Abstract

PURPOSE:To enhance fire resistant performance by integrating one type or at least two types of insulation materials, such as calcium acetate boards or cement extruded boards on the rear surface of a large-sized ceramic board under solid structure. CONSTITUTION:Three large-sized ceramic boards 1 of solid structure are lined up so that flat-surfaced plasterboards 2 are integrally laminated on the rear side of the large-sized ceramic boards 1. Then, a steel-made frame 3, which comprises a cross section L-shaped material assembled in a frame, is mounted on the side surfaces of the large-sized ceramic boards 1 and the ceramic boards 2 and fixed with bolts 4. It is, therefore, possible to enhance fire resistant insulation performance of the large-sized ceramic boards.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-bearing wall having a fireproof performance using a large porcelain plate.

[0002]

2. Description of the Related Art Large-scale porcelain plates used for the exterior of steel-framed constructions are building materials that are excellent in design and have good durability, and thus have the performance as non-bearing walls.
It can be used alone. Therefore, by applying the ceramic plate to the exterior of the building, it is possible to easily perform the exterior installation of the building with good design. The porcelain plate can be applied to the wall surface by adhering it to various structural materials with an organic adhesive or the like.

[0003]

Since a large porcelain plate is an inorganic substance, it does not burn, but since it is a thin substance, it has poor heat insulating properties, and it is easy to convey a temperature rise on the front face to the back face. Therefore, when a fire occurs, the temperature on the back side of the porcelain plate rises, and the combustible material on the back side burns.

Therefore, conventionally, it has been impossible to use a large porcelain plate alone in a place where fire resistance is required. In addition, when a large porcelain plate is constructed using an adhesive, there is a problem that it is peeled off by a fire and the organic adhesive is burned.

For these reasons, it has been desired in the past to develop a technique in which a large porcelain plate can be used as a non-bearing wall where fire resistance is required.

The present invention has been made in view of the above conventional circumstances, and an object thereof is to provide a non-bearing wall having fireproof performance using a large porcelain plate.

[0007]

The non-bearing wall of the present invention comprises a large porcelain plate having a solid structure, a calcium silicate plate, a cement extruded plate, a slate plate, rock wool board, sprayed rock wool, glass wool board, Fire resistance formed by combining and integrating one or more heat insulating materials selected from the group consisting of wood wool cement board, wood chip cement board, ALC board (autoclave-cured lightweight concrete board), slag gypsum board and gypsum board. It is characterized by having performance.

In the present invention, the large porcelain plate is 60
Such a large-sized porcelain plate having a solid structure of 0 mm × 250 mm or more is manufactured by a conventional method of molding and firing various raw materials such as clay. The cross-sectional shape, physical properties, material, thickness, etc. of this large porcelain plate are not particularly limited, but the thickness is generally 5 to 30 m.
It is about m.

The heat insulating material is usually 10 to 100, though it varies depending on the required heat insulating property.
A plurality of one or more sheets are laminated and used so as to have a thickness of about mm.

Any method may be used as a method for integrally combining a large porcelain board and a heat insulating material as long as it can be securely fixed. However, preferably, the method described below is performed without using an organic adhesive. As shown in the example, a method of bolting with a frame is preferable.

[0011]

The fireproof heat insulating performance of the large porcelain board can be improved by compositely integrating a heat insulating material having excellent fire resistance and heat resistance on the back side of the large porcelain board.

[0012]

EXAMPLES The present invention will be described more specifically with reference to Examples and Comparative Examples below.

Example 1 The cross-sectional shape shown in FIG. 2 has a length of 900 mm, a width of 300 mm,
Three large porcelain plates 1 having a thickness of 15 mm were arranged side by side, and a gypsum board 2 having a planar shape of 21 mm shown in FIG. 3 was integrated on the back side thereof. The large porcelain plate 1 and the gypsum board 2 were fixed according to the method shown in FIGS. 1 (a) (plan view) and (b) (cross-sectional view taken along the line BB in FIG. 1 (a)). That is, the iron frame 3 formed by assembling an angle member having an L-shaped cross section into a frame shape,
The laminated body of the large-sized porcelain board 1 and the gypsum board 2 was fixed to the laminated body by covering the four peripheral edges of the large-sized porcelain board 1 from the side surface and attaching the frame 3 to the side surface of the gypsum board 2 with a bolt 4.

Regarding the obtained structure, JIS A-1
When a fire resistance test was conducted in accordance with 304 (fire resistance test method for building structures), the backside temperature only increased to 245 ° C even after 1 hour from the start of heating, and it had fire resistance certification performance (1 hour fire resistance performance). Was confirmed.

Comparative Example 1 A large porcelain plate shown in FIG.
A fire resistance test was performed according to 04. As a result, it was found that the temperature of the back surface rose to 300 ° C. 10 minutes after the start of heating, and the fire resistance was not exhibited.

[0016]

As described in detail above, according to the non-bearing wall of the present invention, a non-bearing wall having a fireproof heat insulating property and capable of obtaining a fireproof certification is provided by using a large porcelain plate. For this reason,
According to the non-bearing wall of the present invention, it is possible to apply a large porcelain plate to a non-bearing wall that requires fireproof certification.
