The present invention relates to a rooftop recording system and a construction method thereof, and more particularly, it can be applied to a rooftop of an existing building without a large burden because the soil depth is low while the basic premise of securing structural safety, water resistance (durability) and economic efficiency is low. The present invention relates to a rooftop recording system, which is a low-cost, lightweight rooftop recording system, and a construction method thereof.

In general, the rooftop recording system refers to a greening facility that is landscaping on a single-story or high-rise roof. More specifically, it is a landscaping facility structure on an artificial structure separated from the ground surface (more than 1m from the ground). It is a community space arrangement that newly forms the ground as geology and uses it as landscape space.

This rooftop greening system not only meets the green space in the city by creating a green space on the roof of the building, but also installs various plants and creates a rest area to create an ecological environment for insects and plants. It provides a resting place for people, and furthermore, the increase of the roof garden will transform the city into a natural environment rather than an artificial city, which will naturally reduce air pollution.

In addition, the main reason for greening the roof of the building is to save energy because it has a great effect on the heat insulation and insulation on the top floor, and the greening can improve the scenery, adjust the temperature, clean the air, etc. The natural ecosystem can be restored by seeking symbiosis with small birds, insects, and fish. Besides these three reasons, there are disaster prevention, countermeasures against rainwater, privacy, and hobby life (horticulture, gardening).

Therefore, at present, attempts for greening the rooftops in order to save the aesthetics of buildings as well as the above reasons have been proposed and progressed. However, most of them are planted trees (trees, trees, ground cover plants) due to the structure and construction methods that correspond to the control weight type. Etc.), and the depth of soil was required more than 20cm, and it was impossible to apply to existing buildings, and it added economic burden to the landlord by separately separating the construction stage and the landscaping stage when constructing new buildings. As the soil load is heavy, the building load increases, and the greening method is also limited to partial greening, which prevents wider and more versatile greening. Various problems such as being followed were pointed out.

The present invention is to solve the above problems, on the basis of ensuring the structural safety, water resistance (durability) and economic feasibility, the target building can be applied to both new and existing buildings, but existing buildings cause ecological problems of the city Considering that this is a major factor, the existing building is designated as a priority, and the soil layer with excellent vegetation development and absorption and drainage power can be applied without any burden on the roof of the existing building, which occupies a relatively large proportion in the city. The main purpose of the present invention is to provide a rooftop recording system and a construction method thereof, which is a low-end rooftop recording system corresponding to a low management and light type.

In order to realize this, the present invention targets small trees or ground cover plants, which are generally easily obtained, and uses a light artificial lightweight soil while the soil depth is 20 cm or less, and also takes various front recording methods. It is to provide a low-maintenance lightweight rooftop recording system and its construction method that can minimize maintenance after construction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a cross-sectional state of the entry-level rooftop greening system of the existing building, Figure 2 is a view showing a cross-sectional state of the entry-level rooftop greening system of a new building.

First, the rooftop recording system according to the present invention is a low-maintenance and light-weight system, which can be applied to the rooftop of an existing building without a large burden because the soil depth is low. It must be taken into account as a general rule, and to do this, a structural safety diagnosis of the building is required.

Components of the main system according to the present invention is composed of the building envelope (1), planting base (11), vegetation layer (8) and the building envelope (1) is the artificial ground to support the rooftop recording system (10). Therefore, the structural safety diagnosis and the building envelope (1) must also go through a waterproof diagnosis because it must block the leakage of the building due to the rooftop recording system (10).

The rooting layer (2) of the planting base (11) protects the waterproofing layer and the building from the roots of the plant, as well as the waterproofing layer from mechanical and physical shocks during construction, and the drainage layer (5) is flooded with the rooftop greening system. To prevent drowning, the filter layer 6 functions to filter the fine-grained soil washed out in the rain so that it does not flow out to the lower part of the system, and the growing soil layer 7 is a foundation for the continuous growth of plants and a rooftop greening system (10). ) It should be light weight because it takes up most of the weight.

Vegetation layer (8) is the top component of the entry-level rooftop recording system, so the selection conditions of the applicable plant is as small as possible, easy to manage and can reduce the wind resistance to the water pipe; Herbaceous species with dense leaves and branches for protection against solar radiation and protection of soil surface; Shallow and deeply spreading laterally than myocardial myocardium, deep rooted; Plant species that are not very active in the growth of plant ground and underground; Species that do not require battery pruning and are easy to manage; First species that are highly resistant to dryness and light resistance, moisture resistance, cold resistance, weather resistance, and disease resistance; Even after transplantation, it is desirable that the species is fast to recover and recover quickly even after injury.

The roof-type greening system 10 of the existing building according to the present invention, as shown in Figure 1, sequentially from the building envelope (1) to the ground floor (2), pressed concrete (3), waterproof layer (4), drainage (5), the filter layer (6), the growing soil layer (7), the vegetation layer (8), the new building's popular rooftop recording system (10a) is a heat insulation layer directly on the building envelope (1a) as shown in FIG. (9) is formed, and the heat-insulating layer (9) is sequentially formed on the waterproof layer (4a), the drainage layer (5a), filter layer (6a), growing soil layer (7a), vegetation layer (8a).

To explain each of these extra structural features,

A-1. A warm floor

When the waterproofing construction is performed again on the existing building envelope (1) to form the waterproofing layer (2), when the waterproofing layer (4) itself does not have a protection function, the protection of the waterproofing layer (4) must be considered. Its main function is to protect the waterproof layer (4) from the physical damage during construction and various environmental pressures (ultraviolet rays, wind, etc.), and the other is a rooting function to protect from plant roots.

As said root-proof sheet, a polyethylene foam sheet and polyethylene vinyl are preferable.

A-2. Waterproof layer

The waterproofing layer (4) (4a) serves to block the water leakage of the rooftop recording system (10) (10a) to the building and has the greatest effect on the durability of the rooftop recording system, and the precision and durability of the waterproofing Along with the permissible capacity, it is an important issue in determining the durability of rooftop greening.

The waterproofing material on the premise of the roofing greening is generally required for water resistance, in addition to water-tightness in which material components are not dissolved by moisture, resistance to roots of plants, chemical resistance against fertilization, and control, and corrosion by bacteria. Special performances such as resistance to pressure, pressure resistance to withstand the weight of the upper part and construction load are required.

The waterproof material is urethane, FRP composite waterproof, vinyl chloride (PVC) -based sheet waterproof.

A-3. Drainage

The meaning of the drainage layer (5) (5a) in the rooftop recording is as important as waterproofing, especially in the case of the diffusion rooftop recording having a soil depth of about 20cm, as in the present invention.

Drainage layer (5) (5a) is an important part directly connected to the growth of the plant and the safety of the structure, the drainage is the vertical drainage and growth soil layer (7) (7a) flowing from the top to the bottom of the growing soil layer (7) (7a) It can be divided into horizontal drainage that moves outward from the center of the drainage. In the drainage of growing soil layers related to vegetation growth, the vertical drainage is important, and when considering the rainfall characteristics such as heavy rainfall in the short term like Korea, The multiple of is important.

 A-4. Filter layer

The filter layer (6) (6a), which washes down the rainwater and prevents soil fines generated over time from flowing out to the lower part of the system, is a material (civil nonwoven fabric) that satisfies both filtration and permeability of fine grain soil. use.

A-5. Soil layer

In general, in the case of a shallow soil type, the soil layer 7 (7a) is grown mainly on artificial lightweight soil material.

A-6. Vegetation layer

Vegetation layer (8) (8a), which is a rooftop plant, should have weather resistance, cold resistance, and moisture resistance due to the poor environmental conditions of the rooftop. Possible and indiscriminate planting of ornamental arbors should be avoided.
Next, the construction sequence according to each of these structures will be described step by step.
The construction process of the rooftop recording system applied to an existing building includes the steps of forming a root barrier layer (2) made of polyethylene foam sheet or polyethylene vinyl on the existing building envelope (1); Curing the pressed concrete (3) to a predetermined thickness on the root barrier layer (2); Forming a waterproof layer (4) by selectively employing one of urethane, FRP composite waterproof, and vinyl chloride (PVC) based sheet on the pressed concrete (3); Forming a vertical drainage layer (5) flowing from the top to the bottom of the growing soil layer (7) on the waterproof layer (4); Forming a filter layer (6) of civil nonwoven fabric on the drainage layer (5); Forming a growing soil layer (7) mainly on the artificial light soil material on the filter layer (6); It comprises a step of forming a vegetation layer (8) for the target tree or ground skin plants on the growing soil layer (7)
The construction process of the rooftop recording system applied to a new building includes: forming a heat insulation layer 9 for external insulation in the new building envelope 1a; Forming a waterproof layer 4a selectively employing any one of urethane, FRP composite waterproof, and vinyl chloride (PVC) -based sheets without installing the pressed concrete 3 to a predetermined thickness on the heat insulating layer 9; ; Forming a drainage layer (5a) on the waterproof layer (4a); Forming a filter layer (6a) of civil nonwoven fabric on the drainage layer (5a); Forming a growing soil layer (7a) mainly on the heavy soil material on the filter layer (6a); It comprises a step of forming a vegetation layer (8a) for the shrub, arbor, ground cover plants on the growing soil layer (7a).

Rooftop greening according to the present invention as described above has a significant effect on the energy saving of building cooling and heating energy, because it takes a long time to transfer the outside temperature because the thermal conductivity is lower than the conventional non-green roof, reflection and evaporation of solar radiation by the green area The effect is to alleviate the urban heat island phenomenon, and the rooftop greening system of the soil within 10cm is effective in preventing urban flooding as it has excellent rainfall reduction efficiency of about 70% of the actual rainfall due to the absorption capacity and evaporation of the soil layer. In addition, it is a very useful invention with a number of remarkable effects such as air purification, water purification, noise reduction, urban landscape improvement, and building durability improvement.
