＜基礎構造＞
図１，図２を参照して、本実施の形態に係る基礎構造１について説明する。本実施の形態では、図１，図２において矢印Ａ１で示す左右方向を幅方向といい、図２において矢印Ａ２で示す方向を上下方向といい、図１において矢印Ａ３で示す方向を奥行き方向という。 <Basic structure>
The foundation structure 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. In the present embodiment, the left and right direction indicated by arrow A1 in FIGS. 1 and 2 is referred to as width direction, the direction indicated by arrow A2 in FIG. 2 is referred to as up and down direction, and the direction indicated by arrow A3 in FIG. .

本実施の形態に係る基礎構造１は、たとえば、地盤１００上に互いに間隔をあけて配置される複数の平板材２と、平板材２間に掛け渡されるガイド材３と、平板材２の上面２０とガイド材３の上端部３４との間の間隔を調整するレベル調整部４と、地盤１００とガイド材３の上端部３４との間に充填されて固化される充填材５とを備える。   The foundation structure 1 according to the present embodiment includes, for example, a plurality of flat plates 2 arranged on the ground 100 at a distance from each other, a guide member 3 bridged between the flat plates 2, and an upper surface of the flat plate 2. The level adjustment unit 4 adjusts the distance between the upper end portion 34 of the guide member 3 and the filling member 5 filled and solidified between the ground 100 and the upper end portion 34 of the guide member 3.

地盤１００は、たとえば、土、砂、砂利、砕石などを押圧することにより形成される。本実施の形態では、地盤１００の上端のレベルを厳密に調整する必要はないが、地盤１００の上端のレベルをある程度調整することで、後述するレベル調整部４のレベル調整作業を簡略化することも可能である。なお、地盤１００の上端のレベルを調節することが難しい場合は、地盤１００と平板材２との間に、たとえば、コンクリート、鉄板、合板などで形成される平板状の部材を配置することで、地盤１００の上端のレベル調節を行ってもよい。   The ground 100 is formed, for example, by pressing soil, sand, gravel, crushed stone or the like. In the present embodiment, it is not necessary to strictly adjust the level of the upper end of the ground 100, but by adjusting the level of the upper end of the ground 100 to some extent, the level adjustment operation of the level adjustment unit 4 described later can be simplified. Is also possible. If it is difficult to adjust the level of the upper end of the ground 100, a flat plate-like member made of concrete, iron plate, plywood or the like may be disposed between the ground 100 and the flat plate 2, for example. The level adjustment of the upper end of the ground 100 may be performed.

本実施の形態の基礎構造１は、たとえば、立方体形状のプレキャスト構造体１１０の下方を支持している。プレキャスト構造体１１０の上面には、プレキャスト構造体１１０を基礎構造１の長手方向の中心線に沿って配置するための目印部１１１Ａ〜１１１Ｃ（図１４）が形成されている。プレキャスト構造体１１０については、後述する。   The foundation structure 1 of the present embodiment supports, for example, the lower side of a cube-shaped precast structure 110. On the top surface of the precast structure 110, mark portions 111A to 111C (FIG. 14) for arranging the precast structure 110 along the longitudinal center line of the foundation structure 1 are formed. The precast structure 110 will be described later.

本実施の形態において、平板材２は、たとえば、４つ設けられ、地盤１００上に等間隔に配置されている。４つの平板材２は、長尺状に延びる４つのガイド材３によってそれぞれ連結されている。   In the present embodiment, four flat plates 2 are provided, for example, and arranged at equal intervals on ground 100. The four flat plates 2 are connected by four long guide members 3 respectively.

まず、図３を参照して、平板材２について説明する。図３においても、矢印Ａ１で示す左右方向を幅方向といい、矢印Ａ２で示す方向を上下方向といい、矢印Ａ３で示す方向を奥行き方向という。   First, the flat plate 2 will be described with reference to FIG. Also in FIG. 3, the left and right direction indicated by the arrow A1 is referred to as the width direction, the direction indicated by the arrow A2 is referred to as the up and down direction, and the direction indicated by the arrow A3 is referred to as the depth direction.

平板材２は、たとえば、複数の辺を有する矩形形状である。具体的には、平板材２は、コンクリートで形成された中実の平面視略正方形形状であり、４つの辺の第１辺２３ａ〜第４辺２３ｄを有している。平板材２は、プレキャスト構造体１１０側に位置する上面２０と、地盤１００側に位置する底面２１とを有している。平板材２は、一定の厚みを有している。   The flat plate material 2 is, for example, a rectangular shape having a plurality of sides. Specifically, the flat plate material 2 is a solid substantially square shape in plan view formed of concrete, and has first to fourth sides 23a to 23d of four sides. The flat plate material 2 has an upper surface 20 located on the precast structure 110 side and a bottom surface 21 located on the ground 100 side. The flat plate 2 has a constant thickness.

平板材２の上面２０には、被係合部２２が設けられている。具体的には、被係合部２２は、上面２０から底面２１に向かって延びる穴部と、穴部の内部に埋め込まれる高ナット（長いナット）とを含む。被係合部２２は、高ナットに代えて、穴の壁面にネジ溝を含んでいてもよい。また、被係合部２２は、平板材２の上面２０から底面２１に向かって延びているが、平板材２を貫通していてもよいし、貫通していなくてもよい。被係合部２２と係合する係合部３５については、後述する。   An engaged portion 22 is provided on the upper surface 20 of the flat plate material 2. Specifically, the engaged portion 22 includes a hole extending from the top surface 20 toward the bottom 21 and a high nut (long nut) embedded inside the hole. The engaged portion 22 may include a thread groove on the wall surface of the hole instead of the high nut. Moreover, although the to-be-engaged part 22 is extended toward the bottom face 21 from the upper surface 20 of the flat plate material 2, the flat plate material 2 may be penetrated and it is not necessary to penetrate. The engaging portion 35 engaged with the engaged portion 22 will be described later.

被係合部２２は、たとえば、平板材２の互いに直交する２つの辺の第１辺２３ａ，第２辺２３ｂに沿ってそれぞれ２つずつ整列して設けられている。平板材２に形成される被係合部２２は、すべて同一形状であるが、説明の便宜上、図３（ｂ）において、第１辺２３ａに沿って設けられ、第１辺２３ａと第２辺２３ｂとが交わる角部側に設けられる被係合部を第１被係合部２２ａとする。第２辺２３ｂに沿って設けられ、第１辺２３ａと第２辺２３ｂとが交わる角部側に設けられる被係合部を第２被係合部２２ｂとする。第１辺２３ａに沿って設けられ、第１被係合部２２ａと隣り合う被係合部を第３被係合部２２ｃとする。さらに、第２辺２３ｂに沿って設けられ、第２被係合部２２ｂと隣り合う被係合部を第４被係合部２２ｄとする。   The engaged portions 22 are provided, for example, two each in alignment along the first side 23 a and the second side 23 b of the two sides of the flat plate 2 orthogonal to each other. The engaged portions 22 formed on the flat plate member 2 have the same shape, but for convenience of explanation, in FIG. 3B, they are provided along the first side 23a, and the first side 23a and the second side Let the to-be-engaged part provided in the corner | angular part side which 23b crosses be 1st to-be-engaged part 22a. An engaged portion provided along the second side 23 b and provided on the corner side where the first side 23 a and the second side 23 b intersect is referred to as a second engaged portion 22 b. An engaged portion provided along the first side 23 a and adjacent to the first engaged portion 22 a is referred to as a third engaged portion 22 c. Furthermore, an engaged portion provided along the second side 23b and adjacent to the second engaged portion 22b is referred to as a fourth engaged portion 22d.

この場合、第２辺２３ｂから第１被係合部２２ａまでの間隔をＬ１、第１被係合部２２ａから第３被係合部２２ｃまでの間隔をＬ２、第３被係合部２２ｃから第３辺２３ｃまでの間隔をＬ３とすると、以下の関係式が成立する。また、第１辺２３ａの寸法および第２辺２３ｂの寸法は、略同一であるため、第４辺２３ｄから第４被係合部２２ｄまでの間隔をＬ１、第４被係合部２２ｄから第２被係合部２２ｂまでの間隔をＬ２、第２被係合部２２ｂから第１辺２３ａまでの間隔をＬ３としても、同様の関係式が成立する。   In this case, the distance from the second side 23b to the first engaged portion 22a is L1, the distance from the first engaged portion 22a to the third engaged portion 22c is L2, and the distance from the third engaged portion 22c to Assuming that the distance to the third side 23c is L3, the following relational expression is established. Further, since the dimensions of the first side 23a and the dimensions of the second side 23b are substantially the same, the distance from the fourth side 23d to the fourth engaged portion 22d is L1, and the distance from the fourth engaged portion 22d to the fourth engaged portion 22d is The same relational expression holds even when the distance to the second engaged portion 22b is L2 and the distance from the second engaged portion 22b to the first side 23a is L3.

Ｌ１：Ｌ２：Ｌ３＝１：２：１   L1: L2: L3 = 1: 2: 1

このように、４つの被係合部２２を間隔をあけて設けることで、図１５の平板材２Ｂ，２Ｄに示すように、ガイド材３が直交するように配置される場合であっても、ガイド材３の端部が干渉し合うことがない。   As described above, even when the guide members 3 are arranged orthogonally to each other as shown in the flat plates 2B and 2D of FIG. The ends of the guide member 3 do not interfere with each other.

次に、図４を参照して、ガイド材３について説明する。上述したように、ガイド材３は、複数の平板材２のうち隣り合う２つの平板材２間に掛け渡される。ガイド材３は、水平方向に延在する上端部３４を有する。具体的には、ガイド材３は、たとえば、断面視略Ｌ字形状の長尺状の部材であり、係合部３５が貫通する取付部３１と、取付部３１から上方に立ち上がり、上端部３４を形成する立ち上がり部３３とを含む。取付部３１と立ち上がり部３３とは、たとえば、略垂直であってもよい。ガイド材３は、たとえば、長尺状の薄板部材を長手方向に折り曲げて形成されていてもよい。取付部３１の長手方向の両端部には、係合部３５が挿通する挿通穴３２がそれぞれ設けられている。本実施の形態では、係合部３５は、たとえば、ボルトであり、上述した被係合部２２の高ナットに係合する。なお、取付部３１には、その長手方向両端部以外にも、挿通穴３２が複数設けられていてもよい。   Next, the guide member 3 will be described with reference to FIG. As described above, the guide member 3 is bridged between two adjacent flat plates 2 among the plurality of flat plates 2. The guide member 3 has an upper end 34 extending in the horizontal direction. Specifically, the guide member 3 is, for example, an elongated member having a substantially L-shaped cross sectional view, and the mounting portion 31 through which the engaging portion 35 passes and the upper portion 34 rise from the mounting portion 31. And a rising portion 33 that forms the The attachment portion 31 and the rising portion 33 may be, for example, substantially vertical. The guide member 3 may be formed, for example, by bending a long thin plate member in the longitudinal direction. Insertion holes 32 through which the engagement portion 35 is inserted are respectively provided at both end portions in the longitudinal direction of the attachment portion 31. In the present embodiment, the engaging portion 35 is, for example, a bolt, and engages with the high nut of the engaged portion 22 described above. Note that a plurality of insertion holes 32 may be provided in the mounting portion 31 in addition to both longitudinal end portions.

図２，図１１を参照して、本実施の形態のレベル調整部４は、平板材２に取り付けられ、平板材２の上面２０とガイド材３の上端部３４との間の間隔を調整する。つまり、レベル調整部４は、ガイド材３の上端部３４の水平レベルおよび高さレベルを調整するものである。具体的には、レベル調整部４は、平板材２の上面２０に設けられた被係合部２２と、ガイド材３に取り付けられ、被係合部２２に係合する係合部３５と、ガイド材３の取付部３１と平板材２との間に設けられるスペーサー４１とを含む。   Referring to FIGS. 2 and 11, level adjustment unit 4 of the present embodiment is attached to flat plate member 2, and adjusts the distance between upper surface 20 of flat plate member 2 and upper end portion 34 of guide member 3. . That is, the level adjustment unit 4 adjusts the horizontal level and the height level of the upper end portion 34 of the guide member 3. Specifically, the level adjustment unit 4 includes an engaged portion 22 provided on the upper surface 20 of the flat plate 2 and an engaging portion 35 attached to the guide member 3 and engaged with the engaged portion 22; It includes a spacer 41 provided between the attachment portion 31 of the guide member 3 and the flat plate member 2.

スペーサー４１は、ガイド材３の上端部３４の高さ位置を調節できるものであればよく、スペーサー４１としては、たとえば、プラレベル（登録商標）、ライナープレートなどが挙げられる。本実施の形態では、スペーサー４１は、楔形の形状であり、一端が薄く、他端に至るにしたがって厚い形状である。スペーサー４１は、たとえば、２つ設けられ、係合部（ボルト）３５の柱部を挟んで、ガイド材３の取付部３１と平板材２との間に取り付けられている。   The spacer 41 may be any one as long as it can adjust the height position of the upper end portion 34 of the guide member 3, and the spacer 41 may, for example, be PLA LEVEL (registered trademark), a liner plate or the like. In the present embodiment, the spacer 41 has a wedge shape, one end is thin, and the other end is thick. For example, two spacers 41 are provided, and are attached between the attachment portion 31 of the guide member 3 and the flat plate member 2 with the pillar portion of the engagement portion (bolt) 35 interposed therebetween.

充填材５は、地盤１００とガイド材３の上端部３４との間に充填されて固化される。充填材５としては、たとえば、空練モルタルであることが好ましく、水分を含んだペースト状ではないモルタル、土、砂、砂利、砕石などが挙げられる。これにより、水分を含んだペースト状のモルタルなどと比較して、施工スピードを向上させることができる。なお、ガイド材３の隙間に充填材５を充填する場合は、ガイド材３の立ち上がり部３３に板材を沿わせてもよい。また、充填材５の高さが高い場合は、充填材５の沈下を防ぐために、一旦締め固めた後に均してもよい。   The filler 5 is filled between the ground 100 and the upper end 34 of the guide member 3 and solidified. The filler 5 is preferably, for example, an air-filled mortar, and examples thereof include non-pasty mortar containing water, soil, sand, gravel, crushed stone, and the like. Thereby, compared with the paste-like mortar containing water, etc., construction speed can be improved. In addition, when filling the filler 5 in the gap of the guide member 3, the plate member may be made to stand along the rising portion 33 of the guide member 3. Moreover, when the height of the filler 5 is high, in order to prevent the sinking of the filler 5, it may be leveled after being once compacted.

＜基礎構造の製造方法＞
図５〜図１３を参照して、基礎構造１の製造方法の一例について説明する。 <Method of manufacturing foundation structure>
An example of a method of manufacturing the foundation structure 1 will be described with reference to FIGS. 5 to 13.

まず、砂や砂利などを敷き込み、転圧を行って地盤１００を形成する。地盤１００の上端の水平レベルおよび高さレベルの調整は、厳密に行う必要はなく、ある程度行うだけで足りる。図５，図６に示すように、平板材２を４つ用意し、地盤１００上に等間隔に配置する。本実施の形態では、平板材２の被係合部２２が設けられている２つの辺が外方を向いて配置されている。この場合、それぞれの平板材２は、水平レベルおよび高さレベルの調整を厳密に行う必要はなく、地盤１００上に配置されていればよい。   First, sand, gravel, etc. are spread and compacted to form the ground 100. The adjustment of the horizontal level and height level of the upper end of the ground 100 does not have to be performed strictly, but only to some extent. As shown in FIGS. 5 and 6, four flat plates 2 are prepared and arranged on the ground 100 at equal intervals. In the present embodiment, the two sides on which the engaged portion 22 of the flat plate material 2 is provided are disposed facing outward. In this case, the respective flat plate members 2 do not have to be precisely adjusted in the horizontal level and the height level, and may be disposed on the ground 100.

図７に示すように、互いに隣り合う平板材２の間に、地盤１００を形成する砕石を充填する。具体的には、複数の平板材２の上面２０以外を全て砕石で埋める。ここで、地盤１００は、砕石だけではなく、たとえば、土、砂、砂利、コンクリート、アスファルトなどを含む。なお、地盤１００上に平板材２が入る大きさの穴を掘り、その穴の中に平板材２を埋めて、平板材２の上面２０だけを露出させてもよい。これにより、隣り合う平板材２の間に充填材５を充填する必要がないため、充填材５の量を減らすことができる。   As shown in FIG. 7, crushed stones forming the ground 100 are filled between the flat plates 2 adjacent to each other. Specifically, all but the upper surfaces 20 of the plurality of flat plates 2 are filled with crushed stone. Here, the ground 100 includes not only crushed stone but, for example, soil, sand, gravel, concrete, asphalt and the like. Alternatively, a hole may be excavated on the ground 100 so as to receive the flat plate 2, and the flat plate 2 may be embedded in the hole to expose only the upper surface 20 of the flat plate 2. Thereby, the amount of the filler 5 can be reduced because it is not necessary to fill the filler 5 between adjacent flat plates 2.

図８，図９に示すように、４つの平板材２を４つのガイド材３で連結する。具体的には、ガイド材３の取付部３１を平板材２の上面に配置する。これにより、ガイド材３の立ち上がり部３３は、平板材２の上面２０から上方に立ち上がる。さらに、ガイド材３の挿通穴３２と平板材２の被係合部２２とを係合部（ボルト）３５で貫通させ、ガイド材３を平板材２に仮止めする。   As shown in FIGS. 8 and 9, four flat plates 2 are connected by four guide members 3. Specifically, the mounting portion 31 of the guide member 3 is disposed on the upper surface of the flat plate member 2. As a result, the rising portion 33 of the guide member 3 rises upward from the upper surface 20 of the flat plate member 2. Furthermore, the insertion hole 32 of the guide member 3 and the engaged portion 22 of the flat plate member 2 are penetrated by the engaging portion (bolt) 35, and the guide member 3 is temporarily fixed to the flat plate member 2.

図１０，図１１に示すように、ガイド材３の取付部３１と平板材２の上面２０との間に２つのスペーサー４１を設けて、ガイド材３の上端部３４の高さレベルおよび水平レベルを調整する。図１０（ａ）は紙面上の右側に位置するガイド材３の上端部３４のレベル調整を行った状態を示す側面図であり、（ｂ）は紙面上の左側に位置するガイド材３の上端部３４のレベル調整を行った状態を示す側面図である。   As shown in FIGS. 10 and 11, two spacers 41 are provided between the mounting portion 31 of the guide member 3 and the upper surface 20 of the flat plate member 2 so that the height level and horizontal level of the upper end portion 34 of the guide member 3 can be obtained. Adjust the FIG. 10A is a side view showing a state in which the level adjustment of the upper end portion 34 of the guide member 3 positioned on the right side in the drawing is performed, and FIG. 10B is an upper end of the guide member 3 positioned on the left It is a side view which shows the state which performed the level adjustment of the part 34. FIG.

ガイド材３の上端部３４の高さ位置を、施工現場において測量機等を用いてレベル出しされた正確な高さ位置に合わせる。まず、図１０（ａ）に示すように、紙面上の右側に位置するガイド材３の上端部３４の高さ位置を、計測器などを用いてレベル出しされた正確な高さ位置に合わせる。それと共に、ガイド材３の上端部３４上に水準器を載置して傾きをチェックし、傾いていれば水平となるようにスペーサー４１で調整し、ガイド材３の傾きを微調整する。なお、図１０（ａ），図１０（ｂ）において、ガイド材３と平板材２との間には、スペーサー４１を設けているが、あらかじめ正確な高さとなっている場合には、スペーサー４１を設ける必要はない。   The height position of the upper end portion 34 of the guide member 3 is adjusted to the accurate height position leveled using a surveying instrument or the like at the construction site. First, as shown in FIG. 10A, the height position of the upper end portion 34 of the guide member 3 positioned on the right side of the paper surface is adjusted to an accurate height position leveled using a measuring instrument or the like. At the same time, a level is placed on the upper end portion 34 of the guide member 3 to check its inclination, and if it is inclined, it is adjusted by the spacer 41 so as to be horizontal, and the inclination of the guide member 3 is finely adjusted. In FIGS. 10 (a) and 10 (b), the spacer 41 is provided between the guide member 3 and the flat plate member 2. However, in the case where the spacer 41 has an accurate height in advance, the spacer 41 is provided. There is no need to

次に、紙面上の左側に位置するガイド材３の上端部３４の高さ位置を正確な高さ位置に合わせる。図１０（ａ）に示すように、レベル出しされた正確な高さ位置（本実施の形態では、紙面上の右側に位置するガイド材３の上端部３４）と、紙面上の左側に位置するガイド材３の上端部３４の位置とのずれは、寸法Ｈである。図１０（ｂ）に示すように、左側に位置するガイド材３の取付部３１と平板材２の上面２０との間にスペーサー４１を押し込んで、スペーサー４１の厚みのある部分で取付部３１を支持させ、寸法Ｈだけガイド材３の上端部３４を上昇させて、正確なレベルに合わせる。それと共に、上述と同様の方法で水平レベルも調整する。   Next, the height position of the upper end portion 34 of the guide member 3 positioned on the left side on the paper surface is adjusted to the correct height position. As shown in FIG. 10 (a), it is positioned on the right side on the paper surface with the accurate height position (in the present embodiment, the upper end 34 of the guide member 3 located on the right side on the paper surface). The deviation from the position of the upper end portion 34 of the guide member 3 is the dimension H. As shown in FIG. 10B, the spacer 41 is pushed between the attachment portion 31 of the guide member 3 positioned on the left side and the upper surface 20 of the flat plate member 2, and the attachment portion 31 is Support and raise the top 34 of the guide 3 by the dimension H to bring it to the correct level. At the same time, the horizontal level is also adjusted in the same manner as described above.

このように、レベル調整部４で平板材２の上面２０とガイド材３の上端部３４との間隔を調整することで、左側に位置するガイド材３の上端部３４と、右側に位置するガイド材３の上端部３４との水平レベルおよび高さレベルを調節することができる。このような手順で、他のガイド材３の上端部３４のレベル出しを行う。   Thus, by adjusting the distance between the upper surface 20 of the flat plate 2 and the upper end 34 of the guide 3 by the level adjustment unit 4, the upper end 34 of the guide 3 located on the left and the guide located on the right The horizontal level and height level with the upper end 34 of the material 3 can be adjusted. In such a procedure, leveling of the upper end portion 34 of the other guide member 3 is performed.

図１２，図１３に示すように、地盤１００とガイド材３の上端部３４との間に充填材５を充填させる。次に、対向するガイド材３に掛け渡せるだけの長さを有する長尺状の板（図示せず）を準備する。準備した長尺状板を、対向するガイド材３に対して直交するように、ガイド材３の上端部３４に掛け渡す。さらに、長尺状板をガイド材３の長手方向に沿って移動させて、上端部３４の高さ位置よりも上方に盛り上がっている充填材５を取り除いたり、上端部３４の高さ位置に達しない部分に充填材５を移動させたりして、充填材５の高さ位置をガイド材３の上端部３４の高さ位置と同様になるように均していく。   As shown in FIGS. 12 and 13, the filler 5 is filled between the ground 100 and the upper end 34 of the guide member 3. Next, a long plate (not shown) having a length sufficient to be stretched over the opposing guide members 3 is prepared. The prepared long plate is stretched over the upper end portion 34 of the guide member 3 so as to be orthogonal to the opposing guide member 3. Furthermore, the long plate is moved along the longitudinal direction of the guide member 3 to remove the filler material 5 protruding upward from the height position of the upper end 34 or to reach the height position of the upper end 34 The filler 5 is moved to the non-portion, and the height position of the filler 5 is leveled so as to be the same as the height position of the upper end portion 34 of the guide member 3.

これにより、ガイド材３の上端部３４の高さレベルおよび水平レベルは、既に所定のレベルに保たれているため、充填材５をガイド材３の上端部３４の高さレベルまで充填させて上面を均すだけで、基礎構造１を所定の水平レベルおよび高さレベルに保つことができる。   Thereby, the height level and the horizontal level of the upper end portion 34 of the guide member 3 are already maintained at the predetermined level, and the filler 5 is filled up to the height level of the upper end portion 34 of the guide member 3 The foundation structure 1 can be kept at predetermined horizontal and height levels simply by

従来は、作業者がレベル出しを行いながら、コテやトンボなどで充填材５の上面を均す必要があり、施工時間がかかっていた。しかし、ガイド材３の上端部３４上には、何も取り付けられないため、長尺状板をガイド材３の上端部３４上に掛け渡し、長尺状板をガイド材３に沿って移動させるという簡易な方法で充填材５の上面を水平に均すことができる。このように、本実施の形態によれば、施工時間を短縮することができ、省施工で容易にレベル調整を行うことができる。   Conventionally, it has been necessary for the operator to level the top surface of the filler 5 with a trowel or a dragonfly while leveling, which requires a long construction time. However, since nothing is attached on the upper end portion 34 of the guide member 3, the elongated plate is stretched over the upper end portion 34 of the guide member 3 and the elongated plate is moved along the guide member 3. The upper surface of the filler 5 can be leveled horizontally by a simple method. As described above, according to the present embodiment, the construction time can be shortened, and level adjustment can be easily performed with reduced construction.

＜プレキャスト構造体＞
次に、図１４を参照して、基礎構造１上にプレキャスト構造体１１０の設置方法について説明する。図１４は、形状の異なる複数のプレキャスト構造体１１０Ａ〜１１０Ｃを基礎構造１上に載置した状態を示す平面図である。なお、図１３において、基礎構造１の図示は省略している。また、図１４においても、矢印Ａ１で示す方向を幅方向、矢印Ａ３で示す奥行き方向を長手方向とする。 <Precast structure>
Next, with reference to FIG. 14, a method of installing the precast structure 110 on the foundation structure 1 will be described. FIG. 14 is a plan view showing a state in which a plurality of precast structures 110A to 110C having different shapes are mounted on the basic structure 1. FIG. In addition, illustration of the basic structure 1 is abbreviate | omitted in FIG. Also in FIG. 14, the direction indicated by the arrow A1 is taken as the width direction, and the depth direction shown by the arrow A3 is taken as the longitudinal direction.

プレキャスト構造体１１０Ａ〜１１０Ｃの上面には、その幅方向の中央部に目印部１１１Ａ〜１１１Ｃがそれぞれ形成されている。目印部１１１Ａ〜１１１Ｃは、たとえば、切り込み、印字、段差などにより付されていればよい。基礎構造１の上方にプレキャスト構造体１１０Ａ〜１１０Ｃを載置するには、まず、基礎構造１の上方に、図１４において一点鎖線で示す水糸１２０を張る。この水糸１２０は、基礎構造１の幅方向中央部において、長手方向に延在する。プレキャスト構造体１１０の目印部１１１Ａ〜１１１Ｃと水糸１２０とが一致するように、プレキャスト構造体１１０Ａ〜１１０Ｃを基礎構造１上に載置する。   Mark portions 111A to 111C are respectively formed at the center in the width direction on the upper surfaces of the precast structures 110A to 110C. The mark portions 111A to 111C may be attached, for example, by cutting, printing, or steps. In order to place the precast structures 110A to 110C above the foundation structure 1, first, a water thread 120 indicated by an alternate long and short dash line in FIG. 14 is stretched above the foundation structure 1. The water thread 120 extends in the longitudinal direction at the widthwise center of the foundation structure 1. The precast structures 110A to 110C are placed on the foundation structure 1 so that the mark portions 111A to 111C of the precast structure 110 and the water threads 120 coincide with each other.

本実施の形態に係る基礎構造１によれば、プレキャスト構造体１１０Ａ〜１１０Ｃの目印部１１１Ａ〜１１１Ｃを基礎構造１に張った水糸１２０に沿わせて配置するだけで、基礎構造１の中心線上にプレキャスト構造体１１０を容易に載置することができ、別途、墨出しを行う必要がなく、プレキャスト構造体１１０Ａ〜１１０Ｃの位置合わせ、いわゆる通り出しを容易に行なうことができる。これにより、形状の異なる複数のプレキャスト構造体１１０Ａ〜１１０Ｃを基礎構造１上に配置するための施工時間を短縮することが可能である。   According to the foundation structure 1 according to the present embodiment, the center line of the foundation structure 1 can be obtained simply by arranging the mark portions 111A to 111C of the precast structures 110A to 110C along the water thread 120 stretched on the foundation structure 1 The precast structure 110 can be easily mounted, and it is not necessary to separately perform marking, and alignment of the precast structures 110A to 110C, that is, so-called run-out can be easily performed. Thereby, it is possible to shorten the construction time for arranging a plurality of precast structures 110A to 110C having different shapes on the foundation structure 1.
