  The present invention relates to a method of performing blindfolding of middle and lower floors of buildings built adjacent to each other, such as a housing estate, by using a tree, and a tree height raising device used in the method.

2. Description of the Related Art Conventionally, in order to hide a veranda and windows of a building in a residential complex from being looked into from the outside, for example, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2006-307620), a hand around a veranda is used. As described in Patent Document 2 (Japanese Patent Application Laid-Open No. 2003-321818), a soundproof blindfold is provided by enclosing each house in a housing estate with a retaining wall that also serves as a hedge, as described in Japanese Patent Laid-Open No. 2003-321818. A method has been proposed.
In addition, in order to increase the greenery while blindfolding without damaging the natural scenery in the housing complex, planting trees by combining high trees and shrubs between buildings is also performed.

  However, as described in Patent Document 1, the method of covering the veranda with a net-like curtain or blindfold has a problem that each resident needs to blindfold individually and the natural scenery is impaired. .

  In addition, in the method described in Patent Document 2, when the retaining wall is raised in order to cover up to the upper floor, the bottom area of the retaining wall inevitably increases, and as a result, is left around the building. There is a problem that the shared site area is largely occupied by the retaining wall, and there is also a problem that the retaining wall impedes sunlight into the room in winter.

  On the other hand, according to the method of planting trees on the site between the buildings of the residential complex and blindfolding, if you plant broadleaf trees that are leafy in the summer and fallen in the winter without damaging the natural landscape, The problem of obstructing sunshine can be solved because the leaves fall in winter.

  However, in general, a tall tree having a height of 10 m or more increases the cost of planting and maintenance work such as periodic pruning, and grows to a height that allows blindfolding of higher floors after planting seedlings. There is a problem that it takes a long period of time until it grows, and when growing, there is a problem that the insects attached to the branches and leaves enter the room because the lower branches and leaves hit the veranda and the window on the lower floor.

  Therefore, the present invention eliminates the problems of the conventional blindfolding method as described above, and can perform blindfolding of the low and middle floors of the opposing buildings easily and effectively without impairing the natural scenery. To do.

  The blindfolding method between buildings according to the present invention is such that a plurality of types of hollow pillars having different heights from the ground are set up on the site between buildings according to the height of the floor to be blindfolded, and each hollow pillar body A tree is planted and blindfolded by a tree whose height is raised by a hollow column.

  Further, the tree height raising device of the present invention is used for a blindfolding method, and an anchor device is provided in a portion buried in the ground to prevent the fall, and a stay for preventing the tree from falling on the upper part. A fastener is provided.

  In the tree height raising device of the present invention, a joint is provided on the upper part so as to be freely connectable in the axial direction so that the height from the ground can be appropriately changed.

  According to the blindfolding method between buildings of the present invention, blindfolding can be performed easily and effectively by using a shrub that is easy to care for and inexpensively and raising it to a height equivalent to that of a tall tree with a hollow pillar.

  Further, a plurality of types of hollow pillars having different cross sections and heights from the ground can be erected, and the height of the hollow pillars from the ground can be set according to the floor of the building to be blindfolded.

  Because the blindfold between buildings is done by trees raised by hollow pillars, there is no change to the natural landscape for residents of the building. In addition, the ground around the hollow column body does not spread over a wide area as in the case where a tree is planted, and can be effectively used for a flower bed, a passage, or the like.

  By increasing or decreasing the number of connected hollow columnar units provided with joints, it is possible to easily obtain a hollow column having a height corresponding to the floor to be blindfolded.

The present invention will be described below with reference to the drawings.
FIG. 1 is a conceptual diagram of the blindfold method of the present invention, and does not show the actual tree layout. By planting a tall tree T on the tree raising device 1 erected on the site G between adjacent buildings A1 and A2, the height of the tree T is raised to a height equivalent to that of a tall tree and the line of sight is blocked. , Blindfolded.

The tree raising apparatus 1 shown in FIG. 1 is a hollow pillar, and can have an appropriate cross-sectional shape such as a circle or a square.
In the same figure, in addition to the tree raising device 1, the site G illustrates tree raising devices 1a and 1b of different types. These tree raising devices 1, 1a, and 1b have the same structure, although the sizes are different. An example of the size of the tree raising device 1 is that the height from the ground is about 4 m, the outer diameter is 1350 mm, and the height of the 2 to 3 m tree T to be planted from the ground is raised to about 8 to 9 m. The trees T can be blindfolded from the third floor to the fourth floor.

Further, the tree raising device 1a has a height of 2 m from the ground and a circular cross section, the outer diameter is 700 mm, the height of the tree Ta is about 3 m, and the total height is about 5 m. On the other hand, the tree raising device 1b has a height of 1.5 m from the ground, but the outer diameter is 700 mm, which is the same as the hollow pillar 1a, and a shrub Tb having a height of about 2.5 m planted at the upper end. Is raised to about 4m above the ground, and both are used for blindfolding up to the second floor.
Although not shown in the drawings, these tree raising devices 1, 1a, 1b are provided with a tipping prevention means so as not to fall down during an earthquake or a strong wind.
