Description

本発明は、スチールハウスを始めとする薄板軽量形鋼部材で構成される住宅における縦枠材の構造と、縦枠材の固定装置に関するものである。ここでスチールハウスとは、板厚０．４ｍｍ以上、２．３ｍｍ未満の薄板軽量形鋼により構成される鋼構造建築物と定義する。
The present invention relates to a structure of a vertical frame member in a house composed of a thin and light steel member such as a steel house, and a vertical frame member fixing device. Here, the steel house is defined as a steel structure building composed of a thin lightweight steel having a thickness of 0.4 mm or more and less than 2.3 mm.

前記の建築用枠材は、薄鋼板をロールフォーミングにより成形して溝形、リップ付き溝形、ボックス形等の断面形状とし、巾寸法なども所定の使用形態に合わせて成形するもので、施工するときは、一本物の部材で使用し、又は複数本の部材をドリルねじで接合した組立部材として使用し、これら枠材同士をドリルねじ等で接合して建物の主架構を構築する。   The building frame material is formed by roll forming a thin steel plate to have a cross-sectional shape such as a groove shape, a groove shape with a lip, and a box shape, and the width dimension is also formed in accordance with a predetermined use form. When doing so, it is used as a single member or as an assembly member in which a plurality of members are joined with a drill screw, and these frame members are joined together with a drill screw or the like to construct the main frame of the building.

前記各種溝形鋼を組み合わせて構成する枠材の断面形状は各種あるが、使用箇所により断面形状が制限されることがある。例えば、スチールハウス等の建物における出入口や窓などの開口部の両脇に設けられる縦枠材の開口部側は、まぐさを取付ける関係上、平面であることが必要である。   There are various cross-sectional shapes of the frame material configured by combining the various groove steels, but the cross-sectional shape may be limited depending on the place of use. For example, the opening part side of the vertical frame member provided on both sides of the opening part such as the doorway and the window in a building such as a steel house needs to be a plane in terms of attaching a lintel.

図３で説明すると、開口部１の両脇に配置される縦枠材２には、一般的な縦枠材の機能の他に、開口部１の上部に配置される、まぐさ１２を固定するという、２つの機能が要求される。すなわち、開口部１の上部には、開口部上枠材４の上部に、まぐさ１２と呼ばれる部材が配置され、このまぐさ１２の両端部はまぐさ受け材１３を介して、開口部１の両脇に配置される縦枠材２に接合されることになる。そのため前記開口部両脇の縦枠材２の開口部１に面する辺には、まぐさ受け材１３を接合できる構成にする必要がある。   Explaining with FIG. 3, the vertical frame member 2 disposed on both sides of the opening 1 is fixed with a lintel 12 disposed on the upper portion of the opening 1 in addition to the function of a general vertical frame member. Two functions are required. In other words, a member called a lintel 12 is disposed above the opening upper frame member 4 at the top of the opening 1, and both ends of the lintel 12 are connected to the opening 1 via the lintel receiving member 13. It joins to the vertical frame material 2 arrange | positioned on both sides. Therefore, it is necessary to make it the structure which can join the lintel receiving material 13 to the edge | side which faces the opening part 1 of the vertical frame material 2 of the said opening part both sides.

さらに説明すると、下枠材５から複数の縦枠材２が所定の間隔をあけて立ち上がっており、各縦枠材２の上端は上枠材６に結合されており、下枠材５と縦枠材２と上枠材６で構成される壁枠材に構造用合板等の面材１０をドリルねじ８で固着して構成されている。   More specifically, a plurality of vertical frame members 2 rise from the lower frame member 5 at a predetermined interval, and the upper ends of the vertical frame members 2 are coupled to the upper frame member 6, and A wall material composed of the frame material 2 and the upper frame material 6 is fixed to a face material 10 such as a structural plywood with a drill screw 8.

開口部１の両側に配置される縦枠材２は、図４、図５に示すように２本のリップ付き溝形鋼２ａ、２ｂのウエブ２０をドリルねじで８で締結してなる組立てＨ形鋼が主に用いられる。縦枠材２は、２本のリップ溝付き形鋼２ａ、２ｂで十分軸力強度がある場合でも、まぐさ１２を取り付ける、まぐさ受け材１３を受けるための、軽溝形鋼からなる、かぶせ材１４が接合されている。   As shown in FIGS. 4 and 5, the vertical frame member 2 arranged on both sides of the opening 1 is an assembly H formed by fastening the webs 20 of the two lip-shaped channel steels 2 a and 2 b with a drill screw 8. Shape steel is mainly used. The vertical frame member 2 is made of light grooved steel for attaching the lintel 12 and receiving the lintel receiving material 13 even when the two lip grooved structural steels 2a and 2b have sufficient axial force strength. The covering material 14 is joined.

そして、縦枠材２における開口部側のリップ付き溝形鋼２ａにかぶせ材１４がドリルねじ８で固着され、かぶせ材１４にまぐさ受け材１３がドリルねじ８で固着され、まぐさ受け材１３に、まぐさ１２がドリルねじ８で取付けられて開口部における、まぐさ接合構造が構築される。まぐさ１２は、所定厚で所定寸法のパネル状である。   Then, the covering material 14 is fixed to the grooved steel 2a with the lip on the opening side in the vertical frame material 2 by the drill screw 8, and the lintel receiving material 13 is fixed to the covering material 14 by the drill screw 8, and the lintel receiving material. 13, the lintel 12 is attached with the drill screw 8 to construct the lintel junction structure in the opening. The lintel 12 is a panel shape having a predetermined thickness and a predetermined dimension.

前述の通り、開口部１の両脇の縦枠材２には、開口部側に位置するリップ付き溝形鋼２ａに、まぐさ受け材１３を取り付けるための、もう１本の軽溝形鋼からなる、かぶせ材１４を接合しているのが現状である。   As described above, in the vertical frame member 2 on both sides of the opening 1, another light grooved steel for attaching the lintel receiving member 13 to the grooved steel 2 a with a lip located on the opening side. It is the present condition that the covering material 14 which consists of is joined.

また、薄板軽量溝形鋼からなる下枠材５は、開口部を上向きにして基礎１５に設置されており、縦枠材２は、下枠材５のウエブ内面から立ち上がっていて、縦枠材２と下枠材５および基礎１５とはホールダウン金物１６にて結合されている。   In addition, the lower frame member 5 made of a thin and lightweight channel steel is installed on the base 15 with the opening facing upward, and the vertical frame member 2 stands up from the inner surface of the web of the lower frame member 5, and the vertical frame member 5 2, the lower frame member 5, and the foundation 15 are joined by a hole-down hardware 16.

ホールダウン金物１６は、水平部１７と立ち上がり部１８を補強板１９で補強して構成されている。このホールダウン金物１６は、開口部１と反対側のリップ付き溝形鋼２ｂの溝部に配置し、かつ、そのウエブ２０にホールダウン金物１６の立ち上がり部１８を当てがい、その当接部にドリルねじ８を打設して両部材を接合している。   The hole-down hardware 16 is configured by reinforcing a horizontal portion 17 and a rising portion 18 with a reinforcing plate 19. The hole-down hardware 16 is disposed in the groove portion of the grooved steel 2b with the lip opposite to the opening 1, and the rising portion 18 of the hole-down hardware 16 is applied to the web 20 and a drill is applied to the contact portion. Both members are joined by driving a screw 8.

また、ホールダウン金物１６の水平部１７は下枠材５のウエブ５ａに載置し、基礎１５に埋設されたアンカーボルト２１の上方突出部を前記水平部１７とウエブ５ａのボルト挿通孔２２を挿通させたうえ、その突出先端のねじ部にナット２３を締結する。これによりホールダウン金物１６介して縦枠材２を基礎１５に固定できる。   Further, the horizontal portion 17 of the hole-down hardware 16 is placed on the web 5a of the lower frame member 5, and the upward projecting portion of the anchor bolt 21 embedded in the foundation 15 is connected to the horizontal portion 17 and the bolt insertion hole 22 of the web 5a. After being inserted, the nut 23 is fastened to the threaded portion at the protruding tip. Thereby, the vertical frame member 2 can be fixed to the foundation 15 through the hole-down hardware 16.

前記のように、開口部１の両側に位置する縦枠材２の開口部側には、溝形鋼からなる、かぶせ材１４が取付けられるが、このかぶせ材１４の上下端は、上下枠材５、６のフランジ２４と干渉するため、縦枠材２におけるリップ付き溝形鋼２ａ、２ｂよりも短く設けられる。したがって、縦枠材２における力の伝達経路として、かぶせ材１４は上下枠材５、６から切り離されており、上下方向に作用する軸力に抵抗できず、軸力材として強度向上には寄与していない。   As described above, the covering member 14 made of channel steel is attached to the opening portion side of the vertical frame member 2 located on both sides of the opening portion 1. Since it interferes with the flanges 24 of 5 and 6, it is provided shorter than the grooved steels 2a and 2b with lips in the vertical frame member 2. Accordingly, the covering member 14 is separated from the upper and lower frame members 5 and 6 as a force transmission path in the vertical frame member 2 and cannot resist the axial force acting in the vertical direction, and contributes to improving the strength as an axial force member. Not done.

このため、図５の縦枠材２では、リップ付き溝形鋼２ａ、２ｂを背中合わせにした枠材としての軸力強度しか期待できず、これは次に説明する角形鋼（ボックス断面形鋼）に比べて強度的に劣ることである。したがって、開口部１両脇に設ける縦枠材２としてはボックス断面が望ましい。また、角形鋼は、４辺がウエブ面であるので、まぐさ受け材を取付ける上で具合がよく、図４、図５における、かぶせ材１４も必要としない。   For this reason, in the vertical frame member 2 of FIG. 5, only the axial force strength as a frame member in which the grooved steels 2a and 2b with lips are back to back can be expected. This is a square steel (box section steel) described below. It is inferior in strength compared to. Therefore, a box cross section is desirable as the vertical frame member 2 provided on both sides of the opening 1. Further, since the square steel has a web surface on four sides, it is good for attaching the lintel receiving material, and the covering material 14 in FIGS. 4 and 5 is not required.

このため、窓あるいは扉などの開口部の両脇の縦枠材は、角形鋼で構成することがあり、その代表例が、薄板軽量形鋼造建築物設計の手引き（国土交通省国土技術政策綜合研究所および独立行政法人建築研究所監修、社団法人日本鉄鋼連盟編集、技報堂出版、２００２年６月２５日）に示されるものである。この従来形態としては、図６（ａ）に示すような組立ボックス断面の縦枠材２、図６（ｂ）に示すような角形鋼からなる縦枠材２が使用される例がある。   For this reason, the vertical frame material on both sides of openings such as windows or doors may be made of square steel, a typical example of which is a guide for designing thin, lightweight steel structures (Ministry of Land, Infrastructure, Transport and Tourism Supervised by Sogo Research Institute and Architectural Research Institute, edited by Japan Iron and Steel Federation, Gihodo Publishing, June 25, 2002). As this conventional form, there is an example in which a vertical frame member 2 having an assembly box cross section as shown in FIG. 6A and a vertical frame member 2 made of square steel as shown in FIG. 6B are used.

図に示す例では、リップ付き溝形鋼２ａ、２ｂを向かい合わせてリップ２５同士を突き合わせ、両リップ付き溝形鋼２ａ、２ｂのフランジ２４に跨って接合プレート２６を当てがい、その当接部にドリルねじ８を打設して両リップ付き溝形鋼２ａ、２ｂを一体化することでボックス断面の縦枠材２を構成するものである。図６（ｅ）は、圧延成形や曲げ加工により形成した角形鋼からなる縦枠材２を示している。   In the example shown in the figure, the lip-shaped channel steels 2a, 2b are faced to face each other, the lips 25 are butted together, and the joining plate 26 is applied across the flanges 24 of the both lip-shaped channel steels 2a, 2b. A vertical frame member 2 having a box cross section is formed by placing a drill screw 8 on the two and integrating the lip-shaped channel steels 2a and 2b. FIG. 6E shows a vertical frame 2 made of square steel formed by rolling or bending.

発明が解決しようとする問題点は、次のとおりである。   The problems to be solved by the invention are as follows.

（１）最も一般的に用いられている図４、図５に示す縦枠材２では、かぶせ材１４を含めて３本の溝形鋼をドリルねじ８で接合する必要が生じ、組み立て手間や組み立てコストが問題となる。 (1) In the vertical frame member 2 shown in FIGS. 4 and 5 that is most commonly used, it is necessary to join three channel steels including the covering member 14 with the drill screw 8, Assembly cost is a problem.

また、縦枠材２の上方および下方には、上下枠材が配置されることになるが、かぶせ材１４の上下端部は、その上下枠材のフランジと干渉するため、図に示すように縦枠材２よりも短くなっており、このため特に軸力に対する設計については、形鋼が３本あるにも拘わらず、構造的には２本の形鋼として見なさなければならないという効率の悪い部材配置となっている。   In addition, the upper and lower frame members are arranged above and below the vertical frame member 2, but the upper and lower ends of the covering member 14 interfere with the flanges of the upper and lower frame members, so as shown in the figure. It is shorter than the vertical frame member 2, and therefore, especially for the design with respect to the axial force, although there are three shape steels, it is structurally inefficient that it must be regarded as two shape steels. It becomes member arrangement.

（２）（１）に示した欠点を補うために、図６（ｂ）に示すボックス断面の縦枠材２や図６（ｃ）に示すボックス断面の縦枠材２が提案された。図６（ｂ）に示す縦枠材２では、組み立て手間やコストにかかる問題が完全に解消されるわけではなく、また、図に示すような接合用のプレート２６が別途に必要になるものの、鋼材だけで、まぐさを受けることができ、構造的な効率は向上したといえる。さらに図６（ｃ）に示す縦枠材２を用いれば、組み立て手間をも無くすことができる。 (2) In order to compensate for the drawbacks shown in (1), a vertical frame member 2 having a box cross section shown in FIG. 6B and a vertical frame member 2 having a box cross section shown in FIG. 6C have been proposed. In the vertical frame material 2 shown in FIG. 6 (b), the problem of assembling labor and cost is not completely solved, and a joining plate 26 as shown in the figure is separately required. It can be said that the tickling can be received only with steel, and the structural efficiency has improved. Furthermore, if the vertical frame member 2 shown in FIG. 6C is used, it is possible to eliminate assembling work.

しかし、これらのボックス断面の縦枠材２を用いると、新たな問題が生じる。すなわち、ホールダウン金物１６の縦枠材２への取付位置は、当該縦枠材の中心部（断面重心）近い方が望ましく、断面重心からの距離が大きくなると縦枠材２に付加曲げが生じることになる。   However, a new problem arises when these box cross-section vertical frame members 2 are used. That is, it is desirable that the mounting position of the hole-down hardware 16 on the vertical frame member 2 is closer to the center part (cross-sectional center of gravity) of the vertical frame member, and additional bending occurs in the vertical frame member 2 as the distance from the cross-sectional center of gravity increases. It will be.

図６（ｂ）、（ｃ）に示す閉鎖型の縦枠材２を使用する場合のホールダウン金物１６は、図に示すように形鋼断面幅の半分に相当する距離分だけ、断面重心からずれた位置に接合されることになる。その結果、縦枠材２に作用する付加曲げの分補強のため板厚を割増しなければならない場合もあり、閉鎖型の縦枠材２の使用は構造上、経済上ベストな解決策とはいえない。   When the closed vertical frame member 2 shown in FIGS. 6 (b) and 6 (c) is used, the hole-down hardware 16 is separated from the cross-sectional center of gravity by a distance corresponding to half of the cross-section width of the section steel as shown in the figure. It will be joined at a shifted position. As a result, the plate thickness may have to be increased to reinforce the additional bending acting on the vertical frame member 2, and the use of the closed vertical frame member 2 is the best solution in terms of structure and economy. Absent.

（３）図６（ｃ）に示す角形鋼製の縦枠材２では、形鋼同士のドリルねじ接合は発生しなくなる。しかし、角形鋼を形成するためには、リップ溝形鋼や軽溝形鋼を形成するよりも大がかりな設備（溶接設備やカシメ設備等閉鎖断面化するための接合設備）が必要となるため、形鋼の製造費用は大きくなる。 (3) In the vertical frame member 2 made of square steel shown in FIG. 6C, drill screw joining between the shaped steels does not occur. However, in order to form square steel, larger equipment (joining equipment for making a closed cross section such as welding equipment and caulking equipment) is required compared to forming lip groove steel and light groove steel, The manufacturing cost of the shape steel increases.

前記の問題点に鑑みて本発明は、ボックス断面の形鋼に相当する機能を有する縦枠材を構成することによりまぐさ受け材を不要とする有利性を実現し、なおかつ、従来の角形鋼で縦枠材を製作することに伴う、製作面での不合理性及び、ホールダウン金物の取付け位置の偏芯性の問題を解消したスチールハウス等の住宅用縦枠材を提供することを目的とする。   In view of the above problems, the present invention realizes the advantage of eliminating the need for a lintel support material by constituting a vertical frame material having a function corresponding to the shape steel of a box cross section, and also a conventional square steel The purpose is to provide a vertical frame material for a house such as a steel house which has solved the problem of unreasonableness in manufacturing and the eccentricity of the mounting position of the hole-down hardware due to the production of the vertical frame material at And

前記の目的を達成するため、本発明は、次のように構成する。   In order to achieve the above object, the present invention is configured as follows.

第１の発明は、複数の薄板軽量溝形鋼からなる縦枠材であって、前記縦枠材は、薄板軽量溝形鋼又はリップ付き薄板軽量溝形鋼からなるフランジ広幅溝形鋼と、その内部に収容した薄板軽量溝形鋼又は、リップ付き薄板軽量溝形鋼からなるフランジ狭幅溝形鋼とを組み合わせることで、フランジ狭幅溝形鋼のウエブをフランジ広幅溝形鋼内の中央部に位置させたうえ内外両溝形鋼を固着したことを特徴とする。   1st invention is a vertical frame material which consists of a plurality of thin plate lightweight channel steel, and the vertical frame material is a flange wide channel steel made of a thin plate lightweight channel steel or a thin plate lightweight channel steel with a lip, By combining the thin lightweight grooved steel housed in the inside or the flanged narrow grooved steel made of the thin lightweight grooved steel with a lip, the flanged narrow grooved web is placed in the center of the flanged wide grooved steel. It is characterized in that both the inner and outer channel steels are fixed in place.

第２の発明は、第１の発明において、前記フランジ狭幅溝形鋼のフランジ長さは、フランジ広幅溝形鋼のフランジ長さの略２分の１であり、フランジ狭幅溝形鋼のフランジ先端部がフランジ広幅溝形鋼のウエブ内面に当接するように収容配置されており、両溝形鋼のフランジ同士が、またはフランジ広幅溝形鋼のウエブとフランジ狭幅溝形鋼のリップが、ドリルねじ、くぎ、ボルト、リベット、溶接、かしめ、接着等の接合手段により接合されていることを特徴とする。   According to a second invention, in the first invention, the flange length of the flange narrow groove steel is approximately one half of the flange length of the flange wide groove steel. The flange tip is housed and arranged so that it abuts against the inner surface of the flange wide channel steel, and the flanges of both channel steels or the flange wide channel steel and the flange narrow channel lip , Drill screws, nails, bolts, rivets, welding, caulking, bonding, and the like.

第３の発明は、前記フランジ狭幅溝形鋼のフランジ長さは、フランジ広幅溝形鋼のフランジ長さの略２分の１であり、フランジ狭幅溝形鋼のフランジ先端部がフランジ広幅溝形鋼のリップ内面に当接するように収容配置されており、両溝形鋼のフランジ同士が、または両溝形鋼のリップ同士が、ドリルねじ、くぎ、ボルト、リベット、溶接、かしめ、接着等の接合手段により接合されていることを特徴とする。 According to a third aspect of the present invention, the flange length of the flange narrow groove steel is approximately one half of the flange length of the flange wide groove steel, and the flange tip of the flange narrow groove steel has a flange wide width. is housed disposed to abut against the lip inner face of the channel steel, the flanges of both the channel steel is, or lip of both the channel steel is, drill screw, nail, bolt, rivet, welding, caulking, adhesive It is characterized by being joined by a joining means such as.

第４の発明は、基礎に配置した薄板軽量溝形鋼からなる下枠材のウエブ内面から第１〜第３の発明に記載の縦枠材を立設し、当該縦枠材中央部に位置するフランジ狭幅溝形鋼のウエブに、ホールダウン金物における立ち上がり部を当接したうえ、該当接部をドリルねじにより接合し、ホールダウン金物における水平部を前記下枠材のウエブに載置し、前記基礎から立ち上がるアンカーボルトを下枠材のウエブとホールダウン金物の水平部のボルト挿通孔に挿通させたうえ、その突出したねじ部にナットを締結したことを特徴とする。   4th invention erected the vertical frame material as described in the 1st-3rd invention from the web inner surface of the lower frame material which consists of a thin plate lightweight channel steel arrange | positioned in the foundation, and is located in the said vertical frame material center part. The rising part of the hole-down hardware is brought into contact with the web of the flanged narrow grooved steel, and the corresponding contact part is joined with a drill screw, and the horizontal part of the hole-down metal is placed on the web of the lower frame material. The anchor bolt rising from the foundation is inserted through the web of the lower frame member and the bolt insertion hole of the horizontal portion of the hole-down hardware, and the nut is fastened to the protruding screw portion.

第５の発明は、第４の発明において、前記縦枠材を開口部の両脇に立設し、当該縦枠材の開口部側に位置するフランジ広幅溝形鋼のウエブに溝形鋼からなる、まぐさ受け材を取り付けて、該まぐさ受け材に、まぐさの両端部をドリルねじ等で固着したことを特徴とする。
According to a fifth invention, in the fourth invention, the vertical frame member is erected on both sides of the opening, and the flange wide groove steel web positioned on the opening side of the vertical frame member is formed from the groove steel. The lintel receiving material is attached, and both ends of the lintel are fixed to the lintel receiving material with a drill screw or the like.

本発明によると、フランジ広幅溝形鋼の内部にフランジ狭幅溝形鋼を収容して両溝形鋼を組み合わせて縦枠材を構成するので、（１）縦枠材の断面の一部に箱形断面部が形成されていることで曲げ強度が向上し、かつ、全断面部が軸力抵抗部材として機能することで、軸方向にも強度に富む縦枠材を構成できる。   According to the present invention, the flange narrow groove steel is accommodated in the flange wide groove steel, and the vertical frame member is configured by combining both groove steels. (1) In a part of the cross section of the vertical frame member By forming the box-shaped cross-section, the bending strength is improved, and the entire cross-section functions as an axial force resistance member, so that a vertical frame material rich in strength in the axial direction can be configured.

（２）縦枠材の中央部にウエブを位置させており、縦枠材を基礎構造及び天井スラブに固定するためのホールダウン金物の立ち上がり部を、前記ウエブに接合できるので、ホールダウン金物の縦枠材への取付位置は、縦枠材の中心部（断面重心）近くであるので、縦枠材に付加曲げが生じることが少ない。 (2) Since the web is positioned at the center of the vertical frame member and the rising part of the hole down hardware for fixing the vertical frame member to the foundation structure and the ceiling slab can be joined to the web, Since the attachment position to the vertical frame member is close to the center portion (cross-sectional center of gravity) of the vertical frame member, additional bending is less likely to occur in the vertical frame member.

（３）縦枠材はフランジ広幅溝形鋼とフランジ狭幅溝形鋼の組み合わせから構成するに拘わらず、内外の溝形鋼を貫通するようにドリルねじ等を打設することで構成でき、従来の接合板などを必要とせず、組み立て手間や組み立てコストを低減できる。 (3) Regardless of whether the vertical frame material is composed of a combination of a flange wide groove steel and a flange narrow groove steel, it can be configured by driving a drill screw or the like so as to penetrate the inner and outer groove steel, A conventional joining plate or the like is not required, and assembly labor and cost can be reduced.

（４）縦枠材におけるフランジ広幅溝形鋼のウエブ面を壁の開口部側に面するように配置して立設することで、まぐさ受け材をウエブに取り付けることができ、従来のかぶせ材が不要である。
(4) By placing the web surface of the flange wide channel steel in the vertical frame material so that it faces the opening side of the wall, the lintel support material can be attached to the web, and the conventional covering No material is required.
