用なものとなる。(Prior Art) In order to prevent accidents or snow damage and ensure safety on roads, and to clarify the boundary at the land boundary, it is common to install columns and fences. However, in this case, it is desirable to be able to freely remove the fence in order to secure the view and scenery when the fence is not used. In particular, the blow-off fence is effective in securing the driver's visibility on road traffic against snowstorms in winter, but is not useful at other times.

た。(Problems to be solved by the invention) However, in the conventional fence strut structure, since the concrete foundation 10 was placed in each case, in order to secure the support strength of the strut 11, a relatively large foundation is required. It was necessary and there was a problem that the foundation could not be installed if there was no room at the boundary of the adjacent land. Further, when trying to secure a view or a landscape when the fence is not used, the embedded pillar type shown in FIG. 4 cannot deal with this, and the anchor bolt fixing method shown in FIG. It is possible to remove the support 11 by releasing the engagement of the nut 14, but the support 11 must be supported during the work, the removal work is complicated, and the treatment of the removed support 11 is troublesome. , For example, if the pillar is left on the roadside, the pillar gives the driver a feeling of pressure and impairs the scenery.
In the prop storage system shown in the figure, the prop 11 is tilted in the installation extension direction, so it cannot handle cases where there is no tilt space, and the tilted prop gives the driver a sense of pressure and the scenery. There was a problem of damage.
他方、従来より、車止め、フェンス、門扉等について

そのまま採用することはできない。On the other hand, conventionally, regarding car stops, fences, gates, etc., as shown in Japanese Utility Model Laid-Open No. 61-106520 and Japanese Utility Model Laid-Open No. 62-107100, there has been proposed a method of storing a support pillar in the ground. . However, in car stops, fences, gates, etc., not so much external force acts on the fence body and stanchions, whereas in the blow-off fence, wind pressure such as snowstorm acts on the fence body and stanchions, and there is concern that the stanchions may collapse. Therefore, it is not possible to directly adopt the above-mentioned small-scale structure method.
また、特開昭64-21105号公報に示されるように、支柱を
杭基礎内に出没自在とした吹払柵用支柱構造が提案され

解決すべき種々の技術的課題がある。Further, as disclosed in Japanese Patent Laid-Open No. 64-21105, a strut structure for blow-off fences has been proposed in which the strut is freely retractable in the pile foundation, but such a strut structure can be installed even in a relatively narrow space. However, how to attach the pillar to the pile foundation, how to handle the removed fence main body, etc.
There are various technical problems to be solved.
この考案は、かかる問題点に鑑み、小さなスペースで基
礎を設置でき、しかも撤去した支柱の処置が容易な柵用
支柱構造を提供することを課題とする。In view of such a problem, an object of the present invention is to provide a support structure for a fence in which a foundation can be installed in a small space and the removed support can be easily treated.
（課題を解決するための手段） そこで本考案に係る柵用支柱構造は、支柱設置箇所には

基部間に係止可能となしたことを特徴とする。(Means for Solving the Problem) Therefore, in the fence strut structure according to the present invention, a pile foundation having a hollow cross section is vertically driven into the strut installation position, and the fence main body is detachably supported in the pile foundation. While the pillars are provided so as to be retractable, at least a pair of L-shaped fixed bases are fixed to the upper end of the pile foundation so as to face each other in the direction in which the external force acts on the pillars with a space for allowing the pillars to pass therethrough. A plurality of parts are formed to have a height that is at least twice the width of the column outer shape, and the lower end of the column that is in a protruding state is fixed to the vertical portion of the fixed base so as to be detachably fixed at a predetermined interval in the height direction. And the upper end of the strut is fixed to the vertical portion of the fixed base by the fixing member in the stored state, and the fixed base is provided with a locking component to adjoin the removed fence main body. It is characterized in that it can be locked between fixed bases It

あるいはコンクリート杭を採用でき、又その断面形状は
丸あるいは角等、支柱断面に対応したものであればよ
い。また、この杭基礎の長さ及び径は外力条件により構
造設計をするのが望ましい。Here, the pile foundation may be a steel pipe pile or a concrete pile having a hollow cross section and capable of accommodating a strut, and the cross-sectional shape may be round, square, or the like corresponding to the strut cross section. Also, it is desirable to design the length and diameter of this pile foundation according to the external force conditions.
また、固定部材は支柱を杭基礎に固定できるものであれ
ばどのようなものであってもよく、例えばボルト・ナッ
トを使用できる。The fixing member may be any member as long as it can fix the column to the pile foundation, and for example, bolts and nuts can be used.
（作用及び考案の効果） 本考案においては、垂直部分が支柱外形幅寸法の２倍以
上の高さのＬ字状固定基部を支柱の外力作用方向に支柱
挿通可能な間隔をあけて固定し、その垂直部分に支柱の
下端部を高さ方向に所定の間隔をあけで係脱可能に固定
するようにしたことから、支柱を固定基部に強固に固定
でき、地吹雪等の風圧に対しても確実に支柱を保持でき
る。(Operation and effect of the invention) In the present invention, the L-shaped fixed base portion whose vertical portion is at least twice as large as the column outer width dimension is fixed with a space for allowing the column to be inserted in the direction of the external force acting on the column, Since the lower end of the support pillar is fixed to the vertical part so that it can be disengaged at a predetermined interval in the height direction, the support pillar can be firmly fixed to the fixed base, and even against wind pressure such as snowstorm. The pillar can be held securely.
その結果、基礎として杭基礎を用いることができ、基礎
設置スペースが極めて少なく、隣地境界に余裕がない場
合にも設置が可能である。As a result, a pile foundation can be used as the foundation, the space for installing the foundation is extremely small, and the foundation can be installed even if there is no margin at the boundary of the adjacent land.
また、支柱を撤去する場合には固定部材を外せば、支柱

支柱の収納スペースを別途設ける必要がない。また、柵
本体を固定基部間に保持するようにしたことから、柵本
体を他の保管場所に運搬する必要がなく、又柵本体を紛
失するおそれもない。In addition, when removing the pillar, if the fixing member is removed, the pillar is stored in the pile foundation by its own weight and can be held in the housed state by the fixing member, so not only the removal work of the pillar is very easy. Since there is no risk of the fixing member being lost, and because the columns are stored in the pile foundation, there is no need to separately provide a storage space for the removed columns. Further, since the fence main body is held between the fixed bases, it is not necessary to transport the fence main body to another storage place, and there is no fear of losing the fence main body.

余裕がない場合であっても支柱２の設置が非常に容易と
なる。As a result, the pile foundation 1 can be adopted as the foundation of the pillar 2, and the foundation installation space becomes extremely small. For example, comparing the basic areas of the main strut structure and the conventional strut structure under the same external force conditions, the concrete block of the conventional structure is about
It is 1.6 m 2 , whereas it is 0.126 m 2 (400Φ) in the steel pipe pile (or concrete pile) of this structure, which shows that the installation space is very small. Therefore, even if there is no room in the adjacent land, the support 2 can be installed very easily.
また、ボルト・ナット６を外すのみで支柱２が杭基礎１
内に収納され、不使用時の柵撤去作業が極めて簡単であ

外への突出物分も小さくできるので、支柱２がドライバ
ーに圧迫感を与えることもなく、又景観を損なうことも
ない。In addition, the pillar 2 becomes the pile foundation 1 only by removing the bolts and nuts 6.
Since it is housed inside, it is extremely easy to remove the fence when not in use, and there is no need to install the removed support post 2 on the roadside, and the amount of protrusion to the outside can be reduced, so the support post 2 presses the driver. It does not give a feeling and does not damage the landscape.
