Description

Building roofing system and its construction method {Construction Method for Roof-top Planting and Irrigation System}

The present invention relates to a building roof layer greening system and a construction method thereof, and more particularly, to a waterproofing process of a concrete base surface, a rooting process for preventing root penetration of vegetation materials, and a work process related to drainage processes. The present invention relates to a building roof layer greening system and its construction method, which can secure the organic connection structure of the plant, increase the performance and durability of waterproofing and waterproofing, and achieve the smooth vegetation of vegetation materials without additional management.

In the current urban environment, green space is almost disappeared due to the expansion of high-rise buildings and commercial facilities with the development of industry, and environmental pollution in urban areas due to the absence of such green space is emerging as a serious social problem. There is an urgent need to secure green spaces. In order to meet these demands, in recent years, as a part of the improvement of the urban environment, there has been an increase in rooftop greening that can secure green space by planting many plants and trees on the roof of buildings, and the government has enacted ordinances related to roof greening. It is forecast that demand will continue to increase in the future.

Roof greening refers to the installation of planting and landscaping facilities after the soil is built on the roof of a building. In the construction of modern urban rooftops, the roof gardening is receiving great attention as a way to reduce various environmental loads such as improving aesthetics, providing rest space, supplying oxygen in the city, preserving ecosystems, and conserving energy in buildings. It is expected to increase further.

In the conventional rooftop greening system, as shown in FIG. 1, the waterproofing layer 14 is coated on the upper surface of the rooftop slab on which the protective pressing layer 12 composed of concrete is constructed, and the pitcher pet 16 is disposed on the waterproofing layer 14. ), A permeable layer 20 composed of a permeable sheet 17 and a drainage soil 18, and the upper part of the permeable layer 20 is a plant-based layer 22 made of general soil or lightweight soil, which is the basis for growing plants. Will be added to the construction.

Another example of the rooftop recording system is the method of forming artificial ground on the slab surface of the rooftop and planting plants and shrubs thereon. The artificial ground method is first, by laying a PVC waterproof sheet on the slab or by applying a urethane waterproofing agent to form a waterproof layer, laying a waterproof sheet on the waterproof layer, and forming a permeable drainage soil such as perlite on the waterproof sheet In order to prevent the soil of vegetation layer from losing to drainage layer, nonwoven fabric is laid on drainage layer to form vegetation layer.

In the above-mentioned rooftop greening system, the root problem is pointed out as the biggest problem due to poor drainage of drainage layer in the short term. In the long run, vegetation roots penetrate into concrete structure of building due to poor rooting layer. It is pointed out that the weakening of the durability of the building by generating a big problem. The environment of the rooftop greening creates a condition of damage that can be invaded by the roots of planted plants, so that all waterproof and waterproof layers should be able to cope with it.

In order to stabilize the rooftop recording, a safe foundation should be constructed on the structure to which the rooftop recording part (planted part) is to be applied so as not to affect the structural stability and durability. It can be called the formation of a waterproof layer which is basically installed on the roof top and a waterproof layer to protect the waterproof layer from a rooftop recording part (plant, water, soil, fertilizer, etc.).

The fundamental reason for installing the root barrier layer is to prevent the rooting of the plant roots generated when planting construction on the upper part of the structure. The growth of plant roots is so strong that they penetrate the waterproofing material, and even the structure, that is, the case of the concrete structure, occurs, which acts as a major factor to shorten the life of the structure due to the crack of the structure.

In order to solve this problem, a method of forming a root barrier layer before roofing greening has been developed and used recently. As the method for constructing the rooting layer, the rooting method is a method of processing the roots so that the root does not easily fall to the bottom by laying a nonwoven fabric on the drainage plate during planting work in the aspect of landscaping work. It is using a close-up method to lay the polymer sheet so that the root does not directly touch the waterproof layer. However, none of these methods of construction work is a fundamental solution to the basic work, and the reality is that it is not generally accepted due to lack of engineering proof of the technology.

As mentioned above, the rooting construction in two aspects is caused by the failure to grasp the growth principle of the plant root, and has a problem in using it as a raw rooting material.

More specifically, the nonwoven fabric used in the aspect of landscaping construction may use a general polyester or a polymer nonwoven fabric produced by improving the performance. Do not deteriorate the drainage function to enter the only function that primarily blocks the rooting of the roots. Therefore, the roots of planted trees or plants have a property of penetrating into the gaps when the waterway is formed in a fine gap due to their characteristics, and thus the roots of the nonwoven fabric have a shape that is easy to penetrate. A problem occurred.

The PE film used in the waterproofing work is a far better development method compared to the non-woven fabric used in the landscaping work.The PE film has chemically and physically stable properties on the waterproofing layer to protect the waterproofing layer from the penetration of plant roots. By sticking to form a rooting layer is to prevent the sticking force of the plant roots to reach the waterproof layer. However, the PE film is weak in bonding stability because the joint is constructed with adhesive or adhesive tape, which becomes a main weak spot to form a waterway, and thus, the root film is active, thereby reducing the rooting effect. The question of effectiveness has been raised.

Accordingly, the present invention has been proposed to solve the above problems, and establishes a safe foundation by organically connecting each type of work required from the waterproofing process of the frame bottom surface to the drainage process during the greening of the roof layer of a building. It reliably responds to crack formation or behavior of concrete structures, prevents deterioration of the waterproof layer due to constant wetting conditions of the soil layer due to flower bed composition, and enables seamless vegetation of trees or shrubs without additional management. The object is to provide a floor recording system and a construction method thereof.

In order to achieve the above object, the present invention, the asphalt primer layer applied to the concrete base surface of the building roof layer; A first rubber asphalt coating waterproof layer laminated on the asphalt primer layer; A stretch asphalt felt layer laminated on the first rubber asphalt coating waterproofing layer; A second rubber asphalt coating waterproofing layer laminated on the stretch asphalt felt layer; An asphalt felt sheet waterproof layer laminated on the second rubber asphalt coating waterproof layer; Root sheet layer laminated on top of the asphalt felt sheet waterproof layer; A drain plate installed on the root sheet layer and having a water storage function and a drainage function for water supply of vegetation material; Non-woven mat is installed on the drainage plate, and prevents the sticking of the vegetation roots and the loss of vegetation soil and the soil filtration layer; And it provides a building roof layer greening system comprising a vegetation soil layer stacked on top of the nonwoven mat.

In addition, the present invention comprises a first step of setting a drain position in the frame bottom and the wall portion of the building roof layer, and forming a core hole in the drain position to install the drain; A second step of applying a gradient from the frame bottom to the drain so that water can be smoothly drained and performing a mass plastering process; A third step of constructing a flower bed wall in the frame of the roof layer; A fourth step of constructing a waterproof layer on the bottom surface of the frame; Stacking a waterproof sheet layer on top of the waterproof layer; A sixth step of installing a drain plate having a water storage and drainage function on the upper part of the root sheet; A seventh step of installing a nonwoven mat on the drainage plate to function as a prevention of sticking of vegetation roots and a loss of vegetation soil and a soil filtration layer; And an eighth step of performing vegetation soil filling on the nonwoven mat.

As described above, according to the features of the present invention, the following effects are realized.

First, when constructing the roof layer of the building, it is a safe foundation for the structure to be applied to the rooftop recording by organically combining the various constructions such as draft construction, drain location selection and installation, waterproof layer, weatherproof sheet layer, and vegetation soil layer construction. By improving the structural stability and durability, and at the same time it can reliably prevent defects of roofing greening, and can improve the workability by unified roofing greening construction.

Secondly, the drainage is smooth through the drainage plate having both the bottom of the skeleton and the drainage and drainage functions, and it is possible to promote growth by supplying sufficient moisture to the vegetation.

Third, by laminating two layers of HDPE film on the sheet of waterproof together with the waterproof layer, it can reliably cope with crack occurrence or behavior of the concrete structure, and prevent deterioration of the waterproof layer caused by the constant wetting conditions of the soil layer due to flower bed composition. It can fundamentally block the penetration of vegetation roots.
