<< construction method of ceiling 1 >>
Next, the construction method of the ceiling 1 comprised as mentioned above is demonstrated, referring FIGS. 9-14. FIG. 9 is a diagram showing a procedure of work for constructing the ceiling 1 (hereinafter, ceiling construction work). FIG. 10 is a view showing how the ceiling panel 2 is lifted upward. FIG. 11 is a view showing a state in which the field edge side projecting portion 8 collides with the lower side corner portion of the field edge receiver 3 when the ceiling panel 2 is lifted upward. FIG. 12 is a view showing the manner in which the ceiling panel 2 is horizontally moved with respect to the border rim 3. FIG. 13 is an explanatory view of the movement of the edge side protrusion 8 when the ceiling panel 2 is moved horizontally. FIG. 14 is a view showing how the outer edge portion of the board material 5 is screwed to the flange 3.

  Below, in demonstrating the construction method of the ceiling 1 of this invention, suppose that the procedure of the ceiling construction work which concerns on this embodiment is demonstrated. In the ceiling installation work which concerns on this embodiment, each step (process) shown in FIG. 9 is implemented in order. Specifically, in the ceiling installation work, first, the ceiling panel 2 configured by attaching the edge 6 to the upper surface of the board material 5 is lifted so as to approach the plurality of edge edges 3 arranged above it. It starts from the place (S001).

If it explains in more detail, frame work will be performed in the front step of ceiling construction work, and field edge receptacle 3 and cross member 4 will be arranged in the shape of a well in the frame work concerned. That is, a plurality of field edge receptacles 3 are arranged along the inter-beam direction at regular intervals, and horizontal members 4 are disposed between the field edge receptacles 3 at regular intervals in the row direction. Thereafter, ceiling installation work is started, and the ceiling panel 2 is lifted vertically upward by the lifter L illustrated in FIG. At this time, the ceiling panel 2 is lifted after adjusting the position of the ceiling panel 2 so that the ceiling panel 2 is positioned between two field edges 3 adjacent to each other in the inter-beam direction (that is, the space V).
In the present embodiment, the ceiling panel 2 is lifted using the lifter L. However, the present invention is not limited to this, and the ceiling panel 2 may be lifted manually.

  When the ceiling panel 2 is lifted, the edge 6 of the ceiling panel 2 eventually enters the space V between the edge receivers 3. At this time, if the position of the ceiling panel 2 is slightly shifted in the inter-beam direction, as shown in FIG. 11, the end in the extension direction of the edge 6, ie, the upper surface 8a of the edge side protrusion 8 It comes in contact with the lower corner. Here, as described above, the upper surface 8 a of the field edge side projecting portion 8 is inclined so as to be lowered toward the outer side in the extension direction of the field edge 6. Thereby, when the ceiling panel 2 is lifted in a state where the upper surface 8a of the field edge side projecting portion 8 abuts on the lower side corner portion of the field edge receiver 3, the ceiling panel 2 becomes the field edge side projecting portion 8 as shown in FIG. It moves obliquely upward while being guided by the upper surface 8a. As a result, the ceiling panel 2 is guided to a position where the edge 6 enters the space V between the edge receivers 3 in the inter-beam direction.

  When the ceiling panel 2 is further lifted, the upper surface of the board material 5 comes in contact with the lower surface of each of the edge support 3 and the horizontal member 4. The position of the ceiling panel 2 at this point is such that the edge 6 is slightly away from the protrusion 7 in the row direction.

  Then, the ceiling panel 2 is lifted to a position where the border 6 enters the space V between the border supports 3 and the upper surface of the board material 5 abuts on the lower surface of each of the border support 3 and the horizontal bridge 4. Thereafter, as shown in FIG. 12, the ceiling panel 2 is horizontally moved along the column direction (S002). More specifically, the ceiling panel 2 is moved so that the edge 6 moves toward the protrusion 7 (strictly speaking, the nearest protrusion 7) which protrudes inward of the space V from the side end face of the edge receiver 3 Move horizontally Then, finally, the ceiling panel 2 reaches a position where the extension direction end of the edge 6, that is, the edge side protrusion 8 is placed on each protrusion 7 (S003). That is, in steps S002 and S003, the ceiling panel 2 is horizontally moved so that the field edge side projecting portion 8 is placed on each projecting portion 7.

  In the present embodiment, as described above, the upper surface 7a of the protrusion 7 is an inclined surface. Then, with the horizontal movement of the ceiling panel 2, as shown in FIGS. 12 and 13, the field edge side protruding portion 8 is the lower end (hereinafter, the lower end of the inclined surface) of the upper surface 7 a which is the inclined surface. It moves in the direction of arrow, that is, in the direction of the arrow in the figure.

The horizontal movement of the ceiling panel 2 causes the field edge side projecting portion 8 to pass through the position immediately above the lower end of the inclined surface and finally to be placed on the upper surface 7a. Further, in the present embodiment, the lower surface 8b of the field edge side protruding portion 8 is also an inclined surface. Thereby, while the field edge side projection part 8 passes the position directly above the projection part 7, the distance between the lower surface 8b of the field edge side projection part 8 and the upper surface 7a of the projection part 7 becomes small gradually, and the field edge side projection part When 8 is placed on the protrusion 7, the lower surface 8b of the non-edge protrusion 8 comes in surface contact with the upper surface 7a along the upper surface 7a of the protrusion 7 as shown in FIG. In other words, due to the horizontal movement of the ceiling panel 2, the protrusion 7 enters the gap between the non-edge side protrusion 8 and the board 5. Thus, the protrusion 7 functions as a weir, and after the field edge side protrusion 8 is placed on the protrusion 7, it is possible to stably maintain the state.
Even if an error between the actual dimension and the design dimension occurs in the projecting portion 7 or the field edge side projecting portion 8, both the upper surface 7a of the projecting portion 7 and the lower surface 8b of the field edge side projecting portion 8 become inclined surfaces. It is possible to absorb the above-mentioned error.

By the steps described above, each field edge 6 enters the space V between the field edge receivers 3 and the field edge side protrusion 8 of each field edge 6 comes to rest on the protrusion 7. In this state, the side edge portion of the outer edge portion of the board material 5 is located directly below each of the pair of non-edge supports 3 sandwiching the space V, and the front and rear edge portions of the outer edge portion of the board material 5 Is located immediately below the horizontal bridge 4 connecting the pair of field edge receivers 3 to each other. That is, each outer edge 6 enters the space V between the outer edge receivers 3 and the outer edge side projecting portion 8 of each outer edge 6 is placed on the projecting portion 7 so that the outer edge portion of the board 5 is edged. It comes to the position where it is fastened to the receptacle 3 and the cross member 4.
In addition, the ceiling panel 2 is temporarily placed at the above position. That is, even when the ceiling panel 2 is removed from the lifter L, the ceiling panel 2 can be held at the above position without falling because the field edge side projection 8 is placed on the projection 7.

The above-described series of steps (ie, S001 to S003) are repeated until all the ceiling panels 2 constituting the ceiling 1 are laid (spreaded). Thereafter, using a screw driver J shown in FIG. 14, a screw B is driven into each portion of the outer edge portion of the board material 5 from below the board material 5 of each ceiling panel 2 laid (S004). As a result, the outer edge of the board material 5 of each ceiling panel 2 is screwed (fastened) to the edge support 3 or the horizontal mounting member 4. As a result, each ceiling panel 2 is supported by the edge support 3 and the cross member 4.
The ceiling construction work is finished when the above steps are finished.

  As described above, in the ceiling installation work of the present embodiment, the outer edge portion of the board material 5 is screwed to the field edge receiver 3 in order to support the ceiling panel 2 on each of the plurality of field edge receivers 3. Do. At this time, the ceiling panel 2 is lifted so that the field edge 6 enters the space V between the field edge receivers 3, and the ceiling panel 2 is moved horizontally so that the field edge side protrusion 8 rests on the protrusion 7. As a result, the outer edge portion of the board material 5 comes to a position where it is fastened to the edge support 3 or the horizontal mounting member 4. That is, in the ceiling installation work of the present embodiment, the outer edge portion of the board material 5 is appropriately guided to a position where it is fastened to the edge support 3 or the horizontal support 4 by lifting and horizontal movement of the ceiling panel 2 described above. As a result, the ceiling panel 2 can be properly supported by the edge support 3 and the cross member 4.
