Abstract

(57) [Summary] [Problem] To improve the transparency and greatly increase the strength by using a small diameter tree such as thinned wood, which has a simple structure and is less usable, and further using metal pipes and screws. Improve,
It is still another object of the present invention to provide a fall prevention fence in which the tip of the pillar is protected and durability is improved. SOLUTION: The fall prevention fence of the present invention is composed of a number of wooden columns arranged at equal intervals on the side of a sidewalk, a wooden handrail shade mounted on the columns so as to cover an upper cut end of the columns, And a metal crosspiece that divides the steel into multiple stages. In addition, the wooden columns and the wooden handrails are made of small-diameter trees such as thinned wood. Further, the metal crosspiece is formed from a carbon steel pipe for piping.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a fall prevention fence installed on a sidewalk such as a road along a mountain stream where a person may fall.

[0002]

[Prior art]

 Conventionally, a fall prevention fence using only wood has the characteristic that a natural texture can be obtained. However, since the material is thick, the transparency is poor and the whole is heavy. In addition, the fall prevention fences made of timber could not penetrate the pillars because the crossbars had to be made thicker in terms of strength, and the strength of the crossbar joints was weak. In addition, the fall prevention fence using only wood had to use thick columns to secure the strength of the joints, which made it difficult to arrange handrails.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention uses a small-diameter tree, such as thinned wood, which has a simple structure and is less usable, and further uses metal pipes and screws to improve the transparency and greatly improve the strength. In addition, the purpose is to provide a fall prevention fence with improved durability by protecting the entrance of the pillar.

[0004]

[Means for Solving the Problems]

 For this purpose, the fall prevention fence of the present invention is composed of a number of wooden pillars arranged at equal intervals on the side of the sidewalk, a wooden handrail shade placed between the pillars so as to cover the upper lip of the pillar, and the gap between the pillars. It consists of a metal crosspiece that partitions in multiple stages. In addition, the wooden pillars and wooden handrails are made of small diameter trees such as thinned wood. Further, the metal crosspiece is formed from a carbon steel pipe for piping.

【Example】

 Hereinafter, a fall prevention fence according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the fall prevention fence of the present invention is composed of a pillar 2 made of small-diameter wood such as a thinned timber with a diameter of 120 mm arranged in a large number at equal intervals on a concrete foundation 1 provided on the side of the sidewalk. A handrail cap 3 made of a small diameter tree such as a thinned timber of 150 mm in diameter and placed between the columns 2 so as to cover the upper cut-out, and a crossbar 4 formed of a carbon steel pipe for piping that partitions the columns 2 in multiple stages. And consisting of

As shown in FIG. 2, one-third of the pillar 2 is inserted into a pillar hole 5 formed in a concrete foundation 1 provided on the side of the sidewalk, and sand 6 is pressed around the pillar 2. Then, the upper part is closed with asphalt and mortar 7.

As shown in FIG. 3, a short connecting pipe 9 made of a carbon steel pipe for piping is inserted into a horizontal hole 8 reaching the center in the transverse direction up to 2/3, and the supporting column 2 arranged at the start end or the end is inserted into the short hole. A horizontal rail 4 made of carbon steel pipe for piping is externally fitted to one-third of the connecting pipe 9, and the horizontal rail 4 is fixed to the short connecting pipe 9 with a stainless steel screw 10 with a locking nut penetrating vertically. Is done.

As shown in FIG. 4, the column 2 disposed in the middle is fitted with a long connecting pipe 12 made of a carbon steel pipe for piping so that both ends project into a through hole 11 penetrating in the transverse direction. The horizontal rail 4 is fitted on both protruding ends, and the horizontal rail 4 is fixed to the long connecting pipe 12 by a stainless steel screw 10 with a locking nut which penetrates up and down.

As shown in FIG. 5, the handrail cap 3 and the handrail cap 3 are joined by shaving a cut end made of a small-diameter tree such as thinned wood, and fitting both the handrail caps 3 provided with a step in a butt shape. And fixed with a short coach screw 13. The connection between the support 2 and the handrail 3 is formed by forming a notch 14 on the lower side of the handrail 3 into which the support 2 fits. The railing coping 3 and the column 2 are connected and fixed by the long coach screw 15 from the upper side of the coping 3. For aesthetic purposes, a blind hole 16 is formed at the place where the coach screws 13 and 15 of the handrail cap 3 are screwed, and the heads of the coach screws 13 and 15 are located at the bottom of the blind hole 16. The upper space is closed by a buried tree 17.

【effect】

 As described above, the fall prevention fence of the present invention uses a combination of wood and metal pipes to enhance the transparency while maintaining the natural texture unique to wood, and to make it lighter as a whole. did it. In addition, the fall prevention fence of the present invention was able to penetrate the column and be continuous by using a metal pipe for the crosspiece, and the strength was greatly improved. In addition, the fall prevention fence of the present invention uses metal pipes for the crosspiece, so that the necessary strength can be obtained even if the strut is made thinner. Protected, durable and enhanced linear fence lines.
