Description

[Detailed explanation of the invention] [Industrial field of application] The present invention is designed to install lighting equipment on the indoor side of a large mountain-shaped roof.
This invention relates to a hanging structure for large mountain-shaped roofs that allows hanging items such as air conditioning ducts and piping to be easily and quickly attached.

[Conventional technology and its problems]

The conventional hanging structure for large mountain-shaped roofs is to provide holes for fasteners such as bolts at appropriate locations in the interior decorative board material, and use fasteners at the hole locations to attach lighting equipment, air conditioning ducts, etc.
It was used to hang things such as piping.

However, the work on the above structure is extremely tedious and is usually performed at height, making it difficult and dangerous.

In addition, since the decorative interior panel material is extremely thin, the hanging objects are limited to lightweight objects.

[Means for solving problems]

Therefore, as a result of intensive research in order to solve the above-mentioned problems, the inventor has developed the present invention, in which the reinforcing bones are fixed at predetermined intervals on the back side of the roof skin material. At the lower end position, the interior decorative board material is fixed via a fastener consisting of bolts and nuts.
By creating a hanging structure for a large chevron roof with a hanging fitting attached to the screw part on the lower side of the fastener with a nut, lighting equipment can be attached to the indoor side of the large chevron roofing material.
Air conditioning ducts, piping, etc. can be hung easily and quickly.
Moreover, it is possible to hang relatively heavy objects, thus solving the above-mentioned problems.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 7.

A is a large chevron roofing material with a long span, and a plurality of these large chevron roofing materials A are installed on the upper part of a structure to form a large chevron roof (see Fig. 1).

This large-sized chevron-shaped roof material A is formed from a long roof skin material 1 having a substantially chevron-shaped cross section and a strut 2 (see FIG. 1).

The roof skin material 1 has a bottom portion 1 extending outward from both lower ends of a mountain-shaped portion 1a formed in a substantially trapezoidal mountain shape in cross section.
b and 1b are bent.

A plurality of reinforcing bones 2, 2, . . . are fixed to the back surface of the roof skin material 1 in the longitudinal direction at predetermined intervals.

This force bone 2 includes oblique bone 2b,
2b, which form a trapezoidal mountain shape (see FIGS. 1, 5, and 6).

From both lower ends of the oblique bones 2b, 2b, bottom bones 2c, 2c consisting of a horizontal part and an inclined part are formed outwardly, and the bottom bones 2c, 2c have an L-shaped cross section on the lower surface of the bottom bones 2c, 2c.
The shaped fittings 2d, 2d are fixed symmetrically (see FIGS. 1, 2, and 3).

The top bones 2a and oblique bones 2b and 2b of the force bones are in contact with the back surface of the mountain-shaped portion 1a of the roof skin material 1, and the bottom bones 2c and 2c of the force bones 2 are in contact with the bottom portions 1b and 1b of the roof skin material 1, respectively. In this way, a stiffener 2 is fixed to the roof skin material 1.

B is interior decorative board material, and large-sized chevron roof material A
(See Figure 1).

Specifically, the interior decorative board material B is composed of an upper parting member 3 and a lower parting member 4.

The upper parting member 3 is formed into a substantially trapezoidal mountain shape, and inclined pieces 3b, 3b are bent outwardly and downwardly from both sides of the flat main plate 3a, and from the lower ends of the inclined pieces 3b, 3b, a cross section of approximately L-shaped bottom piece 3
c and 3c are bent (Figs. 1 and 5).
(see Figure 6).

The lower parting member 4 has an engaging side portion 4b formed at one end of a flat main plate 4a, and a gutter-shaped ceiling plate receiving portion 4c formed at the other end.

Of the interior decorative board material B, the upper parting member 3 is fixed to the top bone 2a of the brace 2, and the lower parting member 4 is fixed to the L-shaped metal fittings 2d at both lower ends of the brace 2 (Fig. 2, (See Figures 3, 5, and 6).

A fastener C is used to attach the interior decorative board material B to the upper brace 2.

As shown in FIG. 4, this fastening tool C has threaded portions 6a, 6a formed on the upper and lower sides, and a nut portion 6 in the middle.
It is composed of a bolt 6, a nut 7, and a cylindrical body 8.

To explain the case of using this fastener C to fix the lower parting member 4 to the L-shaped fittings 2d, 2d at both lower ends of the brace 2, first, the horizontal part of the L-shaped fitting 2d and the lower parting member 4 are fixed. The cylinder body 8 is interposed between the cylinder body 8 and the main plate 4a, and then the threaded part 6a at the upper part of the bolt 6 is passed through the main plate 4a of the cylinder body 8 and the L-shaped metal fitting 2d, and the nut 7 is tightened to the upper end of the cylinder body 8. shaped metal fittings 2d
The lower parting material 4 is fixed to the (Fig. 3, 4)
(See the solid line in the figure).

In this way, with the lower parting member 4 attached, the threaded portion 6a on the lower end side of the bolt 6 is
However, it stands out for a relatively long time.

Further, the mounting structure of the upper parting member 3 is also the same as that of the lower parting member 4 described above (see the chain line portion in FIG. 4).

In addition, the installation structure of the upper parting member 3 and the lower parting member 4 is ultimately the same as described above, but the order of installation is changed as appropriate, and the upper parting member 3 and the lower parting member 4 are attached to the bolt 6 as a reference. The parting member 4 may be attached, and the L-shaped metal fittings 2d at both lower ends of the brace 2 may be attached to this via the cylindrical body 8.

Also, although not shown, a case where the upper end (threaded portion 6a end) of the bolt 6, which is simply shaped like a bolt shaft, is fixed in advance to the top bone 2a of the force bone 2 and the L-shaped fitting 2d in a substantially perpendicular manner by welding or the like. When attaching the interior decorative board material B, it is only necessary to tighten the nut 7 to the lower threaded portion 6a of the bolt 6, that is, to the upper parting member 3 or lower parting member 4 side.

A ceiling board 5 is attached between the upper parting member 3 and the lower parting member 4 of the interior decorative board material B attached to the large-sized chevron-shaped roof material A.

Specifically, the upper end of the ceiling board 5 is inserted between the roof skin material 1 and the side part of the upper parting member 3, and the lower end of the ceiling board 5 is placed on the ceiling board receiving part 4c of the lower parting member 4. (See Figure 1).

Then, a hanging metal fitting is attached to the lower threaded part 6a of the bolt 6 protruding from the upper parting material 3 or lower parting material 4 of the interior decorative board material B of the large-sized chevron-shaped roofing material B on which the large-sized chevron-shaped roofing material A is attached. 9 is fixed (see Figure 1).

This hanging fitting 9 consists of a connecting part 9a and a hanging part 9b, and the connecting part 9a and hanging part 9b are joined by a shaft rod.

The connecting portion 9a is specifically a flat plate piece, in which a bolt hole 9c for the screw portion 6a hole located below the bolt 6 is provided. Further, as a specific example of the hanging part 9b, it is formed in a ring shape for hanging a hanging object 10 such as a pipe (see FIG. 2, FIG. 3, etc.), As shown in the figure, there is one in which a U-shaped bolt is inserted into a hole provided in a plate piece, and by tightening a nut, it is possible to fix even pipes with slightly different shaft diameters.

Another example of the hanging garment 10 is one in which the hanging garment 10 is a lighting fixture to which a fluorescent light, a light bulb, etc. can be attached (see FIG. 5).

The upper parting material 3 or the lower parting material 4 of the interior decorative board material B is inserted into the bolt hole 9c of the connecting part 9a of the hanging fitting 9.
The lower screw portion 6a of the bolt 6 protruding from the back surface (indoor side) is penetrated, and the hanging fitting 9 is attached to the large chevron roof by screwing the nut 7c.

[Effect of idea]

In the present invention, bolts 6 and nuts 7 are installed at the upper and both lower end positions of the ribs 2 of the large mountain-shaped roof material A, which has the ribs 2 fixed at predetermined intervals on the back surface of the roof skin material 1.
The interior decorative board material B is fixed through a fastener C consisting of a threaded portion 6a protruding below the fastener C.
In addition, by adopting a large chevron-shaped roof hanging structure in which the hanging fittings 9 are attached with nuts 7, first of all, hanging objects 10 such as lighting equipment, air conditioning ducts, piping, etc. can be attached easily and quickly. However, even if the second hanging object 10 is relatively heavy, it can be hung firmly.

To explain the above effect in detail, in order to hang objects such as lighting equipment, air conditioning ducts, and piping on a conventional large-sized chevron roof, for example, mounting holes are provided in the interior decorative board material of the large-sized chevron roof, and bolts, etc. The hanging item was hung using a fastener. However, this work is difficult and dangerous because it is usually performed at high places and requires heavy tools such as electric drills.

However, in the present invention, the threaded portion 6a of the bolt 6 is already protruding from the attachment point of the interior decorative board material B at the appropriate place for hanging lighting equipment, air conditioning ducts, piping, etc. of the large-sized chevron roofing material A, and this threaded portion 6a is By attaching the hanging fitting 9 with the nut 7, the hanging object 1
0 can be hung extremely easily.

That is, the connecting portion 9 of the hanging fitting 9 can be attached without any processing to the interior decorative board material B of the large-sized chevron roof material A.
By screwing a into the threaded part 6a of the bolt 6 protruding from the attachment point of the interior decorative board material B with the nut 7, lighting equipment, air conditioning ducts, piping, etc. can be hung, improving work efficiency and making it easier to use electric drills, etc. Since no heavy tools are required, the work is safe and the burden of working at heights can be reduced.

Next, since the interior decorative board material B was fixed to the upper and both lower end positions of the force bone 2 via the fasteners C, the bolt 6 was fixed to the top bone 2a or the L-shaped metal fitting 2d of the force bone 2. The bolts 6 are provided at the strongest positions of the large-sized chevron-shaped roofing material A, and therefore it is possible to hang relatively heavy hanging objects 10 such as large ducts and pipes.

Note that if the hanging portion 9b of the hanging fitting 9 is used properly according to various uses, it is possible to hang an electric fan, a speaker, etc. in addition to the pipes, air conditioning ducts, and lighting equipment in the embodiment.
