Tree planting and landing method for building roof greening and roof tree hole node structure of tree planting and landing method

Abstract

The invention discloses a tree planting and landing method for building roof greening and a roof tree hole node structure of the tree planting and landing method. A tree hole is formed in a building roof to enable a tree to be planted on the building ground, and a crown is exposed out of the roof to play an outdoor greening role. The method is characterized by establishing a composite structure suitable for diagonal intersection of a main structure net and a tree planting net, and the technical program comprises the following steps: a, arranging a functional grid and a functional unit; b, deducing a structural grid; c, importing tree planting grids which are diagonally intersected with the structural grids and preliminarily determining tree planting points; d, expanding the functional unit; e, determining a tree planting point, the tree hole and a tree pit according to the structural scheme; and f, technically designing a main body, a node and the like and determining a transplanting technical scheme and implementing the same. The roof tree hole node structure provided by the invention comprises a prefabricated sleeve, a rainproof cap, a water receiving ring disc and an overflow guide pipe. According to the invention, the current roof greening limitation is broken through on the basis of economy and rationality, the environmental value equivalent to the original soil green space and the ecological benefit are given, and thus a building and greening can be continuously blended.

Description

technical field [0001] The present invention relates to a tree planting method for building roof greening and its roof tree hole node structure, specifically the method and the roof for planting trees on the building ground by opening tree holes in the structure layer of the building roof, exposing the crown of the tree and playing the role of outdoor greening A tree hole node structure belongs to the technical field of architecture. Background technique [0002] In most civil construction projects in my country, there are norms or local rules and regulations on the green space rate. At the same time, taking the parking garage as an example, the expansion of building land in modern society must also meet the parking ratio index, which reduces the green space. The contradiction between building space requirements such as green land and parking space is becoming more and more prominent, and it is an inevitable choice to combine the two. [0003] For residential areas with high...

Problems solved by technology

[0010] In view of the deficiencies in the above-mentioned existing soil-covered arbor greening design practices and the contradiction between tree planting and structure in conventional parking garage structures, the present invention provides a tree planting and landing method for building roof greening and its roof tree hole node structure, which solves the problem of building roof greening. The main function structure and tree planting are reasonably integrated and arranged and the system realization of related technologies, and provide the key node structure, break through the growth limitation of trees on the roof covering soil layer of the vast overhead space, and give the covered green space equivalent to the environmental value of the original soil green space , while greatly reducing the thickness of the covering soil and the corresponding main structure load, simplifying the main waterproof and auxiliary equipment investment and operating costs
