Description

  The present invention relates to a greening planting protection panel so that a load is not directly applied to a planted product.

Various protective materials that prevent the plant from receiving a direct plane load have been developed. In addition to this, a material that closes the bottom and stores water is disclosed in, for example, JP-A-2003-47346. Are listed.
JP 2003-47346 A

  The one disclosed in Japanese Patent Application Laid-Open No. 2003-47346 can be laid continuously on a building rooftop or a parking lot by connecting a planting container for greening, and is optimal for inexpensive greening with water retention and heat insulation effects. Concerning planting containers, a plurality of storage walls are erected on the bottom peripheral surface where the connecting part is drilled to form a concave storage tank, and a plant protection support pillar that is horizontally supported by connecting ribs is integrated. It is the planting container for tree planting which laminated | stacked the cultivation soil and mulching material which consist of a water quality adjusting material, an artificial lightweight aggregate, and planted lawn etc. in each storage tank of the cultivation container formed specifically.

  In the case of this planting container for greening, the structure of the unit body of the storage tank 2 is not clearly shown. Therefore, it is not clear how the support column 4 of the storage tank 2 is supported by the connection rib 5, but it seems to be separate support of two surfaces, three surfaces, and four surfaces. Further, the intermediate support column 10 is erected from the bottom portion 11 and has no ribs that resist horizontal load. When such support pillars 4 and 10 receive a load in a complicated direction due to the steering operation of the vehicle entering the parking lot, they cannot sufficiently resist and are likely to be deformed.

An object of this invention is to provide the greening planting protection panel which can fully protect with respect to the load of a various direction, and can protect a planting plant.
Another object of the present invention is to provide a greening planting protection panel that is not bulky when laminated and is convenient for storage and transportation.
Other objects of the present invention will become apparent with reference to the following description and drawings.

  The first planting protection panel according to the present invention is composed of a plurality of unit bodies. The unit body has a column part and a skirt part. The column portion is cylindrical, and one end surface on the axis line is closed by the top plate portion, and an inner rib protruding from the top plate portion in the axial direction is formed on the inner wall surface. The skirt portion is continuous to the column portion on the side opposite to the top plate portion, and has a flange on the outer periphery of the end, along the slope of the outer surface, and its height is low on the column portion side and high on the flange side. It has ribs. A plurality of unit bodies configured in this way are integrated at the outer end surfaces of the flange and the rib to form a planting panel having a planting space between the pillars.

  The horizontal and diagonal intervals between the pillars of each unit body are set so that the shoe does not fall by making it smaller than the width of the shoe sole and the tire does not enter by making it smaller than the width of the tire. Shall be. As an example, when the unit bodies are arranged at equal intervals in the vertical and horizontal directions, a diagonal of 112 mm or less is preferable, but the present invention is not limited to this.

  In addition, when the outer ribs are projected from the upper end of each column part, when the soil filled in the planting space contracts due to rain or load, etc., in the case of a planted plant rooted like a lawn, This root is caught by the outer rib and does not follow the contraction, and is separated from the soil. If this happens, water and nutrients cannot be supplied, and it will die. In particular, in the method of placing on the panel without cutting the lawn and rolling with a roller, the lawn is not easily sunk and is placed between the pillars. When the soil sinks due to rain or the like, a gap is created between the lawn and the soil, and it dries out easily. Moreover, even if the turf can be sunk well, if there is a rib in the recess, the turf is caught on this rib and the soil does not drop when the soil contracts, creating a gap.

  Therefore, each is an example, but if the length of the pillar portion on the axis is 50 mm and the outer rib protrudes from the bottom, it can follow the sedimentation well and prevent separation. When the height of the upper outer rib is 20 mm, the soil is connected to each other across the outer rib, and the roots of the planted material such as turf can be freely stretched.

  Increasing the number of unit bodies increases the area per panel, which is suitable for a wide laying area. However, the number is determined appropriately in consideration of manufacturing and handling problems. In addition, this panel includes a connecting tongue piece and a tongue piece receiver on the side surfaces, and can be connected and developed on a plane in the same manner as a normal panel by engaging and fixing both. When the standing wall is formed on the outer peripheral edge of such a panel, the panel itself is reinforced and the panels are easily connected to each other. This panel can be connected and developed in the vertical and horizontal directions as usual, and in the case of the present invention, a tongue piece and a tongue piece receiver are formed for connection and fixed with a pin.

  The unit bodies themselves can be stacked because the inner ribs are formed only on the pillars. Of course, even if the unit body becomes a panel, if the pillar part of one panel is placed in the skirt of another panel, They can be stacked, are not bulky, and are convenient for storage and transportation.

  Remove asphalt on the laying surface, dig the floor and roll it. Spread the soil-improving material and crushed stone agitation and roll. The greening planting protection panel of the present invention is laid. Lay the soil on the laid panel. The soil is filled in a planting space between the adjacent skirt portions and the cylindrical portions. Plant plants for greening in this land. In the case of turf, it becomes turf with soil. If the sun passes after flooding, the plant will be able to settle and grow.

  When a pedestrian or vehicle is placed on the panel, a load is applied to the top plate. The pillar part has an inner rib in the axial direction on the inner wall surface, the skirt part is continuous with the pillar part on the opposite side of the top plate part, has a flange on the outer periphery of the end, and follows the inclination on the outer surface. Since the outer rib is low on the pillar side and high on the flange side, the pillar part and the skirt part do not buckle even with a large load, and from the bottom part of the flange through the skirt part from the pillar part It is conveyed to the ground. Therefore, no direct load is applied to the customer soil filled in the gaps between the adjacent skirt portions and the column portions, and the plant planted in the cultivated soil, and no vegetation is caused.

  Since the height of the outer rib is low on the pillar portion side and high on the flange side, the roots of the planted material can easily extend to the adjacent planting area, and good planting becomes possible.

In the second planting protection panel according to the present invention, the inner rib protruding from the top plate part reaches the open surface of the skirt part through the pillar part with respect to the first panel, and pores are formed on the open surface. It is different in the configuration equipped with.
