BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite fireproof panel in which a metal panel is adhered to the front side of a fireproof panel made of a fireproof material.

[0002]

2. Description of the Related Art Recently, as a composite fireproof panel for an outer wall of a building, an enamel panel having excellent appearance and durability has been widely used as a top panel. However, enamel panels are limited in size because of the equipment for enamel glazing and firing, and large panels cannot be manufactured. For this reason, when the building wall is composed of a composite fireproof panel with the enamel panel as the top plate,
It is necessary to fix a grid-like base material close to the panel size to the building frame, and screw a number of clips fixed to the bent pieces of many enamel panels to the base material,
It required a scaffolding and a lot of manpower and construction time.

[0003] In order to improve this point, a plurality of enamel panels are arranged on a large-sized concrete plate and both are mainly joined by an adhesive, and the plurality of enamel panels are arranged with the back side up. There has been proposed a structure in which the surroundings are surrounded by a mold, and mortar is poured to be solidified and integrated.

However, in each case, since the firing distortion of the enamel panel is hardly corrected, there is a problem that unevenness of the surface of each enamel panel is conspicuous and only an inferior appearance is obtained. In addition, in the case of using an adhesive for bonding the enamel panel and the concrete plate, there is a great risk of peeling and falling off due to the deterioration of the adhesive, and even if an attempt is made to use the concrete nail together, the driving of the concrete nail is special. Equipment is required and work is also troublesome.

In the case of the mortar pouring type, in order to securely connect the enamel panel to the fireproof panel, a reinforcing bar embedded in the fireproof panel and a bent piece of the enamel panel are connected by welding or the like, or the main plate is welded. There has been a method of welding a T-shaped or L-shaped cross-section to the part, but the former requires a complicated preparation process before pouring, and the latter causes distortion on the surface of the main plate due to welding, which significantly reduces the appearance. There was a problem.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and provides a composite fire-resistant panel having an excellent appearance, which can easily and surely join a metal panel and a fire-resistant panel. What you want to do.

[0007]

According to the composite fireproof panel of the present invention, a piece-shaped anchor member is fixed to the bent piece portion of a metal panel having a bent piece portion connected to four circumferences of a main plate portion. A backing material is adhered to the back surface of the main plate portion, and a slurry mainly composed of an inorganic material is poured and solidified into a back space portion of the metal panel to which the backing material is adhered.

In the present invention, as the metal panel, those obtained by surface-treating panels of various metal materials can be used. In particular, various types of metal panels such as steel plate, stainless steel plate, aluminum-plated steel plate, aluminum-plated stainless steel plate, aluminum plate and the like can be used. If a metal plate is used as the base material and an enamel panel is provided with an enamel layer on at least the surface side, or a baked paint panel with at least the surface side baked is used, the warpage of the main plate portion that tends to occur on these panels This is preferable because unevenness and unevenness can be effectively corrected by bonding the backing material.

In the present invention, examples of the backing material include a calcium silicate plate, a gypsum board, and a flexible board.
Various heat-insulating boards such as a heat-insulating board and a honeycomb sheet such as an aluminum honeycomb can be used, but it is particularly preferable to use a heat-insulating board. The adhesion between the backing material and the main plate of the metal panel is 0.5 to ⁵ kg / cm ^{2 in} surface pressure.
Pressure bonding.

In the present invention, the slurry mainly composed of an inorganic material includes mortar, mortar to which aluminum powder is added as a foaming agent, mixture of mortar and wood wool, mixture of mortar and asbestos, and various refractory materials such as gypsum. Slurry obtained by adding water to the panel material is used. In addition, it is more preferable to add inorganic fibers such as glass fiber, metal fiber, and carbon fiber to the refractory panel raw material because the strength is improved.
It is more preferable to add inorganic particles having bubbles, such as porous vermiculite, perlite, or hollow shirasu balloon, to the above-mentioned raw material for a refractory panel, because the heat insulating property is improved and the weight is reduced.

[0011]

In the composite fireproof panel of the present invention, the backing material adhered to the main plate portion of the metal panel corrects the warpage and irregularities of the main plate portion and improves the appearance. When a heat insulating board is used as the backing material, the heat insulating property of the composite fireproof panel is improved.

The slurry poured into the back space of the metal panel and solidified forms a refractory panel, and the piece-shaped anchor member is embedded in the refractory panel, and is bent with the refractory panel. Securely connect the pieces. Since the anchor member is fixed to the bent piece portion, even when the anchor member is fixed by welding or the like, welding distortion does not reach the main plate portion, and the excellent appearance of the metal panel is maintained.
