Abstract

PROBLEM TO BE SOLVED: To make improvements in the fire resistance and fire preventability of a connecting part by filling up a fire-proof filler, being made up of laminating a proof sheet on a platelike base material consisting of an inorganic material or high density synthetic resin material, in the connecting part of a building panel. SOLUTION: A building panel α is a composite plate having interposed a core 3 being high in fire protecting performance in space between a surface material 1 and a backside material 2 consisting of a noncombustible steel sheet, and a filler A is indwelt in both male and female connecting parts 4 and 5 formed in the ends. This filler A is one that laminated a fire proof sheet being made up of binding a graphite ingredient and an inorganic fiber to a fire-proof platelike base material consisting of an inorganic material or high density synthetic resin material with phenolic resin, and it is formed in accord with each form of these connecting parts 4 and 5. In addition, inorganic system packing 6 is interposed in the male connecting part 4, and soft packing 7 is interposed in the female connecting part 5 as well. With this constitution, the filler A is situated at both upper and lower sides of the connecting part and thereby fire resistance, fire protectability and further waterproofness in the connecting parts are all improvable.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof filler for building panels requiring fireproof performance and fireproof performance, and more particularly to a panel connecting portion which is regarded as a weak point of fireproof performance and fireproof performance. To dramatically improve fire protection and fire resistance.

[0002]

2. Description of the Related Art In general, as a current construction panel, a panel in which a core material is sandwiched between a front material and a back material using a nonflammable steel plate is put on the market.

[0003]

However, a panel having such a structure is deformed in a greatly different direction by being pulled toward a heating side due to a difference in heat conduction under a high heat. A gap is formed in the connection part, heat and flame leak from this part to the opposite side and JIS
There was a defect that the fireproof structure 1-hour test (the fireproof structure test of 30 minutes, 1 hour, and 2 hours) of A-1304 could not be passed.

Further, when the core material is formed of a synthetic resin foam such as phenol foam or an inorganic fiber such as rock wool or glass wool, a panel is formed at a connecting portion which is a weak point of fire prevention performance and fire resistance performance. When exposed to a high temperature, the core material becomes thin and voids are formed, and the flames or high heat reach the opposite side of the panel from the voids, causing a fire.

[0005]

According to the present invention, at least one layer of a refractory sheet is laminated on a plate-like substrate mainly made of an inorganic material or a high-density synthetic resin material in order to eliminate such disadvantages. The refractory sheet proposes a refractory filler for panels formed by binding at least a graphite component and an inorganic fiber with a synthetic resin, and by filling this filler into a connecting portion of a building panel, a conventional refractory sheet is formed. Even in the connection part which has been regarded as a weak point part of fire prevention and fire resistance, it is possible to provide a panel having excellent fire resistance and fire resistance.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a refractory filler A for a panel according to the present invention. FIG. 1 is a partially cutaway perspective view showing a typical example of the filler A. The filler A is formed by laminating at least one or more refractory sheets C on a plate-shaped base material B.

[0007] The plate-shaped substrate B has fire resistance,
It is a long plate-like material of any thickness made of an inorganic material or a high-density synthetic resin material as a main raw material. That is, examples of the inorganic material include a calcium silicate plate, a calcium carbonate plate, a gypsum board, a pearlite cement plate, a rock wool plate, a slate plate, an ALC plate, a PC plate, other inorganic lightweight bodies, and inorganic lightweight foams. Body or one of these composite boards
Consists of more than species.

Further, as an example of the case of using a high-density synthetic resin material, a highly incombustible phenol resin is used for about 250 to 3 parts.
It was finished at a high density of 50 kg / m ³ . Of course,
Flame-retardant materials such as aluminum hydroxide powder, ammonium polyphosphate powder, calcium carbonate powder and the like can also be mixed therein. Further, the plate-shaped base material B may be a composite material of an inorganic material and a high-density synthetic resin material.

The refractory sheet C is formed on the plate-like base material B by one or more layers via a separate adhesive (not shown) or the refractory sheet C
It is a long sheet-like material having a total thickness of about 0.5 to 10 mm, which is integrally laminated by heat fusion of its own resin.

Further, the composition of the refractory sheet C comprises a graphite component and an inorganic fiber bound with a phenol resin. The graphite component is made of, for example, a carbon compound such as graphite (expandable or non-expandable) or carbon black, and when heated, carbonizes to form a heat insulating layer and hinder heat conduction. The graphite component accounts for about 50 to 80% of the weight ratio of the entire refractory sheet C.

Examples of the inorganic fibers include a heat-resistant inorganic compound such as glass fiber, ceramic fiber, rock wool, and asbestos. It has the function of giving flexibility (handling). The inorganic fibers occupy about 5% to 20% of the total weight.

The phenol resin functions as a binder between the graphite component and the inorganic fiber, and has high fire resistance and fire resistance. Further, by binding the graphite component and the inorganic fiber with a synthetic resin phenol resin, the refractory sheet C has flexibility,
Plasticity and elasticity are taken into account, and the refractory sheet C can be easily wound up or formed into a coil shape and is very easy to handle. The phenolic resin accounts for about 10% to 30% of the total weight.
Occupy.

FIG. 2 is a partially cutaway perspective view showing the building panel α in which the filler A is actually filled in the connecting portion. The construction panel α is composed of a front material 1 and a back material 2 made of a noncombustible steel plate.
Thus, it is composed of a long plate-shaped composite plate in which a core material 3 having high fire-proof performance such as phenol foam, rock wool, glass wool, ceramic wool, inorganic foam plate or the like is sandwiched.

At the end of the architectural panel α, a male connecting portion 4 and a female connecting portion 5 each having an arbitrary shape are formed, and a filler A is embedded in each of these connecting portions. Things. The filler A is arbitrarily excavated, cut, or the like so as to conform to the shape of each connecting portion, and the shape is adjusted to be integrally filled.

In this way, the filler A is located just above and below the connecting portion where the male connecting portion 4 and the female connecting portion 5 of the building panel α are engaged with each other. It is possible to greatly improve the fire prevention performance and the fire resistance performance of the connection part, which is a weak point of the fire prevention performance and the fire resistance performance, and also to improve the mechanical strength of the connection part. Moreover, even if the core material 3 of the connecting portion is thinned due to exposure to high heat, the refractory sheet C can be foamed and carbonized to fill the thinned portion and form a heat insulating layer.

In this construction panel α, an inorganic gasket 6 is interposed between the male connecting portion 4 to further improve the fire prevention performance and fire resistance of the connecting portion, and the female connecting portion 5 is provided.
Is provided with a single piece of soft packing to ensure waterproofness.
