Description

本発明はＨ型鋼、Ｉ型鋼といった金属材を溶接、ボルトーナット締め等により連結するのに使用される連結金具に関する。 The present invention relates to connecting metal fittings used for connecting metal materials such as H-shaped steel and I-shaped steel by welding, bolt-nut tightening, and the like.

ビル、建物、橋梁といった構造物は、Ｈ型鋼、Ｉ型鋼といった金属材を溶接、ボルトーナット締め等により連結して構築されている。この場合、側面視Ｌ字形の連結金具が使用されている。連結金具の一例として特許文献1、２の連結金具がある。 Structures such as buildings, buildings, and bridges are constructed by connecting metal materials such as H-shaped steel and I-shaped steel by welding, bolt-nut tightening, and the like. In this case, an L-shaped connecting metal fitting is used. As an example of the connecting metal fitting, there are the connecting metal fittings of Patent Documents 1 and 2.

特許文献１、２のいずれの連結金具も底板と縦板がＬ形になっている。この連結金具を使用して二つの金属材を連結する場合、連結金具の底板を一方の金属材の上に載せて溶接し、縦板に他方の金属材を宛がい、縦板のボルト孔と金属材のボルト孔にボルトを挿入し、そのボルトにナットを螺合して締め付けることにより両金属材を連結する。 The bottom plate and the vertical plate of both the connecting metal fittings of Patent Documents 1 and 2 are L-shaped. When connecting two metal materials using this connecting metal fitting, the bottom plate of the connecting metal fitting is placed on one metal material and welded, and the other metal material is addressed to the vertical plate, and the bolt holes of the vertical plate are used. A bolt is inserted into a bolt hole of a metal material, and a nut is screwed into the bolt and tightened to connect the two metal materials.

特許文献１の連結金具はＬ字状に曲げた屈曲部の外面が湾曲しているため、底片が縦片よりも短く形成されると重心位置が高くなって、金属材の上に載せた連結金具が倒れ易くなり、溶接しにくくなる。 Since the outer surface of the bent portion of the connecting metal fitting of Patent Document 1 is curved in an L shape, if the bottom piece is formed shorter than the vertical piece, the position of the center of gravity becomes higher and the connecting metal material is placed on the metal material. The metal fittings tend to fall over, making it difficult to weld.

特許文献２の連結金具は縦板の幅方向中間位置に小突片があるため、金属材の上に載せた場合、特許文献１の連結金具よりは倒れにくくなり、安定性があるが、屈曲部の外面が湾曲しているため、底片が縦片よりも短く形成されると重心位置が高くなって、金属材の上に載せた連結金具が倒れ易くなり、溶接しにくくなる。 Since the connecting metal fitting of Patent Document 2 has a small protrusion at an intermediate position in the width direction of the vertical plate, when it is placed on a metal material, it is less likely to fall down than the connecting metal fitting of Patent Document 1, and it is stable but bent. Since the outer surface of the portion is curved, if the bottom piece is formed shorter than the vertical piece, the position of the center of gravity becomes high, and the connecting metal fitting placed on the metal material tends to fall down, making it difficult to weld.

本発明は、金属材の上に載せても倒れにくく安定し、金属材の所定位置に位置決めし易い連結金具を提供することを目的とする。 An object of the present invention is to provide a connecting metal fitting that is stable even when placed on a metal material and is easily positioned at a predetermined position of the metal material.

本発明の連結金具は、底板と縦板がＬ字状である連結金具において、底板と縦板の曲げ箇所の幅方向両端側に空間部があり、底板の幅方向両端側であって前記空間部よりも外側に支持片があり、支持片が縦板の背面側に突出しているものである。底板と縦板の双方又はいずれか一方に位置合わせ用の目印が表示されている。 The connecting metal fitting of the present invention is a connecting metal fitting in which the bottom plate and the vertical plate are L-shaped, and has spaces on both ends in the width direction of the bent portion of the bottom plate and the vertical plate, and the space on both ends in the width direction of the bottom plate. There is a support piece on the outside of the portion, and the support piece projects to the back side of the vertical plate. Alignment marks are displayed on both the bottom plate and / or the vertical plate.

本発明の連結金具は次のような効果がある。
（１）底板と縦板の曲げ箇所の幅方向両端側に空間部を設けて、底板と縦板を直角に曲げてあるため、底板を金属材の上に載せたときに垂直に立ち易く、倒れにくく、底板と金属材との連結が容易になる。
（２）底板の幅方向両側に支持片があり、支持片が縦板の背面側に突出しているので、底板を金属材の上に載せたときに垂直に立ち易く、倒れにくく、底板と金属材との連結が容易になる。
（３）底板と縦板の双方又はいずれか一方に位置合わせ用の目印が表示されているので、金属材の上に載せる底板を、金属材に表示されているケガキ線に位置合わせし易い。 The connecting metal fitting of the present invention has the following effects.
(1) Since spaces are provided on both ends of the bent portion of the bottom plate and the vertical plate in the width direction and the bottom plate and the vertical plate are bent at right angles, it is easy to stand vertically when the bottom plate is placed on a metal material. It does not easily fall over and makes it easy to connect the bottom plate to the metal material.
(2) Since there are support pieces on both sides of the bottom plate in the width direction and the support pieces project to the back side of the vertical plate, it is easy to stand vertically when the bottom plate is placed on a metal material, it is hard to fall down, and the bottom plate and metal. Easy to connect with the material.
(3) Since the alignment mark is displayed on both or one of the bottom plate and the vertical plate, it is easy to align the bottom plate placed on the metal material with the marking line displayed on the metal material.

（連結金具の実施形態）
本発明の連結金具の一例を、図１（ａ）（ｂ）を参照して説明する。図示した連結金具１は一枚の金属板を側面視Ｌ字状に折り曲げて底板２と縦板３としてある。連結金具１は折り曲げる前に、折り曲げ部４の幅方向両端側を打ち抜くとか切欠くなどして空間部５を設け、その後に、折り曲げ部４から折り曲げてある。空間部５があるため、折り曲げ部４が直角に曲がり、縦板３が底板２に対して垂直に立ち上がるようにしてある。 (Embodiment of connecting metal fittings)
An example of the connecting metal fitting of the present invention will be described with reference to FIGS. 1 (a) and 1 (b). The illustrated connecting metal fitting 1 is formed as a bottom plate 2 and a vertical plate 3 by bending one metal plate into an L shape in a side view. Before bending, the connecting metal fitting 1 is provided with a space portion 5 by punching or notching both ends in the width direction of the bent portion 4, and then bent from the bent portion 4. Since there is a space portion 5, the bent portion 4 is bent at a right angle, and the vertical plate 3 stands up perpendicular to the bottom plate 2.

底板２の幅方向両端には支持片６がある。支持片６は前記空間部５を形成するときに空間部５の外側に残し、縦板３を折り曲げることにより底板２の幅方向両端縦板側に突出している。支持片６の横幅及び長さは空間部５の横幅及び長さにより異なるが、図示した実施形態では、支持片６の先端部６ａが縦板３の背面３ａと面一になるようにしてある。面一とすることにより、同じ形状の連結金具１の縦板３の背面に他の縦板を重ね易くなる。 Support pieces 6 are provided at both ends of the bottom plate 2 in the width direction. The support piece 6 is left outside the space portion 5 when the space portion 5 is formed, and is projected toward both ends of the bottom plate 2 in the width direction by bending the vertical plate 3. The width and length of the support piece 6 differ depending on the width and length of the space portion 5, but in the illustrated embodiment, the tip portion 6a of the support piece 6 is flush with the back surface 3a of the vertical plate 3. .. By making them flush with each other, it becomes easy to stack another vertical plate on the back surface of the vertical plate 3 of the connecting metal fitting 1 having the same shape.

縦板３には二つの止め穴７が開口されている。図示した止め穴７は上下に一直線上に二個設けてあるが、止め穴７は横並びに二個設けることもできる。必要に応じて、一個或いは三個以上であってもよく、大きさも必要に応じて決定できる。底板２にも開口しておくことができる。 Two stop holes 7 are opened in the vertical plate 3. Although the illustrated stop holes 7 are provided vertically in a straight line, two stop holes 7 may be provided side by side. If necessary, the number may be one or three or more, and the size can be determined as necessary. It can also be opened in the bottom plate 2.

底板２及び縦板３の横幅方向中央部であって、二つの止め穴７の中心軸線上に目印８が表示されている。目印８は底板２をＨ型鋼などの金属材１０（図３）の上に載せるときに、金属材１０に表示されているケガキ線１１に位置合わせするためのものである。目印８は底板２と縦板３のいずれか一方にのみ表示することもできる。図示した目印８は線であるが、目印になるものであれば線以外であってもよく、例えば、細い線状のスリットであってもよい。目印８は印刷、ケガキ、その他任意の手段で表示することができる。 A mark 8 is displayed on the central axis of the two stop holes 7 at the center of the bottom plate 2 and the vertical plate 3 in the horizontal width direction. The mark 8 is for aligning the bottom plate 2 with the marking line 11 displayed on the metal material 10 when the bottom plate 2 is placed on the metal material 10 (FIG. 3) such as H-shaped steel. The mark 8 may be displayed only on either the bottom plate 2 or the vertical plate 3. Although the illustrated mark 8 is a line, it may be a line other than the line as long as it serves as a mark, and may be, for example, a thin linear slit. The mark 8 can be displayed by printing, marking, or any other means.

底板２及び縦板３のサイズは同じでもよく、底板２が縦板３より広くてもよい。図２（ａ）（ｂ）のように折り曲げ部４の横幅方向任意の数箇所に補強用のビード９を設けておくこともできる。ビード９は底板２側（折り曲げ方向内側）に突出させる。 The size of the bottom plate 2 and the vertical plate 3 may be the same, and the bottom plate 2 may be wider than the vertical plate 3. As shown in FIGS. 2 (a) and 2 (b), reinforcing beads 9 may be provided at arbitrary positions in the width direction of the bent portion 4. The bead 9 is projected toward the bottom plate 2 side (inside in the bending direction).

［連結金具の使用例１］
