As shown in these drawings, the ceiling material fixing bracket 11 includes a lower bracket 12 having an inverted hat-shaped cross section and an upper bracket 13 having an inverted hat-shaped cross section and arranged above the lower bracket 12 as described above. , A fixing bolt 14 that penetrates the upper and lower metal fittings 12 and 13 in the widthwise direction (horizontal direction in FIG. 5) from the lower side to the upper position, and the upper metal fitting 13 is fixed so as not to come off from the fixing bolt 14. It is provided with a collar 15 fixed to the bolt 14 and a nut (nut is not shown) screwed onto the fixing bolt 14 above the collar 15.

In the ceiling material fixing metal fitting 11 of this embodiment, the bolt insertion hole 12b of the lower metal fitting 12 is located at the center position of the lower metal fitting 12 in the longitudinal direction (horizontal direction in FIG. 7), but the bolt of the upper metal fitting 13 is fixed. The position of the insertion hole 13b is deviated forward (to the right in FIG. 7) from the central position of the upper metal fitting 13 in the longitudinal direction. That is, the front end position of the upper fitting 13 is retracted from the front end position of the lower fitting 12. Further, the lower metal fitting 12 has a bolt rotation preventing projection 12c formed by making a notch in a portion which will be the bolt insertion hole 12b and standing up. Further, the fixing bolt 14 is a square bolt (a bolt having a quadrangular head) and has a sufficiently large engagement margin with the opposing bolt detent protrusion 12c, so that the bolt detent protrusion 12c effectively prevents rotation.

The ceiling material fixing bracket 11 fixes the ceiling material 1 to the H-section steel base material 2 in a manner substantially similar to that shown in FIGS. 3 and 4. That is, although illustrations corresponding to FIGS. 3 and 4 are omitted, the lip portion 1c of the ceiling material 1 is attached to the upper and lower metal fittings 13,
It is sandwiched between the flat parts 13a, 12a of 12, and the fixing bolt 14 is passed through the mounting hole 2b formed in the flange part 2a of the H-shaped steel base material 2, and the nut is screwed and tightened. The procedure for this case is to set the ceiling material fixing metal fitting 11 to the lip portion 1c of the ceiling material 1 first (the lip portion 1c is placed in the gap between the flat portions 13a, 12a of the upper and lower metal fittings 13, 12) as described above. insert). At that time, hold both edges of the left and right flat portions 13a of the upper metal fitting 13 with one hand, incline forward and downward (rightward downward in FIG. 11) as shown in FIG. 11, and move substantially horizontally as indicated by the arrow. Then, the lip portion 1c of the ceiling material 1 is inserted into the gap between the upper and lower flat portions 12a and 13a.

In this case, when the upper metal fitting 13 is held by hand, the lower metal fitting 12 'tilts forward and downward due to the imbalance of the center of gravity, so that the gap between the upper and lower metal fittings 12', 13 further expands at the front end side, and the ceiling The work of inserting into the lip portion 1c of the material 1 becomes easier.

Although not shown, the bolt insertion hole of the upper metal fitting is located at the center position in the longitudinal direction, and the bolt insertion hole of the lower metal fitting is deviated rearward from the center position in the longitudinal direction so that the front end position of the upper metal fitting is lowered. You may retreat from the front-end position of a metal fitting. Also in this case, the upper surface of the lower metal fitting on the front end side is the lip portion 1c of the ceiling material 1.
Is a guide for guiding the ceiling material, and it is easy to set the ceiling material fixing bracket on the lip portion 1c of the ceiling material.

In each of the above-mentioned embodiments, the upper and lower metal fittings have the same length. However, by changing the lengths of the upper and lower metal fittings, even if the front end position of the upper metal fitting is retracted from the front end position of the lower metal fitting. Good. That is, for example, even when the positions of the bolt insertion holes of the upper metal fitting and the lower metal fitting are both at the center positions in the longitudinal direction, the length of the upper metal fitting is shortened so that the tip end position of the upper metal fitting in the longitudinal direction becomes the longitudinal length of the lower metal fitting. It can also be retracted from the tip position in the direction. Also in this case, the upper surface on the front end side of the lower metal fitting serves as a guide for guiding the lip portion 1c of the ceiling material 1, and the work of setting the ceiling material fixing metal fitting on the lip portion 1c of the ceiling material is easy.

The cross-sectional shape of the ceiling material targeted by the present invention is not necessarily limited to that shown in the drawings. For example,
The ceiling material 1 of the above-described embodiment is also applicable to the ceiling material without the downward protruding piece 1d at the tip of the lip portion 1c. In short, it is sufficient if it has a cross-sectional shape having left and right side plate portions and lip portions extending inward. In the case of the cross-sectional shape without the downward projecting piece 1d, the upper and lower metal fittings 12 and 13 are not necessarily the deep inverted hat type as shown, but may be close to flat.

The ceiling structural member for fixing the ceiling material is
Not only the H-shaped steel base material 2 of the embodiment, but also a channel steel base material or a simple beam may be used. Absent. In short, any ceiling structural member having a horizontal plate portion having a mounting hole into which a vertical fixing bolt is inserted may be used. Further, the application itself of the ceiling material targeted by the present invention is not limited to the purpose of improving the aesthetic appearance as described above, but may be, for example, the purpose of soundproofing or any other purpose.
