Description

An Assembled Lightweight Roof Greening System

technical field

The utility model relates to the field of fixed building roofs, in particular to a roof greening system. the

Background technique

Roof greening generally refers to a form of space greening and beautification that relies on the top platform of a building to store water, cover soil and create a garden landscape. The general form is to directly lay the greening and its base soil, waterproof insulation layer, etc. on the roof by layer-by-layer laying method. Using it as a roof has the following limitations: 1) It has high requirements for the bearing capacity of the building structure and is not suitable for a large number of existing buildings; 2) It has high requirements for waterproof and thermal insulation structures, otherwise it will easily cause roof damage and water leakage; 4) Construction work flow It is complicated, the cycle is long, and the greening maintenance and renovation are difficult. 5) It is generally implemented on flat roofs, and it is more difficult to implement on sloping roofs.

Utility model content

In order to overcome the limitations of common roof greening, the utility model provides an assembled light-weight roof greening system, which can be flexibly applied to various building roofs without affecting the waterproof and heat preservation of the original building. At the same time, the construction and installation are simple and easy .

The technical solution adopted in this program is: an assembled light-weight roof greening system, which is characterized in that: the metal components in the vertical and horizontal directions are connected to form a rectangular grid unit, and the grid unit is fixed on the roof by metal columns Above, the finished potted planting box is placed in the space of the grid unit, and light planting soil and green plants are placed in the planting box, holes for drip irrigation are reserved in the planting box, and the drip irrigation main pipe is set on the grid unit Lay below, and then connect the drip irrigation capillary with the drip irrigation hole.

In this technical solution, in order to solve the survival rate of greening and the daily maintenance needs, a drip irrigation system is used for daily watering, fertilization and other maintenance of plants. The connection between the metal column and the roof is the main force-bearing component in the whole system. The connection between the metal column and the roof belongs to the existing technology, and any connection method in the prior art can be used, such as bolt connection, embedded part connection, etc.

The grid unit is supported by uprights and serves as the carrier of the finished potted planting box and the fixed end of the drip irrigation pipe network. The drip irrigation main can be fixed under the trellis unit by lashing. The finished potted planter can be secured to the trellis unit via the four bolt anchor points at the corners or by other existing securing means. In the above scheme, the inclination angle of the grid unit can be adjusted according to the roof shape and actual needs. Trellis units and metal columns can be made of square or any other form of metal components.

In this plan, the finished potted planting box can be divided into several small compartments. As a preference, light planting soil with a thickness of 80 mm to 120 mm is installed in each small cell. Of course, light planting soil of other thicknesses can also be determined according to the bearing capacity of specific plants and the roof. The plants in the finished potted planting box can be pre-cultivated in the nursery. This method is conducive to the nursery cultivation of the light green roof system, rapid installation on site, and daily replacement and maintenance.

The beneficial effects of the utility model are: the greening plants rely on the grid unit to form an overall green roof, and the weight is relatively small. Generally, the total weight per square meter is only about 20KG, which is far less than the live load of 200KG on the roof in the design specification. The bearing capacity requirement is small, and it can be flexibly applied to the roof of various new buildings, and can be implemented in a large area in the renovation of existing buildings to improve the city's landscape and environment. The green roof is separated from the original roof, which will not affect the waterproof and thermal insulation of the original building. At the same time, the air layer and green coverage formed are conducive to the thermal insulation performance of the roof. The components of the utility model can be prefabricated in advance and directly installed on site, greatly shortening the construction period. The grid unit combined with the drip irrigation pipe network together constitute a light-weight green roof system that can be maintained and flexibly disassembled.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a sectional view of the utility model.

Fig. 2 is a three-dimensional schematic diagram of the utility model.

Detailed ways

As shown in Fig. 1 and Fig. 2, the grid unit 1 is composed of square tubes respectively, and the metal column 3 below is the main structural support. The finished potted planting box 6 is placed in the space of the grid unit, and green plants 4 and light planting soil 5 are arranged inside. The finished potted planting box can be fixed on the lattice unit 1 through four bolt anchor points at the corners. The figure is only a schematic representation, and other methods of fixing can also be adopted in actual engineering.

The drip irrigation supervisor 2 and the dripper capillary 7 are hidden under the grid unit 1, because the dripper system belongs to ready-made mature technology, and does not belong to the scope of this patented utility model.

The above detailed introduction to the solutions provided by the embodiments of the present invention, for those of ordinary skill in the art, based on the idea of the embodiments of the present invention, there will be changes in the specific implementation and application range. To sum up, the contents of this specification should not be understood as limiting the utility model, and any changes made according to the design concept of the utility model are within the protection scope of the utility model.
