DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. First Embodiment FIG. 2 is a perspective view showing a folded-plate roof mounting bracket 1 (hereinafter, referred to as a mounting bracket) in a state where the receiving bracket 15 is not mounted. As shown in FIG. A metal body 3 formed by bending a metal plate and fixed on the beam 2 (see FIGS. 1 and 4); and a sword-point bolt 4 erected at the center of the upper surface of the metal body 3. ing.

The above-mentioned metal fitting body 3 is formed to have a substantially arch-shaped cross section and a shape that is long in the front-rear direction. The fixing portions 6 and 6 are fixed to the upper surface of the fixing member 2 by welding. In addition, the upper part is formed in an equi-leg trapezoid shape in which the lower part is slightly wider, and is set as a fitting part 8 into which a joiner 7 having a shape as shown in FIG. That is, both side portions in the front-rear direction of the metal fitting main body 3 sandwiching the sword point bolt 4 are the joiner connecting portions 9, 9.

Here, the joiner 7 shown in FIG. 3 will be described. This joiner 7 is also formed by bending a metal plate. As shown in FIG. 4, each of the lower portions has a U-shaped locking groove 7 b for locking the ceiling plates 10, 10 as shown in FIG. 4. It is long corresponding to the width of. The joiner 7 is fitted to the joiner connecting portions 9 of the metal fitting body 3 to fix the ceiling plates 10 and 10 to the locking grooves 7b and 7b.
7B, the ceiling plates 10, 10 are laid on the upper surface of the beam 2.

Incidentally, as shown in FIG.
There is a gap between the fitting part 8 and the fitting part 7a of the joiner 7 (a gap formed by different inclination angles), but this is a fitting of the joiner 7 to the joiner connecting parts 9, 9. This is because the joining is facilitated and the above-mentioned ceiling plates 10 and 10 formed of glass wool or the like are firmly locked.

The above-mentioned sword-point bolt 4 is provided with a cylindrical main body 1.
1 and a screw portion 12, and an intermediate portion of the main body portion 11 is inserted into a fixing hole 13 formed on the upper surface of the fitting main body 3, and is fixed by welding. And the length of the main body 11 is
The lower end surface is in contact with the upper surface of the beam 2 and the upper end surface is a folded plate roof 14,
14 is the length to reach the position required for mounting. The main body 11 may be solid or hollow.

The screw portion 12 is formed to have a smaller diameter than the main body portion 11 so that the receiving fitting 15 as shown in FIG. 3 can be mounted. The tip of the screw portion 12 may not be sharp as shown, but may be flat.

The above-mentioned metal fitting 15 has a rectangular horizontal portion 15b having an insertion hole 15a inserted into the screw portion 12 at the center.
The folded plate roof 14,
14 are formed by inclined portions 15c, 15c which extend downward by a predetermined angle corresponding to 14. This fitting 15
Is intended to stably receive the folded-plate roofs 14, 14, so it is sufficient if there is at least a surface to receive it.
The above-mentioned inclined portions 15c, 15c may not be provided, and may be a simple washer.

In the mounting bracket 1 formed as described above, when mounting the folded-plate roofs 14, 14, first, the ink is printed on the upper surface of the beam member 2, and the fixing portions 6, 6 of the bracket main body 3 are adjusted accordingly. It is fixed at a predetermined position on the beam 2 by welding. Since the mounting bracket 1 has a left-right symmetrical shape, the alignment may be performed, for example, based on one of the two left and right fixing portions 6 and 6. Welding is performed between the fixing portions 6 and 6 of the metal fitting body 3 and the beam 2, and between the lower end of the pointed bolt 4 and the beam 2.
And between This is to increase the strength, and the welding at these two points is combined with the fact that the sword-point bolt 4 is inserted into the fixing hole 13 formed on the upper surface of the fitting body 3, so that it is resistant to a load from above. In addition, it is possible to sufficiently cope with the force in the left-right direction.

FIG. 1 is an explanatory view showing an example of the work of attaching the folded-plate roofs 14, 14 according to the interval between the peaks of the folded-plate roofs 14, 14 and the width of the ceiling plates 10. It is good to use not only the above-mentioned mounting bracket 1 but also ordinary folded-plate roof mounting bolts 17. The folded plate roof mounting bolts 17, 17 are formed by forming a screw 17b at the tip of a bolt body 17a, and a flange-shaped receiving portion 17c is integrally formed between the bolt body 17a and the screw 17b.

After the mounting bracket 1 is fixed, the metal fitting body 3
The joiner 7 is connected to the joiner connecting portions 9 on both sides in the front-rear direction.
Are fitted so that the joiners 7 are bridged between the beam members 2 arranged in parallel. Then, drop ceiling boards 10 ...
The ceiling plates 10 are locked in the locking grooves 7b, 7b of the joiners 7, and finally, the folded plate roofs 14, 14 are mounted via the sword-point bolts 4 erected on the upper surface of the fitting body 3. This attachment is performed by attaching a metal fitting 15 to the upper end surface of the main body 11 of the sword tip bolt 4.
After that, the folded roofs 14 and 14 are covered and the wool packing 18 and the washer 19 are
Are inserted and tightened using the nut 20 (see FIG. 4). When the folded-plate roofs 14 are attached, the lower surfaces of the folded-plate roofs 14 press the upper surfaces of the ceiling plates 10 locked by the joiners 7.

In the work of mounting the folded-plate roofs 14, 14, the locking of the ceiling plates 10 and the mounting of the folded-plate roofs 14, 14 may be performed sequentially from one end and substantially synchronously. Is good. The folded-plate roofs 14 may be attached without locking the ceiling plates 10 as described above.

As described above, in the mounting bracket 1, the metal fitting body 3 is formed in a sectional shape corresponding to the joiner 7, so that
It is smaller and less bulky than when it is formed corresponding to the folded roofs 14,14. Therefore, storage and transportation of the mounting bracket 1 can be easily performed. Furthermore, it is inexpensive because of its simple structure. Moreover, when this mounting bracket 1 is used,
A folded plate roof structure having a sound absorbing and heat insulating effect can be easily obtained.

Further, since the mounting bracket 1 is low in bulk, the mounting bracket 1 is never deformed by an unexpected external force during storage or transportation, and can be fixed as desired.

Further, although the number of parts required for mounting the folded-plate roofs 14 and 14 is small and the parts management and the mounting work are easy, the metal fitting body 3 is formed in a substantially arch shape, so that it can be viewed from above. It has high strength against loads. In addition, since the strength of the mounting bracket 1 itself is high and the ceiling plates 10 are pressed down by the lower surfaces of the folded roofs 14, 14, an extremely strong folded roof structure is obtained.

(Other Embodiments) The mounting bracket 1 shown in FIG. 5 (showing a state in which the receiving bracket 15 is not mounted) has both ends of the metal fitting body 3 bent inward and slightly wider at the lower end. The fixing pieces 21 and 21 having the fixing surface 21a (fixing portion) are formed. Also, sword bolt 4
Is formed in the shape of a prism. The fixing of the sword point bolt 4 to the metal fitting body 3 is performed in addition to the upper surface corresponding to the metal fitting body 3, the lower end face of the sword tip bolt 4,
21.

The mounting bracket 1 thus configured has the fixing surfaces 21a, 21a, so that the fixing on the beam member 2 can be performed more stably, and the main body 11 of the sword bolt 4 has a prismatic shape. As a result, the sword tip bolt 4 is prevented from rotating, and the strength can be further increased. FIG.
Is a front view showing another example of the fitting main body 3, and as shown in this figure, the fixing pieces 21 and 21 may be bent outward when they are formed.

Further, as shown in FIG.
Holding portions 2 at both ends of the metal fitting body 3 so as to sandwich the lower end of the
2, 22 may be provided. The holding portions 22 are formed corresponding to the shape of the pointed bolt 4. That is, if the main body 11 of the sword tip bolt 4 is cylindrical, the holding parts 22 and 2
2 is formed so that one of the cross sections is substantially semicircular,
If the main body 11 of the sword bolt is a square pole, the holding portion 2
2, 22 are formed such that one of the cross sections has a U-shape. When formed in this manner, the sense of unity between the bracket main body 3 and the sword bolt 4 is further improved, and a mounting bracket having higher strength can be obtained. Further, the sword point bolt 4 may be erected from the upper surface of the metal fitting body 3.
