Abstract

An overhead greening scheme relates to two-area of making city green in three-dimensional and the construction reform on even roof of building. With building root being rebuilt orderly till preventing from leakage for relative long time, the goal to construct the natural plant on air can be attained. The central contents include changing the sloping roof into even roof, taking out rainspout and thermal insulation layer. Plant can be grew with soil or without soil after completing the waterproof on the construction layer, meanwhile, the assistant irrigating facilities need to be added.

Description

Aerial greening scheme

Aerial greening scheme relates to afforestation of city and two fields of building roofing structure of modification, be intended to by to after building roofing structure and the order reform, make it to reach building roofing effect of seepage anything but in the long term, utilize the natural greening in roofing space, solve the contradiction that afforestation of city and ground installation are striven the region, open up the space resources of city afforestation sustainable development, also can prolong roofing antiseepage function service interval simultaneously, reduce the building repair cost.

The greening work in city is always carried out on ground, expansion along with the modern city building size, the ratio cumulative year after year of infrastructure and house exploitation land occupation, relatively, the ratio of afforestation of city land occupation reduces year by year, use the contradiction in soil to become increasingly conspicuous, form the result of above-mentioned contrast phenomenon, giving scientifically plans a city builds general layout formation obstacle.The reduction of greening ratio, the hysteresis of greening work makes the natural consumption situation of nitrogen oxide in the atmosphere be difficult to reach the requirement of the index of environmental protection, directly affects the healthy of townsfolk.Traditional physical construction planning scheme can not satisfy the demand in epoch far away.So-called hanging garden, main dependence is provided with potted landscape and decorates the roofing balcony, and permanently aerial natively greenery patches, hanging garden are still as mirage.Rely on ground and do afforestation of city, mainly have following defective:

One, the greenery patches ratio is little.

Two, land utilization ratio is low.

Three, greening work and infrastructure construction land used are particularly thorny.

Utilize building roofing to implement vertical planting, at first must solve roof leakaging problem, traditional roof structure and order cause roofing to be difficult to overcome the defect of seepage, and its main crux is:

One, the mistaken ideas of Design Thinking: the designer at first considers drainage problem in the design roofing, under Design Thinking is dominated mistakenly, a series of structure situation (as flashing slope, leader etc.) that causes the building roofing seepage occurred.

Two, sequential organization is unreasonable: waterproofing course is located on the insulation layer, is difficult to overcome the defective that causes waterproofing course, leveling layer fracture because of the inhomogeneous slump of insulation layer.

Three, typically cause leakage drawback: around the leader, be that the typically multiple material interface in a place (as cast iron, plastics, mortar or concrete and waterproofing materials, heat insulating material etc.) is because various materials at normal temperatures on building, the difference of its weatherability and harmomegathus rate causes the regular seepage in this position.

Four, leakage cause routinely: most roof waterproof layers adopt and expose construction, and most of waterproofing materials weatherabilities are poor, aging easily embrittlement, and the waterproofing course of exposure has shortened the life cycle of waterproofing materials widely.

The traditional greening mode and the disadvantage of roof structure form have below been set forth briefly respectively.Below designer's thinking characteristic just, how roof structure is transform as embodiment, be further elaborated.

Embodiment: figure one is the roof structure sectional drawing of conventional design; Figure two is improved roof structure sectional drawings.

Roof structure and order reform scheme:

One, leveling off top flashing domatic roofing is horizontal roofing.

Two, remove leader (flat pattern is in roofing or perpendicular to roofing), can more than the roofing Horizon, suitably highly be parallel to roofing weep pipe is set, so that under the saturated situation of natural rainwater, unnecessary water is discharged by weep pipe.

Three, on the deck after levelling direct shop house waterproofing course, avoid the waterproofing course gene basis to subside and chap, waterproofing course is located at latent worn-out position, can avoid being subjected to ultraviolet direct projection, is subjected to the bromine oxygen corrosion aging.

Four, remove insulation layer.Insulation layer can be by soil and vegetation substitute naturally.

Five, set up the unconcerned reservoir bed of bubble, set up the supplemental irrigation facility.

The above-mentioned basic scheme of understanding in brief the roof structure transformation, those skilled in the art has had preliminary understanding to designer's intention, from more than the deck,, embodiment at all levels and requirement are further described again below with two target orders of figure.

One, deck: with the garden orifice plate is the aspect of deck, must make waterproof reinforced to plate seam, the inner corner trim of garden orifice plate and handle; With big plate or Cast-in-place concrete is deck, must make waterproof reinforced to its inner corner trim and handle.The method of handling is implemented according to norm of construction.The processing quality of this one deck is very important, and it is the basis of whole roofing no seepage and no leakage.

Two, leveling layer: the standard levelling, finished product is horizontal roof.

Three, waterproofing course: select the adhesive property height for use, the product specification shop house that impermeability is good, (other material also can be used) finished product acceptance method is pressed code requirement.Preferably after the 200mm hydrostatic test 48 hours is water-tight, can carry out next procedure.

Four, reservoir bed: but shop house hard steeps unconcerned plastics, sponge or other water-absorbing material, also can give up with the discarded object shop of equal quality.

Five, supplemental irrigation facility: shop house supplemental irrigation facility (as infiltrating irrigation, drip irrigation or sprinkling irrigation etc.), in order to save water resource, water or directly use sewage during irrigation water can be used.

Six, native naturally: shop house nature soil.According to the different situations of roofing load and vegetable layer kind, also can directly do soilless culture.

Seven, vegetable layer: according to different needs, can plant flowers and plants, vegetable melon and fruit, dwarf trees, also can build aerial amusement and recreation place.

More than merge argumentation, but, be not restricted to the foregoing description at aspects such as construction, selection, finished product appearance and purposes as embodiment.

By the transformation of the way to roof structure, for the greening work in city is provided with the space resources widely of a sustainable development, the enforcement of this programme, can bring following social benefit valuably and economic benefit:

One, realizes vertical planting, increase green coverage.

Two, make building reach non-leakage purpose of long term, reduce repair cost.

Three, improved the heat-insulating property of building.

Four, the utilization rate and the gold content of building have been improved.

Five, opened up development space for city tour and amusement and recreation place.

Six, make building possess certain strategic protective effect.

Seven, improve the natural conversion ratio of nitrogen oxide in the atmosphere, reduced atmospheric pollution level, ensured health.

Of particular note, according to the inventor's Thinking Characteristics, those skilled in the art also can make various equivalences or non-equivalent substitution in each link, and these all should be included within the technical scope of the present invention.

Claims

1, a kind of method of urban three-dimensional green enforcement.By to after the type roofing transformation of the way of flat-top flashing slope, make it to become horizontal roofing, utilize roofing to build aerial natural vegetation, also tourism or leisure, body-building, public place of entertainment can be set.
