Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a binder that is free of fibers such as asbestos, rock wool, and glass materials, and free of binders such as gypsum, lucium silicate, and cement. Eleven methods for forming a non-combustible, sound-absorbing decorative ceiling surface by adhering and fixing an inorganic ceiling board formed by adding organic auxiliaries such as starch and phenolic resin to a curved ceiling base surface, and the construction method This relates to an inorganic ceiling board with a flexibility of (J'J).

Non-combustible, sound-absorbing inorganic-containing Jt boards are usually provided on the market as rock wool boards, gypsum boards, and slay boards, but they are usually about 9 to 25 sffl thick and have low flexibility. Cracking occurred due to inflection with a radius of curvature of 25 OCR+ or less, and it could not be put to practical use.

On the other hand, in order to match the WA sieving properties of indoor ceiling surfaces, it has become necessary to form a concave curved surface or an 11-sided curved surface with a radius of curvature of up to about 30 CIIl, but the conventional construction method for inorganic ceiling panels This was not applicable, and it became necessary to develop an improved method for this purpose.

As a result of repeated research and tests, the inventors have found that
A construction method capable of imparting sufficient curvature to conventional inorganic ceiling panels, compensating for the decrease in strength, and forming a decorative curved ceiling with inorganic ceiling panels, and its implementation]
One person has invented an inorganic ceiling panel for use in one method.

That is, the present invention (with a radius of curvature of approximately 300C1ll or less)
It is applied when bonding and fixing an inorganic ceiling board to a ceiling base having a curved surface of 0CII1 or more.

Normally, inorganic ceiling panels used to create decorative ceiling surfaces either have a flat base pattern or a continuous uneven pattern on the surface.

A certain repeating pattern is formed to create a three-dimensional decorative surface, and the back side is attached to the ceiling base with adhesive, and nailing is also used at this time to maintain the condition until the adhesive assimilates. When the ceiling base is a curved surface, the internal stress caused by the deformation of the ceiling board concentrates on the nailing area, causing cracks in the core or requiring extra nailing. If it is less than 251, there is a risk that the inorganic ceiling board itself will crack and break, and there was no way to deal with this problem other than making the board narrower and attaching it to a normal flat board product, or manufacturing a special curved product. .

In order to improve this point, the present invention has a plurality of grooves recessed in the normal direction of the curved surface of the substrate on the back or front surface of an ordinary inorganic ceiling board, and a coarse cloth is completely pasted on the back surface. By reinforcing the inorganic ceiling board or pasting a reinforcing thin paper tape in the direction perpendicular to the cut groove, it gives the inorganic ceiling board the desired flexibility, prevents a decrease in strength, and improves the radius of curvature. There is a design that allows the large sealing plate to be easily attached and fixed to a small curved ceiling base material. Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a plan view of the back side of the first parfocal rice bowl plate 1, and FIG. It has a striped pattern surface with parallel protrusions 6 formed thereon. Then, from the back side, groove 5
Leave a connecting part 7 of 1 to 21 mm in the middle part 1 to 1
, 5111 cut ig3 is recessed with an appropriate gap,
Two pieces of paper tape 4 are exposed on the back side 2 and are perpendicular to the group of instep grooves.
．． 4 is attached.

As the paper tape 4, it is preferable to use kraft paper with fine wrinkles, elongation, and high paper strength, but other film-like tapes may be used instead.

Alternatively, coarse cloth such as cheesecloth may be applied over the entire surface.

The cross-sectional shape of the front cut groove 3 corresponds to the strength of the inorganic ceiling board.

The width and depth are determined depending on the flexibility and the radius of curvature of the curved surface of the base material, and the spacing between them is also determined accordingly.

FIG. 3 is a cross-sectional view of the main part of the concave ceiling installation part A, in which a curved surface base 11 with a radius of curvature R formed by pasting plasterboard on the ceiling frame 10 is fixed with nails 12.
On the surface of the inorganic large lunar plate 1, adhesive coating parts of small areas are provided and crimped, distributed on the back surface, and bent at the connection part 7 of the kerf 3, and the upper part of the kerf 3 is expanded to form a substantially base material. 110 curved along the curved surface, nails 17 are driven into the four stripes 5 of the pattern to form the same tube, and in the same way, other ceiling panels 17.1r' are installed above and below with joints 15.16, In addition, other ceiling panels are connected in the longitudinal direction to form a decorative concave ceiling, and the adhesive that is present in the slight gap formed between the back surface 2 of the ceiling panel 2 and the base 11 is solidified. This allows it to be stably fixed.

Figure 4 is a sectional view of the main part of the convex curved Otsuki construction part.
The upper part of M3 is sandwiched to form a gap 14' between the core and the surface of the substrate 11, and the contact surfaces with other vertically adjacent tendon plates 1' and 1'' are boxed. The embodiment is exactly the same as the embodiment shown in FIG. 3, except that it is slightly chamfered.

5 and 6 show a ceiling board for a concave curved surface in still another embodiment, and FIG. 5 is a back view thereof.

FIG. 6 is an enlarged cross-sectional view taken along line B--B in FIG.

The inorganic ceiling board 1 has two reinforcing tapes 4゜4 pasted on the back side in the longitudinal direction, and the front side has grooves 5' and convex lines 6' in the longitudinal direction.
The stripes are alternately parallel to each other, and horizontal kerfs 3' are 1 to 2 mm in length from the surface in the direction orthogonal to the stripe patterns.
The incision angle of the cut grooves 3' is determined by the radius of curvature of the concave curved surface and the interval between the cut grooves 3'. A method of setting the incision angle to 6 degrees and adjusting the mutual spacing of the cut grooves 3' in accordance with fluctuations in the radius of curvature R of the concave curved surface was effective in T industry.

FIG. 7 is a cross-sectional view of the main part when the above-mentioned ceiling board is used to cover 11 surfaces of the C-shaped concave ceiling base. This means that the appearance will not be damaged. Other fixing means are the same as in Moejo's case.

As explained above, according to the present invention, inorganic ceiling panels can not only be stably and securely adhered to concave or convex ceiling substrates, but also avoid any adverse effects on the surface irregularities of the ceiling panels. No: ・1 So, should we mold a special curved board as in the past, or use a large number of narrow 1] boards to construct a curved surface? l! This provides an industrial effect in which a curved ceiling decorative surface can be easily applied without requiring complicated preparations or multiple steps.
