Description

[Detailed description of the invention] The present invention relates to a lightweight construction panel, and more specifically, a rigid core material having a large number of penetrating cavities is used as the core material, and if necessary, the cavities of the core material are filled with foam material. The present invention relates to lightweight construction panels with sufficient strength and rigidity.

Conventionally, lightweight construction panels have been produced using paper honeycomb, plastic foam, glass wool, etc. as core materials, and FRP (Fiber Reinforced
Plastics), lightweight sandwich panels with surface materials such as vinyl chloride, steel plates, gypsum plates, asbestos-cement boards, plywood, etc., hollow extrusion panels made of inorganic hydraulic materials, and even ALC (Autoclaved
Aerated concrete products such as Light Weight Concrete) are used. However, the above-mentioned sandwich panel has low strength and rigidity, so it can only be used as a mounting wall, and inorganic hydraulic materials have limitations in reducing weight and are difficult to extrude. Furthermore, ALC has the disadvantage that the production process is complicated and the products are standardized.

Therefore, the present inventor overcame the drawbacks of the above-mentioned conventional technology and developed a lightweight construction panel that is lightweight, has enough strength and rigidity to withstand use as a load-bearing structural wall, and is easily available in various shapes. As a result of intensive research, the inventors discovered that the objective could be achieved by using a rigid core material with a fixed-shaped through-hole as the core material of the sandwich panel, and were able to complete the present invention. That is, the present invention has a large number of cavities penetrating in parallel in one direction,
and the cross-sectional shape of the cavity passing through the rigid core material is formed by alternately combining a quadrangular shape with two sides parallel to the surface of the rigid core material and two quadrangular shapes of the same shape adjacent to the quadrangular shape, or The present invention provides a lightweight construction panel with surface materials stretched on both sides.

Next, the architectural panel of the present invention will be explained in more detail based on the drawings. FIG. 1 shows a cross-sectional view of the panel of the present invention, in which the core material 1 is
It is necessary to have a rigid core material having a large number of cavities 3 penetrating in parallel in one direction. This is because the weight can be reduced by providing a large number of cavities 3, and the cavities can be filled with a foam material having excellent heat insulation and sound insulation effects. Further, in order to prevent the strength of the core material from decreasing even when a large number of through cavities are provided, the directions of penetration of the cavities must all be in the same direction. Further, preferred embodiments of the shape of the cavity include a rectangular tube shape and a rectangular cross-sectional shape having two sides parallel to the surface of the rigid core material;
It is formed by alternately combining two squares of the same shape adjacent to the square. With such a shape, the core material becomes structurally extremely strong. There are no particular restrictions on the material of this core material, but thermoplastic resins, thermoplastic resins with fillers, thermosetting resins, thermosetting resins with fillers, inorganic substances, inorganic materials with fillers such as glass fiber reinforced cement, etc. Alternatively, metal is preferable. The core material can be manufactured by integral molding by extrusion or pultrusion, or by welding or adhering the molded products to each other or to a plate-like material, and continuous production is also possible.

Next, in the panel of the present invention, the through cavity 3 of the core material 1 may be left as is, but if necessary, the cavity may be filled with foam material. By filling with foam material, a panel with excellent heat insulation and sound insulation effects can be obtained. It is not necessary to fill all the cavities of the core material with the foam material, and depending on the purpose, it is possible to fill only a portion of the cavities and leave the other portions empty. Any type of foam material may be used here, and it is possible to use either an organic foam material or an inorganic foam material.

In the panel of the present invention, the material of the surface material 2 stretched on one or both sides of the core material varies depending on the purpose, but is generally metal, asbestos cement, gypsum, etc.
Synthetic resins, filler-containing synthetic resins, and the like are suitable. The surface material 2 can be attached to the core material 1 by a conventional method such as heat bonding, welding, or bonding with an adhesive.

Architectural panels having the structure described above are lightweight, yet have excellent strength and rigidity.
Furthermore, by filling the cavity of the core material with a foam material, sufficient heat insulation and sound insulation effects can be achieved, and by adjusting the filling amount of the foam material, the heat insulation and sound insulation functions can be changed as appropriate. Furthermore, the cavity inside this panel can be used for various types of piping, and if various types of piping are installed in advance, piping work can be carried out extremely efficiently.

Therefore, the panel of the present invention having the above-mentioned advantages can be extremely effectively used as a load-bearing wall material for prefabricated houses.
