Description

[Detailed description of the invention] The present invention relates to a ceiling board, which constitutes the ceiling of a melting room, etc., and has a double wall structure to provide heat insulation effect, and to To prevent sink marks from occurring on the inner wall due to ribs provided for reinforcement between the walls, and to suppress warping of the inner wall due to the difference in expansion and contraction between the inner wall and the outer wall. With the goal.

The present invention will be explained below based on drawings showing an example of implementation. In the figure, 1 has an inner wall 2 located on the indoor side and an outer wall 3 located above the inner wall 2, forming a cavity 4 between the inner and outer walls 2 and 3, and male mold parts on both left and right sides. 5 and a female part 6 are formed over the entire length in the longitudinal direction, and the whole is integrally formed of synthetic resin. The male part 5 on one side of the ceiling board 1 consists of one board 7,
The female part 6 on the other side of the ceiling board 1 is made up of two board parts 8 and 9, and when the two ceiling boards 1 and 1 are placed next to each other as shown in FIG. Board 1
The male part 5 of the ceiling plate 1 can be fitted into the female part 6 of the other ceiling plate 1. The upper plate part 8 of the female mold part 6 is formed wider than the lower plate part 9, and is nailed to a ceiling beam 10 or the like with a nail 11. 12 is a locking protrusion formed on the lower surface of the male mold part 5 over the entire length of the ceiling plate 1; 13 is a locking protrusion formed on the upper surface of the lower plate part 9 of the female mold part 6 of the ceiling plate 1. This is a locking groove portion formed over the entire length in the length direction. A plurality of locking groove portions 13 are formed, and any one locking groove portion 13 is connected to the male part of the adjacent ceiling plate 1. 5
The locking protrusion 12 can be locked.
14 are provided projecting along the length direction of the ceiling plate 1 at appropriate intervals in the width direction of the ceiling plate 1 on the inner surface of the outer wall 3 in the cavity 4 in order to reinforce the inner and outer walls 2 and 3. The lower end of the rib 14 is only in contact with the inner wall 2 and is not fixedly connected thereto.
The plate part 7 of the male part 5 is located slightly above the outer wall 3, and the lower surface of the upper plate part 8 of the female part 6 is at the same height as the upper surface of the plate part 7 of the male part 5. It is formed to be.

Therefore, when forming a ceiling using a large number of ceiling panels 1, the upper panel section 8 of the female section 6 is attached to the male section 6 of the ceiling panel 1, which is nailed to a beam 10 of the ceiling with nails 11. The male part 5 of another ceiling board 1 is fitted and its locking protrusion 12 is locked in the locking groove part 13 of the female part 6 of the previously nailed ceiling board 1.
The upper plate part 8 of the female mold part 6 is nailed to a ceiling beam 10 or the like with a nail 11. In this manner, a large number of ceiling panels 1 are sequentially nailed together to form a ceiling.

The ceiling panel of the present invention can be implemented as described above, and since it has a double wall structure consisting of an inner wall and an outer wall, it has a heat insulation effect, and is especially effective when forming the ceiling of a solution room. demonstrate. Also, ribs are provided to reinforce the interior and exterior walls.
Since the lower end of this rib is separated from the inner wall, there is no sinkage on the inner wall, and the difference in expansion and contraction between the inner and outer walls (expansion and contraction is large in the case of a melting chamber) can suppress warpage and improve beauty.
