How to install ALC panel on concrete slab in longitudinal direction {Method for installing ALC panel to concrete slab}

The present invention relates to a method of installing an ALC panel in a concrete slab in a longitudinal direction in a curtain wall system using an ALC panel.

The exterior walls of high-rise buildings in Korea are mostly made of curtain walls, which can reduce manpower, and are classified into metal panel type and PC panel type.

Metal panel type raises the energy load of the building due to the lower thermal insulation due to high thermal conductivity, and installs the insulating material of organic and inorganic system between the sphere and the curtain wall. Phenomenon occurs. In addition, there is a weak fire resistance in the case of fire.

In the case of PC (Precast Concrete) panel type, the advantage is that the panel can be manufactured with the insulation material, window frame, tile, etc. in one factory, so that high quality curtain wall is possible and fire resistance is excellent in the fire. It is big.

When replacing PC panels with ALC (Autoclaved Light-weight Concrete) panels, curtain walls can be lightened and high-load problems can be solved. In addition, fire resistance and fire resistance can be ensured and the energy load of the building can be reduced by improving the insulation.

However, when the ALC panel is replaced with a curtain wall member, it is difficult to apply due to the low strength and brittleness of the ALC panel. There are ways to solve the low strength and brittleness of the ALC panel, but there is a method to strengthen and reinforce the ALC panel. However, the strength of the ALC panel is limited. Therefore, cracks, fractures and deformations of the ALC panel due to wind pressure at the junction between the sphere and the ALC panel are prevented. It needs to be relaxed.

An object of the present invention is to provide a method for constructing an ALC panel that can safely and reliably transmit the external wind load received by the ALC panel to a sphere in applying the ALC panel to a curtain wall system.
