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、まぐさ等横架材接合構造に関する。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 for joining horizontal members such as lintels in a house composed of a thin, lightweight steel member such as a steel house. 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.

前記の薄板軽量鋼部材は、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等で接合した組立部材として使用し、これら部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 thin lightweight steel member is formed by roll forming a thin steel plate into a cross-sectional shape such as a groove shape, a groove shape with a lip, a box shape, etc., 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 or the like, and these members are joined together with a drill screw or the like to construct the main frame of the building.

スチールハウス等の主架構の構築にあたっては、鉛直部材となる縦枠材に、上下枠材、梁、まぐさ等の横架材を、ドリルねじ等で接合することになる。縦枠材の側面に横架材を接合する場合では、いずれも技術的には同様な接合形態となるといえる。ここでは出入口や窓などの開口部を用いて説明する。   When constructing a main frame such as a steel house, horizontal frames such as upper and lower frame members, beams, and lintels are joined to vertical frame members serving as vertical members by drill screws or the like. In the case where the horizontal member is joined to the side surface of the vertical frame member, it can be said that both are technically similar in joining form. Here, description will be made using openings such as doorways and windows.

スチールハウス等に形成される出入口や窓には縦枠材が存在しないことから、屋根等の上階からの鉛直荷重を支える支持柱がなく開口部の部位は強度的に弱くなる。   Since there is no vertical frame material at the doorway or window formed in a steel house or the like, there is no support column that supports the vertical load from the upper floor such as the roof, and the site of the opening becomes weak in strength.

このため、窓あるいは扉などの開口部の上部には、まぐさ等の横架材が配置され、このまぐさ等横架材と開口部両脇の縦枠材との接合部は、所定の強度を確保できる構造とされている。その代表例が、薄板軽量形鋼造建築物設計の手引きのｐ３１（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り、この従来形態は、図５〜図７に示すような構成になっている。   For this reason, a horizontal member such as a lintel is arranged on the upper part of the opening such as a window or a door, and the joint between the horizontal member such as the lintel and the vertical frame member on both sides of the opening is a predetermined part. It is structured to ensure strength. A typical example is p31 of the guide for designing thin steel lightweight steel structures (supervised by the Ministry of Land, Infrastructure, Transport and Tourism, National Institute for Land and Infrastructure Policy Policy and Independent Administrative Institute, Institute of Building Research, Japan Iron and Steel Federation, Gihodo Publishing, June 2002 25th), and this conventional configuration is configured as shown in FIGS.

図５において、下枠材１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３に結合されており、この下枠材１と縦枠材２と上枠材３で構成される壁枠材に構造用合板等の面材４をドリルねじ５で固着して構成されている。   In FIG. 5, a plurality of vertical frame members 2 rise from the lower frame member 1 with a predetermined interval, and the upper ends of the vertical frame members 2 are coupled to the upper frame member 3. A face material 4 such as a structural plywood is fixed to a wall frame material composed of a vertical frame material 2 and an upper frame material 3 with a drill screw 5.

出入口や窓などの開口部６において、開口部両脇に所定の間隔をおいて配置される縦枠材２の上部の間は、開口部上枠材７で結合され、縦枠材２の下部の間は開口部下枠材８で結合され、これらで囲まれる内側が開口部６とされている。   In the opening 6 such as a doorway or a window, the upper part of the vertical frame member 2 arranged at a predetermined interval on both sides of the opening is coupled by the upper frame member 7 of the opening, and the lower part of the vertical frame member 2 Are connected by an opening lower frame member 8, and the inside surrounded by these is an opening 6.

開口部６の上部には、まぐさ等横架材１０が配置される。まぐさ等横架材１０には、種々の構成があるが、図示の従来例のまぐさ等横架材１０は、所定の厚みを有し、所定寸法の組立部材として、または単材として構成される。   A horizontal member 10 such as a lintel is disposed on the upper portion of the opening 6. The lintel horizontal member 10 has various configurations. The illustrated conventional lintel horizontal member 10 has a predetermined thickness and is configured as an assembly member having a predetermined dimension or as a single member. Is done.

開口部６の両側に配置される縦枠材２は、図６、図７に示すような２本のリップ付き溝形鋼２ａ、２ｂのウエブ１１をドリルねじで５で締結してなる組立てＨ形鋼が主に用いられる。さらに開口部両脇の縦枠材２にあっては、２本のリップ付き溝形鋼２ａ、２ｂで強度が十分な場合でも、開口部側のリップ付き溝形鋼２ａには、軽量形鋼からなる、かぶせ材１２が取付けられ、このかぶせ材１２に、まぐさ等横架材１０の両端縁を受けるための軽溝形鋼からなる、まぐさ等横架材受け材１３が接合される。そして、まぐさ等横架材受け材１３に、まぐさ等横架材１０がドリルねじ５で取付けられて開口部上側の、まぐさ等横架材の接合構造が構築されている。   The vertical frame member 2 arranged on both sides of the opening 6 is an assembly H formed by fastening two webs 11 of lip-shaped channel steels 2a and 2b with a drill screw 5 as shown in FIGS. Shape steel is mainly used. Further, in the case of the vertical frame member 2 on both sides of the opening, even if the strength is sufficient with the two lip-shaped grooved steels 2a and 2b, the lip-shaped grooved steel 2a on the opening side has a light weight shaped steel. The covering member 12 is attached, and the covering member 12 is joined to the covering member 12 made of light grooved steel for receiving both end edges of the covering member 10 such as the lintel. . Then, the lintel horizontal member 10 is attached to the lintel horizontal material receiving member 13 with the drill screw 5 to construct a joint structure of the lintel horizontal material on the upper side of the opening.

前記の通り、開口部６両脇の縦枠材２には、２本のリップ付き溝形鋼２ａ、２ｂで強度が十分な場合でも、まぐさ等横架材受け材１３を取り付けるために、もう１本の軽溝形鋼を、かぶせ材１２として縦枠材２の開口部６に面する側に接合しているのが現状である。   As described above, the vertical frame member 2 on both sides of the opening 6 has the two lip-shaped grooved steels 2a and 2b to attach the horizontal member receiving member 13 such as a lintel even when the strength is sufficient. At present, another light groove steel is joined to the side facing the opening 6 of the vertical frame member 2 as the covering member 12.

以下に、図７（ａ）〜（ｄ）に従来技術における施工手順を説明する。   Below, the construction procedure in a prior art is demonstrated to Fig.7 (a)-(d).

解決しようとする課題は、従来、主に住宅の壁に設けられる開口部等において、まぐさ等横架材受け材を介して、まぐさ等横架材を開口部両脇の縦枠材に接合するに際し、まぐさ等横架材受け材を縦枠材に取り付けるために溝形鋼からなる、かぶせ材を必要とした。このかぶせ材を設置する施工コストおよび部材数が増加するので、本発明ではこの点を改良し、かぶせ材の設置を不要とし、施工コストおよび部材数削減を実現し、経済的な設計を可能とすることである。   Conventionally, the problem to be solved is that the vertical frame material on both sides of the opening is used mainly in the opening provided on the wall of the house, etc. When joining, a covering material made of channel steel was required to attach the horizontal material receiving material such as the lintel to the vertical frame material. Since the construction cost and the number of members for installing the cover material increase, the present invention improves this point, makes the installation of the cover material unnecessary, reduces the construction cost and the number of members, and enables an economical design. It is to be.

前記の課題を解決するため、本発明は次のように構成する。   In order to solve the above problems, the present invention is configured as follows.

第６の発明は、第１又は第２の発明において、まぐさ横架材取付け金物の両側部は拡開側にバネ付勢されていて、両裾部が縦枠材の開口部側のリップ付き溝形鋼のリップに係合可能に設けられていることを特徴とする。 A sixth invention is the first or second aspect, mug of both side portions of the horizontal member mounting hardware is being spring biased to spreading side, the opening side of the both skirt portions vertical frame member lip It is provided so that it can be engaged with a lip of a grooved steel.

本発明に係る、まぐさ等横架材受け金物は、従来の、かぶせ材、まぐさ等横架材受け材の両者の機能を併せ持つ断面形状を有する形鋼材からなり、凸形状を基本としており、凸形部分が、縦枠材における開口部側に位置するリップ付き溝形鋼の溝部に嵌められ、凸形先端部がウエブに当接したうえドリルねじ等で接合するため、従来の、かぶせ材を設置する必要がなく、施工コストおよび部材数削減が実現され、経済的な設計が可能になる。   The horizontal material receiving material such as a lintel according to the present invention is made of a shaped steel material having a cross-sectional shape having the functions of both a conventional covering material and a horizontal material receiving material such as a lintel, and is based on a convex shape. Since the convex part is fitted in the groove part of the lip-shaped channel steel located on the opening side of the vertical frame material, the convex tip part contacts the web and is joined with a drill screw or the like. There is no need to install materials, construction costs and the number of members are reduced, and economical design is possible.

以下、本発明の実施形態を図を参照して説明する。なお、従来例と同一の要素には同一符号を付して重複説明を省略する。   Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the element same as a prior art example, and duplication description is abbreviate | omitted.

図１、図２は実施形態１を示す。各図において、開口部６の両側辺を構成する各縦枠材２は、２本のリップ付き溝形鋼２ａ、２ｂを背中合わせに配置し、ウエブ１１同士をドリルねじ５で接合して構成すること、縦枠材２の上下端を上枠材３と下枠材１に接合すること、まぐさ１０が、所定寸法の組立部材として、または単材として構成される点は、従来と同じである。   1 and 2 show the first embodiment. In each figure, each vertical frame member 2 constituting both sides of the opening 6 is configured by arranging two lip-shaped channel steels 2a and 2b back to back and joining the webs 11 with a drill screw 5. In other words, the upper and lower ends of the vertical frame member 2 are joined to the upper frame member 3 and the lower frame member 1, and the lintel 10 is configured as an assembly member of a predetermined size or as a single member. is there.

開口部６の上部に設ける、まぐさ等横架材１０の両側縁を、まぐさ等横架材受け金物１７を介して縦枠材２における、開口部６側に位置するリップ付き溝形鋼２ａに接合する点が本発明の主要素である。   Ribbed steel with lips located on the side of the opening 6 in the vertical frame member 2 with both side edges of the lintel such as the lintel 10 provided at the top of the opening 6 via the lintel horizontal material receiving metal 17 The point joined to 2a is the main element of the present invention.

さらに詳細に説明すると、まぐさ等横架材取付け金物１７は、鋼板を凸形状に曲げ形成することによって構成し、両裾部１８と先端部１９を有し、両裾部１８と先端部１９の間を両側部２０とする。   More specifically, the horizontal member mounting hardware 17 such as a lintel is formed by bending a steel plate into a convex shape, and has both hem portions 18 and tip portions 19, and both hem portions 18 and tip portions 19. Between the two sides 20.

実施形態１のまぐさ等横架材取付け金物１７においては、その凸形状部を開口部６側に位置するリップ付き溝形鋼２ａの溝部に嵌合し、かつ、フラットな先端部１９を、前記リップ付き溝形鋼２ａのウエブ１１に接合し、この接合部にドリルねじ５を打設し、さらに、両裾部１８とリップ付き溝形鋼２ａのリップ２１との当接部にドリルねじ５を打設することで、まぐさ取付け金物１７を縦枠材２に固着している。   In the horizontal member mounting hardware 17 such as the lintel of Embodiment 1, the convex portion is fitted into the groove portion of the grooved steel 2a with a lip located on the opening 6 side, and the flat distal end portion 19 is It joins to the web 11 of the grooved steel 2a with the lip, and a drill screw 5 is driven into this joint, and further, a drill screw is brought into contact with the hem part 18 and the lip 21 of the grooved steel 2a with lip. By placing 5, the lintel mounting hardware 17 is fixed to the vertical frame member 2.

こうして縦枠材２における開口部６側のリップ付き溝形鋼２ａに、まぐさ等横架材受け金物１７を固着した後、当該まぐさ等横架材受け金物１７の両端部２２で、まぐさ等横架材１０の両側縁を挟み、この挟持部にドリルねじ５を打設することで、まぐさ等横架材１０とまぐさ等横架材受け金物１７を固着する。   In this way, after attaching the horizontal member receiving material 17 such as the lintel to the grooved steel 2a with the lip on the opening 6 side in the vertical frame member 2, the magnifying glass is applied to both ends 22 of the horizontal material receiving member 17 such as the lintel. By sandwiching both side edges of the horizontal member 10 and placing the drill screw 5 in the holding portion, the horizontal member 10 and the horizontal member receiving piece 17 such as the lintel are fixed.

こうして実施形態１に係る凸形状のまぐさ等横架材受け金物１７は、先端部を縦枠材２に接合すると共に、両端部で、まぐさ等横架材１０を固着する。つまり、まぐさ等横架材受け金物１７は従来のかぶせ材と、まぐさ等横架材受け材の両者の機能を併せ持つ断面形状を有する形鋼で構成されているから、従来のかぶせ材を設置する必要がなくなり、施工コストおよび部材数削減が実現され、経済的な設計が可能になる。   In this way, the convex support member 17 such as the lintels according to the first embodiment joins the tip portion to the vertical frame member 2 and fixes the cross member 10 such as the lintel at both ends. In other words, the horizontal support member 17 such as a lintel is made of a shape steel having a cross-sectional shape having both functions of a conventional cover material and a horizontal material support material such as a lintel. There is no need for installation, the construction cost and the number of members are reduced, and an economical design becomes possible.

図２を用いて、本発明の基本となる実施形態１の施工手順を説明する。
（１）リップ付き溝形鋼２ａ、２ｂの２本から構成される縦枠材２（組み立てＨ形鋼）を配置する。
（２）縦枠材２に本発明の″まぐさ等横架材受け金物″１７を接合する。
（３）″まぐさ等横架材受け金物″１７に、まぐさ等横架材１０を接合する。
前記から、本発明のまぐさ等横架材受け金物１７を用いることで、従来技術と比較して施工工程が１ステップ省かれていることが明確に分る。 The construction procedure of the first embodiment, which is the basis of the present invention, will be described with reference to FIG.
(1) A vertical frame member 2 (assembled H-section steel) composed of two lip-shaped channel steels 2a and 2b is disposed.
(2) The “frame support member 17” of the present invention is joined to the vertical frame member 2.
(3) The horizontal member 10 such as a lintel is joined to the “horizontal member receiving metal 17”.
From the above, it can be clearly seen that the use of the horizontal support member 17 such as the lintel of the present invention eliminates one step of the construction process compared to the prior art.

実施形態１に係るまぐさ等横架材受け金物１７は、縦枠材２に当てがう構造用合板等面材２３（図３以下で示す）を取付けるドリルねじ５がこの部位においては、まぐさ等横架材受け金物１７を貫通しない面材ドリルねじ非貫通型の例である。このドリルねじ非貫通型の例では、面材を接合するドリルねじの回転が、まぐさ受け金物１７によって拘束されないため、壁のせん断剛性は、後述の実施形態２に比べて低下するが、変形性能が良くなる。   The horizontal support member 17 such as a lintel according to the first embodiment is provided with a drill screw 5 for attaching a structural plywood surface member 23 (shown in FIG. 3 and the following) applied to the vertical frame member 2. This is an example of a face material drill screw non-penetrating type that does not penetrate the horizontal member 17. In this drill screw non-penetrating type, the rotation of the drill screw that joins the face materials is not constrained by the lintel bracket 17, so that the shear rigidity of the wall is lower than that in the second embodiment described later. Performance is improved.

つぎに、図３（ａ）を用いて、本発明の実施形態２として、面材ドリルねじ貫通型の、まぐさ受け金物１７の例について説明する。   Next, an example of a face material drill screw penetration type lintel receiving metal 17 will be described as Embodiment 2 of the present invention with reference to FIG.

実施形態２に係る、まぐさ等横架材受け金物１７の構成は、実施形態１と同じであるが、構造用合板等の面材２３を接合するためのドリルねじ５が、まぐさ等横架材受け金物１７の両側部２０を貫通している例である。この例では、面材２３を接合するドリルねじ５の回転をまぐさ等横架材受け金物１７が拘束するため、壁のせん断剛性が実施形態１に比べて向上する。なお、実施形態２では、まぐさ取付け金物１７の両裾部１８と、リップ付き溝形鋼２ａのリップ２１との当接部は、ドリルねじ５が打設されていない点が実施形態１と相異している。   The configuration of the horizontal support member 17 such as a lintel according to the second embodiment is the same as that of the first embodiment, but the drill screw 5 for joining the face material 23 such as a structural plywood is This is an example of penetrating both side portions 20 of the bridge receiving material 17. In this example, since the horizontal member receiving material 17 such as a lintel restrains the rotation of the drill screw 5 that joins the face material 23, the shear rigidity of the wall is improved as compared with the first embodiment. In Embodiment 2, the point where the drill screw 5 is not driven in the contact portion between both hem portions 18 of the lintel attachment hardware 17 and the lip 21 of the grooved steel 2a with lip is different from that in Embodiment 1. It is different.

図３（ｂ）は、本発明の実施形態３として、面材ドリルねじ非貫通型の、まぐさ等横架材受け金物１７の例を示す。   FIG.3 (b) shows the example of the horizontal material receiving metal object 17, such as a lintel, of face material drill screw non-penetrating type as Embodiment 3 of this invention.

実施形態３に係る、まぐさ等横架材受け金物１７の基本構成は、実施形態１、２と同じであるが、まぐさ等横架材受け金物１７の両側部２０を、中央部寄りに位置させており、構造用合板等の面材２３を縦枠２に接合するドリルねじ５が、まぐさ等横架材受け金物１７の両側部２０を貫通しない例である。この例では、ドリルねじ５により面材２３と縦枠材２が固着され、かつ、ドリルねじ５の回転が、まぐさ等横架材受け金物１７によって拘束されないため、壁のせん断剛性は、後述の実施形態２に比べて低下するが、変形性能が良くなる。   Although the basic configuration of the horizontal support member 17 such as the lintel according to the third embodiment is the same as that of the first and second embodiments, both side portions 20 of the horizontal support member 17 such as the lintel are closer to the center portion. This is an example in which the drill screw 5 that is positioned and joins the face material 23 such as a structural plywood to the vertical frame 2 does not penetrate the both side portions 20 of the horizontal member receiving hardware 17 such as a lintel. In this example, since the face member 23 and the vertical frame member 2 are fixed by the drill screw 5 and the rotation of the drill screw 5 is not restrained by the horizontal member 17 such as a lintel, the shear rigidity of the wall will be described later. However, the deformation performance is improved.

図４（ａ）は実施形態４として、面材ドリルねじ非貫通型の、まぐさ等横架材受け金物１７の例を示す。   FIG. 4A shows an example of a horizontal material receiving material 17 such as a lintel, which is a non-penetrating face material drill screw, as a fourth embodiment.

実施形態４に係る、まぐさ等横架材受け金物１７の基本構成は、先の各実施形態と同じであるが、まぐさ等横架材受け金物１７の両側部２０を、中央部寄りにＶ字状２０ａに曲げ形成することにより、構造用合板等の面材２３を接合するためのドリルねじ５が、まぐさ等横架材受け金物１７の両側部２０を貫通しない構成としている。この実施形態４によると、凸状の先端部１９の平面部を大きくし、縦枠材２のウエブ１１との接触面積を大きくできるので、当該接合部に打設するドリルねじ５の本数を多くしたい場合に効果がある。   The basic configuration of the horizontal support member 17 such as the lintel according to the fourth embodiment is the same as that of each of the previous embodiments, but the side portions 20 of the horizontal support member 17 such as the lintel are closer to the center portion. By bending it into a V-shape 20a, the drill screw 5 for joining the face material 23 such as a structural plywood does not penetrate the both side portions 20 of the horizontal member receiving object 17 such as a lintel. According to the fourth embodiment, since the flat surface portion of the convex tip portion 19 can be enlarged and the contact area of the vertical frame member 2 with the web 11 can be increased, the number of drill screws 5 to be placed on the joint portion is increased.
