Description

[Detailed description of the invention] The present invention relates to a ceiling insulation construction method.

Conventionally, when insulating the ceiling of a building, as shown in Figure 1, a field edge 2 is fixed to the indoor surface of a field edge receiver 1 so as to be perpendicular to the field edge receiver 1, and then A temporary sealing edge, a finishing base material 3 such as plaster or veneer plywood, etc. is fixed to the indoor side surface of the edge 2, and a finishing base material, a field edge, and a field edge support are formed between the finishing base material and the field edge. A method has been used in which a cotton-like heat insulating material 4 is laid in the space, and the indoor side surface of the finishing base material 3 is finished with a finishing material 5 such as cloth or a sound-absorbing board.

However, with this method, it is difficult to pack the insulation material tightly against the finishing base material, etc., and as a result, gaps occur between the insulation materials, resulting in insufficient insulation performance. As a result, the heat insulating material becomes deformed or uneven, resulting in a decrease in heat insulating performance and a time-consuming construction process.

Recently, as shown in Fig. 2, hard urethane foam 1
A method has also been used in which a plate-shaped heat insulating material 12, in which a panel material 11 is laminated only on one side of the indoor side of the room, is interposed between the finishing base material 3 and the edge 2; When fixing the plate-shaped heat insulating material 12 to the edge 1 by nailing or the like from the base material 3 side, the hard urethane foam is compressed, so steps are likely to occur at the joints of the finishing base material 3. If the base material is not stretched neatly, it becomes difficult to perform subsequent construction after fixing the finishing base material, and it also takes time and effort to install, similar to when installing cotton-like insulation.

It is an object of the present invention to eliminate the drawbacks of these conventional methods of insulating the inside of a building, and to provide a method of insulating ceilings that has excellent heat insulating performance and is easy to perform.

That is, the present invention provides a heat insulating panel made of a hard synthetic resin foam made of a moisture-proof surface material laminated on the front and back sides, and a reinforcing material with approximately the same thickness as that of the foam. A reinforcing material of the panel is fixed to the indoor side surface of the panel directly or through a field edge, and then a finishing material is fixed to the indoor side surface of the panel directly or through a finishing base material. .

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 3, moisture-proof surface materials 7 and 7' are laminated on the front and back surfaces of the plate-shaped rigid synthetic resin foam 6, and a layer of the same thickness as the foam 6 is placed inside the rigid synthetic resin foam 6. A panel 9 made up of bar-shaped reinforcing members 8 with a square cross section is placed on the lower surface of the field edge receiver 1 so that the field edge receiver 1 and the reinforcing members 8 are parallel or perpendicular to each other, as shown in FIG. , fix the panel to the edge support 1 by driving nails into the reinforcing material 8 side of the panel, and then temporarily seal or attach a finishing base material 3 such as gypsum board to the reinforcing material 8 of the panel 9 with nails or the like. The fixed finishing material 5 is pasted.

The length L1 width W and thickness T of the panel used in the present invention are:
It is not particularly limited as long as the appropriate value is selected according to the floor plan of the building and the required insulation performance, but generally the length is 91 mm.
Those having a shape of 0 to 2400 mm, width of 455 to 910 mm, and thickness of 15 to 30 mm are used.

The shape of the reinforcing material 8 to be buried in the panel is not particularly limited as long as the surface in contact with the surface material 7.degree. 7' is parallel, but generally a material having a rectangular cross section is used.

The number of reinforcing materials to be buried in the panel may be one or more depending on the size of the panel. When embedding multiple reinforcing materials, the reinforcing materials should be parallel to each other. Alternatively, they may be orthogonal.

The thickness of the reinforcing material between the surface materials 7 and 7' is determined by using synthetic resin foam to fix the reinforcing material and the edge holder with nails, etc., and to attach the finishing base material or finishing material to the panel. It is desirable that the thickness be the same as, or slightly minus, approximately the same.

The rigid synthetic resin foam constituting the panel of the present invention preferably has excellent heat insulation performance and self-adhesive properties, such as rigid polyurethane foam, phenol resin foam, epoxy resin foam, urea resin foam, etc. be.

As a moisture-proof surface material to be laminated to hard synthetic resin foam,
Moisture-proof flexible sheet materials are suitable, such as asphalt roofing paper or plastic films such as polyvinyl chloride film or polyethylene film, as well as kraft paper or kraft paper laminated with plastic film or aluminum foil. A laminate film or the like can be used.

The moisture-proof surface materials for the front and back surfaces may be the same or different. For example, it is preferable to laminate aluminum kraft laminated paper on the indoor side and polyethylene kraft laminate paper on the outdoor side.

To fix a panel to a field edge support, the field edge support and the reinforcing material in the panel must be able to be fixed with fixing tools such as nails, so the field edge support and the reinforcing material in the panel are It is preferable to provide them in the same direction so as to abut each other, or to provide them orthogonally.

Examples of finishing base materials that can be used in the present invention include temporary sealing, plywood plywood, and plaster.

Further, as the finishing material, conventionally known finishing materials such as cloth, sound-absorbing boards, etc. may be appropriately selected and used depending on the type of room and the customer's preference.

Further, in the construction method of the present invention, as shown in FIG. 5, after fixing the panel 9 to the field edge receiver 1, the finishing material can be directly attached to the indoor side surface of the panel 9.

If such a construction method is used, not only the edging but also the finishing base material can be omitted, which further simplifies the construction to a great extent.

As described above, according to the method of the present invention, since a heat insulating panel in which a hard synthetic resin foam, a reinforcing material, and a moisture barrier layer are integrally bonded is used, it can be installed simply by fixing it with nails, etc., and can be installed in the field. The edge bracket simplifies construction because the lower edge can be omitted, and the reinforcing material inside the panel touches the base material, so even if the base material and the insulation panel are fixed with nails etc. at this part, the panel It has many advantages: it makes subsequent construction easier because there are no steps between the parts, it has a high airtightness, so it has a great insulation effect, and it also simplifies construction, greatly reducing construction costs. can get.

Furthermore, since the panels of the present invention can be cut freely, there is an advantage that the length and shape can be freely adjusted and constructed according to changes in the floor plan.
