Description

【０００１】
【発明の属する技術分野】
本発明は、例えばサッシ用などの開口部を形成する胴縁の接合連結、架構構造体と胴縁の接合など、各種構造材の接合連結に用いられる構造材の連結構造に関する。
【０００２】
【従来の技術】
例えば、図１４に示すように、サッシ取付け用の開口部３を形成する胴縁などの水平構造材１の端部を垂直構造材２の側面部に連結して取り付けるような場合、サッシ用の開口部３内に無用な突起物を突出させないよう、従来、図１５及び図１６に示すような連結構造が用いられていた。
【０００３】
この連結構造では、水平構造材１としてリップ溝型鋼が用いられ、その端部の側面に、両リップ１ａ，１ａの外面側にわたすように連結用金物としての当てプレート５１が、溶接Ｗにより取り付けられている。当てプレート５１の中央部には、リップ１ａ，１ａ間の開口部に連通するボルト通孔５２が形成されている。この水平構造材１は、そのリップ１ａ，１ａ間の開口部をサッシ用の開口部３とは反対の側に向けるようにして、その端部を垂直構造材２の側面部に突き合わせるように水平に配設される。そして、他の連結用金物としてのアングル材５３を用い、その一辺５３ａが垂直構造材２の反開口部３側の側面に向けるように配置されて溶接Ｗにより垂直構造材２の側面部に接合されると共に、アングル材５３のもう一方の辺５３ｂが、水平構造材１の当てプレート５１に外方から重ね合わせ状態にされ、ボルト５４、ナット５５にて当てプレート５１と締結、結合されて、水平構造材１の端部が垂直構造材２の側面部に連結結合されたものである。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記のような連結構造では、構造材１，２同士を連結するのに特殊技能を要する溶接が多用されており、その溶接が建築現場での溶接作業によるものであるか、工場での溶接作業によるものであるかどうかを問わず、連結部の形成を非常に厄介なものにしていた。
本発明は、上記のような技術背景において、構造材の連結部から溶接箇所を可及的に削減することができ、しかも、構造材同士をしっかりと、容易にかつ能率良く連結することができる、構造材の連結構造を提供することを課題とする。
【０００５】
【課題を解決するための手段】
上記課題は、第１構造材が連結用金物にて他の構造材に連結された構造材の連結構造において、
前記第１構造材は、リップ溝型材からなり、
前記連結用金物は、第１構造材に取り付けられる第１連結用金物を少なくとも備えており、
該第１連結用金物は、前記リップ溝型材の両リップの外面側にわたすように配置されたベース板部と、該ベース板部の内面側に連接され、リップ溝型材の両リップの間を通じて型材内部に突出されると共に両リップの内面側に突出される掛止用の足とを備え、ベース板部と足とでリップ溝型材の両リップを内外方向から挟んで第１構造材に取り付けられており、
第１構造材は、該第１連結用金物を他の構造材に直接に取り付けることにより、又は、第１連結用金物を他の構造材に他の連結用金物を介して間接的に取り付けることにより、他の構造材に連結されていることを特徴とする構造材の連結構造によって解決される。
【０００６】
即ち、本構造は、第１連結用金物が、そのベース板部と足とで、リップ溝型材からなる第１構造材の両リップを内外方向から挟んで第１構造材に取り付けられた構造であり、第１連結用金物は、第１構造材に対し、溶接によることなく、しっかりと取り付けられる。しかも、この取付け構造において、第１構造材のリップとは反対側の壁面から無用の突起物が外方に突出するというようなこともない。
【０００７】
上記の連結構造において、第１連結用金物の足が、ベース板部と直交する軸線回りの第１の回転位置において、リップ溝型材の両リップ間の開口を通じて出入り可能であり、前記第１の回転位置とは回転位置を異にする第２の回転位置において、リップ溝型材の両リップ間の開口を通じて出入り不能に形成されているものとすることにより、第１構造材への第１連結用金物の取付けは、第１連結用金物を第１構造材に対して第１の回転位置に向け、その足をリップ溝型材の両リップ間の開口を通じて型材内部に挿入し、しかる後、第１連結用金物を第１の回転位置から第２の回転位置へと回転させることだけで、第１連結用金物のベース板部と足とが第１構造材の両リップを内外方向から挟んだ状態となり、第１構造材への第１連結用金物の取付けが容易にかつ能率良く達せられる。
【０００８】
また、上記の連結構造において、第１連結用金物の足が弾性体からなり、弾性復元力を蓄えるように変形することによってリップ溝型材の両リップ間の開口を通じて挿入可能であり、挿入後、前記弾性復元力にて両リップの内面側に突出されるようになされた構造とすることにより、第１構造材への第１連結用金物の取付けは、第１連結用金物の足を第１構造材の両リップ間の開口の内方に向けて弾性反発力に抗して強制挿入するだけで、第１連結用金物のベース板部と足とが第１構造材の両リップを内外方向から挟んだ状態となり、第１構造材への第１連結用金物の取付けが容易に達せられる。
【０００９】
更に、弾性を利用したこの連結構造において、型材内部からのリップ間開口部を通じた前記足の抜出を規制する変形規制手段が備えられているものとすることにより、弾性を利用した強制挿入式の取付け構造において、第１連結用金物と第１構造材とがしっかりと結合される。
【００１０】
【発明の実施の形態】
次に、本発明の実施形態を図面に基づいて説明する。
【００１１】
以下に説明する各実施形態及び各変形例は、図１４に示すように、上下の水平構造材１，１の両端部を左右の垂直構造材２，２の側面部に連結してサッシ取付け用の開口部３を形成する場合に適用したものである。
【００１２】
図１ないし図３には第１実施形態を示す。図１及び図２は、サッシ取付け用の開口部３の向かって左上部分における水平構造材１と垂直構造材２との連結構造を示している。水平構造材１は本発明の第１構造材であり、垂直構造材２は第１構造材に連結される本発明の他の構造材である。そして、４は第１連結用金物であり、５は第２連結用金物である。第１連結用金物４は水平構造材１に取り付けられるものであり、第２連結用金物５は、第１連結用金物４と垂直構造材２とを連結するものである。
【００１３】
水平構造材１は、リップ溝型鋼からなり、サッシ用開口部３を挟む上側に、リップ１ａ，１ａを上方に向け、その端部を、溝型鋼などからなる垂直構造材２の側面部に突き合わせ状態とするように、水平に配設される。
【００１４】
第１連結用金物４は、ベース板部７と一対の掛止用の足８，８とからなる。ベース板部７は、水平構造材１の両リップ１ａ，１ａの外面側にわたされるような平面サイズを有する方形板部からなり、その中央部には、ボルト９と螺合可能なネジ孔１０が形成されている。そして、足８，８は、このベース板部７の内面側において、ネジ孔１０を挟む両側に、互いに平行に延ばされてベース板部７に一体的に取り付けられている。各足８，８は横断面Ｌ字状をなし、一方の辺８ａ，８ａは基端側の辺としてベース板部７に垂直に取り付けられ、もう一方の辺８ｂ，８ｂは先端側の辺としてそれぞれ外向きにされて外方に突出して備えられている。
【００１５】
即ち、この第１連結用金物４は、図３（イ−１）（イ−２）に示すように、足８，８を水平構造材１のリップ１ａ，１ａ間の開口の延びる方向と直交させた状態で、即ち第１の回転位置において、足８，８をリップ１ａ，１ａ間の開口部を通じて水平構造材１の内部に挿入できるようになされている。そして、この挿入状態から、図３（ロ−１）（ロ−２）に示すように、ベース板部７と直交する軸線回りでこの金物４を９０°回転変位させることにより、即ち第２の回転位置にすることにより、足８，８の先端側の辺８ｂ，８ｂがリップ１ａ，１ａの内面側に突出されるようになされており、これにより、水平構造材１の両リップ１ａ，１ａが、第１連結用金物４のベース板部７と足８，８の先端側の辺８ｂ，８ｂとに挟まれて、第１連結用金物４が、水平構造材１に対し、抜止め状態にしっかりと取り付けられるようになされている。
【００１６】
また、両足８，８の先端側の辺８ｂ，８ｂをリップ１ａ，１ａの内面側の可及的奥方に大きく突出させながらも、第１連結用金物４の上記回転を妨げないようにするため、各足８，８の先端側の辺８ｂ，８ｂの先端側の隅部は、傾斜面１１，１１にカットされている。
【００１７】
第２連結用金物５は、アングル材からなり、その一方の辺５ａには、ボルト通し孔１２が形成されている。
【００１８】
水平構造材１と垂直構造材２との連結は、まず、第１連結用金物４を水平構造材１に取り付ける。この取付けは、上記のように、第１連結用金物４の足８，８を、水平構造材１のリップ１ａ，１ａ間の開口の延びる方向と直交させた状態で、垂直構造材２のリップ１ａ，１ａ間の開口部を通じて水平構造材１の内部に挿入し、しかる後、この第１連結用金物４を９０°回転変位させるだけでよい。これにより両足８，８の先端側の辺８ｂ，８ｂがリップ１ａ，１ａの内面側に突出され、水平構造材１の両リップ１ａ，１ａが、第１連結用金物４のベース板部７と足８，８の先端側の辺８ｂ，８ｂとに挟まれて、第１連結用金物４は、水平構造材１にしっかりと取り付けられる。
【００１９】
次いで、第２連結用金物５の一方の辺５ｂを垂直構造材２の側面部に溶接Ｗにて接合すると共に、第２連結用金物５のもう一方の辺５ａと第１連結用金物４のベース板部７とを重ね合わせ、ボルト９をベース板部７のネジ孔１０に螺合させ、第１、第２の連結用金物４，５を締結一体化する。
【００２０】
以上により、水平構造材１と垂直構造材２とはしっかりと連結され、また、この連結状態において、サッシ用開口部３内に無用の突起物が突出してしまうこともない。また、溶接は、第２連結用金物５と垂直構造材２の接合にのみ用いられ、第２連結用金物５と第１連結用金物４、及び、第１連結用金物４と水平構造材１との接合部からは溶接が排除されて、溶接箇所が従来に比べて削減され、水平構造材１と垂直構造材２との連結を容易にかつ能率良く遂行していくことができる。また、ベース板部７にネジ孔１０を形成し、このネジ孔１０にボルト９を螺合させることによって第１、第２の連結用金物４，５を締結する構造としているから、ナット装着の手間を省け、水平構造材１と垂直構造材２との連結をより一層容易にかつ能率良く行っていくことができる。
【００２１】
図４に示す第１実施形態の変形例の１では、第１連結用金物４の両足８，８の先端側の辺８ｂ，８ｂが、外方に向け、ベース板部７から離れていく方向に傾斜していくよう勾配をつけられている。このような傾斜構造を採用することにより、第１連結用金物４の両足８，８の先端側の辺８ｂ，８ｂとベース板部７とが、足８，８のバネ弾性力によって水平構造材１のリップ１ａ，１ａをガタなくしっかりと強固に挟み込むことができると共に、同足８，８の先端側の辺８ｂ，８ｂをスムーズに水平構造材１のリップ１ａ，１ａの内面側に回転移行させることができる。
【００２２】
図５及び図６に示す第１実施形態の変形例の２は、水平構造材１と垂直構造材２とを、一つの第１連結用金物４だけで連結するように構成したものである。即ち、この第１連結用金物４は、アングル材からなり、一方の辺７をベース板部とし、このベース板部７に掛止用の足８，８が備えられている。また、もう一方の辺４ａの板部にはボルト通し孔１３が形成されている。
【００２３】
水平構造材１と垂直構造材２との連結は、上記実施形態と同様に、第１連結用金物４の足８，８を水平構造材１のリップ１ａ，１ａ間の開口部内方に挿入し、そして回転することにより、第１連結用金物４を水平構造材１に取り付ける。しかる後、同第１連結用金物４のもう一方の辺４ａを、垂直構造材２の側面部に沿わせ、ボルト１４，１４にて第１連結用金物４を垂直構造材２に締結するというようにして遂行される。本変形例によれば、溶接を完全に排除して、水平構造材１と垂直構造材２とをより一層容易にかつ能率良く連結することができると共に、水平構造材１と垂直構造材２とを連結する連結用金物を一種類となしえて連結部構造を簡素化することができる。
【００２４】
図７ないし図９に示す第２実施形態では、第１連結用金物４のベース板部７の内面側に備えられる足８が、第１実施形態のものとは異なる。即ち、本実施形態における足８は、板バネ弾性体によるもので、撓み性を有する板を筒状に巻き、その両側縁部をベース板部７の内面側のネジ孔１０を挟む両側位置に一体的に連接して取り付けられている。そして、この足８は、ベース板部７と隣り合う部分において、水平構造材１のリップ１ａ，１ａの間の開口幅程度にくびらされており８ｃ、それよりも先端側が両外方に向けて同開口幅を越えて膨出８ｄされ、更に先端側が先細り状８ｅに成形されている。
【００２５】
水平構造材１への第１連結用金物４の取付けは、図９（イ）（ロ）（ハ）に示すように、第１連結用金物４の足８をその先端側から、水平構造材１のリップ１ａ，１ａ間の開口を通じて水平構造材１の内部に強制挿入するだけでよい。この挿入過程で、足８は、先細り状の先端部８ｅによって水平構造材１のリップ１ａ，１ａ間の開口内方へと案内されていき、図９（ロ）に示すように、中間膨出部８ｄが両リップ１ａ，１ａに挟まれて、内方に弾性変形をしていき、足８が弾性復元力を蓄えていく。そして更に深く挿入していくことにより、中間膨出部８ｄが両リップ１ａ，１ａを越え、図９（ハ）に示すように、足８の基端くびれ部８ｃが両リップ１ａ，１ａ間に存置されると共に、中間膨出部８ｄが弾性復元力によって外方に膨出復帰する。これにより、両リップ１ａ，１ａは、弾性復帰した中間膨出部８ｄとベース板部７とに挟まれ、第１連結用金物４は、水平構造材１にしっかりと取り付けられる。その他は第１実施形態と同様である。
【００２６】
本実施形態では、第１連結用金物４の足８を、水平構造材１のリップ１ａ，１ａ間の開口内方に弾性力に抗して強制挿入していくだけでよく、水平構造材１への第１連結用金物４の取付けを非常に容易に遂行することができる。
【００２７】
図１０及び図１１に示す第２実施形態の変形例の１では、第２実施形態における第１連結用金物４の筒状の板バネ弾性体による足８の先端板部に、ベース板部７のネジ孔１０と同芯にネジ孔１６が形成されている。そして、第２連結用金物５をボルト９にて第１連結用金物のベース板部７に締結していく際に、このボルト９の先端部が、足８の先端板部のネジ孔１６とも螺合されるようになされており、このボルト９と、足８の先端板部のネジ孔１６とで、足８の変形規制手段が構成されている。これにより、第１連結用金物４に抜出方向のかなり強い力が作用した場合でも、足８がボルト９に保持されていることで、その中間膨出部８ｄが不本意に内方に変形したりせず、第１連結用金物４と水平構造材１とがしっかりとその結合状態を維持することができる。また、第１連結用金物４の足８にネジ孔１６を設けるだけの構造であるから、部品増もなく、簡素な構造にて強固な結合状態を形成することができる。
【００２８】
図１２及び図１３に示す第２実施形態の変形例の２では、図５及び図６に示す第１実施形態の変形例の２において、アングル形状の第１連結用金物４の一方の辺のベース板部７に、第２実施形態と同様の筒状の板バネ弾性体による足８を備えさせたものである。その他は、第１実施形態の変形例の２と同様である。
【００２９】
以上に本発明の実施形態を示したが、本発明は、これら形態に限られるものではなく、発明思想を逸脱しない範囲で、各種の変更をなし得るものであることはいうまでもない。例えば、上記実施形態では、サッシ取付け用の開口部３を囲む構造材同士を連結する場合の構造として構成されているが、その他、各種構造材同士の連結構造として広く用いられてよい。また上記実施形態では、リップ溝型材からなる構造材１の端部を他の構造材に連結する場合の構造を示しているが、リップ溝型材からなる構造材の長手方向中央部ないし中間部を他の構造材に連結する場合の構造として構成されてもよい。また、ベース板部７に備えられる足としては、その他、リップ溝型材の端部開口部からのみスライド嵌合が許容される形式の構造となされていてもよいし、その他、各種構成態様のものが採用されてよい。また、連結構造を構成する各構成部材は、鉄系金属材によるもののほか、アルミニウムなどの他の金属材などによるものであってもよい。
【００３０】
【発明の効果】
以上の次第で、本発明の構造材の連結構造は、第１連結用金物が、そのベース板部と足とで、リップ溝型材からなる第１構造材の両リップを内外方向から挟んで第１構造材に取り付けられた構造となされたものであるから、第１連結用金物を、第１構造材に対し、溶接によることなく、しっかりと取り付けることができる。しかも、この取付け構造において、第１構造材のリップとは反対側の壁面から無用の突起物が外方に突出するというようなこともなく、従って、例えば、サッシ取付け用の開口部を囲む構造材同士の連結構造などとして、有効的に用いることができる。
【００３１】
また、上記の連結構造において、第１連結用金物の足が、ベース板部と直交する軸線回りの第１の回転位置において、リップ溝型材の両リップ間の開口を通じて出入り可能であり、前記第１の回転位置とは回転位置を異にする第２の回転位置において、リップ溝型材の両リップ間の開口を通じて出入り不能に形成されているものとすることにより、第１構造材への第１連結用金物の取付けは、第１連結用金物の足を第１構造材の両リップ間開口部を通じて内部に挿入した後、該第１連結用金物を回転操作するだけで達せられ、第１構造材への第１連結用金物の取付けを容易にかつ能率良く行うことができる。また、第１構造材の長手方向のいずれの位置からでも第１連結用金物の取付けを行えて至便であることはいうまでもない。
【００３２】
また、上記の連結構造において、第１連結用金物の足が弾性体からなり、弾性復元力を蓄えるように変形することによってリップ溝型材の両リップ間の開口を通じて挿入可能であり、挿入後、前記弾性復元力にて両リップの内面側に突出されるようになされた構造とすることにより、第１構造材への第１連結用金物の取付けは、第１連結用金物の足を第１構造材の両リップ間の開口の内方に向けて弾性反発力に抗して強制挿入するだけで達せられ、第１構造材への第１連結用金物の取付けを、この場合もまた、容易にかつ能率良く行うことができる。また同様に、第１構造材の長手方向のいずれの位置からでも第１連結用金物の取付けを行えて至便であることはいうまでもない。
【００３３】
更に、弾性を利用したこの連結構造において、型材内部からのリップ間開口部を通じた前記足の抜出を規制する変形規制手段が備えられているものとすることにより、弾性を利用した強制挿入式の取付け構造において、第１連結用金物と第１構造材とをしっかりと強固に連結することができる。

An object is to provide a connecting structure of structural materials.
[0005]
[Means for Solving the Problems]
In the connection structure of the structure material in which the first structure material is connected to another structure material with a connection hardware,
The first structural material comprises a lip groove mold material,
The connection hardware includes at least a first connection hardware attached to the first structural material,
The first connecting hardware is connected to a base plate portion disposed on the outer surface side of both lips of the lip groove mold material and an inner surface side of the base plate portion, and passes between both lips of the lip groove mold material. It has a latching foot that protrudes inside the mold material and protrudes to the inner surface side of both lips, and is attached to the first structural material with both base lip and the lip groove material sandwiched from the inside and outside direction And
The first structural member is attached directly to the other structural member by attaching the first connecting hardware or indirectly attached to the other structural member via the other connecting hardware. This is solved by the connecting structure of the structural material, which is characterized by being connected to another structural material.
[0006]
That is, this structure is a structure in which the first connecting hardware is attached to the first structural member with the base plate portion and the foot sandwiching both lips of the first structural member made of the lip groove mold material from inside and outside. Yes, the first connecting hardware is firmly attached to the first structural material without welding. Moreover, in this mounting structure, useless protrusions do not protrude outward from the wall surface on the side opposite to the lip of the first structural member.
[0007]
In the above connection structure, the foot of the first connection hardware can be moved in and out through the opening between the lips of the lip groove mold material at the first rotation position around the axis orthogonal to the base plate portion, For the first connection to the first structural material, it is formed so that it cannot enter and exit through the opening between the lips of the lip groove mold material at the second rotational position different from the rotational position. The mounting of the hardware is directed to the first rotational position with respect to the first structural member with respect to the first structural member, and the foot is inserted into the mold member through the opening between the two lips of the lip groove mold member. A state in which the base plate portion of the first connecting hardware and the foot sandwich both lips of the first structural material from the inside and outside by simply rotating the connecting hardware from the first rotation position to the second rotation position. Of the first connecting hardware to the first structural material Give is achieved easily and well efficiency.
[0008]
Further, in the above connection structure, the foot of the first connecting hardware is made of an elastic body, and can be inserted through the opening between both lips of the lip groove mold material by deforming so as to store elastic restoring force. By adopting a structure that protrudes toward the inner surface side of both lips by the elastic restoring force, the first connecting hardware is attached to the first structural member by attaching the first connecting hardware to the first foot. The base plate part and the foot of the first connecting hardware push both lips of the first structural material inward and outward simply by forcibly inserting them against the elastic repulsion force toward the inside of the opening between the lips of the structural material. Thus, the first connecting hardware can be easily attached to the first structural member.
[0009]
Further, in this connection structure using elasticity, a force insertion type using elasticity is provided by providing deformation regulation means for regulating the extraction of the foot through the opening between the lips from the inside of the mold material. In the mounting structure, the first connecting hardware and the first structural member are firmly coupled.
[0010]
