Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a protection board for roadside trees, etc., and more specifically, a protection board installed to protect the roots of roadside trees and plants planted on the road. This relates to protection boards for roadside trees, etc.

[Conventional technology]

Conventional protection boards installed to protect street trees are made of cast iron with multiple holes for water drainage, or a combination of protection boards with crosspieces installed at predetermined intervals within a frame. A protective panel is used.

[Problem to be solved by the invention]

However, the conventional protection board has a problem in that sunlight shines through the water drainage holes and protection bars, and weeds tend to grow and spread around the roots of the trees, making it troublesome to remove these weeds.

Additionally, when removing weeds, heavy protective bars must be removed, which results in poor work efficiency and problems such as weeds blocking the water holes and impairing water flow. .

Furthermore, since the protective plate is a heavy object made of cast iron or steel, it is difficult to transport, install, and remove, and the equipment cost is also high.

In addition, in terms of color, conventional ones are mainly black, which is not aesthetically pleasing due to its relationship with the cityscape and street trees.

Furthermore, even if painted or plated, the paint tends to peel off because it is constantly exposed to wind, rain, and sunlight.
Since it is easily scratched, there is a problem in that it is susceptible to rust.

Therefore, an object of the present invention is to provide a protection panel for roadside trees, etc., which has been devised to solve the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above object, in the protection board for roadside trees, etc. of the present invention, the protection board is formed by combining a plurality of protection boards whose light emission state can be adjusted within a frame, and the protection board has the following features: A plurality of protective bars are arranged in a grid shape at regular intervals intersecting the middle bar, and projections are provided on the front and rear sides of the protective bars in a stepped manner to block the incident light and to form water holes. It is a feature.

Further, the protection plate has a configuration in which the peaks of a pair of upper and lower protection members each having a protection bar provided with a peak are shifted from each other by a certain distance so as to block the incident light and form a water channel. ing.

[Effect]

Concrete blocks around the roots of street trees,
A frame is installed using frame members such as bricks, and a protection board is installed in combination within this frame. Bricks, blocks, etc. are placed below the joint between the protection boards on the tree side, and the protection board is installed. Install horizontally.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on the drawings.

The frame 1 is made of concrete blocks, bricks, etc. and surrounds the roots of the tree 11.
A stepped portion A on which the end portion of the protection plate 3 is placed is formed inside the frame 1, as shown in FIG. 3.

The frame 1 is formed by combining arc-shaped frame members 1e to form a circular frame as shown in FIG. 1, or by combining a straight frame member 1a and an approximately L-shaped corner frame member as shown in FIG. 1b to form a rectangular shape.

Further, the frame 1 may be formed into a polygonal shape by combining a straight frame member 1b and a corner frame member 1c, as shown in FIG.

The protection board 2 is a combination of a plurality of protection plates 3 formed by dividing the inside of the frame 1 into a plurality of parts, and the protection plate 3 has impact resistance, weather resistance, and tread pressure resistance. Made of flame-retardant, self-extinguishing synthetic resin.

Moreover, the protection plate 3 is arranged so as to intersect the middle crosspiece 4 and a plurality of protective crosspieces 6 at regular intervals, and is formed in a slatted shape.

In the case of the circular frame shown in FIG. 1, this protection plate 3 is manufactured in a fan shape.

Note that the upper surface of the protective crosspiece 6 is preferably located slightly above the upper surface of the middle crosspiece 4.

Further, the protection bar 6 has a protrusion 8 on the upper side of the rear side for preventing sunlight from entering from above.
At the same time, a protrusion 9 is provided at the lower part of the front and rear sides, and is configured in a stepped manner with a certain distance from the protrusion 8 when assembled, and the gap is formed in the water spout 7.

In this case, the rear end surface of the protrusion 8 and the tip surface of the protrusion 9 are preferably located on the same line in order to facilitate die cutting during molding.

Figure 4 shows another embodiment of the protection plate.
The protection plate 3a is composed of a pair of upper protection members 3b and lower protection members 3c, which are obtained by horizontally dividing the protection plate 3 described above into two.

The middle crosspiece 4a of the upper protection member 3a has a
A mountain portion 12 cut at a predetermined angle in a manner that intersects with the
A plurality of protection bars 6a are integrally provided in a grid shape at predetermined intervals.

Also, on the lower protection member 3c, a protection bar 6a having a peak 12 opposite to the peak 12 of the upper protection member 3a is arranged so as to be able to block light by shifting it a certain distance. It is formed.

Note that the upper and lower protective members 3b and 3c are connected by a fixing means such as adhesion, welding, or screwing.

Incidentally, the slope angle of the mountain portion 12 is preferably approximately 45° in order to form a light shielding and water drainage portion 7a.

The shape of the division of the protection plates 3, 3a changes depending on the shape of the frame 1, and in the case of the rectangular frame shown in FIG. 2, the inner corner where the tree is placed is formed at an angle of about 45°.

Further, in the case of the frame 1 shown in FIG. 5, a protective plate 3e deformed in accordance with the shape of the frame 1 is used.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

Since sunlight is blocked from entering the roots of the tree by the shading protrusions, weeds growing around the roots are blocked from light and their growth is inhibited. For this reason, weeds are less likely to grow on the roots of roadside trees, so it is no longer necessary to remove weeds as frequently as in the past.

In addition, since a predetermined water drainage part is formed between the protection rails, there is no problem in water management.

The protection plate is made of a synthetic resin that has impact resistance, weather resistance, tread pressure resistance, fire retardancy, and self-extinguishing properties, so it can prevent fire and damage.

The weight of the protective plate can be reduced, making it easier to transport and install.
It is easy to reinstall and remove after installation, and furthermore, when removing weeds after installation, the protection plate can be easily removed.

Unlike metal protection panels, it does not rust due to paint peeling, etc., and can be maintained and managed in the same condition as when it was manufactured.

Since it can be molded into a color and shape that matches the cityscape, it can be used indoors, hotel lobbies, buildings, houses, etc., and can be installed in a wide range of facilities.

The protection plate is made of a synthetic resin that is flame retardant, tread pressure resistant, and impact resistant, so it will not be damaged even if a heavy object such as a vehicle is placed on it.

Since it can be manufactured for about half the installation cost of one conventional protection panel made of cast iron or steel, the product can be provided at a low cost.
