処分のための支出もかさむこととなる。As is well known, it is necessary for the road guide sign tower to recognize the displayed contents even from a considerable distance from the inside of a moving vehicle. Since a smooth flow may be impaired, it is necessary to suspend a considerably large signboard at a considerable height. Therefore, in Japan, a typhoon-prone country, if the sign tower with the above-mentioned structure is to withstand strong winds and is to be stably buried in the ground, a considerably large burial hole as described above is dug up, and in addition,
It is difficult to ignore the cost of placing concrete, and also the cost of disposing of the remaining soil.

案内標識塔を提供することを目的とする。Even if a strong sign tower is buried to such an extent that it will not fall over even if it is subjected to strong wind pressure, if it is attempted to reliably prevent the danger that the sign board part is blown off by an abnormally strong wind, the sign tower itself will be destroyed. Spending to improve strength will also increase. The present invention is provided with means for attaching a sign plate and an arm part capable of receiving the strong wind pressure when it receives a strong wind pressure, which simplifies the underground burial structure of the sign tower and also provides a comparison. The purpose of the present invention is to provide a road guide sign tower that has a light structure and is not damaged even if an abnormally strong wind is encountered.

To be
In the case of a relatively strong wind pressure below a set level that does not allow the arm to rotate, due to the force-force relationship between gravity and wind pressure that keeps the sign plate in the hanging position, the sign plate reduces its pressure receiving area to prevent wind. It is swung toward the leeward side by wind pressure so as to be carried away. The means for attaching the sign plate and the arm part is to adjust the number of screws, the mounting position, the shape and size of the surface where the screw presses the arm and the tightening torque of the screw to limit the rotation of the arm part depending on the situation. The wind pressure can be adjusted as desired . This ensures that the installation topography of the road information sign, weather conditions, the shape of the sign board, depending on the size and the like, the maximum wind speed appropriately pole is rotated from time to time, very precisely and easily to a free value even after installation Can be set. Therefore, the maximum wind speed may be set incorrectly for the buried structure in the middle of the pole.
There is no need to have a safety margin for the difference, and it can be made more compact and the burial cost can be greatly reduced.

As shown in FIG. 4, after the top end portion 1a of the pole portion 1 is fitted into the inner hollow portion b of the cylindrical lower portion 3a of the rotary joint portion 3 welded to the lower end of the arm portion 2, the bolt 4 is inserted. It is done by tightening with a torque wrench. Therefore, when the arm portion 2 is simply fitted into the pole portion 1, the arm portion 2 can freely rotate about the pole portion 1 as a rotation supporting shaft, and if strong wind pressure is exerted on the sign plate 5. The arm portion 2 naturally rotates in the leeward direction in which the wind pressure received by the sign plate 5 is minimized.

ずる。However, if the sign plate 5 is easily displaced in a direction different from the traveling direction of the automobile even with a slight wind force, it will no longer function as the sign plate 5, so that the bolt 4 is screwed in so that the arm portion 2 is poled. It is provided by a mounting method in which the portion 1 is pressed and locked. However, in Japan, which is a typhoon-stricken country and is exposed to strong seasonal winds in the winter, sufficient consideration must be given to the danger of falling of the signboard due to strong winds and the danger of being blown away by the wind. I won't. If the burial hole A is made sufficiently large as a measure for preventing the sign tower from toppling over, the construction cost will be greatly increased, and depending on the conditions of the installation site, it may be difficult to construct.

When the wind pressure above the set level is exerted on the sign plate 5 so that it can rotate in the leeward direction with respect to the pole portion 1 and does not easily rotate even if it receives a relatively weak wind. The rotational torque generated in the arm portion 2 by the wind pressure exceeds the tightening pressure by the bolt 4, the arm portion 2 rotates in the leeward direction, and the wind pressure exerted on the sign plate 5 is received.

る。In order to rotate the arm portion 2 only when the wind pressure of a certain set level, for example, the wind pressure of 30 m / sec or more, is received, the number of bolts 4 to be mounted, the mounting positions, It is necessary to experimentally obtain necessary data on the shape and dimensions of the surface where the bolt 4 presses the arm portion 2 and the related factors such as the tightening force of the bolt 4.

常な取付け位置に固定される。In order to avoid the inconvenience that the pressure contact surface between the tip portion of the bolt 4 and the pole portion 1 is corroded and the frictional engagement force between the two is changed over time, the bolt 4 is made of a corrosion-resistant material. It is desirable to make the above or to interpose a corrosion resistant material layer 60 of synthetic resin or the like at this contact interface. The intervening material layer 60 also prevents the pole portion 1 from being damaged by the tip of the bolt 4 when the arm portion 2 is rotated by a strong wind. After the wind has subsided, the arm part 2 that has rotated in the leeward direction due to a typhoon or a gust of wind loosens the bolt 4 and returns to the original position, and then again tightens the bolt 4 with a predetermined tightening pressure using a torque wrench or the like. By re-loosing it, it will be fixed in the normal mounting position.

が発生することが防がれている。In the above, the sign tower, for example, has a wind speed of 30 m / se.
This is a countermeasure against the case where a wind pressure above a set level such as c is exerted, but if a structure is given that the wind pressure exerted on the sign tower is received even when a relatively strong wind below this set level is received, the pole It becomes possible to reduce the embedding hole A of the portion 1. Therefore, in the sign tower of the first embodiment of the present invention, the sign plate 5 is attached to the arm portion 2 via the hinge-like connecting portion 10. As shown in FIGS. 5 and 6, a pair of bearings 17 are incorporated in the hinge-shaped connecting portion 10 to reduce rotational friction, and the sign plate 5 vibrates under the pressure of pulsating wind. It prevents the generation of unpleasant noise.

Therefore, the connecting pin 11 of the hinge-like connecting portion 10 is provided with an appropriate spring for controlling the rotation of the sign plate 5. It is desirable to install a coil spring or leaf spring having an acting force.

ばされる恐れはほとんど解消させられる。Regarding the sign tower of the present invention constructed so as to receive the wind pressure exerted on the sign plate 5 in this manner,
As mentioned above, the pole part 1 has a diameter of about 13 cm and a total length of about 6 cm.
A comparison test was performed with a conventional sign tower with approximately the same geometry of m. As a result, the burial hole A'has a depth of about 1.2 m,
The cross section of the hole A'is approximately 0.8 to 1.0 in the direction parallel to the signboard 5.
m, the diameter direction is about 1.3 m, and the volume is about 1,200 ~
While it required a size of 1,500 liters,
Although the depth of the embedding hole A according to the present invention is about 1.2 m, the cross-sectional dimension thereof is about 0.5 m × 0.5 m,
The capacity of the hole A is about 300 liters, which is 1/4 to 1/5 of the conventional one.
It was confirmed that the size is enough, which is an extremely convenient facility for burying the sign tower. Further, even if an abnormally strong wind is encountered, the danger of the recognition tower tipping over and the signboard 5 being blown off can be almost eliminated.
