Abstract

PROBLEM TO BE SOLVED: To provide an envelope to be commonly used for roof and ceiling without generating damage and sort in the lower surface even in the case where the lower surface side is slid on the floor surface or the ground. SOLUTION: A lower surface of a band-shape part 6g made of a long size metal plate to be fixed to a beam 4 so as to be used as an envelop 6, which is to be commonly used for roof and ceiling, is formed with a recessed fitting surface 6h, which is recessed upward from both side parts of the band-shape part 6g. The generation of damage and sort in the lower surface of the envelope 6 is thereby prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an enclosure fixed to a beam of H-shaped steel or the like and used as a roof material for a roof and a ceiling.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. 5-209449 discloses a beam of a building made of H-shaped steel, to which an outer enclosure made of a metal plate is fixed via a fitting, and which constitutes a roof and a ceiling.
And the utility model registration No. 3008380 are disclosed in the specification and drawings.

[0003]

An outer enclosure made of a metal plate used as a roofing material or an outer wall material usually has an upper surface exposed to the outside and a lower surface fixed to a base material, so that the lower surface is a person. It is never exposed to the eye. Therefore, when handling the outer enclosure, the upper surface of the enclosure is treated carefully so as not to damage it, but the lower surface is often pulled or roughly handled by the floor or the ground, and therefore the outer enclosure is The lower surface of is often scratched or dirty. However, if the outer enclosure is fixed to a beam such as H-shaped steel that also serves as a roof and a ceiling, the lower surface of the outer enclosure is visible from inside the building, and the lower surface is scratched or dirty. However, there was a problem that the ceiling became unsightly. An object of the present invention is to solve the above problems.

[0004]

In order to achieve the above object, the present invention provides a strip portion (6g) and both sides of the strip portion (6g).
In an enclosure made of a metal plate having upwardly projecting rising walls (6a) (6b) for joining with another outer enclosure, the rising wall (6a) is provided on the lower surface of the strip (6g). The concave surface (6h) is formed so as to be drawn upward from the lowermost end of (6b).

[0005]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 3, 2 is H
It is a large beam made of shaped steel, and a small beam 4 made of H-shaped steel is fixed to the large beam. Reference numeral 6 denotes an outer enclosure made of a strip-shaped metal plate that also serves as a roof and a ceiling. A plurality of outer enclosures are arranged under the beam 4, and the rising walls 6a and 6b are provided on both side edges of each outer enclosure 6.
Are formed. One rising wall 6 of the outer enclosure 6
An engaging portion 6e including a horizontal portion 6c that bends outward and a hanging portion 6d that bends downward is formed in the upper portion of a, and an engagement portion including a horizontal portion that bends inward is formed in the other rising wall 6b. The part 6f is formed.

The strip-shaped portion 6g sandwiched by the rising walls 6a and 6b of the outer enclosure 6 is formed in a curved shape projecting in the upper surface direction, and the curved surface substantially entirely covers the lower surface of the strip-shaped portion 6g. A recessed surface 6h is formed. Reference numeral 8 denotes a mounting member, as shown in FIG. 1, which includes a fitting portion 8a formed by bending a metal plate into a U-shape so as to be detachable and press fit to the lower horizontal portion 4a of the beam 4. The fitting portion 8a includes a mounting portion 8b that is bent at a right angle and integrally formed with a side portion of a lower portion 8a 'of the fitting portion 8a.

The mounting method 8b is provided with a bolt insertion hole 10 which is an elongated hole for mounting the outer enclosure.
Next, the work of attaching the outer enclosure will be described. The pair of outer enclosures 6 and 6 are arranged adjacent to each other, and the engagement portion 6f of the one outer enclosure 6 is fitted to the engagement portion 6e of the other outer enclosure 6 so that the one outer enclosure 6 The rising portion 6b of the above is brought into contact with the rising portion 6a of the other outer casing 6 with their bolt insertion holes aligned.

Next, a pair of outer enclosures 6 and 6 whose rising walls are joined to each other are arranged below the beam 4 at a right angle thereto. Next, the fitting portion 8a of the mounting bracket 8 is press-fitted into the lower horizontal portion 4a of the beam 4, and the bolt insertion hole 10 of the mounting piece 8b is inserted into the rising wall 6 of the outer enclosures 6 and 6 that overlap each other.
Align with the bolt insertion holes of b and 6a.

Next, the rising walls 6b, 6 of the outer enclosures 6, 6
a, a bolt 12 is inserted into the bolt insertion hole 10 of the mounting piece 8b, and a nut 14 is screwed into the bolt 12 so that the rising walls 6b and 6a adjacent to each other of the pair of envelopes 6 and 6 are
It is fixed to the mounting piece 8b of the mounting bracket 8. The rising walls 6a, 6b of the outer enclosure 6 are attached to the rising walls 6b, 6b of the other outer enclosures 6,
6a are engaged with each other by engaging the engaging portions 6e and 6f, and are sequentially joined laterally as shown in FIG. 2, and this joining portion is attached to the beam 4 via the mounting bracket 8 in the above-described manner. Fix it.

Even if the lower part of the outer envelope 6 is rubbed against the floor during the above-mentioned work, since the concave face 6h is formed on the lower surface of the outer envelope 6, the concave face 6h is scratched. It doesn't get stuck. The concave surface of the lower surface of the outer envelope body 6 is not limited to the curved shape as shown in FIG. 5, but as shown in FIG.
The step portions 16 and 16 may be formed in the vicinity of both sides of i to form the recessed surface 6h formed of a flat plate surface.

[0011]

As described above, according to the present invention, since the recessed surface is formed on the lower surface of the strip-shaped portion of the outer envelope, even if the lower side of the outer enclosure is rubbed against the floor surface or the like, the lower surface of the strip-shaped portion is scratched. It does not get dirty. Therefore, the present invention can provide an optimal enclosure as a roofing material that serves as both a roof and a ceiling.
