JPH11172970A - Foundation block for wooden support of wood fence - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent corrosion due to entry of disinfect from occurring by stopping a direct contact of the outer peripheral surface of a wooden support with the soil through a distance between the upper surface of a foundation block and the ground surface in the foundation block which is buried in an underground and used for installing the wooden support erectedly. SOLUTION: A protective tube part 5 is installed in a communicating state at the entrance of a fixed hole 2 drilled in an upper surface 1a of the foundation block main body 1 used to install the wooden support S erectedly so that it surrounds the outer peripheral surface R of a wooden support S against soil between the upper surface of a foundation block main body 1 and the ground surface G when the foundation block main body 1 is buried in the underground U. Thus its service life is extended because disinfect or the like in the underground U is prevented from entering the wooden support S.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation block for a wooden column such as a wooden fence.

[0002]

2. Description of the Related Art Conventionally, wooden fences are installed mainly in scenic spots or the like so as to match the surrounding natural environment. These wooden fences have wooden posts erected at predetermined intervals, and the wooden posts are installed over a predetermined length by supporting and supporting crossbars. By the way, in order to erect these wooden pillars, as shown in FIG. 6, a fixing hole 101 for inserting the wooden pillar S is inserted through the center of the upper surface in advance to form a concrete base block 100. Then, the base block 100 is disposed in the underground U so that the upper surface 102 thereof is hidden from the ground surface G so as not to impair the aesthetic appearance of the entire wooden fence.
The wooden support S is erected by inserting the lower end of the wooden support S through the base, and covered with soil so that the basic block 100 is hidden. Further, the wooden pillar S is usually subjected to antiseptic and insect repellent treatments, since various germs easily enter the wooden pillar S when the soil comes into direct contact therewith.

[0003]

However, in such a wooden support S, the upper surface 102 of the base block 100 is not provided.
The part T which always comes in contact with the soil between the
In spite of the insect repellent treatment, underground bacteria and the like easily invade and corrode, so that there is a problem that the service life is shortened and a complicated operation of replacing with a new one repeatedly is required. Therefore, the present invention provides a wooden support base block such as a wooden fence that can prevent corrosion from occurring and extend its life by protecting the portion of the wooden support buried in the ground from coming into contact with the soil. It is intended to provide.

[0004]

According to the present invention, there is provided a foundation block for a wooden column such as a wooden fence according to the present invention.
A fixing hole for inserting a wooden post into the upper surface of the basic block main body is formed in the upper surface of the basic block main body, and at the entrance of the fixing hole, the upper surface of the basic block main body and the ground A protective cylinder is provided to protrude the outer surface of the wooden column between the surface and the wooden column so as not to touch the soil. In this way, the wooden column is protected by the protective tube portion from touching the soil, and the wooden column is less likely to be corroded by germs and the like in the ground.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a base block for a wooden column such as a wooden fence according to the present invention. In FIGS. 1 and 2, reference numeral 1 denotes a basic block main body formed into a rectangular parallelepiped by concrete. A fixing hole 2 having a circular cross section for inserting a wooden post S described later into the center of the upper surface 1a of the basic block main body 1 is blind. It is drilled like a hole. A drain hole 3 is formed through the bottom surface of the fixing hole 2.

A pipe member 4 having substantially the same diameter as the fixing hole 2 and having both ends opened is embedded in the fixing hole 2. The pipe member 4 is set so that the upper end protrudes upward from the upper surface 1a of the basic block main body 1 by a predetermined length, and a portion protruding from the upper surface 1a of the basic block main body 1, that is, the fixing hole 2
The upper portion is a protective cylinder portion 5. The pipe member 4 is a steel pipe or a plastic pipe, and is inserted into concrete when the base block body 1 is formed to be integrally formed. In addition, the fixing hole 2 and the pipe member 4 are not limited to a round shape, and may be formed in a square shape according to the shape of the wooden pillar S to be inserted. Further, in place of the pipe member 4, a protective cylinder 5
Can be formed integrally with the basic block main body 1.

As shown in FIG. 3, the base block B is buried and installed in the underground U such that substantially the upper half of the protective cylinder 5 projects above the ground surface G. Then, as shown in FIG. 4, the lower end of the wooden column S is inserted into the fixing hole 2 from the upper end opening of the protective cylinder 5. Next, the gap between the outer peripheral surface of the wooden column S and the inner peripheral surface of the pipe member 4 including the protective tube portion 5 is filled with asphalt filler f to fix the wooden column S. In this way, a plurality of wooden posts S are erected, and the wooden fence F is constructed by mounting and fixing a crosspiece b between the respective wooden posts S, S as shown in FIG.

In the thus constructed wooden support base block B of the present invention, the outer peripheral surface R of the wooden support S between the upper surface 1a of the base block main body 1 and the ground surface G is protected by the protective cylinder portion 5, and Even when buried in the middle U, there is no direct contact with the soil, so that no germs or the like enter, and therefore, corrosion hardly occurs.

[0009]

As described above, in the base block for a wooden column such as a wooden fence according to the present invention, the portion of the wooden column buried in the ground is surrounded by the protection cylinder projecting from the upper surface of the basic block main body. Because it does not directly touch the soil, the wooden pillars are less likely to corrode due to the invasion of germs and the like in the ground, and their life is extended, and there is no need to repeat the complicated work of replacing them with new ones as before. Has an effect.
