As the connection fitting at the lower end of the antiseptic logs 6a, 6a for stays, for example, as shown in FIG. 10, it has a plate 7b fixed by welding or the like so as to cross the bottom of the short steel pipe 7a. Alternatively, the lower edge of the plate 7b is fixed to the steel pipe 1a in advance by welding. A bolt insertion hole 70 orthogonal to the axis is provided at an intermediate portion of the short steel pipe 7a.
In this case, no connection fitting is attached to the lower end of the stay antiseptic log 6a, and the lower end of the log is directly fitted in the short steel pipe 7a, and a perforation that matches the bolt insertion hole 70 is provided. And is fixed by screwing with a nut.
[0024]
In the present invention, an antiseptic log is preferable, but in some cases, some of the plurality of cylinders may be a steel pipe, FRP pipe, a composite of a steel pipe and FRP, a composite of a steel pipe and an antiseptic log, or the like. It is good also as a member of.
[0025]
[Effect of the embodiment]
The operation of the avalanche-preventing suspension frame according to the present invention will be described. In the mountain-side antiseptic treated logs 2a and 2a, connecting fittings 9 and 9 are externally fitted and fixed in advance in the middle. Since the connection fittings 3 and 4 and the connection fittings 7 and 7 are fixed to the bottom body 1 in advance, the mountain side antiseptic treatment logs 2a and 2a are fitted to the short steel pipe 3a of the connection fitting 3 and the valley side antiseptic treatment logs 2b and 2b. Is fitted in the short steel pipe 4a of the connection fitting 4, and is established in an inclined shape so as to automatically form a triangular pyramid. Therefore, if the connecting metal fitting 5 is fitted to the upper ends of the aggregated mountain-side antiseptic logs 2a, 2a and the valley-side antiseptic logs 2b, 2b, a firm triangular pyramid is formed.
Next, the stay antiseptic logs 6a and 6a having the connection fittings 8 and 8 attached to the upper and lower ends respectively in advance are diagonally arranged, and the lower end connection fitting 8 is connected to the connection fitting 7 of the bottom body 1 and the upper end. What is necessary is just to connect the connection metal fitting 8 of a part to the connection metal fitting 9 of the intermediate part of the mountain side antiseptic processing log 2a.
The above operations are simple and the process is simple, and a large number of groups can be easily created.
[0026]
At the time of installation, the bottom body 1 is arranged on the slope, the anchor A is fixed above the slope, and a connecting metal, for example, a shackle C, at the tip of the suspension rope B lowered from the anchor A is connected to the bottom body 1. What is necessary is just to connect with the metal fitting 1d.
FIG. 12 shows a state where the ground is installed in a place where the soil is sandy, and each avalanche prevention suspension frame D is supported by an anchor A provided at a certain level, for example, a suspension line B from a pipe anchor.
FIG. 13 shows a state where the ground is installed at the place of the rock, and each avalanche-preventing suspension frame D is supported by an anchor A provided at each stage, for example, a suspension line B from a pipe anchor.
[0027]
In the installed state, the mountain side where the snow load is mainly applied has two antiseptic logs 2a, 2a, which are supported from the back by stay antiseptic logs 6a, 6a extending from the bottom body 1 made of rigid steel pipe. Therefore, it is possible to reliably support the snow, and since it has a triangular pyramid shape as a whole, the sliding movement of the snow can be prevented.
[0028]
After the snowfall period, the avalanche prevention suspension frame D is the antiseptic log 2a, 2a, 2b, 2b, 6a, 6a whose main member has a cylindrical shape, and therefore a large number of avalanche prevention suspension frames D are arranged. The natural softness and columnar shape of the woody system gives it a natural feel, and when viewed from a mountain on the opposite bank, a driver or a pedestrian who passes nearby, It won't give you a feeling of oppression or intimidation, or damage the beauty or landscape.
Moreover, since the main component is antiseptic logs, it is possible to effectively use cutting roots and thinned wood, conserve resources, and when it becomes obsolete due to aging, it becomes a log by removing it from the connection bracket. Even if it is left as it is, it decays and returns to the soil, so it is environmentally friendly and easy to dispose of.
[0029]
In addition, the bottom body 1 that is in contact with the ground that is constantly exposed to moisture is not made of antiseptic logs, and is made of steel pipes 1a, 1a, 1a ', thereby suppressing the shortening of life due to corrosion. Since the bottom body 1 is covered with weeds and earth and sand, it does not stand out and does not impair the landscape.
The antiseptic logs 2a, 2a, 2b, 2b, 6a, 6a as support members for the mountain side, the valley side and the stay are assembled by being fitted to the connection fittings 3, 4, 5, 7, 8, 9 respectively. Therefore, when these antiseptic logs have partially corroded, they can be regenerated by removing only them from the connection fittings and replacing them with new antiseptic logs.
[0030]
