(A) It is sectional drawing which shows the state which attached the decorative cover in the ceiling makeup | decoration structure of 1st Example, (b) The side sectional view, (c) The expanded sectional view which shows the used decorative cover.

  In the ceiling makeup structure of the present invention, a support material including at least a web and a lower flange provided at a lower end of the web is attached to a ceiling base material at predetermined intervals, and a ceiling makeup material is attached between the support materials. is there.

As described above, the support member is attached to the ceiling base, and is configured to include at least the web and the lower flange provided at the lower end of the web.
The support material may have a lower flange which is a mounting portion of the ceiling decorative material on the left and right, or may have it on only one of the left and right. The support material may be formed by bending various metal plates or the like, or may be formed by extrusion molding or the like, and the manufacturing method thereof is not particularly limited.

  In particular, a lateral surface portion in which a supporting member is fixed to a ceiling substrate as in the illustrated embodiment described later, a web in which the left and right sides of the lateral surface portion are folded, and a lower flange formed by bending the lower end of the web outward. In the case of a left-right symmetrical member having the above, since the ceiling decorative material attached between the above-mentioned adjacent support members is also a left-right symmetrical member like the above-mentioned support member, its mounting work is also performed during its manufacture. In that case, it will be extremely efficient.

The web of the support material has the lower flange at the lower end, and may be provided on each of the left and right sides of one support material, or may be provided with a web having only one surface. The former aspect has a configuration having one lower flange that extends outward on either one of the left and right sides, and the latter aspect has two lower flanges that extend outward on both the left and right sides. It is a composition.
It is desirable to form a plurality of openings in this web, but this opening not only contributes to the weight reduction of the member, but also makes it possible to use a cosmetic material that hides the portion through which wiring and the like and the anchors located between the webs are hidden. It is used as a mounting portion, a mounting portion for a decorative material that hides the support material itself, a mounting portion for a device of an illumination lamp, and the like, and the shape thereof is not particularly limited to a circular shape or an elliptical shape.

Since the support member is attached to the ceiling substrate as described above, a horizontal surface portion fixed to the ceiling substrate is provided at the upper end of the web. For example, if the ceiling substrate is flat, the horizontal surface portion is also flat. It may be formed into a shape.
Further, the ceiling base refers to a lower surface formed of RC (reinforced concrete) or the like, and is generally flat, but is not particularly limited, and is used for attaching the support material in advance. You may make it form a hole.

The ceiling decorative material is a decorative surface portion whose lower surface side is a decorative surface, and a fitting portion that extends downward from the left and right of the decorative surface portion and is disposed above the lower flange of the support material at least in the attached state, And an engaging portion provided at a lower end of the fitting portion.
Since this ceiling decorative material is attached between the adjacent support materials as described above, it can be formed as a bilaterally symmetrical member as in the illustrated embodiment described later. In this case, the advantages are great both in the production of the members and in the mounting work (there is no error in the mounting direction).

  The ceiling finishing material may be a long shape continuous in the length direction of the support material, but may be one in which a plurality of fixed length materials having a predetermined length are arranged in parallel, and the design is continuously maintained. It is possible to use a single material such as a metal plate or a hard resin plate as long as it is a material that enables the above-mentioned behavior. For example, a porous material is combined with a board-shaped material. It may be composed of a plurality of materials. It should be noted that a board-shaped material may be combined with the metal plate or the like for the purpose of improving strength, but as a mode composed of a plurality of materials thereafter, a combination of a porous material and a board-shaped material is used. And

In the aspect in which the ceiling decorative material is composed of a plurality of materials in which the porous material and the board-shaped material are combined, the portion of the ceiling decorative material and the characteristics required by the ceiling decorative material are all burdened on either one. It can also be said that each material is assigned to each material instead of being assigned.
The decorative surface portion can be improved in strength by leaving it exclusively to the board-like material, and the fitting portion and the engaging portion may be left to the porous material. In other words, the board-shaped material is not particularly limited as long as it has the characteristics required for the decorative surface portion, and the porous material has the characteristics required for the fitting portion and the engaging portion. The material is not particularly limited as long as it has.

The decorative surface portion is a portion extending between the adjacent support members, and is formed into a substantially flat shape (a substantially horizontal shape) in a side view in the illustrated embodiment described later, but the shape is not particularly limited. Absent.
Further, the decorative surface portion is folded up or down at the rear end and the front end depending on the material to be used, the plate thickness or the length (the depth direction in the later-described drawing (for example, FIG. 1)), the width (the spacing between the support materials), and the like. It may be That is, in that case, the bending strength of the decorative surface portion is increased, the weight can be reduced, and the shape stability is also increased. In addition, a plurality of porous materials may be used as an aid for the decorative surface portion, the front end and the rear end in the length direction may be folded up, and the board-like material may be held between the folded pieces.

As described above, the fitting portion is a portion that extends downward from the left and right of the decorative surface portion and is disposed above (inside) the lower flange of the support member at least in the attached state, and the lower end thereof is An engaging portion is provided. This engaging portion is elastically engaged with the tip of the lower flange in the attached state.
For example, the behavior in the case where the ceiling decorative material is arranged so as to be pushed in from below will be briefly described. By pushing in from below, the left and right fitting portions are respectively pushed up while being in contact with the tips of the lower flanges of the support material. Therefore, the ceiling decorative material is pushed up while receiving the stress that is narrowed against the elasticity. Then, the stress is released when the lower end of the fitting portion that expands to the outermost side reaches above the lower flange of the support member (when the fitting portion is pushed in), and the engagement provided at the lower end of the fitting portion is released. The portion elastically engages with the tip of the lower flange to obtain a stable arrangement state.
The shape of this fitting portion may be formed in any manner and is not particularly limited. However, the engaging portion provided at the lower end of the adjacent supporting member is provided from the outside to the tip of the lower flange of the supporting member. Since they engage with each other, it is desirable that the lower end of the fitting portion be expanded to the outermost side.
Also, the shape of the engaging portion may be appropriately set depending on the configuration of the lower flange of the support member, but for a lower flange without a lip, it may be formed by folding back the front end of the horizontal piece along the lower flange. The lower flange having the lip may be formed in an L shape along the lower flange and the lip.

As described above, in order to stably attach the ceiling decorative material to the lower flange of the support material, it is desirable to elastically engage the ceiling decorative material.
It is needless to say that the width between the left and right fittings (= the maximum width of the ceiling decorative material) is made longer than the distance between the lower flanges of the adjacent butted supporting materials (= the length of the butted space). There is no (otherwise, the arranged ceiling decorative material will fall), but for example, if the expansion angle between the fitting part and the decorative surface part is formed to be wider than the angle of the mounted state, The elasticity also acts on the provided engaging portion, and even if the expanding angle between the fitting portion and the engaging portion is expanded to be larger than the angle in the mounted state, the elasticity is applied to the engaging portion. As such, it is desirable to employ either or both aspects to elastically engage.

  A fixing portion extending downward may be provided at the lower end of the engaging portion. That is, by fixing a fixing tool such as a screw from the fixing portion, the engagement portion can be fixed more firmly and reliably.

Further, it is desirable to provide a decorative cover that covers the lower flange of the support member from below as in the illustrated embodiment described later. In this case, the appearance of the entire ceiling can be improved in combination with the above-mentioned ceiling decorative material.
The decorative cover has a decorative surface that covers the lower flange of the support member from below, and is formed in an elongated shape that is continuous in the length direction of the support member. In addition, this decorative cover may be provided with a structure that assists (strengthens) the attachment of the support member and the ceiling decorative material.
