<Structure of Putting Green for Building Roofs>

1 is a sectional view showing the construction of a putting green for a building roof as an embodiment of the present invention. Referring to FIG. 1, a putting green 5 for a building rooftop sequentially laminates a waterproof layer 20, a root barrier layer 40, a drainage layer, a growing soil layer 90, and a grass 100 on the bottom surface of the building rooftop 10. It is configured by. Between the waterproof layer 20 and the root barrier layer 40 is bonded with an adhesive 30, the drainage layer is composed of a drain block 50, a protective net 60, a low drainage soil layer 70. In addition, it is preferable that the air-conditioning supply device 80 is installed in the lower layer of the growing soil layer 90.

The waterproofing layer 20 and the waterproofing layer 40 bonded with the adhesive 30 are not only laminated on the bottom surface of the building rooftop 10, as can be seen from FIG. 1, but also beside the building rooftop 10. It is preferable to also install on the wall surface. Therefore, the putting green 5 has a drainage block 50, a protection net 60, and a low drainage on a structure in which the waterproof layer 20 and the waterproofing layer 40 are stacked in a shape surrounding the wall and the bottom surface of the roof 10 of the building. The receiving soil layer 70, the heating and cooling device 80, the growing soil layer 90, the grass 100 in order to form a layered structure in a horizontal layer. The detailed structure and function of each layer is as follows.

1.waterproof layer

The waterproof layer 20 serves as waterproof, moisture proof and waterproof. That is, water does not penetrate into the rooftop concrete under the waterproof layer 20. It also prevents moisture from dissipating in the roof of the building. In addition, the grass (100) roots to prevent the penetration into the concrete also serves to complement (root supplement role). The waterproof layer is formed not only on the rooftop floor but also on the rooftop wall, and is preferably formed at a height of 25 cm or more from the floor.

The waterproofing should be completely waterproof not only to the floor of the roof of the building but also to the part of the side wall or the handrail wall. The waterproofing should be smooth and the foreign substances of the waterproofing agent should not be washed away by water. Epoxy waterproofing is also possible, but it is preferable to use an inorganic repellent coating waterproofing agent. The thickness of the waterproof layer 20 is to be in the range of about 1.5 to 2.5 mm, most preferably 2.0 to 2.2 mm. As will be described later, the waterproof layer is composed of a primer layer and a three-ply waterproof layer. An elastic nonwoven fabric is interposed between the waterproof layer to resist cracking.

2. The warmth layer

The waterproofing layer 40 basically has a function of waterproofing, and serves to supplement waterproofing and moisture proofing. That is, at the same time to prevent the grass (100) roots to penetrate the concrete, it protects the waterproof layer 20 to complement the waterproof to give a semi-permanent waterproof effect. The waterproofing layer 40 is also provided on the roof surface as well as the rooftop floor, similarly to the waterproof layer 20.

As the material of the root barrier layer 40, a plastic resin film is used, and a polyethylene film having a thickness of 0.2 mm or more is preferable. Because polyethylene film is a very stable polymer material, it is resistant to various chemicals and does not decay in soil. It is preferable to provide two layers on the waterproof layer 20 so that the total thickness of the root barrier layer 40 is 0.4 mm or more. This is to double the film to strongly resist the root pressure. Between the barrier layer 40 and the building wall and the joint portion of the film is fixed by bonding with a strong adhesive tape or adhesive.

Although the polyethylene film is preferable as the material of the root barrier layer 40, the present invention is not limited thereto, and a film of another kind of plastic resin having a root barrier function may be used.

3. drainage layer

The drainage layer prevents the grass 100 from being flooded by allowing the surplus water to be quickly drained, and has a proper moisture to serve to prevent the grass 100 from drying in the event of a drought. The drainage layer needs to have a structure that can smooth horizontal drainage as well as vertical drainage. To this end, in the embodiment of the present invention, the drainage layer is provided with a structure in which the drainage block 50, the protection net 60, and the low drainage soil layer 70 are sequentially stacked.

Drainage block 50 is for preventing the damage to the root layer 40 due to the low drainage soil of the upper layer and for the rapid horizontal drainage of excess water. As the specific gravity is 1.0 or more and does not float in water and does not decay, the drain block 50 is a grid block having a height of 20 to 50 mm. Therefore, since the hole 50a is drilled between the upper and lower surfaces (that is, extending in the vertical direction), the vertical drainage is easy. Openings 50b formed in four directions are formed at the lower end of the side wall, so that the horizontal drainage can be made smoothly. The material of the drain block 50 is preferably PVC (Polyvinyl Chloride), polypropylene (Polypropylene), polyethylene (Polyethylene), the color is preferably black.

The protection net 60 prevents the drainage block 50 from clogging due to the outflow of the low drainage soil of the upper layer and serves to protect the waterproof layer 20 from the outside. The size of the eye of the guard net 60 is preferably 20 mesh (mesh), but is not limited to this size may be any size that can prevent the outflow of soil. It is preferable to use a hole formed in a polyethylene film, but is not limited thereto.

Low drainage soil layer 70 is a layer that maintains the minimum moisture while allowing for good drainage. Auxiliarily promotes the development of grass roots and improves breathability, while maintaining a minimum moisture function to complement the function of the growing soil layer (90). The material of the low drainage soil layer 70 is a material that does not interfere with the growth of the grass, the water content is very low, the drainage capacity is good, it is preferable that the specific gravity is low in consideration of the maximum load problem of the building roof. The material composition of the low drainage soil layer 70 is selected from pumice, light aggregate, artificial light soil, and the like, and can be used with different mixing ratios. Pumice refers to clay expanded stone (calcite), volcanic stone (lava, permstone), and the specific gravity is preferably 0.3 to 0.6 and a diameter of 3 to 20 mm. As lightweight aggregates, industrial wastes such as waste styropol, waste plastics, waste ABS can be used. Artificial light soils include perlite, vermiculite, zeolite and the like. The vermiculite preferably has a specific gravity of 0.1 to 0.3 and a diameter of 1 to 5 mm, and preferably has a specific gravity of 0.2 to 0.4 and a diameter of 1 to 5 mm.

As an example of the low drainage soil layer 70, 50-90% of pumice stones mixed with clay swelling and volcanic stones based on the volume when the total volume of each constituent material before mixing is 100%, vermiculite 5 It is preferable to comprise at a compounding ratio of -25% and perlite 5-25%. However, as described above, the material composition of the low drainage soil layer 70 is made of pumice such as clay expanded stone (calcite), volcanic stone (lava, permstone), industrial waste such as waste styropol, waste plastic, waste ABS, perlite, Artificial lightweight soil such as vermiculite and zeolite and light aggregate may be used by improving the mixing ratio.

It is preferable to configure the low drainage soil layer 70 as described above, so that the total specific gravity of the low drainage soil layer 70 is 0.15 to 0.8 of dry weight ratio and 0.18 to 0.9 of saturated water weight ratio. The water permeability coefficient of the low drainage soil layer 70 is preferably 150 to 350 mm / hr, and the water storage amount is 5 to 25 L / m 3 or less, and the thickness is 5 to 25 cm.

4. HVAC pipe

As will be described later, the putting green grass is cold grass. Therefore, in particular, in the lower portion of the growing soil layer 90, the air-conditioning and heating device 80 may be installed for cooling in summer and auxiliary heating in winter. The grass 100 planted on the growing soil layer 90 is exposed to various pests, and when the temperature is high in summer, phenomena occur and become weak. On the other hand, if it is too cold in winter, there is a concern that the grass is easily damaged or the growth is reduced. Therefore, when the air-conditioning pipe is properly supplied with heating and cooling can improve the disease resistance of the grass and prevent the degradation of the grass can reduce the use of pesticides and can reduce the maintenance cost of the grass.

3 illustrates the configuration of the air conditioning and heating device 80 as an example. Referring to FIG. 3, the air conditioning and heating device 80 includes a pipeline 81, a circulation pump 82, and a water tank 83. The water in the water tank circulates to the building's main water tank or cooling tower. In that case it is cooled by the cold water flowing through the pipes in summer and by the circulating water at a higher temperature than outside air in the winter to provide heat. The pipe spacing of the pipeline 81 provided between the growing soil layer and the low drainage soil layer is preferably 20 to 40 cm, and the pipe diameter of the pipeline 81 is 10 to 50 cm. The material of the pipeline 81 has a high thermal conductivity and bends well, and should not be deformed under stepping pressure. As a material suitable for the air-conditioning pipeline 81, a pipe made of polyethylene or polypropylene may be used, and copper pipe, stainless steel pipe, or SUS pipe may be used.

5. Growth soil layer

In order to plant the grass 100 that will constitute the putting green 5, it is essential to form a growing soil layer 90. The growing soil layer 90 on the roof uses a relatively light material because the soil layer must be formed within a limited allowable load range. In particular, when a certain depth is required, the specific gravity of the soil is very important. Therefore, it is necessary to create a soil having a low maximum moisture content. In addition, the growing soil layer 90 should satisfy the basic conditions, such as air, moisture, nutrition, such as plants can grow, and should have good breathability and drainage affecting the initial germination. In addition, weed seeds, pest pests, heavy metals and the like should not be mixed, and must meet the growth characteristics of the grass (90).

As a material of the growing soil layer 90 to satisfy the above conditions, the inorganic heavy soil, the inorganic lightweight soil, and the organic-containing soil are mixed. As the material of the inorganic heavy soil, fine gravel and sand, and the material of the inorganic light soil can be used as expanded stone, volcanic stone, perlite, zeolite, vermiculite, and lime. The organic soil may include chaff (grind chaff), charcoal, bark, peat moss, boiled sawdust compost, sawdust, peat, and green carbon. As part of the growing soil layer 90 material, a mixed soil such as BioGro, K Soil may be used. It is preferable that the diameter of the particle | grains which comprise the growing soil layer 90 is 0.25 mm or less. As an example of the mixing ratio of each material constituting the growing soil layer 90, when the total volume of each constituent material before mixing is 100%, sand 70 to 90% based on the volume, vermiculite 5 -15%, crushed chaff 2.5-7.5%, peat moss 2.5-7.5%.

As the physical properties of the grown soil layer 90, the specific gravity is preferably such that the specific gravity is 0.4 to 1.4 and the saturated water ratio is 0.8 to 1.9. In addition, the water permeability coefficient is preferably 150 mm / hr or more, and the water storage amount is about 20 to 30 L / m 3. In addition, the pH is preferably 6.0 ~ 7.0, CEC (Cation Exchange Capacity) is 3 ~ 5me / ㎡, porosity is about 50%.

6. Grass

The grass 100 planted on the growing soil layer 90 may be formed by planting cold grass such as Bent grass or Kentucky bluegrass, or planting Roll grass.

As one embodiment, the total thickness of the putting green (5) is subdivided by each component layer so that the total thickness is about 232.6 mm, waterproof layer 2.2 mm, waterproofing layer 0.4 mm, drain block 20 mm, low drainage soil layer 100 mm, growing soil layer It can comprise about 100 mm and about 10 mm grass. In this case, the total weight per unit area of the putting green (5) at maximum water storage is about 203.88 to 253.88 kg / m2, and when the weight is broken down for each component layer, the waterproof layer is 1.89 kg / m 2, the waterproof layer 0.55 kg / m 2, Drainage block 1.44㎏ / ㎡, soil layer for low drainage 60 ~ 75㎏ / ㎡ (low water amount is 10ℓ / ㎡), growing soil layer 140 ~ 160㎏ / ㎡ (low water amount is 20 ~ 30ℓ / ㎡), grass 5㎏ / ㎡ (roll grass When planting, it is 20 kg / m 2).

On the other hand, beneath the drain block 50 may be formed with a hill (about 10% inclination) of about 300 mm with expanded polystyrene insulation. In this case, the difficulty of the golf game at the completion can be appropriate and cause interest.

Hereinafter, the construction method of the putting green for the roof of the building will be described in detail.

<Construction method of putting green for building roof>

1. Site Theorem

In order to construct the putting green 5, the site on which the putting green 5 is to be cleaned is cleaned up first. This operation is to remove the obstacles and protrusions on the roof in advance to prevent damage to the waterproof layer 20, the root layer 40, etc. after construction. In addition, it is preferable to thoroughly clean so that the waterproofing is good.

2. Form waterproof layer

In order to form the waterproof layer 20, an inorganic elastic permeation coating waterproofing agent is applied several times. That is, a primer is applied up to a height of 25 cm or more from the bottom of the building roof top 10 and the side wall, and after the primer is dried, apply a waterproofing primer. After the initial waterproofing, crack-resistant nonwoven fabric is added to the joint between the floor and the wall. It is preferable to coat the waterproofing agent twice on it to form a three-ply waterproofing layer 20.

3. Formation of rooting layer

The rooting layer 40 is formed by spreading a plastic resin film (preferably a polyethylene film having a thickness of 0.2 mm) on the waterproof layer 20 in duplicate. The root barrier layer 40 is attached to a height of 25 cm or more from the bottom of the wall and fixed with adhesive tape or adhesive. When attaching the film, overlap the joints by 10cm or more and fix it with an adhesive to prevent the moisture on the ground from penetrating under the film and to protect the physical stimulus of the waterproof layer.

4. forming slope

In the case of the putting green 5 composition, a hilly area (within 10% inclination) of about +300 mm may be formed of extruded polystyrene insulation before forming the drainage block 50. Then, the difficulty of the golf game at the time of completion can be appropriate and induce interest.

5. Drainage layer formation

First put the drain block (50). An example of the drainage block may be a standard block SBK-3030, a 20 mm thick lattice block, which is placed on the root barrier layer 40 so that the vertically drained water is smoothly drained horizontally in the basement. A guard net 60 (for example, 20 mesh) is laid on the drain block 50. As described above, the purpose of the present invention is to prevent soil loss at the top and protect the waterproof layer 20 and the root barrier layer 40 from external shocks and the like. On the guard net 60, the low drainage soil mixed with the above-described materials, for example, pumice, perlite, vermiculite, etc., is evenly laid to a thickness of about 100 mm to form a low drainage soil layer 70. do.

6. Laying of air conditioning unit

Pipes of the air-conditioning and heating device 80 are laid on the low drainage soil layer 70 so as to be spaced in and out of 30 cm, for example.

7. Formation of growing soil layer

The above-mentioned growing layer soil (for example, the growing soil with a specific gravity of 1.2 to 1.3 and a saturated water ratio of 1.4 to 1.6) on which the air conditioner is installed is laid evenly with a constant thickness (for example, 100 mm). At this time, if necessary, the compound fertilizer (17-21-17) is sprayed on the soil for upbringing in an amount of, for example, 50 g / ㎡ and mixed evenly.

Sculpting is made inclined in consideration of surface drainage and surface undulation, and sprayed with water. On top of that, 80 ~ 100 ㎏ roller (Roller) to be thoroughly compacted, so that there is no small irregularities on the surface.

8. Grass layer composition

The grass 100 of the putting green 5 is sown by planting cold grass or rolling grass. In the case of the composition for putting green, it is preferable to plant the Hanji type Kentucky bluegrass in the case of forming the Korean paper Bent grass, the gate ball field, or the like.

When sowing seed, the sowing is carried out so as to have a density of 8 g / m 2, a germination rate of 80% and a purity of 96%, for example. After the seeds are evenly sprinkled in two directions, rake is applied, and then the dried clay is covered with a thin layer of about 1 mm and chopped with a roller. It is then covered and irrigated with 65% shading nets.

When planting roll grass, the cutting height should be 7-10mm and the cutting thickness should be 20mm or more. The size of the herd is preferably about 1.8m x 0.3m, or about 1.54m x 0.65m. When planting, the top of the soil is carefully replenished, knocking it with a wooden hammer and finishing it flat. Topsoil is the same as topsoil, so that it is sprinkled to cover about 1/2 of the leaves and watered well.

On the other hand, although not described in detail above, when setting the load of the soil layer, the load acceptance criteria of the target building are limited, so 100 kg of evacuation load and 4 kg of snowfall during a disaster and 254 kg of weight at the maximum function of the roof putting green are allowed. Putting green of the present invention should be applied to the building more than 360㎏ / ㎡.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above embodiments. Those skilled in the art will appreciate that modifications can be made in accordance with the spirit of the present invention, and such modifications also fall within the scope of the present invention.

According to the configuration of the present invention, first, there is an effect of expanding the neighborhood sports facilities by the conversion to eco-city and the creation of functional grass. Green soil of existing golf course should be more than 300mm thick, so the roof load problem cannot be solved when applying this standard. By developing low drainage soil, it can be used as a neighboring sports facility on the rooftop of the city, and can be used as a golf putting green and gate ball ground. According to the present invention, secondly, semi-permanent waterproofing is economical. Many years later, water leakage and waterproof problems arise due to factors such as expansion of summer, freezing and shrinking of winter, and decomposition by UV rays. It has a semi-permanent waterproof effect, which is economic benefit. Third, there is an effect of reducing the cooling and heating costs in the interior of the top floor. It can save 30% of heating cost and 50% of cooling cost, and it can reduce the peak time during cooling in summer, which can save national energy and reduce environmental damage caused by refrigerant. Fourth, it has the effect of preventing urban heat island phenomenon and air purification. When the temperature of the rooftop surface is 46 ° C in summer when the temperature is 32 ~ 36 ° C, the lawn is about 26 ° C, so the city temperature can be lowered. Also absorb CO ₂ from the 12 hour melt 1ha 900kg and 600kg release oxygen and thereby purify other toxic gases. Fifth, it is effective in reducing urban flooding and rainwater purification. Low water per 1 m ² grows soil 20-30ℓ, drainage soil 10ℓ, which reduces urban flooding, and slows down the flow rate to purify rainwater by absorbing dust.
