Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a guard tree for a guardrail that is attached to an existing guardrail.

(Prior Art) Conventionally, a guard rail has been installed as a danger prevention fence on an automobile road by connecting a steel strip having a concavo-convex cross-sectional shape (hereinafter referred to as a beam) between columns.

(Problems to be solved by the invention) However, since the upper end of the guardrail beam is sharply directed toward the sidewalk, it is dangerous for pedestrians, especially on the backside (pedestrian side) of the beam. Mud stains adhered to the dents formed by the unevenness on the surface, which spoiled the appearance.

[Constitution of device]

(Means for Solving the Problems) Therefore, in order to eliminate the above-mentioned drawbacks, the present invention provides a headstock having a convex ridge, one of the headstocks is provided with a joint with a guardrail, and the other is provided. The present invention aims to provide a guardrail headstock characterized in that it is provided with strut joints having scattered particles, bolt joint holes are provided in each joint, and a connecting plate is projected on the side surface of the headstock. .

(Embodiment) One embodiment of the present invention will be described below with reference to the drawings. Dust means that there is a difference between planes, and Koguchi means longitudinal direction. A right-angled side surface is shown, and one embodiment of the present invention will be described below with reference to the drawings. Slopes (2) and (3) are provided on the left and right with a curved top (1) as a ridge. At the edge of (2), a joint (6) conforming to the shape of the vicinity of the edge of the beam (4) (the range from the edge of the beam to the fastening part of the beam joining bolt (5)) is formed. Vertically, the edge of the inclined surface (3) is provided with a dispersion (7) having a difference between the planes, and a column joint (8) is vertically arranged. A bolt penetration hole (9) corresponding to the beam joining bolt (5) is provided, and a bolt corresponding to the beam mounting bolt (10) is provided at the joint (8). Nyuana (11) is provided, the small connecting board (14)
It is a guardrail kasagi which is characterized by having a ridge.

(Operation) When the above-mentioned head board (A) is attached to the guardrail,
The edge portion of the sharply protruding beam (4) can be covered with the inclined surface (2) and the joint portion (6), and the headboard having the curved top portion (1) can form a safe handrail without corners. The beam (4) is connected in front of the column (12) by overlapping one end of each beam, and the beam coupling bolts (5) are used to join the beam (4) to the beam (4). )
Is fixed by using a beam mounting bolt (10) with a bracket (13) interposed. Since the bolt penetration hole (9) formed in the joint portion (6) of the headstock (A) is provided at a position corresponding to the beam joining bolt (5), the beam joining bolt (5) is used. The joint portion (6) which is one end of the headstock (A) can be fastened to the edge portion of the beam (4). Since the bolt penetration hole (11) drilled in the strut joint (8) which is the other end of the headstock (A) is provided at a position corresponding to the beam mounting bolt (10), the beam mounting bolt (10) is Use the strut joint (8), which is the other end of the headstock (A), to strut (1
Can be fastened to 2). As a result, the Kasagi (A) can be attached to the guardrail, but the Kasagi (A) attached does not block the line of sight of a pedestrian from diagonally forward and does not expose the back surface of the beam (4) to the outside. . The skirt member (7) provided at the column joint (8) is for preventing the beam mounting bolt (10) from projecting to the sidewalk side, and particularly has a role of blocking the mud splash from the roadside side below. May be additionally spliced at this position and laid vertically.

It should be noted that it is not necessary to form the bolt penetration hole (9) in the headstock connected between the headstocks (A) attached to the respective columns (12),
A connecting plate (12) protruding from the small end is used to screw and connect the successively engaged portions with a screw or the like so as to continuously fix the headstock.

[Effect of device]

According to this invention, since the existing guardrail can be used to immediately install a guardrail headstock, the danger of protruding edges can be easily prevented, and it can be effectively used as a handrail, and also a beam that easily adheres to dirt. You can cover the back side to arrange the aesthetics, and since the Kasagi itself has a convex ridge, even if mud stains adhere to it, it will be washed off naturally due to wind and rain, leaving the mud stains and spoiling the aesthetics. The effect that there is no.
