Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling support structure in which side edges of an upper panel constituting a ceiling panel are arranged and mounted on both sides of an upper surface of a ceiling beam suspended on a ceiling.

[0002]

2. Description of the Related Art Conventionally, on the back ceiling of a house,
As shown in FIG. 4, there is known a ceiling support structure in which side edges of an upper surface plate 8 constituting a ceiling panel 7 are arranged and mounted on both sides of an upper surface of a ceiling beam 6 suspended on the ceiling. In this case, the main body of the ceiling panel 7 is made of a heat insulating material, and the top plate 8 is made of wood plywood. The ceiling beam 6 is made of wooden timber, and its cross-sectional shape is a vertically long rectangular shape.

However, in this case, since the ceiling beam 6 is made of wooden timber, the ceiling panel 7 which is heavy and is insulated is likely to be insufficient in strength to support the ceiling panel 7 without fail. I couldn't do that. In addition, there is no heat insulating material in the portion of the ceiling beam 6 and its vicinity, and there is a structure in which heat insulation is not provided in the vicinity of the ceiling beam 6, and the heat insulating performance between the room and the inside of the ceiling is low. It was not sufficiently retained.

[0005] As shown in FIG. 5, a wooden material 5 is placed on the outer surface of an upper side 1 and a lower side 2 of a metal mold material 4 having a substantially D-shaped cross section including an upper side 1, a lower side 2, and a middle side 3. A fixed ceiling beam 6 has also been proposed. In this case, an upper surface plate 8 constituting a ceiling panel 7 is provided on both sides of the upper surface of the wooden material 5 on the upper side 1 of the ceiling beam 6 laid on the ceiling. Ceiling support structure in which the side edge portions of are arranged and mounted. Here, the ceiling panel 7 is formed by sticking and integrating an upper surface plate 8 and a lower surface plate 14 on both sides of a rectangular frame member 13 in which a heat insulating material 12 is filled.

In this case, the ceiling panel 7 is filled with the heat insulating material 12 and becomes heavy, but the ceiling panel 7 is sandwiched between the strong ceiling beams 2 mainly composed of the metal mold member 4 having a substantially D-shaped cross section. 7 is securely supported. However, as in the case described above, the heat insulating property is not provided near the ceiling beam 6, so that the heat insulating performance between the room and the inside of the ceiling is not sufficiently maintained.

In particular, in this case, since the main part of the ceiling beam 6 is made of the metal mold 4, heat is easily transmitted between the upper and lower sides of the upper side 1 of the metal mold 4, and the lower surface of the upper side 1 is formed. Easily formed dew. Furthermore, the metal mold 4
In some cases, heat is transmitted through the entire surface, and dew condensation may occur on the surface of the middle side 3 and the lower side 2 of the metal mold 4 or on the indoor side surface.

[0007]

SUMMARY OF THE INVENTION The present invention was invented in order to solve all the problems in the prior art described above, and its object is to ensure the heat insulation performance between the room and the ceiling, An object of the present invention is to provide a ceiling support structure in which condensation is prevented from occurring.

A heat insulating member is mounted on the side edge portions of the upper surface plate on both sides, and a protrusion protruding from the lower surface of the heat insulating member is provided on the side edge of the upper surface plate on both sides. The gap between the ends is engaged.

Therefore, in this case, the main body of the ceiling beam is made of a metal member having a substantially D-shaped cross section, and the ceiling beam is strong, so that even a heavy ceiling panel can be reliably supported. can do. Further, since a wooden beam is fixed to the outer surface of the upper side and the lower side of the metal mold having a substantially D-shaped cross section to form a ceiling beam, a shed bundle is erected and fixed on the ceiling beam. The fixing work for attaching and fixing the indoor-side surface ceiling material under the beam can be easily and reliably performed by using the above-mentioned upper and lower wooden materials.

In addition, on both sides of the upper surface of the wooden material on the upper side of the ceiling beam laid on the ceiling, side edges of the upper panel constituting the ceiling panel are arranged and mounted. Since the heat insulating member is placed on the edge portion, the heat insulating member has a structure in which heat insulating properties are provided in the vicinity of the ceiling beam, and the heat insulating performance between the room and the space above the ceiling is sufficiently ensured. Therefore, even if the main body of the ceiling beam is made of a metal mold material that easily conducts heat, dew condensation around the ceiling beam is prevented.

Further, since the side edges of the top plate constituting the ceiling panel are arranged and mounted with a gap between the side edges, the gap is used as a guideline for a predetermined position where dew-proof measures are required. The heat insulating member can be easily mounted on the pallet.
Also, at this time, since the protrusion projecting from the lower surface of the heat insulating member is engaged with the gap between the side edges of the upper surface plate, the heat insulating member is positioned and securely mounted and fixed so as not to move. .

Therefore, in this case, especially, the ceiling panel is formed by adhering and integrating the upper surface plate and the lower surface plate on both sides of the rectangular frame material in which the heat insulating material is filled. Sufficient heat insulation performance can be obtained in the area of the ceiling panel. Moreover, since the heat insulating member is formed in a strip shape having a width dimension capable of covering up to the rectangular frame material of the ceiling panel disposed on both sides of the ceiling beam, the heat insulating material of the strip plate and the heat insulating material of the ceiling panel are formed. As a result, the entire ceiling plane is continuously covered and insulated, and the heat insulation performance is further improved.

According to a third aspect of the present invention, there is provided a ceiling support structure comprising:
The ceiling support structure according to the second aspect is characterized in that a rib-like projection along the longitudinal direction of the strip is integrally formed on the lower surface of the heat insulating member.

Therefore, in this case, in particular, since the projection formed on the lower surface of the heat insulating member has a rib shape along the longitudinal direction of the strip, the projection is formed over the entire length in the longitudinal direction. And the heat insulating member is more easily and reliably mounted and fixed. Further, the rib-shaped projections in the longitudinal direction can be easily formed integrally with the lower surface of the strip-shaped heat insulating member by foaming resin molding or the like.
