Abstract

(57) [Summary] [Purpose] To improve workability while improving finish accuracy. [Structure] A structure of a ceiling that forms a recess 1 that is recessed upward. A deformable retaining member 3 having an L-shaped cross section having the same specifications as the ceiling material 2 is provided on the protruding portion of the lower edge of the recess 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceiling structure, and more particularly to a technique for improving workability while improving finish accuracy.

[0002]

[Prior art]

 Conventionally, in the structure of a ceiling that forms a recess that is recessed upwards, the recess is constructed by cutting or cutting the ceiling material on-site, or at a location corresponding to the lower edge of the recess. This part is prefabricated into an L shape at the factory.

[0003]

[Problems to be solved by the device]

 However, it is difficult to obtain a good finishing accuracy due to the error of the shape of the ceiling base and the manufacturing error when the ceiling material is butted against the L-shape in the site-matched construction. Had a problem in that it did not follow the shape of the ceiling base, which is a handmade construction, and the construction was troublesome.

The present invention is intended to solve such a problem, and an object thereof is to provide a ceiling structure capable of improving workability while improving finish accuracy.

[0005]

[Means for Solving the Problems]

 The present invention is a structure of a ceiling that forms a recessed portion 1 that is recessed upward, and a deformable housing member having an L-shaped cross-section with the same specifications as the ceiling material 2 at the protruding corner portion of the lower edge of the recessed portion 1. It is characterized in that 3 is constructed.

[0006]

[Action]

 By the deformation of the retaining member 3, it follows the shape of the ceiling base of the projected corner of the lower edge of the recess 1. Improves workability and finish accuracy.

[0007]

【Example】

 A dent 1 is formed on the ceiling so as to be recessed upward. The ceiling material 2 is installed on the ceiling including the recessed portion 1 along the ceiling substrate 7. Then, a deformable retaining member 3 having an L-shaped cross section having the same specifications as the ceiling material 2 is provided on the protruding portion of the lower edge of the recess 1. As shown in FIG. 1 (b), this retaining member 3 has the same specifications as the ceiling material 2 and the end portions of the inorganic ceiling plates 4 and 4 are cut, and an elastically displaceable packing 5 is interposed at the butting position. It is a thing.

In this way, the deformable retaining member 3 having an L-shaped cross section having the same specifications as the ceiling material 2 is applied to the protruding portion of the lower edge of the recessed portion 1, and the recessed portion is formed by the deformation of the retaining member 3. It is possible to follow the shape of the ceiling base 7 at the outer corner of the lower edge of No. 1 and improve the workability as well as the finish accuracy. FIG. 2 shows another embodiment of the retaining member 3, in which a concave groove 6 is formed on the back surface of the inorganic ceiling plate 4 over its entire length, and the concave groove 6 is deformed.

As described above, the design of the deformable configuration of the retaining member 3 can be changed in various ways.

[0010]

[Effect of device]

 As described above, according to the present invention, since the deformable retaining member having the same L-shaped cross section as the ceiling material is installed at the protruding portion of the lower edge of the recessed portion, the deformation of the retaining member causes the lower portion of the recessed portion to be deformed. It has the advantage that it can conform to the shape of the ceiling base material at the corners of the edges, and improve the workability as well as the finishing accuracy.
