Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ceiling panel mounting device in a small building such as a study room or a temporary dormitory. It is designed such that it can be received and supported by the ridge from the lower inside.

[Conventional technology]

9 and 10 show a conventional structure in which a ridge is used as a supporting member for a ceiling panel in order to save labor in a ceiling suspension structure. Here, the ridges 42 are fixed in advance to the four sides of the frame members of the front and rear and left and right upper frames 41 that surround the four upper edges of the wall panel 40, and a ceiling presser 44 having an L-shaped cross section is separately prepared. Then, after the ceiling panel 45 is sequentially supported by the support wall 43 of the circumference 42, adjacent panels 45 are appropriately joined together to be integrated. Next, as shown in FIG. 10, the ceiling presser 44 was fixed to the four sides of the upper frame 41, and finally the roof was assembled.

[Problems to be solved by the device]

In this way, after the ceiling panel 45 is stretched, the ceiling presser 44 is retrofitted, in particular, the final ceiling panel 45a to be assembled at the end has the ridge 42a located below it as shown by the phantom line in FIG. This is because it is necessary to avoid the final ceiling panel 45a from being lifted if the ceiling presser 44 is attached in advance, because it is necessary to avoid it and lift it in an inclined posture and then support it on the ridge.

Therefore, in the conventional structure, at least the last ceiling presser 44 must be assembled from the upper outer surface side of the ceiling,
The roof could only be assembled after the ceiling had been stretched. Therefore, if there is rainfall or the like before the ceiling assembly is completed, it is necessary to interrupt the work and wait for the weather to recover, which is a disadvantage of the construction depending on the weather.

Of course, if only the final ceiling panel 45a is not lifted, the roof can be assembled prior to the ceiling, but this is not sufficient for lifting control.

Further, if only the rounded edge 42a on the final ceiling panel 45a side is post-assembled, the above problem can be solved. However, in this case, the bolt for fixing the ridge 42a is exposed in the room, or the tool insertion hole for screwing the bolt must be provided in the wall surface of the ridge 42a. It is inevitable that the cutoff effect of 42a will be significantly impaired.

The present invention has been proposed in view of the above, and its purpose is to prevent all ceiling panels from being lifted from the indoor side and to easily assemble them without impairing the effect of the cutoff of the edging. The goal is to prevent the construction opportunity from being lost due to the weather.

[Means for Solving the Problems]

According to the present invention, the three frame members 12, 13, and 15 of the upper frame 2 are provided with a leading edge 24 that also serves as a support member for the ceiling panel 23 along the inner surface thereof, and a ceiling retainer 31 that prevents the ceiling panel 23 from rising. Are arranged above and below, respectively, and the ceiling panel 23 can be mounted between the front edge 24 and the ceiling retainer 31. In many cases, there are several ceiling panels 23 installed between both 24 and 31, but 1
It may be a sheet.

Thus, it is characterized by the rim on the side of the final ceiling panel 23a that is finally mounted. That is, the frame member 14 of the upper frame 2 on the side where the final ceiling panel 23a is mounted is provided with the ceiling pressing member 25 for restricting the rising of the ceiling panel 23a, and the ceiling pressing member 25 is provided below the ceiling pressing member 25. An edge fitting 27 is provided, and a retrofitting edge 26 is provided on the edge fitting 27 so as to cover the outer surface thereof.
The reference numeral 32 is inserted and engaged in a retaining manner between the edge fitting 27 and the final ceiling panel 23a.

[Action]

With respect to the three-side leading edge 24, even if the ceiling presser 31 is provided, the ceiling panel 23 can be fitted and mounted without any trouble. Although the ceiling pressing member 25 is attached in advance when the final ceiling panel 23a is attached, the edging fixture 27 and the retrofitting rim 26 are not yet attached. Therefore, the final ceiling panel 23a can be guided from below the inside of the room and supported between the ridges 24 without any trouble. After that, the rim attachment tool 27 and then the retrofit rim 26 are attached.

Corresponding to the engaging groove 37, engaging ribs 38 are respectively provided on the upper walls 32 of the ridges 24 and 26 so as to project therefrom.

Next, the procedure for assembling the ceiling 22 will be explained. The front edge 24 is fixed to the frame members 12, 13, 15 on the front and rear sides of the upper frame 2 and on the right side,
At the same time, the ceiling pressing member 25 is fixed to the left frame member 14.
In this state, attach both ends of the ceiling panel 23 to the front
And slide it toward the front edge 24 on the right side to insert it between the ceiling retainer 31 and the upper wall 32. In the same manner, several ceiling panels 23 are sequentially assembled, and adjacent portions thereof are tongue-joined to connect the panels 23 to each other. FIG. 4 shows an assembling state in which only the final ceiling panel 23a is left. In addition, each ceiling panel 23 is nailed and fixed to the wood piece inserted in the beam 9 in order.

Finally, the final ceiling panel 23a to be mounted is fitted in the front and rear preliminarily rounded edges 24, and is joined to the preceding ceiling panel 23 to form the ceiling 22. After this, as shown in FIG. 7, the edging fixture 27 is fixed to the wall panel 4 with the bolt 20 via the connecting piece 18. In this state, the ceiling panels 23 and 23a are supported by the leading edge 24, and have a clearance gap with the ceiling retainer 31.

In order to eliminate this interchange gap and prevent the ceiling panels 23 and 23a from moving up and down, a wedge body 28 is driven between the ceiling panels 23 and 23a and the upper wall 32 of the three-sided leading edge 24, and the ceiling panels 23 and 23 23a is closely attached to the ceiling presser foot 31. As shown in FIG. 5, the wedge body 28 is provided with engaging ribs 38 provided on the respective leading edge 24.
