ところで、前記第１，第２，第３のアングル材３，５，７の端部における前記係合凹部１７Ａ，１７Ｂ及び係合凸部１９，２１はレーザ加工によって形成されるものである。なお、レーザ加工装置は公知の構成であるが、次のようにレーザ加工が行われるものである。すなわち、レーザ加工装置において水平な軸心回りに回転自在かつ回転位置を割出し位置決め自在な回転チャックにアングル材を水平に把持する。そして、アングル材を長手方向の水平な軸心回りに回転位置決めすると共に、Ｘ，Ｙ，Ｚ軸方向へ移動自在なレーザ加工ヘッドの移動位置決めを行い、レーザ加工を行うことにより、前記第１，第２，第３のアングル材３，５，７の端部に傾斜接合面３Ｓ，５Ｓ，７Ｓ及び係合凹部１７Ａ，１７Ｂ、係合凸部１９，２１の加工を行うことができるものである。   By the way, the engaging concave portions 17A and 17B and the engaging convex portions 19 and 21 at the end portions of the first, second and third angle members 3, 5 and 7 are formed by laser processing. The laser processing apparatus has a known configuration, but laser processing is performed as follows. That is, the angle material is horizontally held by a rotary chuck that is rotatable around a horizontal axis and that can be indexed and positioned in a laser processing apparatus. Then, the angle member is rotationally positioned around a horizontal axis in the longitudinal direction, and the laser processing head that is movable in the X, Y, and Z axis directions is moved and positioned, and laser processing is performed, whereby the first, Inclined joint surfaces 3S, 5S, 7S, engaging concave portions 17A, 17B, and engaging convex portions 19, 21 can be processed at the ends of the second and third angle members 3, 5, 7. .

前述のように、第１，第２，第３の各アングル材３，５，７の端部をレーザ加工を行うと、レーザ加工された各レーザ加工面は、第１，第２，第３の各アングル材３，５，７における第１辺３Ａ，５Ａ，７Ａ及び第２辺３Ｂ，５Ｂ，７Ｂの外表面に対して、すなわち各アングル材３，５，７の長手方向に対して直交する面に加工されるものである。したがって、第１，第２，第３の各アングル材３，５，７における端部を、図２に示すように組合せると、各アングル材３，５，７の端面（レーザ加工面）は互に面接触するものである。   As described above, when laser processing is performed on the end portions of the first, second, and third angle members 3, 5, and 7, the laser-processed laser processed surfaces are first, second, and third. Are perpendicular to the outer surfaces of the first sides 3A, 5A, 7A and the second sides 3B, 5B, 7B, that is, to the longitudinal directions of the angle members 3, 5, 7 The surface to be processed. Therefore, when the end portions of the first, second, and third angle members 3, 5, and 7 are combined as shown in FIG. 2, the end surfaces (laser processed surfaces) of the angle members 3, 5, and 7 are obtained. They are in surface contact with each other.

以上のごとき構成において、第１，第２，第３の各アングル材３，５，７の端部を組合せるときには、次のように行うものである。すなわち、第２アングル材５における係合凸部１９と第３アングル材７における係合凹部１７Ａとを係合する（図３参照）。上述のように係合凹部１７Ａと係合凸部１９とを係合すると、係合凹部１７Ａ、係合凸部１９は蟻溝形（鳩尾形状）に形成してあるので、第２，第３のアングル材５，７は、それぞれの長手方向に外れることなく保持されるものである。   In the configuration as described above, when the end portions of the first, second, and third angle members 3, 5, and 7 are combined, the following is performed. That is, the engagement convex part 19 in the 2nd angle member 5 and the engagement recessed part 17A in the 3rd angle member 7 are engaged (refer FIG. 3). As described above, when the engagement recess 17A and the engagement protrusion 19 are engaged, the engagement recess 17A and the engagement protrusion 19 are formed in a dovetail shape (the dovetail shape). The angle members 5 and 7 are held without being detached in the respective longitudinal directions.

すなわち、係合凹部１７Ａと係合凸部１９との係合とを、治具を用いることなく容易に行うことができる。そして、前記係合凹部１７Ａと係合凸部１９とを係合した後は、各アングル材５，７の長手方向に離れ難くなるものである。   That is, the engagement between the engagement concave portion 17A and the engagement convex portion 19 can be easily performed without using a jig. And after engaging 17 A of engagement recessed parts and the engagement convex part 19, it becomes difficult to leave | separate in the longitudinal direction of each angle material 5 and 7. As shown in FIG.

前述のごとく、第２，第３のアングル材５，７の端部を組合せた後に、図３に矢印Ａで示すように、第１アングル材３をＸ軸方向に移動して、第１アングル材３における第１辺３Ａの傾斜接合面３Ｓを第２アングル材５における第２辺５Ｂの傾斜接合面５Ｓに接合すると、前記第１アングル材３に備えた係合凹部１７Ａと第２アングル材５に備えた係合凸部１９が係合する。また、前述のように、第１アングル材３を矢印Ａ方向に移動すると、第１アングル材３に備えた係合凹部１７Ｂと第３アングル材７に備えた係合凸部２１とが係合することになる。   As described above, after the end portions of the second and third angle members 5 and 7 are combined, the first angle member 3 is moved in the X-axis direction as shown by an arrow A in FIG. When the inclined joint surface 3S of the first side 3A of the material 3 is joined to the inclined joint surface 5S of the second side 5B of the second angle material 5, the engagement recess 17A provided in the first angle material 3 and the second angle material 5 is engaged. Further, as described above, when the first angle member 3 is moved in the direction of arrow A, the engagement concave portion 17B provided in the first angle member 3 and the engagement convex portion 21 provided in the third angle member 7 are engaged. Will do.

前述のごとく、既に組合された状態にある第２，第３のアングル材５，７の端部に対して、第１アングル材１の端部を組合せると、前記矢印Ａの反対方向へ第１アングル材３を取り外さなければ第２，第３のアングル材５，７の取り外しは行うことができないものである。換言すれば、第１，第２，第３のアングル材３，５，７の端部を組合せた状態においては、第１アングル材３を保持して全体を持上げることができるものである。   As described above, when the end portions of the first angle members 1 are combined with the end portions of the second and third angle members 5 and 7 that are already combined, the second direction is opposite to the direction of the arrow A. If the 1-angle material 3 is not removed, the second and third angle materials 5 and 7 cannot be removed. In other words, in the state where the end portions of the first, second, and third angle members 3, 5, and 7 are combined, the first angle member 3 can be held and lifted up as a whole.

ところで、第１，第２，第３のアングル材３，５，７の端部を組合せた後、第１アングル材３を、前記矢印Ａの反対方向へ外れないようにするには、第１アングル材３と第２，第３のアングル材５，７との接合部の一部にスポット溶接を行うこと、又は止めねじ、フックなどの適宜の固定具によって第１アングル材３を第２，第３のアングル材５，７の少なくとも一方に固定すればよいものである。この場合、第２，第３のアングル材５，７から第１アングル材３が外れないように固定すればよいものであるから、簡単な構成でもって実施可能である。   By the way, in order to prevent the first angle member 3 from coming off in the direction opposite to the arrow A after combining the end portions of the first, second, and third angle members 3, 5, and 7, Spot welding is performed on a part of the joint between the angle member 3 and the second and third angle members 5 and 7, or the first angle member 3 is attached to the second angle member 2 by an appropriate fixing tool such as a set screw or a hook. What is necessary is just to fix to at least one of the 3rd angle materials 5 and 7. FIG. In this case, it is sufficient to fix the first angle member 3 so that it does not come off from the second and third angle members 5 and 7, and therefore it can be implemented with a simple configuration.

ところで、前記フレーム構造体１における補強用のアングル材９，１１，１５の両端部の構成は、図４に示すごとき構成である。すなわち、アングル材９の両端部には、第２アングル材５における第１，第２の辺５Ａ，５Ｂの内角部分に係合する内角係合部２５が備えられていると共に、前記内角係合部２５を形成するために一方の辺を削除した切欠部２７が形成してある。そして、前記内角係合部２５の先端部には、第２，第３のアングル材５に形成した係合穴５Ｈ（図１参照）に嵌入される係合突出部２９が備えられている。この係合突出部２９の突出量は第２のアングル材５の肉厚にほぼ等しい突出量である。なお、補強用のアングル材１１における係合突出部２９は、第３アングル材７に形成した係合穴７Ｈに嵌入されるものである。   By the way, the configuration of both end portions of the reinforcing angle members 9, 11, 15 in the frame structure 1 is as shown in FIG. That is, both end portions of the angle member 9 are provided with inner angle engagement portions 25 that engage with inner angle portions of the first and second sides 5A and 5B of the second angle member 5, and the inner angle engagement. In order to form the portion 25, a cutout portion 27 in which one side is deleted is formed. An engagement protrusion 29 is provided at the distal end of the inner angle engagement portion 25 and is fitted into an engagement hole 5H (see FIG. 1) formed in the second and third angle members 5. The protrusion amount of the engagement protrusion 29 is a protrusion amount substantially equal to the thickness of the second angle member 5. Note that the engagement protrusion 29 in the reinforcing angle member 11 is inserted into the engagement hole 7 </ b> H formed in the third angle member 7.

前記補助アングル材１３の一端部は、図５に示すように、前記アングル材９，１１の端部と同一構成であるから、同一機能を奏する構成要素には同一符号を付することとして重複した説明は省略する。第２アングル材５とアングル材１１との間の前記補助アングル材１３においてアングル材１１に当接する他端部は、アングル材１１に当接する当接面に形成してあり、この当接面には、アングル材１１に備えた係合穴（図示省略）に嵌入される係合突出部３１が形成してある。なお、上記係合突出部３１の突出量は、他方のアングル材１３における係合突出部３１と押し合うことのないように、アングル材１１の肉厚の約１／２の突出量に設けてある。   As shown in FIG. 5, one end of the auxiliary angle member 13 has the same configuration as the end portions of the angle members 9 and 11, so that components having the same function are denoted by the same reference numerals and are duplicated. Description is omitted. The other end of the auxiliary angle member 13 between the second angle member 5 and the angle member 11 that contacts the angle member 11 is formed as a contact surface that contacts the angle member 11. Is formed with an engagement protrusion 31 that is inserted into an engagement hole (not shown) provided in the angle member 11. The protrusion amount of the engagement protrusion 31 is set to a protrusion amount that is approximately ½ of the thickness of the angle member 11 so that the engagement protrusion 31 of the other angle member 13 is not pressed against. is there.

上記構成により、各アングル材９，１１，１３，１５は、図１に示すように、フレーム構造体１に組合せることができるものである。なお、補助用アングル材９，１１，１３，１５は省略することも可能である。   With the above configuration, each of the angle members 9, 11, 13, 15 can be combined with the frame structure 1 as shown in FIG. The auxiliary angle members 9, 11, 13, and 15 can be omitted.

以上のごとき説明より理解されるように、本実施形態によれば、例えば組立治具などを用いることなく各アングル材の端部を組合せることが容易なものである。また、３方向に交差した状態に複数のアングル材の端部を組合せた後は、端部に備えた係合凹部と係合凸部との係合により、各アングル材の取り外しが難しくなるものであり、各アングル材の相互の固定が容易なものである。   As can be understood from the above description, according to the present embodiment, it is easy to combine the end portions of each angle member without using an assembly jig or the like, for example. In addition, after combining the ends of a plurality of angle members in a state intersecting in three directions, it becomes difficult to remove each angle member due to the engagement between the engagement recesses and the engagement protrusions provided at the ends. Thus, the angle members can be easily fixed to each other.
