Description

本発明は、主として道路脇に設置される道路標識、カーブミラー又は防護柵等の支柱の設置に際し、容易な施工作業で前記支柱の高さ位置を仮固定できるプレキャスト型のコンクリートブロック又は施工現場打設型のコンクリートブロック、及び、係止部材に関するものである。   The present invention mainly provides a precast type concrete block or a construction site caster capable of temporarily fixing the height position of the support column by an easy installation work when installing a support such as a road sign, a curved mirror, or a guard fence, which is installed on the side of the road. The present invention relates to a stationary concrete block and a locking member.

地面に対して、道路標識等の「支柱」を設置する技術に関して、出願人は特許文献１に記載の発明を提案している。この特許文献１に記載の発明は、ブロック本体の上面に支柱を挿入するための支柱固定用孔が形成され、其処へ支柱を挿入することによって、当該支柱を立設するものである。かかる発明によれば、短い工期で支柱を安定的に設置できる点で、極めて有効な技術であるといえる。   The applicant has proposed the invention described in Patent Document 1 regarding a technique for installing a “post” such as a road sign on the ground. In the invention described in Patent Document 1, a column fixing hole for inserting a column is formed on the upper surface of the block body, and the column is erected by inserting the column into the hole. According to this invention, it can be said that it is a very effective technique in that the column can be stably installed in a short construction period.

しかしながら、上記のような支柱は、地面からの突出寸法が常に一定であることが要求される。そのため、上記特許文献１に記載の発明により該支柱を支柱固定用孔内に固定する際は、複数の作業者による施工が必要であった。具体的には、複数の作業者のうち一方の作業者が支柱を把持して高さ位置を保持した状態で、他方の作業者が前記支柱と支柱固定用孔との隙間に木片等を打ち込んで、高さ方向への位置決め（仮止め）を行う必要がある。尚、一人の作業者による施工も不可能ではないが、非常に面倒な作業となる。具体的には、先ず当該支柱を支柱固定用孔内に挿入することによって必要な「底上げ寸法」を確認し、次に当該支柱を引き抜き支柱固定用孔内に砂利等を投入して底上した後、再度支柱を挿入する作業が必要となるのである。   However, the above-mentioned support columns are required to have a constant projecting dimension from the ground. Therefore, when the column is fixed in the column fixing hole according to the invention described in Patent Document 1, construction by a plurality of workers is required. Specifically, with one of the workers holding the column and holding the height position, the other operator drives a piece of wood or the like into the gap between the column and the column fixing hole. Therefore, it is necessary to perform positioning (temporary fixing) in the height direction. Although construction by a single operator is not impossible, it is a very troublesome work. Specifically, the necessary “bottom raising dimension” is confirmed by first inserting the column into the column fixing hole, and then the column is pulled out and the gravel or the like is put into the column fixing hole to raise the bottom. Later, it is necessary to insert the support again.

なお、上記支柱の高さ方向への位置決め（仮止め）の問題は、特許文献２の図３に示す形態の如く、支柱の側方から棒状部材を貫通させ、当該支柱をブロックの支柱固定用孔に挿入して、前記棒状部材をブロック上面に係合させることによって解決可能であるとも考え得る。しかしながら、本願発明における「支柱」とは、主として道路脇に設置される道路標識、カーブミラー又は防護柵等の支柱であり、長期間にわたり確実に使用できなければならない。かかる支柱は強度確保の必要性から鋼鈑によって構成されるものである。そのため、上記特許文献２に記載の発明の如く支柱自体に貫通孔を形成した場合には、当該支柱自体の強度が低下するのは勿論のこと、当該貫通孔から雨水等が支柱内側へと滲入して該支柱を腐食させ、該支柱の耐久性が低下するという問題が生じる。   Note that the problem of positioning (temporary fixing) in the height direction of the column is that a rod-shaped member is penetrated from the side of the column and the column is fixed to the column column as shown in FIG. It can be considered that the problem can be solved by inserting the rod-shaped member into the upper surface of the block by inserting it into the hole. However, the “post” in the present invention is a post such as a road sign, a curve mirror, a guard fence or the like installed mainly on the side of the road, and must be used reliably over a long period of time. Such a support is composed of a steel plate in order to ensure strength. For this reason, when a through hole is formed in the column itself as in the invention described in Patent Document 2, not only the strength of the column itself is lowered, but also rainwater or the like infiltrates from the through hole to the inside of the column. As a result, the column is corroded, and the durability of the column decreases.

一方、上記の如き支柱は、地面に対して垂直に立設する必要がある。この点、上記特許文献１に記載の発明により該支柱を支柱固定用孔内に固定する際にあっては、複数の作業者のうち一方の作業者が支柱を把持した状態で、他方の作業者が少なくとも２方向から角度を計測して垂直を割り出し、しかる後、速やかに支柱と支柱固定用孔との隙間に砂やモルタルを流し込んで、当該支柱の垂直状態を維持する必要がある。なお、支柱を垂直に立設しなければならないのは平坦な場所だけではなく、勾配の急な坂道であっても事情は同じである。このような施工環境にあっては、高度に熟練した技術が要求されるため、施工コストにも影響するという問題が生じる。
特願２００５−１１８５０１号 特許第３４９７１５５号公報（図３） On the other hand, the above-mentioned support columns need to be erected vertically with respect to the ground. In this regard, when the support column is fixed in the support column fixing hole according to the invention described in Patent Document 1, one of a plurality of workers is holding the support column and the other operation is performed. It is necessary for the person to measure the angle from at least two directions to determine the vertical, and then immediately pour sand or mortar into the gap between the column and the column fixing hole to maintain the column in a vertical state. In addition, the situation is the same not only on a flat place but also on a steep slope where it is necessary to set up the pillar vertically. In such a construction environment, a highly skilled technique is required, which causes a problem of affecting the construction cost.
Japanese Patent Application No. 2005-118501 Japanese Patent No. 3497155 (FIG. 3)

そこで本発明は、以上の問題点に鑑みて案出されたものであり、道路標識、カーブミラー又は防護柵等の支柱の設置に際しては施工時の省力化を図ることができ、工期短縮及び施工コストの低廉化を実現する支柱立設用コンクリートブロック及び係止部材を安価に提供することを目的とするものである。   Therefore, the present invention has been devised in view of the above problems, and can save labor during construction when installing pillars such as road signs, curve mirrors or protective fences, shortening the construction period and construction. An object of the present invention is to provide a concrete block for standing uprights and a locking member that can realize cost reduction at low cost.

以上のような課題を解決するために、本願発明が採った手段は以下の通りである。   In order to solve the problems as described above, the means taken by the present invention are as follows.

まず請求項１に係る発明の支柱立設用コンクリートブロックは、道路標識、カーブミラー、防護柵等の支柱を設置するためのコンクリートブロックであって、当該ブロックの上面に連通する、前記支柱が挿入される支柱固定用孔が穿設されると共に、当該ブロックの上面に、前記支柱の設置高さ位置を設定するための当該支柱から横方向へと突出する係止部材を載架するための１又は２以上の被係止凹部を、設けたことを特徴とするものである。   First, the concrete block for standing pillar of the invention according to claim 1 is a concrete block for installing a pillar such as a road sign, a curved mirror, a guard fence, etc., and the pillar that is communicated with the upper surface of the block is inserted. 1 for mounting a locking member that protrudes laterally from the column for setting the installation height position of the column on the upper surface of the block. Alternatively, two or more locked recesses are provided.

次に請求項２に係る発明は、請求項１に記載した支柱立設用コンクリートブロックにおいて、当該ブロックの上面における支柱固定用孔周縁部の２以上の箇所に、支柱から両横へ突出する係止部材が載架されて当該支柱を略垂直方向に自立させるための被係止凹部を、設けたことを特徴とするものである。   Next, the invention according to claim 2 is a concrete block for standing pillars according to claim 1, wherein the support blocks project from the pillars to both sides at two or more locations on the peripheral edge of the pillar fixing hole on the upper surface of the block. It is characterized in that a locked recess is provided on which the stop member is placed to make the support column self-standing in a substantially vertical direction.

また請求項３に係る発明は、支柱立設用コンクリートブロックの支柱固定用孔内に挿入される支柱の外周面における任意の高さ位置に嵌装固定可能な、前記支柱の横方向へ突出する１又は２以上のアームを有する係止部材であって、当該係止部材を装着した支柱を支柱固定用孔内に挿入した際、前記１又は２以上のアームがコンクリートブロック上面に載架されることを特徴とするものである。   Moreover, the invention which concerns on Claim 3 protrudes in the horizontal direction of the said support | pillar which can be mounted and fixed to the arbitrary height positions in the outer peripheral surface of the support | pillar inserted in the support | pillar fixing hole of the concrete block for support | pillar standing. A locking member having one or more arms, wherein the one or more arms are mounted on the upper surface of the concrete block when a support column equipped with the locking member is inserted into the column fixing hole. It is characterized by this.

さらに請求項４に係る発明は、請求項３に記載した係止部材において、アームは両横方向へ略同軸線上に２本突出してなり、ブロックの上面の支柱固定用孔周縁部の２箇所に形成した被係止凹部に各々載架されることを特徴とするものである。   Furthermore, the invention according to claim 4 is the locking member according to claim 3, wherein the arms protrude in two lateral directions substantially on the same coaxial line, and are provided at two positions on the periphery of the column fixing hole on the upper surface of the block. It is each mounted in the formed to-be-latched recessed part, It is characterized by the above-mentioned.

そして請求項５に係る発明は、請求項３又は４に記載した係止部材において、アームが支柱の重心位置よりも高くなるように嵌装されて、被係止凹部に係止されることを特徴とするものである。   According to a fifth aspect of the present invention, in the locking member according to the third or fourth aspect, the arm is fitted so as to be higher than the position of the center of gravity of the support and is locked in the locked recess. It is a feature.

上記手段を採ったことにより得られる効果は以下の通りである。   The effects obtained by adopting the above means are as follows.

まず請求項１に係る発明のブロックは、その上面に連通する支柱固定用孔及び被係止凹部が設けられている。そして、当該被係止凹部には支柱から横方向に突出した係止部材が載架されることとなる。そのため、当該支柱固定用孔内に支柱を挿入した際には、当該支柱から突出した係止部材が前記被係止凹部に載架されて、当該ブロックに対する支柱の設置高さ位置の設定を容易に行うことが可能となる。また、前記支柱から突出した係止部材は、ブロックの上面の被係止凹部に受容されてブロック上面における水平方向へのズレを確実に防止できるため、前記支柱の設置高さ位置の設定と同時に、水平方向への位置決め（仮止め）も可能となる。   The block according to the first aspect of the present invention is provided with a column fixing hole and a locked recess that communicate with the upper surface of the block. And the latching member which protruded in the horizontal direction from the support | pillar will be mounted in the said to-be-latched recessed part. Therefore, when the column is inserted into the column fixing hole, the locking member protruding from the column is placed on the locked recess, so that the setting height position of the column with respect to the block can be easily set. Can be performed. In addition, since the locking member protruding from the support can be received in the locked recess on the upper surface of the block and can surely prevent the horizontal displacement on the upper surface of the block, simultaneously with the setting of the installation height position of the support Further, positioning in the horizontal direction (temporary fixing) is also possible.

次に請求項２に係る発明の支柱立設用コンクリートブロックは、当該ブロック上面の２以上の箇所に被係止凹部を有するものである。当該被係止凹部には支柱から横方向に突出した係止部材が載架されることとなる。従って、支柱固定用孔内に当該支柱を挿入して該支柱両側の係止部材をブロック上面の各被係止凹部で載架させた際には、支柱は当該係止部材を支点として吊られた状態となる。ここで、被係止凹部を２箇所とし、尚かつ支柱の重心が前記係止部材よりも下側となるよう設定した場合、当該支柱は略垂直方向に自立した状態となる。更に、被係止凹部を３箇所或いは４箇所とした場合には、支柱の重心位置に関わらず当該支柱は略垂直方向に自立した状態となる。即ち本請求項に係る発明によれば、当該ブロックに対する支柱の設置高さ位置の設定及び水平方向への位置決め（仮止め）の実現に加え、該ブロックに対し支柱を略垂直状態に自立させることを可能とするのである。   Next, the concrete block for standing upright of the invention which concerns on Claim 2 has a to-be-latched recessed part in two or more places of the said block upper surface. A locking member that protrudes laterally from the column is placed on the locked recess. Therefore, when the column is inserted into the column fixing hole and the locking members on both sides of the column are mounted on the locked recesses on the upper surface of the block, the column is suspended with the locking member as a fulcrum. It becomes a state. Here, when the number of the recessed portions to be locked is two and the center of gravity of the support column is set to be lower than the locking member, the support column is in a self-standing state in a substantially vertical direction. Further, when the number of the recessed portions to be locked is three or four, the column is in a state of being self-supporting in a substantially vertical direction regardless of the position of the center of gravity of the column. That is, according to the present invention, in addition to setting the installation height position of the column with respect to the block and realizing the horizontal positioning (temporary fixing), the column can be made to stand in a substantially vertical state with respect to the block. Is possible.

また請求項３に係る発明の係止部材は、支柱に取り付けられて使用するものである。当該係止部材を装着した支柱を、支柱立設用コンクリートブロックの支柱固定用孔内に挿入した際には、該係止部材におけるアームはコンクリートブロック上面に載架されるため、支柱立設用コンクリートブロックに対する支柱の設置高さ位置を設定を容易に行うことが可能となる。また、施工現場での支柱に対する孔空け加工を要せず、どのような支柱に対しても自在に且つ瞬時に支柱高さの設定を行うことができる。さらに、支柱に対する孔空け加工を要しないことから、当該支柱の腐食も回避できる。   Further, the locking member of the invention according to claim 3 is used by being attached to the support column. When the column with the locking member is inserted into the column fixing hole of the column for standing column, the arm of the locking member is mounted on the top surface of the concrete block. It is possible to easily set the installation height position of the column with respect to the concrete block. In addition, it is possible to freely and instantaneously set the column height for any column without the need for drilling the column at the construction site. Furthermore, since no drilling is required for the column, corrosion of the column can be avoided.

さらに請求項４に係る発明によれば、係止部材の２本のアームがコンクリートブロック上面の被係止凹部によってそれぞれ受容されて載架されるため、支柱立設用コンクリートブロックに対する支柱の設置高さ位置の設定及び水平方向への位置決め（仮止め）が可能となる。また本請求項に係る発明によれば、当該係止部材を装着した支柱は、両横方向へ略同軸線上に突出した２本のアームによってコンクリートブロック上面の被係止凹部上に軸支された状態となる。そのため当該支柱は、アームを支点として前後方向にのみ揺動（回動）可能な状態となる。即ち、当該支柱が揺動する方向を絞り込むことができるため、一方向からの角度計測により容易に垂直を割り出すことができ、工期の短縮化を図ることができる。   Further, according to the invention of claim 4, since the two arms of the locking member are respectively received and mounted by the locked recesses on the upper surface of the concrete block, the installation height of the column with respect to the concrete block for column standing is set. Position setting and horizontal positioning (temporary fixing) are possible. Further, according to the invention of this claim, the support column to which the locking member is mounted is pivotally supported on the locked recess on the upper surface of the concrete block by the two arms protruding substantially coaxially in both lateral directions. It becomes a state. Therefore, the support column can swing (turn) only in the front-rear direction with the arm as a fulcrum. That is, since the direction in which the column swings can be narrowed, the vertical can be easily determined by measuring the angle from one direction, and the construction period can be shortened.

そして、請求項５に係る発明によれば、当該係止部材のアームを支柱の重心位置よりも高い位置に装着し、該支柱をブロックにおける支柱固定用孔内に挿入した際、前記係止部材における２本のアームがブロック上面の各被係止凹部で載架されるため、当該アームを支点として支柱が吊られた状態となる。このとき、支柱の重心は前記係止部材よりも下側にあるため、当該支柱は略垂直方向に自立した状態となる。従って本請求項に係る発明によれば、当該係止部材を装着した支柱のブロックに対する設置高さ位置の設定及び水平方向への位置決め（仮止め）の実現に加え、該ブロックに対し支柱を略垂直状態に自立させることが可能となるのである。   According to the fifth aspect of the present invention, when the arm of the locking member is mounted at a position higher than the position of the center of gravity of the column and the column is inserted into the column fixing hole in the block, the locking member Since the two arms are mounted on the respective locked recesses on the upper surface of the block, the support column is suspended from the arm as a fulcrum. At this time, since the center of gravity of the support column is located below the locking member, the support column is in a self-standing state in a substantially vertical direction. Therefore, according to the invention of this claim, in addition to the setting of the installation height position and the horizontal positioning (temporary fixing) of the support column to which the locking member is mounted, the support column is substantially omitted from the block. This makes it possible to stand in a vertical state.

本発明の「支柱立設用コンクリートブロック」及び「係止部材」を実施するための最良の形態について説明する。   The best mode for carrying out the “concrete block-standing concrete block” and the “locking member” of the present invention will be described.

最初に、本発明に係る支柱立設用コンクリートブロックは、道路標識、カーブミラー、防護柵等の支柱を設置するためのコンクリートブロックである。当該ブロックの本体の上面には、支柱が挿入される支柱固定用孔が形成され、当該ブロックの上面の１又は２以上の箇所には被係止凹部が形成されている。   First, the concrete block for standing pillars according to the present invention is a concrete block for installing pillars such as road signs, curve mirrors, protective fences and the like. A column fixing hole into which a column is inserted is formed on the upper surface of the main body of the block, and a locked recess is formed at one or more locations on the upper surface of the block.

まず支柱固定用孔は、道路標識、カーブミラー、防護柵等の支柱を挿入可能であればどのような形状であってもよいが、一般的には、当該支柱の外径寸法よりも若干大きい直径寸法の丸孔として構成される。かかる形態で構成した場合には、支柱をスムースに挿入でき、尚かつ、挿入後にあっては当該支柱の傾動を最小限に抑えることができるため好適である。尚、支柱の「垂直方向への自立」（後述）を行う場合には、上記形態よりも更に大きな直径寸法の丸孔として構成としたり、或いは、長孔（楕円形）として構成し、当該支柱の揺動空間を確保するようにしても良い。尚、当該支柱の角度が定まった後には、上記揺動空間（隙間）内に砂やモルタルを流し込み、ブロックに対する支柱の固定を行うこととなる。   First, the pillar fixing hole may have any shape as long as a pillar such as a road sign, a curve mirror, a guard fence, etc. can be inserted, but is generally slightly larger than the outer diameter of the pillar. Configured as a round hole with a diameter dimension. In the case of such a configuration, it is preferable that the support column can be smoothly inserted and that the tilting of the support column can be minimized after the insertion. In addition, when performing "independence to the vertical direction" (after-mentioned) of a support | pillar, it is comprised as a round hole of a larger diameter dimension than the said form, or it comprises as a long hole (oval shape), and the said support | pillar The rocking space may be secured. In addition, after the angle of the said support | pillar is settled, sand and mortar will be poured in into the said rocking | swiveling space (gap), and the support | pillar with respect to a block will be fixed.

次に被係止凹部は、支柱から横方向へと突出する係止部材（アーム）が載架されて当該支柱の高さ方向に対する位置決めを行うものである。かかる機能を発揮できれば如何なる形態のものであってもよいが、支柱自体（又は後述の係止部材）から横方向へと突出するアームを受容可能な形状・構造のものとし、当該アームが突出する位置・角度及び数量と対応させて形成される。一般的には、支柱のアームを水平に突設し、凹部も水平に構成する。かかる構成を採用することにより、アームの確実な受容が可能となり、ブロック上面における支柱の水平方向へのズレを防止でき、水平方向への位置決め（仮止め）も可能となる。また例えば、当該被係止凹部を、当該ブロックの上面における支柱固定用孔周縁部の２箇所（当該支柱固定用孔を挟んで同一軸線上対向して、且つ、その底面を水平）に設けた場合には、支柱から両横へと水平に突出する係止部材を載架させた際、当該支柱を揺動させるための軸支点として機能することになる。さらに当該被係止凹部が支柱の重心よりも高い位置に設けられた係止部材（アーム）を受容した場合には、当該被係止凹部から垂直方向へと自立する支柱を支持することとなる。尚、当該被係止凹部を、当該ブロックの上面における支柱固定用孔周縁部の３箇所又は4箇所（図１３参照）に設けた場合には、支柱から３方向又は４方向へ水平に突出する係止部材を載架させた際、当該被係止凹部から垂直方向へと自立する支柱を支持することとなる。当該被係止凹部を形成する場合には、図１０に示すように、キューブ状の部材が固定された筒状型枠を基礎型枠内に配置してコンクリートを打設・硬化させる場合の他、既に硬化したコンクリートブロック上面における支柱固定用孔の周縁部を切削工具で切削することにより形成してもよい。   Next, the locked concave portion is a member on which a locking member (arm) protruding in the lateral direction from the support is placed to position the support in the height direction. Any form may be used as long as such a function can be exhibited, but the arm projecting in the lateral direction from the column itself (or a locking member described later) has a shape and structure that can be received, and the arm projects. It is formed corresponding to the position, angle and quantity. In general, the arm of the column is projected horizontally and the recess is also constructed horizontally. By adopting such a configuration, it is possible to reliably receive the arm, to prevent the horizontal displacement of the support column on the upper surface of the block, and to perform the horizontal positioning (temporary fixing). In addition, for example, the locked recesses are provided at two positions of the peripheral edge of the support fixing hole on the upper surface of the block (opposite on the same axis across the support fixing hole and the bottom is horizontal). In this case, when a locking member that protrudes horizontally from the support is mounted, it functions as a pivot for pivoting the support. Further, when the locked recess receives a locking member (arm) provided at a position higher than the center of gravity of the support column, the support column that supports the support column in a vertical direction from the locked recess is supported. . In addition, when the said locked recessed part is provided in three places or four places (refer FIG. 13) of the support | pillar fixing hole peripheral part in the upper surface of the said block, it protrudes horizontally in three directions or four directions from a support | pillar. When the locking member is mounted, the support column that is self-supporting in the vertical direction from the locked recess is supported. In the case where the locked recess is formed, as shown in FIG. 10, other than the case where the cylindrical formwork to which the cube-like member is fixed is placed in the basic formwork and the concrete is placed and hardened. The peripheral edge of the column fixing hole on the upper surface of the already hardened concrete block may be formed by cutting with a cutting tool.

なお、ブロック本体に関してはどのような形状でもよく、最もシンプルな形状であれば、コンクリートを用いて立方体又は略直方体に形成し、上面から下面に向かって穿ってある支柱固定用孔を形成すれば足りる。この場合、施工現場で型枠を用いてコンクリート打設する場合と、施工現場にプレキャスト製品を運び込む場合とを問わない。ブロック本体の大きさについては限定するものではなく、また縦、横及び高さの比率についても限定するものではない。なお、支柱固定用孔の長さは限定するものではなく、上面から底面まで貫通して設けても、貫通させなくても構わない。さらに、設ける支柱固定用孔の数についても限定するものではなく、複数設けても構わない。複数設ければ一つの支柱立設用コンクリートブロックに複数の標識やカーブミラーなどを設置することができる。また、図１６に示す形態の如く、隣接して２つの支柱固定用孔を設ければ、隣り合う防護柵の支柱を立設して防護柵を連続して設置できるようになる。   The block body may have any shape, and if it is the simplest shape, it is formed into a cube or a substantially rectangular parallelepiped using concrete, and a column fixing hole drilled from the upper surface to the lower surface is formed. It ’s enough. In this case, it does not matter whether the concrete is cast using the formwork at the construction site or when the precast product is brought into the construction site. The size of the block main body is not limited, and the ratio of the vertical, horizontal, and height is not limited. The length of the column fixing hole is not limited, and may be provided so as to penetrate from the top surface to the bottom surface or not. Further, the number of support fixing holes to be provided is not limited, and a plurality of support fixing holes may be provided. If a plurality of signs are provided, a plurality of signs, curve mirrors, and the like can be installed on a concrete block for standing columns. Further, as shown in FIG. 16, if two support pillar fixing holes are provided adjacent to each other, the support fences can be continuously installed by standing the support pillars of adjacent protection fences.

ブロックの上面としては水平面に設けてもよいが、支柱固定用孔の近傍を最も高くし、その周囲を低く形成した傾斜面に設けるとよい。このような傾斜面とすれば、雨が降った場合においても、支柱やブロックの上面に降った雨水を周囲に流すことができ、錆等による腐食から支柱を守ることができる。この場合、凹部はその底部が略水平となるよう形成されるのが望ましいが、多少の傾きや高さの相違があっても、凹部に調整片を敷くなどすれば、簡単に水平化を図ることができる。   The upper surface of the block may be provided on a horizontal plane, but it may be provided on an inclined surface in which the vicinity of the column fixing hole is the highest and the periphery thereof is formed low. When such an inclined surface is used, even when it rains, rain water that has fallen on the upper surfaces of the columns and blocks can flow around, and the columns can be protected from corrosion due to rust and the like. In this case, it is desirable that the concave portion is formed so that the bottom portion thereof is substantially horizontal. However, even if there is a slight difference in inclination or height, leveling can be easily achieved by placing an adjustment piece on the concave portion. be able to.

続いて、本発明に係る係止部材につき説明する。本発明に係る係止部材は、支柱に取り付けられて使用するものであり、当該支柱から横方向へと突出する１又は２以上のアームからなるものである。本発明において当該アームは、支柱に対し側方又は端部から嵌装可能な帯状部材に突設させると一層好適である。   Next, the locking member according to the present invention will be described. The locking member according to the present invention is used by being attached to a support column, and is composed of one or two or more arms projecting laterally from the support column. In the present invention, it is more preferable that the arm protrudes from a belt-like member that can be fitted from the side or the end with respect to the support column.

当該係止部材は、支柱に対し側方又は当該支柱端部からの嵌装が可能であって、支柱の重量を保持できるものであれば、環状丸鋼、その他いかように構成してもよいが、例えば帯状の鋼板を、装着される支柱の外径寸法よりも小さな寸法の平面視略Ｕ字形状となるよう曲げ加工して、鋼板自体に内方向への付勢力を持たせると好適である。このように構成した場合、当該帯状部材を支柱の側方から簡単に装着でき、且つ、該帯状部材が支柱の周側面に対し密着しようとする力が働くこととなる。尚、当該帯状部材には開閉自在な「バックル」を設けて、このバックルによって該帯状部材の開口部を閉塞するようにすれば、より装着時に便利である。本発明に係る係止部材が装着される支柱は、重量の大きなものもあり、上記部材の付勢力だけでは当該支柱を高さ位置を保持できない可能性があるため、上記バックル固定を採用した場合には、係止部材を強力に固定することができる。また、当該帯状部材の内側面（支柱と接合する面）には、シート状の合成ゴムを貼設して、支柱周側面に対する摩擦度（保持力）を増加させてもよい。   As long as the locking member can be fitted to the column from the side or from the column end, and can hold the weight of the column, the round member may be configured in any manner. However, for example, it is preferable to bend a strip-shaped steel plate so that it has a substantially U shape in plan view with a size smaller than the outer diameter size of the supporting column to give the steel plate itself an inward biasing force. is there. When comprised in this way, the said strip | belt-shaped member can be easily mounted | worn from the side of a support | pillar, and the force which this strip | belt-shaped member tries to closely_contact | adhere with respect to the surrounding side surface of a support | pillar will act. In addition, it is more convenient at the time of wearing if the belt-like member is provided with a “buckle” that can be opened and closed and the opening of the belt-like member is closed by this buckle. The column to which the locking member according to the present invention is mounted may be heavy, and the height of the column may not be maintained only by the urging force of the member. The locking member can be strongly fixed. In addition, a sheet-like synthetic rubber may be attached to the inner side surface (surface to be joined to the support column) of the band-shaped member to increase the degree of friction (holding force) with respect to the support column peripheral side surface.

前記アームは、上記支柱から横方向へと突出させるものであり、前記ブロックの上面又は当該ブロックの被係止凹部と係合して、前記支柱の立設高さ位置を保持するものである。かかる機能を発揮できれば如何なる形態のものであってもよい。通常は、上記被係止凹部の形態と対応させて形成される。当該アームは、少なくとも１本有していれば支柱の設置高さ位置の設定は可能であるが、同軸線上に２本設けた場合には、支柱をブロック（被係止凹部）に載架させることが可能となり、当該支柱を揺動させるための回動軸として機能することになる。さらに当該アームを当該支柱の重心よりも高い位置に設けた場合には、当該支柱が略垂直状態に自立することとなる。仮に、当該アームを当該支柱の重心よりも低い位置に設けた場合であっても、該アームを３方向或いは４方向に向けて突出させた場合には、当該支柱が略垂直状態に自立することとなる。   The arm protrudes laterally from the support and engages with an upper surface of the block or a locked recess of the block to hold the standing height position of the support. Any form may be used as long as such a function can be exhibited. Usually, it is formed corresponding to the form of the above-mentioned locked recess. If the arm has at least one arm, the installation height position of the support column can be set. However, when two support arms are provided on the coaxial line, the support column is mounted on the block (locked recess). Thus, it functions as a rotation shaft for swinging the support column. Further, when the arm is provided at a position higher than the center of gravity of the support column, the support column becomes independent in a substantially vertical state. Even if the arm is provided at a position lower than the center of gravity of the support column, if the arm protrudes in three or four directions, the support column can stand in a substantially vertical state. It becomes.

以下、支柱立設用コンクリートブロックの最適な実施例について、図に沿って説明する。図１は実施例１に係る支柱立設用コンクリートブロック１００の斜め上方から示した図、図２は実施例１に係る支柱立設用コンクリートブロック１００の斜め下方から示した図、図３は実施例１に係る支柱立設用コンクリートブロック１００に支柱３０を挿入する状態を斜め上方から示した図、そして、図４は実施例１に係る支柱立設用コンクリートブロック１００のブロック本体１０の断面を示す図である。   Hereinafter, the optimal example of the concrete block for standing columns will be described with reference to the drawings. FIG. 1 is a diagram showing the concrete block 100 for standing columns according to the first embodiment from an oblique upper side, FIG. 2 is a diagram showing the concrete block 100 for standing columns according to the first example, and FIG. The figure which showed the state which inserts the support | pillar 30 in the concrete block 100 for standing pillars concerning Example 1 from diagonally upward, and FIG. 4 are the cross sections of the block main body 10 of the concrete block 100 for standing pillars concerning Example 1. FIG. FIG.

実施例１における支柱立設用コンクリートブロック１００は、ブロック本体１０と、延設底板２０とを有している。ブロック本体１０は、高さ５０ｃｍ、縦３０ｃｍ、横４０ｃｍの直方体に設けてある。そして、ブロック本体１０の中央に上面から下面まで貫通する支柱固定用孔１１を設けてある。支柱固定用孔１１としては、支柱３０の直径に対して約６ｃｍ程度大きい直径を有する円形断面に形成してある。尚、上記支柱固定用孔１１は、図１２に示すように、長孔（平面視楕円形）に構成してもよい。さらに、ブロック本体１０の上面における支柱固定用孔１１周縁部の２箇所には、図４（ａ）乃至（ｃ）に示すように、係止部材４０のアーム４２を受領する被係止凹部１２を設けている。本実施例の如く当該被係止凹部１２を有する支柱立設用コンクリートブロック１００は、図１０に示す型枠を用いると容易に形成できて好適である。   The concrete block 100 for standing columns in the first embodiment includes a block main body 10 and an extended bottom plate 20. The block body 10 is provided in a rectangular parallelepiped having a height of 50 cm, a length of 30 cm, and a width of 40 cm. A column fixing hole 11 is provided in the center of the block main body 10 so as to penetrate from the upper surface to the lower surface. The column fixing hole 11 is formed in a circular cross section having a diameter about 6 cm larger than the diameter of the column 30. In addition, you may comprise the said support | pillar fixing hole 11 in a long hole (planar elliptical shape), as shown in FIG. Further, at two positions on the periphery of the column fixing hole 11 on the upper surface of the block main body 10, as shown in FIGS. Is provided. The concrete block 100 for standing columns having the locked recess 12 as in this embodiment can be easily formed by using the mold shown in FIG.

一方、延設底板２０としては、ブロック本体１０の全ての側面から側方方向に延びた厚さ１０ｃｍの板状で、ブロック本体１０から１５ｃｍ延設して形成してある。この延設底板２０を設けることで、道路脇の地中に設置した場合に延設底板２０の上に埋め戻し土を載せて、この埋め戻し土の重量を利用して支柱立設用コンクリートブロック１００の移動・転倒を防止させることができるようになる。その結果、ブロック本体１０の部分の重量を軽減させることができ、かつ小さく形成することができるようになる。尚、この延設底板２０に関しては、図１１又は図１２に示すように、３方向にのみ延出させてもよい。   On the other hand, the extended bottom plate 20 is formed in a plate shape having a thickness of 10 cm extending in the lateral direction from all side surfaces of the block body 10 and extending from the block body 10 by 15 cm. By providing this extended bottom plate 20, when it is installed in the ground beside the road, the backfill soil is placed on the extended bottom plate 20, and the weight of this backfilled soil is used for the concrete block for standing columns. 100 can be prevented from moving or falling. As a result, the weight of the block main body 10 can be reduced and the block main body 10 can be formed small. The extended bottom plate 20 may be extended only in three directions as shown in FIG. 11 or FIG.

以上のように作製した支柱立設用コンクリートブロック１００は、標識やカーブミラー等を設置する付近を掘削し、底均しをする。その後、必要であれば、底盤を設置したり、砕石を敷き詰めたりして底面に基礎を作製する。その後、支柱立設用コンクリートブロック１００を載置した後、埋め戻し土で周囲を埋め戻して地中に埋めた状態で設置させる。   The concrete block 100 for standing columns prepared as described above excavates and smoothes the vicinity where a sign, a curve mirror, etc. are installed. Thereafter, if necessary, a foundation is prepared on the bottom by installing a bottom plate or laying crushed stones. Thereafter, after placing the concrete block 100 for standing upright, the surroundings are backfilled with backfilling soil and buried in the ground.

一方、本実施例に係る支柱立設用コンクリートブロック１００と組み合わされる係止部材４０を、図６（ａ）乃至（ｅ）に示す。図６（ａ）乃至（ｃ）の実施形態は、帯状の鋼板を平面視略Ｕ字形状に形成し、当該帯状部材４１の一方端部と他方端部とを結んで開口を閉塞させる「バックル４３」を有する。このバックル４３を有する係止部材４０は、重量の大きな支柱３０に対し装着されることとなる。図６（ｄ）及び（ｅ）の実施形態は、帯状の鋼板を平面視略Ｕ字形状に形成してなるものである。このバックル４３を有しない係止部材４０は、比較的重量の小さな支柱３０に対し装着されることとなる。この図６（ｄ）及び（ｅ）に示す形態おいては、説明の便宜上、両側のアーム４２が同軸延長上に配された状態にあるが、実際には、鋼板自体に内方向への付勢力を持たせているため、未だ支柱３０に装着していない時点では、前記両側のアーム４２は開口部側へと傾斜した状態となる。尚、アーム４２の形態としては、図６（ａ）及び（ｅ）の如く真っ直ぐな丸棒を設ける場合の他、図６（ｂ）及び（ｄ）の如く平板状に形成したり、或いは図６（ｃ）の如く屈曲させて強度を確保してもよい。尚、これら係止部材４０は、図８（ａ）乃至（ｃ）に示すように、帯状部材４１の下端とアーム４２の下端とを同一線上となるよう構成されているので、施工時において作業者はブロック１００側の被係止凹部１２の下限の位置を把握しやすい。この場合、支柱３０側に予め装着位置指定表示を付しておくと、施工作業が更に容易となる。   On the other hand, the locking member 40 combined with the concrete block 100 for standing columns according to the present embodiment is shown in FIGS. 6 (a) to 6 (e). In the embodiment of FIGS. 6A to 6C, a belt-shaped steel plate is formed in a substantially U shape in plan view, and one end and the other end of the belt-shaped member 41 are connected to close the opening. 43 ". The locking member 40 having the buckle 43 is attached to the heavy column 30. In the embodiment of FIGS. 6D and 6E, a belt-shaped steel plate is formed in a substantially U shape in plan view. The locking member 40 that does not have the buckle 43 is attached to the column 30 having a relatively small weight. In the form shown in FIGS. 6D and 6E, for convenience of explanation, the arms 42 on both sides are arranged on the coaxial extension. Since the force is given, the arms 42 on both sides are inclined to the opening side when not attached to the support column 30 yet. In addition, as a form of the arm 42, in addition to the case where a straight round bar is provided as shown in FIGS. 6 (a) and 6 (e), it is formed in a flat plate shape as shown in FIGS. 6 (b) and 6 (d). The strength may be secured by bending as shown in FIG. In addition, as shown in FIGS. 8A to 8C, these locking members 40 are configured so that the lower end of the belt-like member 41 and the lower end of the arm 42 are on the same line. A person can easily grasp the lower limit position of the locked recess 12 on the block 100 side. In this case, if a mounting position designation display is attached in advance to the support column 30 side, the construction work is further facilitated.

そして、図７（ａ）乃至（ｃ）に示すように、必要に応じた標識やカーブミラー等の支柱３０に係止部材４０を装着した後、図３に示すように、当該支柱３０をブロック１００の支柱固定用孔１１に挿入する。挿入された後には、図５（ａ）に示すように、アーム４２が被係止凹部１２に係合して、当該支柱３０が高さ方向に対して仮止めされた状態となる。このとき、当該アーム４２が支柱３０の重心よりも高い位置にあるときには、当該支柱３０は垂直方向に自立することとなる。即ち、平坦地に設置されたブロック１００内に支柱３０を挿入した場合には図５（ａ）に示す状態となり、勾配を有する坂道上に設置されたブロック１００内に支柱３０を挿入した場合には図５（ｂ）に示す状態となる。尚、支柱３０の重心位置を変化させる場合は、当該支柱３０の内側に砂を投入したり、或いは、当該支柱３０の下側に「おもり」を付加して行う。そして、図９に示すように、支柱３０と支柱固定用孔１１の間の隙間に砂やモルタルを流し込んで、それぞれを互いに固定する。勿論、図９の形態に限られず、当該支柱３０に標識やカーブミラーを取り付けて道路標識やカーブミラーとして使用してもよい。   Then, as shown in FIGS. 7A to 7C, after attaching the locking member 40 to the support 30 such as a sign or a curve mirror as required, the support 30 is blocked as shown in FIG. It is inserted into the 100 column fixing holes 11. After the insertion, as shown in FIG. 5A, the arm 42 is engaged with the locked recess 12, and the support column 30 is temporarily fixed in the height direction. At this time, when the arm 42 is at a position higher than the center of gravity of the support column 30, the support column 30 is self-supporting in the vertical direction. That is, when the support column 30 is inserted into the block 100 installed on a flat ground, the state shown in FIG. 5A is obtained, and when the support column 30 is inserted into the block 100 installed on a slope having a slope. Is in the state shown in FIG. In addition, when changing the gravity center position of the support | pillar 30, sand is thrown into the inside of the said support | pillar 30, or "a weight" is added to the lower side of the said support | pillar 30. And as shown in FIG. 9, sand and mortar are poured into the clearance gap between the support | pillar 30 and the support | pillar fixing hole 11, and each is fixed mutually. Of course, the present invention is not limited to the form shown in FIG. 9, and a sign or a curve mirror may be attached to the column 30 to be used as a road sign or a curve mirror.

なお、上記ブロック１００は、上記実施例に限定されることなく、図１３に示すように被係止凹部１２を当該ブロックの上面における支柱固定用孔周縁部に4箇所に設けて構成したり、或いは、図１４乃至図１６に示すように長形に構成してもよい。特に図１４に示す形態は、カーブ施工を可能とする縁石ブロックである。図１４に示す縁石ブロックは隣接する他の縁石ブロックとボルト固定して連結されて安定的に設置されるため、必ずしも地中に埋設される必要はない。   Note that the block 100 is not limited to the above-described embodiment, and is configured by providing the locked recesses 12 at four positions on the periphery of the column fixing holes on the upper surface of the block, as shown in FIG. Alternatively, it may be formed in a long shape as shown in FIGS. Especially the form shown in FIG. 14 is a curb block which enables curve construction. The curb block shown in FIG. 14 is not necessarily necessarily buried in the ground because it is connected to another adjacent curb block by bolting and stably connected.

本発明に係るコンクリートブロックは、上記実施例では専らプレキャスト型に係るものとして説明したが、本発明は特段上記構成に限定されるものではなく、施工現場に型枠を用意して、其処へコンクリートを打設することによって構成されるものとしてもよい。   The concrete block according to the present invention has been described as being exclusively related to the precast mold in the above embodiment, but the present invention is not particularly limited to the above configuration, and a formwork is prepared at the construction site, and the concrete is transferred to the concrete block. It is good also as what is comprised by placing.
