Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sandwich panel useful for constructing the outer wall of a building or structure using dry panels. More specifically, the present invention relates to a sand inch panel that facilitates the installation and positioning of a joint cover fixture and that does not create a space on the back surface of the sand inch panel even when a batten board is installed between the joints.

[Prior Art] As a panel for forming the outer wall of this type of building, for example, a warehouse using a sandwich panel, etc., there are Δ, a siding material in which a plastic foam is integrally interposed between a thin metal plate having a female connection part and kraft paper; Sand inch panels, in which plastic foam is interposed between metal plates and uneven parts are formed on the side walls in the long plane direction, and these are inserted, are manufactured using ceramics mainly made of heavy ALC siding, cement, calcium silicate, etc. System siding is known.

[Problem to be solved by the invention]

However, conventional metal siding materials have a synthetic resin foam interposed between the surface material and a sheet-like material such as kraft paper, and have a male-female connection structure, with only one end fixed. The makeup width is approximately 400m5.
When the thickness is about 25 mm or more, there are disadvantages in that the siding material tends to come off easily, the decorative surface becomes mountain-like, and it becomes difficult to insert the male and female type connecting parts. Furthermore, the sandwich panel has a structure in which bolts are used to form the panel, so it lacks aesthetic appeal and has the disadvantage of having to be constructed using a crane or the like. Of course, ALC siding and ceramic siding materials are heavy, have limited decorative surfaces and thickness, are difficult to install, and have the drawbacks of being susceptible to freezing and thawing. Furthermore, in order to improve the waterproofness, fireproofing, and workability of the joints of this type of sandwich panel, it has been considered to interpose an inverted T-shaped sill plate on the back side of the joint. This creates a space on the back side of the sand inch panel, resulting in poor earthquake resistance and strength against external forces, and deformation due to solar radiation.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention consists of front and back materials made of metal plates, and a heat insulating material made of lightweight plastic foam is integrally interposed between the two surfaces, and furthermore, on both sides of the decorative surface, It is fixed to the building frame via a protruding piece provided at a position covered by the joint cover during construction,
Both sides of the decorative surface in the longitudinal direction have the same structure, and the width of the decorative surface is 5.
00~900au, thickness 30~50aue, length 4~
The present invention provides a sandwich panel in which the width of the sandwich panel can be increased to 10 m, and cutouts are formed at both edges of the backing material to accommodate the fixing portions of the paving boards.
