JPH06219813A - Foamed body press-bonded stone composite panel - Google Patents

Abstract

PURPOSE:To obtain the composite panel of highly reliable structure by press- bonding a stone panel, a fastener plate and a fastener mounting embedded metal utilizing the volume expansion pressure of a foaming body of concrete and resin. CONSTITUTION:For example, a stone panel 3 is laid in a lower framework 5, aerated concrete 2 is then injected, and finally a fastener plate also used as a framework or an upper framework 6 is joined to the lower framework 5 with a bolt 7 and closed. A fastener mounting embedded metal 4 is embedded as such or previously fixed to the fastener plate 6 and integrated. The aerated concrete 2 is foamed to generate a volume expansion pressure, high pressure- cured, hardened and then released from the mold. Consequently, the fastener plate 6 on the rear of the panel 3 and the embedded metal 4 are press-bonded by themselves and integrated, and the desired composite panel is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone panel for interior and exterior of a building and a stone-clad construction method.

[0002]

2. Description of the Related Art As a conventional general stone composite panel, there is a resin adhesive composite panel.

The resin-based adhesive composite panel is a stone panel in which a metal panel and a glass fiber are adhered and reinforced by an epoxy resin or the like.

[0004]

However, the above-mentioned prior art has the following problems.

The durability and weather resistance of the resin adhesive itself used for the permanent structure has not been sufficiently proven, and the material properties of stone, resin and metal are greatly different, so the strength and durability of the adhesive interface are high. And weather resistance, structural stability,
Unreliable.

Since the metal panel and the glass fiber do not have a fastener function, it is necessary to form a hole in the stone separately for the fastener to be embedded or to be resin-based adhesive, which is troublesome and structurally low in reliability.

[0007]

DISCLOSURE OF THE INVENTION The present invention solves the above problems by developing a foam pressure-bonded stone composite panel.

[0008]

EXAMPLE An example of the foam pressure-bonded stone composite panel according to the present invention will now be described with reference to FIGS.

FIG. 1 shows a cross-sectional view of a foam-compression-bonded stone composite panel according to the present invention during manufacture. The stone panel 3 is laid in the lower formwork 5, then the foam concrete 2 is poured, and finally the fastener plate also serving as the formwork or the upper formwork 6 is joined to the lower formwork 5 with the fixing bolts 7 and hermetically sealed. The fastener mounting hardware 4 may be arranged and embedded as a single body, or may be preliminarily attached to and integrated with the fastener plate 6 that also serves as a frame. After foaming and curing, the mold is removed and the manufacturing is completed.

FIG. 2 shows a detailed cross-sectional view of a foam pressure-bonded stone composite panel according to the present invention. The molded foam pressure-bonded stone composite panel 1 has a structure of a stone panel 3, foam concrete 2, a fastener mounting embedded metal 4 and a fastener plate 6 from the surface.

[0011]

The foam pressure-bonded stone composite panel according to the present invention has the following unique effects.

Generally, foamed concrete having stable strength is carried into a high-pressure pot for high-pressure curing at the time of production in order to ensure its performance. In the present invention, by foaming the foam in a hermetically closed state, it is possible to internally generate a foaming expansion pressure and perform high-pressure curing with the same effect as a high-pressure pot.

Since the stone panel, the fastener plate and the like and the foam are simultaneously molded with high adhesive strength without using an adhesive due to foaming expansion pressure, a composite panel having high structural reliability can be obtained.

By selecting the pre-attached fastener plate and the post-attached fastener plate, it is possible to select the construction method suitable for the base skeleton of all kinds of materials.

By using a mixture of an acrylic modified polymer solution or the like as the concrete foam,
Further, it is possible to increase the adhesive strength and the like.

It is possible to obtain the composite performance such as the heat insulating effect, the fire resistance performance and the sound insulation performance that the foam has.

Since it is lightweight and has high strength, the workability is remarkably improved.

The economic efficiency is improved.
