Description

本発明は、コンクリート基礎を打設する際に、そのコンクリート基礎に凹陥部、例えば、建物、工作物等を固定するアンカーボルトを埋め込んだり、支柱を建柱するためのアンカーホール、排水用溝、排水用集水ピットなどを形成する凹陥部形成用治具に関する。   In the present invention, when placing a concrete foundation, a recessed portion, for example, an anchor bolt for fixing a building, a workpiece, or the like is embedded in the concrete foundation, an anchor hole for laying a pillar, a drainage groove, The present invention relates to a recess forming jig for forming a drainage water collecting pit.

建物、工作物を建造するには、まずコンクリート基礎を打設する。このコンクリート基礎を打設する際に、治具を用いてアンカーホールを形成する。
このアンカーホールにアンカーボルトを埋め込み、そのアンカーボルトを利用して建物、工作物を固定するのが一般的である。 In order to build buildings and structures, a concrete foundation is first placed. When placing the concrete foundation, an anchor hole is formed using a jig.
Generally, anchor bolts are embedded in the anchor holes, and buildings and workpieces are fixed using the anchor bolts.

前述の治具としては特許文献１に開示されたように、固定部材とセパレータと筒状体を備え、その固定部材をコンクリート基礎の底部寄りに固定し、この固定部材にセパレータの下部を連結すると共に、そのセパレータの上部に筒状体を高さ調整自在に連結するようにした治具が知られている。
この治具をコンクリートを打設する前にコンクリート基礎の底部に設け、その筒状体の高さを調整して筒状体の上面をコンクリート基礎の上面と同一高さとし、その後にコンクリートを打設することで筒状体によって凹陥部、例えばアンカーホールを形成できる。 As disclosed in Patent Document 1, the above-described jig includes a fixing member, a separator, and a cylindrical body, and the fixing member is fixed near the bottom of the concrete foundation, and the lower part of the separator is connected to the fixing member. In addition, a jig is known in which a cylindrical body is connected to the upper portion of the separator so that the height can be adjusted.
This jig is installed at the bottom of the concrete foundation before placing the concrete, the height of the cylindrical body is adjusted so that the top surface of the tubular body is the same height as the top surface of the concrete foundation, and then the concrete is placed By doing so, a recessed portion, for example, an anchor hole can be formed by the cylindrical body.

特開２００５−２４８４５６号公報JP 2005-248456 A

前述した従来の治具は、筒状体の底板に穴を形成すると共に、その穴の周縁にナットを溶接して固着することで底板にねじ孔を形成し、このナット（ねじ孔）にセパレータの上ねじ部を螺合すると共に、ロック用のナットを締め付けてセパレータの上部に筒状体を連結し、前記ロック用のナットを弛めてセパレータと筒状体を相対的に回転することで筒状体の高さを調整できるようにしてある。
しかし、筒状体の底面にナットを溶接する作業が面倒で、底板にねじ孔を形成することが面倒である。しかも、溶接によって筒状体の底板に歪みが生じてナットが筒状体の底板に対して直角にならないことがある。
前述のように、ナットが筒状体の底板に対して直角でないと、そのナットとセパレータの上ねじ部を螺合して筒状体をセパレータに取付けた状態で、その筒状体とセパレータが真直ぐにならずに筒状体が斜めとなる。
このように、筒状体が斜めになると筒状体の上面が水平にならずに傾斜してしまうので、アンカーホールを正しく形成できない。 In the conventional jig described above, a hole is formed in the bottom plate of the cylindrical body, and a screw hole is formed in the bottom plate by welding and fixing a nut around the hole, and a separator is formed in the nut (screw hole). The upper threaded part is screwed together, the nut for locking is tightened to connect the cylindrical body to the upper part of the separator, the locking nut is loosened, and the separator and the cylindrical body are rotated relatively. The height of the cylindrical body can be adjusted.
However, the operation of welding the nut to the bottom surface of the cylindrical body is troublesome, and it is troublesome to form screw holes in the bottom plate. Moreover, the bottom plate of the cylindrical body may be distorted by welding, and the nut may not be perpendicular to the bottom plate of the cylindrical body.
As described above, if the nut is not perpendicular to the bottom plate of the cylindrical body, the cylindrical body and the separator are in a state in which the nut and the upper screw portion of the separator are screwed together and the cylindrical body is attached to the separator. The cylindrical body is slanted without being straight.
Thus, when the cylindrical body is inclined, the upper surface of the cylindrical body is inclined without being horizontal, and thus the anchor hole cannot be formed correctly.

本発明の目的は、筒状体の底板に簡単にねじ孔を形成できると共に、筒状体とセパレータを真直ぐに直結できるようにした凹陥部形成用治具を提供することである。   An object of the present invention is to provide a jig for forming a recess, which can easily form a screw hole in a bottom plate of a cylindrical body, and can directly connect the cylindrical body and a separator.

本発明者等は、前述した従来の課題を解決すべく鋭意研究実験した結果、ナットを筒状体の底板にボルト・ナットを用いて固着すれば底板に歪みなどが発生しないのでナットを筒状体の底板に真直ぐに取付けできることを見出した。
しかし、ナットを底板にボルト・ナットで固着するには大変面倒な加工が必要となり、実用的ではなかった。
そこで、本発明者等はさらに研究、実験した結果、ナットに相当するねじ孔を有する軸体の外周面にねじ部を形成したねじ軸を見出し、このねじ軸を底板の孔に挿通し、そのねじ軸の外周面のねじ部に上ナットと下ナットを螺合して底板の上下面に押しつけることでねじ軸を底板に固着できることを見出し、本発明に到った。
前述のねじ孔を有する軸体の外周面にねじ部を形成したねじ軸は、本発明の治具のみではなく、他のものにも応用することができる。 As a result of diligent research and experiments to solve the above-described conventional problems, the present inventors have found that if the nut is fixed to the bottom plate of the cylindrical body using bolts and nuts, the bottom plate will not be distorted, so the nut is cylindrical. It was found that it can be attached straight to the bottom plate of the body.
However, fixing the nut to the bottom plate with bolts and nuts required very troublesome processing and was not practical.
Therefore, as a result of further research and experiments, the present inventors have found a screw shaft in which a screw portion is formed on the outer peripheral surface of a shaft body having a screw hole corresponding to a nut, and this screw shaft is inserted into a hole in a bottom plate. The present inventors have found that the screw shaft can be fixed to the bottom plate by screwing the upper nut and the lower nut onto the threaded portion of the outer peripheral surface of the screw shaft and pressing the nut against the upper and lower surfaces of the bottom plate.
The screw shaft in which the thread portion is formed on the outer peripheral surface of the shaft body having the screw hole described above can be applied not only to the jig of the present invention but also to other types.

本発明は、コンクリート基礎４の底部４ａ又は鉄筋７に固着される固定部材３と、
この固定部材３に固着されるセパレータ２と、
このセパレータ２の上部に高さ調整自在に連結され、コンクリート基礎４に凹陥部６を形成するための筒状体１を備え、
前記筒状体１の底板１１に形成した孔１４に、外周面にねじ部１３ａを有すると共に、軸心にねじ孔１３ｂを有するねじ軸１３を、当該ねじ軸１３と孔１４との間に環状の隙間を有して挿通し、このねじ軸１３のねじ部１３ａに上ナット１５と下ナット１６を螺合し、その上ナット１５を前記底板１１の上面１１ａに押しつけ、かつ下ナット１６を前記底板１１の下面１１ｂに押しつけることで前記ねじ軸１３を前記底板１１に固着し、
前記セパレータ２の上ねじ部２０に、前記ねじ軸１３のねじ孔１３ｂを螺合して当該セパレータ２の上部に筒状体１を連結したことを特徴とする凹陥部形成用治具である。 The present invention includes a fixing member 3 fixed to the bottom 4a or the reinforcing bar 7 of the concrete foundation 4,
A separator 2 fixed to the fixing member 3;
It is connected to the upper part of the separator 2 so as to be adjustable in height, and includes a cylindrical body 1 for forming a recessed portion 6 in the concrete foundation 4,
In the hole 14 formed in the bottom plate 11 of the cylindrical body 1, a screw shaft 13 having a screw portion 13 a on the outer peripheral surface and a screw hole 13 b on the axis is annular between the screw shaft 13 and the hole 14. The upper nut 15 and the lower nut 16 are screwed into the threaded portion 13a of the screw shaft 13, the upper nut 15 is pressed against the upper surface 11a of the bottom plate 11, and the lower nut 16 is The screw shaft 13 is fixed to the bottom plate 11 by being pressed against the lower surface 11b of the bottom plate 11,
The concave portion forming jig is characterized in that the threaded hole 13b of the screw shaft 13 is screwed into the upper threaded portion 20 of the separator 2 to connect the cylindrical body 1 to the upper portion of the separator 2.

本発明においては、セパレータ２の上ねじ部２０に上ロックナット２２を螺合し、この上ロックナット２２をねじ軸１３に締め付けることでねじ軸１３をロックすることができる。
このようにすれば、振動や衝撃などでねじ軸１３がセパレータ２の上ねじ部２０に対して弛むことがなく、この治具をコンクリート基礎４の底部４ａに設置した状態でコンクリートを流し込んだ際に筒状体１が動くことがなく所定の高さ位置にしっかりと保持できる。 In the present invention, the screw shaft 13 can be locked by screwing the upper lock nut 22 into the upper screw portion 20 of the separator 2 and tightening the upper lock nut 22 to the screw shaft 13.
In this way, the screw shaft 13 does not loosen with respect to the upper screw portion 20 of the separator 2 due to vibration or impact, and when the concrete is poured in a state where this jig is installed on the bottom portion 4a of the concrete foundation 4. The cylindrical body 1 can be firmly held at a predetermined height position without moving.

本発明によれば、筒状体１を回転することでねじ軸１３がセパレータ２の上ねじ部２０に対して回転して上下に移動するので、その筒状体１の高さを調整できる。
また、底板１１の孔１４にねじ軸１３を挿通し、上ナット１５と下ナット１６を螺合して締め付けることでねじ軸１３が底板１１に固着され、底板１１にねじ孔１３ｂを形成することができるので、その作業が簡単であるから、筒状体１の底板１１にねじ孔１３ｂを簡単に形成できる。
しかも、底板１１の上面１１ａに押しつけられた上ナット１５と底板１１の下面１１ｂに押しつけられた下ナット１６でねじ軸１３を底板１１に固着してあるから、そのねじ軸１３が底板１１に対して直角で、筒状体１とセパレータ２が真直ぐに連結される。 According to the present invention, by rotating the cylindrical body 1, the screw shaft 13 rotates relative to the upper screw portion 20 of the separator 2 and moves up and down, so that the height of the cylindrical body 1 can be adjusted.
Further, the screw shaft 13 is inserted into the hole 14 of the bottom plate 11, and the upper nut 15 and the lower nut 16 are screwed and tightened to fix the screw shaft 13 to the bottom plate 11, thereby forming the screw hole 13 b in the bottom plate 11. Since the operation is simple, the screw hole 13b can be easily formed in the bottom plate 11 of the cylindrical body 1.
Moreover, since the screw shaft 13 is fixed to the bottom plate 11 with the upper nut 15 pressed against the upper surface 11 a of the bottom plate 11 and the lower nut 16 pressed against the lower surface 11 b of the bottom plate 11, the screw shaft 13 is fixed to the bottom plate 11. At right angles, the cylindrical body 1 and the separator 2 are connected straight.

図１と図２に示すように、筒状体１とセパレータ２と固定部材３で凹陥部形成用治具としてある。
前記筒状体１は、筒１０と、この筒１０の下部に取付けた底板１１と、その筒１０の上部に取付けた上蓋１２で下面と上面が閉塞された筒形状で、その底板１１にセパレータ取付用のねじ軸１３が固着してある。
このねじ軸１３は、外周面にねじ部１３ａを有すると共に、軸心にねじ孔１３ｂを有している。このねじ孔１３ｂはねじ軸１３の軸方向両端面（上下面）に開口している。なお、ねじ孔１３ｂはねじ軸１３の下面にのみ開口しても良い。
前記セパレータ２はロッド形状で、その上部には上ねじ部２０、下部には下ねじ部２１を有している。この上ねじ部２０には上ロックナット２２が螺合してあると共に、下ねじ部２１には下ロックナット２３が螺合している。
前記固定部材３はねじ孔３０を有する本体３１と、この本体３１の下部に一体的に設けた複数の変形部３２を有する形状である。 As shown in FIGS. 1 and 2, a cylindrical body 1, a separator 2, and a fixing member 3 are used as a recess forming jig.
The cylindrical body 1 has a cylinder 10, a bottom plate 11 attached to the lower part of the cylinder 10, and a cylindrical shape whose upper and lower surfaces are closed by an upper lid 12 attached to the upper part of the cylinder 10. A screw shaft 13 for attachment is fixed.
The screw shaft 13 has a screw portion 13a on the outer peripheral surface and a screw hole 13b on the shaft center. The screw holes 13b are open at both axial end surfaces (upper and lower surfaces) of the screw shaft 13. The screw hole 13b may be opened only on the lower surface of the screw shaft 13.
The separator 2 is rod-shaped, and has an upper screw portion 20 at the upper portion and a lower screw portion 21 at the lower portion. An upper lock nut 22 is screwed to the upper screw portion 20, and a lower lock nut 23 is screwed to the lower screw portion 21.
The fixing member 3 has a shape having a main body 31 having a screw hole 30 and a plurality of deformation portions 32 integrally provided at a lower portion of the main body 31.

前記固定部材３は図１に仮想線で示すように、コンクリート基礎４の底部４ａ、例えば均しコンクリートに形成した穴５に固定される。
例えば、固定部材３の本体３１を穴５に入れてハンマー等で打撃することで変形部３２を変形して固定する。変形ではなく、接着剤などを用いて接着して固定しても良い。
前記セパレータ２の下部は固定部材３に取付けられる。
例えば、セパレータ２の下ねじ部２１を固定部材３のねじ孔３０に螺合し、下ロックナット２３を締め付けてロックすることで、セパレータ２の下部を固定部材３に取付ける。 As shown in phantom lines in FIG. 1, the fixing member 3 is fixed to a bottom 4a of a concrete foundation 4, for example, a hole 5 formed in leveled concrete.
For example, the deformable portion 32 is deformed and fixed by putting the main body 31 of the fixing member 3 into the hole 5 and hitting it with a hammer or the like. Instead of deformation, it may be bonded and fixed using an adhesive or the like.
The lower part of the separator 2 is attached to the fixing member 3.
For example, the lower part of the separator 2 is attached to the fixing member 3 by screwing the lower screw portion 21 of the separator 2 into the screw hole 30 of the fixing member 3 and tightening and locking the lower lock nut 23.

前記筒状体１とセパレータ２の上部は、そのセパレータ２の上ねじ部２０を筒状体１のねじ軸１３のねじ孔１３ｂに螺合し、上ロックナット２２を締め付けてロックすることで連結される。
このようであるから、固定部材３にセパレータ２の下部を取付けた状態で、上ロックナット２２を弛め、筒状体１とともにねじ軸１３を回転することで筒状体１がセパレータ２に対して上下方向に移動するので、その筒状体１の取付け高さを調整して所定の高さとすることができる。
例えば、筒１０の上端面１０ａをコンクリート基礎４の上面４ｂと同一高さとすることができる。 The upper part of the cylindrical body 1 and the separator 2 is connected by screwing the upper screw portion 20 of the separator 2 into the screw hole 13b of the screw shaft 13 of the cylindrical body 1, and tightening and locking the upper lock nut 22. Is done.
Thus, with the lower part of the separator 2 attached to the fixing member 3, the upper lock nut 22 is loosened and the screw body 13 is rotated together with the tubular body 1, so that the tubular body 1 is separated from the separator 2. Therefore, the mounting height of the cylindrical body 1 can be adjusted to a predetermined height.
For example, the upper end surface 10 a of the cylinder 10 can be made the same height as the upper surface 4 b of the concrete foundation 4.

次に、前記ねじ杆１３の固着について説明する。
前記ねじ杆１３は底板１１の孔１４を挿通して底板１１の上面１１ａ、下面１１ｂよりもそれぞれ上下に突出し、その突出した部分のねじ部１３ａに上ナット１５と下ナット１６をそれぞれ螺合して締め付けることで底板１１の上面１１ａ、下面１１ｂにそれぞれ押しつけてねじ軸１３を底板１１に固着してある。
前記底板１１の孔１４の内径はねじ軸１３の外径よりも大きく、孔１４とねじ軸１３との間には環状の隙間が形成される。 Next, the fixing of the screw rod 13 will be described.
The screw rod 13 is inserted through the hole 14 of the bottom plate 11 and protrudes up and down from the upper surface 11a and the lower surface 11b of the bottom plate 11, and the upper nut 15 and the lower nut 16 are screwed into the protruding thread portion 13a. The screw shaft 13 is fixed to the bottom plate 11 by being pressed against the upper surface 11a and the lower surface 11b of the bottom plate 11 respectively.
The inner diameter of the hole 14 in the bottom plate 11 is larger than the outer diameter of the screw shaft 13, and an annular gap is formed between the hole 14 and the screw shaft 13.

このようであるから、ねじ軸１３を孔１４に挿入し、上ナット１５と下ナット１６を螺合して締め付ける簡単な操作で筒状体１にねじ軸１３を固着してねじ孔１３ｂを底板１１に形成できるから、筒状体１の底板１１にねじ孔１３ｂを簡単に形成できる。   Thus, the screw shaft 13 is fixed to the cylindrical body 1 by a simple operation of inserting the screw shaft 13 into the hole 14 and screwing the upper nut 15 and the lower nut 16 together to tighten the screw hole 13b. 11, the screw hole 13 b can be easily formed in the bottom plate 11 of the cylindrical body 1.

また、上ナット１５を底板１１の上面１１ａに押しつけるとともに、下ナット１６を底板１１の下面１１ｂに押しつけて上下ナット１５，１６で底板１１を挟持することでねじ軸１３を固着してあるので、このねじ軸１３を底板１１に対して直角に固着できる。
したがって、このねじ軸１３の軸心に形成したねじ孔１３ｂが底板１４と直角であるから、そのねじ孔１３ｂに螺合したセパレータ２も底板１４と直角であり、筒状体１とセパレータ２を真直ぐに連結できる。 Since the upper nut 15 is pressed against the upper surface 11a of the bottom plate 11 and the lower nut 16 is pressed against the lower surface 11b of the bottom plate 11 and the bottom plate 11 is sandwiched between the upper and lower nuts 15 and 16, the screw shaft 13 is fixed. The screw shaft 13 can be fixed to the bottom plate 11 at a right angle.
Therefore, since the screw hole 13b formed in the shaft center of the screw shaft 13 is perpendicular to the bottom plate 14, the separator 2 screwed into the screw hole 13b is also perpendicular to the bottom plate 14, and the cylindrical body 1 and the separator 2 are connected to each other. Can be connected straight.

次に、筒状体１を詳細に説明する。
前記筒１０は、その外周面１０ｂが、上部が大径で下部が小径となるテーパー形状で、コンクリート基礎４から抜き出し易くしてある。
前記底板１１は筒１０と別体で、横板１１ｃと、その横板１１ｃの周縁に沿って一体的に設けたリング状の立上り片１１ｄを有する。
そして、筒１０の下部寄りを底板１１に嵌合して筒１０の下部開口端面１０ｃを横板１１ｃに接すると共に、筒１０の外周面１０ｂを立上り片１１ｄに接し、その立上り片１１ｄと筒１０の下部寄りをスポット溶接、ビス、ボルト・ナットなどの固着手段で固着してある。
前記上蓋１２は横板１２ａとリング状の垂下片１２ｂを有し、その垂下片１２ｂを筒１０の上部に嵌合して着脱自在に取付けてある。 Next, the cylindrical body 1 will be described in detail.
The outer peripheral surface 10b of the cylinder 10 has a tapered shape in which the upper part has a large diameter and the lower part has a small diameter, and is easily extracted from the concrete foundation 4.
The bottom plate 11 is separate from the cylinder 10 and includes a horizontal plate 11c and a ring-shaped rising piece 11d provided integrally along the periphery of the horizontal plate 11c.
The lower portion of the cylinder 10 is fitted to the bottom plate 11 so that the lower opening end surface 10c of the cylinder 10 is in contact with the horizontal plate 11c, and the outer peripheral surface 10b of the cylinder 10 is in contact with the rising piece 11d. The lower part is fixed by spot welding, screws, bolts and nuts or other fixing means.
The upper lid 12 has a horizontal plate 12a and a ring-like hanging piece 12b, and the hanging piece 12b is fitted to the upper part of the tube 10 and is detachably attached.

前述の凹陥部形成用治具を用いてコンクリート基礎に凹陥部を形成する際には、前述した従来技術と同様にして均しコンクリート（コンクリート基部４の底部４ａ）に穴５を形成し、この穴５に固着部材３を固着して取付け、この固着部材３にセパレータ２の下部を固着して取付け、そのセパレータ２の上部に筒状体１を連結して取付けると共に、その筒状体１の高さを調整してコンクリート基礎４の上面４ｂに合わせる。
そして、コンクリートを流し込んでコンクリート基礎４とする。この時、ねじ軸１３は上ロックナット２２でセパレータ２の上ねじ部２０にロックされているので、流し込んだコンクリートで筒状体１が動くことがない。セパレータ２から筒状体１を取り外して引き抜き、凹陥部６を形成する。
前述のように、筒状体１をセパレータ２から取り外しするには、上蓋１２を取り外し、上ナット１５に回転工具を掛けて回転することで筒状体１とともにねじ杆１３を回転してセパレータ２の上ねじ部２０からねじ杆１３を取り外しする。
なお、筒状体１をコンクリート基礎４から引き抜きせずに残存させ、その筒状体１を凹陥部とすることも可能である。 When the concave portion is formed on the concrete foundation using the above-described concave portion forming jig, the hole 5 is formed in the leveled concrete (the bottom portion 4a of the concrete base portion 4) in the same manner as the prior art described above. The fixing member 3 is fixedly attached to the hole 5, the lower part of the separator 2 is fixedly attached to the fixing member 3, the cylindrical body 1 is connected and attached to the upper part of the separator 2, and the cylindrical body 1 Adjust the height to match the upper surface 4b of the concrete foundation 4.
Then, concrete is poured into the concrete foundation 4. At this time, since the screw shaft 13 is locked to the upper screw portion 20 of the separator 2 by the upper lock nut 22, the cylindrical body 1 is not moved by the poured concrete. The cylindrical body 1 is removed from the separator 2 and pulled out to form the recessed portion 6.
As described above, in order to remove the cylindrical body 1 from the separator 2, the upper lid 12 is removed, and the upper nut 15 is rotated with a rotating tool to rotate the screw body 13 together with the cylindrical body 1 to rotate the separator 2. The screw rod 13 is removed from the upper screw portion 20.
It is also possible to leave the tubular body 1 without being pulled out from the concrete foundation 4 and to make the tubular body 1 into a recessed portion.

次に、本発明の他の実施の形態について説明する。
前記筒１０を、その外周面１０ｂに螺旋状突起を一体に有するものとしても良い。
このようにすれば、コンクリート基礎４から筒状体１を引き抜いた後に形成される凹陥部６が、その内周面に螺旋状溝を有する形状となるので、アンカーなどを保持し易い。 Next, another embodiment of the present invention will be described.
The cylinder 10 may have a spiral protrusion integrally on the outer peripheral surface 10b.
If it does in this way, since the recessed part 6 formed after pulling out the cylindrical body 1 from the concrete foundation 4 becomes a shape which has a spiral groove in the inner peripheral surface, it is easy to hold | maintain an anchor.

また、底板１１は横板１１ｃのみでも良い。この場合には筒１０を中央に穴を有する底面で閉塞されたものとし、その底面と底板１１を固着すると共に、ねじ杆１３と上ナット１５が筒１０の底面の穴から上方に突出するようにすることが好ましい。   Further, the bottom plate 11 may be only the horizontal plate 11c. In this case, it is assumed that the cylinder 10 is closed by a bottom surface having a hole in the center, the bottom surface and the bottom plate 11 are fixed, and the screw rod 13 and the upper nut 15 protrude upward from the hole in the bottom surface of the cylinder 10. It is preferable to make it.

また、底板１１は図３に示すように横板１１ｃと一対の縦板１１ｅとで上向きコ字形状としても良い。
このようにすれば、筒体１０を幅が小さく長さが大きく底面１０ｄを有する形状とすることができるので、幅が小さく長さが大きな凹陥部を形成でき、排水用溝、排水用集水ピットなどに好適である。 Further, as shown in FIG. 3, the bottom plate 11 may be formed in an upward U shape with a horizontal plate 11c and a pair of vertical plates 11e.
In this way, the cylindrical body 10 can be formed into a shape having a small width and a large length and having a bottom surface 10d, so that a concave portion having a small width and a large length can be formed. Suitable for pits and the like.

また、筒１０と底板１１を一体としても良い。
