Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a glass fiber mat lined with a metal folding structure used for a roof material or a wall material of a building. Metal plates having a folded structure are generally used as auxiliary materials for roofs, ceilings, floors, walls of building structures, vehicles, ships, etc., and their interiors and exteriors. In recent years, from the viewpoints of air conditioning, energy saving, and environmental protection of structures, the demand for various properties such as heat insulation, nonflammability, corrosion resistance, dewproofness, and soundproofing has also increased for those auxiliary materials. Also, in this case, there is an increasing number of cases in which a blanket made of a resin foam or a felt-like material is lined to satisfy these demands.

[0002] Conventionally, as a blanket backing a folded plate metal plate, urethane foam mats and polyethylene homes have been widely used because they are light and have good workability and excellent heat insulation, but they are gradually used because they are flammable. Are limited. Therefore, inorganic fibers such as asbestos, rock wool and glass fibers have come to be often used as non-combustible materials. On the other hand, as a method of sticking these blankets to a metal plate having a fold plate structure, a flat metal and a blanket are previously bonded with an adhesive, and then this is fold-repressed with a forming roll to form a backing fold plate. There are two methods: a so-called pre-attachment construction method for forming a structure and a post-attachment construction method in which a blanket dimensioned to a folded metal plate that has been previously folded is adhered later.

[0003] The pre-attachment method is excellent in continuous factory production and local workability, but a blanket made of inorganic fiber is liable to be broken due to poor flexibility of the fiber itself, and there is no restorability in a portion compressed by a forming roll. There was a defect that the thickness could not be obtained, and the heat insulating property and the dew condensation property of the structure were deteriorated and dust was easily generated. In this respect, the retrofitting method eliminates such drawbacks, but has a drawback of low workability because it is a construction method of cutting and adhering on site. Therefore, it has been proposed to cover one or both sides of an inorganic fiber mat with an organic non-woven fabric or film (JP-A-57-7889, JP-B-58-10227).
However, none of them are satisfied with respect to the letterpress processing in terms of material breakage and restorability, and the latter is also insufficient in nonflammability.

[0004]

Recently, attention has been paid to a so-called goby tightening method as a boltless method for shortening on-site construction time as a construction method for a metal folding structure, especially a folding roof. In this goby tightening method, even when a blanket in which one or both sides of an inorganic fiber mat is coated with an organic nonwoven fabric or a film is adhered, the nonflammability is still insufficient, and its improvement has been demanded. The present inventors, for example, in the so-called goby tightening method, as a result of diligent research and study on a method of performing a non-combustible metal folding structure with a method excellent in on-site construction, as a result, a glass fiber that solves the conventional defects The present invention has been completed by finding a method for constructing a mat.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a method for backing and adhering a glass fiber mat, one or both sides of which is bonded with glass paper and / or glass cloth, to a metal folding structure by backing and bonding. Alternatively, it is a method of constructing a glass fiber mat, characterized in that a lower end portion attached with a glass cloth is exposed, and the exposed end portion is sandwiched between the connecting portions of the metal folding structure to reinforce.

According to the method of the present invention, it is possible to reinforce by squeezing out the lower end portion of glass paper and / or glass cloth, and inserting the protruding end portion into the connecting portion of the metal folding structure. And various thicknesses, especially 10-
It has been found that even a 25 mm thick glass fiber mat can be easily applied, has excellent reinforcing properties, and significantly improves incombustibility. An object of the present invention is to provide a blanket for a metal lithographic structure, which has excellent properties such as non-combustibility, heat insulation, sound absorption, and dew resistance, does not cause material damage during lithographic processing, and has excellent restoration properties. It is to provide as a construction method with excellent workability on site.

Hereinafter, the method of the present invention will be described in more detail with reference to the drawings. FIG. 1 represents a schematic cross-section in the longitudinal direction of a glass fiber mat. In the figure, 1 is a glass fiber mat body, and A is a notch groove for folding the glass fiber mat 1. The size of the glass fiber mat is usually 1 to several meters in length and 0.5 m to several meters in width. Here, as the glass fiber mat used in the present invention, a mat formed by laminating glass fibers (long fibers or preferably short fibers) is used.
Needle punching and resin treatment are carried out if necessary, and the thickness thereof is not particularly limited, but 2-3
A thick one having a thickness of 0 mm, preferably 10 to 25 mm is preferably used.

The density of the glass fiber mat used in the present invention is not particularly limited, but is usually 32 kg / m ³ -4.
8 kg / m ³ is used. FIG. 2 is a schematic cross-sectional view showing a state where glass paper (2 in the figure) is attached to one surface of the glass fiber mat. Here, the glass paper refers to a sheet-like material such as a nonwoven fabric formed of glass fibers.

FIG. 3 is a schematic cross-sectional view showing a state in which a glass paper 2 is bonded to one surface of a glass fiber mat and a glass cloth (3 in the drawing) is bonded to the other surface of the glass fiber mat. M) indicates the edge of the ear. Here, the glass cloth refers to weaving, knitting or the like formed of glass fibers. One or both sides of the glass paper and / or the glass cloth are attached for the purpose of reinforcing the glass fiber mat and shaping and holding. Here, as shown in FIG. 3, it is necessary to expose the lower end of one or both sides of glass paper and / or glass cloth stuck in the longitudinal direction. The width of the protruding end is the same as that of the glass fiber mat, and its length (h in FIG. 3) is not particularly limited, but is usually 10 to 100 mm, preferably 25 to 80.

In the figure, 6 is a tight frame for reinforcing (supporting) the metal folding structure, and 5 is a suspender for fixing the tight frame 6. The suspension is fitted in the connection portion of the metal folding structure.

FIG. 6 is a schematic cross-sectional view showing a state in which the connection portion of the metal folding structure is narrowed down. It shows a state in which it is tightened by the so-called goby tightening method. FIG. 7 is a schematic view showing a continuous state of being tightened by this goby tightening method. As shown in the drawings, the present inventors have found that an excellent construction can be performed by pasting a glass cloth on one side of a glass fiber mat and pasting a glass paper on the other side and exposing the end of the glass cloth. .

In the present invention, the edge-out end portion is sandwiched between the connection portions of the metal folding structure, and specifically, in the goby tightening method, the edge-out edge portion is sandwiched at the same time. It is done by tightening. Further, the sandwiching is not limited to goose tightening, and for example, a groove is provided in the longitudinal direction at an intermediate portion in the lateral direction of the metal folding structure, and an appropriate inclusion such as a columnar glass mat is provided in the groove. Similar objectives can be achieved by packing.

[0013]

According to the method of the present invention, even a glass fiber mat having various thicknesses, particularly a thickness of 10 to 25 mm, can be easily applied, and the reinforcing property is excellent and, for example, the nonflammability is remarkably improved. Thus, a blanket for metal fold structure that has excellent properties such as non-combustibility, heat insulation, sound absorption, and dew resistance, does not cause material breakage during lithographic processing, and has excellent resilience is used for on-site workability. It can be provided as an excellent construction method.
