Description

本発明は、建築構造部材に他部材を接合する部材接合構造に関する。 The present invention relates to a member joining structure for joining other members to a building structure member.

従来の部材接合構造として、柱や梁などの建築構造部材に対し、外装パネル固定用ファスナーなどの他部材を接合する部材接合構造が知られている（例えば、特許文献１及び２を参照。）。
この特許文献１の部材接合構造では、建築構造部材としての角形鋼管からなる柱に対して、他部材としてのＡＬＣパネル固定用の補助金物を接合するにあたり、柱の外表面に補助金物を沿わせた姿勢で配置し、その補助金物を建築構造部材に直接溶接により接合し固定している。
一方、特許文献２の部材接合構造では、溶接に頼ることなく、建築構造部材としてのＨ形鋼からなる梁に対して他部材としての縦胴縁固定用の固定板を接合するために、固定板に形成された溝を梁のフランジ部に嵌合させて固定している。更に、この部材接合構造では、当該固定板に連結された止め金の鈎部を梁の反対側のフランジ部に引っ掛けることで、梁に対する固定板の離脱が防止されている。 As a conventional member joining structure, a member joining structure for joining other members such as exterior panel fixing fasteners to building structural members such as columns and beams is known (see, for example, Patent Documents 1 and 2). .
In this member joining structure of Patent Document 1, when joining an auxiliary metal fitting for fixing an ALC panel as another member to a pillar made of a square steel pipe as a building structural member, the auxiliary hardware is placed along the outer surface of the pillar. The auxiliary hardware is joined and fixed to the building structural member directly by welding.
On the other hand, the member joining structure of Patent Document 2 is fixed to join a fixing plate for fixing a vertical trunk edge as another member to a beam made of H-shaped steel as a building structure member without relying on welding. The groove formed on the plate is fitted and fixed to the flange portion of the beam. Further, in this member joining structure, the fixing plate connected to the fixing plate is hooked on the flange portion on the opposite side of the beam, thereby preventing the fixing plate from being detached from the beam.

上記特許文献１の部材接合構造のように、建築構造部材に対する他部材の接合及び固定を溶接のみに頼ると、十分な接合強度を得るために溶接距離が比較的長くなる。このことから、接合のための工数が嵩む上に、建築構造物や他部材において溶接熱による歪みや反り等が発生するという問題がある。
一方、上記特許文献２の部材接合構造のように、建築構造部材に対する他部材の嵌合箇所が一箇所のみである場合には、その嵌合だけでは他部材を十分に固定することができない。そのために、この他部材を建築構造部材に対して強固に固定するための比較的煩雑な止め金などの固定手段を設ける必要があり、この止め金を取り付けるための工数やコストが嵩むという問題がある。 As in the member joint structure of Patent Document 1, if the joining and fixing of other members to the building structure member are relied only on welding, the welding distance becomes relatively long in order to obtain sufficient joint strength. Therefore, there is a problem that the number of man-hours for joining increases, and distortion and warpage due to welding heat occur in the building structure and other members.
On the other hand, when the fitting position of the other member with respect to a building structural member is only one place like the member joining structure of the said patent document 2, other members cannot fully be fixed only by the fitting. Therefore, it is necessary to provide a fixing means such as a relatively complicated clasp for firmly fixing the other member to the building structural member, and there is a problem that the man-hour and cost for attaching the clasp increase. is there.

この実情に鑑み、本発明の主たる課題は、建築構造部材に他部材を接合する部材接合構造において、工数やコストを縮小するべく、歪みや反り等の要因となる溶接による固定を簡略化したり簡単な固定手段を採用した場合でも、建築構造部材に対して他部材を強固に固定することができる技術を提供する点にある。 In view of this situation, the main object of the present invention is to simplify or simplify fixing by welding, which causes factors such as distortion and warpage, in order to reduce man-hours and costs in a member joining structure for joining other members to a building structural member. Even when a simple fixing means is employed, it is to provide a technique capable of firmly fixing other members to the building structural member.

本発明の第１特徴構成は、
建築構造部材に他部材を接合する部材接合構造であって、
前記他部材に形成された複数の嵌合部が、前記建築構造部材に形成された複数の被嵌合部に対して嵌合した状態で、前記他部材が前記建築構造部材に接合され、
前記建築構造部材に、前記被嵌合部として機能する板状部が形成され、
前記他部材が、溝形鋼からなる接合部を有すると共に、当該接合部のウェブ部に、前記嵌合部として機能する溝部が切欠きとして形成され、
前記他部材が、本体と、前記建築構造部材から前記溝形鋼の長手方向に延出して先端部が前記本体の基端部側に固定された前記接合部としての接合補助部材とからなって、前記接合補助部材を介して前記本体が前記建築構造部材に対して離間して配置されている点にある。 The first characteristic configuration of the present invention is:
A member joining structure for joining other members to a building structure member,
In a state where a plurality of fitting portions formed on the other member are fitted to a plurality of fitted portions formed on the building structure member, the other member is joined to the building structure member,
A plate-like portion that functions as the fitted portion is formed on the building structure member,
The other member has a joint portion made of channel steel, and a groove portion functioning as the fitting portion is formed as a notch in the web portion of the joint portion,
The other member includes a main body, and a joining auxiliary member as the joining portion that extends in the longitudinal direction of the channel steel from the building structure member and has a distal end portion fixed to the base end side of the main body. The main body is arranged so as to be separated from the building structure member via the joining auxiliary member.

本特徴構成によれば、建築構造部材に対して、その建築構造部材に形成された複数の被嵌合部の夫々に嵌合する複数の嵌合部が形成された他部材は、当該複数の嵌合部の夫々の箇所において位置決めされることになる。よって、複数の嵌合部の間を結ぶ嵌合部間方向に沿った他部材の移動が十分に抑制され、更には、夫々の嵌合部における嵌合方向を軸にした回転が十分に抑制されることになる。
従って、工数やコストを縮小するべく、歪みや反り等の要因となる溶接による固定を簡略化したり簡単な固定手段を採用した場合でも、建築構造部材に対して他部材を強固に固定することができる。 According to this characteristic configuration, the other member in which the plurality of fitting portions that are fitted into the plurality of fitted portions formed in the building structure member are formed on the building structure member. It will be positioned in each location of a fitting part. Therefore, the movement of the other members along the direction between the fitting parts connecting the plurality of fitting parts is sufficiently suppressed, and furthermore, rotation about the fitting direction in each fitting part is sufficiently suppressed. Will be.
Therefore, in order to reduce man-hours and costs, it is possible to firmly fix other members to building structural members even when fixing by welding, which causes distortion or warping, is simplified or simple fixing means are adopted. it can.

本特徴構成によれば、他部材が有する接合部が溝形鋼で構成され、その溝形鋼のウェブ部側には、嵌合部としての溝部が幅方向全体に亘って形成されることになる。よって、その溝形鋼のウェブ部の両側部から立設する一対のフランジ部には、溝部が殆ど形成されない原型の状態に維持されるため、互いに平行に配置された一対のフランジ部により、接合部の撓み剛性が良好に確保される。
そして、接合部を構成する溝形鋼のウェブ部に形成された長尺の溝部が、建築構造部材に被嵌合部として形成された板状部に対して嵌合部として外嵌するので、接合部の嵌合方向を軸にした回転が一層十分に抑制されることになる。 According to this characteristic configuration, the joining portion of the other member is made of channel steel, and the groove portion as the fitting portion is formed over the entire width direction on the web portion side of the channel steel. Become. Therefore, the pair of flange portions standing from both sides of the web portion of the channel steel is maintained in the original state in which the groove portions are hardly formed. Therefore, the pair of flange portions arranged in parallel to each other are joined together. The bending rigidity of the part is ensured satisfactorily.
And, since the long groove part formed in the web part of the channel steel constituting the joint part is externally fitted as a fitting part to the plate-like part formed as the fitted part in the building structure member, The rotation around the fitting direction of the joint is further sufficiently suppressed.

また、前記建築構造部材の軸方向横側部に、被嵌合部として、互いに平行な一対のフランジ部が形成されていると共に、前記接合部に、前記嵌合部として、前記一対のフランジ部の夫々に外嵌する一対の溝部が形成されていることが好ましい。即ち、接合補助金具に形成された一対の溝部を、建築構造部材の軸方向横側部に形成された一対のフランジ部に外嵌させることで、接合補助金具の特に嵌合方向を軸にした回転を一層抑制することができる。 In addition, a pair of flange portions parallel to each other is formed as a fitted portion on the lateral side portion in the axial direction of the building structural member, and the pair of flange portions as the fitting portion is formed in the joint portion. It is preferable that a pair of grooves that are externally fitted to each other is formed. That is, a pair of groove portions formed in the joining auxiliary metal fittings are externally fitted to a pair of flange parts formed on the lateral sides in the axial direction of the building structural member, so that the fitting direction of the joining auxiliary metal fittings is used as an axis. The rotation can be further suppressed.

更に、前記接合部が、前記建築構造部材の軸方向両横側部の夫々に設けられていること
が好ましい。即ち、建築構造部材の軸方向両横側部の夫々に設けられた接合部の両方に対

また、本発明の第２特徴構成は、前記接合補助部材が、前記建築構造部材の軸方向両横側部の夫々に設けられており、当該夫々の接合補助部材の先端部どうしの間に前記本体が挿入された状態で固定されている点にある。 Furthermore, it is preferable that the said joint part is provided in each of the axial direction both sides of the said building structural member. That is, by joining and fixing other members such as exterior fasteners to both of the joint portions provided on both lateral sides in the axial direction of the building structural member, The load applied to the joint portion can be reduced, and the joint structure necessary for joining the joint portion to the building structure member can be further simplified.
Further, in the second characteristic configuration of the present invention, the joining auxiliary member is provided on each of the both lateral side portions in the axial direction of the building structure member, and between the distal end portions of the respective joining auxiliary members, The main body is fixed in the inserted state.

本発明に係る部材接合構造の実施形態について、図面に基づいて説明する。
図１及び図２に示すように、本実施形態の部材接合構造は、鉄骨１（建築構造部材の一例）に対して、外装パネル１１が固定されるファスナー１５（他部材の一例）を接合する部材接合構造として構成されている。 An embodiment of a member joint structure according to the present invention will be described based on the drawings.
As shown in FIG.1 and FIG.2, the member joining structure of this embodiment joins the fastener 15 (an example of another member) to which the exterior panel 11 is fixed with respect to the steel frame 1 (an example of a building structural member). It is configured as a member joining structure.

The H-shaped steel includes a pair of flange portions 1f that are parallel to each other and a web portion 1w that connects between the central portions of the flange portions 1f. Have.
The exterior panel 11 attached to the steel frame 1 is disposed outside the steel frame 1 in a posture that is substantially parallel to the flange portion 1f of the steel frame 1, and is fixed to the fastener 15 joined to the steel frame 1 in this state. .
In FIG. 1, for ease of explanation, the exterior panel 11 is described as a flat plate, but may be a curved surface or other shapes, for example.

ファスナー１５は、ファスナー本体３（本体に相当する。）と、そのファスナー本体３の基端部側（図１において左端部側）に溶接により固定された接合部としての接合補助部材２とからなり、この接合補助部材２が鉄骨１に接合される。
ファスナー本体３は、Ｈ形鋼を所定の形状に機械加工したものとして構成されており、
かかるファスナー本体３を構成するＨ形鋼は、互いに平行な一対のフランジ部３ｆと、それらフランジ部３ｆの中央部を連結するウェブ部３ｗとを有する。そして、このファスナー本体３は、ウェブ部３ｗを外装パネル１１に対して略平行とすると共に、一対のフランジ部３ｆを鉄骨１のウェブ部１ｗに対して略平行とする姿勢で、鉄骨１と外装パネル１１との間に配置されている。
The fastener 15 includes a fastener main body 3 (corresponding to the main body) and a joining auxiliary member 2 as a joint fixed to the base end side (left end side in FIG. 1 ) of the fastener main body 3 by welding. The joining auxiliary member 2 is joined to the steel frame 1.
The fastener body 3 is configured as a machined H-shaped steel into a predetermined shape,
The H-shaped steel constituting the fastener body 3 has a pair of flange portions 3f parallel to each other and a web portion 3w that connects the central portions of the flange portions 3f. The fastener body 3 has the web portion 3 w substantially parallel to the exterior panel 11 and the pair of flange portions 3 f substantially parallel to the web portion 1 w of the steel frame 1, and the steel frame 1 and the exterior. It is arranged between the panel 11.

更に、このファスナー本体３のフランジ部３ｆの外装パネル１１側には、外装パネル１１の埋め込みボルト７が固定されるブラケット５を、ファスナー本体３に対する姿勢を調整可能な状態で固定可能な調整固定部６が設けられている。尚、この調整固定部６は、ファスナー本体３のフランジ部３ｆ及びそれに重なる状態で配置されたブラケット５の夫々において互いに交差する状態で形態された長孔と、それら長孔同士を締結するボルト及びナットなどで構成されている。 Further, the bracket 5 to which the embedded bolt 7 of the exterior panel 11 is fixed is fixed to the flange 3f side of the flange portion 3f of the fastener body 3 so that the posture with respect to the fastener body 3 can be adjusted. 6 is provided. In addition, this adjustment fixing | fixed part 6 has the long hole formed in the state which mutually cross | intersects in each of the flange part 3f of the fastener main body 3, and the bracket 5 arrange | positioned in the state overlapped with it, the volt | bolt which fastens these long holes, and It is composed of nuts.

また、このファスナー本体３のフランジ部３ｆの外装パネル１１側の両端部（図１における上下端部）には、山形鋼からなる一対の調整補助部材４が接合されている。この調整補助部材４の外装パネル１１側には、押しボルト８が固定されている。そして、この押しボルト８の先端部が外装パネル１１の裏面に当接すると共に、その押しボルト８の外装パネル１１側への突出量が調整されることで、外装パネル１１の倒れ状態が調整される。
更に、鉛直方向に立設される外装パネル１１の背面には、山形鋼からなるブラケット９が固定されており、そのブラケット９には、鉛直姿勢の押しボルト１０が固定されている。そして、この押しボルト１０の下端部がファスナー本体３の調整補助部材４の上面に当接することで、外装パネル１１の自重が調整補助部材４により支持され、更に、その押しボルト１０の外装パネル１１側への突出量が調整されることで、外装パネル１１の上下方向の位置が調整される。 Further, a pair of auxiliary adjustment members 4 made of angle steel are joined to both end portions (upper and lower end portions in FIG. 1) of the flange portion 3f of the fastener body 3 on the exterior panel 11 side. A push bolt 8 is fixed to the adjustment panel 4 on the exterior panel 11 side. And while the front-end | tip part of this pushing bolt 8 contact | abuts to the back surface of the exterior panel 11, the amount of protrusion to the exterior panel 11 side of the pushing bolt 8 is adjusted, and the fall state of the exterior panel 11 is adjusted. .
Further, a bracket 9 made of angle steel is fixed to the back surface of the exterior panel 11 erected in the vertical direction, and a vertical push bolt 10 is fixed to the bracket 9. The lower end portion of the push bolt 10 abuts on the upper surface of the adjustment auxiliary member 4 of the fastener body 3, whereby the weight of the exterior panel 11 is supported by the adjustment auxiliary member 4, and the exterior panel 11 of the push bolt 10 is further supported. The vertical position of the exterior panel 11 is adjusted by adjusting the protruding amount to the side.

このように外装パネル１１が固定されるファスナー本体３を有するファスナー１５は、その基端部側に接合された接合補助部材２を介して、鉄骨１に接合されている。以下、その建築構造部材としての鉄骨１に他部材としてファスナー１５を接合する部材接合構造の詳細について、図３も参照して、説明を加える。 Thus, the fastener 15 having the fastener body 3 to which the exterior panel 11 is fixed is joined to the steel frame 1 via the joining auxiliary member 2 joined to the base end side. Hereinafter, the detail of the member joining structure which joins the fastener 15 as another member to the steel frame 1 as the building structural member will be described with reference to FIG.

ファスナー本体３（図１及び図２参照）の基端部側に溶接により固定された接合補助部材２には、複数の嵌合部Ａが形成されており、その嵌合部Ａが鉄骨１に形成された複数の被嵌合部Ｂに対して嵌合した状態で、ファスナー本体３が鉄骨１に接合されている。
このことで、鉄骨１に対して接合補助部材２は当該複数の嵌合部Ａの夫々の箇所において位置決めされることになる。よって、この接合補助部材２を有するファスナー１５は、複数の嵌合部Ａの間を結ぶ嵌合部間方向（図１において左右方向）に沿った移動が十分に抑制され、更には、夫々の嵌合部Ａにおける嵌合方向（図１の奥行き方向）を軸にした回転が十分に抑制されることになる。 A plurality of fitting portions A are formed on the joining auxiliary member 2 fixed to the base end side of the fastener body 3 (see FIGS. 1 and 2) by welding, and the fitting portions A are formed on the steel frame 1. The fastener body 3 is joined to the steel frame 1 in a state of being fitted to the plurality of formed fitted portions B.
Thus, the joining auxiliary member 2 is positioned at each location of the plurality of fitting portions A with respect to the steel frame 1. Therefore, the fastener 15 having the joining auxiliary member 2 is sufficiently restrained from moving along the inter-fit portion direction (the left-right direction in FIG. 1) connecting the plurality of fit portions A, and further, The rotation around the fitting direction (the depth direction in FIG. 1) in the fitting portion A is sufficiently suppressed.

具体的に、接合補助部材２は、溝形鋼（Ｃ形鋼）からなり、かかる溝形鋼は、互いに平行な一対のフランジ部２ｆと、それらフランジ部２ｆの一方側の夫々の縁部間を連結するウェブ部２ｗとを有する。
接合補助部材２のウェブ部２ｗには、幅方向（一対のフランジ部２ｆに対して垂直の方向）に延出する一対の溝部２ａが形成されている。この溝部２ａの幅は、鉄骨１のフランジ部１ｆの厚さよりも僅かに大きいものとされており、２つの溝部２ａの間隔は、鉄骨１における一対のフランジ部１ｆの間隔と等しいものとされている。また、この溝部２ａは、接合補助部材２としての溝形鋼をレーザー加工機などにより加工し、切欠きとして形成することができる。
尚、接合補助部材２が有する一対のフランジ部２ｆには、ウェブ部２ｗ側の僅かな部分のみに溝部２ａが形成されるだけで、殆どが原型の状態に維持されている。よって、互いに平行に配置された一対のフランジ部２ｆにより、接合補助部材２の撓み剛性が良好に確保されている。 Specifically, the joining auxiliary member 2 is made of channel steel (C-shaped steel), and the channel steel is between a pair of flange portions 2f parallel to each other and the respective edge portions on one side of the flange portions 2f. And a web part 2w for connecting the two.
A pair of groove portions 2 a extending in the width direction (a direction perpendicular to the pair of flange portions 2 f) is formed in the web portion 2 w of the joining auxiliary member 2. The width of the groove portion 2a is slightly larger than the thickness of the flange portion 1f of the steel frame 1, and the interval between the two groove portions 2a is equal to the interval between the pair of flange portions 1f in the steel frame 1. Yes. Further, the groove 2a can be formed as a notch by processing the grooved steel as the joining auxiliary member 2 with a laser processing machine or the like.
Incidentally, the pair of flange portions 2f of the joining auxiliary member 2 are mostly formed in the original state only by forming the groove portions 2a only in a small portion on the web portion 2w side. Therefore, the bending rigidity of the joining auxiliary member 2 is ensured satisfactorily by the pair of flange portions 2f arranged in parallel to each other.

接合補助部材２は、鉄骨１の軸方向両横側部の夫々に設けられている。それら接合補助部材２の夫々は、そのウェブ部２ｗを鉄骨１のウェブ部１ｗ側に向けた姿勢で、一対の溝部２ａを鉄骨１に設けられた一対のフランジ部１ｆに外嵌させた状態で、その溝部２ａの外縁部をフランジ部１ｆに溶接するなどして、鉄骨１に固定される。即ち、接合補助部材２が有する一対の溝部２ａは嵌合部Ａとして機能することになり、一方、その一対の溝部２ａが外嵌する一対の板状部としての鉄骨１が有する一対のフランジ部１ｆが、その嵌合部Ａが嵌合する被嵌合部Ｂとして機能することになる。
そして、接合補助部材２のウェブ部２ｗに形成された長尺の溝部２ａが、鉄骨１に形成されたフランジ部１ｆに対して外嵌するので、接合補助部材２の嵌合方向を軸にした回転が一層十分に抑制されることになる。 The joining auxiliary member 2 is provided on each of the lateral sides of the steel frame 1 in the axial direction. Each of the joining auxiliary members 2 is in a state in which the web portion 2w faces the web portion 1w side of the steel frame 1 and the pair of groove portions 2a are externally fitted to the pair of flange portions 1f provided on the steel frame 1. The outer edge of the groove 2a is fixed to the steel frame 1 by welding it to the flange 1f. That is, the pair of groove portions 2a of the joining auxiliary member 2 functions as the fitting portion A, while the pair of flange portions of the steel frame 1 as a pair of plate-like portions to which the pair of groove portions 2a are fitted. 1f functions as a fitted portion B into which the fitting portion A is fitted.
And since the elongate groove part 2a formed in the web part 2w of the joining auxiliary member 2 is externally fitted with respect to the flange part 1f formed in the steel frame 1, the fitting direction of the joining auxiliary member 2 was made into the axis | shaft. The rotation is further sufficiently suppressed.

また、このように鉄骨１の軸方向両横側部の夫々に接合された２つの接合補助部材２は、当該横側部から外装パネル１１に向けて延出し、それら先端部の間にファスナー本体３が挿入された状態で溶接により固定されている。よって、ファスナー本体３は両横側部から強固に固定されることになる。 Further, the two joining auxiliary members 2 joined to the both lateral sides in the axial direction of the steel frame 1 in this way extend from the lateral side toward the exterior panel 11, and the fastener main body between these distal ends. 3 is fixed by welding in the inserted state. Therefore, the fastener body 3 is firmly fixed from both lateral sides.

また、図５に示すように、山形鋼で構成した接合部３０を接合部として利用する場合には、その山形鋼の一方の辺を構成するウェブ部に一対の溝部３０ａを設け、その一対の溝部３０ａを鉄骨１に形成された一対のフランジ部１ｆに外嵌させる形態で、接合部３０を鉄骨１に接合することができる。 [Another embodiment]
