It is preferable to carry out the engaging step (step S3) of matching (FIG. 6).
Hereinafter, each step will be described in detail with reference to the drawings, using a 4P size ceiling panel 6 (FIG. 2) as an example.

(Ceiling panel temporary receiving jig preparation process)
In the process of preparing the ceiling panel temporary receiving jig (FIG. 6, step S1), the ceiling panel temporary receiving jig 10 of FIGS. 3A to 3C is prepared. Specifically, two ceiling panel temporary receiving jigs 10 are prepared for each ceiling panel 6.

(Jig mounting process)
Next, in the jig mounting step (FIG. 6, step S2), the ceiling panel temporary receiving jig 10 is mounted near the end portion of the ceiling panel 6 in the longitudinal direction. Specifically, two ceiling panel temporary receiving jigs 10 are prepared for one ceiling panel 6, and the ceiling panel 6 is attached to the panel fixing member 30 of the ceiling panel temporary receiving jig 10.

At this time, the screw 6D is passed through and fixed to the engaged portion 32 of the panel fixing member 30. More specifically, after inserting the head portion and the shaft portion of the screw 6D into the insertion hole 32a of the engaged portion 32, the shaft portion of the screw 6D is received by the receiving groove 32b. In this state, by tightening the screw 6D, the ceiling panel 6 is attached to the panel fixing member 30. In the same procedure, the panel fixing member 30 is attached to the other screw 6D, and two ceiling panel temporary receiving jigs 10 are attached to both ends of the ceiling panel 6.

By repeating this procedure, the ceiling panel temporary receiving jig 10 is attached near the end portion of each ceiling panel 6 in the longitudinal direction. The ceiling panel temporary receiving jig preparation step (step S1) and the jig mounting step (step S2) can be performed at the construction site of the ceiling panel 6, but from the viewpoint of shortening the construction period, the ceiling panel 6 It is preferable to do this in advance at the manufacturing plant of.

Further, after the panel fixing member 30 is attached to the ceiling panel 6, the wire W or the skeleton engaging member 20 may be attached to the ceiling panel 6 and temporarily fixed by using a curing tape or the like. By doing so, the ceiling panel temporary receiving jig 10 does not get in the way, and the entanglement of the wire W and the skeleton engaging member 20 between the different ceiling panels 6 is suppressed. Therefore, since it is possible to stack and mount a plurality of ceiling panels 6, space saving at the work site, efficiency at the time of transportation, and efficiency of work when the ceiling panels 6 are taken one by one are realized. To.

Further, in the ceiling panel suspension step described later, when the ceiling panel 6 is suspended from the beam 2 so as to be substantially horizontal, it is necessary to attach the ceiling panel temporary receiving jigs 10 to the four corners of the ceiling panel 6. However, in the present embodiment, since the ceiling panel 6 is suspended from the beam 2 so as to be substantially vertical, it is sufficient to use two ceiling panel temporary receiving jigs 10 for one ceiling panel 6. Therefore, the number of ceiling panel temporary receiving jigs 10 to be used can be saved.

(Engagement process)
Next, in the engagement step (FIG. 6, step S3), the two ceiling panel temporary receiving jigs 10 attached to the ceiling panel 6 are engaged with the beam 2. Specifically, two workers climb a work scaffold such as a stepladder and engage two ceiling panel temporary receiving jigs 10 attached near the longitudinal end of the ceiling panel 6 with the beam 2, respectively. ..
More specifically, each of the two workers hooks the engaging portion 22 of the skeleton engaging member 20 included in the ceiling panel temporary receiving jig 10 on the flange 2A at the upper part of the beam 2, and flanges the mounting portion 21. Place it on the upper surface of 2A.

(Ceiling panel suspension process)
In the ceiling panel suspension step (FIG. 6, step S4), the ceiling panel 6 is suspended from the beam 2 so as to be substantially vertical. Specifically, the ceiling panel 6 is suspended from the beam 2 so that the surface surrounded by the outer frame member 6A and the connecting member 6C constituting the outer periphery of the ceiling panel 6 is substantially vertical (FIG. 5). At this time, as shown in FIG. 7, a space SP is secured above between the suspended ceiling panels 6. This space SP is a space corresponding to a position where the ceiling panel 6 is mounted in the first ceiling panel mounting step and the second ceiling panel mounting step described later.

When temporarily receiving the ceiling panel 6, it is usually conceivable to temporarily fix the space SP so as to close it with the surface of the ceiling panel 6 (in other words, so that the surface of the ceiling panel 6 is horizontal to the ground). However, the space above the worker's head is blocked, and it becomes difficult to work in the space corresponding to the ceiling and to install the heat insulating material.

As shown in FIGS. 5 and 7, in the ceiling panel construction method according to the present embodiment, the ceiling panel 6 does not block the overhead space in the state where the ceiling panel 6 is temporarily received, and the space above the operator's head. By securing the SP, it becomes easy to perform wiring work and work of installing a drainage pipe on the upper floor at a position corresponding to the ceiling.

(1st ceiling panel mounting process)
In the first ceiling panel mounting step (FIG. 6, step S5), the ceiling panel 6 is fixed to the beam 2. Specifically, as shown in FIGS. 7 and 8, the temporarily received ceiling panel 6 is lifted to the mounting position, and is conventionally known for the beam 2 (strictly speaking, the jig fixed to the beam 2). After fixing by the method, the ceiling panel temporary receiving jig 10 is removed. Specifically, the panel fixing member 30 is removed from the ceiling panel 6 by loosening the screw 6D and lifting the panel fixing member 30. Then, the operating portion 23 is operated so as to be lifted upward, and the skeleton engaging member 20 is removed from the flange 2A of the beam 2.

(Insulation material construction process)
In the heat insulating material construction process (FIG. 6, step S6), in the ceiling panel mounting process, the ceiling panel 6 (first ceiling panel) is fixed to the beam 2, and then the adjacent ceiling panel 6 (second ceiling panel) is attached to the beam 2. Before fixing to, a heat insulating material is arranged on the fixed ceiling panel 6 (first ceiling panel). At this time, as shown in FIG. 8, the space SP1 is secured at a position adjacent to the fixed ceiling panel 6. This space SP1 is a space corresponding to a position where the ceiling panel 6 (second ceiling panel) adjacent to the fixed ceiling panel 6 (first ceiling panel) is mounted in the next second ceiling panel mounting step.

When the ceiling panel 6 is suspended from the beam 2 so as to be substantially horizontal, the work time becomes long because it is necessary to insert the heat insulating material through the gap between the grids of the ceiling panel 6. In the present embodiment, since the worker can arrange the heat insulating material (not shown) on the fixed ceiling panel 6 (first ceiling panel) via the space SP1 (FIG. 8), the heat insulating material is provided. Construction can be done in a short time.

(Second ceiling panel mounting process)
In the second ceiling panel mounting step (FIG. 6, step S7), the ceiling panel 6 (second ceiling panel) adjacent to the ceiling panel 6 (first ceiling panel) mounted in the first ceiling panel mounting step is lifted to the mounting position. , Fixed to the beam 2 (strictly speaking, the pier fixed to the beam 2). Specifically, the ceiling panel 6 (second ceiling panel) temporarily received as shown in FIG. 8 was fixed to the beam 2 by a conventionally known method in the same procedure as the first ceiling panel mounting process. Later, the ceiling panel temporary receiving jig 10 is removed.

Then, by repeating the first ceiling panel mounting step, the heat insulating material construction step, and the second ceiling panel mounting step, the ceiling panel construction is sequentially performed together with the heat insulating material construction. The ceiling panel 6 is attached to the beam 2 (framework) constituting the building 1 by the ceiling panel construction method according to the present embodiment in which the above steps are performed.

When the ceiling panel construction method according to the present embodiment is performed by a pair of two people, the stepladders are installed separately, and each worker has an engagement process, a ceiling panel suspension process, and a first ceiling panel installation process. By sequentially performing the heat insulating material construction process and the second ceiling panel mounting process, the work time can be further shortened as compared with the one-person work.

Further, in the ceiling panel construction method according to the present embodiment, in the heat insulating material construction step, the space SP1 is secured at a position adjacent to the ceiling panel 6 fixed in the first ceiling panel mounting step, so that the grid of the ceiling panel 6 is secured. Since it is possible to construct a heat insulating material having a size that cannot be inserted through the gap between the ceiling panels 6, the total work time including the construction of the ceiling panel 6 and the heat insulating material is significantly shortened.

Further, in the ceiling panel construction method according to the present embodiment, the ceiling panel 6 is suspended from the beam 2 so as to be substantially vertical in the ceiling panel suspension process, but the ceiling is in a state after the ceiling panel 6 is attached. Since the panel 6 is substantially horizontal, it is clear whether or not the ceiling panel 6 is finally fixed, and the completion of the work can be easily confirmed.

Further, in the ceiling panel construction method according to the present embodiment, the ceiling panel 6 is suspended from the beam 2 so as to be substantially vertical in the ceiling panel suspension process, and the ceiling panel 6 is suspended upward between the suspended ceiling panels 6. Since the space SP is secured, it is not necessary to bend down when climbing the stepladder, and the work at the position corresponding to the ceiling can be performed without burden. In other words, it is possible to reduce the time and labor required for building construction work.
