【発明が解決しようとする課題】
然しながら、従来の天井パネルでは、枠材を構成するＣ形鋼の上下のフランジに挟まれる開口に野縁を嵌め込んだものであり、野縁を介して作用する鉛直荷重は該Ｃ形鋼の下フランジに作用し、該下フランジを下向きに開き変位させる。例えば、天井パネルの野縁の上に足場板を取着したとき、足場板から野縁を介して枠材の下フランジに作用する鉛直荷重が該下フランジを大きく開き変位させて、天井パネルの構造強度、形状精度を損なう。
【０００４】

(1) The L-shaped hanging piece 63 is fixed to the side joists 3B of the floor panel 3 of the second-floor building unit 1B. Bolts 65 that are attached to the upper and lower sides of the horizontal plate portion 63A of the hanger 63 via vibration-proof rubbers 64A, 64B, and 64C are used.
[0035]
(2) The long hole portion of the attachment portion 62B of the ceiling panel 60 is inserted into the lower end portion of the bolt 65 of (1) described above, and this is fastened with the nut 66 (FIG. 10).
[0036]
According to this embodiment, there are the following operations.
(1) In the ceiling panel 60, since the upper and lower lips 24, 25 of the C-shaped steel 20 constituting the side field edge 11 of the ceiling framework 14 are connected by the mounting bracket 61, the rigidity of the C-shaped steel 20 is increased. And the opening displacement of the upper and lower flanges 22 and 23 can be suppressed. Thereby, the strength and shape accuracy of the ceiling panel 60 can be secured stably.
[0037]
(2) Since the concave stepped portion 26 is provided at the corner portion on the web 21 side on the upper surface of the side field edge 11 of the ceiling frame 14, the scaffolding plate 17 and fire prevention are provided on the stepped portion 26 of the opposite side field edge 11. Both end portions of the face material can be supported, and the scaffold plate 17 and the fire-proof face material can be stretched on the upper portion of the field edge of the ceiling frame assembly 14.
[0038]
(3) Since the concave stepped portion 26 is provided at the corner on the web 21 side on the upper surface of the side field edge 11 of the ceiling frame 14, the rigidity of the cross section of the side field edge 11 is improved, and thus the ceiling panel 60 Strength and shape accuracy can be improved.
[0039]
(Fourth Embodiment) (FIGS. 11 and 12)
The difference between the ceiling panel 70 of the fourth embodiment and the ceiling panel 10 of the first embodiment is the joint structure of the field edge 12 to the side field edge 11. That is, if the attachment structure of the joint structure of the side field edge 11 and the field edge 12 in the ceiling panel 70 is shown as follows (1) to (4).
[0040]
(1) In the web 21 of the C-shaped steel 20 constituting the side field edge 11, an H-shaped slit 71 for raising two upper and lower cut-and-joined pieces is put in advance at the joint part of the field edge 12.
[0041]
(2) The edge 12 (square steel pipe 30) is abutted against the web 21 provided with the H-shaped slit 71 of the side edge 11.
[0042]
(3) The core 72 is pushed into the H-shaped slit 71 from the inside of the web 21 of the side field edge 11, and the H-shaped slit 71 is expanded to raise and lower the upper and lower joining pieces 21A and 21B, while the field edge 12 ( It enters into the inside of the square steel pipe 30). The cut and raised joining pieces 21A and 21B are overlapped on the upper and lower inner surfaces of the field edge 12 (square steel pipe 30).
[0043]
(4) The upper and lower caulking punches 73A and 73B are moved forward, and the upper and lower surfaces of the field edge 12 (square steel pipe 30) and the upper and lower cut-and-raised joint pieces 21A and 21B are overlapped. The upper and lower caulking punches 73A and 73B and the core 72 are clamped and joined.
[0044]
Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. However, it is included in the present invention. For example, the joining structure of the web 21 and the field edge 12 of the side field edge 11 (C-shaped steel 20) can be made by other methods, and the upper and lower lips 24, 25 of the side field edge 11 (C-shaped steel 20) The fixing structure of the mounting bracket 13 can also be based on other methods.
[0045]
【The invention's effect】
As described above, according to the present invention, in the ceiling panel formed by joining the edge of the field edge to the side surface of the side field edge to constitute the ceiling frame assembly, it is possible to stably ensure the strength and shape accuracy of the ceiling panel. it can.
