Abstract

The present invention provides one kind of structure for roof greening. One water draining and isolating and bearing sandwich layer is constructed between roof and greening layer can solve the problems associated to greening and roof leakage prevention. Roof greening can improve city environment, save power and low engineering cost.

Description

Roofing-greening soil retaining, draining, preserve moisture, the new technology of water proof, antiseepage

The present invention is a kind of structure method for designing of plantation greening on building coats, and particularly building roof, underground square surface layer, plantation need keep off the synthesis structure method that soil, draining prevent the building coats seepage again when afforesting.

Plantation greening on roofing at present has following several form: directly be deposited in earth on the roof; Perhaps, repave the geotextiles of retaining soil, mound kind greening on this at roofing upper berth cobble drainage blanket; And external geotextiles composite material profit is played effect of retaining soil, draining or the like in flower bed.Said method only can be planted greening, but roofing causes seepage easily.The inventor can dredge percolating water according to the overall clearance interlayer, eliminate the principle of water pressure, designed novel products " a kind of under building coats interstitial plastic formwork " and obtained patent ZL97234643.0 and " making the method for structure void interlayer with band fulcrum flat board " number of patent application 99113840.6, principle can solve the synthesis structure problem of roof greening in view of the above.

Purpose of the present invention is to lay the overall clearance sandwich slab on roofing, can the white-out rainwater, make the roofing leakproof, and also have the retaining moisture preserving function in the void layer.

The object of the present invention is achieved like this, and through thermoplastic shaping, becoming has the medicine for treating uneven of pressure-bearing fulcrum to pull with plastic sheet, and dull and stereotyped edge fulcrum can overlap superimposed mutually.Earlier plastic plate completely is layered on the roofing, on plastic plate, completely spreads geotextiles again, have between making roofing and afforesting can pressure-bearing the space interlayer.Can build flower bed mound kind tree above the geotextiles, the mortar that the lays cement face of building or paving a road, and plant the lawn.The plastic plate of band fulcrum mainly contains following several respects effect:

1, pressure-bearing (compressive strength＞30T/M ²),

2, become the water barrier of roofing behind the whole overlap joint,

3, form the drainage space layer between fulcrum and the geotextiles,

4, the space that has retaining to preserve moisture between the fulcrum,

5 and roofing between also reserved the space interlayer that can arrange percolating water.

When the inventive method is applied to roof greening, can alleviate load, solved planting technique, comprehensive technical problems such as roof antiseepage.Roof greening can provide activity space for the resident, is energy-saving building, has also improved civic landscape, has improved urban ecological environment quality.This method can be applied to the antiseepage of new construction and old roof and administer, and can save the heat insulating material of conventional roofing, and the waterproofing materials of saving 2/3, has both reduced construction costs, has improved service property (quality) again.

Further set forth concrete enforcement of the present invention below in conjunction with accompanying drawing:

Fig. 1 is the floor map of band fulcrum flat board of the present invention;

Fig. 2 is the A-A generalized section of Fig. 1 product between roofing and geotextiles;

Fig. 3 is the roofing flower bed, the overall schematic on macadam pavement, lawn;

Fig. 4 is the node schematic diagram in flower bed peripheral hardware gutter;

Fig. 5 is the node schematic diagram of vertical drain gully.

Example 1, schematic diagram of the present invention

See that from Fig. 1 floor map pressure-bearing fulcrum 1 is arranged, stiffening rib 2 and following pressure-bearing fulcrum 3.On Fig. 2 generalized section, form draining between fulcrum 1 and the geotextiles 4, ventilative void layer 6 surrounds water storage space between stiffening rib 2 and the fulcrum 3, stiffening rib 2 and roofing and between formed white-out percolating water void layer 5.Example 2, the organigram of the present invention and the face of use

Fig. 3 is the geotextiles 4 at the space interlayer, builds flower bed 8 above, paves 9, plants lawn 10, and the water yield of roofing can both be discharged from the drainage blanket 6 that connects.Fig. 4 is that flower bed is built to reserve drain hole and gutter 11 on roofing, and plastic plate discharges flowing water reserving borehole hole, position, water hole 12 from the hole, and periphery turns over geotextiles that into plastic plate is fixing with steel nail 13.Fig. 5 is a plastic plate through vertical drain gully, cuts hole 15, geotextiles 4 whole topped past from the escutcheon that falls into water.

Claims

1, roof greening, retaining soil, draining, preserve moisture, the new technology of water proof, antiseepage, be to adopt overall clearance interlayer principle to solve the technical measures of roof greening workmanship, it is characterized in that: roofing with afforest between have can pressure-bearing, the space interlayer of draining, water proof.

2, the method for claim 1 is characterized in that: the space that the space interlayer has retaining to preserve moisture under drainage blanket.

3, the method for claim 1 is characterized in that: superimposed mutually or overlap joint becomes water barrier with band fulcrum plastic plate.

4, must ask in the 3 described methods as power, it is characterized in that: between water barrier and roofing the space be arranged, can draw percolating water, eliminate the roofing seepage pressure.

5, in the method for claim 1, it is characterized in that: on the geotextiles of roofing space interlayer, can the mound kind afforest, or making pedestrian road surface.

6, in the method for claim 1, it is characterized in that: will be with the superimposed or full shop of overlap joint of fulcrum plastic plate during construction earlier; Completely spread geotextiles again, the superimposed joint of the employing of geotextiles becomes integral body.

7, in the method for claim 1, it is characterized in that: the delivery port of space interlayer will make the percolating water under the hydrophobic and plastic plate on the plastic running surface unobstructedly discharge.
