Description

本発明は、建物の天井、壁及び床などに用いられる下地構造に関する。   The present invention relates to a base structure used for a ceiling, wall, floor, and the like of a building.

例えば、特許文献１には、主材（スタッド）と振れ止め材が格子状に接合された壁下地構造が記載されている。図８は、当該発明において、主材に振れ止め材を接合する場合を段階ごとに示した正面図であって、（ａ）は、挿入状態、（ｂ）は、拡開状態、（ｃ）は、接合状態を示した正面図である。   For example, Patent Document 1 describes a wall base structure in which a main material (stud) and a steady rest material are joined in a lattice shape. FIG. 8 is a front view showing the case where the steady rest material is joined to the main material for each stage in the invention, wherein (a) is an inserted state, (b) is an expanded state, and (c). These are the front views which showed the joining state.

図８（ａ）に示すように、下地構造１００に係る振れ止め材１０２は、下部が開放した断面略コの字型のチャンネル材であって、弾性変形可能なフランジ部１０６と、このフランジ部１０６の先端から内側に延出するリップ１０７と、リップ１０７の先端から立ち上げられた爪１０８とが設けられている（以下、リップ１０７と爪１０８を合わせて先端部１０９とする）。   As shown in FIG. 8A, the steadying material 102 according to the base structure 100 is a channel material having a substantially U-shaped cross-section with an open lower portion, and an elastically deformable flange portion 106 and the flange portion. A lip 107 extending inward from the tip of 106 and a claw 108 raised from the tip of the lip 107 are provided (hereinafter, the lip 107 and the claw 108 are collectively referred to as a tip portion 109).

一方、主材１０１は、振れ止め材１０２が挿通される開口部１０３と、この開口部１０３の底部から上方に突出する係合突起１０４と、開口部１０３の両側から内方に向って突出する凸部１０５とを有する。係合突起１０４は、曲部１０４ａと、開口部１０４の下端から立設された基軸部１０４ｂとを有する。曲部１０４ａの端部１０４ｃ，１０４ｃの距離は、爪１０８，１０８間の距離よりも若干長く形成されている。一方、基軸部１０４ｂの幅は、爪１０８，１０８間の距離と略同等に形成されている。   On the other hand, the main member 101 protrudes inward from both sides of the opening 103, an opening 103 through which the steadying member 102 is inserted, an engaging protrusion 104 protruding upward from the bottom of the opening 103, and the opening 103. And a convex portion 105. The engagement protrusion 104 has a curved portion 104 a and a base shaft portion 104 b that is erected from the lower end of the opening 104. The distance between the end portions 104c and 104c of the curved portion 104a is slightly longer than the distance between the claws 108 and 108. On the other hand, the width of the base shaft portion 104b is formed substantially equal to the distance between the claws 108 and 108.

主材１０１と振れ止め材１０２は、図８（ａ）乃至（ｃ）に示すように、振れ止め材１０２を開口部１０３の上部から下部に向けて押し込んで嵌め合わせることにより接合するものである。
より詳しくは、図８（ａ）に示すように、開口部１０３の上部に振れ止め材１０２を挿通させた後、振れ止め材１０２を開口部１０３の上部から下部に向けて移動させる。そして、図８（ｂ）に示すように、振れ止め材１０２の先端部１０９と係合突起１０４が当接した後、さらに押し込むと、係合突起１０４の曲部１０４ａに沿って先端部１０９，１０９が両外側に拡開される。そして、さらに押し込むと、図８（ｃ）に示すように、フランジ部１０６が弾性変形により元の形状に復元するため、先端部１０９が係合突起１０４の基軸部１０４ｂに当接されると共に、基端部１１０が凸部１０５に当接される。これにより、主材１０１と振れ止め材１０２は、垂直方向の移動及び横方向の移動が規制されるため、主材１０１と振れ止め材１０２を簡易に接合し、下地構造１００を構築することができる。 As shown in FIGS. 8A to 8C, the main material 101 and the steady rest material 102 are joined by pressing and fitting the steady rest material 102 from the upper part of the opening 103 toward the lower part. .
More specifically, as shown in FIG. 8A, after the anti-rest material 102 is inserted through the upper portion of the opening 103, the anti-static material 102 is moved from the upper portion of the opening 103 toward the lower portion. Then, as shown in FIG. 8 (b), when the leading end 109 of the steady rest member 102 and the engaging projection 104 come into contact with each other and then further pushed in, the leading end 109, along the curved portion 104a of the engaging projection 104, 109 is expanded on both outer sides. When further pushed in, as shown in FIG. 8C, the flange portion 106 is restored to its original shape by elastic deformation, so that the distal end portion 109 is brought into contact with the base shaft portion 104b of the engaging protrusion 104, and The base end portion 110 is brought into contact with the convex portion 105. Accordingly, since the main material 101 and the steadying material 102 are restricted from moving in the vertical direction and laterally, the main material 101 and the steadying material 102 can be simply joined to construct the base structure 100. it can.

特開２００２−１３８６０５号公報（図１〜図４）JP 2002-138605 A (FIGS. 1 to 4)

しかしながら、前記従来の発明は、開口部１０３を振れ止め材１０２の形状に応じて形成するため、主材１０１は、振れ止め材１０２の幅と両凸部１０５，１０５の幅以上の材料により構成する必要があった。そのため、小断面の（幅が細い）主材を使用する下地構造では、適用することができず、限られた構造にしか採用できないという問題点を有していた。また、主材１０１の幅寸法に対して、開口部１０３の形状を大きく形成する必要があったため、主材１０１の強度が低下するという問題点も有していた。また、従来の開口部１０３には、先端部１０９，１０９の拡開を可能とするために、間隙１１１が形成する必要があり、開口部１０３の形状が複雑で、その形成に手間がかかるという問題点を有していた。さらに、このような、主材１０１の強度の低下により、主材１０１と振れ止め材１０２との接合強度の低下も招来するという問題点を有していた。   However, since the conventional invention forms the opening 103 in accordance with the shape of the steady rest material 102, the main material 101 is made of a material having a width equal to or larger than the width of the steady rest material 102 and the widths of both convex portions 105 and 105. There was a need to do. Therefore, the base structure using a main material having a small cross section (thin width) cannot be applied and has a problem that it can be used only in a limited structure. Moreover, since it was necessary to form the shape of the opening 103 larger than the width dimension of the main material 101, the strength of the main material 101 was also lowered. In addition, it is necessary to form the gap 111 in the conventional opening 103 in order to allow the tip portions 109 and 109 to expand, and the shape of the opening 103 is complicated, and it takes time and effort to form it. Had problems. Furthermore, such a decrease in the strength of the main material 101 has a problem in that a decrease in the bonding strength between the main material 101 and the steadying material 102 is also caused.

本発明は、このような課題を解決すべく創案されたものであり、小断面形状の主材と振れ止め材とを容易に接合することができるとともに、主材と振れ止め材との接合強度が高い下地構造を提供することを課題とする。   The present invention has been devised to solve such problems, and can easily join a main material having a small cross-sectional shape and an anti-rest material, and a bonding strength between the main material and the anti-rest material. It is an object of the present invention to provide a high foundation structure.

このような課題を解決すべく創案された本発明は、開口部が形成された主材と、基板部と該基板部の両端に形成された一対のフランジ部とを備える振れ止め材と、からなる下地構造であって、前記開口部には、両側部から内方に向かって突出する一対の突出部が形成されており、前記基板部には、内方に向かって凹む凹条が形成されており、前記一対のフランジ部の先端には、それぞれ他方のフランジ部側に向けて延出されたリップ部が互いに隙間を有して形成されており、前記開口部に前記振れ止め材を貫通させて、前記突出部と前記凹条とが係合されるとともに前記リップ部が前記開口部に密接されることを特徴としている。   The present invention created in order to solve such a problem includes a main material having an opening, and a steadying material including a substrate portion and a pair of flange portions formed at both ends of the substrate portion. A pair of projecting portions projecting inward from both side portions are formed in the opening portion, and a groove that is recessed inward is formed in the substrate portion. And a lip portion extending toward the other flange portion is formed at the tip of the pair of flange portions with a gap between each other, and the steadying material passes through the opening. Thus, the protruding portion and the concave stripe are engaged with each other, and the lip portion is in close contact with the opening.

かかる発明によれば、開口部の一対の突出部と基板部に形成された凹条とが係合され、かつ、リップ部が開口部に密接しているため、主材に振れ止め材を嵌め合わせて容易に接合することができる。また、主材に振れ止め材を接合する際に、基板部が外側から内側にたわむとともに、フランジ部が上方にたわむため、主材の一部に振れ止め材の先端を逃がすための間隙を形成する必要がない。そのため、従来の下地構造における主材よりも強度の高い主材を形成することができる。   According to this invention, since the pair of projecting portions of the opening and the recess formed in the substrate portion are engaged, and the lip portion is in close contact with the opening, the anti-sway material is fitted to the main material. They can be easily joined together. Also, when the steady rest material is joined to the main material, the base plate part bends from the outside to the inside, and the flange part bends upward, so that a gap to escape the tip of the steady rest material is formed in a part of the main material. There is no need to do. Therefore, it is possible to form a main material having higher strength than the main material in the conventional base structure.

また、前記下地構造において、前記リップ部の隙間が、前記突出部と同じ幅寸法からなり、一方の突出部と前記凹条とが係合されるとともに前記リップ部の先端が他方の突出部に当接していれば、凹条による突出部の係合に加えて、リップ部により突出部を挟む形で噛み合い、より強固に接合することが可能となる。   Further, in the base structure, the gap of the lip portion has the same width as that of the protruding portion, and the one protruding portion and the recess are engaged, and the tip of the lip portion is connected to the other protruding portion. If they are in contact, in addition to the engagement of the protrusions by the concave stripes, it is possible to engage the lip portions so that the protrusions are sandwiched between them, and to join them more firmly.

また、前記下地構造において、前記一対のフランジ部のうち一方が、前記開口部の底辺部に当接されていれば、接合部において作用する応力を好適に分散して、接合強度をより高めることが可能となる。   Further, in the base structure, if one of the pair of flange portions is in contact with the bottom portion of the opening, the stress acting on the joint is preferably dispersed to further increase the joint strength. Is possible.

また、前記下地構造において、前記一対のフランジ部に、内方に向かって凹む凹条が形成されていれば、フランジ部の剛性が大きくなり、振れ止め材の強度を高めることができる。さらに、部材幅の大きい主材を利用して下地構造を形成する場合には、当該振れ止め部材を基板部が上側または下側になるように、主材の開口部に配置することも可能となり、開口部の形状に応じて振れ止め材を配置する向きを変更することが可能となる。また、フランジ部の剛性が高いことから、一般的な天井の野縁受けとして使用すれば、より板厚の薄い材料で同程度の強度を維持することが可能である。これにより、振れ止め材を規格化して大量生産することで、製造費を大幅に削減することが可能となる。   Moreover, in the said base structure, if the groove | channel which dents inward is formed in the said a pair of flange part, the rigidity of a flange part will become large and the intensity | strength of a steadying material can be raised. Furthermore, when the base structure is formed using the main material having a large member width, the steadying member can be disposed in the opening of the main material so that the substrate portion is on the upper side or the lower side. The direction in which the steady rest is arranged can be changed according to the shape of the opening. In addition, since the flange portion has a high rigidity, if it is used as a general edge guard for a ceiling, it is possible to maintain the same strength with a thinner material. This makes it possible to significantly reduce manufacturing costs by standardizing the steady rest material and mass-producing it.

本発明に係る下地構造によれば、小断面形状の主材と振れ止め材とを容易に接合することができるとともに、主材と振れ止め材との接合強度が高い下地構造を容易に構築することができるため、建築物の強度及び施工性を高めることができる。   According to the foundation structure according to the present invention, a main material having a small cross-sectional shape and an anti-rest material can be easily joined, and an underlying structure having a high joint strength between the main material and the anti-rest material is easily constructed. Therefore, the strength and workability of the building can be improved.

FIG. 2 is an enlarged view of a portion where the main material and the steady rest according to the present embodiment are orthogonal to each other. FIG. 3 is a front view of the main material according to the present embodiment. FIG. 4 is a cross-sectional view of the steady rest material according to the present embodiment. FIGS. 5A and 5B are front views showing the case where the steady rest material is joined to the main material in each stage in the base structure according to the present embodiment, where FIG. 5A is an insertion stage, and FIG. Stage (c) shows the joining stage.

下地構造１は、図１に示すように、等間隔に略垂直に配設された主材２，２・・・（以下、本実施形態においてはスタッド２とする）と、このスタッド２を貫通し、略直交して配設される振れ止め材３，３とからなる。本実施形態に係る下地構造１は、例えば、スタッド２の上端及び下端にランナーＲ，Ｒを配設し、スタッド２の側面に石膏ボード等Ｇを貼設することにより、壁組みＫとして使用される。
なお、下地構造１の使用用途は、壁組みＫに限定されるものではなく例えば、床組み、天井等建物の下地構造として広く用いることができる。壁組みＫの下地材として、石膏ボード等Ｇを使用するものとしたが、下地材を構成する材料は限定されないことはいうまでもなく、適宜公知の材料の中から選定して使用すればよい。 As shown in FIG. 1, the base structure 1 includes main members 2, 2... (Hereinafter referred to as a stud 2 in the present embodiment) disposed substantially perpendicularly at equal intervals, and through the stud 2. The anti-sway members 3 and 3 are arranged substantially orthogonal to each other. The foundation structure 1 according to the present embodiment is used as a wall set K by arranging runners R and R at the upper and lower ends of the stud 2 and affixing a gypsum board or the like G to the side surface of the stud 2, for example. The
The usage application of the foundation structure 1 is not limited to the wall assembly K, and can be widely used as an underlying structure of a building such as a floor assembly and a ceiling. As the base material for the wall assembly K, gypsum board or the like G is used, but it is needless to say that the material constituting the base material is not limited, and may be appropriately selected from known materials. .

本実施形態において、スタッド２は、図２および図３に示すように、鋼製の中空角材であって平面視略長方形に形成されている。対向する一対の面には、振れ止め材３が挿通される開口部４，４が穿設されている。一対の開口部４，４は、略同等の高さ位置に形成されており、図１に示すように、スタッド２の長手方向（上下方向）に２箇所形成されている。さらに、隣り合うスタッド２，２・・・に形成された開口部４，４・・・はそれぞれ同等の高さ位置に形成されている。一つのスタッド２に穿設される開口部４の個数は、下地構造１の用途、設計強度等に応じて適宜設定すればよい。なお、本実施形態に係るスタッド２の開口部４が形成された対向する一対の面には、それぞれ凸凹が形成されており、スタッド２の強度を向上させているが、この凸凹は必要に応じて形成すればよく、必ずしも形成する必要はない。   In this embodiment, as shown in FIGS. 2 and 3, the stud 2 is a steel hollow square member and is formed in a substantially rectangular shape in plan view. Openings 4 and 4 through which the steady rest 3 is inserted are formed in a pair of opposed surfaces. The pair of openings 4 and 4 are formed at substantially the same height, and are formed in two places in the longitudinal direction (vertical direction) of the stud 2 as shown in FIG. Further, the openings 4, 4... Formed in the adjacent studs 2, 2... Are formed at the same height position. What is necessary is just to set suitably the number of the opening parts 4 drilled in one stud 2 according to the use of the base structure 1, design strength, etc. FIG. In addition, although the unevenness | corrugation is each formed in a pair of surface where the opening part 4 of the stud 2 which concerns on this embodiment was formed, the intensity | strength of the stud 2 is improved, this unevenness is as needed. However, it is not always necessary to form them.

スタッド２に形成された開口部４は、図３に示すように、曲線を含む上辺部４ａと、両側を形成する側部４ｂ，４ｂと、略水平な直線である底辺部４ｃと、からなり、略左右対称に形成されている。
開口部４の幅Ｈ１は、振れ止め材３が挿通されるため、振れ止め材３の幅Ｈ２と同等以上の幅寸法となるように形成されている。なお、開口部４の形状は限定されないことはいうまでもない。例えば、本実施形態において、上辺部４ａは、屈折又は屈曲させると応力が集中し、欠損する可能性があることから、円弧となるように形成されているが、上辺部４ａの形状は円弧に限定されるものではない。 As shown in FIG. 3, the opening 4 formed in the stud 2 includes an upper side 4a including a curve, side portions 4b and 4b forming both sides, and a bottom side 4c that is a substantially horizontal straight line. , Is substantially symmetrical.
The width H <b> 1 of the opening 4 is formed to have a width dimension equal to or greater than the width H <b> 2 of the steady rest 3 because the steady rest 3 is inserted. Needless to say, the shape of the opening 4 is not limited. For example, in the present embodiment, the upper side 4a is formed to have an arc shape because stress concentrates and may be lost when it is refracted or bent, but the shape of the upper side 4a is an arc. It is not limited.

側部４ｂは、底辺部４ｃと略垂直な直線に形成されており、下部に内方に向かって突出する突出部４ｄが形成されている。左右の側部４ｂ，４ｂに形成された一対の突出部４ｄ，４ｄは、同じ高さ位置に形成されている。本実施形態では、突出部４ｄを、円弧状に形成するものとするが、突出部４ｄの形状は限定されるものではなく、例えば多角形状に形成してもよい。また、突出部４ｄの底辺部４ｃからの高さ（下部４ｆの高さ）は、後記する振れ止め材３の凹条３ｃに対応する位置となるように構成されている。また、突出部４ｄから上辺部４ａまでの高さ（上部４ｅの高さ）は、振れ止め材３の高さ（基板部３ａの長さ）よりも長く形成されている。なお、説明において、側部４ｂの突出部４ｄよりも上方の直線部分を上部４ｅ、突出部４ｄよりも下方の直線部分を下部４ｆと称する。   The side part 4b is formed in a straight line substantially perpendicular to the base part 4c, and a protruding part 4d protruding inward is formed in the lower part. The pair of protrusions 4d and 4d formed on the left and right side portions 4b and 4b are formed at the same height position. In the present embodiment, the protruding portion 4d is formed in an arc shape, but the shape of the protruding portion 4d is not limited, and may be formed in, for example, a polygonal shape. Moreover, the height from the bottom side part 4c of the protrusion part 4d (height of the lower part 4f) is comprised so that it may become a position corresponding to the groove 3c of the steadying material 3 mentioned later. Further, the height from the protruding portion 4d to the upper side portion 4a (the height of the upper portion 4e) is longer than the height of the steadying material 3 (the length of the substrate portion 3a). In the description, a straight line portion above the protruding portion 4d of the side portion 4b is referred to as an upper portion 4e, and a straight line portion below the protruding portion 4d is referred to as a lower portion 4f.

底辺部４ｃは、スタッド２の長手方向に対して直角であって、平坦に形成され、後記する振れ止め材３のフランジ部３ｂと当接される。なお、底辺部４ｃの形状は、前記のものに限定されるものではなく、例えば、左右の角部の形状を円弧となるように形成することで、応力が集中することを防止してもよい。この場合において、底辺部４ｃは、左右の角部が、後記するフランジ部３ｂの基端部３ｄおよび先端部３ｆの形状に沿った線形とすることで、底辺部４ｃとフランジ部３ｂとが密接し、より強固にスタッド２と振れ止め材３とが接合される構造とするのが望ましい。   The bottom 4c is perpendicular to the longitudinal direction of the stud 2 and is formed flat, and abuts against a flange 3b of the steady rest 3 described later. In addition, the shape of the bottom part 4c is not limited to the above-mentioned thing, For example, it may prevent that stress concentrates by forming the shape of the right and left corner part so that it may become a circular arc. . In this case, the bottom portion 4c is such that the left and right corners are linear along the shapes of the proximal end portion 3d and the distal end portion 3f of the flange portion 3b described later, so that the bottom portion 4c and the flange portion 3b are in close contact with each other. In addition, it is desirable to have a structure in which the stud 2 and the steady rest material 3 are joined more firmly.

なお、本実施形態においては、開口部４を前記したように形成したが、これに限定されるものではなく、他の形状であってもよい。例えば、振れ止め材３の開口部４への挿入をし易くするように、上辺部４ａの幅を広くし、側部４ｂを、上端（上辺部４ａとの接続点）から突出部４ｄに向かうにしたがって徐々に幅が狭まるテーパ状に形成してもよい。また、底辺部４ｃの後記する振れ止め材３の凹条３ｄに対応する箇所に突出部を形成してもよい。   In addition, in this embodiment, although the opening part 4 was formed as mentioned above, it is not limited to this, Other shapes may be sufficient. For example, the width of the upper side portion 4a is increased so that the steady rest member 3 can be easily inserted into the opening portion 4, and the side portion 4b is directed from the upper end (connection point with the upper side portion 4a) to the protruding portion 4d. It may be formed in a tapered shape whose width gradually decreases according to the above. Moreover, you may form a protrusion part in the location corresponding to the groove 3d of the steady rest material 3 mentioned later of the bottom part 4c.

スタッド２は、一枚の鋼板に、打ち抜き加工によって開口部４を穿設した後、プレス加工及び折り曲げ加工により形成されている。本実施形態においては、図２に示すように、鋼板の両端部分をかしめて両端をはぜ折り部４ｇでつなげている。スタッド２は、本実施形態においては、前記した方法で形成したが、他の公知の方法で製造してもよい。   The stud 2 is formed by pressing and bending after opening the opening 4 in a single steel plate by punching. In this embodiment, as shown in FIG. 2, the both ends of a steel plate are caulked, and both ends are connected by a folded portion 4g. The stud 2 is formed by the above-described method in the present embodiment, but may be manufactured by another known method.

振れ止め材３は、図４に示すように、基板部３ａと、基板部３ａの両端から延出されたフランジ部３ｂ，３ｂとを有する形鋼であって、フランジ部３ｂ，３ｂは、基板部３ａを挟んで互いに対向するように形成されている。   As shown in FIG. 4, the steady rest member 3 is a section steel having a substrate portion 3a and flange portions 3b, 3b extending from both ends of the substrate portion 3a. The flange portions 3b, 3b They are formed so as to face each other across the portion 3a.

基板部３ａは、断面視で略直線に形成されており、その中央部には、振れ止め材３の軸方向に沿って凹む凹条３ｃが形成されている。この凹条３ｃは、開口部４の突出部４ｄと係合する形状に形成されている。つまり、凹条３ｃの深さは、突出部４ｄの高さと一致している。   The substrate portion 3a is formed in a substantially straight line in a cross-sectional view, and a recess 3c that is recessed along the axial direction of the steady rest material 3 is formed in the central portion thereof. The recess 3 c is formed in a shape that engages with the protrusion 4 d of the opening 4. That is, the depth of the recess 3c matches the height of the protrusion 4d.

フランジ部３ｂは、先端が自由端となっており、基端部３ｄと、振れ止め材３の軸方向に沿って内方に向かって凹む凹条３ｅと、先端部３ｆと、内方に向けて延出されるリップ部３ｇとからなる。   The flange portion 3b has a free end at the distal end, a proximal end portion 3d, a recess 3e recessed inward along the axial direction of the steady rest member 3, a distal end portion 3f, and an inward direction. The lip portion 3g is extended.

各フランジ部３ｂ，３ｂに形成されたリップ部３ｇ，３ｇは、互いに隙間を有した状態で形成されている。本実施形態では、この一対のリップ部３ｇ，３ｇの隙間の幅Ｈ４を、開口部４の突出部４ｄの幅Ｈ３と略同一に形成する。なお、一対のリップ部３ｇ，３ｇの隙間の幅Ｈ４は適宜設定すればよく、必ずしも突出部４ｄの幅Ｈ３と同一に形成する必要はない。   The lip portions 3g, 3g formed on the flange portions 3b, 3b are formed in a state having a gap therebetween. In the present embodiment, the width H4 of the gap between the pair of lip portions 3g, 3g is formed substantially the same as the width H3 of the protruding portion 4d of the opening 4. Note that the width H4 of the gap between the pair of lip portions 3g, 3g may be set as appropriate, and is not necessarily formed to be the same as the width H3 of the protruding portion 4d.

なお、本実施形態においては、振れ止め材３を前記したような形状に形成したが、これに限定されるものではなく、弾性変形可能に形成された基板部３ａに内方に向かって凹む凹条３ｃを含むものであれば他の形状であってもよい。   In the present embodiment, the steady rest member 3 is formed in the shape as described above. However, the present invention is not limited to this, and a recess recessed inwardly in the substrate portion 3a formed to be elastically deformable. Other shapes may be used as long as they include the strip 3c.

振れ止め材３は、一枚の鋼板をプレス加工及び折り曲げ加工をすることにより形成され、基板部３ａの凹条３ｃ及びフランジ部３ｂの凹条３ｅにより、基板部３ａおよびフランジ部３ｂ，３ｂが平坦に形成されたチャンネル材よりも剛性の高い部材に形成されている。   The steady rest 3 is formed by pressing and bending a single steel plate, and the substrate 3a and the flanges 3b and 3b are formed by the recess 3c of the substrate 3a and the recess 3e of the flange 3b. It is formed into a member having higher rigidity than the channel material formed flat.

次に、スタッド２と振れ止め材３の接合について段階を追って説明する。
まず、図５（ａ）に示すように、開口部４の上部（突出部４ｄよりも上方）に、振れ止め材３を、一対のフランジ部３ｂ，３ｂが上下になるように挿通する。なお、本実施形態では、振れ止め材３の基板部３ａが左、リップ部３ｇ，３ｇが右となるように、振れ止め材を配置するが、振れ止め材３の向きは限定されないことはいうまでもない。 Next, the joining of the stud 2 and the steady rest material 3 will be described step by step.
First, as shown in FIG. 5A, the steady rest member 3 is inserted into the upper portion of the opening 4 (above the protruding portion 4d) so that the pair of flange portions 3b and 3b are up and down. In the present embodiment, the steady rest material is arranged so that the substrate portion 3a of the steady rest material 3 is on the left and the lip portions 3g and 3g are on the right. However, the orientation of the steady rest material 3 is not limited. Not too long.

次に、振れ止め材３を側部４ｂ（上部４ｅ）に沿って下降させる。振れ止め材３の下側のフランジ部３ｂが、突出部４ｄ，４ｄに当接した後、さらに、振れ止め材３を下方に押し込むと、図５（ｂ）に示すように、フランジ部３ｂが凹条３ｅにおいて撓むことで、フランジ部３ｂが一対の突出部４ｄ，４ｄの間の通過が可能となる。この時、基板部３ａも撓むことで、より振れ止め材３を固定しやすくなる。フランジ部３ｂが一対の突出部４ｄ，４ｄを通過する際の振れ止め材３の変形形状は前記の形状に限定されるものではない。   Next, the steady rest material 3 is lowered along the side part 4b (upper part 4e). After the lower flange portion 3b of the steady rest 3 is brought into contact with the protrusions 4d and 4d, when the steady rest 3 is further pushed downward, as shown in FIG. The flange 3b can pass between the pair of protrusions 4d and 4d by bending at the concave 3e. At this time, the steadying material 3 can be more easily fixed by bending the substrate portion 3a. The deformation shape of the steady rest member 3 when the flange portion 3b passes through the pair of projecting portions 4d and 4d is not limited to the above shape.

そして、さらに振れ止め部材３を下方に押し込み、下側のフランジ部ｂ（基端部３ｄおよび先端部３ｆ）を底辺部４ｃに当接させる。この時、凹条３ｃの深さは、突出部４ｄの高さと一致しているため、凹条３ｃと突出部４ｄとが係合される。また、凹条３ｃの対向する位置に形成されたリップ部３ｇ，３ｇ同士の隙間３ｈの幅Ｈ４（図４参照）も、突出部４ｄの幅Ｈ３と同等の幅寸法に形成されているため、振れ止め部材３のリップ部３ｇ，３ｇ側も突出部４ｄと係合される。さらに、凹条３ｃの深さは、突出部４ｄの高さと一致しているとともに、開口部４の幅Ｈ１（図３参照）とフランジ部３ｂとの幅Ｈ２（図４参照）は同一であるため、基板部３ａは、開口部４の一方の側部４ｂに当接し、リップ部３ｇ，３ｇが他方の側部４ｂに当接する。これにより、スタッド２と振れ止め材３が強固に接合される。   Then, the steadying member 3 is further pushed downward, and the lower flange portion b (the base end portion 3d and the tip end portion 3f) is brought into contact with the bottom side portion 4c. At this time, since the depth of the recess 3c matches the height of the protrusion 4d, the recess 3c and the protrusion 4d are engaged. Further, the width H4 (see FIG. 4) of the gap 3h between the lip portions 3g and 3g formed at the position where the concave strip 3c is opposed is also formed to have a width dimension equivalent to the width H3 of the protruding portion 4d. The lip portions 3g and 3g side of the steadying member 3 are also engaged with the protruding portion 4d. Further, the depth of the recess 3c matches the height of the protrusion 4d, and the width H1 of the opening 4 (see FIG. 3) and the width H2 of the flange 3b (see FIG. 4) are the same. Therefore, the substrate portion 3a contacts one side portion 4b of the opening 4, and the lip portions 3g and 3g contact the other side portion 4b. Thereby, the stud 2 and the steady rest material 3 are joined firmly.

なお、本実施形態においては、開口部４の下部４ｆと底辺部４ｃは、略直角に形成されたが、これに限定されるものではない。例えば、下部４ｆと底辺部４ｃの形状を、基板部３ａと基端部３ｄとの形状および先端部３ｆとリップ部３ｇとの形状と略同等となるように形成して、両者が連続して当接するようにしてもよい。これにより、振れ止め材３と開口部４との接触面積が増加し、より強固に接合することができる。
また、さらに、突出部４ｄと基板部３ａの凹条３ｃの形状を略同等となるように形成すれば、基板部３ａが全体にわたって開口部４の側部に密接し、さらに強固に接合することができる。 In the present embodiment, the lower portion 4f and the bottom portion 4c of the opening 4 are formed at substantially right angles, but the present invention is not limited to this. For example, the shape of the lower part 4f and the base part 4c is formed so as to be substantially the same as the shape of the substrate part 3a and the base end part 3d and the shape of the tip part 3f and the lip part 3g. You may make it contact | abut. Thereby, the contact area of the steady rest material 3 and the opening part 4 increases, and it can join more firmly.
Furthermore, if the protrusion 4d and the recess 3c of the substrate portion 3a are formed so as to have substantially the same shape, the substrate portion 3a is in close contact with the side portion of the opening portion 4 and bonded more firmly. Can do.

また、スタッド２及び振れ止め材３の素材は鋼に限定されるものではなく、弾性変形した後に元の形状に復帰可能な素材であれば、例えば、アルミニウム、アルミニウム合金等の他の素材により構成することが可能である。   Further, the material of the stud 2 and the steady rest material 3 is not limited to steel, and may be composed of other materials such as aluminum and aluminum alloy as long as the material can be restored to its original shape after being elastically deformed. Is possible.

また、図３及び図４に示すように、本実施形態においては、底辺部４ｃ（開口部４）の幅Ｈ１と、振れ止め材３のフランジ部ｂの幅Ｈ２は、略同等に形成されているがこれに限定されるものではない。例えば、底辺部４ｃの幅Ｈ１と、振れ止め材３のフランジ部３ｂの幅Ｈ２は、Ｈ１＜Ｈ２となるように、形成してもよい。これにより、スタッド２と振れ止め材３が接合した際に、振れ止め材３の内側から外側に向けて付勢力が働くため、より強固に接合することができる。   As shown in FIGS. 3 and 4, in the present embodiment, the width H1 of the base 4c (opening 4) and the width H2 of the flange b of the steady rest 3 are formed substantially equal. However, it is not limited to this. For example, the width H1 of the bottom portion 4c and the width H2 of the flange portion 3b of the steady rest 3 may be formed so that H1 <H2. Thereby, when the stud 2 and the steady rest material 3 are joined, an urging force acts from the inside to the outside of the steady rest material 3, so that the joining can be more firmly performed.

以上、本実施形態における下地構造１によれば、スタッド２の開口部４に振れ止め材３を挿入した後、振れ止め材３を下降させて、開口部４の一対の突出部４ｄ，４ｄと、基板部３ａの凹条３ｃおよびリップ部３ｇ同士の隙間３ｈとを係合させるのみで作業が完了するため、作業が容易である。   As described above, according to the base structure 1 in the present embodiment, after the steadying material 3 is inserted into the opening 4 of the stud 2, the steadying material 3 is lowered, and the pair of protrusions 4 d and 4 d of the opening 4 Since the operation is completed only by engaging the concave strip 3c of the substrate portion 3a and the gap 3h between the lip portions 3g, the operation is easy.

また、開口部４の突出部４ｄと、基板部３ａの凹条３ｃとを係合するとともに、開口部４の突出部４ｄをリップ部３ｇ同士の隙間３ｈに挿入して噛み合せるため、振れ止め材３の垂直方向及び横方向の移動を規制することができる。
また，スタッド２に振れ止め材３を接合する際に、フランジ部３ｂは凹条３ｅにおいてたわむことで伸縮するため、従来発明のようにスタッド２の一部にフランジ部３ｂの先端部３ｅを逃がすための間隙１１１（図８（ｃ）参照）等を形成する必要がない。そのため、従来のスタッド１０１よりも強度の高いスタッド２を形成することができる。 In addition, the protrusion 4d of the opening 4 and the recess 3c of the substrate 3a are engaged, and the protrusion 4d of the opening 4 is inserted into the gap 3h between the lip portions 3g to engage with each other. The movement of the material 3 in the vertical and lateral directions can be restricted.
Further, when the steady rest member 3 is joined to the stud 2, the flange portion 3 b expands and contracts by being bent in the recess 3 e, so that the tip portion 3 e of the flange portion 3 b escapes to a part of the stud 2 as in the conventional invention. Therefore, there is no need to form a gap 111 (see FIG. 8C) or the like. Therefore, the stud 2 having higher strength than the conventional stud 101 can be formed.

また、振れ止め材３のフランジ部３ｂに、内方に向けて凹む凹条３ｅが形成されているため、フランジ部３ｂの剛性が大きくなり、振れ止め材３の強度を高めることができる。   Moreover, since the concave part 3e recessed inward is formed in the flange part 3b of the steadying material 3, the rigidity of the flange part 3b becomes large, and the intensity | strength of the steadying material 3 can be raised.

また、本実施形態においては、突出部４ｄと凹条３ｃだけでなく、一方の側部４ｂと基板部３ａ、他方の側部４ｂとリップ部３ｇ，３ｇ、底辺部４ｃと一方のフランジ部３ｂの基端部３ｄおよび先端部３ｆがそれぞれ当接するため、スタッド２と振れ止め材３とが強固に接合されている。つまり、従来の発明は、図８に示すように、先端部１０９と基端部１１０の離間した二点で開口部１０３と当接されていたため、当接箇所に荷重が集中して作用していたが、本実施形態によれば、荷重が分散して作用することから、接合強度をより高めることができる。
また、開口部４の側部４ｂと基板部３ａまたはリップ部３ｇ，３ｇが連続して密接することにより、スタッド２と振れ止め材３が擦れ合うときに発生する金属音を抑制すると共に、ガタつきを防止することができる。 In the present embodiment, not only the protrusion 4d and the recess 3c, but also the one side 4b and the substrate 3a, the other side 4b and the lips 3g and 3g, the bottom 4c and the one flange 3b. Since the base end portion 3d and the tip end portion 3f are in contact with each other, the stud 2 and the steadying member 3 are firmly joined. That is, in the conventional invention, as shown in FIG. 8, the load 103 is concentrated on the contact portion because it is in contact with the opening 103 at two points apart from the distal end portion 109 and the proximal end portion 110. However, according to this embodiment, since the load acts in a distributed manner, the bonding strength can be further increased.
Further, the side portion 4b of the opening 4 and the substrate portion 3a or the lip portions 3g and 3g are continuously brought into close contact with each other, thereby suppressing the metal sound generated when the stud 2 and the steady rest 3 are rubbed together, and rattling. Can be prevented.

さらに、凹条３ｃおよび隙間３ｈが形成されていることにより、振れ止め材３の押し込み時における、振れ止め材３と側部４ｂ，４ｂとの接触面積が減少し、互いの摩擦を減少させることができるため、振れ止め材３をスムーズに押し込むことができると共に、摩擦による金属音を低減することができる。   Furthermore, by forming the recess 3c and the gap 3h, the contact area between the steady rest 3 and the side parts 4b and 4b when the steady rest 3 is pushed in decreases, and the mutual friction is reduced. Therefore, the steady rest material 3 can be pushed in smoothly, and metal noise due to friction can be reduced.

以上、本発明における最良の実施形態について説明したが、当該実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において適宜変更可能である。   The best embodiment of the present invention has been described above, but the present invention is not limited to this embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

例えば、前記実施形態では、振れ止め材３を、一対のフランジ部３ｂ，３ｂが上下に位置するように配置するものとしたが、図６に示す下地構造１’のように、スタッド２’の部材幅が大きく、開口部４’の幅を大きく形成することが可能な場合には、フランジ部３ｂ，３ｂが左右に位置するように、振れ止め材３を使用してもよい。この時、フランジ部３ｂには凹条３ｅが形成されているため、一対の凹条３ｅ，３ｅを開口部４’の突出部４ｄ，４ｄに係合させれば、スタッド２と振れ止め材３とを強固に接合することができる。この時、振れ止め材３のリップ部３ｇ，３ｇが開口部４’の底辺部４ｃに当接していれば、より強固に接合することが可能となる。
つまり、前記実施形態に係る振れ止め材３は、縦方向と横方向との２方向の向きで使用が可能である。故に、当該振れ止め材３を使用する下地構造が限定されることがないため、振れ止め材３を規格部材として生産することで製造費の削減を図ることも可能である。 For example, in the above-described embodiment, the steady rest member 3 is disposed so that the pair of flange portions 3b and 3b are positioned above and below. However, as in the base structure 1 ′ illustrated in FIG. In the case where the member width is large and the width of the opening 4 ′ can be formed large, the steady rest member 3 may be used so that the flange portions 3b and 3b are positioned on the left and right. At this time, since the recess 3e is formed in the flange portion 3b, if the pair of recesses 3e, 3e are engaged with the protrusions 4d, 4d of the opening 4 ′, the stud 2 and the steady rest 3 Can be firmly joined. At this time, if the lip portions 3g, 3g of the steady rest member 3 are in contact with the bottom side portion 4c of the opening 4 ′, it is possible to join more firmly.
In other words, the steady rest material 3 according to the embodiment can be used in two orientations, the longitudinal direction and the lateral direction. Therefore, since the base structure using the steady rest material 3 is not limited, it is possible to reduce the manufacturing cost by producing the steady rest material 3 as a standard member.

また、振れ止め材３を横向き（フランジ部３ｂ，３ｂが左右となる）に配置する場合において、図６では、振れ止め材３の開放側（リップ部３ｇ，３ｇ側）を下方に向けた状態で接合しているが、振れ止め材３の上下を逆にして、解放側が上方を向くようにして接合してもよい。即ち、振れ止め材３の基板部３ａと、開口部４の下辺部４ｃとが当接するように接合してもよい。   Further, in the case where the steady rest material 3 is disposed sideways (the flange portions 3b and 3b are left and right), in FIG. 6, the open side (the lip portions 3g and 3g side) of the steady rest material 3 is directed downward. However, the steady rest member 3 may be turned upside down so that the release side faces upward. That is, you may join so that the board | substrate part 3a of the steadying material 3 and the lower side part 4c of the opening part 4 may contact | abut.

また、前記実施形態では、振れ止め材３として、フランジ部３ｂに凹条３ｅが形成されている場合について説明したが、振れ止め材３のフランジ部３ｂには、必ずしも凹条３ｅが形成されている必要はなく、図７に示す振れ止め材３’のように、凹条３ｅを省略してもよい。この振れ止め材３’を使用した下地構造１”によれば、下側のフランジ部３ｂが、開口部４の底辺部４ｃと全体にわたって当接するため、より強固にスタッド２と振れ止め材３との接合を行うことが可能となる。   Moreover, although the said embodiment demonstrated the case where the groove 3e was formed in the flange part 3b as the steadying material 3, the concave part 3e was not necessarily formed in the flange part 3b of the steadying material 3. There is no need to be there, and the recess 3e may be omitted as in the steady rest material 3 'shown in FIG. According to the foundation structure 1 ″ using the steady rest material 3 ′, the lower flange portion 3b is in contact with the bottom portion 4c of the opening 4 over the entire area, so that the stud 2 and the steady rest material 3 It becomes possible to perform joining.

また、前記実施形態では、振れ止め材３のリップ部３ｇ同士の隙間３ｈの幅Ｈ４を、開口部４の突出部４ｄの幅Ｈ３と同等に形成するものとしたが、振れ止め材３の形状はこれに限定されるものではない。例えば、図７に示す振れ止め材３’ のように、隙間３ｈ’ の幅Ｈ４’を突出部４ｄの幅Ｈ３よりも大きく形成した場合であっても、基板部３ａおよびリップ部３ｇ，３ｇと側部４ｂ，４ｂとが密接しているため、スタッド２と振れ止め材３とは、強固に接合される。   In the embodiment, the width H4 of the gap 3h between the lip portions 3g of the steady rest 3 is formed to be equal to the width H3 of the protrusion 4d of the opening 4. However, the shape of the steady rest 3 Is not limited to this. For example, even when the width H4 ′ of the gap 3h ′ is formed larger than the width H3 of the protruding portion 4d as in the steady rest material 3 ′ shown in FIG. 7, the substrate portion 3a and the lip portions 3g, 3g Since the side portions 4b and 4b are in close contact with each other, the stud 2 and the steady rest material 3 are firmly joined.

また、本発明に係る下地構造は、壁組みへの使用に限定されるものではなく、天井下地として使用してもよい。この場合、下地構造の主材の上面及び下面に石膏ボード等を貼り付けることで天井下地として使用される。同様に、本発明に係る下地構造を、床として使用してもよい。   Moreover, the foundation structure according to the present invention is not limited to use on a wall structure, and may be used as a ceiling foundation. In this case, it is used as a ceiling foundation by attaching a gypsum board or the like to the upper and lower surfaces of the main material of the foundation structure. Similarly, the ground structure according to the present invention may be used as a floor.

また、前記実施形態では、開口部の突出部と振れ止め材の凹条とを係合させるとともに、開口部の底辺部に振れ止め材の一方のフランジ部を当接させるものとしたが、振れ止め材の接合方向を逆にすることで、開口部の突出部と振れ止め材の凹条とを係合させるとともに、開口部の上辺部に振れ止め材の一方のフランジ部を当接させる構成としても、同様の接合強度を発現することが可能である。   In the above embodiment, the protrusion of the opening and the recess of the steadying material are engaged, and one flange of the steadying material is brought into contact with the bottom of the opening. A structure in which the protruding portion of the opening and the recess of the steadying material are engaged by reversing the joining direction of the fastening material, and one flange of the steadying material is brought into contact with the upper side of the opening. However, it is possible to develop the same bonding strength.
