Description

A kind of integration product and construction method of New Roof greening

Technical field

The invention belongs to building fields, and in particular to a kind of product for roof greening.

Background technique

Roof greening be construct the environment that can be suitble to plant growth using top of building as place, then plant lawn, The plants such as flowers, to build a kind of with garden landscape ecological environment form.Roof greening is in limited city space Ratio of green space most effective way is improved, can be conducive to change aerial landscape, embodies modern big city elegance；Be conducive to protection life State, purification air, Shad density, reduction room temperature, noise and urban heat land effect, environmental benefit are huge.So it is green to develop roof Change has very wide prospect, and invention and popularization matching technique for roof greening are also that thing must go.But existing roof greening is more It is that traditional hardness is taken to imitate ground planting patterns, Anti-seeping technology is done to roof with engineering means first, is filled out later on roof The soil planting plants of upper 200-400mm thickness, such method, project amount is big, and investment is big, and aggravates the load of roofing, causes The beam slab arrangement of reinforcement of various roofing top plates or the increase of structure, whole gravity are easily more than that the load on roof generates all the building Harm, and the later period daily manages and protects difficulty, it is difficult to it is universal, it is difficult to generate big ecological benefits.

Summary of the invention

The present invention can be manufactured on a large scale using industrial production means, for the integration product of roof greening, mainly Feature is that vegetable seeds, growth substrate and antiseepage root resistance Material cladding are formed the volume that can be directly used for roofing Shape or band-type product have the advantages that speed of application is not limited by roof condition fastly, can be used for the greening on various roofs.This hair It is bright to belong to light-duty roof greening material, suitable growing environment can be provided for roof greening plant, it can be to former roof knot Installed and used under the premise of structure is without any changes, have it is light-weight, it is structurally reasonable, securely and reliably, installation, convenient disassembly, make The advantages that valence is low, wide adaptability, easily universal.

The present invention provides a kind of integration product of New Roof greening.This has multilayer degradable function structure, is one The roof greening light composite structure that kind structure is simple, load load-bearing is small and afforestation effect is good, the present invention, which has, to be retained, fertilizer conservation, The features such as stability is good and plant easy planting.
