Description

本考案は、河川の水位を示す量水標に関する。 The present invention relates to a quantitative water mark indicating the water level of a river.

河川やダムの水位を観測する目的で、護壁に量水標を設置することが広く行われている。量水標は、幅１３０ミリないし１５０ミリメートル、長さ１０００ミリメートル、厚さ１ないし２ミリメートル程度のステンレスまたはアルミ板であり、その表面に数字や目盛を印刷したものである。 For the purpose of observing the water level of rivers and dams, it is widely practiced to install water marks on the walls. The quantity water mark is a stainless steel or aluminum plate having a width of 130 mm to 150 mm, a length of 1000 mm, and a thickness of 1 to 2 mm, and numbers and scales are printed on the surface thereof.

このように従来の量水標は一般に薄板状であるため、凹凸のある護壁に量水標を設置すると、表面に曲げ変形が発生しやすいという問題がある。そこで、従来、凹凸のある護壁に量水標を設置する際には、裏側に塩ビ板を裏打ちするように設置している。 As described above, since the conventional water quantity indicator is generally in the form of a thin plate, there is a problem that bending deformation is likely to occur on the surface when the water quantity indicator is installed on an uneven protection wall. Therefore, conventionally, when installing a water mark on an uneven barrier, it has been installed so that a PVC board is lined on the back side.

なお、固定面に対して上下方向に並べた状態で固定される複数枚の目盛板で構成した量水標であって、それぞれの目盛板の中央部を、その側縁部より手前側に凸とした量水標が特許文献１に開示されている。 In addition, it is a quantitative water mark composed of a plurality of scale plates fixed in a state of being arranged in the vertical direction with respect to the fixed surface, and the center portion of each scale plate protrudes to the near side from its side edge portion. A quantitative water mark is disclosed in Patent Document 1.

上述のように、上記従来の量水標では、裏側に塩ビ板等を配しているため、設置時には塩ビ板の加工などの作業も必要となり、設置に手間がかかっていた。また、塩ビ板の厚さだけ護壁から離れてしまうため、川底やダムの底面を水位「０」として設置してしまうと、その水位の読み取り誤差が生じる場合がある。例えば塩ビ板の厚さをｔ、護壁の角度が垂直方向からθである場合、誤差はｔ×ｓｉｎ（θ）となるので、仮にθが３０度の場合、厚さｔ＝２０ミリメートルの塩ビ板を使用した場合、約１０ミリメートルの読み取り誤差を生じる。ダム等の管理では、この水位の差は無視できる値ではないため、設置時にこの誤差を考慮しなければならず、設置工事にさらに手間がかかるという問題点があった。 As described above, in the conventional water quantity indicator, since a vinyl chloride plate or the like is arranged on the back side, work such as processing of the vinyl chloride plate is required at the time of installation, and it takes time to install. In addition, since it is separated from the barrier by the thickness of the PVC plate, if the bottom of the river or the dam is set at the water level “0”, an error in reading the water level may occur. For example, if the thickness of the PVC plate is t and the angle of the protective wall is θ from the vertical direction, the error is t × sin (θ). Therefore, if θ is 30 degrees, the PVC plate having a thickness t = 20 mm Results in a reading error of about 10 millimeters. In the management of dams and the like, this difference in water level is not negligible, so this error must be taken into account at the time of installation, and there is a problem that it takes more time for installation work.

本考案は上記実情に鑑みて為されたもので、裏打ち作業等の必要なく、設置工事を簡便にできる量水標を提供することを、その目的の一つとする。 The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a quantity water mark that can simplify installation work without the need for backing work or the like.

上記従来例の問題点を解決する本考案の一態様は、表面側に水位標識が表された平板細長状の量水標であって、幅方向の縁部を裏面側に折り返した折返部を設けたものである。 One aspect of the present invention that solves the problems of the conventional example described above is a flat and slender water mark with a water level indicator on the front surface side, and a folded portion having a widthwise edge folded back on the back surface side. It is provided.

また、前記折返部に重ならない中央範囲が、裏面側に凸となる台形状に加工され、前記折返部を含めた裏面側が実質的に平面に形成されてもよい。 Moreover, the center range which does not overlap the said folding | returning part may be processed into the trapezoid shape which becomes convex on the back surface side, and the back surface side including the said folding | turning part may be formed in a plane substantially.

本考案によると、折返部により変形が抑制されるため裏打ち作業等の必要がなく、設置工事を簡便にできる。 According to the present invention, since the deformation is suppressed by the folded portion, there is no need for a backing work or the like, and the installation work can be simplified.

本考案の実施の形態について図面を参照しながら説明する。なお、以下の説明及び図面において、各部のサイズや比率は例示されたものであり、実際には、適宜のサイズ、比率で設計され得る。 Embodiments of the present invention will be described with reference to the drawings. In the following description and drawings, the sizes and ratios of the respective parts are illustrated, and in actuality, they can be designed with appropriate sizes and ratios.

本考案の実施の形態に係る量水標１０は、図１に例示するように、平板細長状をなす本体部１１と、標識部１２とを含む。本体部１１は、その幅方向の縁部２１（水流が当たる方向）が長手方向に亘って、図２にその一例を例示するように、裏面側に、Ｐ曲げまたはヘミング曲げ加工などにより折り返されて折返部２２が形成される。 As shown in FIG. 1, the water quantity indicator 10 according to the embodiment of the present invention includes a main body portion 11 having an elongated plate shape and a marker portion 12. The main body 11 is folded back on the back side by P-bending or hemming bending or the like, as illustrated in FIG. Thus, the folded portion 22 is formed.

標識部１２は、耐水性を有するシート状の印刷物であり、水位を示す図形や文字等が印刷されてなる。この標識部１２は、本体部１１の表面側１１ａに貼り付けられる。図１は、本実施の形態の量水標１０の一部を表す斜視図であり、図２はその断面図を表す。 The indicator 12 is a sheet-like printed material having water resistance, and is printed with figures, characters, and the like indicating the water level. The label portion 12 is affixed to the surface side 11 a of the main body portion 11. FIG. 1 is a perspective view showing a part of a quantity water mark 10 of the present embodiment, and FIG. 2 is a sectional view thereof.

図２の例では、量水標１０の本体部１１の幅方向縁部２１が裏面側１１ｂ（標識部１２が貼り付けられた面とは反対側の面に向かって）折り返され、当該折返部２２が本体部１１の表面に積層された（重なり合った）状態とされている。また、その表面側１１ａは、平面となっている。 In the example of FIG. 2, the width direction edge portion 21 of the main body portion 11 of the water mark 10 is folded back (toward the surface opposite to the surface on which the marker portion 12 is attached), and the folded portion. 22 is laminated (overlapped) on the surface of the main body 11. Moreover, the surface side 11a is a plane.

この例の量水標１０では、図３に例示するように、本体部１１を折り返して積層した位置Ｐに開口を形成し、この開口を通じてアンカーボルトＡを打ち込んで護岸Ｇに固定する。本実施の形態のこの例によると、幅方向（流水が当たる側）の両端部所定範囲を折り返して積層し、多層構造を形成したことで容易な加工により、十分な強度を確保し、量水標１０の変形が抑制されるため裏打ち作業等の必要がなく、設置工事を簡便にできる。 In the quantity water mark 10 of this example, as illustrated in FIG. 3, an opening is formed at a position P where the main body portion 11 is folded and stacked, and the anchor bolt A is driven through the opening to be fixed to the revetment G. According to this example of the present embodiment, the predetermined range at both ends in the width direction (the side where the running water hits) is folded and laminated, and a multilayer structure is formed to ensure sufficient strength, Since deformation of the mark 10 is suppressed, there is no need for a backing operation or the like, and installation work can be simplified.

また、本実施の形態の別の例では、図４に例示するように、曲げ加工の際に生じる曲げコブ２２Ｒを、裏面側から表面側に押し出す加工を行ってもよい。これにより量水標１０の本体部１１の幅方向両端部近傍に、長手方向に延び、表面方向に凸となる凸部２３が形成された状態となる。またこの例では、両端の凸部２３の間に標識部１２を貼付する。 In another example of the present embodiment, as illustrated in FIG. 4, the bending bump 22 </ b> R generated during bending may be processed to be pushed from the back side to the front side. Thereby, it will be in the state by which the convex part 23 extended in a longitudinal direction and convex in the surface direction was formed in the width direction both ends vicinity of the main-body part 11 of the quantity water mark 10. FIG. Moreover, in this example, the label | marker part 12 is stuck between the convex parts 23 of both ends.

本実施の形態の一例では、この図４に例示したように、幅方向（流水が当たる側）の両端部に設けられた凸部２３の間に標識部１２が貼り付けられるので、標識部１２の側面に流水が当たり続けることによる標識部１２の剥離が生じにくい。 In the example of the present embodiment, as illustrated in FIG. 4, the marker portion 12 is attached between the convex portions 23 provided at both ends in the width direction (the side on which the running water hits). The marking part 12 is less likely to be peeled off due to the continuous running of water on the side surface of.

さらに本実施の形態のもう一つの例では、図５に例示するように、図２，図４に例示した状態からさらに、本体部１１の折返部２２が積層されない（折返部２２に重ならない）中央範囲が、裏面側に凸となる台形状に加工されて、折返部２２を含めた裏面側が実質的に平面に形成される。図５の例は、図４に例示した状態からさらに本体部１１の幅方向中央の所定範囲を表面から裏面側へ押圧して、台形状部分２４（表面側がやや凹となる部分）を形成する。 Furthermore, in another example of the present embodiment, as illustrated in FIG. 5, the folded portion 22 of the main body portion 11 is not further stacked (does not overlap the folded portion 22) from the state illustrated in FIGS. 2 and 4. The central range is processed into a trapezoidal shape that is convex on the back surface side, and the back surface side including the folded portion 22 is formed substantially in a flat surface. In the example of FIG. 5, a predetermined range in the center in the width direction of the main body 11 is further pressed from the front surface to the back surface side from the state illustrated in FIG. 4 to form a trapezoidal portion 24 (a portion where the front surface side is slightly concave). .

この図５の例では、両端の凸部２３の間（存在する場合）で、台形状部分２４の範囲に標識部１２を貼付する。この図５に示した例では、量水標１０の裏面側が護岸に当接した（あるいは断続的に接した）状態となるので、アンカーボルトを打ち込んだ状態で護岸から浮き上がった部分が少なくなり、流水があっても振動等もなく、また、標識部１２の側面に流水が直接当たることが避けられるので、標識部１２の剥離も生じにくい。 In the example of FIG. 5, the marker 12 is pasted in the range of the trapezoidal portion 24 between the convex portions 23 at both ends (if present). In the example shown in FIG. 5, since the back side of the water mark 10 is in contact with (or intermittently in contact with) the revetment, the portion that has lifted from the revetment with the anchor bolts driven in is reduced. Even if there is running water, there is no vibration or the like, and since it is avoided that the running water directly hits the side surface of the sign part 12, the sign part 12 is hardly peeled off.

本実施の形態の以上の各例では、流水が当たる幅方向の両端部所定範囲を折り返して積層し、多層構造を備えた量水標１０としたので、十分な強度を確保でき、また量水標１０の本体の変形が抑制されて、裏打ち作業等の必要がなくなり、設置工事を簡便にできる。 In each of the above examples of the present embodiment, the predetermined range in both ends in the width direction where the running water hits is folded and laminated, and the water quantity indicator 10 having a multilayer structure is obtained, so that sufficient strength can be secured, Since the deformation of the main body of the mark 10 is suppressed, there is no need for a backing work or the like, and the installation work can be simplified.
