Description
Technical field
The utility model relates to a kind of roof structure, particularly a kind of can be top of building making rooftops green crop, and there is the top of building eco-house roof construction of good waterproof, water saving, thermal and insulating performance.Belong to field of house buildings, be applicable to multilayer, high-rise building roof structure engineering, be specially adapted to green building roof structure engineering.
Background technology
Along with the raising in expanding economy and people's understanding, construction ecological residence, green housing cry grow to even greater heights.Ecological roof is not a kind ofly directly to be connected with soil, in the plantation of building top and the form of afforesting, is also the roofing processing form of a kind of novel energy-conserving and environment-protective, green building.It not only saves the ground, urban district of an inch of land is an inch of gold, form vertical planting, more can bring into play reduction interior temperature, reduce heat island effect, recycle rainwater, purify air, a series of functions such as energy conservation, what it was contained is not merely roof planting, also comprise balcony, balcony, balcony, the greening of the special space of all kinds of buildings that are not connected with ground natural soils such as overpass bridge and structure, that people are according to the ecological environmental condition on building roof structure feature and roof, the vegetable material of selecting habit to adapt with it, by certain skill, at building roof and all special spaces, construction has a kind of form of the green landscape of certain function.
The ecological roof of top of building, to increasing urban green space area, improves the environment for human survival space that city high rise building mansion stands in great numbers, increasingly worsens, and improves ecological effect, beautifying urban environment has great significance.During existing urban building is built, roof is substantially idle, and utilization ratio is low, and sometimes people can stack foreign material on roof, affect the aesthetics of getting a bird's eye view in city, and roof do not have object coverage, and solar radiation in the time of summer, makes temperature within doors very high.
For solving appeal problem, existing a kind of at present have good have waterproof, a noise-proofing, improves dwelling environment, reduces solar irradiation and insulation, heat insulation and eco-house roof construction that can cultivated plant.This eco-house roof construction sets gradually from top to bottom insulation layer, waterproofing course, separate activities layer in roof basic unit, every root layer, moisturizing blanket, draining aquifer, isolation filtration beds, hypothallus and vegetable layer.But the moisturizing blanket of this roof greening system is laid between root separation film and water-draining-and-storing slab, and the moistening effect of hypothallus top and the bottom is differed; In roof basic unit, except one deck waterproofing course, there is no other waterproof measure; Vegetation maintenance water supply volume is large, needs at set intervals maintenance, and hand labor power requires high.
In sum, although existing roof structure has been obtained good effect under suitable engineering specifications, also have some roof structures to consider green, energy-conservation requirement, but structure in roof waterproof, water-saving irrigation, prevent that the aspects such as planting soil loss from remaining certain shortcoming.Given this, needing at present invention badly, a kind of to meet roof green as growth requirement, has the ecological roof of top of building of the top of building eco-house roof construction of good waterproof, water saving, thermal and insulating performance.
