In the embodiment, a water-permeable tile is used as the upper plate 17, and synthetic resin plates are used as the bottom plate 19 and the side plates 21.

The tree 9 has a trunk 903 in the hole 1701.
Is located and the root 901 is supported by the support mechanism 11 in a state of floating in the space 23. As the tree 9, for example, evergreen trees such as cous, bayberry, sycamore, ubamegashi, mokkoku, oyster wax, holly are suitable. After the tree 9 is dug out of the soil, the root 90
For example, the soil attached to 1 is dried, dropped by a spray method, washed with warm water, and then soaked in a hormone solution.

The support mechanism 11 includes an outer annular frame 1101 fixed to the inner peripheral portion of the hole 1701 and an elastically deformable elastic member 11 attached to the periphery of the trunk 903.
032, an inner annular frame 1105 that supports the elastic member 1103, a plurality of upper support members 1107 that connect the outer annular frame 1101 and the inner annular frame 1105 at a plurality of circumferentially spaced intervals, and the outer side Consists of a plurality of lower support members 1109 that extend obliquely downward from the circumferentially spaced locations of the annular frame 1101 toward the center of the hole 1701 and a receiving member 1111 supported by the plurality of lower support members 1109. Has been done. The weight of the tree 9 is supported by the receiving member 1111.
The trunk 903 of the tree 9 is positioned in the horizontal direction by the elastic member 1103, and the standing state of the tree 9 on the box 7 is maintained by these.

The water supply mechanism 13 includes a spray nozzle 1301 attached to the lower surface of the upper plate 17 and a water tank 1303.

According to the tree unit 3 according to the embodiment, when the floor member 5 is spread, the floor unit 1 can be constructed by installing the tree unit 3 between the floor members 5. Therefore, the floor member 5 can be constructed by a construction worker. The work of laying and the work of installing the tree 9 can be performed at the same time, which makes it possible to shorten the construction period and reduce the cost. Moreover, the upper plate 17 on which the tree 9 is planted
Since there is no soil on the top, even if a pedestrian walks in the vicinity of the tree 9, problems such as dirty shoes and soil scattered on the floor 1 can be solved.
There will be no runoff to the top, and runoff soil will not collect in drainage channels. Furthermore, since the tree unit 3 supports the tree 9 with the root 901 floating and does not use soil, the tree unit 3 is lightweight and convenient to handle. In addition, in the embodiment, since the upper surface of the box 7 is formed of the water permeable tile and the drain pipe 25 is connected to the box 7, the tree unit 3 exerts the water collecting function and the water is not collected on the floor 1 when it rains. It is possible to prevent problems such as accumulation, and at the same time, the rainwater stored in the water tank 1303 can be used for supplying water to trees.

Next, the weight of the tree unit 3 will be described. For example, a case of planting trees with a height of about 4 m in a 1 m × 1 m section will be described as an example. According to the conventional method, a bed soil with a thickness of 40 cm and a drainage layer with a thickness of 15 cm are required. When black soil is used as the floor soil and gravel is used as the drainage layer, the weight of the floor soil is 560 to 680 Kg. The weight of the drainage layer is 255 to 315 Kg. When the black soil mixed with perlite is used as the floor soil and the perlite is used as the drainage layer, the weight of the floor soil is 360
The weight of the drainage layer becomes 15 to 30 kg. Tree 9 with soil attached to the root weighs about 200K
Since it is g, the total weight in a 1 m × 1 m section when using soil is 600 Kg to 1200 Kg.

On the other hand, in the tree unit 3, when the height of the box 7 is 55 cm, the weight of the frame 15 is 25 kg, the weight of the upper plate 17 made of the water permeable tile is 60 kg, and the bottom plate 19 and the side plates 21. The weight of 20Kg
Even if the weight of the support mechanism 11 is added, it is about 120 kg. In addition, the weight of trees without soil attached to the roots is about 10
Since it is 0 kg, the total weight of the tree unit 3 is 220 K.
It becomes about g. Therefore, the conventional structure is 600 Kg to 120
The tree unit 3 weighs about 225 kg, which is 0 kg, which is about 1/3 to 1/6 that of the conventional structure, so it is convenient to handle, especially on the second floor, third floor or rooftop. It is suitable to be installed in a place where its weight affects.

The structure of the support mechanism 11 is arbitrary,
It is not necessary to arrange it in the box 7 as in the embodiment,
It may be arranged on the upper surface of the box 7. Further, the upper plate 17 may be of a split type so that the trees 9 can be changed according to the four seasons, or the upper plate 17 can be detachably attached to the side plate 21.

[0014]

As is apparent from the above description, according to the present invention, when a tree is planted on a floor or the like, the construction period can be shortened and the cost can be reduced, and the floor is not soiled. Moreover, a tree unit that is lightweight and easy to handle can be obtained.
