An attachment member 16 for attaching the fire alarm F to the ceiling W can be screwed onto the nut 15 (see FIG. 5). In this embodiment, the bulging portion 14 and the nut 15 are screw portions to which the mounting member 16 is screwed. Moreover, the fixture main body 11 has connected a pair of screw part so that a pair of screw part (nut 15) may be opposingly arranged on the same straight line (virtual line L2). That is, the fixture main body 11 is curved so as to form a housing space T for the fire alarm F between a pair of screw portions (nuts 15).

  As shown in FIG. 1 (a), in the fixture body 11, each bulge portion 14 (in the direction in which the arc of the fixture body 11 extends is located outside the bulge portions 14 (nuts 15). A ruled hole 17 is formed at a position outside the both ends of the nut 15). The ruled hole 17 is formed at four places on the fixture main body 11, and is formed at two places outward from each bulging portion 14 (nut 15). Further, on the support surface 12 of the fixture main body 11, a sticking portion 18 is provided on the outer side of each positioning piece 13.

It can be separated so as to be located on the lower side. At this time, the first end portion 11a and the second end portion 11b are separated from each other until the panel material Wa can be sandwiched from both sides. And while inserting the peripheral part of the through-hole Wb between the 1st end part 11a and the 2nd end part 11b, it sends in the 1st end part 11a side to the back side of the panel material Wa. Then, in the fixture body 11, the panel material Wa is sandwiched between the first end portion 11a side and the second end portion 11b side.

  Then, as shown in FIG. 3, the first end portion 11a side is turned to the panel material so as to rotate the fixture body 11 with the panel material Wa sandwiched between the first end portion 11a and the second end portion 11b. If it sends in to the back side of Wa, the 1st edge part 11a side will enter into the back side of the panel material Wa so that the periphery of the through-hole Wb may be followed. At this time, the positioning piece 13 enters the inside of the through hole Wb. When the entire fixture body 11 is sent to the back side of the panel material Wa, the fixture body 11 returns to its original shape by itself, and the fixture body 11 can be disposed in the space S on the back side of the panel material Wa. . As shown in FIG. 4, when the pair of positioning pieces 13 enter the inside of the through hole Wb, the outer surface of the positioning piece 13 comes into contact with the peripheral surface of the through hole Wb, and the fixture 10 is positioned on the back side of the panel material Wa. Is done. In this positioning state, almost the entire support surface 12 is supported on the back surface of the panel material Wa at the periphery of the through hole Wb. Further, in the through hole Wb, the pair of bulging portions 14 (nuts 15) are arranged opposite to each other on the same straight line, and the fire alarm F is disposed between the pair of bulging portions 14 (nuts 15). An accommodation space T that can accommodate the upper portion is formed.

  And in the instrument fixture 10 arrange | positioned in the space S of the panel material Wa back side, the instrument fixture 10 is lifted, the release paper 18a is peeled, and the other surface of the sticking part 18 is stuck on the back surface of the panel material Wa. Then, the fixture fixture 10 is attached to the back side of the panel material Wa so that it cannot move. In this attached state, the nut 15 is in a state of facing the indoor side from the inside of the through hole Wb. After that, as shown in FIG. 5, when the two attachment members 16 inserted through the flange F2 of the fire alarm F are screwed into the nut 15, the flange F2 and the attachment body 11 form the through hole Wb in the panel material Wa. The fire alarm F is attached to the ceiling W. In this attached state, the upper part of the fire alarm F is accommodated between the pair of bulging portions 14 (nuts 15).

  In the case where the punching machine described above is not provided, the through hole Wc is formed by drawing the ruled line K on the panel material Wa as shown by a two-dot chain line in FIG. The instrument fixture 10 of the present embodiment can assist the operation of displaying the ruled lines K for forming the through holes Wc on the panel material Wa by using the ruled holes 17.

  That is, as shown in FIG. 6, on the surface (inner side surface) of the panel material Wa, the other surface (the support surface 12 and the back surface) of the instrument fixture 10 is set at a predetermined position of the instrument fixture 10. Contact surface). Next, a marker (not shown) is inserted into each of the four ruled holes 17 to display the ruled dot R on the surface of the panel material Wa. Then, by connecting the four ruled line points R with straight lines, a rectangular ruled line K can be drawn as shown by a two-dot chain line in FIG. Here, the four ruled holes 17 are formed in the fixture main body 11, and the nut 15 is provided at a position bulging from the inner peripheral edge of the fixture main body 11 from the center. It is located outside 15. Therefore, the ruled line K can be displayed on the panel material Wa so as to surround the two nuts 15.

  Thereafter, by cutting out the panel material Wa along the ruled line K, as shown in FIG. 7, a square-shaped through hole Wc can be formed in the panel material Wa. Then, when the fixture fixture 10 is disposed from the through hole Wc to the back side of the panel material Wa, the support surface 12 is abutted and supported outside the periphery of the through hole Wc on the back surface of the panel material Wa. While being supported by the panel material Wa, the nut 15 is disposed so as to face the room from the inside of the through hole Wc.

According to the above embodiment, the following effects can be obtained.
(1) The fixture body 11 is formed in a C shape from a synthetic resin material so that the panel material Wa can be sandwiched between the first end portion 11a and the second end portion 11b of the fixture body 11 from both sides. It can be flexibly deformed and can return to its original shape by itself. Then, the fixture body 10 is fed to the back side of the panel material Wa while the first end portion 11a and the second end portion 11b are bent and deformed so as to be separated from each other in the vertical direction. While passing along the back surface of the panel member Wa, the through hole Wb can be passed through and disposed in the space S on the back side of the panel material Wa. Therefore, by making the fixture main body 11 bendable and deformable, even if the space S on the back side of the panel material Wa is narrow, if there is a space S corresponding to the thickness of the fixture fixture 10, the fixture fixture 10 is placed on the back side of the panel material Wa. Can be arranged. As a result, the fixture 10 can be disposed also on the ceiling W where a large space S is not secured on the back side of the panel material Wa.
(2) The fixture body 11 can be bent and deformed, and can return to its original shape by itself. Therefore, when the first end portion 11a and the second end portion 11b are separated from each other in the vertical direction and the panel material Wa is inserted between the first end portion 11a and the second end portion 11b, the first end portion 11a becomes the original end portion 11a. It arrange | positions so that the back surface of the panel material Wa may be followed by the return to a shape. For this reason, when the fixture body 11 is fed to the back side of the panel material Wa, the fixture body 11 can be surely placed along the back surface of the panel material Wa, and even if the space S is small, the installation work of the fixture body 11 is possible. Can be made possible.

  (3) The fixture body 11 can be bent and deformed and can return to its original shape. Therefore, when the first end portion 11a and the second end portion 11b are separated from each other in the vertical direction and the panel material Wa is inserted between the first end portion 11a and the second end portion 11b, the original of the first end portion 11a is obtained. By returning to the shape, the panel material Wa can be clamped, the instrument fixture 10 can be prevented from dropping from the panel material Wa, and the instrument mounting tool 10 can be easily disposed. .

  (4) A pair of positioning pieces 13 project from the inner peripheral edge of the fixture body 11, and the outer surfaces of both positioning pieces 13 are brought into contact with the peripheral surface of the through hole Wb, so that the back side of the panel material Wa is provided. The instrument fixture 10 can be positioned. Therefore, it is possible to prevent the fixture fixture 10 disposed on the back side of the panel material Wa from moving significantly in the radial direction of the through hole Wb. Therefore, when the attachment member 16 is screwed to the nut 15, the movement of the instrument attachment 10 in the radial direction of the through hole Wb is minimized, and the screwing operation of the attachment member 16 to the nut 15 is facilitated.

  (5) A bulging portion 14 that bulges toward the center point P of the fixture body 11 is integrally formed at the center of the inner surface of each positioning piece 13, and a nut 15 is embedded in each bulging portion 14. For this reason, compared with the case where the bulging part 14 is protruded from the inner peripheral part of the fixture main body 11 alone, the strength of the connecting portion between the bulging part 14 and the fixture main body 11 can be increased. Therefore, since the mounting member 16 is screwed onto the nut 15, a large load is applied to the bulging portion 14, but by integrally molding with the positioning piece 13, problems such as deformation of the bulging portion 14 may be eliminated. it can.

  (6) By using the ruled hole 17, the through hole Wc having a size that allows the bulging portion 14 (the nut 15) to face the indoor side and the support surface 12 to be supported on the back surface of the panel material Wa can be easily formed. And it can form in panel material Wa reliably.

  (7) The fixture body 11 has a C-shape in which the outer peripheral edge and the inner peripheral edge are close to a perfect circle, and the opening width of the cutting part 11c (the interval between the first end part 11a and the second end part 11b) is narrow. . For this reason, for example, the opening width of the cutting part 11c is wider than that of the embodiment, and the area of the support surface 12 can be increased compared to the case where the fixture body 11 is formed in a semicircular shape. The instrument fixture 10 can be disposed in a stable state on the back side. Moreover, since the support surface 12 is widely secured even if the downward force is applied to the fixture 10 by pulling the fire alarm F downward, the fixture 10 is dropped from the through hole Wb. Can be prevented.

  (8) The attachment body 11 is provided with two sticking portions 18. For this reason, the fixture part 10 can be stuck to the panel material Wa by the sticking part 18, and the movement to the direction which the instrument fixture 10 floats from the back surface of the panel material Wa can be prevented. Therefore, even if the attachment member 16 is screwed in toward the nut 15, the instrument fixture 10 does not rise, and the attachment operation of the attachment member 16 can be easily performed.

In addition, you may change the said embodiment as follows.
(Circle) you may stick the fixture main body 11 on the back surface of the panel material Wa using an adhesive agent instead of an adhesive tape.
