２に後付けで取り付けることができる。Embodiment 1 FIGS. 1 to 4 show an embodiment of the present invention. The embedding box 1 of this embodiment is made of metal such as a steel plate, and has a box shape with an open front surface, as shown in FIG. 1, and has an opening 5 serving as an inlet for inserting an electric wire into the bottom plate 1b. The opening is formed only at the lower portion, and the wiring device 4 is covered with the lid from the back so as to provide fire resistance. Bottom plate 1b between top plate 1a and side plate 1d and left uncut
The rear plate 1c is separated from the rear plate 1c, and the both side plates 1d are expanded outward toward the edge of the opening, so that the two plates 1d are freely flexible starting from the connection with the back plate 1c. A plurality of ear pieces 6 are formed outwardly from the opening edge of both side plates 1d, and a wall plate 2 made of, for example, a gypsum board is sandwiched between the ear pieces 6 in a portion recessed from the opening edge. When the embedding box 1 is inserted into an embedding hole 2a formed in the wall plate 2 against the flexibility of the side plate 1d, the opening edge of the wall plate 2 And the claw 7 so that the embedding box 1 itself can be temporarily fixed to the wall plate 2. In addition,
The ear piece 6 functions to prevent the embedding box 1 from coming off from the embedding hole 2a and to improve the mounting force. The opening 5 serving as the inlet is subjected to a roll treatment so that the coating of the coating 8 of the electric wire is not damaged. The back plate 1c cuts the lower part, and the cut piece forms a tap 9 for connecting a ground wire to make the embedding box 1 have insulation. The cut-over portion is also subjected to a roll treatment so as not to damage the coating of the electric wire. At the opening edge of the top plate 1a, the insertion piece 11 having an insertion portion 11a through which a clip 10 for fixing the mounting frame 3 to which the ready-made embedded wiring device 4 is attached to the wall plate 2 is formed. It is formed toward. The holding member 10 is formed to have a substantially J-shaped cross section. As shown in FIG.
A pair of substantially L-shaped fixing pieces 10a formed at the base end are locked in mounting holes 13 formed on both sides of the base plate, and the fixing pieces 10a are temporarily fixed to each other. 6 (see FIG. 6), the front end portion is elastically locked to the back surface of the wall plate 2, thereby fixing the mounting frame 3 to the wall plate 2. When the fixing frame 14 is screwed to attach the mounting frame 3 to the embedding hole 2a of the wall plate 2, the lug 6 of the embedding box 1 is sandwiched between the mounting frame 2 and the wall plate 2, Box 1 is completely fixed. Further, the opening 5 of the embedding box 1 functions as an insertion portion through which the clip 10 attached to the lower portion of the attachment frame 2 is inserted. When the embedding box 1 is configured as in the present embodiment, the embedding box 1 is mounted in the embedding hole 2a formed in the wall plate 2 from the front, and the clamp 10 attached to the mounting frame 3 is fixed. The embedding box 1 can be fixed to the embedding hole 2a of the wall plate 2 together with the frame 3, and the embedding box 1 can be retrofitted to the wall plate 2 without previously embedding the embedding box 1.
なお、上述の説明では規格化された既製の埋込形の配
線器具４を縦に３個連設して取付可能な取付枠３が１個
取り付けられる大きさのものであったが、例えば第４図
に示すように２個の取付枠３を横に２列に取付可能な大
きさに形成してもよい。In the above description, the size of the mounting frame 3 is one in which three standardized ready-made buried wiring devices 4 can be mounted vertically and three can be mounted in a row. As shown in FIG. 4, two mounting frames 3 may be formed in a size that can be mounted horizontally in two rows.
〔実施例２〕 本発明の他の実施例を第５図及び第６図に示す。本実
施例は、上記実施例の挿入片11の挿通部11aを、挟み金

具10の取付に必要な隙間を極力小さく形成したものであ
り、この点を除いて上記実施例と同様のものである。Embodiment 2 FIGS. 5 and 6 show another embodiment of the present invention. In the present embodiment, the insertion portion 11a of the insertion piece 11 of the above embodiment is provided with
And the screw hole 10 of the clamp 10 through the fixing hole 12 of the mounting frame 3.
An insertion hole 11c through which a fixing screw 14 screwed to b is inserted is formed, and a gap necessary for attaching the clamp 10 is formed as small as possible. Except for this point, it is the same as the above embodiment.
ところで、例えば２つの取付枠３を取付可能な埋込ボ
ックス１を用いた場合、夫々の取付枠３に個別に挟み金
具10を取り付ける必要があり、挟み金具10の取付に時間
がかかり、しかも挟み金具10の係止状態にばらつきを生
じて埋込穴2a及び埋込ボックス１の挿通部11aへの挿入
が面倒になるという問題がある。By the way, for example, when the embedding box 1 to which the two mounting frames 3 can be mounted is used, it is necessary to separately mount the clamps 10 on each of the mounting frames 3, and it takes time to mount the clamps 10, and moreover, There is a problem in that the locking state of the metal fitting 10 varies, and it becomes troublesome to insert the embedding hole 2a and the embedding box 1 into the insertion portion 11a.
そこで、このような場合には、第７図に示すように、
２個の挟み金具10を一体に形成すると、取付が容易とな
り、埋込穴2a等への挿入も容易に行える。Therefore, in such a case, as shown in FIG.
When the two clamps 10 are integrally formed, the mounting becomes easy, and the insertion into the embedding hole 2a or the like can be easily performed.

がある。As described above, the present invention is formed of a metal material in the shape of a box with an open front surface, and the two side plates are expanded outward as they approach the opening edge side, so that they can be freely flexible starting from the connection portion with the back plate. Ear pieces to be engaged with the opening edges of the embedding holes formed in the wall plate are formed outward from the opening edges of the both side plates, and the wall plate is sandwiched between the ear pieces. Claws are formed on both sides of the board, and the insert is attached to the mounting frame for the embedded wiring device. The opening is formed in the bottom plate to introduce the electric wire and the clip metal, so that the mounting box can be mounted forward from the mounting hole formed in the wall plate and attached later. There are advantages that can be done.
