BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence connection structure, and more particularly, to a fence connection structure having improved assemblability and safety.

The fence may include a plurality of vertical columns fixed at predetermined intervals along the boundary of the ground and a horizontal member connecting the vertical columns so as to clearly separate the boundaries of the ground and perform a protective function. have.

In recent years, a prefabricated fence is often used in which a vertical column and a horizontal member are partially welded or a horizontal member is partially fastened to a vertical column using a piece nail or the like. For example, a fence can be realized by connecting a piece band on a fixing band which is connected to a horizontal member while partially covering the side surface of the vertical column and which is in contact with the horizontal member and the vertical column.

On the other hand, the vertical column and the horizontal member included in the fence may be joined to each other by separate metal bolts and metal screws. By joining these metal bolts and metal screws, the coupling between the vertical column and the horizontal member can be made firm.

However, in the case of a prefabricated fence installed for a boundary between children's play facilities and children's play facilities that are frequently contacted by children or residents' exercise facilities that users can easily touch, such metal bolts and metal screws are projected from the vertical posts and horizontal members, May be injured by metal screws or piece nails.

Further, when the user hits the fence, there is a problem that the rigid horizontal member or the vertical column of the fence may be damaged, or a large impact may be applied to the user's body. Further, unlike the metal fence, the wooden fence structure that can be easily assembled while improving the safety by mitigating the impact by using the wooden fence has a limit not disclosed.
