Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening method for a concrete placing surface using an anchor pin for planting a plant such as a shrub or a tree on the surface placed with concrete such as a rooftop or a veranda.

[0002]

2. Description of the Related Art Since urbanization is progressing and heat energy emitted from high-rise buildings such as office buildings and condominiums is one of the causes of global warming, improvement of green parks is being considered. However, since it is difficult to secure land for parks in urban areas, rooftops such as buildings and condominiums, balconies, etc. are being reconsidered as spaces for greening. However, since the rooftop, the balcony, and the like are concrete pouring surfaces, various structures and methods have been developed when constructing a garden on this concrete pouring surface.

As a general means for constructing a garden on a conventional concrete pouring surface, a pot for planting is used for planting, or as shown in FIG. 6, a concrete pouring surface A for constructing a garden. The fence part B is formed on the inside, the waterproof sheet C is laid inside the fence part B, the water supply / drainage pipe D and the like are laid on the fence part B, the water retaining material layer E is formed, and the embankment layer F is formed thereon to form the plant G. Was planting. At that time, there is no problem in the case of a shrub that is tall and does not grow, but in the case of a tall tree that becomes tall and large, a prop H is used as a plant to hold the plant G, or a plant is used. Root winding part Ga
The plants were kept stable by putting them in a basket or fixing pipes around the roots.

[0004]

However, although the above-mentioned conventional means have some sense of stability when the plant to be planted is a seedling, the range of rooting of the plant as growth is not sufficient. As a result, the balance between the underground part and the above-ground part is lost, and there is a problem that plants grown by strong wind such as building wind and wind and rain fall over. Therefore, when constructing a garden on a concrete pouring surface, there are means to use the pillars H or to form the embankment layer F to be thick, but in that case, the building greatly exceeds the design criteria for durability. There is a limit to the means for forming the embankment layer F thick.

The present invention solves the above-mentioned problems and, at the same time, places concrete into concrete using anchor pins that can stably hold planted plants without forming a very thick embankment layer for planting. The purpose is to provide a surface greening method, and the following measures have been taken.

[0006]

SUMMARY OF THE INVENTION A first invention to obtain a patent is to form a fence portion having a predetermined height on a concrete placing surface such as a roof or a balcony in a range where a garden is to be constructed. In addition to laying a waterproof sheet inside the part, form a space part that can store water to a predetermined height in the fence part, and form an overflow hole at a predetermined height of the fence part to maintain the space part in the fence part A grid-like basic reinforcing bar is provided on the base, a net is laid on the base, and a net body for preventing soil outflow is laid on the net body.

Basic pressing body inserted Laying and horizontally straddling the upper restraining body having annular portions at both ends between the fence portions facing each other in a lattice shape, and the anchoring bolt inserted between the retaining metal fitting inserted through the base pressing body and the annular portion of the upper restraining body. This is a greening method for the concrete placing surface using anchor pins, which is characterized by being fixed.

Therefore, the plant to be planted can be freely and easily assembled according to the height or thickness of the plant or the construction site, and the plant to be planted can be stably held in the mixed soil layer. . Moreover, since the anchor pins can be increased or decreased depending on the strength and direction of the wind, the fall of plants can be prevented without thickening the mixed soil layer.

As the anchor pin, a root-wound annular body that presses and holds the root-wound portion of the planted plant, a holding claw body that presses the root-wound annular body in four directions, and the entire holding claw body and basic reinforcing bars. And a connecting body that connects the parts.

Further, since the planted plant has its own weight including the entire fence part, the trees and the soil, and the basic rebar part, it is strong against strong winds and vibrations and does not use the pillars so that it does not disturb the building. Moreover, since the space where water can be stored is formed, the planted plant does not have to die even when it is dried.

A second invention to be granted a patent is characterized in that powdered coal is laid in a space capable of storing water in a fence to purify water quality and improve water retention. This is a greening method for the concrete placing surface using the anchor pins described. The present invention is to lay powder coal in the space portion formed in the above-mentioned first invention to purify the quality of the stored water and to improve the water retention.
