Description

DETAILED DESCRIPTION OF THE INVENTION "Technical field" The present invention relates to a packaging structure for compressing and packing an inorganic fiber mat in a packaging bag.

“Prior art and its problems” For example, as shown in FIG. 5, a glass fiber mat 1 used as a heat insulating material for walls has a moisture-proof layer 3 on one surface of a heat insulating material body 2 and an outer covering material on the other surface. 4 and is provided with ears 5 extending from the moisture-proof layer 3 on both sides. And
When this is used as a heat insulating material for walls, it is applied with the moisture-proof layer 3 facing the indoor side. Such a glass fiber mat 1
Before use, the plurality of sheets are folded in two and compressed in a packaging bag (not shown) in a laminated state.

In this compression packing, the conventional method of folding the glass fiber mat 1 is as shown in FIG. 3 such that the outer cover material 4 is on the inside and, in other words, the moisture-proof layer 3 is on the outside. ing.

However, in the state of being folded with the jacket material 4 inside,
When the glass fiber mat 1 is compressed and packed in a packaging bag, the following problems occur.

The work efficiency is poor because the moisture-proof layer 3 side cannot be directed to the indoor side unless it is deployed once during construction.

When the expanded glass fiber mat 1 is stopped by applying the ear 5 to the wall studs 8 as a heat insulating material, the lower side is usually
That is, since it is performed from a portion close to the floor, the upper portion which is not fixed may hang down, which may interfere with the fixing work. In addition, when fastening from a place near the ceiling, it may be difficult to carry it to a high place and position it on the stud 8.

When the outer cover material 4 is folded inward and compressed and packed, the air may not be sufficiently deaerated. That is, in order to remove air from the glass fiber mat 1 which is inflated with sufficient air, the mat 1 is usually provided with a large number of small holes 6 for deaeration.
However, since the small hole 6 is formed on the outer cover material 4 side, when the outer cover material 4 is folded inward,
The small holes 6 will be blocked off, resulting in poor deaeration, which will cause some trouble in compression packaging.

"Purpose of Invention" The present invention aims to provide a packaging structure of an inorganic fiber mat which improves work efficiency and workability during construction work and is easy to pack by compression.

[Outline of Device] In order to achieve the above object, one surface of the present invention is a moisture-proof layer,
The other side is covered with a covering material, and a plurality of inorganic fiber mats having ears extending from the moisture-proof layer on both sides are folded in two and compressed in a laminated state in a packaging bag. In the packaging structure of the inorganic fiber mat, the inorganic fiber mat is folded with the moisture-proof layer side facing inward.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings.

In the present invention, when a plurality of glass fiber mats 1 are folded in two and compressed and packed in a packaging bag in a laminated state, as shown in FIG. It is folded with the faces facing each other. In other words,
The outer cover material 4 is folded outward. An adhesive 7 is partially applied on one surface of the moisture-proof layer 3 near the center of the end. The adhesive 7 temporarily adheres the moisture-proof layers 3 of the folded glass fiber mat 1 to each other and maintains the folded state during compression packaging. However, since the adhesive 7 is used only for temporary adhesion, it is preferable that the adhesive 7 has an adhesive force so that the moistureproof layer 3 is not broken when it is spread during construction. Then, a plurality of the glass fiber mats 1 folded as described above and temporarily adhered with the adhesive 7 are laminated and compressed in a packaging bag.

The specifications of the glass fiber of the glass fiber mat 1 used in the present invention are as follows.

Mat density 5-40 Kg / m ³ Mat thickness 20-200 mm Glass fiber Fiber diameter 4-15 μm Short fiber Binder type Phenol-based or urea-based Binder amount 2-25 wt% Glass fiber mat 1 with the above packaging structure is constructed At times, it is treated as follows.

Glass fiber mat 1 when it is taken out from the packaging bag
Has its moisture-proof layer 3 folded inward and has an adhesive 7
The moisture-proof layers 3 are temporarily attached to each other.

First, when the glass fiber mat 1 is directed to the studs 8 with the folded-back part facing up in the folded state,
The side is necessarily turned to the outdoor side. In this state, the glass fiber mat 1 is inserted between the studs 8 from below. Therefore, unlike the conventional example in which the moisture-proof layer 3 is folded outward, it is not necessary to unfold the glass fiber mat 1 and direct the outer covering material 4 to the outdoor side (the moisture-proof layer 3 to the indoor side).

Now that the ears 5 are on the studs 8, the lower ears 5
From there, stop with a gun tacker and so on. Since the glass fiber mat 1 is still folded in this state, it does not bend from the upper side during the fixing work, and the workability is improved.

Then, when the fastening reaches the vicinity of the folded-back portion, the temporary adhesion is released, the glass fiber mat 1 is expanded to the upper side of the stud 8, and the ears 5 thereof are sequentially fastened to the stud 8. The mat 1 is installed smoothly. Further, the workability is similarly improved in the fixing work from the ceiling.

Further, since the glass fiber mat 1 is folded with the moisture-proof layer 3 side inside, that is, since the outer covering material 4 is outside, the small holes 6 for deaeration are also located outside,
It is never blocked. Therefore, the glass fiber mat 1 is sufficiently degassed by the compression, and the compressed packaging becomes easy.

The glass fiber mat 1 in the above embodiment is an example of an inorganic fiber mat, and, for example, rock wool or the like can be applied.

[Advantage of Invention] As described above, according to the present invention, since the inorganic fiber mat is folded with the moisture-proof layer side inward when compressed and packed, the covering material is not covered during the construction. It is not necessary to unfold it to the outside, and it is possible to fix it to the stud while it is folded. Therefore,
Work efficiency and workability are significantly improved. Further, since the small holes for deaeration do not come out and are closed, it becomes easy to carry out compression packing in the packing bag.
