively by: floor bearing structure layer 1, leveling layer 2, SBS waterproofing course 3, haydite concrete waterproofing course 4, the water-proof heat-preserving integrated material 5 of hard-foam polyurethane, root-resistant puncturing separation layer 6, drainage blanket 7, filtration beds 8, plantation layer 9 and vegetable layer 10.
Floor bearing structure layer 1 is the cast-in-situ steel reinforced concrete roof panel, and thickness is determined according to structure design at 160-200mm.
Leveling layer 2 is the thick mortar of 20mm, and planeness satisfies the construction requirement of waterproof coiled material.
The thickness of the water-proof heat-preserving integrated material 5 of hard-foam polyurethane is 50mm; Haydite concrete waterproofing course 4 is that thickness is the thick porcelain granule light weight aggregate concrete of 40mm; The water-proof heat-preserving integrated material 5 of haydite concrete waterproofing course 4 and hard-foam polyurethane forms insulation layer.The porcelain granule light weight aggregate concrete adopt particle diameter be the 5-20mm haydite as aggregate, adopt the method configuration of prewetting, strength grade is C25, apparent density is 1756kg/m
3, slump is 160mm, has good workability, and concrete permeability resistance meets the requirements, and the porcelain granule light weight aggregate concrete of configuration has the function of waterproof and insulation, constructs simple and practical.Haydite concrete is built and is adopted secondary to smear compression technology, guarantees that haydite concrete is built face smooth and closely knit.The porcelain granule light weight aggregate concrete base layer should be smooth, dry and clean, the waterproof and insulation integrated material of spraying hard-foam polyurethane, and proportioning is answered accurate-metering, the foaming even thickness is consistent, construction environment temperature is preferably 15~30 ℃, and wind-force should not be greater than three grades, and relative air humidity should be less than 85%.
Root-resistant puncturing separation layer 6 is the thick polyvinyl chloride plastic film separation layer of 4mm; Installation of membrane should meet the requirement of synthetic polymeric waterproofing material construction with cold alhesion method, and the lap width of long limit and minor face all should be less than 100mm, and the overlap joint sealing is used the compatible encapsulant of wood property and obturaged.
Drainage blanket 7 adopts the high plastics lug of 20mm drainage blanket, and salient point is upwards arranged; Plastic row (holding) water plate adopts the splicing processes construction, and lap width should be less than 100mm.
Filtration beds 8 adopts 200g/m
2Geotechnique's filter cloth; Take to overlap the method construction of dried shop.Filtration beds is set to preventing that planting soil from entering drainage blanket and causing loss to play an important role, the selection of filtration beds should not be too thick, also should not be too thin, so that draining and prevention soil erosion and obstruction are principle.
Plantation layer 9 is for being laid on the thick planting soil of 200-400mm above the filtration beds 8.Plantation soil layer 9 is selected the conditioned soil of the configurations such as humus soil, vermiculite, the peat composed of rotten mosses, soil layer unit weight 8kN/m
3-10 kN/m
3Adopt conditioned soil, can reduce density of soil, reduce load, soil is convenient to disinfect, and is beneficial to vegetation growth.
Leveling layer 2 is the thick mortar of 20mm, and planeness satisfies the construction requirement of waterproof coiled material.
Deck 1 is the thick situ Concrete Slabs of 160-200mm, determines according to structure design.
The thick polyvinyl chloride plastic film separation layer 6 of above-mentioned 4mm, 50mm hard-foam polyurethane waterproofing course 5,40mm porcelain granule light weight aggregate Concrete Anti water layer consist of 4 and 2 layers of SBS coil waterproof layer 3 and consist of waterproofing course.
Vegetable layer 10 is planted as required.
