[0002]

2. Description of the Related Art Conventionally, a transparent ceiling plate having a structure shown in FIG. The see-through ceiling plate 72 shown in FIG. 4 has a long rectangular ceiling plate body 74 whose lower surface is subjected to decorative processing, and a pair of horizontal joint grooves 76 formed in the middle of the outer surface along the length direction. It comprises prismatic vertical bars 78, 78 and a plurality of prismatic horizontal bars 80, while fixing the lower surfaces of both vertical bars 78, 78 to both ends in the width direction of the upper surface of the ceiling plate main body 74. A plurality of prismatic horizontal rails 80 are fixed between 78.

FIG. 5 is a perspective view of a transparent ceiling constructed using a transparent ceiling plate 72. The construction of the transparent ceiling shown in FIG. 5 is usually performed by the procedure described below. By placing both ends in the length direction and one end in the width direction of the ceiling plate starting to be stretched on the peripheral edge fixed to the upper end of the wall of the room, the ceiling plate is arranged on the peripheral edge. The vertical bar 78 existing at the other end in the width direction of the ceiling plate at the beginning of the tensioning is fixed to a base material 82 such as a field edge or a plate material by nailing. One end of the joint plate 84 in the width direction is inserted into the joint groove of the ceiling plate at the beginning of tensioning, and the other end of the joint plate 84 in the width direction is connected to the joint of the vertical bar 78 at one end in the width direction of the second ceiling plate. Insert into the trench. Thereafter, in the same manner as described above, the vertical rail 7 existing at the other end in the width direction of the second ceiling plate is formed.
8 is fixed to the base material 82 by nailing. From the third sheet to the ceiling panel just before the tension ceiling panel, the above operation is repeated and fixed to the base material 82. The ceiling plate of the upholstery is placed with its both ends in the length direction and the other end in the width direction placed on the peripheral edge.

[0004]

However, the conventional transparent ceiling panels have been unsatisfactory in the following points. First, in order to fix the vertical and horizontal rails having different arrangement directions on the upper surface of the ceiling panel body during manufacturing so that the ceiling panel retains sufficient rigidity, the vertical rail is fixed to the ceiling panel body during the manufacturing process. And a line for fixing the crosspiece are required, which complicates the manufacturing process. Secondly, since the construction is performed using the joint plate, the ceiling construction is relatively troublesome. Third, since the lower surface of the ceiling panel body is a flat surface, even if various decorative processes are performed on the lower surface, there is a limit in the design properties that can be obtained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a ceiling panel capable of simplifying the manufacturing process and ceiling construction of the ceiling panel and obtaining a new design. The purpose is to:

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a rectangular ceiling plate main body, a length substantially equal to the length of the ceiling panel main body, and extends along the longitudinal direction of the ceiling panel main body. A plurality of ribs fixed to the lower surface of the ceiling plate body, and a plurality of square or rectangular prismatic ribs having a cross section arranged in parallel with being equidistantly separated from each other, and one end side in the width direction of the ceiling plate A part of the ribs existing in the ceiling plate protrudes outward from the side edge of the ceiling panel body, and the rib existing on the other end side in the width direction of the ceiling panel is located inside the side edge of the ceiling panel body, and , Rib width is 1-4cm, rib height is
0.5 to 3 cm, separation distance L1 of a plurality of ribs is ₁ to 4c
m, the distance L ₁ , the length L _{2 of the} rib present at one end in the width direction of the ceiling plate from the side edge of the ceiling plate main body, and the rib present at the other end in the width direction of the ceiling plate. The distance L _{3 from} the side edge of the ceiling plate body is in a relationship of L ₃ −L ₂ = L ₁ .
Ri, further the protruding length L ₂ is rib width at least 0.7cm
4/5 is within the range, the distance L ₃ is 0.7c
The ceiling plate is characterized by being in the range of not less than m and not more than 4 times the rib width .

In manufacturing the ceiling panel of the present invention, a plurality of ribs need only be fixed to the ceiling panel body in the vertical direction at the time of manufacturing, and the plurality of ribs can be fixed to the ceiling panel body by one line. Can be simplified. When the ceiling is constructed using the ceiling plate of the present invention, as described later, the widthwise end of the ceiling plate is inserted into the gap between the protruding rib and the base material to support the ceiling plate body. Fixing to the base material by nailing or the like is performed sequentially. Therefore, according to the ceiling plate of the present invention, since the ceiling can be constructed without using the joint plate, the ceiling construction can be simplified. Further, since the lower surface of the ceiling plate has irregularities due to the ribs, the lower surface of the ceiling plate becomes three-dimensional, and as a result, a new design property can be obtained. In this case, in the ceiling panel according to the present invention, a plurality of ribs are fixed to the ceiling panel body only in the vertical direction, but the ceiling panel body is attached to the ground surface at predetermined intervals along the length direction at the time of ceiling construction. Is nailed,
Even without ribs along the width direction, the ceiling plate of the present invention maintains sufficient rigidity.

Further, in the ceiling plate of the present invention, since the plurality of ribs are equally spaced apart from each other, the manufacturing process can be simplified and the design can be more effectively improved. Still referring to FIG. 1, the distance L ₁ of the plurality of ribs, the projection length L ₂ from the side edge of the ceiling plate body rib existing on one widthwise side of the ceiling plate, the width direction other ceiling panel and the distance L ₃ between the side edges of the rib and the ceiling plate body existing on the end side, because a relation of L ₃ -L ₂ = L _1, effects described in the embodiment examples described below, can be obtained.

Hereinafter, the present invention will be described in more detail. In the present invention, examples of the material of the ceiling plate main body include plywood. Note that the width and length of the ceiling panel body may be appropriately determined according to the purpose, purpose, and the like of the ceiling panel. Examples of the material of the rib include a muku board, a glued laminated wood, a plywood, a hard board, an MDF, and an insulation board. Wood, plywood,
It is a hard board.

There is no particular limitation on the shape of the rib. For example, the rib may have a prismatic shape such as a square, a rectangle, an inverted truncated cone, or an inverted triangle, or a rounded shape such as a semicircular or semielliptical cross section. However, a square or rectangular cross-section prismatic rib is suitable because it can be easily fixed to the ceiling plate and the manufacturing process can be simplified.

The width (maximum width) of the rib is preferably in the range of 1 to 4 cm, especially 1.5 to 3 cm. When the width of the rib is smaller than 1 cm, the strength of the rib is reduced and the rigidity of the ceiling plate may be insufficient, and when the width is larger than 4 cm, the weight of each rib increases and the ceiling plate becomes too heavy,
Ceiling construction may be difficult. The width of the rib is 1
When it is within the range of ４4 cm, excellent design properties can be obtained.

The height (maximum height) of the rib is 0.5 to 3c.
m, particularly preferably in the range of 0.8 to 2 cm. If the height of the rib is smaller than 0.5 cm, the strength of the rib may be reduced and the rigidity of the ceiling plate may be insufficient,
If it is larger than 3 cm, the weight of each rib becomes large and the ceiling plate becomes too heavy, which may make ceiling construction difficult. When the height of the rib is in the range of 0.5 to 3 cm, excellent design properties can be obtained.

The distance L1 between the plurality of ribs is ₁ to 4c.
m, preferably in the range of 1.5 to 3 cm. If L ₁ is smaller than ₁ cm, the weight of the entire ribs increases and the ceiling plate becomes too heavy, making ceiling construction difficult. If L ₁ is larger than 4 cm, the ribs become too small and the rigidity of the ceiling plate becomes insufficient. Sometimes.

It is preferable that the projecting length L ₂ of the rib existing at one end in the width direction of the ceiling plate from the side edge of the ceiling plate main body is within a range of 0.7 cm or more and 4/5 or less of the rib width. L
_{If 2} is smaller than 0.7 cm, the width of the gap between the protruding rib and the base material is short, and it may be difficult to insert the widthwise end of the ceiling panel body into the gap, and 4/4 of the rib width may be used. If it is 5 or more, it may be difficult to fix the projecting rib to the lower surface of the ceiling plate with a sufficient holding force. The most preferred value for L ₂ is, considering that support the adjacent ceiling board is 1/2 of the rib width.

It is preferable that the distance L ₃ between the rib existing at the other end in the width direction of the ceiling plate and the side edge of the ceiling plate main body is within a range of 0.7 cm or more and 4 times or less of the rib width. 0.7cm
In the following, the length inserted into the gap between the protruding rib and the base material is short, and if it is four times or more the rib width, it is not preferable in terms of rigidity and design of the ceiling plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be specifically described with reference to embodiments, but the present invention is not limited to the following embodiments. FIG. 1 is a front view showing a ceiling plate according to the present invention as a single unit.

The ceiling panel 2 includes a rectangular ceiling panel body 4,
It has a length substantially equal to the length of the ceiling plate main body 4, and is constituted by a plurality of rectangular cross-section rectangular ribs 6 fixed to the lower surface of the ceiling plate main body 4 along the length direction of the ceiling plate main body 4. You. The ribs 6 are arranged in parallel at equal intervals (L ₁ ) from each other, and the rib existing at one end in the width direction of the ceiling plate 2 is outwardly by a length (L ₂ ) from the side edge of the ceiling plate main body. There is a protruding rib 6A that protrudes partially. The rib 6B on the other end in the width direction of the ceiling plate is located inside the side edge of the ceiling plate main body 4 by a length (L ₃ ), and L ₁ , L ₂
And L _3, a relation of L ₃ -L ₂ = L _1. In addition, the lower surface 9 and the side surface 10 of the rib 6 exposed in the room and the ceiling plate body 2
The lower surface 11 between the ribs is subjected to decorative processing.

The size of the rib 6 is, for example, a width B of about 2c.
m, height h is about 1 cm, and examples of the values of L ₁ , L _2, and L ₃ are about 2 cm, about 1 cm, and about 3 cm, respectively.
cm (see FIG. 1).

In order to construct a ceiling using the ceiling plate 2 having such a configuration, the following procedure is usually performed. In addition,
2 and 3 are a front partial cross-sectional view and a perspective view, respectively, showing a process of constructing a ceiling using the ceiling plate 2.
In the same manner as in the related art, the ceiling plate 2a is arranged by placing the ends of the ceiling plate main body 4 at both ends in the length direction and the other end in the width direction on the peripheral edge at the beginning of tensioning. The ceiling plate 2a is fixed to the base material 82 by hitting the nail 12 from the lower surface of the ceiling plate 2a at the beginning of tensioning. The nail 12 strikes, for example, at a boundary 14 between the lower surface of the ceiling plate main body 4 and the rib 6A. The base material 82 is composed of, for example, a gypsum board 90 and a ridge 92 thereon. Projecting rib 6 of ceiling plate 2a at the beginning of tensioning
The other end of the second ceiling plate 2b in the width direction of the ceiling plate main body is inserted, for example, from the U direction (see FIGS. 2 and 3) into the gap between A and the base material 82. Is supported by the protruding rib 6A, and the ceiling plate 2b is fixed to the base material 82 in the same manner as described below. From the third sheet to the ceiling plate just before the tensioned ceiling plate, the above operation is repeated and fixed to the base material 82. The ceiling plate with the upholstery is arranged by placing both ends in the length direction and the other end in the width direction of the ceiling plate body on the peripheral edge.

The ceiling panel 2 used for such an operation is
Since the ribs need only be fixed in the vertical direction of the lower surface of the ceiling panel body 4 during the manufacturing, the number of lines can be reduced and the manufacturing process can be simplified. In addition, when the ceiling is constructed using the ceiling plate 2, a joint plate is not required, and the other end in the width direction of the ceiling plate can be supported by the protruding rib 6A of the front ceiling plate to attach the ceiling plate. Therefore, the ceiling construction can be simplified. Further, since the relationship of L ₃ −L ₂ = L ₁ is satisfied, when the ceiling is constructed, the interval (L ₃ −L ₂ ) between the protruding rib and the rib of the adjacent ceiling plate is adjacent to one ceiling plate. Since it is equal to the distance between the ribs (L ₁ ), there is no uncomfortable feeling. Further, since the lower surface of the ceiling plate 2 has irregularities due to the prismatic ribs 6, the lower surface of the ceiling plate 2 becomes three-dimensional, and a new design property can be obtained.
