Description

[Detailed Description of the Invention] This invention relates to an improvement of fence materials for guardrails installed along roads to protect pedestrians and automobiles.

Conventional guardrails are formed by attaching fence materials made of steel plates or steel pipes to pillars, which poses a safety problem for pedestrians and automobiles. For this reason, it is possible to use wood such as logs as the fence material, but in this case, it is said that it would be easily damaged by a collision with a car, etc., and would be cut and taken away for use as firewood, etc. There were flaws.

This idea was made to eliminate the above-mentioned drawbacks, and it is a guardrail that is sufficiently safe for pedestrians and cars, is strong against impact, and can prevent it from being cut and taken away. The purpose is to provide fencing materials for That is, this invention is a fence material that is attached to pillars erected at predetermined intervals, and is a log material in which slits extending from the outer periphery in the direction of the tree center are formed over the entire length;
It consists of a strong linear body stretched between the above-mentioned supports, and the linear body is inserted into the slit of the log material and penetrated in the length direction of the log material.

Embodiments of this invention will be described below with reference to the drawings. FIG. 1 shows a guardrail fence material 1 according to this invention. This fence material 1 is
It is composed of a log material 2 formed by peeling the bark of a log and shaving it into a substantially uniform cross section, and a strong linear body 3 made of wire rope, steel wire, or the like. A slit 20 extending from the outer periphery toward the tree center is formed in the log 2 over the entire length, and the linear body 3 is inserted into the slit 20 and penetrates through the log 2 in the length direction. has been done.

As shown in FIGS. 2 and 3, this fence material 1 is attached via attachment members 5 to support columns 4 that are erected at predetermined intervals. As shown in FIG. 4, this mounting member 5 is formed into a cylindrical shape having an insertion hole 50 through which the log material 2 is inserted, and a slit 51 of a predetermined width is formed below the insertion hole 51 over the entire length. Attachment holes 52, 52 for material fixing bolts are formed, and an attachment hole 53 for attachment bolts to the support column 4 is formed on the side of the intermediate portion. With the side end of the log 2 inserted into the insertion hole 50 of the mounting member 5, the tip of the mounting bolt 21 is inserted into the support 4.
By passing through the hole and tightening the nut 22,
The log material 2 is attached to the support column 4 with its side end portion held by the attachment member 5. Also,
The linear body 3 is stretched by having its side end portions locked to the mounting bolts 21 of the terminal struts 4'.
By tightening the mounting bolt 21, the log material 2 is compressed through the mounting member 5, the gap between the slits 20 is narrowed, and the log material 2 is held in a state where it bites into the material. Further, the side ends of the logs 2 are fixed by fixing bolts 23 screwed into the mounting holes 52 of the mounting member 5, and rotation and movement of the logs 2 are reliably prevented, and the logs 2 are fixed to the mounting members 5.
It is designed to be firmly held.

Incidentally, a bracket is provided on the above-mentioned terminal support 4', and the side end portion of the linear body 3 is fixed to this bracket in advance and the linear body 3 is stretched.
After fitting the slit 20 of the log material 2 onto the outside and dropping the log material 2, the side end portion of the log material 2 may be inserted into the insertion hole 50 of the mounting member 5 and held therein.

Since the outer periphery of the fence material 1 constructed as described above is covered with the log material 2, it gives a soft impression and will not cause serious injury even if a pedestrian or bicycle collides with it. There is an advantage. Furthermore, since the log material 2 is reinforced by the strong linear body 3, it is strong against impact, and even if a car collides with it, the fence material 1 can be prevented from being damaged to pieces. can.
Furthermore, since the log material 2 has a slit 20 formed therein, by fitting the slit 20 onto the linear object 3, the linear object 3 can be easily penetrated through the log material 2. This slit 20 has the advantage that the log material 2 can be prevented from drying and cracking. Furthermore, if the log material 2 is damaged due to a car accident or the like, it is possible to replace the damaged log material 2 with a new one while other log materials 2 and linear bodies 3 are installed. , can be restored very easily. Further, even if an attempt is made to cut the log material 2 with a saw or the like, since the linear body 3 penetrates through the log material 2, it cannot be easily cut, and it is possible to effectively prevent the log material 2 from being carried away as firewood.

Note that the log material 2 does not necessarily need to be rounded, but as in the above embodiment, it is rounded so that it has a substantially uniform cross section, and its outer diameter is set by the mounting member 5.
If the hole is formed to be slightly smaller than the insertion hole 50, the log material 2 can be easily inserted and held firmly. Further, the structure of the attachment part of the fence material 1 to the pillar is not limited to the above embodiment, and various modifications are possible. For example, as shown in FIG. 5, one side part is hinged 60. The mounting member 6 may hold the side end of the log 2, or the side end of the log 2 may be directly bolted to the support 4.

As explained above, the fence material according to this invention is composed of a log material with slits and a strong linear body inserted into the slits, and is resistant to pedestrians and bicycles. To provide sufficient safety and to give a soft impression, and to be strong against impact, not to be severely damaged even in the event of a collision with a car, etc., and to prevent logs from drying and cracking. This has the advantage that it is possible to
