Description

  The present invention relates to a gaze guidance mark, and more particularly, to a gaze guidance mark attached to a steel pipe column provided on a side edge of a road.

  The line-of-sight guidance mark is attached to, for example, a head portion or an intermediate portion of a steel pipe column provided on a side edge of a road, and has a function of reflecting the light when hit by a vehicle light. The reflected light causes the driver of the vehicle to grasp the degree of road bending and the road width. That is, the gaze guidance mark is a part for a traffic safety facility that plays a role of gaze guidance for the driver of the vehicle. Here, the steel pipe column includes not only a guard rail that protects a pedestrian from a vehicle, but also, for example, a guard pipe, a fence, a car stop rail column, and the like provided on a side edge of a road.

  FIG. 5 shows an example of a guard pipe provided on the side edge of the road. The guard pipe 20 is formed by connecting steel pipe columns 8 fixed to the ground by an assembly member 26 that is also assembled from steel pipes. The steel pipe column 8 has various types such as Φ60.5, Φ76.3, Φ89.1, Φ101.6, and Φ114.3 depending on the diameter of the steel tube. A cap 9 for closing the inside of the hollow steel pipe column 8 is attached to the head of the steel pipe column 8 by, for example, welding. Generally, the outer diameter of the cap 9 is slightly larger than the outer diameter of the steel pipe column and protrudes from the steel pipe column.

  The main body of the line-of-sight guide provided on the steel pipe column 8 such as the guard pipe 20 is manufactured by, for example, aluminum die casting, steel casting, recycled resin, or the like. In addition, an ultra-high brightness reflection sheet is mounted on the outer wall of the cylindrical line-of-sight guide using, for example, a transparent rivet.

  In general, the line-of-sight guide mark is formed by making a hole in an existing steel pipe column 8 and fixing it with bolts and nuts, or is attached to the steel pipe column 8 using a dedicated bracket. Moreover, when installing a gaze guidance mark in the steel pipe pillar 8, the tool and metal fitting for connecting are required.

  Patent Document 1 discloses a guard pipe protector for a road or the like. Here, a technique for mounting a protective device on a guard pipe in which pipe materials are arranged in parallel along a side edge of a road or the like is described.

JP 2005-54385 A

  In order to install the line-of-sight guide mark on a steel pipe column, some processing must be performed on the existing steel pipe column. For this reason, there is a problem in that it takes time and labor to install the line-of-sight guidance mark, and it is necessary to bring in tools and fittings for that purpose.

  On the other hand, there is a possibility that the line-of-sight guide mark can be easily removed in a configuration that can be easily attached to the steel pipe column. Since the line-of-sight guidance mark is a part for a traffic safety facility, it is a social requirement that the structure is not removed.

  An object of the present application is to solve such problems and provide a line-of-sight guide that can be easily installed without processing the steel pipe column and is not removed from the steel pipe column.

  In order to achieve the above object, a visual guidance indicator according to the present invention is a visual guidance indicator attached to a steel pipe column provided on a side edge of a road, a cylindrical portion on which a reflection sheet is mounted on an outer wall, and one end of the cylindrical portion. Reflective sheet mounting component composed of a circular lid portion connected to the cylindrical lid portion, a concave fitting portion connected to the circular lid portion and projecting into the cylindrical portion, and a cap fitting portion having a circular groove inside A cylindrical insertion portion into which the cylindrical portion is inserted, a semicircular lid portion connected to one end of the cylindrical insertion portion, and a semicircular lid portion of the cylindrical insertion portion that is connected to the outside of the cylindrical insertion portion. A projecting fitting part that protrudes, and two halved fixing parts obtained by halving a steel pipe column fixing part, and the half fixing part combined with the reflective sheet mounting part is The hook-shaped fitting part is locked to the concave fitting part and fitted together, and the cap fitting part is made of steel. Characterized in that it is fixed to the steel column by fitting the cap provided at the upper end of the column.

  According to this configuration, the cap can be fitted by two halved fixing parts that are halved by utilizing the fact that the outer diameter of the cap provided at the upper end of the steel tube column protrudes from the outer diameter of the steel tube column. Thereby, a gaze guidance mark can be fixed to a steel pipe column, and a gaze guidance mark can be easily attached, without adding a process to a steel pipe column. Further, the two half-fixed parts are inserted into the reflective sheet mounting part on which the reflective sheet is mounted, so that the combined half-fixed part and reflective sheet mounted part are integrated. Then, the inserted convex fitting part is engaged with the concave fitting part so that the steel pipe column fixing part and the reflection sheet mounting part are integrated and fixed, and the line of sight is not removed from the steel pipe pillar. It can be a mark.

  Further, the line-of-sight guide mark has a cap fitting portion having an outer diameter larger than the outer diameter of the cylindrical insertion portion, and other than the cylindrical portion inserted by the step of the outer wall generated at the connection portion with the cylindrical insertion portion. It is preferable to abut the ends. As a result, the reflection sheet mounting component has its one end restrained from moving to one side by engaging the inserted convex fitting portion with the concave fitting portion, and the other end of the half fixing component. The movement to the other side is restrained by contacting the step of the outer wall between the cap fitting part and the cylindrical insertion part. From these things, a gaze guidance mark can be reliably fixed to a steel pipe pillar.

  In addition, the line-of-sight guide mark has a wedge that protrudes from the outer wall of the convex fitting portion at at least one location, and the concave fitting portion locks the wedge on the inner wall. It is preferable to have a wedge stop. As a result, the half-fixed component combined with the reflective sheet mounting component is fitted by means of a wedge of the convex fitting portion, a concave fitting portion, and a wedge stopper.

  Further, the line-of-sight guide mark is a rod-shaped member whose wedge of the convex fitting portion is a rod-like member, and the wedge of the concave fitting portion is an inner wall whose inner diameter decreases toward the convex fitting portion to be inserted. A step is preferable. Thereby, the convex fitting part and the concave fitting part are fitted with the rod-shaped member engaged with the step on the inner wall.

  Furthermore, it is preferable that the line-of-sight guide beveled with the length at which the tip of the wedge of the convex fitting portion protrudes in the insertion direction into the concave fitting portion is reduced. Thereby, the rod-shaped member is easily passed through the step on the inner wall and locked.

  As described above, according to the line-of-sight guidance mark according to the present invention, it is possible to provide a line-of-sight guidance mark that can be easily installed without processing the steel pipe column and is not removed from the steel pipe column.
