Description

  The present invention relates to a rooftop greening planter suitable for building a vegetable garden or a flower bed on an artificial ground such as a rooftop, and a rooftop greening system using the same.

  Many people enjoy gardening on the balcony using pots and planters. If there is a space larger than the balcony, such as the rooftop, and you want to make it a little more authentic, conventionally you laid a tarpaulin on the floor surface of the rooftop etc. and made a fence with a brick or concrete block on it, I put soil in the enclosure to make a vegetable garden and a flower bed. However, this method has problems that waterproofing and rooting treatment and enclosure construction are not easy, and the weight of the whole is increased due to the use of heavy bricks or concrete blocks.

Various light-weight planting facilities that can be installed relatively easily on the artificial ground have been proposed (for example, Patent Documents 1 and 2).
JP 2007-259716 A JP 2006-197865 A

  However, for example, Patent Document 1 is a technique for installing a planting facility on a folded-plate roof and cannot be applied to a flat roof surface. Moreover, patent document 2 is mainly for cultivating a mat-like plant such as a lawn or a small plant with shallow roots using a solidified soil, and requires a certain depth of soil such as root vegetables. Not suitable for plant cultivation. The other proposals are the same, and a technique suitable for building a full-fledged garden or flower bed on a flat artificial ground such as a rooftop is not disclosed.

  Moreover, although the planting equipment made from GRC (glass fiber reinforced cement), the planter made from FRP (fiber reinforced plastic), wood, etc. are used for the conventional planting equipment, these materials have the following problems. That is, the GRC planter is heavy, expensive, and difficult to construct. FRP planters are expensive and require a mold to manufacture. Wood is prone to degradation.

An object of the present invention is to provide a rooftop planting planter that is easy to transport and assemble materials, has a reduced overall weight, and is suitable for building a full-fledged vegetable garden or flower bed on a flat artificial ground such as a rooftop. That is.
Another object of the present invention is to provide a rooftop greening system that can promote rooftop greening.

  The rooftop greening planter of the present invention is a planter installed on the rooftop of a building or on a balcony, and is composed of four flat side plates, the outer shape of the rectangular shape of which is rectangular, and is surrounded by the outer frame. A tray installed with the outer periphery close to the outer frame at the bottom of the region, and a connecting hardware for connecting the tray and a pair of side plates adjacent to each other at the corner of the tray, The connection hardware has a plate shape bent at a right angle along the inner peripheral surface of the pair of side plates, and has an engagement portion that engages with an engagement hole formed in an upper surface of a corner portion of the tray, and A screw hole for screwing each of the pair of side plates is provided.

  This rooftop greening planter is a unit structure that assembles each material such as four side plates, trays, connecting hardware, etc., and each material is lightweight and not bulky, so it is easy to transport each material before assembly. . By making the side plate constituting the outer frame lightweight, the overall weight can be reduced. When assembling, the engaging portion of the connecting hardware is engaged with the engaging hole of the tray, the connecting bracket is attached to the tray, and the adjacent pair of screws held at right angles by the screws inserted into the screw holes of the connecting bracket. Each side plate is fixed to the connecting hardware. Thereby, a tray and a pair of side plate are connected. By performing this connection for each of the four corners of the tray, a rooftop greening planter is assembled. Since this assembly work does not require special tools and does not require high technology, anyone can easily assemble.

  The completed rooftop plantation planter can grow plants by putting culture soil in the space above the tray in the area surrounded by the outer frame. If the height of the outer frame is increased, the soil depth can be increased, and root vegetables and the like can be cultivated.

In this invention, it is good to provide the return which regulates disengagement in the state which engaged with the said engagement hole in the engaging part of the said connection metal fitting.
If a return is provided in the engaging portion of the connecting hardware, the connecting hardware will not come off the tray even if an external force is applied.

The side plate may be made of artificial wood, and the tray may be made of synthetic resin.
If the side plate is made of artificial wood and the tray is made of synthetic resin, both durability improvement and weight reduction can be achieved.

Further, the side plate has a hollow portion that opens at an end surface of the side plate, and is provided with an auxiliary hardware that is disposed over the cavity portions of a pair of side plates adjacent to each other and faces the connection hardware, and the auxiliary hardware is the connection hardware. It can be set as the structure which has a screw hole by which the screw penetrated to this screw hole is screwed.
If the screws for fixing the connecting hardware to the side plate are screwed into the screw holes of the auxiliary hardware arranged in the cavity of the side plate, there is no need to form a screw groove in the side plate itself. The selection range is expanded. Further, the tip of the screw does not protrude to the outer peripheral side of the side plate, which is preferable from the viewpoint of aesthetics.

Further, the tray has a bottom plate portion and a cylindrical portion that rises from the bottom plate portion and communicates vertically, and is installed with the bottom plate portion being in contact with the planter installation surface and fixed to the planter installation surface. A part of the suction cup may be inserted into the tubular portion so that it cannot be removed.
As a result, the entire rooftop plantation planter is fixed to the planter installation surface, and movement of the rooftop plantation planter due to strong winds or the like can be prevented.

  The auxiliary hardware 8 is used in combination with the first and second connecting hardware 6 and 7, and is perpendicular to the first and second connecting hardware 6 and 7, as shown in FIG. It is bent. A screw hole 81 made of a nut is provided in the vicinity of the corner portion. The warpage prevention metal piece 9 is a long metal piece having a U-shaped cross-sectional shape.

The assembly method of this rooftop greening planter will be described.
In the case of a planter installation surface on which a vinyl chloride waterproof sheet 101 is laid, such as on a rooftop, the tray 2 is first installed on the waterproof sheet 101 in the order shown in FIG.
As for the installation method, a solvent 102 for vinyl chloride is applied to the center of the planter installation location on the surface of the waterproof sheet 101 (FIG. 1A), and the suction cup 31 of the fixing suction cup 3 is pressed from above. Then, the waterproof sheet 101 and the suction cup part 31 are welded while the space 103 between the waterproof sheet 101 and the suction cup part 31 is in a negative pressure state ((B) in the figure). The suction cup 3 for fixing is firmly fixed to the waterproof sheet 101 by a synergistic action with the adsorption effect due to the space 103 being in a negative pressure state.

  Then, the bar-shaped portion 32 which is a part of the suction cup 3 for fixing is inserted into the cylindrical portion 23 of the tray 2, and the tray 2 is installed on the waterproof sheet 101. At this time, the fixing band 5 is inserted through the band insertion hole 33 of the fixing suction cup 3 in advance so that both ends of the fixing band 5 protrude above the cylindrical portion 23 ((C) in the figure). Both ends of the fixing band 5 are inserted into the band insertion holes 41 and 42 of the fixing disk 4, respectively, and both ends of the fixing band 5 are connected so that the rod-like portion 32 cannot be removed from the cylindrical portion 23. Thereby, the tray 2 is fixed to the waterproof sheet 101 which is a planter installation surface.

Next, the outer frame 1 is assembled around the tray 2.
As shown in FIG. 5, the engaging portion 63 of the first connecting metal 6 is inserted into the engaging hole 27 of the tray 2, and the first connecting metal 6 is attached to the tray 2. At this time, the overhanging portion 62 of the first connecting hardware 6 comes into contact with the standing edge horizontal portion 22 b of the tray 2. Since the engagement portion 63 is narrower toward the distal end side, it can be easily inserted into the engagement hole 27. When the engagement portion 63 is inserted into the engagement hole 27, the return 63a of the engagement portion 63 is engaged. The engaging portion 63 is not pulled out by being caught by the edge of the hole 27.

  Each side plate 11 is reinforced so as not to be warped by inserting a warp preventing metal 9 into the second cavity portion 12 from the top as shown in FIG. The two side plates 11 reinforced in this way are combined at right angles, and the auxiliary hardware 8 is disposed over the pair of side plates 11 in the first and third hollow portions 22 from the top. Then, the screw 10 inserted into the screw hole 61 of the first connection metal 6 is screwed into the screw hole 81 of the auxiliary metal 8 arranged in the third cavity portion 22 from the top of the side plate 11 and the second connection The screws 10 inserted through the screw holes 71 of the hardware 7 are screwed into the screw holes 81 of the auxiliary hardware 8 disposed in the first cavity portion 22 from the top of the side plate 11 and are held at right angles to the tray 2. A pair of adjacent side plates 11 are connected. Since the engagement hole 27 of the tray 2 is located slightly away from the inner surface of the side plate 11, when the screw 10 is tightened to connect the first connection hardware 6 to the side plate 11, the first connection hardware 6 is shown in FIG. It will be in the state which bent. By performing this connection for each of the four corners of the tray 2, the outer frame 1 is assembled, and the rooftop greening planter is completed.

  Since the above assembling work does not require special tools and does not require high technology, anyone can easily assemble. In addition, it can be easily dismantled, so it can be easily relocated during waterproofing repairs. This rooftop greening planter has a unit configuration in which each material is assembled on-site, and each material is lightweight and not bulky alone, so that it is easy to transport each material before assembly. Since the side plate 11 which comprises the outer frame 1 is a lightweight thing which has the cavity part 12, the whole rooftop greening planter is also comparatively lightweight. Even if it is lightweight, since the tray 2 is fixed to the waterproof sheet 102 as the planter installation surface by the fixing sucker 3 or the like, the rooftop greening planter does not move due to strong winds or the like.

  Since the finished roof planting planter has no hardware or screws for assembly on the outer peripheral side of the outer frame 1, the atmosphere is not impaired even when the outer frame 1 is made of artificial wood as in this embodiment. Since the screw 10 for fixing the first and second connecting hardware 6 and 7 to the side plate 11 is screwed into the screw hole 81 of the auxiliary hardware 8 disposed in the cavity 12 of the side plate 11, the side plate 11 itself There is no need to form a screw groove on the side plate, and the material selection range of the side plate 11 is wide.

  As shown in FIG. 8, a water-absorbing mat 104 is laid on the bottom of the tray 2 and the culture soil 105 is filled thereon, and then seeded or planted with seedlings to form a vegetable garden or a flower bed. Since the water absorption mat 104 is laid on the bottom of the tray 2, the water retention is excellent, and since the grid-like grooves 24 for storing water are formed on the bottom of the tray 2, a certain amount of water can be stored. . Therefore, later management is easy. If an outer frame with a high height is used, the soil depth can be increased and root vegetables and the like can be cultivated.

  In the embodiment shown in FIGS. 1 to 3, one tray 2 is installed in a region surrounded by one outer frame 1. However, as shown in FIGS. 9 and 10, It is good also as a structure which installed the several tray 2 in the enclosed area | region. Further, in the case of an artificial ground on which the vinyl chloride waterproof sheet 101 is not laid, the tray 2 may not be fixed to the planter installation surface by the fixing sucker 3 or the like.
