Description

[Technical Field]

[0001] The present invention relates to a greening structure in which a planting mat body is formed on a roof or rooftop where concrete has been poured or on a soilless surface paved with asphalt or concrete, and trees of any size can be planted using tree fixing tools, while the proliferation of weeds is suppressed. [Background technology]

[0002] As urbanization progresses in urban areas, high-rise buildings are being built in droves, and much of the ground is being paved with asphalt and concrete, reducing the amount of space for plants to grow, resulting in a decrease in the number of flowers and trees, and the loss of the natural environment.In particular, the roofs and rooftops of urban buildings are being occupied by waste heat facilities, and only waterproofing is applied due to floor load restrictions in order to reduce construction costs.There is a strong demand for greening in urban areas to bring healing and vitality to human society and restore the natural environment around our lives.

[0003] Therefore, planting and greening using the "Tree growing device for concrete pouring surfaces using tree fixing devices and tree growing method therefor" (Patent Document 1) and the "Greening method for tree plants and thin greening system" (Patent Document 2) developed by our company are becoming more popular.

[0004] However, the method in Patent Document 1 involves planting trees in fixed boxes using tree fixing devices, and while it is suitable for landscaping greenery on rooftops or in front of stores, garden designs that place planting boxes lack a natural feel compared to traditional garden construction.Furthermore, because a water storage area is provided within the greening area, there are weight limitations when installing it on existing buildings with strict load restrictions.

[0005] Furthermore, the method of Patent Document 2 involves planting tree plants in a target greening area where a corrosion-resistant net-like or lattice-like support is fixed to the surface of a thin planting mat, and not only planting flowers and sedum plants on soilless surfaces or on existing vegetation greening construction surfaces, but also providing a tree planting method and a thin greening system for this purpose that allows for easy greening, including trees.However, because the root ball fixing device uses wire, the system is limited to planting shrubs, so although it can be installed on existing buildings, the garden-like landscape is not satisfactory. Furthermore, this method requires that a root ball fixing device be installed on the surface of a thin planting mat, so that a long metal rod must be inserted directly and horizontally into the planting mat each time. This makes it difficult to ensure horizontality on uneven surfaces, making it unsuitable for wide-area greening. Furthermore, they do not have a weed-preventing function, and are unable to prevent the growth and proliferation of weed seeds that fly in, making them ineffective in preserving the landscape.

[0006] [Patent Document 1] Patent No. 3416799 [Patent Document 2] Patent No. 3896360 Summary of the Invention [Problem to be solved by the invention]

[0007] In order to solve the problems described in the background art above, the present invention provides greening using a thin planting mat or the like that prevents weed overgrowth and enables the planting of medium to tall trees in load-restricted areas on soilless surfaces. [Means for solving the problem]

[0008] To solve the above problems, the construction area is first enclosed with a partition frame, then, from the bottom up, plywood or Takilon, waterproof sheeting, root barrier sheeting, planting matting, welded wire mesh as a holding member, and finally the planting matting is layered on top to form a TK planting mat. A root-potted plant is then placed in the center of the contact surface (gaps at the four corners) between the planting mats. Hooked angle anchor pins are fixed to the welded wire mesh as a holding member, and each anchor pin is equipped with an anchor claw with a nut on its head. These are connected to each anchor pin with a looped wire threaded through a PVC tube, and the looped wire is tightened by tightening the nuts to secure the root-potted plant. The root ball area is protected with high-quality soil, and the entire surface, along with the TK planting matting, is covered with nonwoven fabric, vinyl, Russell netting, and pins, in that order. This greening method prevents scattering and soil erosion due to wind and rain, reduces weight, and suppresses weed growth. [Effects of the Invention]

[0009] By using the planting mat, the soil for the planting base is not washed away by wind and rain, and even when planting trees, there is no need to form a particularly thick mound, and medium-sized trees can be planted without using supports by simple work using anchor pins as tree fixing tools, so that a full-scale garden can be constructed in a short period of time at low cost.

[0010] Furthermore, by holding the root balls of the planted trees with anchor pins, the trees do not lean or wobble and will not fall over due to strong winds or vibrations, making it possible to create a green garden including tall trees even on the rooftops of existing buildings.

[0011] Furthermore, by covering the entire planting mat with three layers of nonwoven fabric, vinyl, and Russell netting, the growth and proliferation of flying weed seeds can be suppressed, reducing the labor required for maintaining and upholding greenery and preserving the landscape.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the greening method of the present invention will be described in detail with reference to the drawings. [Example]

[0014] Figure 1 is an explanatory diagram of a TK planting mat. Plywood is laid from below to level unevenness, or Takilon 1 is laid in places where unevenness is difficult due to significant azzation. Next, a waterproof sheet 2 about 0.5 to 2.0 mm thick is laid to prevent water leakage from irrigation, a root barrier sheet 3 about 1.3 to 2.0 mm thick to prevent roots from growing on the construction surface, a 20 mm thick planting mat 4, a welded wire mesh 5 as a retaining member, and a 30 mm thick planting mat 6 are layered and integrated into a TK planting mat 7.

[0015] The planting mat's internal structure is as follows: From the bottom, a black mulch sheet is layered; a Russell shading netting made of high-density polyethylene with a warp thread of 380 denier and an insert thread of 950 denier, with a shading efficiency of approximately 90-95%, and a water-permeable nonwoven fabric made of polyester fiber. On top of this, artificial soil (a mixture of 50% coco peat, 10% peat moss, 10% sphagnum moss, 20% bark compost, and 10% vermiculite) is compressed to form a base soil 20-50 mm thick. On top of that, a water-permeable nonwoven fabric made of polyester fiber through which plant roots can pass is layered; a Russell shading netting made of high-density polyethylene with a warp thread of 380 denier and an insert thread of 950 denier, with a shading efficiency of approximately 60-65%, and a black mulch sheet are layered in this order to form the top. The bottom and top parts are joined together to prevent the vegetation base soil from moving within the structure and to maintain its rigidity, and the structure is sewn together vertically and horizontally at specified intervals.

[0016] Figure 2 is an explanatory diagram showing how TK planting mats are laid without gaps, securing and holding a tree planted in place. First, the construction area is surrounded by a partition frame 12, and then TK planting mats 7 are laid. A root-potted plant 15 is placed in the center of the contact surface (gaps at the four corners) between the TK planting mats 7. A hook-shaped angle anchor pin 13 is inserted into the contact surface between the TK planting mats, and the mats are held in place using a welded wire mesh locking member. The head of the anchor pin 13 is equipped with an anchor claw with a nut, and each anchor pin is connected to this with a looped wire 14 passed through a PVC tube. The looped wire is tightened by tightening the nut, and the root-potted plant is planted and fixed in place to prevent the tree from falling over. The anchor pins 13 are inserted into the gaps between the TK planting mats 7, which makes it possible to visualize the holding and fixing positions with the welded wire mesh, making installation easier. The surface of the TK planting mat is covered with a protective sheet consisting of three layers of nonwoven fabric 8, black mulch sheet 9, and Russell net 10 to prevent the growth and proliferation of flying weed seeds, and the joints between each sheet are adhered with double-sided tape 11 so that no gaps are left.

[0017] Figure 3 is an explanatory diagram showing the anchor pins engaged with the welded wire mesh. The hook-shaped engaging portion at the bottom of the anchor pin 13 engages with the welded wire mesh 5 that makes up the TK planting mat, and the top of the anchor pin 13 engages the circular wire 10. To secure the circular wire 10, the head of each anchor pin is equipped with an anchor claw 17 with a nut 16. The circular wire 10 is passed through a PVC tube 18, and the nut 16 is further tightened to plant and secure the root-potted plant so that it does not fall over. The welded wire mesh 5, anchor pin 13, anchor claw 17, nut 16, and circular wire 10 are all plated or made of stainless steel to ensure corrosion resistance.

[0018] Figure 4 shows a root-potted plant secured in place by anchor pins. The root-potted plant 15 is placed with its roots facing downwards, in the center of the anchor pin 13 fastened to the welded wire mesh 5. The hook-shaped fastening portion at the bottom of the anchor pin 13 fastens to the welded wire mesh 5, and each anchor pin is connected to an anchor claw 17 with a nut 16 at its head by a circular wire threaded through a PVC tube. The circular wire 10 is tightened by further tightening the nuts 16, attaching the root-potted plant to the TK planting mat 7.

[0019] Figure 5 is an explanatory diagram showing that the roots of a potted plant are covered with good quality soil, vinyl, and Russell netting. The potted plant is attached to the TK planting mat 7 using the circular wire 14, nuts 16, and anchor claws 17, and a predetermined thickness of good quality soil 20 is poured in to bury the roots. This is then covered with vinyl 21 to prevent the growth and proliferation of weed seeds that may be blown in, and then covered with Russell netting 22 to prevent the vinyl 20 from scattering, and secured in place using pins 23. For the portions of the TK planting mat 7 other than where the root-potted plants 15 are planted, the "TK Weed-Prevention Planting Greening Method (Patent No. 7425253)" 19 is used. Planting holes are drilled in the vinyl 21, the desired plants are planted, and clay-improved soil is poured into the openings. By planting creeping plants such as ivy and sedum in the openings, the soil's surface moisture and temperature are maintained, allowing them to develop quickly and grow as runners, completely covering the vinyl surface. This prevents deterioration and wear of the vinyl and planting mat due to ultraviolet rays from sunlight, improving weather resistance. [Industrial Applicability]

[0020] This makes it possible to create garden-style greenery with medium-sized and tall trees on the rooftops and balconies of existing buildings in urban areas, where there are many existing concrete buildings with strict weight restrictions.This prevents the planted trees from being blown down by strong winds such as those blown by buildings or by wind and rain, and by suppressing the growth of weeds, it is possible to create greenery that maintains the landscape and significantly reduces the labor required for maintenance. Furthermore, the plants' ability to mitigate temperature rises and their oasis effect can help mitigate the heat island effect, provide a place of relaxation, and improve the urban landscape, making them highly likely to be used as part of future urban greening.

Claims

[Claim 1] The construction area is surrounded by a partition frame, and from the bottom up, layers are made of plywood or Takilon, waterproof sheeting, root barrier sheeting, planting matting, welded wire mesh as a locking member, and then another layer of planting matting to form a TK planting mat, with the root ball planted in the center of the contact surface (gaps at the four corners) between the TK planting mats. A hook-shaped angle anchor pin is held and fixed in place by the welded wire mesh as a locking member, and the roots of the plant in the root ball are attached to the anchor claw attached to the head of the anchor pin by tightening a looped wire threaded through a PVC tube, and then the anchor claw attached to the head of the anchor pin. The plant is then covered in the order of high-quality soil, vinyl, and Russell netting, preventing scattering and soil erosion due to wind and rain, reducing weight, and suppressing the growth of weeds.
