【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、角型鋼管柱等の中空断面材の内部に設けら
れるダイアフラムに係り、特に住宅ユニットの柱等に利
用できる。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a diaphragm provided inside a hollow cross-section material such as a rectangular steel pipe column, and can be particularly used for a column of a housing unit.
従来より、ユニット住宅を構成する住宅ユニット等で
は、柱と梁との接続部分の強度を高めるために柱の内部
にダイアフラムを設けることがある。第４図に示すよう
に、従来のダイアフラム40は、端縁部41が斜めの開先
（グルーブ）となるようにガス切断あるいは機械切削等
で加工された１枚のプレート42で構成されている。2. Description of the Related Art Conventionally, in a housing unit or the like that constitutes a unit house, a diaphragm may be provided inside the pillar in order to increase the strength of the connecting portion between the pillar and the beam. As shown in FIG. 4, the conventional diaphragm 40 is composed of a single plate 42 processed by gas cutting or mechanical cutting so that the edge 41 becomes an oblique groove. .
このダイアフラム40は角型鋼管の柱43の内部に溶接固
定される。The diaphragm 40 is welded and fixed inside the column 43 of the rectangular steel pipe.
ところで、ダイアフラム40の溶接強度はそのルート間
隔で設定され、通常ルート間隔を大きくすると溶接強度
も高くなる。By the way, the welding strength of the diaphragm 40 is set according to its root interval, and if the normal root interval is increased, the welding strength also increases.
しかしながら、ダイアフラム40には溶接時に溶融金属
が裏に抜け落ちるのを防止するため、その端面に柱43の
内面に略接触していわゆる裏当てとなる裏当て部44を設
けなければならない。このため、裏当て部44を有しかつ
ルート間隔が大きくなるように、例えば図中二点鎖線で
示す加工線45に沿って切削加工することは極めて困難で
あるという問題があった。However, the diaphragm 40 must be provided with a backing portion 44, which is a so-called backing, which substantially contacts the inner surface of the column 43 at its end surface in order to prevent molten metal from falling off to the back during welding. For this reason, there is a problem in that it is extremely difficult to perform cutting along the machining line 45 indicated by the chain double-dashed line in the figure so as to have the backing portion 44 and increase the root interval.
本考案の目的は、裏当てを有しかつルート間隔の大き
さを容易に設定できるダイアフラムを提供することにあ
る。An object of the present invention is to provide a diaphragm that has a backing and can easily set the size of the root interval.
本考案のダイアフラムは、中空断面材の内部に設けら

く形成されかつ端縁部が開先加工された溶接プレートと
で構成されることを特徴とする。The diaphragm of the present invention is a diaphragm that is provided inside a hollow cross-section material to increase its rigidity, and is fixed to one surface of the backing plate that substantially fits inside the hollow cross-section material. At the same time, the hollow cross-section member is formed to have a dimension in the cross-sectional direction that is slightly smaller than that of the backing plate, and the welding plate has an edge portion grooved.
このような本考案においては、中空断面材の内面に略
嵌合する裏当てプレートと、この裏当てプレートよりも
一回り小さい溶接プレートとでダイアフラムを構成した
ので、溶接プレートの端縁部、裏当てプレートおよび中
空断面材の内面に囲まれた部分が開先となり、端縁部お
よび内面間がルート間隔となる。In the present invention, since the diaphragm is composed of the backing plate that substantially fits the inner surface of the hollow cross-section member and the welding plate that is slightly smaller than the backing plate, the edge of the welding plate, the backing plate, A portion surrounded by the inner surface of the contact plate and the hollow cross-section member is a groove, and a root interval is provided between the edge portion and the inner surface.
このため、溶接プレートの裏当てプレートに対する大
きさを適宜変更すればルート間隔も変更され、また裏当
てプレートが溶接時の裏当てとして作用する。Therefore, if the size of the welding plate with respect to the backing plate is appropriately changed, the root interval is also changed, and the backing plate acts as a backing during welding.
すなわち、本考案は、ダイアフラムを裏当てプレート
と溶接プレートとの２枚のプレートで構成し、様々な大
きさの溶接プレートを用いることで、切削加工等を行わ

りも厚くされている。As shown in FIG. 3, the diaphragm 1 has a backing plate 3 formed in a size and shape that substantially fits the inner surface of the column 2, and a welding fixed to one surface of the backing plate 3. And the plate 4. Welding plate 4
Is a direction along one surface of the backing plate 3, that is, the pillar 2
Sectional dimension l 1, l 2 is smaller than the dimension L 1, L 2 of the backing plate 3, respectively, that are slightly smaller form. However, the thickness t 1 is made larger than the thickness T 1 of the backing plate 3.
柱２の側壁2Aには、各々貫通孔５が形成されている。
この貫通孔５は、ダイアフラム１が設けられる位置、つ
まり柱２の端部から所定長さ離れた位置に形成されてい
る。A through hole 5 is formed in each side wall 2A of the pillar 2.
The through hole 5 is formed at a position where the diaphragm 1 is provided, that is, at a position separated from the end of the column 2 by a predetermined length.
また、柱２の端部には、略Ｌ字形に折曲された４枚の
裏当て板10が柱２の内面の各角部に合わせて固定され、
この裏当て板10を介して端部プレート11が柱２に溶接固
定されている。Further, at the end of the pillar 2, four backing plates 10 bent into a substantially L shape are fixed in accordance with the respective corners of the inner surface of the pillar 2,
The end plate 11 is welded and fixed to the column 2 via the backing plate 10.

て適宜な大きさの溶接プレート４でダイアフラム１を形
成すれば極めて容易にルート間隔を設定できる。According to the present embodiment as described above, since the diaphragm 1 is composed of the backing plate 3 and the welding plate 4, the size of the route interval can be adjusted simply by appropriately selecting the size of the welding plate 3 without special processing. Can be set. That is, since the route interval can be changed by changing the size of the welding plate 4, the route interval can be set extremely easily by forming the diaphragm 1 with the welding plate 4 having an appropriate size according to the required welding strength and the like. .
また、裏当てプレート３と溶接プレート４とを別体と
したので、従来のようにルート間隔を広げるための切削

At the time of main welding, a jig such as a magnet that supports the diaphragm 1 can be removed, and it does not interfere with the welding torch or the like, so that the welding operation can be facilitated.
さらに、ダイアフラム１の仮付けも柱２の貫通孔５を
利用して柱２の表面側から行え、治具に干渉されないの
で作業性を向上できる。Further, the temporary attachment of the diaphragm 1 can be performed from the surface side of the column 2 by utilizing the through hole 5 of the column 2, and the workability can be improved because it is not interfered with by the jig.
また、裏当てプレート３を仮付けするための貫通孔５
は極めて小さいものでよいので、柱２の強度が低下する
ことがなく、かつ適宜表面を研削仕上げすれば殆ど目立
たなくなり外観を損なうこともない。Also, a through hole 5 for temporarily attaching the backing plate 3
Is very small, the strength of the column 2 does not decrease, and if the surface is appropriately ground and finished, it is hardly noticeable and does not impair the appearance.
