Description

本発明は、Ｈ型鋼の下側に例えば間仕切壁を設置する工事において、Ｈ型鋼に、先行ピースとしてＣ型鋼を取付けるために用いられる取付け装置に関する。 The present invention relates to a mounting device used for attaching a C-shaped steel as a preceding piece to an H-shaped steel in construction work in which, for example, a partition wall is installed below the H-shaped steel.

従来、Ｈ型鋼の下側に間仕切壁を設置する場合、施工は例えば次のようにして行われる。まずＨ型鋼の下側において、複数本のＣ型鋼をＨ型鋼に直交する方向に等間隔に配置し、Ｈ型鋼のフランジに取付ける。次にＣ型鋼の下面に、Ｈ型鋼に平行に延びるランナーを固定するとともに、ランナーの下面に、鉛直下方に延びる複数本のスタッドを設け、これらのスタッドに石膏ボードを貼り付ける。Ｈ型鋼へのＣ型鋼の取付けは通常、取付け箇所ごとに複数の金具を用いて行われる。すなわち各取付け箇所において、連結金具によってＨ型鋼のフランジにＣ型鋼を取付けた後、固定金具によってＨ型鋼の下側フランジと連結金具を密着させる。 Conventionally, when installing a partition wall below an H-shaped steel, construction is performed, for example, as follows. First, below the H-shaped steel, a plurality of C-shaped steels are arranged at equal intervals in a direction perpendicular to the H-shaped steel, and attached to the flange of the H-shaped steel. Next, a runner extending parallel to the H-shaped steel is fixed to the lower surface of the C-shaped steel, a plurality of studs extending vertically downward are provided on the lower surface of the runner, and gypsum board is attached to these studs. Attachment of C-beam steel to H-beam steel is usually performed using a plurality of metal fittings for each attachment location. That is, at each attachment location, after the C-shaped steel is attached to the flange of the H-shaped steel using a connecting fitting, the lower flange of the H-shaped steel and the connecting fitting are brought into close contact with each other using a fixing fitting.

しかし上述した従来の取付け装置では、特に、Ｃ型鋼がＨ型鋼から突出した状態で固定される、所謂はね出し梁の場合、Ｈ型鋼とＣ型鋼の連結部分におけるモーメントが相対的に大きくなるため、間仕切壁の面内方向の外力、すなわちＣ型鋼の長手方向に直交する方向に対する強度性能が不十分であるという問題があった。 However, with the above-mentioned conventional mounting device, especially in the case of a so-called pop-up beam in which the C-shaped steel is fixed in a state protruding from the H-shaped steel, the moment at the connection part between the H-shaped steel and the C-shaped steel becomes relatively large. However, there was a problem in that the strength performance against external force in the in-plane direction of the partition wall, that is, the strength performance against the direction orthogonal to the longitudinal direction of the C-shaped steel was insufficient.

本発明は、Ｃ型鋼がＨ型鋼から突出した状態であっても、Ｃ型鋼の長手方向に直交する方向に対して十分な強度性能を発揮する取付け装置および連結金具を提供することを目的としている。 An object of the present invention is to provide a mounting device and a connecting fitting that exhibit sufficient strength performance in the direction orthogonal to the longitudinal direction of the C-shaped steel even when the C-shaped steel protrudes from the H-shaped steel. .

第１の発明は、ウェブの両端を折り曲げて成る第１および第２フランジを有するＣ型鋼を、Ｈ型鋼に交差させ、かつ突出した状態で、第１フランジをＨ型鋼のフランジ外面に密着させて固定する取付け装置である。この取付け装置は、Ｈ型鋼のフランジに取付けられる固定金具と、第１フランジをＨ型鋼のフランジ外面に密着させるための連結金具とを備え、連結金具は、第２フランジに密着する第１水平板部と、第１水平板部の両端から垂直方向に延びて、Ｃ型鋼のウェブまたはリップ部に係合する一対の垂直板部と、一対の垂直板部から水平方向に延び、Ｈ型鋼のフランジ外面に対向または当接する第２水平板部と、一対の垂直板部からＣ型鋼の突出方向に膨出し、Ｃ型鋼のウェブまたはリップ部に係合する一対の膨出部とを有し、一対の膨出部には、Ｃ型鋼のウェブまたはリップ部に対応した箇所にビス孔が形成され、固定金具は、Ｈ型鋼のフランジ外面と第２水平板部とを密着させる方向に押圧することを特徴としている。 In the first invention, a C-shaped steel having first and second flanges formed by bending both ends of a web is crossed over an H-shaped steel, and the first flange is brought into close contact with the outer surface of the flange of the H-shaped steel in a protruding state. It is a mounting device for fixing. This mounting device includes a fixing fitting that is attached to the flange of the H-shaped steel, and a connecting fitting that brings the first flange into close contact with the outer surface of the flange of the H-shaped steel. a pair of vertical plate parts that extend vertically from both ends of the first horizontal plate part and engage with the web or lip part of the C-shaped steel; and a flange of the H-shaped steel that extends horizontally from the pair of vertical plate parts. A second horizontal plate portion that faces or abuts the outer surface, and a pair of bulge portions that bulge out from the pair of vertical plate portions in the protruding direction of the C-shaped steel and engage with the web or lip portion of the C-shaped steel. A screw hole is formed in the bulge part at a location corresponding to the web or lip part of the C-shaped steel, and the fixing fitting is pressed in a direction to bring the outer surface of the flange of the H-shaped steel and the second horizontal plate part into close contact. It is a feature.

膨出部には、Ｈ型鋼のフランジの端面に当接する当接部が形成されることが好ましい。また、一対の膨出部にそれぞれ形成されたビス孔において、Ｈ型鋼のフランジの端面からの距離が相互に異なっていてもよい。 It is preferable that the bulging portion is formed with an abutting portion that abuts the end face of the flange of the H-shaped steel. Moreover, the distances from the end surface of the flange of the H-shaped steel may be different between the screw holes formed in the pair of bulges.

第２の発明は、ウェブの両端を折り曲げて成る第１および第２フランジを有するＣ型鋼を、Ｈ型鋼に交差させ、かつ突出した状態で、第１フランジをＨ型鋼のフランジ外面に密着させて固定する取付け装置の一部を構成する連結金具である。この連結金具は、第２フランジに密着する第１水平板部と、第１水平板部の両端から垂直方向に延びて、Ｃ型鋼のウェブまたはリップ部に係合する一対の垂直板部と、一対の垂直板部から水平方向に延び、Ｈ型鋼のフランジ外面に対向または当接する第２水平板部と、一対の垂直板部からＣ型鋼の突出方向に膨出し、Ｃ型鋼のウェブまたはリップ部に係合する一対の膨出部とを有し、一対の膨出部には、Ｃ型鋼のウェブまたはリップ部に対応した箇所にビス孔が形成されることを特徴としている。 In a second invention, a C-shaped steel having first and second flanges formed by bending both ends of a web is crossed over an H-shaped steel, and the first flange is brought into close contact with the outer surface of the flange of the H-shaped steel in a protruding state. This is a connecting metal fitting that forms part of the fixing device. This connecting fitting includes a first horizontal plate portion that closely contacts the second flange, and a pair of vertical plate portions that extend in the vertical direction from both ends of the first horizontal plate portion and engage with the web or lip portion of the C-shaped steel. A second horizontal plate part extends horizontally from the pair of vertical plate parts and faces or abuts the outer surface of the flange of the H-shaped steel, and a web or lip part of the C-shaped steel extends from the pair of vertical plate parts in the protruding direction of the C-shaped steel. It has a pair of bulges that engage with the bulges, and screw holes are formed in the pair of bulges at locations corresponding to the webs or lip portions of the C-shaped steel.

以下、図面を参照して本発明の実施形態を説明する。
図１は本発明の一実施形態である取付け装置を用いた組立て体１０を示す斜視図である。この組立て体１０は、Ｃ型鋼３０を介して、壁２０をＨ型鋼１１に固定したものである。Ｈ型鋼１１は例えば、建屋の天井に平行に設置され、建屋の躯体の一部である。Ｈ型鋼１１の下側フランジ１２には複数のＣ型鋼３０が固定され、これらのＣ型鋼３０は、Ｈ型鋼１１に交差し、下側フランジ１２から突出した状態で固定される。すなわちＣ型鋼３０ははね出し梁（片持ち梁）であり、その先端部分の下面には、Ｈ型鋼１１に平行に延びるランナー２１が固定される。ランナー２１は壁２０の上縁部である。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing an assembly 10 using a mounting device according to an embodiment of the present invention. In this assembly 10, a wall 20 is fixed to an H-shaped steel 11 via a C-shaped steel 30. For example, the H-shaped steel 11 is installed parallel to the ceiling of a building and is part of the building frame. A plurality of C-shaped steels 30 are fixed to the lower flange 12 of the H-shaped steel 11, and these C-shaped steels 30 are fixed in a state that intersects with the H-shaped steel 11 and protrudes from the lower flange 12. That is, the C-shaped steel 30 is a projecting beam (cantilever beam), and a runner 21 extending parallel to the H-shaped steel 11 is fixed to the lower surface of the tip portion thereof. Runner 21 is the upper edge of wall 20.

ランナー２１は溝型鋼であり、溝を下方に向けて配置され、そのウェブはＣ型鋼３０のフランジに固定される。ランナー２１の溝内には複数のスタッド２２の上端が嵌め込まれて固定される。スタッド２２は所定間隔を空けて配置され、ランナー２１とスタッド２２から構成される枠体の両面には、石膏ボード２３が貼り付けされ、壁２０が構成される。 The runner 21 is a channel steel, arranged with the groove facing downward, and its web is fixed to the flange of the C-beam 30. The upper ends of the plurality of studs 22 are fitted into the grooves of the runner 21 and fixed. The studs 22 are arranged at predetermined intervals, and gypsum boards 23 are attached to both sides of the frame made up of the runners 21 and the studs 22 to form the wall 20.

Ｃ型鋼３０は通常の構成を有し、ウェブ３１の上下両端を折り曲げて成る第１および第２フランジ３２、３３を備え、これらのフランジ３２、３３の先端には、ウェブ３１に平行に折り曲げられたリップ部３４、３５が形成される。Ｃ型鋼３０の長手方向の一方の端部は、第１固定金具４０によってＨ型鋼１１のフランジ１２の幅方向の一方の端部に固定される。Ｃ型鋼３０の長手方向の他方の端部はフランジ１２の幅方向の他方の端部から突出し、ビスにより、ランナー２１のウェブの上面が固定される。Ｃ型鋼３０の中間部分は２つの第２固定金具５０と連結金具６０によってＨ型鋼１１のフランジ１２の幅方向の他方の端部に固定される。第２固定金具５０と連結金具６０は本発明の一実施形態である取付け装置を構成する。 The C-shaped steel 30 has a normal configuration, and includes first and second flanges 32 and 33 formed by bending both the upper and lower ends of a web 31. At the tips of these flanges 32 and 33, there are flanges bent parallel to the web 31. Lip portions 34 and 35 are formed. One end of the C-shaped steel 30 in the longitudinal direction is fixed to one end of the flange 12 of the H-shaped steel 11 in the width direction by a first fixture 40 . The other end of the C-shaped steel 30 in the longitudinal direction protrudes from the other end of the flange 12 in the width direction, and the upper surface of the web of the runner 21 is fixed with a screw.

The second fixture 50 and the connecting fixture 60 constitute a mounting device that is an embodiment of the present invention.

第１および第２固定金具４０、５０は共にＨ型鋼１１のフランジ１２に取付けられるが、その機能と構造は異なる。すなわち第１固定金具４０は単体でＣ型鋼３０をＨ型鋼１１に固定し、第２固定金具５０は連結金具６０と協働してＣ型鋼３０をＨ型鋼１１に固定する。 The first and second fixtures 40, 50 are both attached to the flange 12 of the H-shaped steel 11, but their functions and structures are different. That is, the first fixture 40 alone fixes the C-shaped steel 30 to the H-shaped steel 11, and the second fixture 50 cooperates with the connecting fixture 60 to fix the C-shaped steel 30 to the H-shaped steel 11.

図２、３を参照して第１固定金具４０の構成を説明する。第１固定金具４０は金属板をＺ形に折り曲げて成形され、第１水平板部４１はビス４２によってＣ型鋼３０の第１フランジ３２に固定される。第１水平板部４１から垂直方向に延びる垂直板部４３はＨ型鋼１１の下側フランジ１２の端面に当接し、垂直板部４３から水平方向に延びる第２水平板部４４はボルト４５とナット４６によって、下側フランジ１２の上面に固定される。 The configuration of the first fixture 40 will be described with reference to FIGS. 2 and 3. The first fixture 40 is formed by bending a metal plate into a Z shape, and the first horizontal plate portion 41 is fixed to the first flange 32 of the C-shaped steel 30 with screws 42 . A vertical plate part 43 extending in the vertical direction from the first horizontal plate part 41 contacts the end surface of the lower flange 12 of the H-shaped steel 11, and a second horizontal plate part 44 extending in the horizontal direction from the vertical plate part 43 connects bolts 45 and nuts. 46 to the upper surface of the lower flange 12.

図４、７、８を参照して第２固定金具５０と連結金具６０の構成を説明する。第２固定金具５０は金属板を折り曲げて成形され、Ｈ型鋼１１の下側フランジ１２に取付けられる。第２固定金具５０は、第１水平板部５１と、第１水平板部５１から垂直下方に延びる第１垂直板部５２と、第１垂直板部５２に対して垂直に折り曲げられた第２および第３垂直板部５３、５４とを有する。第１水平板部５１は、下側フランジ１２の上面に対向し、ボルト５５とナット５６により下側フランジ１２に固定される。第１垂直板部５２には、第２固定金具５０と連結金具６０をＣ型鋼３０に固定するためのビスが貫通するビス孔５７が穿設される。第２および第３垂直板部５３、５４は連結金具６０に当接する。 The configuration of the second fixture 50 and the connecting fixture 60 will be described with reference to FIGS. 4, 7, and 8. The second fixture 50 is formed by bending a metal plate, and is attached to the lower flange 12 of the H-shaped steel 11. The second fixture 50 includes a first horizontal plate portion 51, a first vertical plate portion 52 extending vertically downward from the first horizontal plate portion 51, and a second vertical plate portion 52 bent perpendicularly to the first vertical plate portion 52. and third vertical plate portions 53 and 54. The first horizontal plate portion 51 faces the upper surface of the lower flange 12 and is fixed to the lower flange 12 with bolts 55 and nuts 56. The first vertical plate portion 52 is provided with a screw hole 57 through which a screw for fixing the second fixture 50 and the connecting fixture 60 to the C-shaped steel 30 passes. The second and third vertical plate portions 53 and 54 abut against the connecting fitting 60.

連結金具６０は金属板を折り曲げて成形され、Ｃ型鋼３０の第１フランジ３２をＨ型鋼１１の下側フランジ１２の外面（下面）に密着させるために用いられる。連結金具６０は、第１水平板部６１と、第１水平板部６１の両端から垂直上方に延びる一対の垂直板部６２と、垂直板部６２から水平方向に延びる第２水平板部６３と、一対の垂直板部６２に連設された一対の膨出部６４とを有する。 The connecting fitting 60 is formed by bending a metal plate, and is used to bring the first flange 32 of the C-shaped steel 30 into close contact with the outer surface (lower surface) of the lower flange 12 of the H-shaped steel 11. The connecting fitting 60 includes a first horizontal plate part 61, a pair of vertical plate parts 62 extending vertically upward from both ends of the first horizontal plate part 61, and a second horizontal plate part 63 extending horizontally from the vertical plate part 62. , and a pair of bulges 64 connected to a pair of vertical plate parts 62.

第１水平板部６１はＣ型鋼３０の第２フランジ３３に密着し、第２フランジ３３に固定するためのビスが貫通するビス孔６７が穿設される。垂直板部６２はＣ型鋼３０のウェブ３１またはリップ部３４に係合する。第２水平板部６３は、Ｈ型鋼１１の下側フランジ１２の外面に対向または当接する。一対の膨出部６４は垂直板部６２からＣ型鋼３０の突出方向（はね出し方向）に膨出し、膨出部６４には、Ｃ型鋼３０のウェブ３１またはリップ部３４に対応した箇所にビス孔６５が形成される。このビス孔６５は第２固定金具５０のビス孔５７の位置に対応している。また、膨出部６４の第２水平板部６３側の端面はＨ型鋼１１の下側フランジ１２の端面に当接する当接部６６である。 The first horizontal plate portion 61 is in close contact with the second flange 33 of the C-shaped steel 30, and has a screw hole 67 through which a screw for fixing to the second flange 33 passes. The vertical plate portion 62 engages the web 31 or lip portion 34 of the C-shaped steel 30. The second horizontal plate portion 63 faces or abuts the outer surface of the lower flange 12 of the H-shaped steel 11. The pair of bulging portions 64 bulge out from the vertical plate portion 62 in the protruding direction (springing direction) of the C-shaped steel 30, and the bulging portions 64 have a portion corresponding to the web 31 or lip portion 34 of the C-shaped steel 30. A screw hole 65 is formed. This screw hole 65 corresponds to the position of the screw hole 57 of the second fixture 50. Further, the end surface of the bulging portion 64 on the second horizontal plate portion 63 side is a contact portion 66 that comes into contact with the end surface of the lower flange 12 of the H-shaped steel 11.

次に図２から６を参照して、Ｈ型鋼１１にＣ型鋼３０を取付けて固定する作業工程を説明する。この例では、Ｃ型鋼３０はＨ型鋼１１に交差させ、かつＨ型鋼１１から突出した状態で固定される。 Next, with reference to FIGS. 2 to 6, a working process for attaching and fixing the C-shaped steel 30 to the H-shaped steel 11 will be described. In this example, the C-shaped steel 30 intersects with the H-shaped steel 11 and is fixed in a state protruding from the H-shaped steel 11.

第１工程（図２）では、Ｃ型鋼３０の第１フランジ３２の一端の上面に、第１固定金具４０がビス４２により取付けられる。第２工程（図３）では、第１固定金具４０の第２水平板部４４とＣ型鋼３０の第１フランジ３２との間にＨ型鋼１１の下側フランジ１２が挟まれるようにして、Ｃ型鋼３０がＨ型鋼１１に対して位置決めされる。そしてボルト４５が回されて所定の押圧力で下側フランジ１２の上面に固定され、Ｃ型鋼３０が第１固定金具４０によってＨ型鋼１１に仮止めされる。 In the first step (FIG. 2), the first fixture 40 is attached to the upper surface of one end of the first flange 32 of the C-shaped steel 30 with screws 42. In the second step (FIG. 3), the lower flange 12 of the H-shaped steel 11 is sandwiched between the second horizontal plate portion 44 of the first fixture 40 and the first flange 32 of the C-shaped steel 30. The type steel 30 is positioned relative to the H type steel 11. Then, the bolt 45 is turned and fixed to the upper surface of the lower flange 12 with a predetermined pressing force, and the C-shaped steel 30 is temporarily fixed to the H-shaped steel 11 by the first fixing fitting 40.

第３工程（図４）では連結金具６０がＣ型鋼３０とＨ型鋼１１の下側フランジ１２の間に装着される。連結金具６０は、第１水平板部６１がＣ型鋼３０の第２フランジ３３の下面に当接するようにして、Ｃ型鋼３０に嵌合され、当接部６６が下側フランジ１２の端面に当接した位置に定められる。 In the third step (FIG. 4), the connecting fitting 60 is installed between the lower flange 12 of the C-shaped steel 30 and the H-shaped steel 11. The connecting fitting 60 is fitted to the C-shaped steel 30 such that the first horizontal plate portion 61 contacts the lower surface of the second flange 33 of the C-shaped steel 30, and the contact portion 66 contacts the end surface of the lower flange 12. It is set in a position where they are in contact with each other.

第４工程（図５）では、一対の第２固定金具５０が下側フランジ１２に取付けられる。このとき第２固体金具５０は、第１水平板部５１の下面が下側フランジ１２の上面に対向し、第３垂直板部５４の上端が連結金具６０の第２水平板部６３の下面に当接するように取付けられる。また、この状態において、一方の第２固定金具５０の第２垂直板部５３が連結金具６０の膨出部６４に当接し、他方の第２固定金具５０の第３垂直板部５４が連結金具６０の垂直板部６２に当接する。ここで連結金具６０のビス孔６７（図４参照）にビス６８が挿通され、連結金具６０はＣ型鋼３０の第２フランジ３３に固定される。そしてボルト５５が回されて所定の押圧力で下側フランジ１２の上面に固定され、Ｃ型鋼３０が第２固定金具５０と連結金具６０によってＨ型鋼１１に仮止めされる。 In the fourth step (FIG. 5), a pair of second fixtures 50 are attached to the lower flange 12. At this time, in the second solid metal fitting 50, the lower surface of the first horizontal plate part 51 faces the upper surface of the lower flange 12, and the upper end of the third vertical plate part 54 faces the lower surface of the second horizontal plate part 63 of the connecting metal fitting 60. They are installed so that they are in contact with each other. In this state, the second vertical plate part 53 of one second fixture 50 is in contact with the bulging part 64 of the connecting fixture 60, and the third vertical plate part 54 of the other second fixture 50 is in contact with the connecting fixture 60. It abuts against the vertical plate portion 62 of 60. Here, the screw 68 is inserted into the screw hole 67 (see FIG. 4) of the connecting fitting 60, and the connecting fitting 60 is fixed to the second flange 33 of the C-shaped steel 30. Then, the bolt 55 is turned and fixed to the upper surface of the lower flange 12 with a predetermined pressing force, and the C-shaped steel 30 is temporarily fixed to the H-shaped steel 11 by the second fixing fitting 50 and the connecting fitting 60.

第５工程（図６）では本締めが行われ、Ｃ型鋼３０がＨ型鋼１１に強固に固定される。まず第１固定金具４０において、ナット４６を回すことによりボルト４５が第２水平板部４４に対して回動不能になり、Ｃ型鋼３０は第１固定金具４０によってＨ型鋼１１の下側フランジ１２に強固に固定される。 In the fifth step (FIG. 6), final tightening is performed, and the C-shaped steel 30 is firmly fixed to the H-shaped steel 11. First, in the first fixture 40, by turning the nut 46, the bolt 45 becomes unrotatable with respect to the second horizontal plate part 44, and the C-shaped steel 30 is attached to the lower flange 12 of the H-shaped steel 11 by the first fixture 40. is firmly fixed.

第２固定金具５０でも同様に、ナット５６を回すことによりボルト５５が下側フランジ１２に対して回動不能になり、第２固定金具５０は、Ｈ型鋼１１の下側フランジ１２の外面と連結金具６０の第２水平板部６３とを密着させる方向に押圧し、Ｃ型鋼３０はＨ型鋼１１に強固に固定される。また第２固定金具５０のビス孔５７と連結金具６０のビス孔６５にビス５８が通され、ビス５８はＣ型鋼３０のウェブ３１とリップ部３４に螺着される。これによりＣ型鋼３０は下側フランジ１２にさらに強固に固定される。 Similarly, in the second fixture 50, by turning the nut 56, the bolt 55 becomes unrotatable with respect to the lower flange 12, and the second fixture 50 is connected to the outer surface of the lower flange 12 of the H-shaped steel 11. The C-shaped steel 30 is firmly fixed to the H-shaped steel 11 by pressing in a direction to bring the second horizontal plate portion 63 of the metal fitting 60 into close contact with each other. Further, a screw 58 is passed through the screw hole 57 of the second fixing metal fitting 50 and the screw hole 65 of the connecting metal fitting 60, and the screw 58 is screwed into the web 31 and the lip portion 34 of the C-shaped steel 30. Thereby, the C-shaped steel 30 is more firmly fixed to the lower flange 12.

図８、９は連結金具６０と一対の第２固定金具５０を組み合わせた構造を示している。これらの図において、右側に示される第２固定金具５０では、第１垂直板部５２と第２垂直板部５３の間の角部が連結金具６０の膨出部６４に当接し、左側に示される第２固定金具５０では、第２垂直板部５３が膨出部６４に当接している。また右側に示される第２固定金具５０では、第３垂直板部５４が連結金具６０の垂直板部６２に当接し、左側に示される第２固定金具５０では、第１垂直板部５２と第３垂直板部５４の間の角部が連結金具６０の垂直板部６２に当接している。 8 and 9 show a structure in which a connecting fitting 60 and a pair of second fixing fittings 50 are combined. In these figures, in the second fixture 50 shown on the right side, the corner between the first vertical plate part 52 and the second vertical plate part 53 comes into contact with the bulge part 64 of the connecting metal fitting 60, and the second fixture 50 shown on the left side In the second fixture 50 , the second vertical plate portion 53 is in contact with the bulge portion 64 . Further, in the second fixture 50 shown on the right side, the third vertical plate portion 54 is in contact with the vertical plate portion 62 of the connecting metal fitting 60, and in the second fixture 50 shown on the left side, the third vertical plate portion 54 is in contact with the vertical plate portion 62 of the connecting metal fitting 60. The corner between the three vertical plate parts 54 is in contact with the vertical plate part 62 of the connecting fitting 60.

上述したように、左右の第２固定金具５０では、連結金具６０に当接する部位が異なり、また第２垂直板部５３と第３垂直板部５４の幅も異なるため、第２垂直板部５２と連結金属６０の垂直板部５２との成す角が異なる。したがって、ビス５８により第２固定金具５０を連結金具６０とＣ型鋼３０に固定した状態において、ビス５８がＣ型鋼３０の長手軸に対して成す角は左右の第２固定金具５０で異なり、図示例では、右側の角度Ａは７５．７°、左側の角度Ｂは６２．６°である。すなわち連結金具６０においてビス５８が取付けられる位置が相対的に異なり、図７に示されるように、一対の膨出部６４にそれぞれ形成されたビス孔６５において、当接部６６すなわちＨ型鋼１１のフランジ１２の端面からの距離が相互に異なる。 As described above, the left and right second fixing metal fittings 50 have different parts that contact the connecting metal fittings 60, and the widths of the second vertical plate part 53 and the third vertical plate part 54 are also different, so that the second vertical plate part 52 The angle formed by the vertical plate portion 52 of the connecting metal 60 is different. Therefore, when the second fixing metal fitting 50 is fixed to the connecting metal fitting 60 and the C-shaped steel 30 with the screw 58, the angle that the screw 58 makes with respect to the longitudinal axis of the C-shaped steel 30 is different between the left and right second fixing metal fittings 50, and In the example shown, angle A on the right side is 75.7° and angle B on the left side is 62.6°. That is, the positions where the screws 58 are installed in the connecting fittings 60 are relatively different, and as shown in FIG. The distances from the end faces of the flanges 12 are different from each other.

図９、１０を参照して本実施形態の効果を説明する。なお図１０（ａ）は組立て体１０を上方から見た平面図であり、図１０（ｂ）は組立て体１０をＨ型鋼１１の長手方向から見た側面図である。上述したように、本実施形態では連結金具６０に膨出部６４を設け、膨出部６４には、Ｃ型鋼３０のウェブ３１またはリップ部３４に対応した箇所にビス孔６５を形成した。したがって連結金具６０は、Ｃ型鋼３０に対して所望の位置に、高精度かつ強固に固定され、Ｃ型鋼３０のＨ型鋼１１に対する連結強度が向上する。このため、Ｃ型鋼３０がＨ型鋼１１からはね出した構造であっても、壁２０に作用する面内方向（水平方向および鉛直方向）に対する十分な強度性能が発揮される。 The effects of this embodiment will be explained with reference to FIGS. 9 and 10. Note that FIG. 10(a) is a plan view of the assembly 10 viewed from above, and FIG. 10(b) is a side view of the assembly 10 viewed from the longitudinal direction of the H-shaped steel 11. As described above, in this embodiment, the connecting fitting 60 is provided with the bulging portion 64, and the screw hole 65 is formed in the bulging portion 64 at a location corresponding to the web 31 or the lip portion 34 of the C-shaped steel 30. Therefore, the connecting fitting 60 is fixed to the C-shaped steel 30 at a desired position with high precision and firmly, and the connection strength of the C-shaped steel 30 to the H-shaped steel 11 is improved. Therefore, even in a structure in which the C-shaped steel 30 protrudes from the H-shaped steel 11, sufficient strength performance in the in-plane directions (horizontal and vertical directions) acting on the wall 20 is exhibited.
