Abstract
The utility model provides a light planting roof which successively arranges a heat insulation layer, a water storage layer, a hydrophobic layer, an insulation layer, a growth bed and a planting layer on the waterproof roof of traditional II reinforced concrete. The heat insulation layer is made of polystyrene or polyethylene foam thermal insulation plate. The water storage layer is a mixed layer of gravels and sands. The hydrophobic layer is a gravel layer, the insulation layer is non-woven fabric, the growth bed is a stroma layer for cultivation and the planting layer is stonecrop. In the case of rain, the utility model allows the rainwater to go through the growth bed and the insulation layer and discharge a large amount of water in the hydrophobic layer and take out a large amount of heat through the water evaporation at the water storage layer, the growth bed and the planting layer. The utility can maintain a low indoor temperature of the building top houses and effectively prevent the increase of the temperature of the roof thus to achieve the 'trinity' purpose of greening, heat insulation and waterproof. The light planting roof with the advantage of easy construction and low construction price can be widely used in the roof greenery project in southern newly built buildings and existing buildings.
Description
Technical field
The utility model relates to building roof, and particularly a kind of light-duty planted roof can be applicable to newly-built and the greening of existing building light roof.
Background technology
Roof greening has many-sided comprehensive function.It is the air-conditioning of building, can make building cool in summer and warm in winter; The protection roof structure prolongs roofing application life; Reduce heat island effect, improve the microclimate environment of building; And recreational functions etc.
At present the roof greening mode is mainly divided three kinds: the one, and weak at bearing capacity, do not have the light roof of Greening Design in advance, adopt " blanket type " greening of the intensive plantation of grass seeds that is fit to a small amount of planting soil growth.The 2nd, at " garden type " greening of the stronger roof planting shrub seeds of bearing capacity, but this roof greening requires roofing to have stronger bearing capacity, generally is not suitable for the roofing of having built.The 3rd, " combined type ", mainly on the roof four jiaos and load bearing wall limit with cylinder plant, potted plant mode arranges roof greening, this roof greening effect is relatively poor.For above-mentioned first kind of light roof, generally just on roof waterproof layer, do drainage blanket earlier, fill out 30 centimetres of plantation soil species grass that the left and right sides is thick again, the effect of heat insulation and the antiseep of this roofing all have problems.
The utility model content
The purpose of this utility model is to address the above problem, and provides a kind of heat insulation, not only can be used for new building but also can be used for the light-duty planted roof of existing building of antiseep.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of light-duty planted roof on conventional I I grade reinforcing steel concrete water-proof roofing, is provided with isolation layer, aquifer, drainage blanket, separation layer, growth bed and plantation layer successively.
Described isolation layer is polystyrene or polyethylene warming plate, and density is greater than 18kg/m
3
Described aquifer is gravel and husky mixed layer, and thickness is 15～25mm, is provided with outfall.
Described drainage blanket is a layer of gravel, and thickness is 5～15mm, is provided with outfall.
Described separation layer is a nonwoven, and permeability rate is greater than 65%.
Described growth bed be the cultivation matrix layer, thickness is 30～50mm.Cultivation matrix comprises peat, wood chip, vermiculite, haydite, float stone etc.
Described plantation layer is a stonecrop, and plantation density is 80～200 strains/m
2, become the plant height degree at 10～20cm.Stonecrop (Sedum lineare) another name manystem stonecrop leaf, heterophyll Drymoglossum etc. belong to the Crassulaceae herbaceos perennial.Stonecrop is used for the following good characteristics of light-duty roof greening tool: (1) drought tolerance is good, and vitality is strong, has the extraordinary characteristic that prevents water evaporates, and plantation is evergreen throughout the year in south.(2) extensive management, honesty attractive in appearance, stonecrop seldom needs management after the garden of covering with into (about 1-3 month).(3) coverage scale height, oxygen-supplying amount is big.
Adopt the engineering construction of this light-duty plantation roof structure to be: on the basis of conventional I I grade reinforcing steel concrete roof, to lay polystyrene or polyethylene warming plate, by the gravel and the sand of ratio blending in 1: 1, re-lay gravel, at drainage blanket and the aquifer mouth of a river that all begins to rehearse, spread nonwoven and cultivation matrix layer then, plant stonecrop at last.
Adopt this light-duty plantation roof structure, during rainfall, rainwater is discharged a large amount of water yields by growth bed, separation layer at drainage blanket; When rainfall stops, under the irradiation of sunlight, along with each techonosphere temperature raises, savings at first evaporates at the rainwater of grown layer, and the rainwater of putting aside simultaneously in aquifer also slowly is penetrated in the growth bed cultivation matrix, and goes out by growth bed evaporation.Because the evaporation of moisture can be taken away a large amount of heats, so can keep lower interior temperature, has stoped the rising of roof temperature effectively, reached purpose heat insulation and the protection waterproofing course.
The light-duty planted roof of the utility model is compared with present planted roof has following advantage:
(1) thermal isolation is effective, energy conservation.When summer temperature during at 30 ℃, exposed roof surface temperature can reach 40～50 ℃, and the plantation stonecrop can make the roof surface temperature reduce by 6～8 ℃, and the architectural top interior temperature can reduce by 3～5 ℃.Adopt this greening roof, can save building energy consumption about 30%.
(2) workable.This light-duty plantation roof structure is constructed on the basis of existing roof waterproof structure, and operability is simple, and technical difficulty is low, makes things convenient for the field worker construction.
(3) applied widely.This light-duty plantation roof structure is not only applicable to new building, also is widely used in the roof greening of existing building.
(4) building material wide material sources, abundance.Each techonosphere material can be realized localization, and resource is extensive, sufficient, does not design the techonosphere material of special fabrication processes.
(5) cost performance is reasonable.This light-duty plantation roof structure comprehensive cost is lower, heat insulation, insulation, waterproof effect stable performance, and is reliable, can be that most of residents accept.
