Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a windbreak pergola that weakens the wind in a building.

``Conventional Technology'' One of the commonly used measures to prevent building winds is to plant trees around buildings and use windbreak trees to suppress building winds.

``Problems that the invention attempts to solve'' By the way, when planting trees around a building,
It is common practice to plant young windbreak trees and let them grow until they grow large enough. It was necessary to support the trunk of the tree while curing it, but the environment where it is exposed to building winds is a harsh environment for the growth of young windbreak trees, so it was necessary to grow the windbreak trees to a large size without dying during curing. It took a lot of effort to grow.

``Purpose of the invention'' This invention was made in view of the above circumstances, and can efficiently block wind from building wind by using windbreak trees, and has a curing function for windbreak trees, as well as reducing the space under the windbreak trees. The purpose is to provide a windproof pergola that can be used effectively.

``Means for Solving the Problems'' In order to solve the above-mentioned problems, the present invention provides a shelf constructed by assembling a plurality of beams vertically and horizontally with gaps formed between each beam, and this shelf. A plurality of support columns are installed on the ground on the side of the high-rise building to support the shelf at a predetermined height from the ground, and the upper part of the trunk is attached to the ground below the shelf, and the upper part of the trunk is attached to the ground above the shelf. The tree is made up of a windbreak tree that is planted out in the open space, and a support member that is supported by beams and supported within the gap and supports the trunk of the windbreak tree.

``Function'' The windbreak tree performs a windbreak function, and the support members support the trunk of the windbreak tree to provide protection for the windbreak tree, making the space between each support pillar multipurpose as a plaza or parking space. Available.

Embodiment FIGS. 1 and 2 show an embodiment of the present invention, in which a windproof pergola P is installed on the side of a high-rise building A. This windbreak pergola P is constructed by combining a concrete pergola part 1 and a plurality of windbreak trees T. The pergola section 1
A plurality of support columns 1B are attached to the lower surface of the joints between the shelf section 1A, which is constructed by assembling beam materials 1a in a grid pattern, and each of the beam materials 1a to support the shelf section 1A at a predetermined height. It consists of Further, inside some of the gaps a having a square plane formed between the beams 1a of the shelf portion 1A, each beam 1a is
An X-shaped support member IC consisting of a cable-like body supported at the joint part of a is provided, and an annular support frame 1b through which the trunk of a windbreak tree T to be described later is inserted is formed in the center of this support member IC. has been done. The pergola section 1
is installed on the ground on the side of a high-rise building A with the shelf section 1A facing upward, as shown in FIG. A windbreak tree T is placed on the ground below the central part of a, and the central part of its trunk in the height direction is attached to the support frame 1.
It is supported and planted by b.

Next, the operation of this embodiment configured as described above will be explained.

When installing pergola part 1 on the side of high-rise building A, attach the trunk of a young windbreak tree T to pergola part 1.
The windbreak tree T is supported by the support frame 1b of
and install pergola section 1. If the windbreak tree T is supported by the support frame 1b in this way, even if the building wind blows on the windbreak tree T, the windbreak tree T will always be supported by the support member IC. The load on the trunk and roots of the windbreak tree T will be reduced, and the windbreak tree T will grow smoothly. Here, since the support member IC supports the trunk part of the windbreak tree T, and because the windbreak pergola itself has an upright frame structure, it was not used for conventional curing operations. It is now possible to support the part above the part supported by the splint, and the load acting on the trunk and roots is reduced compared to before, so the curing effect is better than before, and the windbreak tree T
can grow smoothly. Note that once the windbreak tree T has been cured, the support member IC may be removed from the beam 1a.

Further, the space between each support pillar 1B of the pergola section 1 can be used as a plaza, a parking space, etc.

3 and 4 show the results of a wind tunnel experiment using a model conducted to confirm the windproof effect obtained by the windproof pergola of this example. In Fig. 4, A' indicates a model of a high-rise building, and between the road on the east side of this high-rise building model A' (right side in Fig. 4) and the high-rise building model A', there is a gap a between each beam 1a. A windbreak pergola model P′ with a substantially triangular planar shape and no windbreak tree model was installed, while this windbreak pergola model P′ and a high-rise building model were installed.
This figure shows the measured wind force around the high-rise building model A' when wind blows from the south-southwest direction on A'. Furthermore, Figure 3 shows the wind force around the high-rise building model A' when the windproof pergola model P' is not installed.

As is clear from comparing Figures 3 and 4, when windbreak pergola model P' is installed, the wind force on the lee side of windbreak pergola model P' is clearly reduced, The effect of installing model P′ was confirmed.

In the above embodiments, the beams 1a constituting the windbreak pergola P can be freely assembled in a shape other than a lattice shape, and the shape of the support member IC that supports the windbreak tree T may also be arbitrary. In addition, windbreak tree T
There is no need to plant it below the center of the gap a between the beams 1a, and it may be planted along the support column 1B.

``Effects of the invention'' As explained above, the present invention consists of constructing a shelf from multiple beams, supporting the shelf on the ground on the side of a high-rise building with support columns, and attaching support members to the shelf. Because of the configuration in which the windbreak tree is supported by the windbreak tree, the trunk part of the windbreak tree can be supported on the shelf to protect the windbreak tree, and the windbreak tree can weaken the building wind. Since the structure supports the trunk part of the windbreak tree, it is possible to support the part higher than the splint support part conventionally used for curing windbreak trees, and young windbreak trees can be placed in areas where wind blows from buildings. Windbreak trees can be grown smoothly even when planted for windbreak purposes. Also,
The space between the support pillars has the characteristic that it can be used as a plaza or parking space.
