Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a construction panel mainly used for interior wall panels. [1] This relates to a film formation method.

For example, if a material with high moisture permeability such as rock wool felt is used as a filler for the panel opening, a vapor barrier layer is used to prevent moisture from permeating.
) is required.

Figure 1 shows the conventional structure of this type of interior wall panel, in which rock wool felt as a Vlfr thermal material is inserted into the opening of a frame (3) consisting of wooden vertical bars (11 (11) and horizontal bars +21 (21)). 4), and in order to prevent moisture from passing through the rock wool felt (4) part,
A moisture-proof synthetic resin film (5) such as a polypropylene film is adhered to only one surface.

However, this structure requires an adhesive for pasting the synthetic resin film (5), which has the drawback of increasing costs.

The present invention was made with the aim of eliminating such drawbacks.In the present invention, the entire panel is wrapped with a moisture-proof synthetic resin film, thereby eliminating the need for the adhesive and, on the other hand, eliminating the need for internal dew condensation caused by the overall packaging. The problem was solved by forming a large number of through holes on one side only, and then forming the through holes by utilizing the shrinkage of the film due to shrink wrapping.1. It is designed to be easy to do.

Hereinafter, the method of the present invention will be explained based on the embodiments shown in FIG. Inner wall panels (6) filled with rock wool felt (4) for insulation
), the entire inner wall panel (6) is wrapped with a moisture-proof synthetic resin film (11) such as a polypropylene film. In this embodiment, as shown in FIG. 3, a large number of layers are applied over a portion of the synthetic resin film (11), that is, an area that corresponds to one side when the inner wall panel (6) is packaged. Depth of cut (12) (12)...
By forming the film (11) as a whole and heat-shrinking the entire film (11), the film (11) is brought into close contact with the panel (6), and at the same time the cuts (12) (12).

Through hole (13) (13) on one side of panel (6)

In the above, the method of wrapping the film (11) in the panel (6) is to form the film (11) into a bag shape in advance and cover the panel (6) with the film (11).
) and close the opening end by welding, or wrap the sheet directly around the panel (6) and weld each end. Since it can be closed by welding without using adhesive, it can be implemented at a lower cost. In addition, the formation of the cuts (13) (13)... can be performed before the film (11) is wrapped with the panel (6) and heat-shrinked as described above, or before the film (11) is wrapped with the panel (6). It is conceivable that the method is carried out in a sheet-like state, but any method may be used. In short, in the present invention,
This includes all of the cases where it is formed at a stage before being heated and shrunk.

In addition, as mentioned above, the panel (
6) By packaging the entire part, the amount of film (11) used increases compared to the conventional method, and the through hole (13)
Although it is necessary to form (13)..., even if such cost is taken into account, the method of the present invention can be manufactured at a much lower cost.

As described above, according to the present invention, by wrapping the entire panel with a synthetic resin film, there is no need to use an expensive adhesive for bonding the synthetic resin film to the panel, and the panel can be manufactured at low cost. On the other hand, since a large number of through holes are formed in the membrane, which is not considered to be a moisture-proof membrane, it has the effect of sufficiently solving the problem of internal condensation. Furthermore, in the present invention, in order to form such a through hole, a cut is formed in advance and this cut is enlarged using shrink wrapping, so the formation of such a through hole can be easily performed. 9) There are ripples. In other words, one possible method for forming such a through hole is, for example, to hollow out the tip of a heated circular part, but in this case, it is necessary to remove the hollowed out pieces one after another, which is a disadvantage that it requires a lot of effort. However, in the present invention, it is sufficient to simply make a notch, which is much more efficient and can be carried out at a lower cost.

Claims (1)

[Claims] By forming a large number of cuts in a portion of a moisture-proof synthetic resin film and shrink-wrapping the entire panel with the film, a large number of through holes obtained by enlarging the cuts can be created on one side, while the other side is covered with holes.
