Description

  The present invention relates to a guardrail structure.

  Conventionally, by using a natural material to form a guardrail, there has been one using horizontally long wood as a guardrail configured to match a natural landscape.

  Such a guardrail structure has a structure in which a guardrail plate formed of horizontally long wood is installed between support columns standing at a predetermined interval.

  In addition, the guardrail plate has a structure in which a plurality of horizontally long timbers are stacked, and a binding member that binds these horizontally long timbers to each other is embedded in the stacked horizontally long timbers.

  As a result, the laminated horizontally long timbers can be firmly bound, and a stable guardrail plate has been obtained.

  Here, the horizontally long timber is made of wood such as cedar and cedar, cut into a thickness of about 120 mm, a width of about 166.5 mm, and a length of about 4000 mm. It was.

And the structure which fixes this guardrail board to a support | pillar fixed the fixing member of the substantially vertically long rectangular shape to the predetermined position of the support | pillar, and fixed the free end part of each horizontally long timber to this attachment member with the volt | bolt and the nut. The structure was used (see, for example, Patent Document 1).
JP 2003-96736 A

  However, the conventional guard rail does not use the natural wood as a horizontally long timber constituting the guard rail plate, but cuts the timber into a predetermined size, makes one side of the column side flat, and the other side is slab. Since the one formed into a shape was used, the surface of the guardrail plate was a cut surface of wood, and was in an unprotected state against the use environment. Therefore, there is a problem that moisture such as rain or night dew easily penetrates into the wood, and the horizontally long wood is easily deteriorated or spoiled.

  Furthermore, since a plurality of horizontally long timbers are bundled by burying the bundling members for bundling these horizontally long timbers in the stacked horizontally long members, a cut portion is formed inside the horizontally long timbers. There was a problem in that moisture easily penetrated into the horizontally long member from the cut portion, and the progress of deterioration and decay of the horizontally long wood was accelerated.

  In addition, in order to fix the guardrail plate to the column, bolts must be tightened on each horizontally long timber. Again, moisture penetrates into the horizontally long timber from the bolt insertion part, and deterioration of the horizontally long timber There was a flaw that accelerated the progress of corruption.

  In addition, the process from the formation of the guardrail plate to the installation on the support column in this way requires many steps, and there is a problem that the operation is complicated and requires a lot of work time.

  In addition, when laminating horizontally long timber, although one side of the side of the horizontally long timber is a flat surface and the other surface is shaped like a stick, the contact surface between the horizontally long timbers that overlap is minimized. When it rains, water stays in the vicinity of the contact surface for a long time due to the surface tension of the water, and there is also a problem that the progress of deterioration and decay of the horizontally long timber has been accelerated. .

  Furthermore, since the thing which laminated | stacked the wood was used as a guardrail board, there existed a malfunction that a weight was bulky and the load was applied too much to the support | pillar.

Therefore, in the present invention according to claim 1, in a guard rail structure in which bamboo fences are installed between pillars standing upright at regular intervals to form a guard rail on the road shoulder, the bamboo fences are stacked one above the other through bamboo knots. It is constructed so that a certain gap is formed between the bamboo baskets of the overlapping bamboo baskets, and the free ends of the multiple bamboo baskets are attached to the bamboo basket mounting case with a U-shaped cross section that is open on both sides and upwards attached to the column. Inserted and fixed, the upper part of the facing side of the bamboo basket mounting case is drilled with long long holes facing each other on both sides, and the opposing long hole penetrates the side surface facing the bamboo basket mounting case We decided to insert a bamboo shoot suppression bolt and screw it in with a bamboo shoot suppression nut.

  Moreover, in this invention which concerns on Claim 2, the said bamboo basket attachment case used the cross-section H steel which served as the support | pillar.

According to the third aspect of the present invention, in the guard rail structure in which a plurality of bamboo baskets are installed at regular intervals between the columns that are erected at regular intervals, and the guard rails are used as roadside guard rails, It was inserted into the left and right open substantially box-shaped case, and a slit was formed in the front surface of the substantially box-shaped case, and a notch was formed in the center of the front surface.

(1) According to the invention described in claim 1, in the guard rail structure in which bamboo fences are installed between the pillars standing upright at regular intervals to form a guard rail on the road shoulder, It is configured so that a certain gap is formed between the main body of the overlapping bamboo baskets, and the free ends of the plurality of bamboo baskets are attached to both sides attached to the column and the bamboo baskets with a U-shaped cross section open upward Inserted and fixed in the case, the upper side of the side facing the bamboo basket mounting case is drilled with long long holes facing each other on both sides, and the side facing the bamboo basket mounting case in the opposite long hole Since a bamboo fence deterrent bolt that penetrates through is inserted and screwed in with a bamboo fence deterrent nut, it is possible to construct a guardrail with a simple configuration using bamboo, simplifying the construction work and working time Can be shortened.
