Description

[0001]
BACKGROUND OF THE INVENTION
The present invention protects people, vehicles, buildings, trees, and the like from snow and sand carried by the wind and the wind, or waves, wind protection, wind protection, snow protection, sand protection, etc. It is related with the perforated plate for a fence used for the fence installed for the purpose of.
[0002]
[Prior art]
A conventional perforated plate for a fence has a large number of punched holes formed in a plate body such as a folded plate or a flat plate.
For example, in Japanese Utility Model Laid-Open Nos. 61-32358 and 61-45413, through-holes having various shapes such as a circle, a triangle, a quadrangle, a rhombus, and an ellipse are provided on the entire surface of the bent plate, and Japanese Patent Application Laid-Open No. 2002-89086. Discloses a slit-shaped through hole.
[0003]
[Problems to be solved by the invention]
The conventional perforated plate for fences is configured as described above, and when the wind passes through the punched hole of the perforated plate, the folded plate changes its direction and collides to become turbulent, and on the flat plate, at the peripheral edge of the punched hole. Turbulent and decelerated, this reduces wind pressure, protects people, buildings, trees, etc. from snow, sand, or splashes carried by waves, winds, and winds, and ensures safe driving of vehicles, etc. .
[0004]
However, because it has a through-hole, for example, waves may enter the road side from the through-hole, which may impair the safety of vehicle traffic, close the vehicle window, and if it is a non-through hole, Or a feeling of obstruction.
The present invention intends to provide a perforated plate for a fence that further enhances the shielding measures and wind reduction effect of such a conventional perforated plate for a fence, and also considers air permeability and transparency. is there.
[0005]
[Means for Solving the Problems]
The invention of claim 1 has a number of holes in a plate, through hole is one short side of the oblong rectangle excising the non-cut portion is formed by Okoshiori the one short side as a base end In addition, the bent tongue piece is provided so as to cover the through hole so as to ensure transparency and at a distance from the through hole surface except for a part of the through hole. .
[0006]
The tongue piece also has a shielding action by the tongue piece, and has the entire shielding action of the fence despite having the penetration hole. Also, the wind blowing in the direction of passing through the through-hole collides with the tongue piece before or after passing, changes direction and collides with each other to become turbulent flow, and the wind speed is attenuated. Because it is different from the wind turbulence generated by collision with the surface (the one with the conventional perforated plate), these two turbulences combine to form a more complicated turbulent flow and further wind speed damping action occurs. is there.
As a result, waves, snow, sand, etc. that are carried by the wind and collide with the fence are prevented from passing directly through the through hole, and the momentum scattered by the wind speed is reduced, for example, through the through hole. Passed waves and so on fall near the fence.
[0007]
In addition, the tongue piece covers a part of the through-hole and is spaced from the through-hole surface, so that a part of the front surface and at least a see-through property from an oblique direction are recognized, and air permeability is also provided. As a result, the driver and passengers of the vehicle do not have a feeling of blockage, and the scenery can be enjoyed and adapted to the environment.
[0008]
A cut portion for forming a through hole is provided with a non-cut portion, and the cut portion is bent to one surface of the plate with the non cut portion as a base end to form a tongue piece. The tongue piece is formed by utilizing the part to be excised to form the shape.
[0009]
According to the invention of claim 2, the tongue piece is provided on one plate surface, and the surface on which the tongue piece is provided can be arbitrarily determined and installed on the leeward side or leeward side.
In the invention of claim 3, the tongue piece is provided on both plate surfaces, and in the invention of claim 4, the tongue piece is provided separately on one plate surface and the other plate surface of the through hole. It is a thing.
[0010]
The invention of claim 5 is such that the tip of the through-hole covering portion of the tongue piece is formed in parallel with the through-hole surface, and even if the tongue piece is parallel to the through-hole surface (plate surface), Because of the positional relationship, a time difference in which the wind collides occurs, and a complicated turbulent flow is generated.
[0011]
In the invention of claim 6, the plate is a bent plate, and the turbulent flow generated on the bent surface of the plate and the turbulent flow of the tongue piece are different from each other. The effect can be expected.
[0012]
