Description

  In particular, the present invention relates to a composite plate suitably used as a partition for partitioning a space, and a reinforcing member used for the composite plate.

  Conventionally, a composite board is used as a partition for partitioning a space around a water such as a toilet booth or a shower booth (for example, Patent Document 1). The composite board described in Patent Document 1 has a structure in which a honeycomb structure made of kraft paper is sandwiched between two melamine decorative boards. According to Patent Document 1, it is lightweight and excellent in water resistance.

  However, the composite plate of Patent Document 1 has different surface strength between the void portion and the other portions, and the surface strength of the void portion is only the strength of the melamine decorative board made of melamine resin, and there is a portion where the surface strength is locally small. is there. The melamine decorative board generally has the property of being relatively easy to break when it is thin, so if the part is subjected to an impact with a sharp object such as an umbrella, the melamine decorative board breaks and the internal voids are exposed. There is a problem of end.

  Therefore, in recent years, a structure has been developed in which a plate-like foamed resin molded body is used as the core material instead of the honeycomb structure, and the foamed resin molded body is sandwiched between melamine decorative boards. According to this structure, since the substantially entire surface of the melamine decorative board is supported by the foamed resin molded body, it is possible to suppress a local decrease in surface strength.
