Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention comprises a building, a structure, or an existing outer wall with a dry panel, and has heat insulating property, fireproof property, waterproof property, soundproof property, seismic resistance, wind pressure resistance, The present invention relates to a sandwich panel with improved workability and design. More specifically, it relates to a sandwich panel that facilitates mounting and positioning of a joint cover attachment.

[Conventional technology]

This kind of building, for example, a panel for forming the outer wall of a warehouse with a sandwich panel or the like, includes a siding material in which a plastic foam is integrally interposed between a metal thin plate having male and female type connection parts and kraft paper, and a plastic between metal plates. Sandwich panel that inserts this with a rugged part formed on the side wall in the longitudinal direction through a foam, or heavy
Ceramic siding, which mainly consists of ALC siding, cement, calcium silicate, etc., is known.

[Problems to be solved by the invention]

However, the conventional metal siding material has a structure in which a synthetic resin foam is integrally interposed between a surface material and a sheet-shaped material such as kraft paper, and has a male-female connection structure, and a structure in which only one end is fixed, If the makeup width is about 400 mm and the thickness is about 25 mm or more, there are drawbacks that the siding material is likely to come off, the makeup surface has a mountain shape, and it is difficult to insert and insert the male and female connection parts. In addition, the sandwich panel lacks aesthetics due to the structure hit by the brain through the bolts,
Moreover, there was a disadvantage that it had to be constructed with a crane or the like. Of course, ALC siding and ceramic siding materials are heavy, have a limited decorative surface and thickness, are difficult to apply, and have the drawback of being vulnerable to freezing. Furthermore, both ends in the longitudinal direction of this type of panel are simply left uncut, and the treatment between the ends in the longitudinal direction often fills a joint material such as caulking material or packing material between joints, The cost was high, and the aesthetic appearance was deteriorated due to the difference in technology among the builders.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention has a rectangular or rectangular decorative surface, a side wall in which four edges of the decorative surface are bent downward, and a protrusion in which a lower end edge of the side wall is bent outward to extend. Piece, a surface material having a hat-shaped cross section formed from a guide surface in which an edge of the protruding piece is bent downward, a core material filled in the back surface of the surface material, and a back surface material covering at least the back surface of the core material. By installing the joint cover, the above problems can be eliminated and the heat insulation, fireproofness, waterproofness, soundproofing, earthquake resistance, wind pressure resistance, workability, and designability can be improved. (EN) Provided is a sandwich panel which facilitates the positioning of ingredients.
