On the other hand, in each drawing, a configuration that can be easily understood by those in this field from a general technique, and an operation and a detailed description thereof have been simplified or omitted, and parts related to the present invention are mainly illustrated.

Figure 2a is a perspective view showing a building panel according to the first embodiment of the present invention, Figure 2b is a cross-sectional view showing a building panel according to the first embodiment of the present invention, Figure 3 is a building panel according to the first embodiment of the present invention Is an enlarged cross-sectional view

2A to 3, the building panel 1 according to the first embodiment of the present invention includes a first fiber-reinforced board 11, a second fiber-reinforced board 12, and a first fiber-reinforced board 11. The filled concrete layer 13 to be filled and cured between the and the second fiber reinforced board 12 is composed of one assembled molded body.

The first fiber-reinforced board 11 is composed of an approximately square high-density plate, and is composed of cellulose fibers 111 and 121 such as coconut stems, cement, and silica as the main components, and additives and water are mixed therein and added to a mold (not shown). It is manufactured by putting it in, pressurizing it at high pressure, going through an autoclave curing process, and removing the mold.

Here, the heat insulating member 15 typically applies foam resin grains in consideration of mixing properties with concrete mortar and workability.

In addition, as the foamed resin granules, granules swollen with steam by injecting hydrocarbon gas or the like into a polystyrene resin may be used. The foamed resin granules formed in this way have a resin of about 2% and 98% of the volume of air, so their specific gravity is very small, so that the weight of the building panel can be significantly reduced, and since most of them are air layers, they have excellent thermal insulation and thermal insulation performance. In addition, in the present embodiment, since the foaming resin particles are discarded as waste, and thus foaming resin particles that cause environmental pollution can be used, it is environmentally friendly and has the advantage of reducing manufacturing cost.
