This relates to a ceiling structure characterized in that the lower end of the hanging tree 14 is fixed to the hanging tree fixing piece 6 by being sandwiched between the upper surface part and the part outside the metal fitting mounting groove 16. .

Conventionally, when constructing a ceiling, the construction was complicated because many parts such as pole edges, field edges, etc. were required.In particular, construction between ceiling panels and pole edges, field edges, hanging trees, etc. required a lot of work. The drawback was that it was time consuming.

The present invention has been made in view of the above points, and its purpose is to allow the ceiling plate and the pole edge to be attached simultaneously and easily around the edge, and to attach the long edge of the adjacent ceiling plate. To provide a ceiling structure in which the adhesion of joints formed at pole edges is strong, a ceiling board can be easily hung on a hanging tree, and a pole edge or a field edge is not required.

The present invention will be explained in detail below by means of illustrated embodiments. The fixing fittings 7 are for fixing the opposing rod edges 9 and long side edges 8 of two adjacent ceiling panels 12, and as shown in FIG. 1 and a convex arc-shaped short side 2 that is shorter than the long side 1. At the top of the shaft body 4, an elastic horizontal plate-shaped holding piece 5 is formed on the long side. Part 1
They protrude in both directions parallel to the . In this case, the nail head-like part 3 has a dimension between both long sides 1 that is smaller than the width of a metal fitting groove 16 formed in the rod edge 9 of the ceiling board 12, which will be described later, and a space between both arc-shaped short sides 2. The dimensions are larger than the width of the metal fitting groove 16, and the dimension between the lower surface of the nail head 3 and the lower surface of the holding piece 5 is approximately the same as the dimension between the upper surface of the ceiling plate 12 and the bottom surface of the metal fitting groove 16. It is set as. Both sides parallel to the long side 1 of each presser piece 5 are bent upward, and the upper part of the fixing bracket 7, which is extended by bending the base of each presser piece 5 upward, is attached at both front and rear ends. A hanging tree fixing piece 6 is provided protruding from the side of the holding piece 5 on the opposite side from the surface, and a plurality of hanging tree fixing pieces 6 are provided on each hanging tree fixing piece 6 that is substantially perpendicular to the holding piece 5 above the opposing holding piece 5. A mounting hole 15 is bored. The ceiling board 12, such as a synthetic resin board or a gypsum board, has a substantially rectangular shape consisting of a long edge 8 and a short edge 10 shorter than the long edge, as shown in FIG. A rod edge 9 having a substantially U-shaped cross section is provided on the edge 8a and protrudes downward over approximately the entire length, integrally with the ceiling plate 12, and the outer piece 9a of the rod edge 9 is in contact with the upper surface of the ceiling plate 12. The inside of the rod edge 9 is substantially flush with the metal fitting groove 16. Therefore, when constructing the ceiling, first attach the circumferential edge 11 to the wall surface around the ceiling, and at the same time cut out the upper part of the inner peripheral surface at regular intervals on one opposing side of the circumferential edge 11 to form a plurality of fitting notches 13. will be established. Next, the required dimensions of the plurality of ceiling panels 12 are assigned and the short edge portions 10 are
(width of the ceiling board) is too wide, cut the long edge 8b side of the side where the rod edge 9 does not exist to adjust the width of the ceiling board 12, and then cut the long side of the first ceiling board 12. Edge 8
b and the short edge 10, and place it on the upper end surface of the edge 11, and fit the end of the short edge 10 side of the rod edge 9 into the fitting notch 13, and then connect the long edge 8b and the short edge. Part 10
is fixed to the circumferential edge 11 with a fixing device 17 such as a nail,
Similarly, the rod edge 9 is fixed to the surrounding edge 11 using a fixing tool 17 driven from the metal fitting groove 16. 2 fixed to the upper end surface of the edge 11 around the short edge part 10 with the fixing tool 17
Place the long edge 8b of the second ceiling board 12 on the outer piece 9a of the first ceiling board 12 (that is, the part outside the metal fitting groove 16 on the top surface of the pole edge 9). Then, as shown in FIGS. 4a and 4b, insert the nail head-shaped part 3 of the fixing metal fitting 7 into the metal fitting groove 16 of the first rod edge 9 so that the long side 1 is parallel to the longitudinal direction of the metal fitting groove 16. Insert it so that it is, and rotate the fixing metal fitting 7 approximately 90 degrees. When the fixing bracket 7 is rotated approximately 90 degrees, the dimension between the two arcuate short sides 2 is larger than the width of the bracket mounting groove 16, so the arcuate short side 2 bites into the inner wall of the bracket mounting groove 16 and is fixed. The metal fitting 7 is fixed to the first ceiling board 12, and at the same time, one of the presser pieces 5 comes into contact with the upper surface of the first ceiling plate 12, and the other presser piece 5 is elasticized by the thickness of the ceiling plate 12. The long side edge 8b of the second ceiling board 12 is bent upward to
from above to the outer piece 9a side, and the long edge 8b of the second ceiling plate 12 is the part outside the other holding piece 5 and the metal fitting groove 16 on the upper surface of the rod edge 9. It is firmly clamped between the outer pieces 9a. In the same manner, a plurality of fixing metal fittings 7 are attached in the longitudinal direction of the rod edge 9, and the second ceiling plate 12 is attached to the rod edge 9 of the first ceiling plate 12 using the holding piece 5 of each of the fixing metal fittings 7. Fix it firmly. Then the top end is covered with a roof beam (not shown)
The lower part of the hanging tree 14 fixed to the metal fittings 14 is brought into contact with the hanging tree fixing piece 6 of the fixing metal fitting 7 inserted into the metal fitting groove 16, and the lower end of the hanging tree 14 is fixed by driving the fixing tool 17 through each mounting hole 15. Fix it to the metal fitting 7. In the same way, attach the fixing bracket 7 to the rod edge 9 of the second ceiling board 12.
Fix the long edge 8b of the third ceiling board 12 with
Thereafter, a plurality of ceiling panels 12 are sequentially connected to adjacent ceiling panels 1.
It is fixed to the rod edge 9 of No. 2 with a fixing fitting 7 to form a ceiling.

In the present invention, as described above, the rod edge projecting downward from one long side edge of the ceiling board is integrally provided.
The ceiling plate and the rod edge can be easily fixed to the surrounding edge at the same time, and since the rod edge is formed integrally with the ceiling plate, the strength can be improved compared to a separate rod edge. Furthermore, the long edge of the ceiling board that goes around the short edge of the ceiling board and is fixed to the upper end surface of the edge, and that is adjacent to the outer part of the top surface of the rod edge of the ceiling board and that does not have the rod edge of another ceiling board. Place the nail head-shaped part into the metal fitting groove that opens above the rod edge, and attach the arcuate short side to the metal fitting with the long side perpendicular to the longitudinal direction of the metal fitting groove. It dug into the inner wall surface of the groove, and the long edge of the adjacent ceiling plate without the rod edge was sandwiched between the holding piece and the part of the upper surface of the rod edge outside of the metal fitting groove. , the long edge of the adjacent ceiling board is pressed by the holding piece to the part outside the metal fitting groove on the top of the rod edge, and is formed by the long edge of the adjacent ceiling board and the rod edge. The adhesion of the joint is strong, and since the arcuate short side bites into the inner wall surface of the metal fitting mounting groove, the force required to start biting can be reduced (in other words, if the short side to be bitted is not an arc but a straight line, the force required to start biting can be reduced). (However, in order to obtain the desired biting force, the arcuate shape requires less force than a straight line.) The short arcuate side part is sure to bite into the inner wall surface of the metal fitting mounting groove, and a hanging tree fixing piece is provided on the top of the fixing metal fitting that fixes the long edge of the two ceiling panels and the rod edge. Because of this, the hanging tree can be easily attached to the fixing bracket, and unlike conventional ceilings, there is no need for a field edge or separate rod edge for attaching the hanging tree to the ceiling board, which reduces the number of parts. It is possible. In addition, since the rod edge is formed into a substantially U-shaped cross section, the opening in the rod edge serves as a guide when driving in the fastening tool and fixing it around the rod edge, making it easy to drive the fastening tool from the bottom inside the rod edge. It is.
