Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a pseudo-wood fence support for a pseudo-wood fence installed in a park, a plaza, a promenade, or the like.

[0002]

2. Description of the Related Art Conventionally, a method of constructing a pseudo-wood fence post of this kind is to use a pseudo-wood fence post in which a pseudo wood-like covering layer made of synthetic resin, concrete or the like is provided on the outer peripheral surface of a core material made of metal or the like. Like, the lower end of the column 8 is buried directly in the ground,
The construction is performed so as to be fixed by the concrete foundation 9 formed in the ground.

[0003]

However, in such a conventional pseudo-wood fence post, since the lower end of the pseudo-wood-like post is directly buried in the ground and fixed by a concrete foundation, the pseudo-wood-like coating layer on the surface of the post is not provided. When it is necessary to replace the support, for example, when the support is peeled or damaged, there is a problem that replacement of the support is difficult and cannot be easily performed. In addition, there is a problem that a concrete foundation must be formed in the ground at the time of constructing the pillar, and the construction tends to be troublesome.

It is an object of the present invention to provide a method of constructing a pseudo-wood fence support which solves the conventional problems.

[0005]

Means for Solving the Problems To solve the above problems, a foundation pillar is driven into the ground while leaving the upper projecting portion above the ground, has an inner diameter larger than the outer diameter of the foundation pillar, and has a wood-like surface. The made pillar body was covered by the ground protrusion of the foundation pillar, which was slightly shorter than the pillar body, to cover and cover the entire ground protrusion, and the pillar body was penetrated by the pillar body and the foundation pillar in the ground protrusion of the foundation pillar. The method is characterized by a method of constructing a pseudo-wood fence post fixed by mounting bolts.

Preferably, the mounting bolt is penetrated substantially perpendicularly to the column main body and the above-ground protrusion of the foundation column, and the mounting bolt head is drilled on the side of the column main body on the head side of the mounting bolt. The bolt hole made larger than the outer diameter of the bolt head is penetrated, and this bolt is further penetrated into the bolt hole of the foundation pillar made smaller in diameter than the outer diameter of the bolt head, and is brought into contact with the edge of the bolt. In addition to pressing the outer surface of the base pillar by screwing, the tip end of the mounting bolt is screwed into a nut portion abutted on the outer surface of the main body of the support column.

More preferably, a fence mounting bracket provided with a nut portion abutting on the outer surface of the column main body,
Attachment is performed simultaneously by using attachment bolts that penetrate and fix the column body and the foundation column.

[0008]

[Function] Since the main body of the support is covered by the ground protrusion of the base pillar having a slightly shorter length than the main body of the support and is fixed to the ground protrusion by the mounting bolt, when the support needs to be replaced, the mounting bolt is required. It can be easily dealt with simply by removing and replacing only the support body. In addition, since the pillar main body is covered on the above-ground protruding portion of the foundation pillar that is driven and fixed in the ground, the construction does not require much work.

The mounting bolt is penetrated through the column body and the foundation column, and the mounting bolt head is penetrated through a bolt hole larger than the outer diameter of the bolt head on the side of the column body on the head side of the mounting bolt. Since this bolt is in contact with the edge of the bolt hole of the foundation pillar having a smaller diameter than the outer diameter of the bolt head which is further penetrated, the bolt is screwed in so as to press the outer surface of the foundation pillar, The pillar body can be firmly fixed without rattling on the foundation pillar.

Furthermore, since the tip of the mounting bolt is screwed into the nut of the bracket for mounting the fence, which is in contact with the outer surface of the column main body, the mounting bolt that penetrates and fixes the column main body and the base column is used. The bracket for mounting the fence can be attached at the same time.

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a pseudo-wood fence post constructed by the method of constructing a pseudo-wood fence post according to the present invention, which includes a foundation pillar 2 that is pre-punched into the ground and a pseudo-wood-like post body 3 attached to the foundation post 2. And is formed from

The base column 2 is usually a metal tube having a circular cross section, and is fixed by being driven into the ground except for the upper protrusion 21 above the ground. The base pillar 2 is usually driven so that about 分 of the total length is buried in the ground, and the length of the above-ground protrusion 21 is slightly shorter than the length of the support body 3. Further, bolt holes 22 for attaching the column body 3 are formed at predetermined plural locations on the side surface of the above-mentioned ground protruding portion 21. The driving length of the foundation pillar 2 is not necessarily limited to the above.

The column main body 3 is formed by providing a pseudo-tree-like coating layer 32 on the outer peripheral surface of a metal tube 31 having a circular cross section or the like having an inner diameter slightly larger than the outer diameter of the base column 2. The pseudo-wood-like coating layer 32 is made of synthetic resin, concrete, or the like, and has a surface having a texture similar to a natural tree. Further, bolt holes 33 for inserting the mounting bolts 4 are formed in a plurality of predetermined places on the side surface of the column body 3. The diameter of the bolt hole 33 on the head 41 side of the mounting bolt 4 is larger than the outer diameter of the bolt head 41 as shown in FIG.

As shown in FIG. 2, the column body 3 is covered by a ground projection 21 slightly shorter than the column body of the base column 2 so as to cover the entire ground projection 21. Further, the mounting bolt 4 is inserted into the bolt holes 33 and 22, and the bolt head 41 penetrates through the bolt hole 33 of the support body 3 having an outer diameter larger than that of the mounting bolt 4. The bolt head 41 is in contact with the edge of the hole 22 through the hole 22, and the bolt tip is pressed against the outer surface of the column body 3 so as to press the outer surface of the base column 2 by screwing in the mounting bolt. The pillar main body 3 is fixedly attached to the base pillar 2 by being screwed into the nut portion 51 of the fence mounting bracket 5.

That is, as shown in FIG. 3, the column body 3 is mounted and fixed to the base column 2 by the mounting bolts 4 and, at the same time, the fence mounting bracket 5 is mounted on the outer surface of the column body 3. As shown in FIGS. 1 and 2, the fence-mounting bracket 5 supports a pseudo-tree beam 6 as a fence. Also, the bolt head 41 of the column body 3
As shown in FIG. 3, it is preferable that the pseudo-wood cap 7 is fitted into the bolt hole 33 on the side so that the bolt head 41 cannot be seen from the outside. Note that a cover or padding may be used instead of the pseudo-wooden cap 7.

[0016]

As described in detail above, the method of constructing the artificial wood fence post according to the present invention is to cover the main body of the post on the above-mentioned protruding portion, which is slightly shorter than the main post body on the upper portion of the foundation pillar, and attach the post to the above-mentioned protruding portion. Since it is fixed by bolts, when it is necessary to replace the column, it can be easily dealt with simply by removing the mounting bolt and replacing only the column body.

Further, since the pillar main body is covered on the above-ground protruding portion of the foundation pillar which is driven and fixed in the ground, it can be constructed without forming a concrete foundation in the ground as in the prior art.
Good workability. In addition, since the pillar main body having the pseudo-tree-like coating layer is not directly driven into the ground, there is no possibility of damaging the pillar main body during construction.

[0018] Further, the mounting bolt is penetrated through the pillar main body and the foundation pillar, and the mounting bolt head penetrates a bolt hole made larger than the outer diameter of the bolt head on the side surface of the mounting bolt of the pillar main body on the head side, As this bolt further penetrates the bolt hole of the foundation pillar made smaller in diameter than the outer diameter of the bolt head, the bolt head comes into contact with the edge, and the outer surface of the foundation pillar is pressed by screwing in the bolt Since it is made, the pillar main body can be firmly fixed without rattling on the foundation pillar. In addition, since the tip of the mounting bolt is screwed into the nut of the bracket for mounting the fence body, which is in contact with the outer surface of the main body of the post, the mounting bolt for fixing the main body of the post and the base pillar is used. Brackets can be attached at the same time, and workability is good.
