The fire resitant material 3 is laminated between almost waveform two folded-plate materials 2 continuing in a crest part and a trough part in a state of being brought into close contact with an inside surface of the respective folded-plate materials 2, and at least one of these two folded-plate materials 2 is used as a folded-plate material 2 having a large crest height to constitute the folded-plate for a wall.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folded plate used for an outer wall or an inner wall of a building requiring a fire-resistant structure.

[0002]

2. Description of the Related Art A refractory material such as a gypsum board, a rock wool board, a calcium silicate board or the like is conventionally used in a metal drywall method for a building requiring a fireproof structure.
As a method of fixing these refractory materials to the building, a rim (C-shaped steel) is provided between the studs of the building at a pitch of about 450 mm to 900 mm, and a single piece of the refractory material having a specially treated joint is provided on the rim. A dry method is generally used in which an exterior material or an interior material is applied to the outer and inner surfaces of the refractory material after the application (or the overlapping application).

[0003] Other fire-resistant wall materials include a steel-plated fire-resistant sandwich panel, a single-sided steel plate flat panel, and the like. These fire-resistant wall materials are also provided with bolts, nuts, or nuts on a trunk provided between studs of a building. A method of fixing with tapping screws or the like is adopted.

[0004]

When a fire-resistant wall is constructed using a fire-resistant material such as a gypsum board or a rock wool board, the exterior material or the interior material is constructed after the fire-resistant material is attached to the rim. Because of the necessity, the man-hours and construction man-hours for material management on site are inevitably increased. Moreover, since the refractory material such as a gypsum board has a low strength, as described above, the rim is provided and the support span is set to 450 mm to 90 mm.
It is necessary to set it to 0 mm, which requires extra man-hours and cost for installation of the rim, and the support span is short, so it takes a lot of man-hours to stick fireproof materials and exterior / interior materials. There is a problem that it becomes longer.

On the other hand, steel fire-resistant sandwich panels are shipped from a manufacturing plant as products having a fire-resistant structure, so that the number of construction steps on site is reduced as compared with a method using a gypsum board or the like. The type of refractory wall material is also not excellent in strength, and the supporting span is set to 900 mm ~
It is necessary to be 1500 mm, and many man-hours are required for attaching the panel. In addition, there is also a problem that the product cost is high for the refractory sandwich panel made of a steel plate.

The present invention has been made in view of such circumstances, and is excellent in heat insulation and fire resistance and workability, and can be used for a long span without a rim, and is economical for a folded plate for a wall. For the purpose of providing.

[0007]

In order to achieve the above object, a folded plate for a wall according to the present invention is a substantially corrugated member having a continuous peak portion and a valley portion, and a refractory material is provided on one surface of a folded plate material having a large peak height. It is characterized by being stacked in close contact.

Further, in the folded plate for a wall according to the present invention, a refractory material is laminated between two substantially folded folded plate materials having continuous peaks and valleys in a state of being in intimate contact with the inner surface of each folded plate. In addition, at least one of the two folded plate members is characterized by being constituted by a folded plate member having a large mountain height.

The term "folded plate material having a large mountain height" as used in the present invention refers to a folded plate material having a height (mountain height) from the bottom of the valley to the top of the mountain of the folded plate of 80 mm or more.

According to the wall folded plate of the present invention, the rigidity is strengthened by using a folded plate material having a large mountain height as a main member, so that a dry construction method using a flat gypsum board or the like, or a panel-type fire-resistant plate is used. The support span can be made larger than the construction method using the wall material, and the construction without the rim can be performed. Furthermore, since the refractory material is adhered to the folded plate material at the factory in advance,
In addition to stabilizing quality such as fire resistance, the number of man-hours at the construction site can be reduced and the construction period can be shortened. In addition, since the folded plates for walls can be stored and transported by being superimposed on each other, the stackability is good, and space saving during storage and transport can be achieved.

The refractory material used for the folded plate of the present invention may be a single material or a composite material obtained by mixing and laminating a plurality of types of materials.

In the folded wall plate of the present invention, when adopting a configuration in which a refractory material is laminated on one side of the folded plate material, if a heat insulating material such as glass wool is laminated on the refractory material, the fire resistance performance is further improved. In addition, heat insulation, sound absorption and sound insulation are improved.

The folded sheet material used for the folded sheet for a wall according to the present invention includes a coated steel sheet, a hot-dip galvanized steel sheet, a stainless steel sheet,
Alternatively, an aluminum plate or the like can be used. The thickness of the folded plate material is not particularly limited, but when a steel plate is used, for example, 0.6 mm to 1.2 mm is appropriate.

Examples of the refractory material used for the wall folded plate of the present invention include refractory paint refractory materials such as plaster, cement, rock wool, and expandable graphite-added paint, and sheet-like refractory materials. Can be

Examples of the gypsum system include wet gypsum laminated on a folded plate at a factory, gypsum board processed into a folded plate shape, and the like.

Examples of the rock wool type include a rock wool mat, a rock wool board processed into a folded plate shape, and the like.

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

FIG. 1 is a sectional view schematically showing an embodiment of a folded plate for a wall according to the present invention. The folded plate material 2 is a member obtained by processing a 0.8 mm thick painted steel plate into a waveform in which trapezoidal peaks and valleys are continuous. The pitch of the crests (valleys) of the folded plate material 2 is 250 mm, and the crests (valleys) are spaced from the bottoms 2b to the tops 2c.
The height up to a (mountain height: H) is 150 mm.

On one side of the folded plate material 2, a refractory material 3 having a uniform thickness is laminated in close contact. The refractory material 3 is obtained by spraying a refractory paint to which thermally expandable graphite is added.

A heat insulating material 4 is laminated on the surface of the refractory material 3. The heat insulating material 4 is laminated for the purpose of improving fire resistance and adding heat insulation and sound absorption. In this example, a rock wool mat (density 65 kg / m ³ , thickness 50 m) is used.
m). Note that such a process of spraying the fireproof paint and laminating the heat insulating material is performed in the manufacturing factory, and the construction site includes a folded plate for a wall in which the fireproof material 3 and the heat insulating material 4 are laminated on one surface of the folded plate material 2. 1 is shipped as a product.

The above-mentioned on-site construction of the wall folded plate 1 is as follows.
For example, as shown in FIGS. 2 and 3, a tight frame 52 is provided on a stud 51 of a building (not shown), and the tight frame 52 is fixed to the tight frame 52 by using a tapping screw 53.

In such a construction method, when fixing the folded plate 1 for a wall to the tight frame 52, there is a concern that the heat insulating material 4 is interposed between the folded plate 2 and the tight frame 52 and becomes an obstacle. However, since the rock wool mat used for the heat insulating material 4 has a sufficient compressibility, there is no particular problem in attaching to the tight frame 52.

Further, in the construction examples shown in FIGS. 2 and 3, a construction method is employed in which both the crests and the valleys of the wall folded plate 1 are fixed by tapping screws 53, but there is no problem in strength. For example, a construction method of fixing only the valleys of the wall folded plate 1 may be adopted.

Here, when the folded wall plate 1 shown in FIG. 1 is attached between the studs 51 of the building by the method shown in FIGS. 2 and 3, sufficient strength can be obtained even when the supporting span is 4500 mm. It could be confirmed.

FIG. 4 is a sectional view schematically showing another embodiment of the present invention. The wall folded plate 11 shown in FIG.
A rock wool mat (density of 85 k) was used as a fireproof material 13 on one side of a folded plate material 2 having the same material and shape as those shown in FIG.
g / m ³ , and a thickness of 50 mm), and even when a single-layer refractory material 13 is formed,
Sufficient strength and fire resistance can be obtained.

When a fire-resistant adhesive such as a sodium silicate-based adhesive is used as the adhesive in the wall folded plate 11 shown in FIG. 4, the fire resistance of the wall folded plate 11 can be further improved.

The folded wall plate 11 shown in FIG. 4 can be constructed by the same method as the method shown in FIGS.

FIG. 5 is a cross-sectional view schematically showing another embodiment of the present invention. The wall folded plate 21 shown in FIG.
Folded plate material 22 obtained by processing a painted steel plate of 8 mm into a waveform in which trapezoidal peaks and valleys are continuous, folded plate material 24 of a 0.5 mm thick painted steel plate also processed into a corrugated shape, and two folded plate materials thereof It is constituted by a refractory material 23 laminated between 22 and 24.

This wall folded plate 21 is formed by bonding a rock wool mat (density: 85 kg / m ³ , thickness: 50 mm) as a fireproof material 23 to the inner surface of a folded plate material 22 serving as an exterior material. Is manufactured by bonding a folded plate material 24 serving as an interior material.

The pitch and the height of the peaks (valleys) of the folded plates 22 and 24 are the same as those in the previous embodiment.
50 mm, mountain height: 150 mm. Further, a spacer 25 is provided between the folded plate member 22 and the folded plate member 24 to secure an interval therebetween.

In the on-site construction of the wall folded plate 21, for example, as shown in FIG. 6, a hole 22a for tool insertion is formed in the outer folded plate material 22, and a tapping screw 53 is inserted through the hole 22a. Inside folded plate 24 and tight frame 5
2 and the wall folded plate 21 is fixed to the stud 51. Note that the tool insertion hole 22a is closed with a cosmetic cap or a cosmetic bolt / nut after the mounting operation is completed.

In the construction example shown in FIG.
Although the method of fixing both the crests and the valleys by tapping screws is employed, if there is no problem in strength, a method of fixing only the valleys of the wall folded plate 21 may be employed. .

Here, in each of the above-described embodiments, an example of a method of sticking so that the peaks (valleys) of the wall folded plates 1, 11, and 21 extend along the horizontal direction, that is, an example of so-called horizontal sticking is shown. Without being limited to this, the folded plate for a wall of the present invention can also be used when a wall is constructed by vertical application.

In each of the above-described embodiments, a folded plate material having a trapezoidal peak and valley is used. However, the present invention is not limited to this. For example, a circular or rectangular peak or valley may be used. A folded plate material of another arbitrary shape such as a waveform having continuous valleys may be used. However, the height of the folded plate material is 80 mm or more.

[0035]

As described above, according to the wall folded plate of the present invention, since the rigidity is strengthened by using a substantially wave-shaped folded plate having a large mountain height for the main member, a gypsum board or the like is used. Compared with the dry method or the method using a panel type fire-resistant wall material, the support span can be increased, and the construction without the rim can be performed.

Therefore, by using the wall folded plate of the present invention, for example, the outer wall or the inner wall of a large-scale store, an amenity hall, a warehouse or the like that requires a fire-resistant structure and air conditioning can be finished in a short construction period. Significant cost savings can be achieved.
