The second, when bending the connecting piece 78, because it can be bent only at the base, the vertical width H of the projection 86 of the MeToru ceiling construction brackets 63, the outbound width B ₅ of connecting piece 78 It was a fixed constant value, and it was sometimes difficult to insert the joint groove depending on the groove width of the joint groove.

In view of the circumstances described above, an object of the present invention is to provide a metal ceiling ceiling fitting which can be easily inserted into a joint groove to a predetermined depth.

[0009]

In order to achieve the above object, the present invention provides a rectangular upper wall having a nail hole in the center, and a pair of rectangles extending vertically downward from both side edges in the width direction of the upper wall. First and second locking pieces protruding laterally from the lower edge of each side wall and slightly descending from the base end to the tip side; A pair of tongue-shaped pieces extending horizontally from both ends in the longitudinal direction to the first locking piece, a pair of connecting pieces extending laterally from both ends in the longitudinal direction of the tip of the second locking piece, and a pair of connecting pieces. By providing a pair of joint plate holding pieces extending laterally from the tip, by inserting a convex portion above the joint groove of the vertical rail of the transparent ceiling plate between the first locking piece and both tongue-shaped pieces. The joint plate is temporarily fixed to the see-through ceiling plate, and a part of the joint plate is surrounded by the second locking piece, both connecting pieces, and both joint plate holding pieces. In the through-hole ceiling metal fitting to be held, around the nail hole, the upper surface forms a horizontal surface, and the height of the horizontal surface is the same as or higher than the height of the upper surface of the tongue-shaped part. A sub-protrusion provided on the upper wall, the upper surface of each of which forms a horizontal plane between the nail-hole peripheral ridge and the tongue-shaped pieces, and the height of the horizontal plane is the same as the upper surface of the nail-hole peripheral ridge; And the width of both connecting pieces is substantially uniform within a range of 1 to 5 mm,
The length of both connection pieces is the same as or longer than the thickness of the joint plate, and a metal fitting for a transparent ceiling construction is provided.

[0010] The metal ceiling ceiling fitting of the present invention has a protruding portion around the nail hole around the nail hole, so that it can be attached in parallel to the ceiling construction base material by nailing. In addition, since there is a pair of sub-protrusions having the same height surface as the nail-hole surrounding ridge between the nail-hole surrounding ridge and both tongue-shaped pieces, the transparent ceiling metal fitting is parallel to the ceiling base material. Installation becomes even easier. Therefore, the vertical width of the convex portion is uniform, and the convex portion can always be easily inserted to a predetermined depth of the joint groove.

When the joint plate is held by surrounding the portion, the joint plate can be bent at an arbitrary position of the connecting piece so that the joint plate is involved. Therefore, the vertical width of the protrusion formed by bending the second locking piece, the connection piece, and the joint plate holding piece can be set to a value corresponding to the groove width of the joint groove. It can always be easily fitted into the device. In the present invention, preferably, the width of the connection piece is substantially uniform within a range of 1.5 mm to 4.5 mm, particularly 2 mm to 3.5 mm.
