Long-rooted plant planting structure in bearing wall at top of building and construction method

Abstract

The invention relates to a long-rooted plant planting structure in a bearing wall at the top of a building. A planting space with an opening is reserved in the outer-side wall of the bearing wall at the top of the building, wherein the section of the planting space takes the shape of a right trapezoid; the interior of the planting space is filled with a nutrient soil layer, and a long-rooted plant is planted in; thermal insulation layers, waterproof layers and root isolation film layers are arranged at the bottom and side walls of the planting space; well type drainage tanks, a perforated water storage plate, filtering geotextile and a filtering layer are sequentially arranged at the bottom of the planting space from the bottom up; a steel tie bar is pre-buried in the bearing wall at the planting space, and is connected with an added reinforcing steel bar inside the wall body; a hard partition board is pre-buried in the wall body at the lower part of the opening, and drip irrigation pipes are arranged on the inclined wall of the inner side of the wall body at the upper part of the opening. According to the invention, under the premise that the overall performance of the wall structure is not influenced, a plant planting structure on the external wall of a building is provided, and the structure has the advantages of simple structure, attractive appearance, favorable thermal insulation performance and water-saving irrigation on the plant. The invention further discloses a construction method for the long-rooted plant planting structure.

Description

technical field [0001] The invention relates to a plant planting structure on the outer wall of a building, in particular to a long-rooted plant planting structure in which a trapezoidal planting space is provided in the side wall of the load-bearing wall at the top of the building. The structure has good integrity and good anti-seepage, heat preservation and heat insulation properties, and can also realize self-irrigation of plants. It belongs to the field of construction engineering and is suitable for urban building greening design, building energy-saving design, green building design and other projects. Background technique [0002] With the development of technology, the quality requirements of the living environment are constantly improving. The organic combination of architectural technology and ornamental gardening provides a wide range of application prospects for wall greening; at the same time, with the advancement of urbanization, the area of ​​urban green space i...

AI Technical Summary

Problems solved by technology

[0008] Although the above-mentioned wall greening structure has achieved good greening effect under suitable engineering conditions, there are still some shortcomings, mainly reflected in: the woven nutrient solution cultivation structure is not easy to repair, and the nutrient solution is also easy to cause water up and down due to gravity. Uneven; no matter the size of the boxes corresponding to the box-type cultivation, the cultivation medium will face aging and corrosion problems after the plants grow for a period of time, and the cultivation medium needs to be completely replaced; the medium plate of the medium-plate cultivation is easy to disintegrate during use , it is more difficult for the epiphytic plants to move to the new medium plate

In addition, due to the small specific heat of concrete itself, it is prone to problems such as high temperature in summer and low temperature in winter, which leads to poor growth environment for plants planted on concrete walls, and unhealthy plant growth and even death are prone to occur.

[0009] To sum up, urban three-dimensional greening has good development prospects. Most of the plants in the existing wall greening structure are separated from the original wall structure, and they are prone to fall in harsh environments; Water-saving irrigation leads to a poor living environment for planted plants, and it is difficult to maintain and manage later
