Description

【０００１】
【発明の属する技術分野】
この発明は、支保工用の部材連結装置の改良に関するもので、構造が簡単で、しかも安価に製造できるようにした部材連結装置に関するものである。
【０００２】
【従来の技術】
一般に工事現場等における足場や型枠等を支持する支保工は、適当間隔を置いて支柱を立設すると共に、各支柱を水平ブレースや筋交いなどの補強部材で連結することによって所要強度の構造体を構成するものである。そして、上記支柱と補強部材の連結には部材連結装置が利用されている。
【０００３】
図３は、出願人が先に特開平７−５４５０４号として出願、開示した従来の部材連結装置の一例の平面図を示すものである。図において、ａは支柱（Ｐ）に配設される嵌合筒体であり、ｂ、ｂ・・はその嵌合筒体ａの外周に９０度置きに取り付けた受金具で、これに筋交い等を固定する。また、ｃは嵌合筒体ａと支柱（Ｐ）とにわたって挿通される固定ボルトで、嵌合筒体ａに支柱（Ｐ）を挿入した後この固定ボルトを挿入して支柱を固定するものである。
【０００４】
各受金具ｂ、ｂ・・は、鋼板を平面視コ字状に折曲形成して互いに平行な板部材ｄ、ｅを構成すると共に一方の板部材ｅの外側側面にガイド板ｆを設け、このガイド板ｆおよび上記板部材ｄ、ｅにわたってピン孔ｇを貫設してロックピンｈを挿通したものである。この受金具ｂは折曲部を嵌合筒体ａの外周に溶接して固定し、また、ガイド板ｆも板部材ｅに溶接して取り付ける。
【０００５】
ガイド板ｆのピン孔ｇ内には規制ピンｉが水平方向に突出して設けられ、一方、ピン孔ｇに挿通するロックピンｈの外周面には、上記規制ピンｉが嵌入してロックピンｈが上記ピン孔ｇをその軸方向に進退するように規制するガイド溝ｊと、ロックピンｈがピン孔ｇに進入した状態でロックピンｈを軸周りに回転させると共にロックピンｈの軸方向の進退を規制する固定溝ｋが刻設されている。さらに、ロックピンｈの固定溝ｋ側の端部にはロックピンｈの軸と直交し、かつ、上記ガイド溝ｊの深さ方向と同じ方向に棒状のハンドルｍが遊嵌されている。
【０００６】
かかる構成の部材連結装置は、まず、嵌合筒体ａに支柱（Ｐ）を挿入して固定ボルトｃで固定する。次に、ロックピンｈの先端部を一方の板部材ｅ側に位置するまで引き出し、例えば筋交い等（図示せず）の端部を板部材ｄ、ｅ間に差し込む。そして、筋交いの先端部のピン孔を板部材ｄ、ｅのピン孔ｇと一致させロックピンｈを押し込むと筋交いは仮固定される。
【０００７】
ロックピンｈはガイド溝ｊに沿って前進し、その先端が他方の板部材ｄにかかるまで完全に押し込んだ後、ハンドルｍを介して固定溝ｋに沿って軸周り下方向に回転させると、ロックピンｈの進退は固定溝ｋに制限され、筋交いは完全に固定される。ハンドルｍは手を離すと自重によって垂直方向に位置し、このとき上記ガイド溝ｊは下向きに位置することになるので、水平方向の規制ピンｉとガイド溝ｊの位置が一致してロックピンｈが抜け出す方向に移動することはない。
【０００８】
【発明が解決しようとする課題】
上記構成の従来の部材連結装置は、ロックピンが板部材の一方に進退可能に支持されているので、構造体の組立、解体の作業性を向上させるものであると共に、ボルト、ナット等で部材を連結していた場合に比べてロックピンが落下するおそれがなく、作業の安全性を向上するものであった。
【０００９】
しかしながら、上記従来の部材連結装置を製造するには、平面視コ字状に折曲した各板部材ｄ、ｅの一方にガイド板ｆをそれぞれ溶接して固定し、さらにガイド板の側面に孔を穿設して内端がピン孔ｇに突出するように規制ピンｉを埋め込むという手段が採られていた。
従って、その受金具ｂの製造作業には多大な手間と費用を要するものであり、溶接状態を均質にするには高度な技術を要するなど、なお改良の余地があった。
【００１０】
本願発明は上記従来の部材連結装置の問題点に鑑みてなされたものであり、特に受金具の部品数を減少させ、製造が容易かつ安価で、充分な強度を有する部材連結装置を提供することを目的とするものである。
【００１１】
【課題を解決するための手段】
上記目的を達成するため、本発明は、支柱と嵌合する嵌合筒体１の外周面の所望位置に１乃至複数個の受金具２を取り付け、該受金具２に貫設したピン孔８にガイド突片９を介してロックピン７を進退可能に支持してなる支保工の部材連結装置において、受金具２は鋼板を平面視Ｓ字または逆Ｓ字状に折曲して互いに平行な一対の板部材４、５およびガイド板部材６を構成すると共に、ガイド板部材６にガイド突片９を残して各板部材４、５、６にわたるピン孔８を貫設し、このピン孔８に挿通するロックピン７の外周面には、軸方向に、上記ガイド突片９が嵌入してロックピン７がピン孔８を軸方向に進退するように規制するガイド溝１１を設け、さらにガイド溝１１の一端に連続して軸周方向に固定溝１２を凹設してロックピン７を進退可能に支持するという手段を採用した。
【００１２】
また、ガイド溝１１の先端にガイド突片９を係止する閉止部１１ａを設けるという手段、さらに、上記ロックピンの後端に、その軸と直交する方向にハンドルを遊嵌するという手段も採用した。
【００１３】
上記構成の部材連結装置は、受金具２を、鋼板を平面視Ｓ字または逆Ｓ字状に折曲して一対の板部材４、５およびガイド板部材６を形成すると共に、ガイド突片９を残してピン孔８を貫設したものであるから、従来のようにガイド板を溶接し、規制ピンを埋め込むといった手間を完全に排除することが可能となり、製造コストを大幅に低減することが可能となるものである。
【００１４】
また、ガイド板部材に溶接部分がないので、該部に均質かつ充分な強度を得られるものである。
【００１５】
さらに、ロックピン７のガイド溝１１の先端に閉止部１１ａを設けガイド突片９を係止するようにしたので、ロックピン７は抜け落ちることなく進退可能に支持され、構造体の組立、解体の作業性を向上させるものであると共に、ロックピンが落下するおそれがなく、作業の安全性を向上するという作用効果も期待できる。
【００１６】
また、ロックピン７の後端にハンドル１３を遊嵌したものは、筋交い等を固定したときにハンドル１３が自重によって垂直方向に垂れ下がり、ガイド溝１１とガイド突片９の位置がずれてロックピン７がピン孔８から不用意に抜け出すことが防止できる。
【００１７】
【発明の実施の形態】
以下、本発明に係る部材連結装置の好ましい実施の形態を図面に従って説明する。図１は本発明に係る部材連結装置の平面図、図２は受金具のうちの一個の分解斜視図である。図において、１は支柱（Ｐ）に配設される嵌合筒体であり、２、２・・は該嵌合筒体１の外周面に９０度置きに取り付けられる受金具である。また、３は嵌合筒体１と支柱（Ｐ）とにわたって挿通される固定ボルトで、嵌合筒体１に支柱（Ｐ）を挿入した後この固定ボルト３を挿入して支柱を固定するものである。なお、受金具２は筋交い等（図示せず）を連結するものであり、図では９０度置きに４個取り付けたものを例示しているが、これに限定するものではなく、その取り付け個数は必要に応じて任意の数が選定される。
【００１８】
各受金具２、２・・は鋼板を平面視において逆Ｓ字状（Ｓ字状でもよい）に折曲形成して互いに平行な一対の板部材４、５およびガイド板部材６を構成すると共に、各板部材４、５、６にわたって下述するロックピン７が挿通するピン孔８、８・・を貫設したものである。このとき外側のガイド板部材６のピン孔８には水平方向に突出するガイド突片９を残してピン孔８を穿設する。この受金具２は嵌合筒体１の外周面に９０度置きに溶接部１０によって取り付ける。
【００１９】
上記ピン孔８に挿通するロックピン７は、先端部分を先細として板部材４、５間に挿入する筋交い等（図示せず）の先端に設けられるピン孔に嵌入しやすくする。また、ロックピン７の外周面には、軸方向に沿って、上記ガイド突片９が嵌入してロックピン７が上記ピン孔８を軸方向に進退するように規制するガイド溝１１を設け、該ガイド溝の先端は閉止部１１ａとしてガイド突片９が当接するようにする。さらに、このガイド溝１１の後端と連続して軸周方向に固定溝１２を凹設する。この固定溝１２は、上記ガイド突片９が嵌入してロックピン７が完全にピン孔８に進入した状態でロックピン７を軸周りに回転させると共に、ガイド溝１１と連続する部分以外ではロックピン７の軸方向の移動を規制するものである。なお、ロックピン７は、ガイド溝１１の先端閉止部１１ａでガイド突片９が係止されるから、ガイド板部材６に進退可能に支持されると共に、ピン孔８から脱落することはない。
【００２０】
また、１３はロックピン７の後端部にその軸と直交し、かつ、上記ガイド溝１１の深さ方向と同じ方向に設けられた穴に遊嵌されるハンドルで、端部１３ａを圧潰して抜け落ちないようにしたものである。
【００２１】
次に、この受金具の使用態様について概説すると、まず、嵌合筒体１を支柱（Ｐ）に嵌着し固定ボルト３を両者間に挿通して支柱に固定する。次に、ロックピン７の先端部が真ん中の板部材５側に位置するまで（ガイド突片９がガイド溝の閉止部１１ａと当接する位置まで）引き出し、筋交い等の端部を板部材４、５間に差し込んで筋交いの端部のピン孔と板部材のピン孔８とを一致させ、ロックピン７を押し込むと筋交いは仮固定される。
【００２２】
ロックピン７をガイド溝１１に沿って前進させ、先端が他方の板部材４にかかるまで完全に押し込んだ後、ハンドル１３を介して固定溝１２に沿って軸周り下方向に回転させる。これによってロックピンの進退が固定溝１２で制限され、筋交いを完全に固定することができる。ハンドル１３は手を離すと自重によって垂直方向に垂れ下がったままで圧潰された端部１３ａで係止され、このとき、ガイド溝１１は下向きに位置しているので、振動等によってガイド突片９とガイド溝１１の位置が一致するおそれはなく、ロックピン７が抜け出る方向に移動することはない。なお、このロックピン７の作用は前述した従前の部材連結装置のロックピンと共通するものである。
【００２３】
【発明の効果】
以上述べたように、上記構成に係る本発明の部材連結装置は、受金具として鋼板をＳ字または逆Ｓ字状に折曲して板部材４、５およびガイド板部材６を構成し、さらにピン孔内にガイド突片も一体に構成するようにしたものであるから、従来のように別途ガイド板を板部材に溶接したり、ガイド板の側面に穴を設けて規制ピンを埋め込むと言った製造上の手間を完全に排除することが可能となり、製造コストを極めて低くすることが可能となった。また、ガイド板部材６を板部材４、５と一体に形成しているので、溶接部分がなく、均質かつ充分な強度の受金具を得ることが可能である。
【００２４】
また、筋交い等の端部を板部材間に挿入し、ロックピン７をスライドさせ、さらに回転させて筋交いを固定するようにしているので、筋交いの位置合わせが容易で、短時間に作業ができるようになって作業性が向上する。
【００２５】
さらに、ロックピン７はガイド突片９とガイド溝の閉止部１１ａの係合によって脱落を防止し、ガイド板部材６に進退可能に支持されているので、組み立て作業時にロックピン７を別途用意して持ち運ぶ必要がなく、ロックピン７が高所から落下するおそれもないので作業の安全性を高めることができる。

It constitutes. A member connecting device is used to connect the support column and the reinforcing member.
[0003]
FIG. 3 shows a plan view of an example of a conventional member connecting device that was previously filed and disclosed by the applicant as Japanese Patent Application Laid-Open No. 7-54504. In the figure, a is a fitting cylinder disposed on the support column (P), b, b... Are receiving brackets attached to the outer periphery of the fitting cylinder a at intervals of 90 degrees, To fix. Further, c is a fixing bolt inserted through the fitting cylinder a and the column (P), and after inserting the column (P) into the fitting cylinder a, the fixing bolt is inserted to fix the column. is there.
[0004]
Each of the metal fittings b, b,... Is formed by bending a steel plate into a U-shape in plan view to form parallel plate members d, e and a guide plate f on the outer side surface of one plate member e. A pin hole g is provided through the guide plate f and the plate members d and e, and a lock pin h is inserted therethrough. The metal fitting b is fixed by welding the bent portion to the outer periphery of the fitting cylinder a, and the guide plate f is also welded to the plate member e.
[0005]
A regulation pin i is provided in the pin hole g of the guide plate f so as to protrude in the horizontal direction. On the other hand, the regulation pin i is fitted on the outer peripheral surface of the lock pin h inserted through the pin hole g. The guide groove j that restricts the pin hole g to advance and retreat in the axial direction, and the lock pin h is rotated around the axis with the lock pin h entering the pin hole g and the axial direction of the lock pin h A fixed groove k that regulates advancement and retraction is provided. Further, a rod-like handle m is loosely fitted at the end of the lock pin h on the fixing groove k side in a direction perpendicular to the axis of the lock pin h and in the same direction as the depth direction of the guide groove j.
[0006]
In the member connecting device having such a configuration, first, the support column (P) is inserted into the fitting cylinder a and fixed with the fixing bolt c. Next, the front end of the lock pin h is pulled out until it is located on the one plate member e side, and for example, the end of a brace (not shown) is inserted between the plate members d and e. When the pin hole at the front end of the brace is made to coincide with the pin hole g of the plate members d and e, and the lock pin h is pushed in, the brace is temporarily fixed.
[0007]
When the lock pin h moves forward along the guide groove j and is completely pushed in until the tip of the lock pin h engages with the other plate member d, the lock pin h is rotated downward about the axis along the fixed groove k via the handle m. The advancement / retraction of the lock pin h is limited to the fixing groove k, and the brace is completely fixed. When the handle m is released, the handle m is positioned in the vertical direction by its own weight. At this time, the guide groove j is positioned downward, so that the positions of the horizontal restriction pin i and the guide groove j coincide with each other and the lock pin h Will not move in the direction of exiting.
[0008]
[Problems to be solved by the invention]
In the conventional member connecting device having the above-described structure, the lock pin is supported by one of the plate members so as to be able to advance and retract. Compared with the case where the two are connected, there is no fear that the lock pin will drop, and the safety of the work will be improved.
[0009]
However, in order to manufacture the above-described conventional member coupling device, the guide plate f is welded and fixed to one of the plate members d and e bent in a U shape in plan view, and a hole is formed on the side surface of the guide plate. And a restriction pin i is embedded so that the inner end protrudes into the pin hole g.
Therefore, the manufacturing work of the metal fitting b requires a lot of labor and cost, and there is still room for improvement, such as high technology required to make the welded state uniform.
[0010]
The present invention has been made in view of the problems of the above-described conventional member coupling device, and in particular, to provide a member coupling device that has a sufficient strength, is easy to manufacture, is inexpensive, and has a reduced number of parts. It is intended.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, one or a plurality of metal fittings 2 are attached to desired positions on the outer peripheral surface of the fitting cylinder 1 to be fitted with the support columns, and the pin holes 8 are provided through the metal fittings 2. In the supporting member connecting device in which the lock pin 7 is supported so as to be able to advance and retreat via the guide projection piece 9, the support fitting 2 is bent parallel to each other by bending the steel plate into a S shape or an inverted S shape in a plan view. A pair of plate members 4 and 5 and a guide plate member 6 are configured, and a pin hole 8 extending through each of the plate members 4, 5 and 6 is provided in the guide plate member 6, leaving the guide protrusions 9. A guide groove 11 is provided on the outer peripheral surface of the lock pin 7 inserted through the guide pin 11 for restricting the guide pin 9 so that the guide protrusion 9 is inserted in the axial direction so that the lock pin 7 advances and retracts in the axial direction. A locking groove 12 is recessed in the axial circumferential direction continuously to one end of the groove 11 and the lock pin 7 is advanced and retracted. It adopted the means that support to capacity.
[0012]
Further, means for providing a closing portion 11a for locking the guide protrusion 9 at the tip of the guide groove 11, and means for loosely fitting a handle to the rear end of the lock pin in a direction perpendicular to the axis thereof are also employed. did.
[0013]
In the member connecting device having the above-described configuration, the receiving metal fitting 2 is bent in an S-shape or an inverted S-shape in plan view to form a pair of plate members 4 and 5 and a guide plate member 6, and a guide projection piece 9. Since the pin hole 8 is provided so as to leave a gap, it is possible to completely eliminate the trouble of welding the guide plate and embedding the regulation pin as in the conventional case, which can greatly reduce the manufacturing cost. It is possible.
[0014]
Further, since the guide plate member has no welded portion, a uniform and sufficient strength can be obtained at the portion.
[0015]
Further, since the closing portion 11a is provided at the tip of the guide groove 11 of the lock pin 7 so as to lock the guide projection piece 9, the lock pin 7 is supported so as to be able to advance and retreat without falling off, and the assembly and disassembly of the structure can be performed. In addition to improving workability, there is no possibility that the lock pin will drop, and an effect of improving work safety can be expected.
[0016]
In the case where the handle 13 is loosely fitted to the rear end of the lock pin 7, when the brace is fixed, the handle 13 hangs down in the vertical direction due to its own weight, and the position of the guide groove 11 and the guide protruding piece 9 is shifted. 7 can be prevented from coming out of the pin hole 8 carelessly.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a member connecting device according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a member connecting device according to the present invention, and FIG. 2 is an exploded perspective view of one of the metal fittings. In the figure, reference numeral 1 denotes a fitting cylinder disposed on the column (P), and 2, 2... Are receiving brackets attached to the outer peripheral surface of the fitting cylinder 1 every 90 degrees. Reference numeral 3 denotes a fixing bolt inserted through the fitting cylinder 1 and the column (P). After the column (P) is inserted into the fitting cylinder 1, the fixing bolt 3 is inserted to fix the column. It is. Note that the bracket 2 connects braces or the like (not shown), and in the figure, four pieces are attached at intervals of 90 degrees, but the present invention is not limited to this. An arbitrary number is selected as necessary.
[0018]
Each of the brackets 2, 2,... Forms a pair of plate members 4 and 5 and a guide plate member 6 parallel to each other by bending the steel plate into an inverted S shape (or S shape) in plan view. .. Are inserted through the plate members 4, 5, 6 through which the lock pins 7 described below are inserted. At this time, the pin hole 8 is formed in the pin hole 8 of the outer guide plate member 6 leaving the guide protrusion 9 protruding in the horizontal direction. The metal fitting 2 is attached to the outer peripheral surface of the fitting cylinder 1 by a welded portion 10 every 90 degrees.
[0019]
The lock pin 7 inserted into the pin hole 8 is easily fitted into a pin hole provided at the tip of a brace or the like (not shown) inserted between the plate members 4 and 5 with the tip portion tapered. A guide groove 11 is provided on the outer peripheral surface of the lock pin 7 to restrict the lock pin 7 from moving forward and backward in the axial direction by inserting the guide protrusion 9 along the axial direction. The guide protrusion 9 is brought into contact with the end of the guide groove as a closing portion 11a. Further, the fixed groove 12 is recessed in the axial circumferential direction continuously with the rear end of the guide groove 11. The fixing groove 12 is configured to rotate the lock pin 7 around the axis in a state where the guide protruding piece 9 is inserted and the lock pin 7 is completely inserted into the pin hole 8, and is locked at a portion other than a portion continuous with the guide groove 11. The movement of the pin 7 in the axial direction is restricted. The lock pin 7 is supported by the guide plate member 6 so as to be able to advance and retreat, and does not fall off from the pin hole 8 since the guide protrusion 9 is locked by the tip closing portion 11a of the guide groove 11.
[0020]
Reference numeral 13 denotes a handle which is loosely fitted in a hole provided at the rear end portion of the lock pin 7 in a direction perpendicular to the axis thereof and in the same direction as the depth direction of the guide groove 11, and crushes the end portion 13a. So that it will not fall out.
[0021]
Next, the usage of the metal fitting will be outlined. First, the fitting cylinder 1 is fitted to the support column (P), and the fixing bolt 3 is inserted between them and fixed to the support column. Next, the lock pin 7 is pulled out until the front end portion of the lock pin 7 is located on the middle plate member 5 side (to the position where the guide protrusion 9 abuts against the guide groove closing portion 11a), and the end of the brace is extended to the plate member 4, When the pin hole 8 of the plate member and the pin hole 8 of the plate member are made to coincide with each other by inserting between 5 and the lock pin 7 is pushed in, the brace is temporarily fixed.
[0022]
The lock pin 7 is advanced along the guide groove 11 and completely pushed in until the tip is engaged with the other plate member 4, and then rotated downward along the fixed groove 12 via the handle 13. As a result, the advancement / retraction of the lock pin is limited by the fixing groove 12, and the bracing can be completely fixed. When the handle 13 is released, the handle 13 is locked by the crushed end 13a while hanging down in the vertical direction due to its own weight. At this time, the guide groove 11 is positioned downward, so that the guide protrusion 9 and the guide 9 are vibrated by vibration or the like. There is no possibility that the positions of the grooves 11 coincide with each other, and the lock pin 7 does not move in the direction of coming out. The action of the lock pin 7 is common to the lock pin of the conventional member connecting device described above.
[0023]
【The invention's effect】
As described above, the member coupling device of the present invention according to the above configuration forms the plate members 4 and 5 and the guide plate member 6 by bending a steel plate as a bracket into an S shape or an inverted S shape, Since the guide protrusion is also configured integrally in the pin hole, it is said that a guide plate is welded to the plate member separately as in the past, or a hole is provided on the side surface of the guide plate to embed the restriction pin. In addition, it is possible to completely eliminate the manufacturing effort, and the manufacturing cost can be extremely reduced. In addition, since the guide plate member 6 is formed integrally with the plate members 4 and 5, there is no welded portion, and it is possible to obtain a metal fitting having a uniform and sufficient strength.
[0024]
Further, since the end of a brace is inserted between the plate members, the lock pin 7 is slid and further rotated to fix the brace, the brace can be positioned easily and work can be done in a short time. As a result, workability is improved.
[0025]
Further, since the lock pin 7 is prevented from falling off by engagement of the guide protrusion 9 and the guide groove closing portion 11a and is supported by the guide plate member 6 so as to be able to advance and retract, a lock pin 7 is separately prepared during assembly work. Therefore, the safety of the work can be improved because there is no possibility of the lock pin 7 falling from a high place.
