【発明の属する技術分野】
本発明は、地籍調査を行うような場合に使用される土地や道路の位置に関する情報、または、その位置のケーブル、水道管、ガス管等の地下埋設物に関する情報のような、地理的情報を表示するための標示杭に関するものである。
【0002】
【従来の技術】
従来、地籍調査等を行う場合には、位置標示部材として、例えば、細長い棒状とされた杭本体の頭部に、地表に露出するキャップが取り付けられた測量杭が使用されている。このキャップの上面に、土地の境界表示や区画番号、基準点からの距離、地下埋設物の情報等の地理的情報に関連付けた識別番号や識別記号が付された表示プレートをピンで固定したものがある(例えば、実用新案文献1)。
【0003】
【実用新案文献1】
実用新案登録第2527607号公報(第2頁第3欄第21行目ないし同第4欄第34行目、第1図)
【0004】
ところで、この測量杭は、地盤に打ち込んだ後、前記表示プレートを取り付けるので、現場での杭の打ち込みとプレート取り付けの2つの作業を行う必要があり、現場作業の量が増す。
【0005】
そこで、本発明の目的は、現場での表示プレートの取付作業が不要な標示杭を提供することにある。
【0006】
【課題を解決するための手段】
上記目的を達成するために、本発明に係る標示杭は、杭本体の頭部にキャップが被せられ、地盤に埋設される標示杭であって、前記キャップの上面もしくは側面に、外面に地理的情報を付した表示部材がインサート成形によって固定されている。
【0007】
前記構成によれば、表示部材は製造過程において標示杭に取り付けられるため、杭の打ち込み現場で標示杭に表示プレートを取り付ける作業がなくなり、現場作業を少なくすることができる。
【0008】
また、本発明の好ましい実施形態では、表示部材は、前記地理的情報が表示されたプレート部と、前記杭本体内に埋入される抜け止め部とを有している。この構成によれば、長年の設置によりプレート部が風化した場合でも、抜け止め部により表示部材の脱落を防ぐことができる。
【0009】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図1に示す標示杭Aは、細長い、例えば断面十字形とされた杭本体1の先端側に先鋭部11を、他方側に四角柱形状とされた頭部10をそれぞれ形成して、この頭部10を覆う樹脂製のキャップ12を取り付けている。キャップ12の上面12aには表示部材20が固定されている。標示杭Aを構成する杭本体1およびキャップ12の横断面形状は、三角形、四角形以上の多角形、円形等、種々の形状とすることができる。
【0010】
杭本体1は、樹脂製、木製、またはコンクリート製であり、通常、樹脂製のものが好ましく用いられる。この樹脂製の杭本体1に使用される材料としては、例えば、ポリエチレン、ポリプロピレン、ポリエステル、スチロール、ポリアミド、ポリスルホン等の熱可塑性プラスチックで形成された樹脂製品の廃物である、リサイクル樹脂が用いられる。
【0011】
杭本体1の頭部10を覆うキャップ12には、ポリエチレン、ポリプロピレン、フッ素、ポリカーボネート、ポリスルホン、ポリエステル等の熱可塑性樹脂や、フェノール、ポリイミド等の熱硬化性樹脂が用いられる。
【0012】
キャップ12の上面12aに固定されている表示部材20は、例えば、アルミニウム製またはステンレス製であり、図2に示すように、一部が標示杭Aの上面12aに露出するプレート部21と、杭本体1内に埋入される抜け止め部22とを有している。プレート部21は、円形、多角形などの任意の形状のものが使用できるが、通常、図2に示すように円形状が好ましく用いられる。また、プレート部21の外面には、標示杭Aの識別符号、土地の境界表示や区画番号、基準点からの距離、地下埋設物の情報等の地理的情報が印刷または刻設される。本実施形態の場合、「国土調査」のような文字と、「8129」のような識別符号が刻印されている。この識別符号は、データセンタから地理的情報を得るために利用される。さらに、プレート部21の中央には、円盤形のボス24が設けられ、このボス24に、測量地点を示す十字溝23が形成されており、十字の中心部分には、測量用のポールが挿入される挿入孔25が形成されている。
【0013】
前記抜け止め部22は、先端部が曲げられて鉤状になっており、図3に示すように、杭本体1内に埋入され、標示杭Aに表示部材20を固定している。この抜け止め部22により、プレート部21が風化しても、表示部材20の脱落が防止される。抜け止め部22の先端部は曲がっていなくても、ある程度の抜け止めの効果は得られる。
【0014】
このプレート部21および抜け止め部22を有する表示部材20は、線材からヘッダーを用いて一体成形される。
【0015】
次に、本発明の標示杭Aの成形方法について簡単に説明する。
前記表示部材20は、予めキャップ12にインサート成形する。キャップ12は、図3のように、キャップ12の上面12aからプレート部21の一部が露出し、キャップ12の内側には抜け止め部22が突出した状態になる。
この表示部材20がインサート成形されたキャップ12を標示杭A成形用の型に嵌め込み、リサイクル樹脂を用いて型成形することにより、表示部材20を備えたキャップ12付きの標示杭Aが成形される。
【0016】
本実施形態では、表示部材20をキャップ12の上面12aにインサート成形で取り付けたが、キャップ12の側面12bにインサート成形で取り付けてもよい。
【0017】
また、本発明の表示部材20への地理的情報の印刷または刻印は、取り付け前の、表示部材20単独の状態で行ってもよいし、インサート成形し、標示杭Aに取り付けた後の状態で行ってもよい。
【0018】
【発明の効果】
以上のように、本発明に係る標示杭によれば、表示部材が製造過程において標示杭に取り付けられるため、杭の打ち込み現場で標示杭に表示プレートを取付け作業がなくなり、現場作業を少なくすることができる。

Japanese Utility Model Registration No. 2527607 (Page 2, column 3, line 21 to column 4, line 34, FIG. 1)
[0004]
By the way, since the surveying pile is driven into the ground and then the display plate is attached thereto, it is necessary to perform two operations of driving the pile and mounting the plate at the site, which increases the amount of site work.
[0005]
Therefore, an object of the present invention is to provide a sign pile that does not require a display plate mounting operation on site.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a marking pile according to the present invention is a marking pile in which a cap is put on a head of a pile main body and is buried in the ground. A display member with information is fixed by insert molding.
[0007]
According to the above configuration, since the display member is attached to the sign pile in the manufacturing process, the work of attaching the display plate to the sign pile at the pile driving site is eliminated, and the on-site work can be reduced.
[0008]
In a preferred embodiment of the present invention, the display member has a plate portion on which the geographic information is displayed, and a retaining portion embedded in the pile main body. According to this configuration, even when the plate portion is weathered due to long-term installation, the display member can be prevented from falling off by the retaining portion.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A marking pile A shown in FIG. 1 is formed by forming a sharpened portion 11 on the tip side of a slender, for example, cross-shaped pile main body 1, and a square pillar-shaped head 10 on the other side. A resin cap 12 that covers the part 10 is attached. The display member 20 is fixed to the upper surface 12a of the cap 12. The cross-sectional shapes of the pile main body 1 and the cap 12 constituting the marking pile A can be various shapes such as a triangle, a polygon having four or more squares, and a circle.
[0010]
The pile body 1 is made of resin, wood, or concrete, and usually, resin is preferably used. As a material used for the resin-made pile body 1, for example, a recycled resin, which is a waste product of a resin product formed of a thermoplastic plastic such as polyethylene, polypropylene, polyester, styrene, polyamide, or polysulfone, is used.
[0011]
A thermoplastic resin such as polyethylene, polypropylene, fluorine, polycarbonate, polysulfone, or polyester, or a thermosetting resin such as phenol or polyimide is used for the cap 12 that covers the head 10 of the pile body 1.
[0012]
The display member 20 fixed to the upper surface 12a of the cap 12 is made of, for example, aluminum or stainless steel, and as shown in FIG. And a retaining portion 22 embedded in the main body 1. The plate portion 21 may have an arbitrary shape such as a circle or a polygon, but usually, a circular shape is preferably used as shown in FIG. Further, on the outer surface of the plate portion 21, geographical information such as an identification code of the marking pile A, a boundary display of the land, a section number, a distance from a reference point, and information on an underground buried object is printed or engraved. In the case of the present embodiment, characters such as “land survey” and an identification code such as “8129” are engraved. This identification code is used to obtain geographic information from the data center. Further, a disc-shaped boss 24 is provided at the center of the plate portion 21, and a cruciform groove 23 indicating a surveying point is formed in the boss 24, and a survey pole is inserted into the center of the cross. An insertion hole 25 is formed.
[0013]
The tip of the retaining portion 22 is bent into a hook shape, is embedded in the pile main body 1, and fixes the display member 20 to the marking pile A, as shown in FIG. 3. The retaining member 22 prevents the display member 20 from falling off even if the plate portion 21 is weathered. Even if the tip of the retaining portion 22 is not bent, a certain degree of retaining effect can be obtained.
[0014]
The display member 20 having the plate portion 21 and the retaining portion 22 is integrally formed from a wire using a header.
[0015]
Next, a method for forming the marking pile A of the present invention will be briefly described.
The display member 20 is insert-molded on the cap 12 in advance. As shown in FIG. 3, the cap 12 has a state in which a part of the plate portion 21 is exposed from the upper surface 12 a of the cap 12, and the retaining portion 22 protrudes inside the cap 12.
The indicator pile A with the cap 12 having the indicator member 20 is formed by fitting the cap 12 in which the display member 20 is insert-molded into a mold for molding the indicator pile A, and molding the same using recycled resin. .
[0016]
In the present embodiment, the display member 20 is attached to the upper surface 12a of the cap 12 by insert molding, but may be attached to the side surface 12b of the cap 12 by insert molding.
[0017]
In addition, the printing or engraving of the geographical information on the display member 20 of the present invention may be performed in a state of the display member 20 alone before the mounting, or may be performed by insert molding and after being mounted on the marking pile A. May go.
[0018]
【The invention's effect】
