Large-space saddle-shaped overall greening roof system

Abstract

The invention discloses a large-space saddle-shaped overall greening roof system. The large-space saddle-shaped overall greening roof system comprises a saddle-shaped reinforced concrete thin-shell structure panel with grid-type reversed beam ribs and a roof greening plantation construction, wherein the saddle-shaped reinforced concrete thin-shell structure panel with the grid-type reversed beam ribs comprises a saddle-shaped shell plate and the grid-type reversed beam ribs which are convexly arranged on the upper surface of the shell plate; the shell plate is a standard single-piece doubly-inclined hyperbolic paraboloid torsional shell; an edge beam is arranged at the edge of the shell plate; the shell plate and the grid-type reversed beam ribs are reinforced in a unified manner and are formed by synchronous overall type pouring; the roof greening plantation construction consists of a waterproof layer, a root puncturing resistance layer, a protection layer, a water drainage layer, a water retention layer, a filter layer, a soil layer and a plant layer which sequentially covers the shell plate and the grid-type reversed beam ribs from bottom to top; a water seepage pipe is arranged on the protection layer along the edge of a plantation groove. According to the large-space saddle-shaped overall greening roof system, the conflict between a large-span space structure and a roof greening load is effectively overcome, and a roof system which is most ecological and energy-saving is created for a large-space building.

Description

technical field [0001] The invention relates to the field of building roofs, in particular to a large-space saddle-shaped integral green roof system. Background technique [0002] Roof greening, as an energy-saving design method that has gradually become known and practiced in China in recent years, is of great significance for reducing the urban heat island effect and maintaining a space environment that is warm in winter and cool in summer; a large-space building is a large-scale, complex structure, For densely populated buildings, the roof system is a key component of the enclosure structure. In the traditional sense, the requirement for a long-span space on the roof load is that the lighter the better, the roof covering soil can effectively achieve energy saving, but it is also The load burden of the roof structure is increased. Therefore, how to deal with the contradiction between the long-span space structure and the soil-covered roof load is the main problem considere...

Problems solved by technology

[0007] To sum up, the existing technical research includes the relatively mature construction technology of thin-shell structure and ribbed thin-shell structure, the construction technology of slope green roof, etc., but there is no systematic green roof design for large-space buildings. way, the present invention provides a method of organically integrating the thin shell structure with the roof greening structure, and through the innovative means of structural design, it can well solve the problems of complex anti-skid components and difficult maintenance and management of the roof greening
