Therefore, since the entire amount must be disposed of and re-installed, there is a problem in terms of safety and durability as well as economy. Moreover, because outdoor facilities are mainly made of soft wood such as Rikumatsu (a kind of pine) or Mimatsu (a kind of pine), they are exposed to wind and rain in the open air and decay due to seasonal changes. There is a problem in that the binding site such as the rope and the pipe breaks and the safety and aesthetics are impaired.

The present invention is to solve such a problem, and its purpose is to process a groove in a connecting portion of general wood and hard wood and connect them at right angles to each other, and then form a fastening recess in the connecting portion. By connecting the fastening band, the deformation due to the elasticity of the wood is prevented, the durability and adhesion are improved, and the binding force with the wood pillar is improved. An object of the present invention is to provide a wood pillar connection structure for outdoor facilities that can prevent corrosion of the connection part.

Another object of the present invention is to provide a wood pillar connection structure for outdoor facilities that can prevent damage due to cracks in the wood pillar corners and external surfaces by installing protective caps at the top and bottom of the wood pillar. Is to provide.

In order to achieve the above-mentioned object, the present invention is formed in a square or circular rod shape with hard wood, fixedly installed on the ground, a coupling groove is suspended in the center of the upper surface, and a square or circular fastening is provided on the outer periphery of the upper end. A lower pillar with a recess, an upper pillar that is formed of a soft wood into a square or circular rod shape, and has a projection protruding to join with a coupling groove of the lower pillar at the center of the bottom, and metal or synthetic resin It is formed in a square or circular belt shape, and is fastened to a fastening recess of the lower column to fasten and fix the lower column and the upper column, and is made of metal or synthetic resin, and is fitted on the upper end of the upper column And a lower protective cap made of metal or synthetic resin and fitted on the lower end of the lower pillar.

In addition, a first rope hole penetrating horizontally through the fastening recess of the lower column is formed, and a second rope hole corresponding to the first rope hole is formed in the fastening projection of the upper column, A rope penetrating the first rope hole and the second rope hole is further provided.

In addition, when the lower column and the upper column are in the shape of a square bar, the fastening band has a fastening plate with first bolt holes at both ends vertically bent inward, and the hemispherical first leaves are equally spaced. A U-shaped body that is provided in the width direction and has a third rope hole through which the rope penetrates; a second bolt hole that is coupled to the fastening plate of the body is formed at both ends; A rectangular plate-like coupling plate in which a second rope is provided in the width direction at equal intervals and a fourth rope hole through which the wooden rope passes is formed.

On the other hand, when the lower column and the upper column are circular rods, the fastening band has first bolt holes formed at both ends, and hemispherical first leaves are arranged at equal intervals in the width direction, and the rope A semi-annular first body in which a third rope hole is formed, through which a second bolt hole is formed at both ends, and hemispherical second leaves are provided at equal intervals in the width direction, and the rope And a semicircular second body that is coupled with the first body to form a circular shape, in which a fourth rope hole is formed.

According to the wood pillar connection structure of an outdoor facility according to the present invention having the above-described structure, after a groove is formed in a connection portion of general (soft) wood and hard wood and connected perpendicularly to each other, a fastening recess is formed in the connection portion. By connecting the fastening band, the deformation due to the elasticity of the wood can be prevented, the durability and adhesion can be improved, and the bonding force with the wood pillar can be improved. It is possible to prevent the corrosion of the connecting part with the wood column and to prevent damage due to cracks of the wood column corner and the external surface by installing protective caps at the top and bottom of the wood column. is there.
