DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ceiling margin forming a ceiling in a room, and more particularly to a structure suitable for forming a composite ceiling composed of a horizontal ceiling and an inclined ceiling connected thereto. It relates to a ceiling margin structure.

[0002]

BACKGROUND ART Conventionally, when building a ceiling of a room,
For example, it is often the case that a ceiling edge is assembled on the upper side of a room, and a ceiling plate is attached to the ceiling edge. As a ceiling edge on which the ceiling plate is attached, one described in Japanese Utility Model Publication No. 4-4087 is known. The ceiling ridges are fixed to the opposing wall surfaces of the room with runners having a U-shaped cross section with openings facing each other. Are fitted. In the ceiling edge of this configuration, the ceiling is formed by fixing a ceiling plate to the lower surface of the edge using a fastening member such as a screw.

[0003] By the way, the ceiling of a room is generally formed horizontally. For example, when a room of a house is extended in the inclination direction of a roof, the ceiling of a portion located below the roof is horizontal. When the ceiling is formed such that the ceiling becomes lower, the space in the room becomes narrower, and it becomes easier to receive a feeling of oppression. Therefore, the ceiling of the part located below the extended roof is a sloped ceiling that is inclined along the slope of the roof, and the edge of the horizontal ceiling of the part that is located below the roof that does not extend is attached to the inclined ceiling. To connect the upper edges. Therefore, when forming a composite ceiling composed of such a horizontal ceiling and a sloping ceiling, it is necessary to provide a sloping part corresponding to the sloping ceiling and a horizontal part corresponding to the horizontal ceiling also in the ceiling rim.

[0004] For the ceiling edge, for example, a horizontal portion and an inclined portion are formed separately, and in the case of metal, the inclined portion is fixed to the end of the horizontal portion by welding, bolts, or the like. In the case of (1), it is fixed by bonding, nailing or the like, or in the case of synthetic resin, by fixing by adhesion, welding or the like. In the case of metal or synthetic resin, the horizontal part and the inclined part may be integrally formed by bending a long member at a predetermined position. In addition, a plate is brought into contact with a boundary portion between the horizontal portion and the inclined portion to reinforce it, and the edges of the ceiling are connected by a connecting member.

[0005]

When designing a house, CAD (Computer Aided Design) is often used. In the ceiling edge structure having the above-described inclined portion, in a plan view, the broken line of the ceiling is usually displayed by a broken line, so that the inclined portion and the horizontal portion can be distinguished, but the positional relationship between the broken line of the ceiling and the base material of the ceiling margin. If (the boundary line between the inclined portion and the horizontal portion) is not set in advance, the boundary between the inclined portion and the horizontal portion cannot be recognized by CAD, which is an obstacle to automatic assignment. In addition, for example, in the case of connecting using a connecting member, the number of members is increased, and the connecting work of the connecting member sometimes requires labor and cost. Furthermore, structurally, for example, at the joint between the horizontal portion and the inclined portion, it is necessary to cut the member of the inclined portion obliquely on site, which has been troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is easy to distinguish between a sloped portion and a horizontal portion of a ceiling edge forming a composite ceiling, thereby facilitating the design by CAD, and reducing the cost and work cost.
