Description

[Detailed description of the invention] This invention relates to an icicle protection wall within a pig road that prevents icicles from forming within the road and prevents accidents caused by icicles to vehicles passing through the road.

Conventionally, icicle protection walls have been built on roads in cold regions to prevent accidents caused by broken and falling icicles.

However, since these protective walls are mainly constructed on-site, the construction period is long, causing a major hindrance to incoming vehicles, the construction costs are high, and they do not completely prevent icicles from forming. The drawback was that there were many accidents caused by icicles.

This invention eliminates the drawbacks of the conventional ones as mentioned above,
Mainly processed in a factory, it can be easily assembled and constructed on site, significantly shortening the construction period and reducing construction costs, as well as completely preventing the occurrence of icicles and preventing accidents caused by them. The purpose is to provide an icicle barrier within the throat.

This invention will be explained with reference to embodiments shown in the drawings.

1 of the drawing shows the icicle protection wall inside the path, and this protection wall 1
The cover wall 5 includes a plurality of unit frames 2 interconnected through a spacer 3 and a seal 4 which is a watertight member, and this cover wall 5 has anchor bolts 6 which are mounting members. , are attached to the inner wall 9 of the canal 8 at intervals with groove shaped steel 7.

As shown in FIGS. 3 and 4, the unit frame 2 has four edges of a square plate-shaped body 10 made of a metal plate such as an iron plate at the same angle of 45° with respect to the plate-shaped body 10. A vertical edge material 12 for joining is formed by bending the ends of the inclined edges 11 in the same direction at an angle of 90° with respect to the plate-shaped body 10. As a result, a recess is formed inside the unit frame 2.

A plurality of bolt holes 13 are bored at predetermined intervals in the vertical edge member 12, and four overhanging plates extending inward from each other are located outside the bolt holes 13 on the inside thereof. Each side edge of 14 is fixed respectively.

Decorative plates 16 are fixed to these projecting plates 14 with screws 17 to hold a heat insulating material 15 such as glass fiber filled inside the unit frame 2 so that it does not fall.

As shown in FIG. 5, the spacer 3 is formed by bending both edges of a long metal plate 18 in the same direction and at almost right angles to form a rising plate 19 and 19. Board 19
．． The tips of 19 are inclined in the direction of approaching each other,
Further, a plurality of bolt holes 20 are bored in this upright plate 19.19 at intervals equal to the intervals between the bolt holes 13.13.

Then, the vertical edge material 12 of the unit frame 2 is placed on the rising board 19.19.
are in contact with each other with a gasket 4 interposed therebetween, and are tightened with bolts and nuts 21 to prevent water leakage, thereby forming an arch-shaped cover wall 5.

At both ends of the cover wall 5, there are closing frames 23 that close both ends of the space 22 formed between the cover wall 5 and the inner wall 9 of the passageway 8 to prevent cryogenic wind from directly blowing into the space 22. is installed, and this frame 23 consists of a main frame 24 with a U-shaped cross section attached to both ends of the cover wall 5, and a sub-frame 25 attached to the inner wall 9, and the main frame 24 is attached to the sub-frame 25. They are movably fitted, and the inside thereof is filled with a heat insulating material 15.

The base end of the anchor bolt 6 is screwed into an anchor hole 26 drilled at a necessary location in the canal 8, and the spacer 3 is welded and fixed to the tip thereof.

Note that 27 is an anchor bolt for installing groove shaped steel 1.

When assembling the above-mentioned parts, groove-shaped steel 7 is installed on the floor of the passageway 8 in parallel with the inner wall 9 at a predetermined interval, and spacers 3 are installed at the required number of intervals on the upper part of the inner wall 9. Attach via bolt 6 across the two sides.

A large number of unit frames 2 are provided between each spacer 3 and between the spacer 3 and groove shaped steel 7.
At the same time, gaskets 4 are interposed between each unit frame 2 and between the unit frame 2 and the spacer 3 and groove shaped steel 7, and the bolts and nuts 2 are connected to each other.
1 to form the covering wall 5.

Then, a frame 23 is installed at both ends of the cover wall 5, and
The protective wall 1 is constructed by filling the recess of the unit frame 2, the spacer 3, and the frame 23 with a heat insulating material 15, and fixing the decorative board 16 thereto.

In the above, the unit frame 2 is shown as having a square shape, but it may have a rectangular or triangular shape, and the vertical edge 12 for joining is shown as being formed at the tip of the inclined edge 11. However, it goes without saying that the vertical edge members 12 may be directly formed on the four edges of the plate-shaped body 10 without forming the inclined edges 11.

This invention is as mentioned above, and it is possible to construct an icicle protection wall extremely easily by simply connecting a large number of unit frames to each other, and the construction period is greatly shortened. In addition to not causing any major hindrance to the process, construction costs are greatly reduced, making it possible to provide a product that is extremely economical overall.

In addition, the protective wall prevents the inner wall of the den and the spring water from being cooled below the freezing point even if extremely low-temperature wind blows into the groin, and the spring water immediately flows outside the protective wall and flows down into the gutter, forming icicles. This has the excellent effect of completely eliminating accidents caused by entering a vehicle.
