Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a case ceiling material forming a case ceiling in a building room.

[Prior Art] Conventionally, as shown in FIG. 9, for example, a ceiling plate 32 is fixed to a main ceiling material main body 31 formed in a lattice frame shape with nails or the like to form each grid 33 of the main ceiling material 31 as shown in FIG. Ceiling board 32 was facing to ~ 33.

[Problems to be Solved by the Invention] However, in the above-described case ceiling material, since the ceiling plate 32 is fixed to the case ceiling material main body 31, there is a problem that skill is required to form it accurately into a frame shape. Was there.

Therefore, the present invention is intended to provide a case ceiling material that can be easily and accurately assembled with a case ceiling material, thereby solving the problems of the prior art.

[Means for Solving the Problem] That is, according to the present invention, a trapezoidal curtain plate is formed by forming both ends on inclined end faces of 45 degrees and penetrating through the bolt insertion play holes vertically to the inclined end faces. A square ceiling outer frame is formed by the curtain plate by abuttingly connecting the inclined end faces of the curtain plate with through bolts and nuts inserted through the bolt insertion play holes. It is a summary.

[Operation] According to the present invention as described above, in the state of being installed on the ceiling, at the time of manufacture, the position of the abutting inclined end surface of the curtain plate constituting the ceiling outer frame mainly composed of the ceiling material is inserted into the play hole for the through bolt. Finely adjust by moving the and tighten the through bolts and nuts to assemble the outer frame to the desired shape.

[Embodiment] Next, the illustrated embodiment of the present invention will be described. The case ceiling material 1 of this example is composed of a case ceiling material main body 2 and a required number of ceiling plates 3, and the case ceiling material main body 2 is inclined at both ends by 45 degrees. A trapezoidal curtain plate 6 is formed on the end face 4 and vertically penetrates the bolt insertion play hole 5 to the inclined end face 4, and the curtain plates 6 and 6 are formed by the through bolts and nuts 8 inserted into the play hole 5. Inclined end faces 4, 4
The ceiling outer frame 9 in the shape of a rectangular frame is formed by the front and rear and left and right curtain plates 6 to 6 that are abutted and connected.

In the case ceiling material 1 of this example as described above, the ceiling outer frame 9 is fixed to the hanging tree 19 hung from the back of the ceiling with nails 20 and the long ceiling plate is attached to the lower outer periphery of the ceiling outer frame 9. 21 is installed. Further, in manufacturing, the curtain bolts 6, 6 constituting the ceiling outer frame 9 mainly composed of the case ceiling material are fitted with the through bolts 7 at the positions of the slanted end faces 4, 4 which abut against each other.
The ceiling outer frame 9 is assembled in a desired form by finely adjusting the movement of the play hole 5 with respect to and tightening the through bolt 7 and the nut 8.

[Advantages of the Invention] As described above, in the present invention, the position of the inclined end surface where the curtain plate abuts is easily fine-tuned by the movement of the play hole with respect to the through bolt, and the ceiling outer frame is accurately formed into a desired shape. Can be assembled.
