Description

本発明は、コンクリートなどの天井、壁面、床面に電線ケーブルやワッシャ等を留めたり、天井コンクリートなどの下方に軽量物を吊下げたり、固定したりするのに供される吊下金具等の留付け具に関する。   The present invention relates to a hanging metal fitting used for fastening an electric cable or washer to a ceiling, wall surface or floor surface of concrete or the like, or to suspend or fix a lightweight object below the ceiling concrete or the like. Related to fasteners.

一般に、空調設備工事などで天井コンクリートに軽量物を吊下げるためには、まず留付け具(通称Z金具)を天井コンクリートに固定しておき、この留付け具に全ネジボルトを螺着し、この全ネジボルトに軽量の対象物を吊下げるということが行なわれている。そして、留付け具を天井のコンクリートに固定するときは、留付け具に予め孔を開けておき、この穴を狙って釘打機でピンを打ち込み、ピンで留付け具を固定する。   In general, in order to suspend lightweight objects on ceiling concrete for air conditioning construction work, etc., firstly fasten a fastener (commonly known as a Z bracket) to the ceiling concrete, and screw all the screw bolts onto this fastener. It is practiced to suspend a lightweight object on all screw bolts. Then, when fixing the fastener to the concrete on the ceiling, a hole is made in the fastener in advance, a pin is driven with a nailing machine aiming at the hole, and the fastener is fixed with the pin.

ところが、穴を開けただけの金具では、下から天井に向けた釘打機で上記穴を狙ってピンを打ち込むのは非常に難しい。   However, it is very difficult to drive a pin aiming at the hole with a nailing machine from the bottom to the ceiling with a metal fitting with a hole.

そこで、穴狙いを容易にするため、金具の穴の部分に合成樹脂製のガイドを取り付け、このガイドには穴の周囲に釘打機の円弧状先端部を収容する受け溝を形成しておき、この受け溝の内外側の溝壁に釘打機の先端部を係合させて保持し、上記先端部を正しい位置に安定した状態で打ち込むようにした技術が知られている(特許文献1参照)。   Therefore, in order to facilitate the aiming of the hole, a synthetic resin guide is attached to the hole portion of the metal fitting, and a receiving groove for accommodating the arcuate tip of the nailing machine is formed around the hole in this guide. A technique is known in which the tip of a nailing machine is engaged and held on the inner and outer groove walls of the receiving groove, and the tip is driven into a correct position in a stable state (Patent Document 1). reference).

また、金具の穴に弾性を有する合成樹脂製の円板状ガイドを取り付け、この円板状ガイドの外側から釘打機の先端の円筒状部分を嵌め込むように係合させて保持した状態で打ち込むようにした技術も知られている(特許文献2参照)。

In addition, a disc-shaped guide made of synthetic resin having elasticity is attached to the hole of the metal fitting, and the cylindrical portion at the tip of the nailing machine is fitted and held from the outside of the disc-shaped guide. A technique of driving in is also known (see Patent Document 2).
European Patent Publication No. 15538345 US Pat. No. 7,093,338

しかしながら、上述の技術はいずれも、ピンなどのファスナーを打ち込むときに樹脂製のガイドが留付け具とファスナーとの間に挟まって障害物となり、このためファスナーの貫入量が少なくなってしまうという問題がある。   However, both of the above-described techniques have a problem in that when a fastener such as a pin is driven, a resin guide is sandwiched between the fastener and the fastener, resulting in an obstacle, and the amount of fastener penetration is reduced. There is.

さらに、留付け具の底面は平らであるから、底面全面でコンクリート面に接面する留付け具の場合、コンクリート面には小さいながら凹凸があるので、接面したときに不安定であり、傾きやすいという問題があった。   In addition, since the bottom surface of the fastener is flat, in the case of a fastener that contacts the concrete surface over the entire bottom surface, the concrete surface is small but uneven, so it is unstable when in contact and tilted. There was a problem that it was easy.

本発明は上記問題点に鑑み、釘打機の先端のノーズ部に確実に保持され、ファスナーの打込みを良好にガイドすることができるとともに、天井コンクリート等に強く固定することができる留付け具を提供することをその課題とする。   In view of the above problems, the present invention provides a fastener that is securely held by the nose portion at the tip of the nailing machine, can guide the driving of fasteners well, and can be firmly fixed to ceiling concrete or the like. The issue is to provide.

前記課題を解決するため、請求項1に係る発明は、釘打機のノーズ部から打ち出されたファスナーにより被打ち込み材に固定される留付け具であって、上記ファスナーを挿通する挿通孔に、上記ノーズ部の内側に挿入されて上記ファスナーをガイドするためのガイド部材を設けるとともに、上記ガイド部材には、一端が上記挿通孔に固定されたガイド軸部と、ガイド軸部の他端側から放射状に形成されて可撓性を有する案内羽根とを備え、かつ上記案内羽根の先端を結んだ円の径を上記釘打機のノーズ部の内径よりも大きくしたことを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 is a fastening tool fixed to a driven material by a fastener driven out from a nose portion of a nailing machine, and an insertion hole through which the fastener is inserted, A guide member is provided for guiding the fastener by being inserted inside the nose portion. The guide member includes a guide shaft portion having one end fixed to the insertion hole, and a guide shaft portion from the other end side of the guide shaft portion. And a guide blade having flexibility formed radially, and a diameter of a circle connecting the tips of the guide blade is made larger than an inner diameter of a nose portion of the nailing machine.

請求項2に係る発明は、請求項1において、上記留付け具が、釘打機本体に対してファスナーの打ち込み方向に相対的に移動可能に設けられた外側ノーズ部と釘打機本体に固定された内側ノーズ部との2重構造を有する釘打機により打ち込まれる留付け具であって、上記案内羽根の先端を結んだ円の径を上記釘打機の外側ノーズ部の内径よりも大きくするとともに、上記ガイド軸部の外周面に複数のガイド片を形成し、該ガイド片の先端を結んだ円の径を上記外側ノーズ部の内径よりもやや小さくしたことを特徴とする。   According to a second aspect of the present invention, in the first aspect, the fastening device is fixed to the outer nose portion and the nail driver main body provided so as to be movable relative to the nail driver main body in the fastener driving direction. A fastener that is driven by a nail driver having a double structure with the inner nose portion formed, wherein the diameter of a circle connecting the tips of the guide vanes is larger than the inner diameter of the outer nose portion of the nail driver In addition, a plurality of guide pieces are formed on the outer peripheral surface of the guide shaft portion, and the diameter of the circle connecting the tips of the guide pieces is slightly smaller than the inner diameter of the outer nose portion.

請求項3に係る発明は、請求項1又は2において、上記ガイド軸部の中心には上記釘打機から打ち出されたファスナーを案内するガイド穴10が形成されていることを特徴とする。   The invention according to claim 3 is characterized in that, in claim 1 or 2, a guide hole 10 for guiding the fastener driven out from the nailing machine is formed in the center of the guide shaft portion.

請求項4に係る発明は、請求項2又は3において、上記ガイド片は隣り合う上記案内羽根の間に形成されていることを特徴とする。   According to a fourth aspect of the present invention, in the second or third aspect, the guide piece is formed between the adjacent guide blades.

請求項5に係る発明は、請求項1において、上記被打ち込み材に固定されたときに上記被打ち込み材に当接する面には、複数の回り止め用突起が形成されていることを特徴とする。   The invention according to claim 5 is characterized in that, in claim 1, a plurality of anti-rotation protrusions are formed on a surface that comes into contact with the driven material when fixed to the driven material. .

請求項6に係る発明は、請求項5において、上記複数の突起は、上記ファスナー挿通孔の近傍に設けられた複数の突起と、該ファスナー挿通孔から離れた位置に設けられた複数の突起とであることを特徴とする。   The invention according to claim 6 is the invention according to claim 5, wherein the plurality of protrusions include a plurality of protrusions provided in the vicinity of the fastener insertion hole, and a plurality of protrusions provided at positions away from the fastener insertion hole. It is characterized by being.

請求項7に係る発明は、請求項6において、上記ファスナー挿通孔の近傍に設けられた複数の突起と、上記ファスナー挿通孔から離れた位置に設けられた複数の突起とは、上記ファスナー挿通孔を挟んで互いに反対側に配置されていることを特徴とする。   The invention according to claim 7 is the fastener insertion hole according to claim 6, wherein the plurality of protrusions provided in the vicinity of the fastener insertion hole and the plurality of protrusions provided at positions away from the fastener insertion hole are It is characterized by being arranged on the opposite sides with respect to each other.

請求項1に係る発明によれば、留付け具のガイド部材には、一端が上記挿通孔に固定されたガイド軸部と、ガイド軸部の他端側から放射状に形成されて可撓性を有する案内羽根とを設けるとともに、該案内羽根の先端を結んだ円の径を上記釘打機のノーズ部の内径よりも大きくしたから、留付け具を片手に取り、上記ガイド軸部を釘打機のノーズ部に嵌め込んで留付け具を下に向けたとき、案内羽根がその基部から折れ曲り、その先端がノーズ部の内面に斜めに係合するので、案内羽根の弾性反発力と逆止作用とにより留付け具はノーズ部に保持され、脱落することがない。また、ガイド軸部の垂直性が維持された状態で打ち込むことができるので、座屈、打ち損じ等が発生しにくい。   According to the first aspect of the present invention, the guide member of the fastener has a guide shaft portion, one end of which is fixed to the insertion hole, and is radially formed from the other end side of the guide shaft portion so as to be flexible. Since the diameter of the circle connecting the tips of the guide vanes is made larger than the inner diameter of the nose portion of the nailing machine, the fastening tool is held in one hand, and the guide shaft portion is nailed. The guide vane bends from its base and engages with the inner surface of the nose when it is inserted into the machine's nose. The fastening device is held in the nose portion by the stopping action, and does not fall off. Further, since the guide shaft portion can be driven in a state in which the perpendicularity is maintained, buckling, breakage, and the like are unlikely to occur.

次に、留付け具を上にして釘打機によりファスナーをコンクリート等に打ち込めばよいから、打ち込み作業が楽である。釘打機により打ち出されたファスナーは案内羽根によりノーズ部の中心に保持されたガイド軸部を貫通してファスナーの挿通孔を通ってコンクリート等に打ち込まれる。同時に、打込み時の反動によってノーズ部は天井コンクリート等の表面から離反する。このため、案内羽根とガイド軸部はファスナーの頭部によって外側に押し打され、圧潰されてファスナーの頭部の外側に逃げる。したがって、打込みの障害になりにくく、ファスナーの貫入量は十分に確保されるから、留付け具を天井コンクリート等に強く固定することができる。   Next, it is only necessary to drive the fastener into concrete or the like with a nailing machine with the fastening tool facing up, so that the driving operation is easy. The fastener driven out by the nailing machine passes through the guide shaft portion held at the center of the nose portion by the guide blades and is driven into concrete or the like through the insertion hole of the fastener. At the same time, the nose portion separates from the surface of the ceiling concrete or the like due to the recoil at the time of driving. For this reason, the guide vane and the guide shaft portion are pushed outward by the head of the fastener, are crushed and escape to the outside of the head of the fastener. Therefore, it is hard to become a hindrance to driving and a sufficient amount of fasteners can be secured, so that the fastening tool can be strongly fixed to ceiling concrete or the like.

請求項2に係る発明によれば、ガイド軸部を釘打機のノーズ部に嵌め込んで装着したとき、案内羽根がその基部から撓んで曲り、その先端が外側ノーズ部の内面に斜めに係合するので、案内羽根の弾性反発力と逆止作用とにより留付け具はノーズ部に保持され、脱落することがない。   According to the second aspect of the present invention, when the guide shaft portion is fitted and attached to the nose portion of the nailing machine, the guide vane bends and bends from its base portion, and its tip is obliquely engaged with the inner surface of the outer nose portion. Therefore, the fastening tool is held by the nose portion due to the elastic repulsion force and the check action of the guide vanes, and does not fall off.

次に、留付け具とともにノーズ部の先端を天井コンクリート等の表面の所定位置に当接させ、さらにファスナーを打ち込むにあたって、釘打機の外側ノーズ部を上記表面に押し付ける。これにより、釘打機とともに内側ノーズ部が相対的に移動して内側ノーズ部の先端のガイド部材に当たる。ファスナーが内側ノーズ部内を多少傾いて射出されることがあったとしても、ガイド軸部の外周面には複数のガイド片が形成され、該ガイド片の先端を結んだ円の内径が上記外側ノーズ部の内径と略同じに形成されているので、ガイド片によってガイド軸部は内側ノーズ部の中心に保持される。したがって、内側ノーズ部から打ち出されたファスナーは確実にガイド軸部の中心を通って挿通孔に案内され、確実に打ち出される。   Next, the tip of the nose portion is brought into contact with a predetermined position on the surface of the ceiling concrete or the like together with the fastener, and the outer nose portion of the nailing machine is pressed against the surface when the fastener is driven. As a result, the inner nose portion moves relative to the nailing machine and hits the guide member at the tip of the inner nose portion. Even if the fastener is ejected with a slight inclination inside the inner nose portion, a plurality of guide pieces are formed on the outer peripheral surface of the guide shaft portion, and the inner diameter of the circle connecting the tips of the guide pieces is the outer nose. The guide shaft portion is held at the center of the inner nose portion by the guide piece. Therefore, the fastener driven out from the inner nose portion is surely guided through the center of the guide shaft portion to the insertion hole and is reliably driven out.

請求項3に係る発明によれば、ガイド軸部の中心には上記釘打機から打ち出されたファスナーを案内するガイド穴が形成されているので、ピンはガイド穴の内側を通過する。そして、垂直のガイド軸部に案内され、確実に留付け具の固定片の挿通孔を通って天井コンクリート等の表面に垂直に打ち込まれる。ファスナーが打ち込まれるとき、ガイド軸部の内面は広げられ、ガイド片と案内羽根も外側に押し広げられるが、打込み時の反動によって内側ノーズ部は天井コンクリート等の表面から離反するので、ガイド部材の主たる部分は挿通孔の外側に逃げて広がるから、ピンの頭部の裏面と固定片との間にガイド部材は圧潰された部分を除いてほとんど残らない。したがって、ファスナーの貫入量は十分に確保される。しかも、ガイド部材のガイド軸部自体は肉薄で、ガイド片が補強している構造であるから、ガイド軸部は垂直性の維持性能は高いが、外方への広がりに対する強度は小さいので、ガイド軸部をピンがガイド穴を通るときの通過抵抗は非常に小さい。したがって、パワーロスが少なく、吊下金具を天井コンクリート等に強く固定することができる。   According to the invention of claim 3, since the guide hole for guiding the fastener driven out from the nailing machine is formed at the center of the guide shaft portion, the pin passes through the inside of the guide hole. Then, it is guided by the vertical guide shaft portion and reliably driven vertically into the surface of the ceiling concrete or the like through the insertion hole of the fixing piece of the fastening tool. When the fastener is driven, the inner surface of the guide shaft portion is expanded and the guide piece and the guide vane are also pushed outward, but the inner nose portion is separated from the surface of the ceiling concrete or the like by the reaction during driving, so the guide member Since the main part escapes and spreads outside the insertion hole, the guide member hardly remains between the back surface of the head of the pin and the fixed piece except for the crushed part. Therefore, the penetration amount of the fastener is sufficiently ensured. In addition, since the guide shaft portion of the guide member itself is thin and the guide piece is reinforced, the guide shaft portion has a high perpendicularity maintaining performance, but the strength against outward spread is small. The passage resistance when the pin passes through the guide hole in the shaft portion is very small. Therefore, there is little power loss and a hanging metal fitting can be firmly fixed to ceiling concrete etc.

請求項4に係る発明によれば、ガイド片は隣り合う案内羽根の間に形成されているから、案内羽根とガイド片とが互いに他の干渉をうけることなくそれぞれその機能を十分に発揮することができる。   According to the fourth aspect of the present invention, since the guide piece is formed between the adjacent guide blades, the guide blade and the guide piece perform their functions sufficiently without receiving other interference with each other. Can do.

請求項5に係る発明によれば、上記被打ち込み材に固定されたときに上記被打ち込み材に当接する面には、複数の回り止め用突起が形成されているから、ファスナーによって固定されたとき、ガイド部材が潰されて裏側に回ったり、被打ち込み材のコンクリート面に凹凸があったり、留付け具に反りがあったりなどにより、留付け具の裏面が被打ち込み材面に密着しない状態になっていても、突起が被打ち込み材に強く押し付けられるので、留付け具は摩擦力により強固に保持され、ファスナーを中心に回すように外力が作用しても、留付け具は回らないので、作業者は留付け具がしっかりと被打ち込み材に固定されているということが確信でき、信頼性が向上する。   According to the fifth aspect of the present invention, when a plurality of anti-rotation protrusions are formed on the surface that comes into contact with the driven material when fixed to the driven material, when fixed by a fastener If the guide member is crushed and turned to the back side, the concrete surface of the material to be driven is uneven, the warping tool is warped, etc., the back surface of the fastening tool is not in close contact with the surface of the material to be driven. Even if it is, since the projection is strongly pressed against the workpiece, the fastening tool is firmly held by the frictional force, and even if an external force acts like turning the fastener around, the fastening tool does not turn. The operator can be confident that the fastening tool is firmly fixed to the driven material, and the reliability is improved.

請求項6に係る発明によれば、上記複数の突起は、上記ファスナー挿通孔の近傍に設けられた複数の突起と、該ファスナー挿通孔から離れた位置に設けられた複数の突起とであるから、留付け具はこれらの複数の突起の互いの協働作用による摩擦力で強固に保持されるので、回り止め効果が高い。   According to the invention of claim 6, the plurality of protrusions are a plurality of protrusions provided in the vicinity of the fastener insertion hole and a plurality of protrusions provided at positions away from the fastener insertion hole. Since the fastening tool is firmly held by the frictional force due to the mutual action of the plurality of protrusions, the detent effect is high.

また、ファスナー挿通孔の近傍に設けられた複数の突起は回り止め効果は大きいが留付け具が傾きやすい。これに対し、ファスナー挿通孔から離れた位置に設けられた複数の突起は回り止め効果はそれほど大きくないが、留付け具を安定に保持する効果が高い。したがって、これらの突起のバランスの良い配置で、留付け具の回り止めと傾きの防止を効果的に達成することができる。   In addition, the plurality of protrusions provided in the vicinity of the fastener insertion hole have a large anti-rotation effect, but the fastener is easily tilted. On the other hand, the plurality of protrusions provided at positions away from the fastener insertion holes are not so effective in preventing rotation, but have a high effect of stably holding the fastener. Therefore, with a well-balanced arrangement of these protrusions, it is possible to effectively achieve prevention of rotation and inclination of the fastener.

請求項7に係る発明は、ファスナー挿通孔の近傍に設けられた複数の突起と、上記ファスナー挿通孔から離れた位置に設けられた複数の突起とを、上記ファスナー挿通孔を挟んで互いに反対側に配置した構造であるから、留付け具の回り止めと傾きの防止をより一層効果的に実現することができる。   In the invention according to claim 7, the plurality of protrusions provided in the vicinity of the fastener insertion hole and the plurality of protrusions provided at positions away from the fastener insertion hole are opposite to each other across the fastener insertion hole. Therefore, it is possible to more effectively realize the anti-rotation of the fastener and the prevention of the inclination.

本発明の実施の形態を図面に基づいて説明する。図1においてAは留付け具の一例として吊下金具を示す。そして、この吊下金具Aにピンa(ファスナー)を打ち出す釘打機(図示せず)は、釘打機本体に対してピンaの打ち込み方向に相対的に移動可能に設けられた筒状の外側ノーズ部(コンタクトトップ)1aと釘打機本体に固定された筒状の内側ノーズ部1bとの2重構造を有する釘打機である。なお、ピンaにおいて、a1は他のピンとの連結材であり、a2はピンaが内側ノーズ部1b内で傾くのを防ぐガイドで、いずれも合成樹脂製の部材である。   Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, A shows a hanging metal fitting as an example of a fastener. A nailing machine (not shown) for driving a pin a (fastener) into the hanging metal fitting A is a cylindrical shape provided so as to be relatively movable in the driving direction of the pin a with respect to the nailing machine body. A nailing machine having a double structure of an outer nose part (contact top) 1a and a cylindrical inner nose part 1b fixed to a nailing machine body. In addition, in the pin a, a1 is a connection material with another pin, a2 is a guide which prevents the pin a from inclining within the inner nose portion 1b, and both are members made of synthetic resin.

内側ノーズ部1bはピンaの射出口を有し、釘打機本体と一体に形成されている。外側ノーズ部1aは、内側ノーズ部1bの外側に、ピンaの打込み方向に沿って摺動自在に配置されたコンタクトアーム(図示せず)の先端に設けられている。また、外側ノーズ部1aは、通常は内側ノーズ部1bの先端よりも突出するようにバネ付勢され、天井躯体Pのコンクリート等の被打ち込み材に押し付けることにより、バネ付勢に抗して相対的に後退し、上記内側ノーズ部1bの先端とともに上記躯体の表面に当接するように構成されている。   The inner nose portion 1b has an injection port for the pin a, and is formed integrally with the nailing machine body. The outer nose portion 1a is provided on the outer end of the inner nose portion 1b at the tip of a contact arm (not shown) that is slidably disposed along the driving direction of the pin a. Further, the outer nose portion 1a is normally spring-biased so as to protrude from the tip of the inner nose portion 1b, and is pressed against a material to be driven such as concrete of the ceiling casing P, thereby resisting against the spring bias. It is configured to move backward and come into contact with the surface of the housing together with the tip of the inner nose portion 1b.

上記吊下金具Aは金属製で、図7にも示されるように、ネジ穴2が形成された取付片3とピンa(ファスナー)の挿通孔4が形成された固定片5とを段差部6を介してZ字状に形成したもので、固定片5のピンaの挿通孔4にはガイド部材7が取り付けられている。   The hanging metal fitting A is made of metal, and as shown in FIG. 7, the mounting piece 3 in which the screw hole 2 is formed and the fixing piece 5 in which the insertion hole 4 for the pin a (fastener) is formed are stepped portions. The guide member 7 is attached to the insertion hole 4 of the pin a of the fixed piece 5.

上記ガイド部材7は弾性を有する合成樹脂製の部材で、図2(a)〜(d)および図3に示されるように、一端8aが上記挿通孔4に固定されたガイド軸部8と、ガイド軸部8の他端から放射状に形成されて可撓性を有する3枚の案内羽根9とを備えている。上記案内羽根9の先端を結んだ円O1の径は上記釘打機の外側ノーズ部1aの内径よりも大きくなるように形成されている。   The guide member 7 is a member made of synthetic resin having elasticity, and as shown in FIGS. 2A to 2D and FIG. 3, a guide shaft portion 8 having one end 8 a fixed to the insertion hole 4, and Three guide vanes 9 are formed radially from the other end of the guide shaft portion 8 and have flexibility. The diameter of the circle O1 connecting the tips of the guide vanes 9 is formed to be larger than the inner diameter of the outer nose portion 1a of the nailing machine.

ガイド軸部8の中心には上記釘打機から打ち出されたピンaを案内するガイド穴10が形成されている。ガイド穴10の先端にはピンaの先端を内側に案内する案内面11が形成されている。また、ガイド軸部8の基端8aは挿通孔4に嵌合できるように、少し小径に形成されている。   At the center of the guide shaft portion 8, a guide hole 10 for guiding the pin a driven out from the nailing machine is formed. A guide surface 11 that guides the tip of the pin a inward is formed at the tip of the guide hole 10. Further, the base end 8 a of the guide shaft portion 8 is formed with a small diameter so that it can be fitted into the insertion hole 4.

ガイド穴10はガイド軸部8の中心を貫通してもよいが、上記挿通孔4に嵌めこまれた側の端部8aを中実に構成してもよい。さらに、ガイド軸部8は垂直性をアップさせるため、十分な長さ(例えば7〜10mm程度)とするのが好ましい。   The guide hole 10 may penetrate the center of the guide shaft portion 8, but the end portion 8 a on the side fitted in the insertion hole 4 may be solid. Further, it is preferable that the guide shaft portion 8 has a sufficient length (for example, about 7 to 10 mm) in order to improve the verticality.

次に、上記ガイド軸部8の外周面に複数のリブ状のガイド片12が放射状に形成されている。該ガイド片12の先端を結んだ円の径は内側ノーズ部1bの内径よりもやや小さく(約0.1〜0.5mm程度)形成されている。ガイド片12の先端には外側に傾斜して上記内側ノーズ部1bの先端を案内する傾斜部13が形成されている。   Next, a plurality of rib-shaped guide pieces 12 are radially formed on the outer peripheral surface of the guide shaft portion 8. The diameter of the circle connecting the tips of the guide pieces 12 is slightly smaller (about 0.1 to 0.5 mm) than the inner diameter of the inner nose portion 1b. An inclined portion 13 is formed at the distal end of the guide piece 12 so as to be inclined outward and guide the distal end of the inner nose portion 1b.

なお、ガイド片12は連続したリブ状でなく、ガイド軸部8の外周面の長手方向に沿って複数の突片又は突起(図示せず)を形成した態様であってもよい。   The guide piece 12 may not be a continuous rib, but may be a form in which a plurality of protruding pieces or protrusions (not shown) are formed along the longitudinal direction of the outer peripheral surface of the guide shaft portion 8.

上記構成によれば、釘打ち込みにあたり、まず図4のように吊下金具Aを手に取り外側ノーズ部1aにガイド部材7の先端を嵌め込んで装着する。このとき案内羽根9が撓みながらその基部から曲がり、その先端がノーズ部の内面に斜めに係合するので、吊下金具を下に向けても、案内羽根9の弾性反発力と逆止作用とにより吊下金具Aは外側ノーズ部1aに脱落することなく安定に保持される。   According to the above configuration, when nailing, as shown in FIG. 4, first, the hanging metal fitting A is picked up and the tip of the guide member 7 is fitted and attached to the outer nose portion 1a. At this time, the guide blade 9 bends from its base while being bent, and its tip engages obliquely with the inner surface of the nose portion. Thus, the hanging metal fitting A is stably held without falling off the outer nose portion 1a.

次に、図5に示されるように、吊下金具Aとともに外側ノーズ部1aの先端を天井コンクリート等の表面Pの所定位置に当接させ、さらにピンaを打ち込むにあたって、釘打機を上方に押し込む。これにより、釘打機とともに内側ノーズ部1bが上方に移動してガイド軸部8に当たるが、ガイド片12の先端の外側傾斜部13に案内されて(図6参照)ガイド軸部8は内側ノーズ部1bの内側に挿入され、同時に案内羽根9も折り畳まれて内側ノーズ部1bの内側に納められる。   Next, as shown in FIG. 5, the tip of the outer nose portion 1 a is brought into contact with a predetermined position of the surface P such as ceiling concrete together with the hanging metal fitting A, and the nailing machine is moved upward when driving the pin a. Push in. As a result, the inner nose portion 1b moves upward together with the nail driver and hits the guide shaft portion 8, but is guided by the outer inclined portion 13 at the tip of the guide piece 12 (see FIG. 6). It is inserted inside the portion 1b, and at the same time, the guide vane 9 is folded and stored inside the inner nose portion 1b.

このように、ガイド部材7は案内羽根9の弾性反発力により安定して動かない状態に保持される。また、ガイド片12によりガイド軸部8の中心が位置決めされた状態に保持される。   In this way, the guide member 7 is held in a state where it does not move stably due to the elastic repulsive force of the guide vanes 9. Further, the guide piece 12 is held in a state where the center of the guide shaft portion 8 is positioned.

さらに、ガイド軸部8が長く、またガイド片12の先端を結んだ円O2の径は内側ノーズ部1bの内径よりもやや小さく形成されているので、図6に示されるように、内側ノーズ部1bがコンクリート等の表面に対して垂直でなく、やや傾いた状態で押し付けられていても、ガイド軸部8は垂直状態に保持される。   Further, since the guide shaft portion 8 is long and the diameter of the circle O2 connecting the tips of the guide pieces 12 is slightly smaller than the inner diameter of the inner nose portion 1b, as shown in FIG. Even if 1b is not perpendicular to the surface of concrete or the like but is pressed in a slightly inclined state, the guide shaft portion 8 is held in a vertical state.

そこで、釘打機を起動させると、内側ノーズ部1bからピンaが発射され、内側ノーズ部1bの先端のガイド部材7に当たる。ピンaは内側ノーズ部1b内を多少傾いて射出されることがあるが、ガイド部材7の中心にあるガイド穴10の先端には案内面11が形成されているので、ピンaの先端は案内面11に案内されてガイド軸部8のガイド穴10に飛び込み、このガイド穴10の内側を通過する。そして、吊下金具Aの固定片5の挿通孔4を通って天井コンクリート等の表面に垂直に打ち込まれる。ピンaの頭部は固定片5に残る。図7は吊下金具Aがピンaによって固定された状態を示す斜視図である。なお、上記吊下金具Aに留めつけられる対象物としては、電線ケーブル、ワッシャ、ダクト、冷媒管等がある。   Therefore, when the nailing machine is activated, the pin a is fired from the inner nose portion 1b and hits the guide member 7 at the tip of the inner nose portion 1b. The pin a may be ejected with a slight inclination inside the inner nose portion 1b. However, since the guide surface 11 is formed at the tip of the guide hole 10 at the center of the guide member 7, the tip of the pin a is guided. It is guided by the surface 11 and jumps into the guide hole 10 of the guide shaft portion 8 and passes through the inside of the guide hole 10. And it is driven perpendicularly to the surface of ceiling concrete or the like through the insertion hole 4 of the fixed piece 5 of the hanging metal fitting A. The head of the pin a remains on the fixed piece 5. FIG. 7 is a perspective view showing a state in which the hanging metal fitting A is fixed by the pin a. In addition, as an object fastened to the said hanging metal fitting A, there exist an electric wire cable, a washer, a duct, a refrigerant pipe, etc.

このように、垂直性が維持された状態で打ち込むことができるので、座屈、打ち損じ等が発生しにくい。   Thus, since it can drive in the state in which the perpendicularity is maintained, buckling, breakage and the like are unlikely to occur.

また、ピンaが打ち込まれたとき、ガイド軸部8の内面は広げられ、ガイド片12と案内羽根9も外側に押し広げられるが、打込み時の反動によって内側ノーズ部1bは天井コンクリート等の表面から離反するので、ガイド部材7の主たる部分は挿通孔4の外側に逃げて広がるから、ピンaの頭部の裏面と固定片5との間にガイド部材7は圧潰された部分を除いてほとんど残らない。したがって、ピンaの貫入量は十分に確保される。しかも、ガイド部材7のガイド軸部8自体は肉薄で、ガイド片12が補強している構造であるから、ガイド軸部8は垂直性の維持性能は高いが、外方への広がりに対する強度は小さいので、ガイド軸部8をピンaがガイド穴10を通るときの通過抵抗は非常に小さい。したがって、パワーロスが少なく、吊下金具Aを天井コンクリート等に強く固定することができる。   Further, when the pin a is driven, the inner surface of the guide shaft portion 8 is expanded and the guide piece 12 and the guide blade 9 are also pushed outward. Since the main part of the guide member 7 escapes to the outside of the insertion hole 4 and widens, the guide member 7 is almost between the back surface of the head of the pin a and the fixed piece 5 except for the crushed part. Does not remain. Therefore, the penetration amount of the pin a is sufficiently ensured. Moreover, since the guide shaft portion 8 itself of the guide member 7 is thin and the guide piece 12 is reinforced, the guide shaft portion 8 has a high perpendicularity maintaining performance, but the strength against the outward spread is high. Since it is small, the passage resistance when the pin a passes through the guide hole 10 through the guide shaft portion 8 is very small. Therefore, there is little power loss and the hanging metal fitting A can be strongly fixed to ceiling concrete etc.

なお、上記吊下金具Aはノーズ部がピンの打込み方向に摺動するタイプの釘打機にも適用することができる。その場合、ガイド部材7は図5および図6のような状態になる。この場合も、上記ガイド軸部8を釘打機のノーズ部に嵌め込んで吊下金具Aを下に向けたとき、案内羽根9が撓みながらその基部から曲がり、その先端がノーズ部の内面に斜めに係合するので、案内羽根9の弾性反発力と逆止作用とにより吊下金具Aはノーズ部に保持され、脱落することがない。吊下金具Aを上にして釘打機によりピンaをコンクリート等に打ち込む場合も、打ち込み作業が楽である。釘打機により打ち出されたピンaは案内羽根9によりノーズ部の中心に保持されたガイド軸部8を貫通してファスナーの挿通孔4を通ってコンクリート等に打ち込まれる。このとき、案内羽根9とガイド軸部8はファスナーの頭部によって外側に押し広げられ、圧潰されてピンaの頭部の外側に逃げる。したがって、打込みの障害になることがない。   The hanging metal fitting A can also be applied to a nailing machine in which the nose portion slides in the pin driving direction. In that case, the guide member 7 is in a state as shown in FIGS. Also in this case, when the guide shaft portion 8 is fitted in the nose portion of the nailing machine and the hanging metal fitting A is directed downward, the guide blade 9 bends from its base portion while being bent, and the tip thereof is on the inner surface of the nose portion. Since it engages diagonally, the hanging metal fitting A is held by the nose portion by the elastic repulsive force and the check action of the guide vanes 9 and does not fall off. Even when the pin a is driven into concrete or the like by a nailing machine with the hanging metal fitting A up, the driving operation is easy. The pin a driven out by the nailing machine passes through the guide shaft portion 8 held at the center of the nose portion by the guide blade 9 and is driven into concrete or the like through the insertion hole 4 of the fastener. At this time, the guide blade 9 and the guide shaft portion 8 are pushed outward by the head of the fastener, are crushed and escape to the outside of the head of the pin a. Therefore, there is no obstacle to driving.

また、案内羽根9とガイド片12はガイド軸部8の中心から放射状に形成されていればよく、その数に限定されない。例えば、図8のように案内羽根9とガイド片12をそれぞれ交互に4個設ける構成であってもよい。   Moreover, the guide blade 9 and the guide piece 12 should just be formed radially from the center of the guide shaft part 8, and are not limited to the number. For example, as shown in FIG. 8, a configuration in which four guide vanes 9 and four guide pieces 12 are alternately provided may be employed.

さらに、留付け具の実施形態としてZ字状吊下金具で説明したが、たとえば、サドルバンド金具やワッシャにガイド部材を取り付けた形状でもよく、また材質も金属製以外の樹脂製でもよい。   Furthermore, although the Z-shaped hanging metal fitting has been described as an embodiment of the fastener, for example, a shape in which a guide member is attached to a saddle band metal fitting or a washer may be used, and the material may be a resin other than a metal.

ところで、天井コンクリート等に固定された吊下金具Aは、引き抜き方向の力に対しては強固であるが、図7の矢印方向に力(荷重)Fが作用するとピンaを中心に回る可能性がある。図9(a)(b)(c)に示された吊下金具Aは、天井躯体Pに固定されたときに上記躯体Pに当接する面に複数の回り止め用突起5a、5bが形成されているものである。突起5a、5bはプレス加工等により簡単に形成することができる。   By the way, the hanging metal fitting A fixed to the ceiling concrete or the like is strong against the force in the pulling direction, but if the force (load) F acts in the direction of the arrow in FIG. There is. 9 (a), 9 (b), and 9 (c), a plurality of anti-rotation protrusions 5a and 5b are formed on the surface that comes into contact with the housing P when fixed to the ceiling housing P. It is what. The protrusions 5a and 5b can be easily formed by pressing or the like.

複数の突起5a、5bは、該金具Aのファスナー挿通孔4の近傍と、挿通孔4から十分に離れた位置の2箇所に設けられており、挿通孔4近傍の突起5aは3つであり、これら3つの突起5aの内の1つは吊下金具Aの長手方向中心線L上と中心線Lを挟んだ互いに対称的な位置に設けられている。   The plurality of protrusions 5a and 5b are provided at two locations in the vicinity of the fastener insertion hole 4 of the metal fitting A and at a position sufficiently away from the insertion hole 4, and there are three protrusions 5a in the vicinity of the insertion hole 4. One of these three protrusions 5a is provided on the longitudinal center line L of the hanging metal fitting A and at symmetrical positions with respect to the center line L.

なお、ここでは突起5aを3つ、突起5bを2つ設けたが、その個数は特に限定されるものではなく、それぞれ2〜4つ程度の突起を設け、周り止めとしての機能を保有するものであってもよい。   Here, three protrusions 5a and two protrusions 5b are provided. However, the number of protrusions 5a is not particularly limited, and two to four protrusions are provided, respectively, and have a function as a detent. It may be.

また、挿通孔4から十分に離れた位置の突起5bは2つであり、この2つの突起5bは中心線Lを挟んで互いに十分な間隔を存した対称的な位置でかつ吊下金具Aの段差部6のための屈曲部5e近傍に設けられている。   In addition, there are two protrusions 5b at a position sufficiently away from the insertion hole 4, and these two protrusions 5b are symmetrical positions with a sufficient distance from each other across the center line L, and It is provided in the vicinity of the bent portion 5 e for the step portion 6.

上記吊下金具Aも、図10のように、上述の吊下金具と同様にして、ファスナーaによって天井躯体Pに固定される。   As shown in FIG. 10, the hanging bracket A is also fixed to the ceiling casing P by a fastener a in the same manner as the above-described hanging bracket.

ところで、ファスナーaによって固定されたとき、ガイド部材7が潰されて裏側に回ったり(図11(a)参照)、躯体Pのコンクリート面に凹凸があったり、吊下金具Aの固定片5に反りがあったり(図11(b)参照)していると、固定片5の裏面が躯体P面に密着しない状態になることがある。しかし、吊下金具Aには天井躯体に固定されたときに上記躯体に当接する面には、複数の回り止め用突起5a、5bが形成されているから、図9(b)(c)に示すように、突起5a、5bが躯体Pに強く押し付けられるので、吊下金具Aは摩擦力により強固に保持され、ファスナーaを中心に回すように外力が加わっても、吊下金具Aは回らないので、作業者は吊下金具Aがしっかりと躯体Pに固定されているということが確信でき、信頼性が向上する。   By the way, when it is fixed by the fastener a, the guide member 7 is crushed and turned to the back side (see FIG. 11A), the concrete surface of the housing P has irregularities, or the fixing piece 5 of the hanging metal A If there is a warp (see FIG. 11B), the back surface of the fixed piece 5 may not be in close contact with the housing P surface. However, since a plurality of anti-rotation protrusions 5a and 5b are formed on the surface of the hanging metal fitting A that comes into contact with the housing when fixed to the ceiling housing, as shown in FIGS. 9B and 9C. As shown, since the projections 5a and 5b are strongly pressed against the housing P, the suspension fitting A is firmly held by the frictional force, and even if an external force is applied so as to turn around the fastener a, the suspension fitting A is not rotated. Therefore, the operator can be sure that the hanging metal fitting A is firmly fixed to the housing P, and the reliability is improved.

また、上記複数の突起は、挿通孔4の近傍に設けられた複数の突起5aと、挿通孔4から離れた位置に設けられた複数の突起5bとであるから、吊下金具Aはこれらの複数の突起5a、5bの互いの協働作用による摩擦力で強固に保持されるので、回り止め効果が高い。   In addition, the plurality of protrusions are a plurality of protrusions 5a provided in the vicinity of the insertion hole 4 and a plurality of protrusions 5b provided at positions away from the insertion hole 4, so Since the plurality of protrusions 5a and 5b are firmly held by the frictional force due to the mutual cooperative action, the anti-rotation effect is high.

さらに、ファスナー挿通孔4の近傍に設けられた複数の突起5aは回り止め効果は大きいが吊下金具Aが傾きやすい(図11(c)(d)参照)。これに対し、ファスナー挿通孔4から離れた位置に設けられた複数の突起5bは回り止め効果はそれほど大きくないが、吊下金具Aを安定に保持する効果が高い。したがって、これらの突起5a、5bのバランスの良い配置で、吊下金具Aの回り止めと傾きの防止を効果的に達成することができる。   Furthermore, although the plurality of protrusions 5a provided in the vicinity of the fastener insertion hole 4 have a large anti-rotation effect, the hanging metal fitting A is easily inclined (see FIGS. 11C and 11D). In contrast, the plurality of protrusions 5b provided at positions away from the fastener insertion holes 4 are not so effective in preventing rotation, but have a high effect of stably holding the hanging metal fitting A. Therefore, with the well-balanced arrangement of these protrusions 5a and 5b, the suspension metal fitting A can be effectively prevented from being rotated and tilted.

しかも、複数の突起5aと突起5bとを、上記ファスナー挿通孔4を挟んで互いに反対側に配置されているから、吊下金具Aの回り止めと傾きの防止をより一層効果的に実現することができる。   In addition, since the plurality of protrusions 5a and protrusions 5b are disposed on opposite sides of the fastener insertion hole 4, the suspension metal fitting A can be prevented from rotating and tilted more effectively. Can do.

なお、留付け具を固定する被打ち込み材としての建物躯体は天井躯体に限定されない。壁躯体や床躯体であってもよい。また、ファスナーは釘に限らず、ネジでもあってもよい。   In addition, the building frame as the driven material for fixing the fastening tool is not limited to the ceiling frame. It may be a wall frame or a floor frame. Further, the fastener is not limited to a nail but may be a screw.
