Abstract

PROBLEM TO BE SOLVED: To mount a sensor or the like into a position within a regulation on the lower side of a folding roof without damaging the folding roof. SOLUTION: An insertion piece 31 of an insertion implement 30 is inserted between an upper plate and a lower plate of a joint part A of the folding roof, and a shank is inserted through a cutout 43 of a plate part 41 of a clamping implement 40 to rotate and tighten a bolt 50 screwed into a threaded hole 35 of a base part 34 of the insertion implement 30, to thereby clamp the plate part 41 to the base part 34. A clamping piece 42 of the clamping implement 40 is thereby pressed to the lower face of the lower plate of the folded plate roof to clamp the lower plate by the insertion piece 31 and clamping piece 42, thus supporting a support 60 mounted with the sensor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folded plate roof in which, for example, a sensor or the like can be attached to the underside of the folded plate roof without directly piercing or screwing the same into the building. For mounting fixtures.

[0002]

2. Description of the Related Art When it is necessary to mount a sensor, for example, directly below a ceiling surface, in a building where the ceiling surface is a folded plate roof 1 as shown in FIG. Drilling or screwing directly into the
May cause a leak.

Conventionally, as shown in FIG. 10, a steel member (or a channel member) 3 is cut between two beams 2 and 2 supporting a folded-plate roof, and the both ends are cut off. The sensor 4 and the like were fixed on the lower surface of the steel material (or channel material) 3.

[0004]

However, a steel member (or a channel member) 3 is cut between the two beams 2 and 2 supporting the folded-plate roof 1 at the same length, and both ends thereof are fixed. However, in the conventional method of attaching the sensor 4 and the like to the steel material (or channel material) 3, the distance between the two beams 2 is large and the length of the steel material (or channel material) is not enough, so In some cases, it was not possible.

In addition, long steel materials (or channel materials)
3, the cost was high. In addition, in the construction of the detector, Article 23 of the "Fire Service Law" stipulates that "the lower end of the detector must be located within 0.3 m below the mounting surface". In the conventional method of mounting the sensor 4 on the lower surface of the channel material 3, since the height a of the folded plate roof 1 and the height b of the beam 2 are 0.3
In some cases, construction could not be performed at a position within m.

[0006] Also, since Article 23 of the "Fire Service Law Implementation Rules" states that "the detector of the sensor should not be tilted more than 5 degrees", the beams 2, 2, ... Since it is inclined at the same angle as the slope of the folded plate roof 1, a steel member (or a channel member) 3 fixed between the two beams 2 and 2
Are also inclined at the same angle.

For this reason, it is necessary to mount the sensor 4 at an angle with respect to the lower surface of the steel material (or channel material) 3 so that the lower surface of the sensor 4 satisfies this rule, and this mounting work is extremely complicated.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and for a folded plate roof, for example, a sensor or the like can be attached to a position within a rule below the folded plate roof without damaging the folded plate roof. It is intended to provide a fixture.

On the upper portion of the flat plate portion 41, the plug 30
In order to insert the bolt 50 screwed into the tap screw hole 35 of the base 34 of the base 34 from the side in the horizontal direction, the width in the lateral direction opened on the side is larger than the axis of the bolt 50, and the bolt 5
A notch smaller than the outer diameter of the 0 head 51, for example, a slit 43 is provided.

At the lower end of the flat plate portion 41 of the holding tool 40,
For example, the support 60 for mounting the sensor 70
The caulking 44 is attached so that it can rotate to an arbitrary angle if a force is applied by hand, and does not rotate at that angle if you release your hand. It should be noted that the bolts and nuts may be tightened and fixed at an arbitrary rotation angle.

The support member 60 has, for example, an L-shape obtained by bending a rectangular metal plate at a right angle as shown in FIG. 1, and the vertical plate 61 is provided at the lower end of the flat plate portion 41 of the holding member 40 as described above. At both ends in the longitudinal direction of the horizontal plate 62, mounting holes 63, 63 for fixing the detector 70 with the tapping screw 52 or the like are provided.

Next, a method of using the folded-plate roof fixture will be described. First, the tip of the horizontal piece 31b of the insertion piece 31 is folded into the folded plate roof 1 in a temporarily fixed state in which the tip of the bolt 50 is slightly screwed into the tap screw hole 35 of the base 34 of the insertion tool 30.
Between the upper plate and the lower plate of the joint portion A, that is, between the inclined portion 11c of the roof plate 11 and the inclined edge portion 11'b of the roof plate 11 '. Then, as shown in FIG. 3, the horizontal portion 11a on the upper side of the joint A is further pushed in.
Piece 3 of the insertion piece 31 between the lower horizontal portion 11'a
1b is inserted, and the inclined piece 31a of the insertion piece 31 is inserted between the upper inclined part 11c and the lower inclined edge 11'b.

Next, as shown in FIG. 3, with the sensor 70 mounted on the lower surface of the horizontal plate 62 of the supporter 60 by the tapping screws 52, 52 in the mounting holes 63, 63, the flat plate portion of the holder 40 is held. Opening 4 of slit 43 above 41
3a is aligned with the shaft portion of the temporarily fixed bolt 50 screwed into the tap screw hole 35 of the base portion 34, and the shaft portion of the bolt 50 is inserted horizontally and horizontally at the innermost portion of the slit 43, The flat plate portion 41 of the holding device 40 is inserted between the two stopper edges 36 and 37 on both sides of the base portion 34 of the insertion device 30.

Then, the bolt 50 is rotated to hold the holding member 4.
0 by tightening the flat plate portion 41 to the base portion 34 of the plug-in device 30, so that the horizontal portion 11 ′ a and the inclined edge portion 11 ′ b of the lower roof plate 11 ′ are connected to the horizontal piece 42 b and the inclined piece 42 a
, And pressed between the horizontal piece 31b and the inclined piece 31a of the insertion piece 31.

If the holding member 40 is made of an elastic metal plate, and its horizontal piece 42b is slightly upward with its tip end side, the lower plate is pressed upward by the elastic return force in the holding state shown in FIG. Therefore, the pinching is further ensured.

In this manner, the sensor 70 and the like can be attached very easily using the joint A of the folded-plate roof 1, and furthermore, since the sensor 70 and the like are directly attached to the upper part of the folded-plate roof 1, the above-mentioned " The provisions of Article 23 of the Fire Service Law, "The lower end of the sensor must be located within 0.3 m below the mounting surface" can be easily cleared.

Further, as described above, the support member 60 can be fixed in a state rotated at a desired angle with respect to the holding member 40 by the caulking 44 or the bolt and the nut. By twisting it, the lower surface of the sensor can be horizontal regardless of the slope of the roof,
The provision of Article 23, "The detector of the sensor should be provided so as not to be inclined more than 5 degrees" can be easily cleared.

Not only the sensor, but also a hanging bolt, a wiring box, and any other object can be attached depending on the structure of the support 60. For example, as shown in FIG. A tapped screw hole 65 may be provided so that the upper end of a suspension bolt (not shown) can be screwed in and attached.

As shown in FIG. 4, the holding member 40 is formed of an elastic metal plate, and the horizontal portion 42b of the holding member 40 is formed.
