Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a ceiling structure in a high-rise building or the like.

(Prior art and its problems) Conventionally, in a ceiling structure in a high-rise building, a large number of hanging fittings called T-bars are hung from a ceiling base material fixed to a ceiling slab, and between adjacent hanging fittings. Drop the ceiling plate on the bottom and erect the lower surface of both ends of the ceiling plate on the lower horizontal projection of the hanging bracket.
A so-called system ceiling structure that is mounted is adopted.

In such a ceiling structure, when refurbishing the ceiling surface, it is necessary to remove the existing ceiling board and then replace it with a new ceiling board, or even if the ceiling board is partially soiled,
Since it is required to unify the design and material of the decorative surface, there is an inconvenience such that the entire surface must be repaired.

For this reason, it has been proposed that the same decorative layer be provided on the upper surface side of the ceiling board so that the ceiling board can be turned over to expose the decorative surface at the time of repair. The decorative surface on the upper surface is also soiled due to dust adhesion and is difficult to use.

In order to eliminate such defects, it is possible to attach an antifouling sheet on the unused upper surface in advance.However, when the sheet is attached, it is necessary to reverse the use. When the sheet is peeled off, the adhesive remains on the decorative surface, or the decorative layer is partially peeled off together with the sheet to impair makeup, and when the sheet is attached to the entire decorative surface, the ceiling plate warps. There was a problem such as fear.

It is an object of the present invention to provide a ceiling structure that solves the above problems of the present invention.

(Means for Solving Problems) In order to achieve the above object, the ceiling structure of the present invention has a decorative layer (2) on the upper and lower surfaces of a ceiling plate (1) as shown in the drawings corresponding to the embodiments. (3) is provided, the decorative layer (2) on the upper surface side is covered with a sheet material (4), and the peripheral edge of the sheet material (4) is a ceiling plate.
Removably fixed to the peripheral end of (1), the lower end surface of the outer peripheral portion of the ceiling plate (1) is vertically adjacent to the ceiling base material (6) at predetermined intervals in the adjacent hanging metal fittings ( 7) It is characterized in that it is erected and mounted on the lower horizontal projection strips (8) and (8) of (7).

(Function) Since the decorative layers (2) and (3) are provided on the upper and lower surfaces of the ceiling plate (1), both sides can be used, and the lower decorative layer (3) that does not cover the sheet material (4) can be used. If you are constructing a ceiling surface,
The top decorative layer (2) is a sheet material covering the decorative layer (2)
The sheet material is prevented from being soiled by (4) and
Since only the outer peripheral end of (4) is fixed to the peripheral end of the ceiling plate (1), there is no fear that the ceiling plate (1) will be warped.

Next, when the ceiling surface is to be refurbished after long-term use, the sheet material (4) can be easily removed by removing only the outer peripheral end portion of the sheet material (4) from the peripheral end surface of the ceiling board (1). The decorative layer (2) from which the sheet material (4) has been removed can be used as the ceiling surface. At this time, sheet material
The peeling portion of (4) is the peripheral end surface of the ceiling plate (1), and since the portion is hidden by the hanging metal fittings (7) and (7), the decorative layer (3) is not damaged.

(Embodiment) Explaining an embodiment of the present invention with reference to the drawings, (1) is a ceiling board made of rock wool, glass wool fiber board, decorative gypsum board or other appropriate material, and a decorative layer (2) on both upper and lower surfaces thereof.
(3) is provided.

The decorative layers (2) and (3) may be applied by painting, or may be formed by an appropriate means such as printing, cutting, and transcription.

(4) is a sheet material that covers the decorative layer (2) on the upper surface side, and is made of a synthetic resin sheet such as polyethylene or polypropylene or paper, and only the outer peripheral end of the sheet is attached to the peripheral end of the ceiling board (1). It is fixed.

As shown in FIG. 1, this fixed portion may be the outer peripheral edge of the upper surface of the ceiling plate (1), or, as shown in FIG. 2, the outer peripheral edge of the sheet material (4) may be the ceiling plate. The bent portion may be fixed by bending the outer peripheral end face of (1).

Further, as shown in FIG. 3, a means for bending the outer peripheral end of the sheet material (4) from the end face of the ceiling plate (1) to the rear end and fixing it at the end, as shown in FIG. In addition, a locking step (5) is formed on the outer peripheral edge of the ceiling plate (1), and a means for fixing the outer peripheral end of the sheet material (4) to the upper surface of the locking step (5) is provided. It may be adopted, but in short, if it is fixed to the part hidden by the lower horizontal projection strip (8) of the hanging metal fitting (7) described later so that it is not exposed to the indoor side during reversing use. It's good.

As the fixing means, an adhesive or an adhesive (9) is applied to the outer peripheral edge of the sheet material (4) in a dotted or linear manner along the edge, and the adhesive or the adhesive (9) is used. It may be releasably fixed to the outer peripheral edge of the ceiling plate (1), or may be fixed by a tucker needle (10) as shown in FIG.

The ceiling plate (1) configured in this manner, the hanging metal fittings (7) (7), which are hung vertically on the lower surface of the ceiling base material (6) at predetermined intervals.
・ In, the lower surface of both ends of the hanging metal fittings (7) and (7) is dropped into the space between the adjacent hanging metal fittings (7) and (7).
(8) It is installed while being placed on (8).

A T-shaped bar is used as the hanging metal fitting (7), but an L-shaped bar is used at the ceiling end.

Now, as shown in the figure, when the ceiling plate (1) is stretched with the lower surface decorative layer (3) facing the indoor side, the upper surface decorative layer
The sheet (2) is covered with the sheet (4) and is prevented from being damaged due to the adhesion of dust or the like.
