Abstract

PURPOSE:To erect a fence so as not to obstruct traffic or spoil scenic views, by falling down the upper posts parallelly to the traveling direction of a road and containing snow shield plates in the summer. CONSTITUTION:A part of a slope at the road side is cut out and base blocks 4 having a L-shaped section are laid down at the part of slope. Main base blocks 5 are placed every several base blocks 4. The vertical part is placed outward and the lower posts 7 are fitted to the steel rods projected to the upper face of the main base blocks 5. The upper posts 8 having a reverse U-shaped form are connected therewith and snow shield plates 10 are fitted between upper support plates 9. During the summer season, the snow shield plates 10 are removed and contained between the lower posts 7. The upper posts 8 removed from the lower posts 7 are contained among the base blocks 4, main base blocks 5, and the lower posts 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow fence device installed on a slope on the side of a road in a snowy region so as not to obstruct traffic. The present invention relates to a snow fence device which is folded in parallel with the traveling direction of the snow box to store a snow plate so as not to damage the scenery.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional snow fence system has a snow fence installed at a position about 30 m on the windward side of the road to prevent snow. Met.

[0003]

With the above-mentioned configuration, the private land must be rented because it is installed at a place distant from the road site. In addition, we install every year in early winter,
The work of removing it in the early spring must be repeated. Therefore, in order to eliminate the troublesomeness, in recent years, as shown in FIG. 7, a blow-off method has been adopted in which a snow fence is installed on the shoulder of the road. Since this method is a permanent installation method, it remains installed even when it is not needed in the summer, and this thing gives pressure to passersby and obstructs the scenery, so fold the snow fence when not needed. Although there are things, the foundations etc. could not be removed and the vehicle could collide with it and cause a serious accident, which also had the disadvantage of hindering the landscape.

[0004]

Therefore, the present invention has been proposed in order to eliminate the above-mentioned disadvantages,
The structure is such that a cutout portion is provided on the side slope of the road, and a basic main block is placed and fixed in that portion between several basic blocks having an L-shaped cross section with the vertical portion facing outward. Attach the lower strut to the reinforcing bar embedded in the block, connect the upper strut to this, and install several snow protection plates between the strut so that the angle can be adjusted.In the summer, remove the snow protection plate and inside the lower strut The upper stanchions can be stored inside the foundation block, foundation main block, etc.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the embodiments will be described with reference to the drawings.
1 is a roadway and 2 is a slope on both sides of the roadway 1. 3 is
The slope 2 is cut out, and a basic main block 5 is interposed between several basic blocks 4 each having an L-shaped cross section, and a large number of them are placed with the vertical portion facing outward. Has a reinforcing bar 6 embedded therein, and an end of the reinforcing bar 6 is protruded above a horizontal portion, and a lower strut 7 of a snow fence is attached to the reinforcing bar 6.
Reference numeral 8 denotes an inverted U-shaped upper strut, which is connected to the lower strut 7 by bolts. Reference numeral 9 is a supporting plate attached to the upper column 8 of the inverted U-shape at appropriate intervals. Reference numeral 10 is a snow protection plate, which is mounted between the support plates 9 and 9 fixed at appropriate intervals on the upper support columns 8 which are erected at regular intervals so that the rotation can be adjusted and the devices can be removed. . In the summer,
The snow protection plate 10 was removed from between the support plates 9 and 9 and housed in the lower strut 7, and the upper strut 8 was housed between the vertical part of the basic block 4 and the basic main block 5 and the lower strut 7 so as to be folded. It is a thing. Reference numeral 11 denotes a cover plate provided on the inner surfaces of the base block 4 and the base main block 5, which is used to store the snow protection plate 10 and the upper support column 8 and then expand the cover to cover them. Reference numeral 12 is a bracket that supports the lid plate 11.

[0006]

Since the present invention has the above-mentioned structure, the road 1
Cut off a part of the slope 2 on the side of the
A base main block 5 is interposed between every several base blocks 4 of the mold, and the vertical blocks are placed outside, and the lower columns 7 are attached to the reinforcing bars 6 projecting from the upper surface of the base main block 5. Inverted U-shaped upper strut 8 is connected to
By attaching the snow plate 10 between the support plates 9 of
It is to be constructed. Then, in the summer, the snow-preventing plate 10 attached between the support plates 9 and 9 is removed and stored in the space between the lower columns 7, and the upper columns 8 removed from the lower columns 7.
The basic block 4, the basic main block 5, and the lower support column 7.
It is intended to be stored between them.

[0007]

As described above, according to the present invention, since the side portion of the road is constituted by the basic block having an L-shaped cross section, the road shoulder can be reinforced and the road can be made strong. Since the snow fence device is installed on the road 1, the land on which the snow fence device is installed is not required and the cost of renting the land is not required. The snow fence device of the present invention is
Other than the winter season, the upper pillars, snow plates, etc. are stored, and when the winter comes, the upper pillars, snow plates, etc. are installed and installed. It can be omitted and construction is easy. Since the equipment of the snow fence device does not protrude on the side of the road, it does not interfere with the passage of vehicles and it is safe without crashing into it and causing an accident. The road shoulders have the effect of improving the scenery.
