The groove 2d can be provided so that the grooves 1d and ld of the groove 1a are continuous.
また、補助片２における補完部２ｅの正面は、補助片２
の脚部２ｂ、２ｂをダクト１のフランジ１ａ、１ａに当
接させて固定した時、フランジｌａ、ｌａの正面に対し
段差を持うこないように、脚部２ｂ、２ｂに対しフラン
ジ１ａの厚さ程度高く形成することが望ましい。Further, the front side of the complementary part 2e in the auxiliary piece 2 is
When the legs 2b, 2b of the duct 1 are brought into contact with the flanges 1a, 1a of the duct 1 and fixed, the thickness of the flange 1a is adjusted so that there is no step in front of the flanges la, la. It is desirable to form it somewhat high.
次に、上述の各部構成を持つダクトの接続作業について
説明する。Next, a description will be given of the connection work of the ducts having the above-mentioned configurations.
