Description

[Detailed description of the invention] The present invention relates to improving the structure of a heat-insulating ceiling material, and includes forming a ceiling material body 3 by lining the back surface of a surface plate 1 with a synthetic resin foam 2, and one side of this ceiling material body 3. A fitting groove 4 having an approximately U-shaped cross section with an open upper surface is formed at the edge, and a locking part 5 is provided on the opposing inner surface of the fitting groove 4, and the upper part of the other side edge of the ceiling material main body 1 is provided with a locking part 5. A fitting protrusion 6 that can be fitted into the fitting groove 4 is suspended from the fitting protrusion 6, and a locked part 7 that can be locked with the locking part 5 is provided on the fitting protrusion 6. to locked part 7
A hanging part 8 is provided on the back surface of the ceiling material body 1 to allow the lower part of the hanging tool 10 to be slidably hooked in the longitudinal direction. This invention relates to a heat insulating ceiling material that is installed in the longitudinal direction of the walls, and the purpose of this invention is not only to have heat insulating properties, but also to be able to be easily connected and constructed, and to be able to connect so that there are no steps. We provide ceiling materials.

The present invention will be explained in detail below with reference to Examples. Reference numeral 1 denotes a surface plate made of a synthetic resin plate or the like, and the surface is finished in a single color or with printing. In addition, there is a cross on the surface plate 1,
PVC leather, paper, film, metal foil, etc. may also be used. A ceiling material body 3 is formed by lining the back surface of the surface plate 1 with a synthetic resin foam 2 such as urethane foam, isocyanurate foam, styrene foam, or polyethylene foam. A fitting groove 4 having an approximately U-shaped cross section with an open upper surface is provided at the upper part of one side edge of the ceiling material main body 3, and a locking portion 5 is provided on the opposing inner surface of this fitting groove 4. is formed into a serrated shape. A fitting protrusion 6 is suspended from the other side edge of the ceiling material main body 3, and locking portions 7 are formed in a sawtooth shape on both sides of the fitting protrusion 6. The fitting groove 4 and the fitting protrusion 6 can also be formed simultaneously with the surface plate 1 by extrusion molding. A hanging portion 8 having a U-shaped cross section with a lip is provided on the upper surface of the ceiling material body 3 on the side of the fitting protrusion 6 so as to be open at the top. A metal plate may be inserted into this hanging portion 8. Reference numeral 9 is a pack sheet, which may be made of the same material as the surface plate 1 or may be omitted. The heat insulating ceiling material A constructed as described above is constructed as follows. A field edge 12 is attached to the upper end of the hanging tool 10 with a fixing tool 11, and a hook portion 10 in the shape of an inverted T at the lower part of the hanging tool 10 is attached.
a to the hanging part 8 of the insulating ceiling material A, and then attach the insulating ceiling material A to one of the adjacent insulating ceiling materials A.
The fitting protrusion 6 is inserted into the fitting groove 4 of the other heat insulating ceiling material A.
The locking portion 5 and the locked portion 7 are engaged and connected. At this time, by adjusting the locking positions of the locking part 5 and the locked part 7, no step is created between the surfaces of the adjacent heat insulating ceiling materials A.

FIG. 2 also shows another embodiment of the description. Embosses 13 are provided on the surface of the top plate 1. In addition, pearlite, shirasu balloons, glass fibers, etc. are mixed into the synthetic resin foam 2 to improve flame retardancy and dimensional stability. Further, the hanging portion 8, the fitting groove 4, and the fitting protrusion 6 are made of synthetic resin extrusion molding, aluminum extrusion molding, or the like. The pack sheet 9 is paper or aluminum foil. Reference numeral 14 is a buried tree to which lighting equipment and the like can be easily attached.

As described above, this invention forms the main body of the ceiling material by lining the back side of the surface board with synthetic resin foam, so it has insulation properties and can significantly reduce heating and cooling costs. A fitting groove having an approximately U-shaped cross section with an open upper surface is formed on the side edge, and a locking part is provided on the opposing inner surface of the fitting groove, and the fitting groove is inserted from the upper part of the other side edge of the ceiling material main body. A fitting protrusion that can be fitted into the mating groove is suspended, and the fitting protrusion is provided with a locked part that can be locked with the locking part, and either one of the locking part or the locked part is provided. Since the grooves are vertically serrated, it is possible to connect the locking part and the locked part by fitting the fitting grooves and the fitting protrusions of adjacent insulating ceiling materials to lock the locking part and the locked part. This has the advantage that by adjusting the locking position of the locking part and the locked part, it can be constructed so that there are no steps between adjacent insulating ceiling materials. A hanging part that can be slidably hung in the longitudinal direction is provided on the back of the ceiling material body in the longitudinal direction of the ceiling material body, so that by hooking the hanging tool on the hanging part and fixing the hanging tool to the verge. The insulating ceiling material can be easily hung, and the hanging tool can be hung on the hanging part and slid in the longitudinal direction to freely change the position of the hanging tool, making it easy to hang. There is an advantage that the hanger can be fixed and can be easily and reliably attached to the position of the field edge.
