Waterproof and heat-insulation structure of planting top plate

Abstract

The invention provides a waterproof and heat-insulation structure of a planting top plate. The waterproof and heat-insulation structure sequentially comprises a waterproof steel reinforced concrete top plate, a second cement mortar leveling layer, a common waterproof layer, a heat-insulation layer, a first cement mortar leveling layer, a root resistance coiled material waterproof layer, an isolation layer, a C20 fine stone concrete protection layer, a concave-convex water drainage plate or water storage plate, a filtering layer, planting soil and a vegetation layer from bottom to top, wherein the root resistance coiled material waterproof layer is a root resistance coiled material; and the common waterproof layer is one out of a high-grade composite D-type self-adhered waterproof coiled material with the thickness of not smaller than 2.0mm, a double-layered high density polyethylene laminated composite self-adhered waterproof coiled material with the thickness which is not smaller than 1.5mm and a composite macromolecular self-adhered waterproof coiled material with the thickness of smaller than 1.5mm. With the adoption of the structure provided by the invention, the waterproof effect is guaranteed and the service life is prolonged; the heat-insulation effect is good and water does not leak; and the construction period is greatly shortened and the structure is suitable for the growth of vegetation.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a waterproof and thermal insulation structure of a planting roof. Background technique [0002] The planted roof structure is conducive to adjusting the indoor temperature, alleviating the urban "heat island effect", absorbing harmful substances, improving urban air quality, and at the same time improving the ecological living environment of the city to achieve coordination and common development with the environment. Therefore, it meets the requirements of realizing sustainable development vigorously advocated by the state, is conducive to the construction of a resource-saving and environment-friendly society, and also reflects people's requirements for an ecological living environment. However, if the design of the planting roof is not reasonable enough, it will easily lead to water leakage on the roof, which will increase the cost of the project. At the same tim...

Problems solved by technology

However, the current ecological roof structure mainly uses a box-type structure. Although it plays a role in beautifying the environment, its impact on waterproofing and structure is not very ideal, and it is not a part of the building structure layer.

Moreover, the existing technology used for the interface protection layer of conventional waterproof membranes includes
