<P>PROBLEM TO BE SOLVED: To provide an exterior wall structure of wooden building, in which the thickness dimension of a layer consisting of calcium silicate plates is easily enlarged and which can be easily constructed. <P>SOLUTION: An exterior wall structure of wooden building comprises: a structural member 2 constituted with wood; a first fireproof coating layer 44 installed outside the structural member 2; a second fireproof coating layer 45 installed outside the first fireproof coating layer 44; and a third fireproof coating layer 46 installed outside the second fireproof coating layer 45, each of the first, second, and third fireproof coating layers 44, 45, and 46 being fabricated by laminating and integrating a plurality of calcium silicate plates, the calcium silicate plates constituting the second fireproof coating layer 45 having a larger thickness dimension and a lower density than those of the calcium silicate plates constituting the first and third fireproof coating layers 44 and 46. <P>COPYRIGHT: (C)2012,JPO&INPIT |
