[Action]

By constructing as described above, several hanging metal fittings are engaged with the first and second field edges attached to the back surface of the ceiling plate material, and these hanging metal fittings are fixed to the field edge receivers provided on the ceiling. By doing so, it is possible to provide an inexpensive suspended ceiling device in which a suspended ceiling can be easily formed and constructed, and in which the ceiling plate material does not bend or warp.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a state in which first and second rims and a reinforcing frame are attached to the back surface of the ceiling plate material of the suspended ceiling device according to the present invention, and FIG. 2 is a short side of the ceiling plate material. A front view seen from the side, FIG. 3 is an explanatory view showing the structure of a hanging fitting used in the present invention, and FIG. 4 is an explanation showing a state in which a ceiling plate material is hung using the hanging fitting shown in FIG. 5 and 5 are explanatory views showing the state of the engaging portion.

In the drawings from FIG. 1 to FIG. 5, 1 is a first field edge, 1a is a bottom plate portion, 1b and 1b are side plate portions, 1c and 1c are a pair of reinforcing hooks forming a locking portion, and 1d is Reinforcing ribs, 2 is a second edge, 2a is a mounting portion, 2b is a joint forming portion, 2c is a locking portion, 2d is a reinforcing rib, 3 is a reinforcing frame, 4 is a ceiling plate member, 5
Is a hanging metal fitting, 5a is a locking portion, 5b is a locking hook, and 6 is a field frame receiver provided on the ceiling.

Thus, the ceiling board 4 is made of a gypsum board, or a flame-retardant material or a non-combustible material similar to this, and the first field edge 1 is attached along one longitudinal edge of the board. To be The first field edge 1 has a substantially uniform cross section perpendicular to the axis over the entire length, and is fixed to the bottom plate portion 1a in contact with the back surface of the ceiling plate member 4 and both sides in the longitudinal direction of the bottom plate portion 1a. A pair of side plate portions 1b, 1b standing upright opposite to each other, and a pair of reinforcing hooks 1 protruding inward from the tops of the pair of side plate portions 1b, 1b and facing each other at regular intervals.
c and 1c are formed, and if necessary, a reinforcing rib 1d is formed in the center of the bottom plate portion 1a along the longitudinal direction.

Further, the ceiling plate member 4 to which the first field edge 1 is attached
The second field edge 2 is attached to the opposite side of the.
The second field edge 2 has a substantially uniform cross section perpendicular to the axis over the entire length, and is fixed to the mounting portion 2a in contact with the back surface of the ceiling plate member 4 and the mounting portion 2a and the same plane as this. A flat plate-like joint forming portion 2b that extends so as to project from the end side of the ceiling plate member 4 and a single locking member that stands up from the surface of the joint forming portion 2b opposite to the surface facing the ceiling plate member 4 The portion 2c is formed, and if necessary, the reinforcing rib 2d is formed along the longitudinal edge on the side opposite to the locking portion 2c.

Furthermore, a plurality of reinforcing frames 3 are provided between the first field edge 1 and the second field edge 2 on the back surface of the ceiling plate material 4, if necessary.
3 are suspended and combined. This prevents the ceiling plate member 4 from being bent or warped during inventory or transportation.

The hanging metal fitting 5 is made of a thin metal plate, and has an inverted T-shaped locking portion 5a that engages with the pair of reinforcing hooks 1c, 1c of the first field edge 1 at one end thereof and the second field edge 2 A locking hook 5b that engages with the locking portion 2c is formed.

Thus, when constructing a suspended ceiling using the suspended ceiling device according to the present invention configured as described above, first, the first field edge 1 attached to the first sheet of ceiling plate 4 is mounted. The reinforcing hooks 1c, 1c are engaged with the engaging portions 5a, 5a of at least two suspending metal fittings 5, 5 to attach them at a constant interval. Then, similarly to the locking portion 2c of the second field edge 2 attached to the opposite side edge of the same ceiling plate material 4, at least two or more hanging metal fittings 5, 5 locking hooks 5b, 5b. And fit them at regular intervals. After that, the plurality of hanging metal fittings 5, 5 attached to the first field edge 1 and the second field edge 2 are fixed to the field edge receiver 6 provided on the ceiling. As a result, the first sheet of ceiling plate material 4 is suspended from the ceiling.

Next, on the side where the locking portions 5a, 5a of the hanging metal fittings 5, 5 fixed to the field edge receiver 6 are projected as they are unused, another first edge of the ceiling plate material 4 is added. 1 is to be locked, but in that case, some new hooks 5 of the hanging metal fittings 5, 5 are previously attached to the locking portion of the second field edge of the new ceiling plate material.
Before fitting the b and 5b together, the first hanging edge 1 of this ceiling board is already fixed to the hanging edge 6 in order to suspend the previous ceiling board. 5, 5 locking parts 5a, 5a
And the new suspension fittings 5, 5 attached to the second field edge of the new ceiling plate material are fixed to another field edge receiver 6.

On the other hand, on the side of the hanging metal fittings 5 and 5 which are first fixed to the field rim receiver 6, the locking hooks 5b and 5b are projected unused.
Further, the second field edge 2 of another new ceiling plate material 4 is locked, but in that case, a pair of reinforcing hooks of the first field edge of the new ceiling plate material is previously provided with some Before the hooks 5a, 5a of the new hanging metal fittings 5, 5 have been fitted, and the second field edge of the new ceiling plate material is already fixed to the field edge receiver 6. The hooks 5b and 5b of the hanging metal fittings 5 and 5 are engaged, and the new hanging metal fittings 5 and 5 attached to the first field edge of the new ceiling plate material are further fixed to the field edge receiver 6. is there.

By repeating the same procedure below, a large number of ceiling plate materials are suspended in order and the entire ceiling is stretched.

As described above, a beautiful suspended hanging ceiling can be stretched by simply stretching the ceiling plate member 4 from one side in order, so that the ceiling stretching work can be performed very efficiently. be able to.

Since the ceiling plate member 4 is formed of gypsum board or the like, it absorbs moisture, and the ceiling plate member 4 may hang down when it is used for a long time. Therefore, when the ceiling of a humid room is stretched, if a plurality of reinforcing frames 3 and 3 provided on the back surface of the ceiling plate member 4 and the ceiling plate member 4 are fixed with an adhesive or the like, the ceiling It is possible to completely prevent the plate member 4 from hanging down.

[Advantage of the Invention] Since the present invention is configured as described above, according to the present invention, the hanging metal fittings are engaged with the first and second field edges attached to the back surface of the ceiling plate material, and the hanging metal fittings are engaged. Since it is possible to easily form a suspended ceiling simply by fixing the to the field rim receiver, and because the ceiling plate material is less likely to bend, warp, etc.,
A beautiful suspended ceiling can be stretched in a short time.

The present invention is not limited to the above embodiment,
The shape of the first and second field edges and the shape of the hanging metal fittings that are attached parallel to both longitudinal end surfaces of the ceiling plate material may be other shapes as long as the same effect can be achieved. Of course, well-known non-combustible materials can be used as the material of the ceiling plate material, and therefore, the present invention covers all modified embodiments that can be easily conceived by those skilled in the art from the above description. is there.
