Description

本発明は、コンクリート建造物を建造する際、スラブや梁等を構築する型枠に使用される大引き材を受けて固定するパイプサポート用大引き材受金物に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe support large-drawing material receiver for receiving and fixing a large-drawing material used in a formwork for constructing a slab, a beam or the like when building a concrete structure.

従来のパイプサポート用大引き材受金物として、例えば、特許文献１，２に記載されたものが提案されている。これらの従来のパイプサポート用大引き材受金物では、平板状の受板（特許文献２では支持板）と、パイプサポートが嵌る嵌合部（特許文献２では差し込みパイプ）からなり、特許文献１ではパイプサポート用大引き材受金物は平板状の受板に設けられた釘穴を介し釘で大引き材の下面に固定したり、特許文献２では支持板裏面の突起等で大引き材の下面に固定している。また、パイプサポートの上端部の当板が、パイプサポート用大引き材受金物の平板状の受板（特許文献２では支持板）を覆うように取付けられている。   As conventional pipe support large-drawing material receipts, for example, those described in Patent Documents 1 and 2 have been proposed. These conventional pull support materials for pipe support include a flat plate-like receiving plate (supporting plate in Patent Document 2) and a fitting portion (inserting pipe in Patent Document 2) into which the pipe support fits. Then, the pipe support large-drawing material receiver is fixed to the lower surface of the large-drawing material with a nail through a nail hole provided in a flat plate-shaped receiving plate. It is fixed on the bottom surface. Moreover, the abutment plate at the upper end of the pipe support is attached so as to cover a flat plate-like receiving plate (support plate in Patent Document 2) of the pipe support large-drawing material receiver.

しかし、上述の特許文献１に記載のパイプサポート用大引き材受金物では、大引き材の幅が変わった場合、嵌合部の中心と大引き材の幅方向の中心を合わせるのに手間がかかるという問題点がある。また、パイプサポートの上端部の当板がパイプサポート用大引き材受金物の受板と重なるように取付けられるので、パイプサポートを固定した後に、パイプサポート用大引き材受金物が大引き材に対し釘等で固定されたことを確認することができないという問題もある。また、パイプサポート用大引き材受金物を保管や運搬する際に重ねることが困難で、広い保管スペースが必要であったり、運搬に手間がかかるという問題もある。   However, in the pipe support large pulling material receiver described in Patent Document 1 described above, when the width of the large pulling material changes, it takes time to align the center of the fitting portion with the center of the large pulling material in the width direction. There is a problem that it takes. In addition, since the abutment plate at the upper end of the pipe support is attached so as to overlap the receiving plate of the pipe support large pulling material receiver, after the pipe support is fixed, the pipe support large pulling material receiver becomes the large pulling material. There is also a problem in that it cannot be confirmed that it is fixed with a nail or the like. In addition, it is difficult to stack the pipe support large-drawing material received and stored, and there is a problem that a large storage space is required and the transportation is troublesome.

また、特許文献２に記載のパイプサポート用大引き材受金物でも、特許文献１に記載のパイプサポート用大引き材受金物と同様に、大引き材の幅が変わった場合、嵌合部の中心と大引き材の幅方向の中心を合わせるのに手間がかかると共に、パイプサポート用大引き材受金物を保管や運搬する際に重ねることが困難で、広い保管スペースが必要であったり、運搬に手間がかかるという問題がある。特に、特許文献２に記載のパイプサポート用大引き材受金物では、パイプサポート用大引き材受金物の支持板に設けられた突起を打ち込んで大引き材に固定させるため、その固定度は弱く、安全性が低いという問題もある。   Further, in the pipe support large pulling material received article described in Patent Document 2, similarly to the pipe support large pulling material received article described in Patent Document 1, when the width of the large pulling material changes, the fitting portion It takes time and effort to align the center with the center of the pulling material in the width direction, and it is difficult to stack the large support material for pipe support when storing or transporting it. There is a problem that it takes time and effort. In particular, in the pipe support large-drawing material receiver described in Patent Document 2, since the protrusion provided on the support plate of the pipe support large-drawing material receiver is driven and fixed to the large pulling material, the fixing degree is weak. There is also a problem that safety is low.

また、このようなパイプサポート用大引き材受金物では、大引き材の下面に予め固定しておくため、安全性や作業性向上のため重量を軽量化することが望まれている。   Moreover, in such a pipe support large pulling material receiver, since it is fixed in advance to the lower surface of the large pulling material, it is desired to reduce the weight in order to improve safety and workability.

そこで、本発明は、このような問題点に着目してなされたもので、第１には、大引き材の幅が変わった場合でも簡単に嵌合部の中心と大引き材の幅方向の中心を合わせることができると共に、大引き材に対し釘等で固定されたことを容易に確認することができ、かつ、重量の増大を軽減でき、第２には、さらに広い保管スペースを必要とせずに効率良く重ねることができ、第３には、パイプサポートの上端部を簡単かつ確実に取付けることができるパイプサポート用大引き材受金物を提供することを目的とする。   Therefore, the present invention has been made paying attention to such problems. First, even when the width of the large pulling material changes, the center of the fitting portion and the width direction of the large pulling material can be easily determined. The center can be aligned, and it can be easily confirmed that it is fixed to the large pulling material with a nail, etc., and the increase in weight can be reduced. Secondly, a larger storage space is required. A third object of the present invention is to provide a pipe support large pulling material receiver that can be easily and reliably attached to the upper end of the pipe support.

上記目的を達成するため、本発明に係るパイプサポート用大引き材受金物は、コンクリート建造物を建造する際に使用される型枠の大引き材に取り付けられ、その下方の床面に立設されたパイプサポートの上端部が当接するパイプサポート用大引き材受金物であって、一方の面が大引き材の下面に当接可能な平面状に形成させると共に、他方の面がパイプサポートの上端部と嵌合可能な嵌合部が設けられた受板と、少なくとも大引き材の幅以上の間隔を空けて受板から一方側に起立された一対の起立板とを有し、その一対の起立板は、大引き材の側面に釘やネジ等の固定部材で固定するための固定部材通し孔が設けられており、当該金物を平面視した際に、受板と一対の起立板それぞれとの各境界線部上を通る一対の第１辺と、その一対の第１辺に直交する一対の第２辺とで構成された四辺形であって、かつ、受板の周囲を取り囲む最小の四辺形を想定し、その四辺形の第１辺方向における各起立板の長さは、それぞれ、その四辺形の一対の第１辺の長さよりも短くしたことを特徴とする。
ここで、前記四辺形の一の対角位置にはそれぞれ受板の角部が存在してそれら各角部から起立板が起立していると良い。
また、前記受板は、前記四辺形の他の対角位置にある受板の角部に相当する部分がそれぞれ切除されているとさらに良い。
また、前記受板には、少なくとも、前記四辺形の一対の第２辺のいずれか一方の側、もしくは両方の側から嵌合部の近傍にかけて該嵌合部の幅よりも大きな切欠き部が設けられているとさらに良い。
また、前記一対の起立板が、それぞれ受板を超えて他方側に延設され、その延設された部分にパイプサポートの上端部に設けられた当板が係止可能な係止部が設けられているとさらに良い。 In order to achieve the above object, a pipe support large pulling material receiver according to the present invention is attached to a large pulling material of a formwork used when building a concrete building, and is erected on a floor surface below the same. The pipe support large pulling material receiver with which the upper end of the pipe support abuts is formed so that one surface is in a flat shape capable of abutting against the lower surface of the large pulling material, and the other surface is the pipe support A receiving plate provided with a fitting portion that can be fitted to the upper end portion, and a pair of upright plates that are erected on one side from the receiving plate with an interval of at least the width of the large pulling material. The upright plate is provided with a fixing member through hole for fixing with a fixing member such as a nail or a screw on the side surface of the large pulling material, and when the hardware is viewed in plan, the receiving plate and the pair of upright plates respectively And a pair of first sides passing through each boundary line part and the pair of first sides The length of each upright plate in the first side direction of the quadrilateral, which is a quadrilateral composed of a pair of second sides orthogonal to the side and envisions the smallest quadrangle surrounding the periphery of the receiving plate Each is characterized by being shorter than the length of the pair of first sides of the quadrilateral.
Here, it is preferable that a corner portion of the receiving plate exists at one diagonal position of the quadrilateral and the upright plate stands up from each corner portion.
Further, it is further preferable that the receiving plate is cut out at portions corresponding to corner portions of the receiving plate at other diagonal positions of the quadrilateral.
Further, the receiving plate has at least a cutout portion larger than the width of the fitting portion from one side of the pair of second sides of the quadrilateral or from both sides to the vicinity of the fitting portion. It is even better if it is provided.
In addition, the pair of upright plates are extended to the other side beyond the receiving plates, respectively, and the extended portion is provided with a locking portion capable of locking the plate provided at the upper end portion of the pipe support. Even better.

本発明に係るパイプサポート用大引き材受金物では、受板の両側には少なくとも大引き材の幅以上の間隔を空けて起立した一対の起立板を設けたので、大引き材の幅が細いものに変わった場合でもこの金物を回転させてそれぞれの起立板を大引き材の側面に当接させることにより嵌合部の中心と大引き材の幅方向の中心を簡単に合わせることができる。
また、その一対の起立板には、釘やネジ等の固定部材が通る固定部材通し孔を設けたので、パイプサポート用大引き材受金物にパイプサポートを取り付けた後でも、大引き材に対し釘等で固定されたことを側方から容易に確認することができる。
また、パイプサポート用大引き材受金物を平面視した際に、受板と一対の起立板それぞれとの各境界線部上を通る一対の第１辺と、その一対の第１辺に直交する一対の第２辺とで構成された四辺形であって、かつ、受板の周囲を取り囲む最小の四辺形を想定し、その四辺形の第１辺方向における各起立板の長さは、それぞれ、その四辺形の一対の第１辺の長さよりも短くしたので、その四辺形の第１辺の長さと同じ長さの起立板を設ける場合よりも重量を軽減できる。
また、一対の起立板を、上述の四辺形の一の対角位置にある受板の各角部にそれぞれ起立させた場合には、パイプサポート用大引き材受金物よりも幅の細い大引き材に取り付けるためにこの金物を回転させた際に、小さい回転量で大引き材の側面に一対の起立板の端部を当接させることができると共に、大引き材からパイプサポート用大引き材受金物が張り出す量を少なくすることができる。さらに、受板を上記四辺形の他の対角位置にある受板の角部に相当する部分をそれぞれ切除した形状にすれば、上記の張り出し量を最小限にすることができる。
また、受板に、少なくとも、前記四辺形の一対の第２辺のいずれか一方の側、もしくは、両方の側から嵌合部の近傍にかけて該嵌合部の幅よりも大きな切欠き部を設けた場合には、広い保管スペースを必要とせずに効率良く複数のパイプサポート用大引き材受金物を重ねて保管することができる。
また、一対の起立板を、それぞれ受板を超えて他方側に延設させ、その延設した部分にパイプサポートの上端部に設けられた当板が係止可能な係止部を設けた場合には、パイプサポートをパイプサポート用大引き材受金物に簡単かつ確実に係止することができる。 In the pipe support large pulling material receiver according to the present invention, since the pair of upright plates standing at least the width of the large pulling material is provided on both sides of the receiving plate, the width of the large pulling material is thin. Even if it changes to a thing, the center of a fitting part and the center of the width direction of a large pulling material can be easily match | combined by rotating this hardware and making each stand plate contact | abut to the side surface of a large pulling material.
In addition, the pair of upright plates are provided with fixing member through-holes through which fixing members such as nails and screws pass, so even after the pipe support is attached to the pipe support large pulling material receiver, It can be easily confirmed from the side that it is fixed with a nail or the like.
In addition, when the pipe support large-drawing material receiver is viewed in plan, the pair of first sides passing through the boundary portions between the receiving plate and each of the pair of upright plates and the pair of first sides are orthogonal to each other. Assuming a quadrilateral composed of a pair of second sides and surrounding the periphery of the receiving plate, the length of each upright plate in the first side direction of the quadrilateral is Since the length of the first side of the quadrilateral is shorter than the length of the first side of the quadrilateral, the weight can be reduced as compared with the case where an upright plate having the same length as the first side of the quadrilateral is provided.
In addition, when the pair of upright plates are raised at the respective corners of the receiving plate at one diagonal position of the above-mentioned quadrilateral, the pulling is narrower than the pipe support large pulling material receiving material. When this hardware is rotated for attachment to the material, the ends of the pair of upright plates can be brought into contact with the side surfaces of the large pulling material with a small amount of rotation, and the pulling material for the pipe support from the large pulling material It is possible to reduce the amount of the received object protruding. Furthermore, if the receiving plate is shaped by cutting away the portions corresponding to the corners of the receiving plate at other diagonal positions of the quadrilateral, the amount of overhang can be minimized.
In addition, the receiving plate is provided with a notch portion larger than the width of the fitting portion from at least one side of the pair of second sides of the quadrilateral or from both sides to the vicinity of the fitting portion. In this case, it is possible to efficiently store a plurality of large support materials for pipe support, without requiring a large storage space.
Also, when a pair of upright plates are extended to the other side beyond the receiving plate, respectively, and the extended portion is provided with a locking portion capable of locking the plate provided at the upper end of the pipe support. In this case, the pipe support can be easily and reliably locked to the pipe support large-drawing material receiver.

次に、本発明に係る実施形態のパイプサポート用大引き材受金物（以下、「金物」と略す。）１について図面を参照して説明する。   Next, a pipe support large-drawing material receiver (hereinafter abbreviated as “metal”) 1 according to an embodiment of the present invention will be described with reference to the drawings.

金物１は、コンクリート建造物を建造する際に使用される型枠の大引き材２に取り付けられ、その下方の床面に立設されたパイプサポート３が取り付けられるもので、図１〜図４に示すように、受板１１と、一対の起立板１２，１２から構成されている。特に、本実施形態では、一枚の鋼板を図５に示すような形状にカットした後、受板１１と一対の起立板１２，１２それぞれとの境界線部Ｌ１，Ｌ１に沿って一方側に折り曲げて受板１１に対し各起立板１２，１２をほぼ９０度の角度で起立させることによって形成される。   The hardware 1 is attached to a large pulling material 2 of a formwork used when a concrete building is constructed, and a pipe support 3 erected on the floor surface below is attached. As shown in FIG. 2, the receiving plate 11 and a pair of upright plates 12 and 12 are used. In particular, in the present embodiment, after cutting a single steel plate into a shape as shown in FIG. 5, on one side along boundary line portions L 1 and L 1 between the receiving plate 11 and the pair of upright plates 12 and 12, respectively. It is formed by bending and raising the upright plates 12 and 12 at an angle of about 90 degrees with respect to the receiving plate 11.

受板１１は、図６に示すように大引き材２の下面に固定されるもので、後述する図８（ａ），（ｂ）に示すように円筒状のパイプサポート３の上端部３１に挿入されて嵌り合う円筒状の嵌合部１１ａが設けられている。そのため、嵌合部１１ａの幅、すなわち外径は、パイプサポート３の内径よりも小さくなる。   The receiving plate 11 is fixed to the lower surface of the large pulling material 2 as shown in FIG. 6, and is attached to the upper end 31 of the cylindrical pipe support 3 as shown in FIGS. A cylindrical fitting portion 11a that is inserted and fitted is provided. Therefore, the width of the fitting portion 11 a, that is, the outer diameter is smaller than the inner diameter of the pipe support 3.

そして、図１や図３に示すように、この金物１を平面視した際に、受板１１と一対の起立板１２，１２それぞれとの各境界線部Ｌ１，Ｌ１上を通る一対の第１辺Ｓ１，Ｓ１と、その一対の第１辺Ｓ１，Ｓ１に直交し、受板１１の周囲を取り囲む一対の第２辺Ｓ２，Ｓ２とで構成された最小の四辺形Ｒを想定する。   As shown in FIGS. 1 and 3, when the hardware 1 is viewed in plan, a pair of first passages passing over the boundary portions L1 and L1 between the receiving plate 11 and the pair of upright plates 12 and 12 respectively. Assume a minimum quadrilateral R composed of sides S1 and S1 and a pair of second sides S2 and S2 that are orthogonal to the pair of first sides S1 and S1 and surround the periphery of the receiving plate 11.

すると、この金物１では、四辺形Ｒの一の対角位置Ｃ１，Ｃ１にそれぞれ受板１１の角部が存在してそれら各角部から起立板１２，１２が起立している。また、四辺形Ｒの他の対角位置Ｃ２，Ｃ２にある受板１１の角部に相当する部分がそれぞれ斜めに切除されている。   Then, in this hardware 1, corner portions of the receiving plate 11 exist at one diagonal position C 1, C 1 of the quadrilateral R, and the upright plates 12, 12 stand up from the respective corner portions. Further, the portions corresponding to the corners of the receiving plate 11 at the other diagonal positions C2, C2 of the quadrilateral R are respectively cut off obliquely.

そのため、この金物１によれば、後述する図６（ｃ）に示すように、金物１の幅より細い大引き材２の取り付ける場合には、金物１を回転させて一対の起立板１２，１２の先端部が大引き材２の側面に当接するように取り付けられるが、このとき金物１を小さい回転量で大引き材２に取り付けることができると共に、大引き材２から金物１が水平方向へ張り出す突出量（長さ）Ｗ３を最小限にすることができ、型枠周辺での作業を安全に行うことができる。   Therefore, according to this hardware 1, as shown in FIG. 6C described later, when attaching a large pulling material 2 thinner than the width of the hardware 1, the hardware 1 is rotated and the pair of upright plates 12, 12. At this time, the hardware 1 can be attached to the large pulling material 2 with a small amount of rotation, and the metal 1 from the large pulling material 2 in the horizontal direction can be attached to the large pulling material 2. The protruding amount (length) W3 that protrudes can be minimized, and the work around the mold can be performed safely.

また、この金物１では、図１や図３に示すように、受板１１には、四辺形Ｒの一対の第２辺Ｓ２，Ｓ２の一方の側から嵌合部１１ａの近傍を通り、四辺形Ｒの一対の第１辺Ｓ１，Ｓ１の一方の側にかけて切り欠かれた、嵌合部１１ａの幅よりも大きな切欠き部１１ｃが設けられている。   Moreover, in this hardware 1, as shown in FIG.1 and FIG.3, the receiving plate 11 passes through the vicinity of the fitting part 11a from one side of a pair of 2nd side S2, S2 of quadrilateral R, and four sides A notch portion 11c larger than the width of the fitting portion 11a, which is notched toward one side of the pair of first sides S1, S1 of the shape R, is provided.

そのため、図９に示すように、金物１の切欠き部１１ｃに別の金物１の嵌合部１１ａが嵌ることになるので、複数の金物１を一列の状態で重ねることができる。その結果、多くの金物１を広い保管スペースを必要とせずに効率良く重ねて保管することができる。なお、切欠き部１１ｃは、四辺形Ｒの一対の第２辺Ｓ２，Ｓ２の一方の側から嵌合部１１ａの近傍を通って、同じ四辺形Ｒの一対の第２辺Ｓ２，Ｓ２の一方の側にかけて切り欠かれた形態でも良く、また、嵌合部１１ａを挟んで四辺形Ｒの一対の第２辺Ｓ２，Ｓ２の両方の側に設けても良い。   Therefore, as shown in FIG. 9, since the fitting part 11a of another hardware 1 fits into the notch part 11c of the hardware 1, a plurality of hardware 1 can be stacked in a row. As a result, many metal objects 1 can be efficiently stacked and stored without requiring a wide storage space. In addition, the notch part 11c passes through the vicinity of the fitting part 11a from one side of the pair of second sides S2, S2 of the quadrilateral R, and one of the pair of second sides S2, S2 of the same quadrangle R. It is also possible to have a form cut out toward the side of the pair, and it may be provided on both sides of the pair of second sides S2, S2 of the quadrilateral R across the fitting portion 11a.

一方、一対の起立板１２，１２は、大引き材２の最大幅以上の間隔を空けて受板１１から起立して設けられており、その間隔は、図１に示すように四辺形Ｒの第２辺Ｓ２，Ｓ２の長さＷ２となる。ここで、大引き材２の幅は、通常、９０ｍｍ〜１０５ｍｍのものが使用されているので、本実施形態の金物１では、一対の起立板１２，１２の間隔である長さＷ２を説明の便宜上、大引き材２の最大幅の１０５ｍｍとする。   On the other hand, the pair of upright plates 12 and 12 are provided upright from the receiving plate 11 with an interval equal to or larger than the maximum width of the large pulling material 2, and the interval is as shown in FIG. It becomes the length W2 of the second side S2, S2. Here, since the thing of 90 mm-105 mm is normally used for the width | variety of the large pulling material 2, the length W2 which is the space | interval of a pair of upright plates 12 and 12 is demonstrated in the hardware 1 of this embodiment. For convenience, the maximum width of the large pulling material 2 is set to 105 mm.

よって、幅１０５ｍｍの大引き材２にこの金物１を固定する場合には、図６（ｂ）に示すように一対の起立板１２，１２それぞれの対向する内側全面を大引き材２の側面に当接させて釘等の固定部材４により固定することができる。   Therefore, when fixing the hardware 1 to the large pulling material 2 having a width of 105 mm, as shown in FIG. 6 (b), the entire inner surfaces of the pair of upright plates 12, 12 facing the side surfaces of the large pulling material 2. It can be contacted and fixed by a fixing member 4 such as a nail.

これに対し、この金物１を幅９０ｍｍの大引き材２に固定する場合には、図６（ｃ）に示すように、金物１を回転（図６（ｃ）では時計回り方向に回転）させて、一対の起立板１２，１２それぞれ対向する内側面の先端部のみを大引き材２の側面に当接させて釘等の固定部材４により固定することができる。   On the other hand, when fixing the hardware 1 to the large pulling material 2 having a width of 90 mm, the hardware 1 is rotated (clockwise in FIG. 6C) as shown in FIG. 6C. Thus, only the front end portions of the inner side surfaces facing each of the pair of upright plates 12 and 12 can be brought into contact with the side surfaces of the large pulling material 2 and fixed by a fixing member 4 such as a nail.

以上のことにより、この金物１によれば、大引き材２の幅が変わった場合でもサイズの異なる金物１を用意することなく取り付けることができると共に、嵌合部１１ａの中心と大引き材２の幅方向の中心とを簡単に合わせることができる。その結果、図７（ａ）に示すように、この金物１にパイプサポート３の上端部３１を嵌合させた際に、大引き材２の幅方向の中心にパイプサポート３を取り付けることができるため、パイプサポート３は、大引き材２をバランス良く支持することができる。   As described above, according to the hardware 1, even when the width of the large pulling material 2 is changed, the hardware 1 having a different size can be attached without being prepared, and the center of the fitting portion 11 a and the large pulling material 2 can be attached. Can be easily aligned with the center in the width direction. As a result, as shown in FIG. 7A, when the upper end portion 31 of the pipe support 3 is fitted to the hardware 1, the pipe support 3 can be attached to the center in the width direction of the large pulling material 2. Therefore, the pipe support 3 can support the large pulling material 2 with a good balance.

また、四辺形Ｒの第１辺Ｓ１，Ｓ１の方向における各起立板１２，１２の長さＷ０，Ｗ０は、それぞれ、その四辺形Ｒの一対の第１辺Ｓ１，Ｓ１の長さＷ１，Ｗ１よりも短くしている。   The lengths W0 and W0 of the upright plates 12 and 12 in the direction of the first side S1 and S1 of the quadrilateral R are the lengths W1 and W1 of the pair of first sides S1 and S1 of the quadrilateral R, respectively. Shorter than that.

そのため、四辺形Ｒの第１辺Ｓ１，Ｓ１の長さＷ１，Ｗ１と同じ長さの起立板１２，１２を設ける場合よりも重量を軽減できる。   Therefore, the weight can be reduced as compared with the case where the upright plates 12 and 12 having the same length as the lengths W1 and W1 of the first sides S1 and S1 of the quadrilateral R are provided.

また、一対の起立板１２，１２には、図２に示すように、それぞれ釘やネジ等の固定部材４が通る固定部材通し孔１２ａ，１２ａが設けられている。さらに、この金物１は後述する図７（ａ）や図８（ａ）等に示すように、一対の起立板１２，１２の固定部材通し孔１２ａ，１２ａに釘等の固定部材４を挿入して大引き材２の側面に固定されるので、図７（ａ），（ｂ）や図８（ａ），（ｂ）等に示すように、パイプサポート３がこの金物１に取り付けられて受板１１がパイプサポート３の上部の当板３ａに覆われても、金物１の一対の起立板１２，１２が大引き材２の側面に当接されているため、金物１が固定部材４で固定されたか否かを一対の起立板１２，１２の固定部材通し孔１２ａ，１２ａによって容易に確認することができる。なお、本実施形態の金物１のように、受板１１にも固定部材通し孔１１ｂ，１１ｂを設ければ、さらに大引き材２との固定度を増すことができる。   Further, as shown in FIG. 2, the pair of upright plates 12 and 12 are provided with fixing member through holes 12a and 12a through which the fixing member 4 such as a nail or a screw passes. Further, as shown in FIGS. 7A and 8A, which will be described later, the hardware 1 has a fixing member 4 such as a nail inserted into the fixing member through holes 12a and 12a of the pair of upright plates 12 and 12. The pipe support 3 is attached to the hardware 1 as shown in FIGS. 7 (a) and 7 (b) and FIGS. 8 (a) and 8 (b). Even if the plate 11 is covered with the abutment plate 3 a on the upper part of the pipe support 3, the pair of upright plates 12, 12 of the hardware 1 are in contact with the side surfaces of the large pulling material 2, so that the hardware 1 is fixed by the fixing member 4. It can be easily confirmed by the fixing member through holes 12a, 12a of the pair of upright plates 12, 12 whether or not they are fixed. In addition, if the fixing member through-holes 11b and 11b are provided also in the receiving plate 11 like the metal object 1 of this embodiment, the fixing degree with the large pulling material 2 can be further increased.

また、一対の起立板１２，１２は、図２や図６（ａ）、図７（ａ）等に示すように、それぞれ受板１１を超えて他方側、すなわち受板１１の嵌合部１１ａ側に延設されており、その延設した部分にパイプサポート３の上部の当板３ａを係止する係止部１２ｂ，１２ｂが設けられている。そのため、パイプサポート３を金物１に釘等で固定する手間を省くことができる。ちなみに、係止部１２ｂ，１２ｂは一対の起立板１２，１２それぞれと一体化されているため、例えば、受板１１の一部を切り起こして係止部を設けた場合には、受板１１における係止部の切り起こし部分が断面欠損となり強度的に弱くなるという不具合が生じるが、この金物１ではそのような不具合の発生を防止できる。   Further, as shown in FIG. 2, FIG. 6A, FIG. 7A, and the like, the pair of upright plates 12, 12 are each over the receiving plate 11, that is, the fitting portion 11 a of the receiving plate 11. Locking portions 12b and 12b for locking the abutting plate 3a on the upper portion of the pipe support 3 are provided on the extended portion. Therefore, the trouble of fixing the pipe support 3 to the hardware 1 with a nail or the like can be saved. Incidentally, since the locking portions 12b and 12b are integrated with the pair of upright plates 12 and 12, for example, when the locking plate is provided by cutting and raising a part of the receiving plate 11, the receiving plate 11 However, this hardware 1 can prevent the occurrence of such a problem.

次に、以上のように構成された金物１の使用方法を説明する。   Next, the usage method of the hardware 1 comprised as mentioned above is demonstrated.

スラブや床等の型枠を施工する際は、まず、地組の段階で大引き材２に金物１を釘やビス等の固定部材４によって固定し、この金物１が取り付けられた大引き材２を所定の位置に仮設する。   When constructing a formwork such as a slab or a floor, first, the metal fitting 1 is fixed to the large pulling material 2 by a fixing member 4 such as a nail or a screw at the ground assembly stage, and the large pulling material to which the hardware 1 is attached. 2 is temporarily installed at a predetermined position.

次に、図７（ａ）に示すように大引き材２に固定されたこの金物１にパイプサポート３を取り付ける場合には、図７（ｂ）に示すように一対の起立板１２，１２それぞれの係止部１２ｂ，１２ｂを避けるようにパイプサポート３の上端部３１を斜めにしてパイプサポート３の上端部３１を受板１１の嵌合部１１ａに挿入させ、パイプサポート３の上部の当板３ａを受板１１に当接させた後、矢印の方向に回転させて、図８（ａ），（ｂ）に示すように、一対の起立板１２，１２の係止部１２ｂ，１２ｂに係止させることで、パイプサポート３を取り付けることができる。   Next, when the pipe support 3 is attached to the hardware 1 fixed to the large pulling material 2 as shown in FIG. 7A, a pair of upright plates 12 and 12 are respectively shown in FIG. 7B. The upper end 31 of the pipe support 3 is inclined so as to avoid the locking portions 12b, 12b, and the upper end 31 of the pipe support 3 is inserted into the fitting portion 11a of the receiving plate 11, so 3a is brought into contact with the receiving plate 11 and then rotated in the direction of the arrow to engage the engaging portions 12b and 12b of the pair of upright plates 12 and 12, as shown in FIGS. The pipe support 3 can be attached by stopping.

The above operation is performed for all the hardware 1 fixed to each large pulling material 2, and then the on-site supervisor checks whether the hardware 1 is fixed. At this time, the hardware 1 and the large pulling material 2 are fixed by a pair of standing plates 12, 12 that stand up from the receiving plate 11 of the hardware 1 and extend along both side surfaces of the large pulling material 2. The presence or absence can be easily confirmed. In addition, although the pipe support 3 etc. are demolished after concrete placement, since the hardware 1 is fixed to the large pulling material 2 even after dismantling, it can be moved to another place and used.
