Description

本考案は、建設現場などで鋼材と鋼材を接続する際に接続部材として用いられるナットが固着された鋼材に関する。さらに詳しくは、ナットに設けられた接合部を介して鋼材にナットが固着されてなるナットが固着された鋼材であって、接合部が、鋼材に設けられた開口部に嵌入され、平面視で開口部の中心から離れる方向に圧接されてなるナットが固着された鋼材に関する。   The present invention relates to a steel material to which a nut used as a connecting member is fixed when the steel material is connected at a construction site or the like. More specifically, the steel material has a nut fixed to a steel material through a joint portion provided on the nut, and the joint portion is fitted into an opening provided in the steel material, and is viewed in plan view. The present invention relates to a steel material to which a nut pressed in a direction away from the center of the opening is fixed.

従来より、建設用の鉄骨などを接続するために、接続部材としてナットを固着した鋼材が用いられている。   Conventionally, in order to connect a construction steel frame or the like, a steel material to which a nut is fixed as a connecting member has been used.

また、特許文献１には、溶接しようとするナットを簡便かつ確実に鋼材の円形孔の中心に合わせて仮止め固定する治具を提案しており、その中で、一対のハンドルを握り締めるだけでナットを溶接する位置を決めて、確実にナットを鋼材に仮止め固定する。これにより、ナットを鋼材へ溶接する作業が効率よく施される、という技術である。   Patent Document 1 proposes a jig that temporarily and securely fixes a nut to be welded to a center of a circular hole in a steel material, and only a pair of handles are squeezed. Decide the position to weld the nut and securely fix the nut to the steel. Thereby, it is the technique that the operation | work which welds a nut to steel materials is performed efficiently.

このように、ナットを鋼材に固着させる場合には、溶接により固着させるということが前提となっていた。   As described above, when the nut is fixed to the steel material, it is assumed that the nut is fixed by welding.

特開平８−５７７７２号公報JP-A-8-57772

上述した従来の技術では、建設現場において、溶接によりナットを鋼材に固着していた。そのため、鉄骨の形状や、作業現場の状況により、作業者の手の届かない位置に接合部材が設けられている場合には、ナットを熔接固着させてから接続部材を接続位置に配置する必要があり、ナットを固着する作業が厄介である。さらに、ナットはメッキ具の上に溶接されるため、後にサラエルと称する工程（すなわちナットのねじ山に熔接時に溶接カスが付着した場合にねじ山を修正する工程）が必要になる。   In the conventional technique described above, the nut is fixed to the steel material by welding at the construction site. Therefore, when the joining member is provided at a position that is out of the reach of the worker due to the shape of the steel frame or the situation at the work site, it is necessary to place the connecting member at the connecting position after the nut is welded and fixed. The work of fixing the nut is troublesome. Further, since the nut is welded onto the plating tool, a step called Sarael later (that is, a step of correcting the screw thread when welding residue adheres to the screw thread of the nut) is required.

すなわち、従来の技術では、溶接によりナットを固着する場合には、作業工数が多く、それに伴いコストが高くなってしまうという問題がある。   In other words, the conventional technique has a problem that, when the nut is fixed by welding, the number of work steps is large, and the cost increases accordingly.

本考案は、上記従来の問題に鑑み、鋼材にナットを接合する際に溶接作業を施すことなく、ナットと鋼材を一体化し、現場での作業工数を削減することができ、ひいてはコスト低減を実現するナットが固着された鋼材を提供することを目的とするものである。   In view of the above-described conventional problems, the present invention integrates the nut and the steel material without performing welding work when joining the nut to the steel material, and can reduce the work man-hours at the site, thereby realizing cost reduction. An object of the present invention is to provide a steel material to which a nut to be fixed is fixed.

本考案のナットが固着された鋼材は、接合部を備えたナットが該接合部を介して固着された鋼材であって、
前記接合部が鋼材に穿設された開口部に嵌入され、かつ当該開口部の半径方向に圧接されてなる
ことを特徴としている。 The steel material to which the nut of the present invention is fixed is a steel material to which a nut provided with a joint is fixed via the joint,
The joining portion is fitted into an opening formed in the steel material and is pressed in the radial direction of the opening.

また、前記接合部は前記ナットの軸心方向に平行に延びる筒状を呈していることが好ましい。   Moreover, it is preferable that the said junction part is exhibiting the cylinder shape extended in parallel with the axial center direction of the said nut.

また、前記開口部の周縁にテーパが形成されていることが好ましい。   Further, it is preferable that a taper is formed on the periphery of the opening.

また、前記開口部の周縁には複数の溝が放射状に設けられていることが好ましい。   Moreover, it is preferable that a plurality of grooves are provided radially on the periphery of the opening.

本考案のナットが固着された鋼材によれば、本考案のナットが固着された鋼材は工場で製造することができ、ナットに設けられた接合部を鋼材に圧接することにより、ナットが鋼材に固着されているので、現場で鋼材にナットを溶接接合する必要がない。これにより、現場での作業工数を削減することができ、建設コストの削減を図ることができる。また、本考案のナットが固着された鋼材は現場ではなく工場で製造することができるので、ナットの材質、形状を適宜変更することによりナットを所望の強度で固着することができる。   According to the steel material to which the nut of the present invention is fixed, the steel material to which the nut of the present invention is fixed can be manufactured at a factory, and the nut is made into the steel material by pressing the joint portion provided on the nut to the steel material. Since it is fixed, it is not necessary to weld and join the nut to the steel material in the field. Thereby, the work man-hour at the field can be reduced and the construction cost can be reduced. Further, since the steel material to which the nut of the present invention is fixed can be manufactured not at the site but at the factory, the nut can be fixed at a desired strength by appropriately changing the material and shape of the nut.

本考案のナットが固着された鋼材はナットに設けられた接合部を介して鋼材にナットが固着されてなるナットが固着された鋼材であって、接合部が、鋼材に設けられた開口部に嵌入され、平面視で開口部の中心から離れる方向に圧接されている。   The steel material to which the nut of the present invention is fixed is a steel material to which a nut is fixed to a steel material through a joint portion provided on the nut, and the joint portion is in an opening provided in the steel material. It is inserted and pressed in a direction away from the center of the opening in plan view.

以下で図面を用いて本考案のナットが固着された鋼材について詳細に説明する。   Hereinafter, the steel material to which the nut of the present invention is fixed will be described in detail with reference to the drawings.

実施の形態１
図１および図２において、ナットが固着された鋼材１はコの字型の鋼材２とナット３とから構成される。鋼材２には、ボルトを貫通させるための円形孔の開口部２１が設けられている。また、図４（ｆ）に示すようにナット３には接合部３ａがナット３の軸心方向に平行に、かつ、少なくともナット３の一端面側から突設するように設けられ、鋼材に形成された開口部２１の側面に内接するように設けられている。すなわち、接合部３ａはナット３の少なくとも一端面側から延びる筒状の形状である。この接合部３ａは鋼材２の開口部２１に嵌入され、さらに、接合部３ａが開口部２１の中心から離れる方向に圧接されることにより、ナット３を鋼材２に固着する。 Embodiment 1
1 and 2, a steel material 1 to which a nut is fixed is composed of a U-shaped steel material 2 and a nut 3. The steel material 2 is provided with an opening 21 of a circular hole for allowing the bolt to pass therethrough. As shown in FIG. 4 (f), the joint 3a is provided on the nut 3 so as to protrude in parallel with the axial direction of the nut 3 and at least from one end surface side of the nut 3, and is formed on the steel material. The opening 21 is provided so as to be inscribed in the side surface. That is, the joint portion 3 a has a cylindrical shape extending from at least one end face side of the nut 3. The joint 3 a is fitted into the opening 21 of the steel 2, and the joint 3 a is pressed in a direction away from the center of the opening 21, thereby fixing the nut 3 to the steel 2.

また、開口部２１には図４（ｅ）に示すように、接合部３ａを圧接するためのテーパ部２ａと、ナット３の共回りを防ぐための円弧状の溝２ｂが４箇所に形成されている。このテーパ部２ａは、鋼材２において開口部２１を形成している部分の縦断面に形成され、ボルトの頭が接する面に向かって広がるように形成されたテーパ状の部分である。すなわち、鋼材２において、開口部２１の周縁にテーパが形成されている。   Further, as shown in FIG. 4E, the opening 21 is formed with four tapered portions 2a for press-contacting the joint portion 3a and arc-shaped grooves 2b for preventing the nut 3 from rotating together. ing. This taper part 2a is a taper-shaped part formed in the longitudinal cross-section of the part which forms the opening part 21 in the steel material 2, and was formed so that it might spread toward the surface which a bolt head contacts. That is, in the steel material 2, a taper is formed on the periphery of the opening 21.

また、共回りを防ぐための溝２ｂについて説明すると、開口部２１の周縁には複数の溝２ｂが放射状に設けられている。すなわち、テーパ部２ａに複数の溝２ｂが平面視で開口部の中心から離れる方向に設けられ、接合部３ａを圧接した際に、この溝２ｂに接合部３ａが食い込む。よって、ボルトを締め付ける際に、接合部３ａが溝２ｂに引っかかることで、ボルトの回転と共にナット３が回転するのを防ぐことができる。   The groove 2b for preventing co-rotation will be described. A plurality of grooves 2b are provided radially on the periphery of the opening 21. That is, the plurality of grooves 2b are provided in the taper portion 2a in a direction away from the center of the opening in a plan view, and when the joint portion 3a is pressed, the joint portion 3a bites into the groove 2b. Therefore, when the bolt is tightened, the joint 3a is caught in the groove 2b, so that the nut 3 can be prevented from rotating together with the rotation of the bolt.

上記構成により、以下で本考案のナットが固着された鋼材１の製造方法について図面を用いて説明する。   A method for manufacturing the steel material 1 to which the nut of the present invention is fixed will be described below with reference to the drawings.

まず、図４（ａ）に示すような断面を有する鋼材２に特殊形状のパンチを用いてプレスすることにより開口部２１を形成する。   First, the opening 21 is formed by pressing a steel material 2 having a cross section as shown in FIG.

つぎに、接合部３ａが圧接される部分であるテーパ部２ａおよびナットの供回りを防止するための溝２ｂを形成するため、図４（ｃ）に示すようなテーパ部形成用型４を用いてプレス加工する。テーパ部形成用型４の形状は、円とこの円の４方向に円弧状の突出部４ａを有した底面を有する錐体を底面に平行な面で切断した形状である。このテーパ部２ａおよび溝２ｂを形成するためのプレス工程を図４（ｄ）に示している。このようにして形成された開口部２１、テーパ部２ａおよび溝２ｂを図４（ｅ）に示す。   Next, in order to form the taper portion 2a, which is a portion to which the joint portion 3a is pressure-contacted, and the groove 2b for preventing the rotation of the nut, a taper portion forming die 4 as shown in FIG. 4C is used. Press. The shape of the taper portion forming die 4 is a shape obtained by cutting a cone and a cone having a bottom surface having arcuate protrusions 4a in the four directions of the circle along a plane parallel to the bottom surface. FIG. 4D shows a pressing process for forming the tapered portion 2a and the groove 2b. FIG. 4E shows the opening 21, the tapered portion 2a, and the groove 2b formed in this way.

つぎに、図４（ｆ）に示すように、鋼材２に形成された開口部２１にナット３の接合部３ａを嵌入する。ナット３の接合部３ａが鋼材２の開口部２１に嵌入された状態の図を図４（ｇ）に示す。   Next, as shown in FIG. 4 (f), the joint 3 a of the nut 3 is fitted into the opening 21 formed in the steel material 2. FIG. 4 (g) shows a state in which the joint 3 a of the nut 3 is fitted into the opening 21 of the steel material 2.

つぎに、接合部３ａを開口部２１の中心から離れるようにパンチを用いて加圧する。このパンチの形状は、円錐面と円錐の底面に平行な２面からなる立体である（図示せず）。このようにして、接合部３ａを鋼材２に形成されたテーパ部２ａおよび溝２ｂに圧接する。図４（ｈ）に接合部３ａを鋼材２に圧接した状態のナット３を示す。   Next, the joint 3a is pressurized with a punch so as to be away from the center of the opening 21. The punch has a solid shape (not shown) composed of two surfaces parallel to the conical surface and the bottom surface of the cone. In this way, the joint 3a is pressed against the tapered portion 2a and the groove 2b formed in the steel material 2. FIG. 4 (h) shows the nut 3 in a state in which the joint 3 a is pressed against the steel material 2.

本考案のナットが固着された鋼材１は上述したような工程を経て工場で製造され、現場に運んで使用される。   The steel material 1 to which the nut of the present invention is fixed is manufactured in a factory through the processes described above, and is carried to the site for use.

ここで、本考案のナットが固着された鋼材１を鉄骨の接続に用いた場合について図５（ａ）、図５（ｂ）および図６を用いて説明する。これらの図に示すように、本考案のナットが固着された鋼材１は接続部材として機能し、鉄骨５ａと鉄骨５ｂとをボルト６を介して接続する。鉄骨の形状がコの字状や複雑な形状で、施工の際に作業者の手が届きにくい位置に接合部材を設けける場合であっても、接合部材として本考案のナットが固着された鋼材１を用いればナットを溶接する作業が不要であるので、現場での工数削減につながる。   Here, the case where the steel material 1 to which the nut of the present invention is fixed is used for the connection of the steel frame will be described with reference to FIGS. 5 (a), 5 (b) and 6. FIG. As shown in these drawings, the steel material 1 to which the nut of the present invention is fixed functions as a connecting member, and connects the steel frame 5 a and the steel frame 5 b via bolts 6. Even if the steel member has a U-shape or a complicated shape, and the joint member can be installed at a position that is difficult for the operator to reach during construction, the steel material to which the nut of the present invention is fixed as the joint member If 1 is used, the work of welding the nut is unnecessary, leading to a reduction in the number of man-hours on site.

以上により、本考案のナットが固着された鋼材１は、工場で製造され、ナット３に設けられた接合部３ａを介して鋼材２にナット３が固着されてなるナットが固着された鋼材１であって、接合部３ａが、鋼材２に設けられた開口部２１に嵌入され、平面視で開口部２１の中心から離れる方向に圧接されているので現場で鋼材２にナット３を溶接接合する必要がない。これによりナットと鋼材が既に一体化されているので、現場での作業工数を削減することができ、建設コストの削減を図ることができる。また、本考案のナットが固着された鋼材１は現場ではなく工場で製造することができるので、ナットの材質、形状を適宜変更することによりナットを所望の強度で固着することができる。   As described above, the steel material 1 to which the nut of the present invention is fixed is manufactured in a factory, and the steel material 1 to which the nut 3 is fixed to the steel material 2 through the joint portion 3a provided on the nut 3 is fixed. In addition, since the joining portion 3a is inserted into the opening 21 provided in the steel material 2 and is pressed in a direction away from the center of the opening 21 in plan view, the nut 3 needs to be welded to the steel material 2 at the site. There is no. As a result, since the nut and the steel material are already integrated, the number of work steps at the site can be reduced, and the construction cost can be reduced. Moreover, since the steel material 1 to which the nut of the present invention is fixed can be manufactured not at the site but at the factory, the nut can be fixed at a desired strength by appropriately changing the material and shape of the nut.

なお、本実施の形態では、コの字型のナットが固着された鋼材１について説明したが、これに限らず本考案のナットが固着された鋼材１は板状であってもよい。   In addition, although this Embodiment demonstrated the steel material 1 to which the U-shaped nut was fixed, not only this but the steel material 1 to which the nut of this invention was fixed may be plate shape.

さらに、本実施の形態では、ナットが固着された鋼材１に２つのナット３が１列に並んで取り付けられている場合について説明したが、これに限らず、本考案のナットが固着された鋼材１には複数のナット３が複数列で並んで取り付けられていてもよい。   Furthermore, in this Embodiment, although the case where the two nuts 3 were attached to the steel material 1 to which the nut was fixed in a line was demonstrated, it is not restricted to this, The steel material to which the nut of this invention was fixed 1, a plurality of nuts 3 may be attached in a plurality of rows.

さらに、本実施の形態では、ナット３の共回りを防止するための溝２ｂを一つの開口部２１に４箇所形成する場合について説明したが、これに限らず、ナット３の共回りを防止するための溝２ｂは一つの開口部２１に複数個所形成されていればよい。   Furthermore, in this Embodiment, although the case where the groove | channel 2b for preventing co-rotation of the nut 3 was formed in four places in one opening part 21 was demonstrated, not only this but the co-rotation of the nut 3 is prevented. For this purpose, a plurality of grooves 2 b may be formed in one opening 21.

さらに、本実施の形態では、ナット３の一方の側の端面から接合部３ａが突設している場合について説明したが、これに限らず、接合部３ａはナット３の両方の側の端面から突設していてもよい。   Further, in the present embodiment, the case where the joint portion 3a protrudes from the end surface on one side of the nut 3 has been described. You may project.
