また、２つのＬ字状板材５１１，５２１の重なり代を調整して組み合わせることができるため、縦筒部５１及び横筒部５２の強度設計を行い易い。
また、平板状の鋼板の板厚の種類が豊富であるため、鋼板の板厚を適宜選択することで、縦筒部５１及び横筒部５２の強度設計を行い易い。

Therefore, since the L-shaped plate members 511, 521 can be formed by bending the flat plate-shaped steel plate, the vertical cylinder portion 51 and the horizontal cylinder portion 52 are cheaper than, for example, using a steel pipe formed by rolling steel into a tubular shape. Can be made into.
Further, since the overlapping allowances of the two L-shaped plate members 511, 521 can be adjusted and combined, it is easy to design the strength of the vertical cylinder portion 51 and the horizontal cylinder portion 52.
Further, since there are many types of flat plate-shaped steel plates, it is easy to design the strength of the vertical cylinder portion 51 and the horizontal cylinder portion 52 by appropriately selecting the plate thickness of the steel plate.
Further, even if the vertical tubular portion 51 is configured by combining two L-shaped plate members 511 and joined, and the horizontal tubular portion 52 is configured by combining and joining two L-shaped plate members 521, it is also lateral. Since the intermediate portion of the tubular portion 52 in the longitudinal direction is joined to the vertical tubular portion 51 at the notch 512a, and one end of the horizontal tubular portion 52 in the longitudinal direction is joined to the vertical tubular portion 51 at the through slit 513a.

また、本実施形態においては、補強板５３は、横筒部５２の上面に接合されると共に、横筒部５２の幅方向の両端部それぞれが一対の側面板５１４それぞれの内面に接合される。これにより、支柱２と梁４の接続構造５０を、横筒部５２の長手方向の一端部側において、補強板５３により補強できる。よって、接続強度を向上させることができる。 Further, in the present embodiment, the reinforcing plate 53 is joined to the upper surface of the horizontal cylinder portion 52, and both ends of the horizontal cylinder portion 52 in the width direction are joined to the inner surfaces of the pair of side plates 514. As a result, the connection structure 50 between the column 2 and the beam 4 can be reinforced by the reinforcing plate 53 on the one end side in the longitudinal direction of the horizontal cylinder portion 52. Therefore, the connection strength can be improved.

図８に示すように、第２実施形態の接続部材５Ａの横筒部５２Ａは、第１実施形態の接続部材５の横筒部５２よりも受ける荷重が大きい場合に対応できるように、長手方向の長さを長く形成すると共に、第１実施形態の一対のＬ字状板材５２１，５２１の重なり代５２１ｃよりも一対のコ字状板材５２５，５２５の重なり代５２５ｃを大きく構成する。これにより、支柱２と梁４の接続構造５０Ａにおいて、接続強度を向上させることで、第１実施形態よりも受ける荷重が大きい場合に対応できるように構成している。 As shown in FIG. 8, the horizontal cylinder portion 52A of the connecting member 5A of the second embodiment can handle a case where the load received is larger than that of the horizontal cylinder portion 52 of the connecting member 5 of the first embodiment in the longitudinal direction. In addition to forming a longer length, the overlapping allowance 525c of the pair of U-shaped plate members 525 and 525 is formed larger than the overlapping allowance 521c of the pair of L-shaped plate members 521 and 521 of the first embodiment. As a result, the connection structure 50A between the support column 2 and the beam 4 is configured to be able to cope with a case where the load received is larger than that in the first embodiment by improving the connection strength.

接続部材５Ａは、縦方向Ｔに延びる縦筒部５１（縦部材）と、縦筒部５１の上端部から縦筒部５１に交差する横方向Ｙに延びる横筒部５２Ａ（横部材）と、補強板５３（上面補強部材）と、を有する。縦筒部５１及び補強板５３の構成は、第１実施形態と同様であるため、その説明を省略する。また、第２実施形態における溶接箇所も、第１実施形態と同様であるため、その説明を省略する。 The connecting member 5A includes a vertical cylinder portion 51 (vertical member) extending in the vertical direction T, and a horizontal cylinder portion 52A (horizontal member) extending in the horizontal direction Y intersecting the vertical cylinder portion 51 from the upper end portion of the vertical cylinder portion 51. It has a reinforcing plate 53 (upper surface reinforcing member). Since the configurations of the vertical cylinder portion 51 and the reinforcing plate 53 are the same as those in the first embodiment, the description thereof will be omitted. Further, since the welded portion in the second embodiment is the same as that in the first embodiment, the description thereof will be omitted.

第２実施形態の横筒部５２Ａは、第１実施形態の横筒部５２よりも長手方向の長さが長く形成される。横筒部５２Ａは、図８及び図９に示すように、横方向Ｙに延びると共に断面がコ字状の一対のコ字状板材５２５，５２５が、反転された状態で周方向に組み合わされて接合されることで構成される。一対のコ字状板材５２５，５２５は、例えば、平板状の鋼板を折り曲げることで形成される。 The horizontal cylinder portion 52A of the second embodiment is formed to have a longer length in the longitudinal direction than the horizontal cylinder portion 52 of the first embodiment.

It is composed of being joined. The pair of U-shaped plate members 525 and 525 are formed, for example, by bending a flat plate-shaped steel plate.

一対のコ字状板材５２５，５２５は、図９に示すように、組み合わされた状態において、コの字の上面及び下面それぞれにおいて重なる重なり代５２５ｃを有する。
重なり代５２５ｃは、一方のコ字状板材５２５の上面と他方のコ字状板材の下面とが重なった状態で、横方向Ｙに延びて形成される。第２実施形態の一対のコ字状板材５２５の重なり代５２５ｃは、横筒部５２Ａの上面板５２２及び下面板５２３において、幅方向Ｈの全域に亘って重なって配置されている。 As shown in FIG. 9, the pair of U-shaped plate members 525 and 525 have overlapping allowances 525c on the upper surface and the lower surface of the U-shape in the combined state.
The overlapping allowance 525c is formed so as to extend in the lateral direction Y in a state where the upper surface of one U-shaped plate material 525 and the lower surface of the other U-shaped plate material overlap. The overlapping allowance 525c of the pair of U-shaped plate members 525 of the second embodiment is arranged so as to overlap over the entire width direction H in the upper surface plate 522 and the lower surface plate 523 of the horizontal cylinder portion 52A.

重なり代５２５ｃにおいては、一対のコ字状板材５２５，５２５は、それぞれ、周方向の一端部５２５ａの端面が内部に配置されると共に、周方向の他端部５２５ｂの端面が外部に露出するように組み合わされた状態で、互いが接合されている。重なり代５２５ｃにおいては、一方のコ字状板材５２５の周方向の他端部５２５ｂの横方向Ｙに延びる端面は、横方向Ｙに離間する複数の溶接箇所５２５ｄにおいて、他方のコ字状板材５２５の折り曲げ部分に溶接により接合されている。 In the overlapping allowance 525c, in each of the pair of U-shaped plate members 525 and 525, the end face of the one end portion 525a in the circumferential direction is arranged inside, and the end face of the other end portion 525b in the circumferential direction is exposed to the outside. They are joined to each other in the state of being combined with. In the overlapping allowance 525c, the end face extending in the lateral direction Y of the other end portion 525b in the circumferential direction of one U-shaped plate material 525 is the other U-shaped plate material 525 at a plurality of welded points 525d separated in the lateral direction Y. It is joined to the bent part of.

第２実施形態の一対のコ字状板材５２５の重なり代５２５ｃは、第１実施形態の一対のＬ字状板材５２１，５２１の重なり代５２１ｃよりも、周方向の長さが長い範囲で重なって形成されている。具体的には、横筒部５２Ａの上面板５２２及び下面板５２３においては、幅方向Ｈの全域において、板材が二重に重なって構成されている。これにより、第１実施形態の横筒部５２よりも受ける荷重が大きい場合においても、第２実施形態の重なり代５２５ｃを、第１実施形態の重なり代５２１ｃよりも長くすることで、横筒部５２Ａの強度を確保している。 The overlapping allowance 525c of the pair of U-shaped plate members 525 of the second embodiment overlaps in a range longer than the overlapping allowance 521c of the pair of L-shaped plate members 521 and 521 of the first embodiment. It is formed. Specifically, in the upper surface plate 522 and the lower surface plate 523 of the horizontal cylinder portion 52A, the plate materials are doubly overlapped in the entire width direction H. As a result, even when the load received is larger than that of the horizontal cylinder portion 52 of the first embodiment, the overlapping margin 525c of the second embodiment is made longer than the overlapping margin 521c of the first embodiment, so that the horizontal cylinder portion is formed. The strength of 52A is secured.

第２実施形態においては、図１０及び図１１に示すように、縦筒部５１の貫通スリット５１３ａの幅Ｓ２は、板材が二重に重って構成された下面板５２３Ａの横方向Ｙの一端部５２３ａの厚さＴ２よりも、僅かに大きく形成される。横筒部５２の下面板５２３Ａの横方向Ｙの一端部５２３ａは、貫通スリット５１３ａに対向して配置され、背面側から視た場合に、厚さ方向の厚さＴ２が、貫通スリット５１３ａの幅Ｓ２の範囲内に収まるように配置されている。 In the second embodiment, as shown in FIGS. 10 and 11, the width S2 of the through slit 513a of the vertical cylinder portion 51 is one end in the lateral direction Y of the lower surface plate 523A formed by doubly overlapping the plate materials. It is formed to be slightly larger than the thickness T2 of the portion 523a. One end portion 523a of the lower surface plate 523A of the horizontal cylinder portion 52 in the lateral direction Y is arranged so as to face the through slit 513a, and when viewed from the back side, the thickness T2 in the thickness direction is the width of the through slit 513a. It is arranged so as to be within the range of S2.

以上のように構成される第２実施形態の支柱２と梁４の接続構造５０Ａによれば、第１実施形態と同様の効果を奏すると共に、第１実施形態の接続強度よりも高い接続強度を得ることができる。 According to the connection structure 50A between the support column 2 and the beam 4 of the second embodiment configured as described above, the same effect as that of the first embodiment is obtained, and the connection strength higher than that of the first embodiment is achieved.
