Description

本発明は、柱脚アンカー構造体、架台、および柱脚アンカー構造体の設計方法に関する。 The present invention relates to a column base anchor structure, a mounting base, and a method for designing a column base anchor structure.

従来、地面に打設されたコンクリートに建物用柱脚を設置するための柱脚アンカー構造体が知られている（例えば、特許文献１）。柱脚アンカー構造体は、建物の柱に接合されるベースプレートを基礎コンクリートに固定する構造体である。 Conventionally, a column base anchor structure for installing a building column base in concrete poured into the ground is known (for example, Patent Document 1). The column base anchor structure is a structure that fixes a base plate joined to a column of a building to the foundation concrete.

柱脚アンカー構造体は、均しコンクリート上に配置される架台、架台上に設置される形板、およびベースプレートを基礎コンクリートに固定するためのアンカーボルトなどから構成される。 The column base anchor structure is composed of a base that is placed on the leveled concrete, a form plate that is installed on the base, and anchor bolts for fixing the base plate to the foundation concrete.

架台、および形板は、あらかじめ規格によってその仕様が定められており、ベースプレートの種類およびサイズなどの仕様に合わせて選択される。また、柱脚アンカー構造体を構成するこれらの部品は、一般に、建設現場で組み立てられる。 The specifications of the mounting base and the form plate are determined in advance by standards, and are selected according to the specifications of the type and size of the base plate. Furthermore, these parts that make up the column base anchor structure are generally assembled at the construction site.

特開２０１８－５３５６３号公報JP 2018-53563 A

設計時に選択された形板とは異なる形板が建設現場に誤って納入された場合、建設現場では、これに気づかずに形板を架台に取り付けてしまうおそれがある。設計時に選択された形板とは異なる形板が架台に取り付けられてしまうと、柱脚アンカー構造体のアンカーボルトの位置とベースプレートに形成されたボルト穴の位置とが一致しなくなるため、基礎コンクリートに対してベースプレートをアンカーボルトで固定できなくなる。 If a form plate different from the one selected at the time of design is mistakenly delivered to the construction site, there is a risk that the form plate will be attached to the frame at the construction site without being noticed. If a form plate different from the one selected at the time of design is attached to the frame, the position of the anchor bolt of the column base anchor structure will not match the position of the bolt hole formed in the base plate, and the base plate will not be able to be fixed to the foundation concrete with the anchor bolt.

本発明は、柱脚アンカー構造体を構成する形板が設計時に選択されたものであるか否かを製造現場において判断することを可能にする柱脚アンカー構造体、架台、および柱脚アンカー構造体の設計方法を提供することを目的とする。 The present invention aims to provide a column base anchor structure, a stand, and a design method for a column base anchor structure that makes it possible to determine at the manufacturing site whether the form plate that constitutes the column base anchor structure is the one selected at the time of design.

本発明に係る柱脚アンカー構造体の設計方法は、規格によって仕様が定められた複数の形板から選択された一の形板と、一の形板を支持する架台と、を備える柱脚アンカー構造体の設計方法であって、架台は、形板を支持する一対の支持部を有し、一対の支持部の上面には凸部が設けられ、形板は、一対の支持部で支持される一対の被支持部を有し、規格は、一対の被支持部の間隔が段階的に大きくなるように形板の仕様を定めるものであり、間隔が第１の間隔である仕様、間隔が第１の間隔よりも１段階大きい第２の間隔である仕様、間隔が第２の間隔よりも１段階大きい第３の間隔である仕様を含み、一対の支持部に設けられた凸部の外側端の間隔を、第１の間隔以上、かつ第２の間隔以下に定めることと、一対の支持部の外側端の間隔を、第２の間隔以上、かつ第３の間隔以下に定めることを含む。 The design method of the column base anchor structure according to the present invention is a design method of the column base anchor structure comprising a form plate selected from a plurality of form plates whose specifications are determined by a standard, and a base supporting the form plate, the base having a pair of support parts supporting the form plate, a protrusion on the upper surface of the pair of support parts, the form plate having a pair of supported parts supported by the pair of support parts, the standard determines the specifications of the form plate so that the distance between the pair of supported parts increases in stages, including a specification in which the distance is a first distance, a specification in which the distance is a second distance one step larger than the first distance, and a specification in which the distance is a third distance one step larger than the second distance, and includes determining the distance between the outer ends of the protrusions provided on the pair of support parts to be equal to or greater than the first distance and equal to or less than the second distance, and determining the distance between the outer ends of the pair of support parts to be equal to or greater than the second distance and equal to or less than the third distance.

本発明によれば、柱脚アンカー構造体を構成する形板が設計時に選択されたものであるか否かを建設現場において判断することが可能になる。特に、架台に剛性が要求され、支持部を構成する部材も断面性能が大きなものが選択されるなどにより、結果的に支持部の幅が大きくなってしまうような場合には、段階が小さい間隔の仕様の形板が架台に載ることが可能となるので、これを防止することができる。 According to the present invention, it is possible to determine at the construction site whether the form plate that constitutes the column base anchor structure is the one selected at the time of design. In particular, in cases where the support part ends up being wide because the frame requires rigidity and the members that constitute the support part have a large cross-sectional performance, this can be prevented by making it possible to place a form plate with a small step interval on the frame.

［第１の実施形態］
以下、本発明の第１の実施形態につき図面を参照して説明する。なお、本発明は、この実施形態に限定されないことはいうまでもない。 [First embodiment]

［柱脚アンカー構造体の概要］
柱脚アンカー構造体の概要について説明する。 [Outline of column base anchor structure]
An overview of the column base anchor structure will be described.

図１は、柱脚アンカー構造体の斜視図である。柱脚アンカー構造体１は、建物の柱を基礎コンクリート上に固定するための構造体である。柱脚アンカー構造体１は、架台２、およびアンカーフレーム３を備えている。 Figure 1 is a perspective view of a column base anchor structure. The column base anchor structure 1 is a structure for fixing a building column onto a concrete foundation. The column base anchor structure 1 includes a base 2 and an anchor frame 3.

架台２は、均しコンクリート上に載置され、アンカーフレーム３を支持する部材である。架台２は、支柱２１、横部材２２、および台座２３を有する。 The stand 2 is placed on the leveled concrete and is a member that supports the anchor frame 3. The stand 2 has a support 21, a cross member 22, and a base 23.

支柱２１は、均しコンクリートに対して垂直に配置される部材である。支柱２１には、例えば、材軸方向に長い山形鋼などの鋼材が用いられる。 The pillars 21 are members that are placed perpendicular to the leveled concrete. For the pillars 21, steel materials such as angle iron that are long in the axial direction are used.

横部材２２は、支柱２１の上端部に固定されて、各支柱２１を連結する。横部材２２には、例えば、材軸方向に長い山形鋼などの鋼材が用いられる。また、横部材２２は、支持部２２１を有している。 The cross members 22 are fixed to the upper ends of the columns 21 to connect the columns 21 together. The cross members 22 are made of steel, such as angle iron, that is long in the axial direction. The cross members 22 also have support parts 221.

支持部２２１は、互いに平行に配置された一対の横部材２２の上端から水平方向かつ互いに離間する方向に突出する部分である。この一対の支持部２２１の上面は下形板３１の下面に当接し、アンカーフレーム３を支持する。 The support parts 221 are parts that protrude horizontally and away from each other from the upper ends of a pair of cross members 22 that are arranged parallel to each other. The upper surfaces of the pair of support parts 221 abut against the lower surface of the lower plate 31, supporting the anchor frame 3.

架台２に剛性が要求され、支持部２２１を構成する横部材２２も断面性能が大きなものが選択されるなどによって、結果的に支持部２２１の幅が大きくなってしまうような場合ある。このような場合には、段階が低い小さい間隔の仕様の形板が架台２に載ることが可能となってしまう。これを防止するために、支持部２２１に凸部２２２が設けられる。 When rigidity is required for the stand 2 and the cross members 22 that make up the support part 221 are selected to have a large cross-sectional performance, the width of the support part 221 may end up being large. In such a case, it becomes possible for a form plate with a low step and small spacing to be placed on the stand 2. To prevent this, a protrusion 222 is provided on the support part 221.

凸部２２２は支持部２２１の上面に設けられる。凸部２２２は、架台２とアンカーフレーム３とが設計時に選択された、互いに対応するものであるか否かを判断するための目印として用いられる。また、凸部２２２は、支持部２２１上にアンカーフレーム３が載置される際に位置決め部材として機能する。 The protrusion 222 is provided on the upper surface of the support portion 221. The protrusion 222 is used as a mark for determining whether the pedestal 2 and the anchor frame 3 correspond to each other as selected at the time of design. The protrusion 222 also functions as a positioning member when the anchor frame 3 is placed on the support portion 221.

凸部２２２は、例えば、平面視で矩形に形成された板部材である。凸部２２２は、各支持部２２１上に、例えば、２つ設けられる。 The protrusions 222 are, for example, plate members formed in a rectangular shape in a plan view. For example, two protrusions 222 are provided on each support portion 221.

支持部２２１にアンカーフレーム３が載置された状態において、支持部２２１の上面には、アンカーフレーム３と支持部２２１とを接合するための溶接代が確保されている。この溶接代については後述する。 When the anchor frame 3 is placed on the support part 221, a welding allowance is provided on the upper surface of the support part 221 to join the anchor frame 3 and the support part 221. This welding allowance will be described later.

支持部２２１の長手方向の長さは、支持部２２１にアンカーフレーム３が載置された際に、アンカーボルト３２の下形板３１より下方の部分が支持部２２１に干渉しないように形成される。具体的には、支持部２２１は、長手方向の長さが横部材２２の長手方向の長さより短く、両端部が切り欠かれたように形成されている。 The longitudinal length of the support part 221 is formed so that when the anchor frame 3 is placed on the support part 221, the part of the anchor bolt 32 below the lower plate 31 does not interfere with the support part 221. Specifically, the longitudinal length of the support part 221 is shorter than the longitudinal length of the cross member 22, and both ends are formed so as to be cut out.

台座２３は、支柱２１の下端部に固定される部材である。台座２３は、各支柱２１をその下端部において連結し、架台２の安定性を確保する。 The base 23 is a member fixed to the lower end of the support 21. The base 23 connects each support 21 at its lower end, ensuring the stability of the stand 2.

アンカーフレーム３は、架台２によって支持される部材である。アンカーフレーム３は、下形板３１、アンカーボルト３２、およびナット３３、３４を有している。 The anchor frame 3 is a member supported by the stand 2. The anchor frame 3 has a lower plate 31, anchor bolts 32, and nuts 33 and 34.

下形板３１は、架台２によって支持される矩形状の鉄板である。下形板３１には、中央に矩形の開口３１１が形成される。つまり、下形板３１は、４つの帯状の板部材である被支持部３１２が枠状に連結された形状に形成されている。下形板３１は、複数の長方形の鉄板を溶接などにより枠状に接合して形成してもよい。４つの被支持部３１２は、対応する架台２の４つの支持部２２１によって支持される。４つの被支持部３１２のうち、開口３１１を挟んで互いに対向する一対の被支持部３１２が、本願発明の一対の被支持部に相当する。なお、下形板３１の形状、および下形板３１に形成される開口３１１の形状は矩形に限られず、他の形状であってもよい。例えば、対向する一対の被支持部３１２は、必ずしも互いに平行に配置されていなくてもよい。 The lower plate 31 is a rectangular iron plate supported by the frame 2. The lower plate 31 has a rectangular opening 311 in the center. In other words, the lower plate 31 is formed in a shape in which four supported parts 312, which are strip-shaped plate members, are connected in a frame shape. The lower plate 31 may be formed by joining a plurality of rectangular iron plates into a frame shape by welding or the like. The four supported parts 312 are supported by the four supporting parts 221 of the corresponding frame 2. Of the four supported parts 312, a pair of supported parts 312 facing each other with the opening 311 between them corresponds to a pair of supported parts in the present invention. Note that the shape of the lower plate 31 and the shape of the opening 311 formed in the lower plate 31 are not limited to a rectangle and may be other shapes. For example, the pair of opposed supported parts 312 do not necessarily have to be arranged parallel to each other.

下形板３１には、所定の位置にアンカーボルト３２用の穴（不図示）が形成される。このボルト穴は、ベースプレート４に形成されたボルト穴に対応する位置に形成される。下形板３１は架台２の上面に対して、例えば、溶接によって接合される。 Holes (not shown) for anchor bolts 32 are formed at predetermined positions in the lower plate 31. These bolt holes are formed at positions corresponding to the bolt holes formed in the base plate 4. The lower plate 31 is joined to the upper surface of the frame 2 by, for example, welding.

アンカーボルト３２は、下形板３１に形成されたアンカーボルト３２用の穴に挿入されて固定される。アンカーボルト３２は、２つのナット３３が下形板３１を挟んだ状態で締結されることによって、下形板３１に固定される。 The anchor bolt 32 is inserted into a hole for the anchor bolt 32 formed in the lower plate 31 and fixed in place. The anchor bolt 32 is fixed to the lower plate 31 by fastening two nuts 33 with the lower plate 31 in between.

アンカーボルト３２の上部に対して、ベースプレート４のボルト用の穴が挿通される。
そして、アンカーボルト３２にナット３４を締め付けることによりベースプレート４が基礎コンクリートに固定される。 The upper part of the anchor bolt 32 is inserted into the bolt hole of the base plate 4 .
Then, the base plate 4 is fixed to the foundation concrete by tightening the nuts 34 onto the anchor bolts 32.

［柱脚アンカー構造体の設置工程］
次に、図２～図５を用いて柱脚アンカー構造体１の設置工程について説明する。 [Installation process of column base anchor structure]
Next, the installation process of the column base anchor structure 1 will be described with reference to FIGS.

図２～図５は、柱脚アンカー構造体１の設置工程を説明する図である。
まず、均しコンクリート５上の適切な位置に架台２が載置される（図２参照）。次に、架台２上に組み立てられたアンカーフレーム３が載置され、架台２とアンカーフレーム３の下形板３１とが溶接により接合される。 2 to 5 are diagrams illustrating the installation process of the column base anchor structure 1.
First, the base 2 is placed at an appropriate position on the leveled concrete 5 (see FIG. 2). Next, the assembled anchor frame 3 is placed on the base 2, and the base 2 and the lower plate 31 of the anchor frame 3 are joined by welding.

アンカーボルト３２の上端付近には、各アンカーボルト３２の姿勢を垂直状態に維持し、各アンカーボルト３２間のピッチを維持するための上形板３５がナット３４によって固定されている。上形板３５の形状は、下形板３１の形状と同じであってもよい。下形板３１と同様に上形板３５も複数の長方形の鉄板を溶接などにより枠状に接合して形成してもよい。上形板３５を用いてアンカーボルト３２を仮留めしているため、基礎コンクリート６を流し込む際にアンカーボルト３２にコンクリートから力が加わったとしても、アンカーボルト３２の位置がずれることはない。 An upper form plate 35 is fixed by a nut 34 near the upper end of the anchor bolts 32 to maintain the posture of each anchor bolt 32 in a vertical state and to maintain the pitch between each anchor bolt 32. The shape of the upper form plate 35 may be the same as that of the lower form plate 31. Like the lower form plate 31, the upper form plate 35 may be formed by joining multiple rectangular iron plates into a frame shape by welding or the like. Since the anchor bolts 32 are temporarily fixed using the upper form plate 35, the position of the anchor bolts 32 will not shift even if force is applied to the anchor bolts 32 from the concrete when the foundation concrete 6 is poured.

つづいて、建物の基礎となる基礎コンクリート６が打設される（図３参照）。基礎コンクリート６は、上形板３５の下面付近まで打設される。基礎コンクリート６が打設されると、架台２、およびアンカーフレーム３の大部分は、基礎コンクリート６に埋設される。 Next, the foundation concrete 6 that will form the foundation of the building is poured (see Figure 3). The foundation concrete 6 is poured up to near the bottom surface of the upper plate 35. Once the foundation concrete 6 is poured, the frame 2 and most of the anchor frame 3 are embedded in the foundation concrete 6.

基礎コンクリート６が固まると、上形板３５が取り外される（図４参照）。 Once the foundation concrete 6 has hardened, the upper plate 35 is removed (see Figure 4).

その後、基礎コンクリート６から露出したアンカーボルト３２にベースプレート４に形成されたボルト用の穴を挿通させて、ベースプレート４を基礎コンクリート６上に設置する（図５参照）。つづいて、ナット３４がアンカーボルト３２に締め付けられ、ベースプレート４が基礎コンクリート６上に固定される。 Then, the anchor bolts 32 exposed from the concrete foundation 6 are inserted into the bolt holes formed in the base plate 4, and the base plate 4 is installed on the concrete foundation 6 (see FIG. 5). Next, the nuts 34 are tightened onto the anchor bolts 32, and the base plate 4 is fixed onto the concrete foundation 6.

このような工程により、柱脚アンカー構造体１が基礎コンクリート６に設置されるとともに、柱脚アンカー構造体１によりベースプレート４が基礎コンクリート６に固定される。なお、ベースプレート４と基礎コンクリート６との間には、モルタルが注入されてもよい。 By this process, the column base anchor structure 1 is installed in the foundation concrete 6, and the column base anchor structure 1 fixes the base plate 4 to the foundation concrete 6. Mortar may be injected between the base plate 4 and the foundation concrete 6.

［柱脚アンカー構造体の仕様］
次に、柱脚アンカー構造体１の仕様について説明する。 [Specifications for column base anchor structure]
Next, the specifications of the column base anchor structure 1 will be described.

柱脚アンカー構造体１を構成する架台２および下形板３１の仕様は、規格によってあらかじめ定められている。ここで、架台２および下形板３１の仕様とは、架台２および下形板３１の各部の寸法を定めるものである。規格には、各部の寸法が定められた架台２および下形板３１に係る複数の仕様が含まれる。柱に接合されるベースプレート４が決まると、ベースプレート４に適合する下形板３１および架台２が規格で定められた複数の仕様の中から選択される。 The specifications of the mount 2 and the lower plate 31 that constitute the column base anchor structure 1 are determined in advance by standards. Here, the specifications of the mount 2 and the lower plate 31 stipulate the dimensions of each part of the mount 2 and the lower plate 31. The standard includes multiple specifications for the mount 2 and the lower plate 31, in which the dimensions of each part are determined. Once the base plate 4 to be joined to the column is determined, the lower plate 31 and mount 2 that are compatible with the base plate 4 are selected from multiple specifications determined by the standard.

図６は、柱脚アンカー構造体１の下形板３１の規格の一例であって、仕様の一部（３１Ａ、３１Ｂ、３１Ｃ）を示したものである。 Figure 6 shows an example of the standard for the lower plate 31 of the column base anchor structure 1, showing some of the specifications (31A, 31B, 31C).

下形板３１は、規格によって、５００×５００用下形板３１Ａ、５５０×５５０用下形板３１Ｂ、および６００×６００用下形板３１Ｃなどがあらかじめ段階的に定められている。 The lower form plate 31 is specified in stages according to the standard, such as a lower form plate 31A for 500 x 500, a lower form plate 31B for 550 x 550, and a lower form plate 31C for 600 x 600.

５００×５００用下形板３１Ａは、外形寸法ａが７８０［ｍｍ］、開口の一辺の長さ、つまり、対向する一対の被支持部の内側端の間隔ｂが５００［ｍｍ］である。５５０×５５０用下形板３１Ｂは、外形寸法ａが８３０［ｍｍ］、開口の一辺の長さｂが５５０［ｍｍ］である。６００×６００用下形板３１Ｃは、外形寸法ａが８８０［ｍｍ］、開口の一辺の長さｂが６００［ｍｍ］である。 The lower plate 31A for 500 x 500 has an outer dimension a of 780 mm, and the length of one side of the opening, i.e., the distance b between the inner ends of a pair of opposing supported parts, is 500 mm. The lower plate 31B for 550 x 550 has an outer dimension a of 830 mm, and the length of one side of the opening b is 550 mm. The lower plate 31C for 600 x 600 has an outer dimension a of 880 mm, and the length of one side of the opening b is 600 mm.

すなわち、この規格では、各下形板３１の開口の一辺の長さｂが、５０［ｍｍ］ごとに大きくなるように定められている。換言すれば、開口３１１を挟んで対向して設けられた一対の被支持部３１２の内側端の間隔ｂが段階的に大きくなるように規格で定められている。 In other words, this standard stipulates that the length b of one side of the opening of each lower plate 31 increases in increments of 50 mm. In other words, the standard stipulates that the distance b between the inner ends of a pair of supported parts 312 that are arranged opposite each other across the opening 311 increases in stages.

図７は、柱脚アンカー構造体１の架台２の規格の一例であって、仕様の一部（２Ａ、２Ｂ、３Ｃ）を示したものである。 Figure 7 shows an example of the standards for the base 2 of the column base anchor structure 1, showing some of the specifications (2A, 2B, 3C).

架台２は、規格によって、５００×５００用架台２Ａ、５５０×５５０用架台２Ｂ、および６００×６００用架台２Ｃなどがあらかじめ段階的に定められている。 The mounts 2 are specified in stages according to the standard, such as mount 2A for 500 x 500, mount 2B for 550 x 550, and mount 2C for 600 x 600.

５００×５００用架台２Ａは、一対の支持部２２１の外側端の間隔ｃが５４０［ｍｍ］、内側端の間隔ｄが４００［ｍｍ］、支持部２２１の幅ｅが７０［ｍｍ］、凸部２２２の外側端の間隔ｆが４９０［ｍｍ］、凸部２２２の幅ｇが４５［ｍｍ］である。５５０×５５０用架台２Ｂは、一対の支持部２２１の外側端の間隔ｃが５９０［ｍｍ］、内側端の間隔ｄが４５０［ｍｍ］、支持部２２１の幅ｅが７０［ｍｍ］、凸部２２２の外側端の間隔ｆが５４０［ｍｍ］、凸部２２２の幅ｇが４５［ｍｍ］である。６００×６００用架台２Ｃは、一対の支持部２２１の外側端の間隔ｃが６４０［ｍｍ］、内側端の間隔ｄが５００［ｍｍ］、支持部２２１の幅が７０［ｍｍ］、凸部２２２の外側端の間隔ｆが５９０［ｍｍ］、凸部２２２の幅ｇが４５［ｍｍ］である。 The 500x500 stand 2A has a pair of supports 221 with a spacing c of 540 mm between the outer ends, a spacing d of 400 mm between the inner ends, a width e of 70 mm between the supports 221, a spacing f of 490 mm between the outer ends of the protrusions 222, and a width g of 45 mm between the protrusions 222. The 550x550 stand 2B has a pair of supports 221 with a spacing c of 590 mm between the outer ends, a spacing d of 450 mm between the inner ends, a width e of 70 mm between the supports 221, a spacing f of 540 mm between the outer ends of the protrusions 222, and a width g of 45 mm between the protrusions 222. The 600 x 600 stand 2C has a pair of support parts 221 with a spacing c of 640 mm between the outer ends, a spacing d of 500 mm between the inner ends, a width of 70 mm for the support parts 221, a spacing f of 590 mm between the outer ends of the protrusions 222, and a width g of 45 mm for the protrusions 222.

次に、所定の仕様の架台２（２Ｂ）上に、対応する適切な仕様の下形板３１（３１Ｂ）が配置された場合と、一段階小さい仕様の下形板３１（３１Ａ）が配置された場合と、一段階大きい仕様の下形板３１（３１Ｃ）が配置された場合について、順に説明する。 Next, we will explain the cases where a lower plate 31 (31B) with appropriate specifications is placed on a stand 2 (2B) with specified specifications, where a lower plate 31 (31A) with a lower specification that is one step smaller is placed, and where a lower plate 31 (31C) with a lower specification that is one step larger is placed.

図８は、５５０×５５０用架台２Ｂに５５０×５５０用下形板３１Ｂが配置された状態の柱脚アンカー構造体１の平面図であり、図９は、図８のＡ－Ａ線矢視図である。 Figure 8 is a plan view of the column base anchor structure 1 with the 550 x 550 lower plate 31B placed on the 550 x 550 mounting stand 2B, and Figure 9 is a view taken along line A-A in Figure 8.

５５０×５５０用下形板３１Ｂの一対の被支持部３１２の内側端の間隔ｂは５５０［ｍｍ］であり、凸部２２２の外側端の間隔ｆは５４０［ｍｍ］である。したがって、各凸部２２２の外側端と５５０×５５０用下形板３１Ｂの開口３１１の内側面との隙間が５［ｍｍ］となる。つまり、建設現場の作業者は、凸部２２２の外側端が下形板３１の開口３１１の内側面にちょうど収まることを確認することによって、架台２Ｂに対して適切な下形板３１Ｂが載置されていることを確認することができる。また、支持部２２１の上面に、架台２Ｂと下形板３１Ｂとを接合するための溶接代が確保され、架台２と下形板３１Ｂとを溶接部２２３を介して接合することができる。なお、各支持部２２１は、２０［ｍｍ］の幅で下形板３１Ｂの被支持部３１２を支持することとなる。 The distance b between the inner ends of the pair of supported parts 312 of the lower plate 31B for 550 x 550 is 550 [mm], and the distance f between the outer ends of the convex parts 222 is 540 [mm]. Therefore, the gap between the outer end of each convex part 222 and the inner surface of the opening 311 of the lower plate 31B for 550 x 550 is 5 [mm]. In other words, a worker at the construction site can confirm that the appropriate lower plate 31B is placed on the frame 2B by confirming that the outer end of the convex part 222 fits exactly into the inner surface of the opening 311 of the lower plate 31. In addition, a welding allowance for joining the frame 2B and the lower plate 31B is secured on the upper surface of the support part 221, and the frame 2 and the lower plate 31B can be joined via the weld part 223. Each support part 221 supports the supported part 312 of the lower plate 31B with a width of 20 [mm].

図１０は、５５０×５５０用架台２Ｂに５００×５００用下形板３１Ａが配置された状態の柱脚アンカー構造体１の平面図であり、図１１は、図１０のＢ－Ｂ線矢視図である。 Figure 10 is a plan view of the column base anchor structure 1 with the 500 x 500 lower plate 31A placed on the 550 x 550 stand 2B, and Figure 11 is a view taken along line B-B in Figure 10.

５００×５００用下形板３１Ａの一対の被支持部３１２の内側端の間隔ｂは５００［ｍｍ］であり、凸部２２２の外側端の間隔ｆは５４０［ｍｍ］である。つまり、５００×５００用下形板３１Ａが凸部２２２の上に載置され、不安定な状態となる。また、凸部２２２によって支持部２２１と被支持部３１２との間に隙間ができる。したがって、建設現場の作業者は、架台２Ｂに対して適切な下形板が載置されていないことに気付くことができる。特に、支持部２２１の幅が大きくなってしまうような場合において、段階が低い小さい間隔の仕様の下形板も架台２に載せることが可能となってしまうが、支持部２２１に凸部２２２を設けることで、これを防止することができるので効果的である。 The distance b between the inner ends of the pair of supported parts 312 of the 500x500 lower plate 31A is 500 [mm], and the distance f between the outer ends of the convex parts 222 is 540 [mm]. In other words, the 500x500 lower plate 31A is placed on the convex parts 222, resulting in an unstable state. In addition, the convex parts 222 create a gap between the supporting parts 221 and the supported parts 312. Therefore, workers at the construction site can notice that an appropriate lower plate is not placed on the frame 2B. In particular, when the width of the supporting parts 221 becomes large, a lower plate with a small gap specification at a low step can also be placed on the frame 2, but by providing the convex parts 222 on the supporting parts 221, this can be prevented effectively.

図１２は、５５０×５５０用架台２Ｂに６００×６００用下形板３１Ｃが配置される状態の柱脚アンカー構造体１の平面図であり、図１３は、図１２のＣ－Ｃ線矢視図である。
５５０×５５０用架台２Ｂの一対の支持部２２１の外側端の間隔ｃは５９０［ｍｍ］であり、６００×６００用下形板３１Ｃの一対の被支持部３１２の内側端の間隔ｂは６００［ｍｍ］である。つまり、一対の被支持部３１２の内側端の間隔ｂは、架台２Ｂの支持部２２１の外側端の間隔ｃよりも長い。そのため、下形板３１Ｃを架台２Ｂの支持部２２１に載置することができない。したがって、建設現場の作業者は、下形板３１Ｃが架台２Ｂに適合するものではないことに気付くことができる。 12 is a plan view of the column base anchor structure 1 in a state in which a 600×600 lower plate 31C is placed on a 550×550 rack 2B, and FIG. 13 is a view seen from the arrows CC in FIG.
The distance c between the outer ends of the pair of support parts 221 of the 550x550 stand 2B is 590 [mm], and the distance b between the inner ends of the pair of supported parts 312 of the 600x600 lower plate 31C is 600 [mm]. In other words, the distance b between the inner ends of the pair of supported parts 312 is longer than the distance c between the outer ends of the support parts 221 of the stand 2B. Therefore, the lower plate 31C cannot be placed on the support parts 221 of the stand 2B. Therefore, the workers at the construction site can notice that the lower plate 31C is not suitable for the stand 2B.

なお、上記説明と同様に、５００×５００用架台２Ａと５００×５００用下形板３１Ａとが組み合わされる場合は、架台２Ａ上に下形板３１Ａを載置することができるとともに、凸部２２２の外側端が５００×５００用下形板３１Ａの開口３１１の内側面にちょうど収まる。したがって、建設現場の作業者は、架台２Ａに対して適切な下形板３１Ａが載置されていることを確認することができる。また、支持部２２１の上面には架台２Ａと下形板３１Ａとを接合するための溶接代が確保される。 As explained above, when the 500 x 500 stand 2A and the 500 x 500 lower plate 31A are combined, the lower plate 31A can be placed on the stand 2A, and the outer end of the protrusion 222 fits exactly on the inner surface of the opening 311 of the 500 x 500 lower plate 31A. Therefore, workers at the construction site can confirm that the appropriate lower plate 31A is placed on the stand 2A. In addition, a welding allowance is secured on the upper surface of the support portion 221 to join the stand 2A and the lower plate 31A.

一方、５００×５００用架台２Ａと５５０×５５０用下形板３１Ｂとが組み合わされる場合は、一対の支持部２２１の外側端の間隔ｃよりも被支持部３１２の内側端の間隔ｂの方が長くなる。そのため、架台２Ａ上に下形板３１Ｂを載置することができない。したがって、建設現場の作業者は、下形板３１Ｂが架台２Ａに適合するものではないことに気付くことができる。 On the other hand, when the 500 x 500 stand 2A is combined with the 550 x 550 lower plate 31B, the distance b between the inner ends of the supported parts 312 is longer than the distance c between the outer ends of the pair of supporting parts 221. Therefore, the lower plate 31B cannot be placed on the stand 2A. Therefore, workers at the construction site can notice that the lower plate 31B does not fit the stand 2A.

また、６００×６００用架台２Ｃと６００×６００用下形板３１Ｃとが組み合わされる場合は、架台２Ｃ上に下形板３１Ｃを載置することができるとともに、凸部２２２の外側端が６００×６００用下形板３１Ｃの開口３１１の内側面にちょうど収まる。したがって、建設現場の作業者は、架台２Ｃに対して適切な下形板３１Ｃが載置されていることを確認することができる。また、支持部２２１の上面には架台２Ｃと下形板３１Ｃとを接合するための溶接代が確保される。 When the 600 x 600 stand 2C and the 600 x 600 lower plate 31C are combined, the lower plate 31C can be placed on the stand 2C, and the outer end of the protrusion 222 fits exactly on the inner surface of the opening 311 of the 600 x 600 lower plate 31C. Therefore, workers at the construction site can confirm that the appropriate lower plate 31C is placed on the stand 2C. Also, a welding allowance is secured on the upper surface of the support 221 to join the stand 2C and the lower plate 31C.

一方、６００×６００用架台２Ｃと５５０×５５０用下形板３１Ｂとが組み合わされる場合は、５５０×５５０用下形板３１Ｂが凸部２２２の上に載置され、不安定な状態となる。また、凸部２２２によって支持部２２１と被支持部３１２との間に隙間ができる。したがって、建設現場の作業者は、下形板３１Ｂが架台２Ｃに適合するものではないことに気付くことができる。 On the other hand, when the 600 x 600 stand 2C and the 550 x 550 lower plate 31B are combined, the 550 x 550 lower plate 31B is placed on the convex portion 222, resulting in an unstable state. In addition, the convex portion 222 creates a gap between the supporting portion 221 and the supported portion 312. Therefore, workers at the construction site can notice that the lower plate 31B is not compatible with the stand 2C.

以上説明したように、本発明の第１の実施形態では、ベースプレート４の仕様に応じて適切なアンカーフレーム３および架台２が選択できるように、あらかじめアンカーフレーム３および架台２の仕様が規格で定められている。また、この規格では、仕様の異なる架台２とアンカーフレーム３とが適合しないようにあらかじめ各寸法が定められている。 As described above, in the first embodiment of the present invention, the specifications of the anchor frame 3 and the mount 2 are predefined by standard so that an appropriate anchor frame 3 and mount 2 can be selected according to the specifications of the base plate 4. In addition, in this standard, each dimension is predefined so that mounts 2 and anchor frames 3 with different specifications are not compatible.

特に、架台２の支持部２２１の幅ｅがある程度大きい場合、従来、架台２に仕様上適合しない下形板３１が載置され、架台２と下形板３１とが溶接されてしまうおそれがあった。しかし、本実施形態では、支持部２２１上に凸部２２２が設けられている。したがって、互いに異なる仕様の架台２およびアンカーフレーム３が誤って組み立てられることを防止することができる。 In particular, when the width e of the support portion 221 of the frame 2 is relatively large, conventionally, there was a risk that a lower plate 31 that does not match the specifications of the frame 2 would be placed on it, and the frame 2 and the lower plate 31 would be welded together. However, in this embodiment, a protrusion 222 is provided on the support portion 221. Therefore, it is possible to prevent the frame 2 and the anchor frame 3 of different specifications from being assembled erroneously.

本実施形態では、下形板３１の形状について、対向する一対の被支持部を二組設けて開口３１１を有する枠状にしたが、対向する一対の被支持部を一組だけ設けて構成するものであっても良い。この場合は対向する一対の被支持部を一組だけでそれに直交する一対の被支持部は設けられないので開口は存在しない。また、これに対応させて架台の横部材も同様に構成しても良い。 In this embodiment, the shape of the lower plate 31 is a frame having two pairs of opposing supported parts and an opening 311, but it may be configured with only one pair of opposing supported parts. In this case, there is only one pair of opposing supported parts and no pair of supported parts perpendicular to it, so there is no opening. The horizontal members of the frame may also be configured in a similar manner to correspond to this.

［第２の実施形態］
次に、本発明の第２の実施形態の柱脚アンカー構造体１について説明する。第２の実施形態の柱脚アンカー構造体１は、架台の構成が第１の実施形態とは異なる。下形板及び架台の規格については、図６及び図７に示す第１の実施形態のものと同様である。 Second Embodiment
Next, a column base anchor structure 1 according to a second embodiment of the present invention will be described. The column base anchor structure 1 according to the second embodiment differs from the first embodiment in the configuration of the mount. The specifications of the lower form plate and the mount are the same as those of the first embodiment shown in Figs. 6 and 7.

図１４は、第２の実施形態の柱脚アンカー構造体１の架台７を示す図である。架台７は、支柱７１、横部材７２、および治具７３を有する。 Figure 14 shows the base 7 of the column base anchor structure 1 of the second embodiment. The base 7 has a support 71, a cross member 72, and a jig 73.

支柱７１は、均しコンクリート５（図２参照）に対して垂直に配置される部材である。支柱７１には、材軸方向に長い山形鋼などの鋼材が用いられる。 The pillars 71 are members that are placed perpendicular to the leveling concrete 5 (see Figure 2). The pillars 71 are made of steel materials such as angle iron that are long in the axial direction.

横部材７２は、上面に下形板３１が載置される部材である。横部材７２には、材軸方向に長い山形鋼などの鋼材が用いられる。また、横部材７２は、両端が治具７３に接合されて、治具７３によって支持される。また、横部材７２は、支持部７２１を有している。 The horizontal member 72 is a member on which the lower plate 31 is placed. The horizontal member 72 is made of steel material such as an angle iron that is long in the axial direction. In addition, both ends of the horizontal member 72 are joined to a jig 73 and are supported by the jig 73. The horizontal member 72 also has a support portion 721.

支持部７２１は、互いに平行に配置された一対の横部材７２の上端から水平方向かつ互いに離間する方向に突出する部分である。この一対の支持部７２１の上面は下形板３１の下面に当接し、アンカーフレーム３を支持する。 The support parts 721 are parts that protrude horizontally and away from each other from the upper ends of a pair of cross members 72 arranged parallel to each other. The upper surfaces of the pair of support parts 721 abut against the lower surface of the lower plate 31 and support the anchor frame 3.

治具７３は、支柱７１の上端部に接合され、横部材７２を支持する部材である。治具７３は、帯状の板部材が階段状に折り曲げられて形成される。 The jig 73 is a member that is joined to the upper end of the support 71 and supports the cross member 72. The jig 73 is formed by bending a strip-shaped plate member into a stepped shape.

図１５は、治具７３の構造を示す斜視図である。治具７３は、山形部７３１、突出部７３２、横部材支持部７３３、およびリップ７３４を有している。 Figure 15 is a perspective view showing the structure of the jig 73. The jig 73 has a mountain-shaped portion 731, a protruding portion 732, a cross member support portion 733, and a lip 734.

山形部７３１は、治具７３の中央部分に位置しており、山形に形成される部分である。山形部７３１の外側面は、支柱７１の内側面に接合される。 The mountain-shaped portion 731 is located in the center of the jig 73 and is formed into a mountain shape. The outer surface of the mountain-shaped portion 731 is joined to the inner surface of the support 71.

突出部７３２は、その一端が山形部７３１の端部から延出する部分であり、山形部７３１から外側に向けて９０°の角度で折り曲げられて形成される。この突出部７３２は、横部材７２を支柱７１よりも外側に配置するために設けられる。つまり、突出部７３２の長さを変えることにより横部材７２に対する支柱７１の相対位置を変更することができる。 The protrusion 732 is a portion whose one end extends from the end of the angled portion 731, and is formed by bending the angled portion 731 outward at a 90° angle. This protrusion 732 is provided to position the cross member 72 outward from the support 71. In other words, by changing the length of the protrusion 732, the relative position of the support 71 to the cross member 72 can be changed.

横部材支持部７３３は、突出部７３２の他端から延出する部分であり、突出部７３２から横部材７２の長手方向に向けて折り曲げられて形成される。横部材支持部７３３は、横部材７２の端部に接続される。 The horizontal member support part 733 is a part that extends from the other end of the protruding part 732, and is formed by bending the protruding part 732 in the longitudinal direction of the horizontal member 72. The horizontal member support part 733 is connected to the end part of the horizontal member 72.

リップ７３４は、横部材支持部７３３の端部付近において上方に延びる部分が水平方向に折り曲げられて形成される。リップ７３４は、横部材支持部７３３の端部付近から所定の長さだけ外側に向けて突出し、支持部７２１の上面に延在する。つまり、リップ７３４は、本発明における凸部に相当する。リップ７３４の突出長さを対応する下形板３１の一対の被支持部３１２の内側端の間隔ｂに合わせて設計することにより、一対のリップ（凸部）７３４の外側端が下形板３１の開口３１１の内側面にちょうど収まるようにすることができる。結果として、下形板３１と架台７とが対応する仕様のものであるか否かを建設現場において確認することができる。 The lip 734 is formed by bending the portion extending upward near the end of the horizontal member support portion 733 horizontally. The lip 734 protrudes outward a predetermined length from near the end of the horizontal member support portion 733 and extends onto the upper surface of the support portion 721. In other words, the lip 734 corresponds to the convex portion in the present invention. By designing the protruding length of the lip 734 to match the distance b between the inner ends of the pair of supported portions 312 of the corresponding lower form plate 31, the outer ends of the pair of lips (convex portions) 734 can be made to fit exactly into the inner surface of the opening 311 of the lower form plate 31. As a result, it is possible to check at the construction site whether the lower form plate 31 and the frame 7 are of compatible specifications.

図１６は、架台７上に適切な仕様の下形板３１が載置された状態（５５０×５５０用架台に５５０×５５０用下形板が配置された状態）を示している。この柱脚アンカー構造体１では、リップ７３４の外側端が開口３１１の内側面にちょうど収まっている。つまり、建設現場では、リップ７３４の外側端が下形板３１の開口３１１の内側面に収まっているか否かを確認することによって、下形板３１と架台７とが対応する仕様のものであるか確認することができる。 Figure 16 shows a state where a lower form plate 31 of appropriate specifications is placed on the mounting base 7 (a state where a 550 x 550 lower form plate is placed on a 550 x 550 mounting base). In this column base anchor structure 1, the outer end of the lip 734 fits exactly on the inner surface of the opening 311. In other words, at the construction site, by checking whether the outer end of the lip 734 fits on the inner surface of the opening 311 of the lower form plate 31, it can be confirmed whether the lower form plate 31 and mounting base 7 are of compatible specifications.

図１７は、架台７に対して段階が低い小さい間隔の仕様の下形板３１が載置された状態（５５０×５５０用架台に５００×５００用下形板が配置された状態）を示している。この柱脚アンカー構造体１では、リップ７３４と下形板３１とが重なっている。そのため、下形板３１が不安定な状態で架台７上に載置されている。また、リップ７３４によって支持部７２１と被支持部３１２との間に隙間ができる。これにより、建設現場では、架台７に対して段階が低い小さい間隔の仕様の下形板３１が載置されていることに気づくことができる。 Figure 17 shows the state where the lower plate 31 with a small gap specification that is a low step is placed on the stand 7 (the state where the lower plate for 500 x 500 is placed on the stand for 550 x 550). In this column base anchor structure 1, the lip 734 and the lower plate 31 overlap. Therefore, the lower plate 31 is placed on the stand 7 in an unstable state. In addition, the lip 734 creates a gap between the supporting portion 721 and the supported portion 312. This allows the construction site to notice that the lower plate 31 with a small gap specification that is a low step is placed on the stand 7.

図１８は、架台７に対して、段階が高い大きい間隔の仕様の下形板３１が載置されるときの状態（５５０×５５０用架台に６００×６００用下形板が配置された状態）を示している。この場合、架台７が下形板３１の開口３１１に嵌り込み、下形板３１が架台７に載置できない。これにより、建設現場では、架台７に対し段階が高い大きい間隔の仕様の下形板３１が載置されていることに気づくことができる。 Figure 18 shows the state when a lower form plate 31 with a high step and large spacing is placed on the stand 7 (a 600 x 600 lower form plate is placed on a 550 x 550 stand). In this case, the stand 7 gets stuck in the opening 311 of the lower form plate 31, and the lower form plate 31 cannot be placed on the stand 7. This allows the construction site to notice that a lower form plate 31 with a high step and large spacing has been placed on the stand 7.

なお、リップ７３４は治具７３を形成する板部材を折り曲げて形成されるものに限らず、例えば、図１９に示すように横部材支持部７３３に溶接などにより接合されてもよい。 The lip 734 is not limited to being formed by bending the plate member that forms the jig 73, but may be joined to the cross member support portion 733 by welding, for example, as shown in FIG. 19.
