Description

[Detailed description of the invention] [Industrial field of application and overview of the invention] The present invention is a mounting structure for a boxboard, particularly a structure for embedding and fixing a boxboard in a wall such as a plasterboard where nails cannot be driven or wood screws cannot be screwed into the wall. It is related to.

In addition, in the present invention, the flange projecting from the opening end of the box and the fixing metal fittings are in contact with the entire outer periphery of a wall hole formed in a wall board such as a plasterboard, so that the box This ensures that it is securely fixed to the board.

[Prior art and its problems] There is already a structure for attaching a box stock to a wall material as described above, as disclosed in Japanese Utility Model Application Publication No. 186267/1983.

This item, as shown in Figure 5, is a box
Long mounting bolts 2, 2 are swingably passed through the flange 11 extending from the opening end of the box, and a pair of strip-shaped mounting fittings 3 are attached to the tips of the mounting bolts 2, 2.
0.30 screwed together.

In this conventional device, a wall hole 41 smaller than the size of the flange 11 and larger than the box 10 is bored in the wall plate 4, and the mounting brackets 30, 30 are arranged in a state in which the distance between the tips of the mounting bolts 2, 2 is narrowed. and box 1
0 to the back side of the wall plate 4. Mounting bracket 3
0 and 30 are independent from each other, the spacing between these mounting fittings 30 and 30 can be set to a smaller spacing than the arrangement pitch of the mounting bolts 2 and 2, so that they can be inserted in the manner described above.

After this, when the distance between the mounting brackets 30, 30 is widened and the mounting bolts 2, 2 are tightened, the mounting bracket 3
0 and 30 are pressed against the back surface of the wall plate 4, and the outer periphery of the wall hole 41 is compressed by the mounting fittings 30 and 30 and the collar body 11, and the box stock A is attached to the wall plate 4.

However, in this conventional type, the mounting bracket 30
Although there is an advantage that the box stock A can be attached to the wall plate 4 with the flange body 11 connected, that is, without being separated, there is a problem that the attachment strength is insufficient.

This is because the flange body 11 is attached to the wall hole 4 on the surface side of the wall board 4.
1, but on the back side,
Since the mounting brackets 30, 30 only come into contact along both side edges of the wall hole 41, in the case of plasterboard, etc., which is inferior in strength compared to wooden wall boards, the load applied to the box stock A is concentrated and the wall This is because the periphery of the wall hole 41 of the plate 4 will be damaged.

[Technical Problem] The present invention solves the problem of ``a rectangular wall hole 41 formed in a wall plate 4''.
By squeezing the inner periphery of the box 10 with the flange 11 extending from the outer periphery of the open front surface of the rectangular parallelepiped box 10 and the rectangular frame-shaped mounting bracket 30 that comes into contact with the back surface of the wall plate 4, In the box holder mounting structure in which a box holder A in which a gas holder is housed in a box 10 is mounted on a wall,
The object is to provide sufficient mounting strength even when the strength of the wall plate 4 is insufficient, and to make it possible to set a large space within the box 10 when a certain wall hole 41 is opened. shall be.

[Means] The technical means of the present invention taken to solve the above problem is as follows: ``The mounting bracket 30 is formed into a rectangular frame shape that is one size larger than the wall hole 41;
A screw hole 31 is drilled in each corner of the inner circumference of the box 10, and a tongue piece 32 is provided that protrudes from the corner of the wall hole 41 in the installed state. The box 10 has a shape that almost matches that of the box 10, and through holes 12, 12 are formed at positions facing the tongue piece 32 of the collar body 11 extending from the open end of the box 10, and the through holes 12 are inserted through each of the through holes. The fixing screw 70 is screwed into each of the screw holes 31.

[Effect] The above technical means works as follows.

When the box stock is attached, the mounting bracket 30 is in contact with the outer periphery of the wall hole 41 on the back surface of the wall plate 4, and the flange body 11 is in contact with the outer periphery of the wall hole 41 on the outer surface of the wall plate 4. Each tongue piece 32 projects into the wall hole 41 at each corner of the rectangular wall hole 41 . The cross-sectional shape of the box 10 is the same as that of the tongue piece 32.
Since it almost matches the inner circumferential shape of Box 1
At the corner portion of the outer circumferential surface of 0, a concave portion that approximately corresponds to the tongue piece 32 is formed.

The collar body 11 of the box 10 has a through hole 1 at a position facing the tongue piece 32 in the attached state.
2 is provided, this through hole 12 and tongue piece 32
The space between the two corresponds to the concave portion on the outer periphery of the box 10. Therefore, the fixing screw 70 inserted through the through hole 12 passes through the recessed portion and is screwed into the screw hole 31 of the tongue piece 32, and the four fixing screws 70 are used to connect the mounting bracket 30 to the collar. body 11 is tightened,
This causes the peripheral edge of the wall hole 41 to be compressed.

Fixing screws 70, 70 are installed in the recessed part of the corner part.
The flange 11 and the mounting bracket 30 are screwed together by inserting the flange 11 through the flange 11, so that each of the outer surfaces of the box 10 other than this recessed portion is brought close to each side of the inner periphery of the wall hole 41. However, the collar body 11 and the mounting bracket 30 can be screwed together.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

Since the entire outer periphery of the wall hole 41 is compressed by the plate-shaped flange 11 extending over the entire outer periphery of the box 10 and the mounting bracket 30, it is not possible to compress the outer periphery of the wall hole 41 partially. The mounting strength is improved compared to other types.

Furthermore, even when the outer surfaces of the box 10 other than the recessed portions are brought close to each side of the inner periphery of the wall hole 41, the collar body 11 and the mounting bracket 30 can be screwed together. Since the concave portion corresponds to a location that cannot be effectively used when housing the gas tank in the box 10, the substantial size of the box 10 to be accommodated in the certain wall hole 41 can be set large. In other words, when the substantial size of the box 10 is kept constant, the size of the wall hole 41 can be set small.

Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 62-46071, there is no need to provide a notch for inserting the fixing screw in the wall hole 41, and the wall hole 41 is simply opened in a rectangular shape. It's easy.
