Description
この発明は建設工事における給排水、空調、電気等の設備工事に際して、溝形鋼に配管、設備機器等を吊持するための吊ボルトを固定する固定金具に関する。 The present invention relates to a fixing bracket for fixing a suspension bolt for suspending piping, facility equipment and the like to a grooved steel in construction work such as water supply / drainage, air conditioning, and electricity in construction work.
従来、この種の固定金具として、図14及び図15に示すように、適宜厚さの平鋼板を一方は溝形鋼の開口部幅より短く、他方は長くなるような四辺形状に形成し、且つ、ほぼ中央にネジ孔を設けた固定金具が開示されており、その使用方法として、吊ボルトの先端を固定金具のネジ孔に螺着させると共に、他端を手で持って、溝形鋼の開口より固定金具を挿入、回転させることで、固定金具の長辺側が溝形鋼の両側辺の内側に当接した後、吊ボルトの先端が溝形鋼の上辺の下面に当接する一方で、固定金具の下面が溝形鋼の開口両端縁に当接した状態となりその2点間の張力により固定していた。 Conventionally, as shown in FIGS. 14 and 15, as a fixing metal of this type, a flat steel plate having an appropriate thickness is formed in a quadrilateral shape such that one is shorter than the opening width of the groove steel and the other is longer, In addition, a fixing bracket having a screw hole at the center is disclosed. As a method of using the fixing bracket, the tip of the suspension bolt is screwed into the screw hole of the fixing bracket, and the other end is held by hand. By inserting and rotating the fixing bracket from the opening, the long side of the fixing bracket contacts the inside of both sides of the channel steel, and then the end of the suspension bolt contacts the lower surface of the upper side of the channel steel. The lower surface of the fixture was brought into contact with both end edges of the grooved steel and was fixed by the tension between the two points.
しかし、上記従来の固定金具では、吊ボルトを固定金具のネジ孔に螺合し、溝形鋼の開口内に挿入した後、吊ボルトを先端が溝形鋼の上辺の下面に当接するまで回転させる必要があり、吊ボルトを回転させる作業に時間と手間を浪費していた。
また、吊ボルトの先端は必ずしも平坦でなく、例えば、作業現場において、適宜長さに切断したものを使用することも多々あるので、溝形鋼の上辺の下面に当接する際、吊ボルトの先端の全面が当接していない場合があり、安定性がなくなり、固定力の確実性に欠けるなどの問題点があった。
However, in the above-described conventional fixing bracket, after the suspension bolt is screwed into the screw hole of the fixing bracket and inserted into the opening of the grooved steel, the suspension bolt is rotated until the tip contacts the lower surface of the upper side of the grooved steel. Therefore, time and labor were wasted on the work of rotating the suspension bolt.
Also, the tip of the suspension bolt is not necessarily flat. For example, in many cases, the suspension bolt is cut to an appropriate length at the work site. Therefore, when contacting the lower surface of the upper side of the channel steel, the tip of the suspension bolt is used. In some cases, the entire surface of the film does not come into contact with each other, resulting in problems such as lack of stability and lack of certainty of fixing force.
この発明は上記従来の課題に鑑みなされたもので、その目的は、吊ボルト固定金具を溝形鋼に固定する際、吊ボルトを回転させる締込み作業を削減すると共に、溝形鋼の上辺と開口端縁に安定して当接することで固定力の確実性に優れた吊ボルト固定金具を提供することにある。 The present invention has been made in view of the above-described conventional problems. The purpose of the present invention is to reduce the tightening work of rotating the suspension bolt when the suspension bolt fixing bracket is fixed to the groove steel, and the upper side of the groove steel. An object of the present invention is to provide a suspension bolt fixing bracket which is excellent in fixing force reliability by stably contacting an opening edge.
その手段として、本発明の請求項1は溝形鋼の開口部より挿入し、ほぼ90°回転させることで長手側の対辺が該溝形鋼の両側辺の内側に当接する四辺形状の水平支持片のほぼ中央に吊ボルトを取付けるネジ孔を設けると共に、長手側の少なくとも一端を上方に折曲げて側片を形成し、該側片の端部にV字型の屈曲片を底部が該ネジ孔のほぼ軸芯上に配置するように一体的に形成して、前記ネジ孔に螺通させる吊ボルトが前記屈曲片の底部を押し上げて該屈曲片の先端を前記溝形鋼の上辺の下面に当接させて固定することを特徴とする。 As a means for this, claim 1 of the present invention is a horizontal support having a quadrilateral shape in which the opposite side on the long side is in contact with the inside of both sides of the channel steel by inserting it through the opening of the channel steel and rotating it approximately 90 °. A screw hole for attaching a suspension bolt is provided in the approximate center of the piece, and at least one end of the longitudinal side is bent upward to form a side piece, and a V-shaped bent piece is formed at the end of the side piece and the bottom is the screw. A suspension bolt that is integrally formed so as to be disposed substantially on the axial center of the hole and is screwed into the screw hole pushes up the bottom of the bent piece so that the tip of the bent piece is the lower surface of the upper side of the channel steel It is made to contact | abut and to fix .
本発明の請求項2は前記水平支持片の長手側の両端をそれぞれ上方に折曲げて側片を形成し、該側片の端部にV字型の屈曲片を底部が該ネジ孔のほぼ軸芯上に配置するように一体的に形成したことを特徴とする。 According to a second aspect of the present invention, both ends of the horizontal support piece on the longitudinal side are bent upward to form a side piece, a V-shaped bent piece is formed at the end of the side piece, and the bottom is substantially the screw hole. It is formed integrally so as to be disposed on the shaft core.
本発明の請求項3は前記水平支持片に溝形鋼の開口両端縁に掛止する掛止部を一体的に形成したことを特徴とする。 A third aspect of the present invention is characterized in that the horizontal support piece is integrally formed with a latching portion that latches at both ends of the opening of the channel steel.
本発明の請求項1は、溝形鋼の開口部より挿入し、ほぼ90°回転させることで長手側の対辺が該溝形鋼の両側辺の内側に当接する四辺形状の水平支持片のほぼ中央に吊ボルトを取付けるネジ孔を設けると共に、長手側の少なくとも一端を上方に折曲げて側片を形成し、該側片の端部にV字型の屈曲片を底部が該ネジ孔のほぼ軸芯上に配置するように一体的に形成したことにより、水平支持片のネジ孔に吊ボルトの先端を螺合し、溝形鋼の開口部より挿入し、ほぼ90°回転させることで長手側の対辺が該溝形鋼の両側辺の内側に当接する。
更に吊ボルトを回転することで、その先端がネジ孔を螺通して、ネジ孔のほぼ軸芯上に配置したV字型の屈曲片の底部を押し上げて、屈曲片の先端が溝形鋼の上辺の下面に当接すると共に、水平支持片は開口両端縁に当接した状態となり、その2点間の張力により固定ことができる。
すなわち、ほぼ屈曲片の片辺の長さ分だけ吊ボルトを締込む必要がなくなり、その分、吊ボルトを回転させる作業も削減することができる。
According to claim 1 of the present invention, the horizontal support piece having a quadrilateral shape in which the opposite side of the longitudinal side is in contact with the inside of both sides of the grooved steel by being inserted through the opening of the grooved steel and rotated approximately 90 ° A screw hole for attaching a suspension bolt is provided at the center, and at least one end of the longitudinal side is bent upward to form a side piece, and a V-shaped bent piece is formed at the end of the side piece, and the bottom is approximately the screw hole. By integrally forming so as to be placed on the shaft core, the end of the suspension bolt is screwed into the screw hole of the horizontal support piece, inserted through the opening of the channel steel, and rotated approximately 90 ° to make it longer The opposite side of the side abuts on the inner side of both sides of the channel steel.
Further, by rotating the suspension bolt, the tip of the screw is threaded through the screw hole, and the bottom of the V-shaped bent piece arranged almost on the axial center of the screw hole is pushed up. While being in contact with the lower surface of the upper side, the horizontal support piece is in contact with both edges of the opening and can be fixed by the tension between the two points.
That is, it is not necessary to tighten the suspension bolt substantially by the length of one side of the bent piece, and the work for rotating the suspension bolt can be reduced accordingly.
また、屈曲片の先端の幅全面が溝形鋼の上辺の下面に当接するので安定し、確実な固定力を得ることができる。 In addition, since the entire width of the tip of the bent piece contacts the lower surface of the upper side of the channel steel, the bending piece is stable and a reliable fixing force can be obtained.
本発明の請求項2は、前記水平支持片の長手側の両端をそれぞれ上方に折曲げて側片を形成し、該側片の端部にV字型の屈曲片を底部が該ネジ孔のほぼ軸芯上に配置するようにそれぞれ一体的に形成したことにより、吊ボルトの軸力を左右一対の屈曲片が均等して受け、溝形鋼の上辺の下面に伝えることで安定した張力を得ることができるので、確実な固定力を得ることができる。 According to a second aspect of the present invention, both ends of the horizontal support piece on the longitudinal side are bent upward to form side pieces, a V-shaped bent piece is formed at the end of the side piece, and the bottom portion of the screw hole is formed. By integrally forming them so as to be arranged almost on the shaft core, the pair of left and right bent pieces receive the axial force of the suspension bolts evenly and transmit them to the lower surface of the upper side of the channel steel, so that a stable tension can be obtained. Since it can be obtained, a certain fixing force can be obtained.
本発明の請求項3は、前記水平支持片に溝形鋼の開口両端縁に掛止する掛止部を一体的に形成したことにより、吊ボルトの締込みにより水平支持片が開口両端縁にある程度の張力により当接した時から、掛止部が開口両端縁に掛止し、拘束させるので、左右のすべりが抑えられ、安定して固定することができる。 According to a third aspect of the present invention, the horizontal support piece is integrally formed on the both ends of the opening of the grooved steel on the horizontal support piece. Since the latching portion is latched and restrained at both edges of the opening from the time when they are brought into contact with a certain amount of tension, the left and right slip can be suppressed, and can be stably fixed.
以上のように本発明の溝形鋼用吊ボルト固定金具は構成されているので、屈曲片の片辺の長さ分だけ吊ボルトを締込む必要がなくなり、その分、吊ボルトを回転させる作業も削減することができるので、取付け時間が短く、作業効率の向上を図ることができると共に、安定した張力を得ることで確実な固定力を得ることができるので取付け作業の信頼性が向上する。 As described above, the grooved steel suspension bolt fixing bracket of the present invention is configured, so it is not necessary to tighten the suspension bolt by the length of one side of the bent piece, and the work of rotating the suspension bolt by that amount. Therefore, the mounting time is short, the work efficiency can be improved, and a reliable fixing force can be obtained by obtaining a stable tension, thereby improving the reliability of the mounting work.
また、開口両端縁に左右のすべりなく、安定して固定することができるので、確実な固定力を得ることができ、更に取付け作業の信頼性が向上する。 In addition, since it can be stably fixed without sliding left and right at both ends of the opening, a reliable fixing force can be obtained, and the reliability of the mounting operation is further improved.
