Metal (aluminum, etc.) on both sides of the honeycomb core,
The honeycomb sandwich structure with surface materials such as FRP, plywood, and inorganic boards (asbestos cement boards, etc.) is lightweight (because the space volume is extremely large) and has strong strength and rigidity for its weight. Furthermore, because it has heat insulating properties, sound insulating properties, etc., it is widely used as a structural member of aircraft, vehicles, buildings, etc.

である。 Honeycomb core materials include metal cores such as aluminum and stainless steel, plastic cores,
There are many types such as FRP core and paper core.
Although paper honeycomb cores are advantageous from the viewpoint of material cost and processing, they have problems such as being easily flammable because they are made of paper, having low strength, and having poor adhesion to surface materials. These problems also apply to resin-impregnated paper honeycomb bodies.

However, since the honeycomb core 1' of the above-mentioned structure is composed of paper and a hardened magnesia cement 3' coated on the surface thereof, its strength, especially when wet, is insufficient. In addition, if the honeycomb structure is exposed to a fire or the like, the paper portion of the honeycomb core will be thermally decomposed or burnt down, forming interconnected cavities, resulting in a significant decrease in strength and the tendency for peeling to occur along the cavities. .

When such china paper or noncombustible paper is origami-crafted to form a honeycomb structure, adhesion between the papers and the honeycomb layer made of the paper and the surface material becomes difficult, and peeling is likely to occur. In particular, heat-resistant adhesion is difficult.

という。 The honeycomb body of the present invention is formed by folding the cement paper into a honeycomb configuration and bonding the honeycomb configuration contacts with a cement adhesive. The honeycomb usually has cavities in the shape of polygonal columns, typically triangular, square or hexagonal columns. The dimensions of the cavity are arbitrary, but for example, several centimeters in diameter, typically about 1 to 1 cm in diameter.
It is a polygonal column inscribed in a circle about 10 cm in size. Cement paste, mortar, etc. are used as the cement adhesive. When the adhesive contains an appropriate amount of aggregate, such as mortar, the aggregate is aggregate powder that is thermally stable when fired at temperatures up to about 950°C, similar to the aggregate contained in cement paper. This is desirable from the viewpoint of subsequently firing the honeycomb. If the honeycomb is subsequently fired to burn off the pulp and rehydrate the cementitious components, it is generally desirable for the adhesive to consist solely of a cementitious adhesive. When used as is for lightweight structures without firing, mixing a resin such as rubber latex or acrylic emulsion with the cement adhesive improves adhesiveness, increases cement strength, and increases shear impact resistance. In this specification, these are collectively referred to as cement adhesives.

れる。 Typical usage modes of the honeycomb body according to the present invention are illustrated below; the honeycomb body has sufficient strength due to the continuous bonding of the cement components in the cement paper and the cement components in the adhesive. The honeycomb body can be coated with a paint such as water glass to improve its waterproof properties, and after applying the glaze to the desired surface of the honeycomb body, it is fired and rehydrated to glaze the outside. A resin-treated honeycomb body is obtained by firing the honeycomb body to burn off the pulp material and the like, and then impregnating the honeycomb body with a resin liquid and polymerizing and hardening the honeycomb body. These honeycomb bodies can be used as structural materials in their own right. Furthermore,
A plate-like honeycomb structure can be advantageously obtained by bonding a plate-like material to one surface or two surfaces of the honeycomb body. At this time, by filling the honeycomb space with a heat insulating material, a heat and sound insulating structure can be easily obtained.
