しかしながら、前記特許文献１，２は、型鋼のフランジに取り付けた金具（固定具５，金物３）の「横溝」に天井材（天井板８，天井材２）を差し込んでいる点で共通するが、差し込みで行われるため、天井材端部の破損が生じやすいという問題があった。また、天井材の厚みや材質によって異なる金具を用意しなければならず、管理が面倒であった。
また、前記特許文献３では、横材２０に対してビス等で固定するため作業性が悪いという問題があった。 However, Patent Documents 1 and 2 are common in that the ceiling material (ceiling plate 8 and ceiling material 2) is inserted into the “lateral groove” of the metal fitting (fixture 5 and hardware 3) attached to the flange of the steel mold. Since it is performed by insertion, there is a problem that the end of the ceiling material is easily damaged. In addition, metal fittings that differ depending on the thickness and material of the ceiling material have to be prepared, which is cumbersome to manage.
Moreover, in the said patent document 3, since it fixed to the cross member 20 with a screw etc., there existed a problem that workability | operativity was bad.

そこで、本発明は、屋根の骨組として用いられる鋼材（屋根母屋）などを室内側から覆って天井美観を損なうことがなく、しかも天井化粧材を天井方向へ押し込む等の簡易な操作にて容易に取り付けることができる天井化粧構造を提案することを目的とする。 Therefore, the present invention covers the steel material (roof purlin) used as the frame of the roof from the indoor side without damaging the aesthetics of the ceiling, and easily by a simple operation such as pushing the ceiling decorative material toward the ceiling. The object is to propose a ceiling decorative structure that can be attached.

A ceiling decorative structure in which a ceiling decorative material is attached between support materials, wherein the support material has an upper horizontal piece portion attached to a fixture fixed to the upper flange of the mold steel in the attached state, and the upper horizontal piece A vertical piece portion extending downward from the portion and a lower horizontal piece portion extending from the lower end of the vertical piece portion in the length direction of the steel plate, and the lower surface of the ceiling decorative material is a decorative surface A decorative surface portion, a pressing piece portion that extends downward from the left and right sides of the decorative surface portion, and is disposed at least above the lower horizontal piece portion of the support material in the attached state; and a lower end of the pressing piece portion. Each having a fitting portion, A fitting is fixed to the upper flange of the steel, and the support is attached to the support, and the ceiling decorative material is arranged between the lower lateral pieces of the adjacent support materials, thereby fitting the fitting. The present invention proposes a ceiling decorative structure in which a portion is elastically fitted to a lower horizontal piece of the support member.

また、本発明は、前記天井化粧構造において、取付具は、型鋼の上フランジに取り付けられる連結部を備えると共に支持材が取り付けられる延在部を有することを特徴とする天井化粧構造をも提案する。 The present invention also proposes a ceiling decorative structure, characterized in that, in the ceiling decorative structure, the fixture includes an extension portion to which a support member is attached and a connecting portion that is attached to the upper flange of the mold steel. .

また、本発明は、前記天井化粧構造において、天井化粧材は、化粧面部の前端及び後端が折り上げられている天井化粧構造をも提案する。 The present invention also proposes a ceiling decorative structure in which the front and rear ends of the decorative face portion are folded up in the ceiling decorative structure.

また、本発明は、前記天井化粧構造において、天井化粧材は、嵌合部の下端に下方へ延在する固定部を有する天井化粧構造をも提案する。 In the ceiling decorative structure, the present invention also proposes a ceiling decorative structure in which the ceiling decorative material has a fixing portion extending downward at the lower end of the fitting portion.

本発明の天井化粧構造は、ウエブ、上フランジを有する複数の型鋼からなる構造材に対して適宜に取付具を固定することにより直交状に支持材を取り付けることができ、該隣り合う支持材間に天井化粧材を取り付けた構成である。
したがって、この天井化粧構造では、天井化粧材の化粧面部に、予め或いは施工時に各種の天井板や落下防止板等を載置させた状態で容易に固定することができるため、化粧面板部に載置させる天井板自体又は落下防止板自体には殆ど制限がなく、例えば天井板自体に成形誤差等があっても適用することができる。 The ceiling decorative structure of the present invention can attach a support material to a structural material composed of a plurality of steel molds having a web and an upper flange as appropriate, and can attach a support material in an orthogonal shape between the adjacent support materials. It is the structure which attached the ceiling decorative material to.
Therefore, in this ceiling decorative structure, it can be easily fixed to the decorative surface portion of the ceiling decorative material in a state where various ceiling plates or fall prevention plates are placed in advance or at the time of construction. There is almost no restriction on the ceiling plate itself or the fall prevention plate itself, and for example, the ceiling plate itself can be applied even if there is a molding error or the like.

また、取付具は、型鋼の上フランジに取り付けられる連結部を備えると共に支持材が取り付けられる延在部を有する場合には、天井化粧材を支持する支持材の取付箇所をこの取付具にて型鋼に形成することができる。 In addition, when the fixture has a connecting portion that is attached to the upper flange of the steel mold and has an extending portion to which the support material is attached, the mounting location of the support material that supports the ceiling decorative material is set by using this fixture.

本発明の天井化粧構造は、少なくともウエブ、上フランジを有する複数の型鋼からなる構造材に対し、直交状に延在するように複数の支持材が取り付けられ、隣り合う支持材間に天井化粧材が取り付けられたものであるが、型鋼の上フランジには適宜取付具が固定されているので、容易に支持材を（更にその後の天井化粧材も容易に）取り付けることができる。 The ceiling decorative structure of the present invention has a plurality of support members attached so as to extend orthogonally to a structural material made of a plurality of steel molds having at least a web and an upper flange, and the ceiling decorative material between adjacent support materials However, since a fixture is appropriately fixed to the upper flange of the mold steel, the support material (and the subsequent ceiling decorative material can be easily attached) can be easily attached.

前記支持材の取付対象である型鋼は、少なくともウエブ、上フランジを有するものであればよく、具体的には左右両方に上フランジを備えるＨ型鋼、Ｉ型鋼、左右の何れか一方のみに上フランジを備える溝型鋼、Ｚ型鋼等が相当する。
なお、これらの型鋼は、同じ型鋼の上フランジが同一方向に延在するように配設して構造材を形成していることが多いが、一部には異なる型鋼を組み合わせて用いていることもあるので、これらのケースを想定して高さレベルを統一して配設されている上フランジを本発明における支持材の取付部位（＝取付具を介して取り付けられる部位）とした。 The shape steel to which the support material is attached is only required to have at least a web and an upper flange, and specifically, an H-shape steel having an upper flange on both the left and right sides, an I-shape steel, and an upper flange on only one of the left and right sides. Corrugated steel, Z-shaped steel, and the like.
In many cases, these steel molds are arranged so that the upper flanges of the same steel molds extend in the same direction to form a structural material. Therefore, assuming these cases, the upper flange disposed at a uniform height level is used as the attachment portion of the support material (= the portion attached via the attachment tool) in the present invention.

前記取付具は、前述のように取付状態において型鋼の上フランジに取り付けられるものであり、前述のように異なる型鋼を組み合わせて用いるケースもあるので、複数種類の取付具を用いる場合もある。例えば後述する図示実施例では、Ｈ型鋼の上フランジに対して第１取付具を取り付け、溝型鋼の上フランジに対して第２取付具又は第３取付具を取り付けるようにしている。上フランジへの取付態様は、嵌合、係合、挟着等どのような手法（構成）を用いてもよい。なお、用いる取付具は、単一部材からなるものでも複数部材からなるものでもよく、特に複数部材からなる場合にはそれらをビス等で一体化させると共に支持材と連結するものが好ましい。 As described above, the fixture is attached to the upper flange of the mold steel in the attached state, and there are cases where different mold steels are used in combination as described above, and therefore, multiple types of fixtures may be used. For example, in the illustrated embodiment described later, the first fixture is attached to the upper flange of the H-shaped steel, and the second fixture or the third fixture is attached to the upper flange of the grooved steel. As a manner of attachment to the upper flange, any method (configuration) such as fitting, engagement, and clamping may be used. The fixture to be used may be a single member or a plurality of members, and in particular, in the case of a plurality of members, it is preferable to integrate them with screws or the like and connect them to a support material.

前記支持材は、取付状態において前記型鋼の上フランジに取り付けられた取付具に取り付けられる上方横片部と、該上方横片部から下方へ延在する縦片部と、該縦片部の下端から前記型鋼の長さ方向に延在する下方横片部とを有する。
なお、後述する図示実施例では、この支持材を、左右対称のハット状に成型した連続材を用いているが、それに限定されるものではなく、例えばユ型状に成形した連続材でもよい。即ちハット状の支持材では、縦片部として対向状の二面が存在し、各縦片部の下端にそれぞれ外側へ延在する下方横片部が形成される構成であり、取付具に対して「回転」で配設でき、その状態で仮設が行え、作業が容易であるという利点を有する。ユ型状の支持材では、縦片部は一面であって、その下端に左右に延在する下方横片部が形成される構成である。 The support material includes an upper horizontal piece portion attached to a fixture attached to the upper flange of the mold steel in an attached state, a vertical piece portion extending downward from the upper horizontal piece portion, and a lower end of the vertical piece portion And a lower horizontal piece extending in the length direction of the steel plate.
In the illustrated embodiment to be described later, this support material is a continuous material molded in a symmetrical hat shape. However, the present invention is not limited to this. For example, a continuous material molded in a U shape may be used. That is, in the hat-shaped support material, there are two opposing surfaces as the vertical piece portions, and a lower horizontal piece portion that extends outward is formed at the lower end of each vertical piece portion, and the fixture is Thus, it is possible to dispose it by “rotation”, and it is possible to perform temporary work in that state, and it is easy to work. In the U-shaped support material, the vertical piece is a single surface, and a lower horizontal piece extending left and right is formed at the lower end of the vertical piece.

前記天井化粧材は、下面側が化粧面となる化粧面部と、該化粧面部の左右からそれぞれ下方へ延在して少なくとも取付状態では前記支持材の下方横片部の上方に配置される押し込み片部と、該押し込み片部の下端に延設される嵌合部と、を有する構成である。
この天井化粧材は、前述のように隣り合う支持材の下方横片部間に取り付けられるものであるから、前記支持材の縦片部及び下方横片部を左右対称状に成型した形状のものを用いた場合には、後述する図示実施例のように左右対称状の部材として成形することができる。この場合には、部材の生産に関しても取付作業（取付方向の誤りを生じない）においても利点が大きいものとなる。 The ceiling decorative material includes a decorative surface portion whose lower surface side is a decorative surface, and a pushing piece portion that extends downward from the left and right sides of the decorative surface portion and is disposed above the lower horizontal piece portion of the support material at least in an attached state. And a fitting portion extending to the lower end of the pushing piece portion.
Since this ceiling decorative material is attached between the lower horizontal piece portions of adjacent support materials as described above, the vertical decorative piece portion and the lower horizontal piece portion of the support material are shaped symmetrically. Can be formed as a bilaterally symmetric member as in the illustrated embodiment described below. In this case, there is a great advantage in both the production of the members and the attachment work (no error in the attachment direction).

そして、本発明の天井化粧構造は、それぞれの型鋼に前記取付具を介して前記支持材を取り付け、隣り合う前記支持材の下方横片部間に、前記天井化粧材を配置させることにより、前記嵌合部を前記支持材の下方横片部に弾性的に嵌合させてなることを特徴とする。 And the ceiling decorative structure of the present invention attaches the support material to each mold steel via the fixture, and disposes the ceiling decorative material between the lower lateral pieces of the adjacent support materials. The fitting portion is elastically fitted to the lower horizontal piece portion of the support material.

以下、本発明の天井化粧構造に用いる取付具、支持材及び天井化粧材について、さらに詳細に説明する。 Hereinafter, the fixture, support material, and ceiling decorative material used in the ceiling decorative structure of the present invention will be described in more detail.

前記取付具は、前述のように取付状態において型鋼の上フランジに取り付けられるものであって、型鋼に応じて複数種類の取付具を用いる場合もある。
後述する図示実施例の第１取付具は、Ｈ型鋼の上フランジを対象部位とし、この上フランジは厚みが均一であることが多いので、当該上フランジの上面側と下面側にそれぞれ沿うように添設片を臨ませ、その基端をビス止めすることにより、Ｈ型鋼に挟着状に取り付ける態様（連結部）とし、更にその外側には横片状の延在部を設けている。
また、後述する図示実施例の第２取付具は、溝型鋼の上フランジを対象部位とし、この上フランジは先端が薄肉になっていることが多いので、当該上フランジの先端に引っ掛けた片とウエブに沿わせた片とをビス止めして一体化させることにより、溝型鋼に係合状に取り付ける態様（連結部）とし、更にその外側には横片状の延在部を設けている。
さらに、後述する図示実施例の第３取付具は、溝型鋼の上フランジを対象部位とし、前記第２取付具における「当該上フランジの先端に引っ掛けた片」に代えて水平片に非重合片を有する添設片を組み付けて当該上フランジを挟む構成とした。 As described above, the fixture is attached to the upper flange of the steel mold in the attached state, and a plurality of types of fixtures may be used depending on the steel mold.
The first fixture of the illustrated embodiment to be described later has an upper flange of an H-shaped steel as a target portion, and since this upper flange is often uniform in thickness, it is along the upper surface side and the lower surface side of the upper flange. By attaching the attachment piece and screwing the base end thereof, it is configured to be attached to the H-shaped steel in a sandwiched manner (connecting portion), and further, a lateral piece-like extension portion is provided on the outside thereof.
In addition, the second fixture of the illustrated embodiment described later has a grooved steel upper flange as a target part, and since the upper flange is often thin at the tip, a piece hooked on the tip of the upper flange and A piece along the web is screwed and integrated so as to be attached to the grooved steel in an engaging manner (connecting portion), and further, a lateral piece-like extending portion is provided on the outer side.
Further, the third fixture of the illustrated embodiment to be described later has a grooved steel upper flange as a target portion, and instead of the “piece hooked on the tip of the upper flange” in the second fixture, a horizontal piece is a non-polymerized piece. The attachment piece having the structure is assembled to sandwich the upper flange.

前記支持材は、前述のように取付状態において構造材を形成する型鋼の上フランジに取り付けられた取付具に取り付けられる上方横片部と、該上方横片部から下方へ延在する縦片部と、該縦片部の下端から前記型鋼の長さ方向に延在する下方横片部とを有する構成であって、それぞれの型鋼に直交状に延在するように取り付けられるものである。この支持材は、隣り合う型鋼にそれぞれ取り付けられた取付具間に亘って取り付けられ、型鋼と共に井型状の天井支持構造を構築するものである。 The support member includes an upper horizontal piece portion attached to a fixture attached to an upper flange of the steel mold that forms the structural material in the attached state as described above, and a vertical piece portion extending downward from the upper horizontal piece portion. And a lower horizontal piece extending in the length direction of the steel plate from the lower end of the vertical piece, and attached so as to extend orthogonally to each steel plate. This support material is attached over the fixtures respectively attached to the adjacent steel molds, and constructs a well-shaped ceiling support structure together with the steel molds.

前記上方横片部は、前述のように前記取付具を介して前記型鋼の上フランジに取り付けられるものであり、前述のように異なる型鋼に応じてそれぞれ異なる取付具を用いるケースもあるが、前記取付具の延在部と固定される横片を指す。
なお、前記ハット型の支持材では、後述する図示実施例のように前記取付具の横片状の延在部に跨がるように配してその上方横片部を延在部に重合させて固定している。 The upper horizontal piece is attached to the upper flange of the steel mold via the fixture as described above, and there are cases where different fixtures are used according to different steel molds as described above. The horizontal piece fixed with the extension part of a fixture is pointed out.
In the hat-type support material, as shown in the illustrated embodiment to be described later, the hat-shaped support member is arranged so as to straddle the horizontal piece-like extension portion of the fixture, and the upper horizontal piece portion is superposed on the extension portion. Are fixed.

前記縦片部は、前述のように前記上方横片部から下方へ延在するものであり、前記ハット状の支持材では対向状の二面が縦片部として存在し、前記ユ型状の支持材では一面のみが縦片部として存在する。
なお、特にハット型の支持材では、二面の縦片部の対向間隔が上方横片部の幅に相当するが、当該幅より僅かに小さく前記取付具の横幅を設定すれば、後述する図示実施例のように作業性にも優れた構成となるため、好ましい。 As described above, the vertical piece portion extends downward from the upper horizontal piece portion, and in the hat-shaped support material, two opposing surfaces exist as vertical piece portions, and the U-shaped In the support material, only one surface exists as a vertical piece.
In particular, in the hat-type support material, the facing distance between the vertical piece portions of the two surfaces corresponds to the width of the upper horizontal piece portion, but if the width of the fixture is set slightly smaller than the width, the illustration will be described later. Since it becomes the structure excellent also in workability | operativity like an Example, it is preferable.

前記下方横片部は、前述のように前記縦片部の下端から前記型鋼の長さ方向に延在するものである。ハット状の支持材では、各縦片部の下端にそれぞれ外側へ延在する下方横片部が形成され、ユ型状の支持材では、一面の縦片部の下端に左右に延在する下方横片部が形成される。
この下方横片部は、天井化粧材が取り付けられる部位であるから、後述する図示実施例のようにその先端が（リップ状に）上方へ折り曲げられていることが支持材自体の強度面でも、後述する天井化粧材の取付安定性の点でも好ましい。 As described above, the lower horizontal piece extends from the lower end of the vertical piece in the length direction of the steel plate. In the hat-shaped support material, a lower horizontal piece portion extending outward is formed at the lower end of each vertical piece portion, and in the U-shaped support material, the lower portion extending left and right at the lower end of the vertical piece portion on one side A lateral piece is formed.
This lower horizontal piece is a part to which the ceiling decorative material is attached, so that the tip is bent upward (in a lip shape) as in the illustrated embodiment described later, even in terms of the strength of the support material itself, This is also preferable in terms of mounting stability of the ceiling decorative material described later.

前記天井化粧材は、前述のように下面側が化粧面となる化粧面部と、該化粧面部の左右からそれぞれ下方へ延在して少なくとも取付状態では前記支持材の下方横片部の上方に配置される押し込み片部と、該押し込み片部の下端に設けられる嵌合部と、を有するものである。
この天井化粧材は、前記支持材の長さ方向に連続する長尺状でもよいが、所定長さを有する定尺材を複数並列状に配設するものでもよく、意匠性を継続的に維持でき、前述の挙動を可能とする材料であれば、例えば金属板や硬質樹脂板等の単一材料にて構成されるものでもよいし、例えば金網状の材料にボード状の材料を組み合わせた複数材料にて構成されるものでもよい。なお、前記金属板等に強度の向上を目的としてボード状の材料を組み合わせてもよいが、以降の複数材料にて構成される態様としては、金網状材料とボード状材料とを組み合わせたものとする。 As described above, the ceiling decorative material extends downward from the left and right sides of the decorative surface portion, and is disposed above the lower horizontal piece portion of the support material at least in the attached state. And a fitting portion provided at the lower end of the pushing piece.
The ceiling decorative material may have a continuous shape in the length direction of the support material, but a plurality of fixed-length materials having a predetermined length may be arranged in parallel, and the design property is continuously maintained. As long as it is a material that can behave as described above, it may be composed of a single material such as a metal plate or a hard resin plate, for example, or a plurality of combination of a wire mesh material and a board-like material It may be composed of materials. In addition, a board-like material may be combined with the metal plate or the like for the purpose of improving the strength, but as an aspect constituted by a plurality of subsequent materials, a combination of a wire mesh material and a board-like material is used. To do.

前記天井化粧材が前記金網状材料とボード状材料を組み合わせた複数材料にて構成される態様は、この天井化粧材の部位やこの天井化粧材が必要とする特性を何れか一方に全て負担させるのではなく、各材料に分担させる態様ということもできる。
化粧面部は、専らボード状材料に任せることにより強度を向上することができ、押し込み片部や嵌合部は、専ら金網状材料に任せるようにすればよい。言い換えれば、ボード状材料としては、化粧面部として必要な特性を有するものであれば、特にその材質を限定するものではなく、金網状材料としては、押し込み片部や嵌合部として必要な特性を有するものであれば、特にその材質を限定するものではない。 In the aspect in which the ceiling decorative material is composed of a plurality of materials obtained by combining the wire mesh material and the board-like material, any one of the parts of the ceiling decorative material and the characteristics required by the ceiling decorative material is borne. Instead of this, it can be said that each material is shared.
Strength can be improved by leaving the decorative surface portion exclusively to the board-like material, and the pushing piece and the fitting portion may be exclusively left to the wire mesh material. In other words, the board-like material is not particularly limited as long as it has the characteristics required as a decorative face part, and the wire mesh material has the characteristics required as a pushing piece part or a fitting part. If it has, the material in particular will not be limited.

前記化粧面部は、前述のように前記支持材間に亘る部位であって、後述する図示実施例では側面視が略平坦状（略水平状）に成形されているが、特にその形状について限定するものではない。
また、この化粧面部は、屋根面等の修復又は改修作業に際し、各種の金具類や破片物等の不慮の落下物をも受支することができることが望ましいので、例えばパンチングメタルや金属製メッシュ材などの金網状材料をこの天井化粧材の材料とするケースにおいても、金網状材料を単一材料の天井化粧材とする場合には、その孔部は部材等が通過しにくいものとすればよく、金網状材料を複数材料の一つとして用いる場合には、本質的にこの化粧面部を担当するボード状材料が部材等の通過を阻止するので、前記金網状材料の孔部には制限はなくどのようなものでもよい。 As described above, the decorative surface portion is a portion extending between the supporting materials, and in the illustrated embodiment described later, the side view is formed in a substantially flat shape (substantially horizontal shape), but the shape is particularly limited. It is not a thing.
In addition, it is desirable that this decorative surface portion can also receive unintentional falling objects such as various metal fittings and fragments when the roof surface is repaired or repaired. For example, a punching metal or a metal mesh material is used. Even in the case where the wire mesh material is a ceiling material made of a ceiling material, such as a wire mesh material, it is sufficient that the hole or the like does not easily pass through the hole. When the wire mesh material is used as one of a plurality of materials, the board-like material in charge of the decorative surface portion essentially prevents the passage of the member, etc., so there is no restriction on the hole portion of the wire mesh material. It can be anything.

また、前記天井化粧材の化粧面部の前端及び後端は、折り上げられていることが望ましい。即ちその場合には化粧面部の曲げ強度が高くなり、形状安定性も高くなるので、落下物を受支する強度も高いものとなる。なお、複数材料の金網状材料を、この化粧面部の補助として用い、その前端及び後端を折り上げ、その折り上げ片間にボード状材料を保持するようにしてもよい。 Moreover, it is desirable that the front end and the rear end of the decorative surface portion of the ceiling decorative material are folded up. That is, in this case, the bending strength of the decorative surface portion is increased and the shape stability is also increased, so that the strength for receiving the falling object is also increased. Note that a plurality of wire mesh materials may be used as an auxiliary for the decorative surface portion, the front end and the rear end may be folded, and the board-shaped material may be held between the folded pieces.

前記押し込み片部は、前述のように前記化粧面部の左右からそれぞれ下方へ延在して少なくとも取付状態では前記支持材の下方横片部の上方に配置される部位であって、その下端には嵌合部が設けられる。

However, the fitting portion provided at the lower end of the pushing piece is engaged with the tip of the lower lateral piece portion of the support member from the outside. Therefore, it is desirable that the lower end of the push-in piece part expands to the outermost side.

また、嵌合部の形状も、前記支持材の下方横片部の構成によって適宜に設定すればよいが、リップ（上向き片）を備えない下方横片部に対しては下方横片部に沿う横片の前端を折り返した形状に形成すればよいし、リップを備える下方横片部に対しては下方横片部及びリップに沿うＬ字状に形成すればよい。 Further, the shape of the fitting portion may be set as appropriate depending on the configuration of the lower horizontal piece portion of the support material. However, the lower horizontal piece portion that does not have a lip (upward piece) follows the lower horizontal piece portion. What is necessary is just to form in the shape which turned up the front end of a horizontal piece, and what is necessary is just to form in the L shape along a lower horizontal piece part and a lip with respect to the lower horizontal piece part provided with a lip.

なお、前記嵌合部の下端には、下方へ延在する固定部を設けるようにしてもよい。即ち該固定部にビス等の固着具を打ち込むことにより、嵌合部の固定はより強固に且つ確実なものとなる。 In addition, you may make it provide the fixing | fixed part extended below in the lower end of the said fitting part. That is, by fixing a fixing tool such as a screw into the fixing portion, the fixing of the fitting portion becomes stronger and more reliable.

この状態は、支持材２及び天井化粧材１を配設する前の状態であるが、取付具３Ｂ，３Ｃに形成される横片状の延在部３４２，３５２が支持材２の取付部となるため、前述のようにハット状の支持材２では、上方横片部２１を下にして下方から嵌合状に臨ませ、その状態で支持材２を回転させて（上方横片部２１を延在部３４２，３５２の上方に位置させて跨るように）配設でき、その状態で仮設を行うことができ、作業が容易である。 FIG. 5 shows that the second fitting 3B is attached to the grooved steel 4B, 4B arranged at both ends in the same manner as in FIG. 3B, and the third attachment is attached to the grooved steel 4B arranged in the center. A tool 3C is attached.
This state is a state before the support material 2 and the ceiling decorative material 1 are arranged, but the horizontal piece-like extending portions 342 and 352 formed on the attachment tools 3B and 3C are the attachment portions of the support material 2 and Therefore, as described above, in the hat-shaped support member 2, the upper horizontal piece portion 21 is faced down so as to be fitted from below, and the support member 2 is rotated in this state (the upper horizontal piece portion 21 is It can be disposed so as to be located above and extend over the extending portions 342 and 352, and temporary work can be performed in this state, and the work is easy.

したがって、この第２実施例でも、前記第１実施例と同様の効果を奏することができ、溝型鋼４Ｂに対し、適宜に取付具３Ｂ，３Ｃを固定することにより、溝型鋼４Ｂに直交状に延在するように複数の支持材２を取り付けることができ、隣り合う支持材２，２間に天井化粧材１を取り付けた構成であり、天井化粧材１の化粧面部１１に、予め或いは施工時に各種の天井板や落下防止板等を載置させた状態で容易に固定することができるため、化粧面部に載置させる天井板自体又は落下防止板自体には殆ど制限がなく、例えば天井板自体に成形誤差等があっても適用することができる。 Therefore, in the second embodiment, the same effect as that of the first embodiment can be obtained, and the fixtures 3B and 3C are appropriately fixed to the groove steel 4B so as to be orthogonal to the groove steel 4B. A plurality of support materials 2 can be attached so as to extend, and the ceiling decorative material 1 is attached between the adjacent support materials 2 and 2, and the decorative surface portion 11 of the ceiling decorative material 1 is preliminarily or during construction. Since various ceiling plates and fall prevention plates can be easily fixed in a state where they are placed, there is almost no restriction on the ceiling plate itself or the fall prevention plate itself to be placed on the decorative surface, for example, the ceiling plate itself Even if there is a molding error or the like, it can be applied.
