Behavior how to reproduce the behavior reproduction apparatus and the joints of the joints

摘要

PROBLEM TO BE SOLVED: To provide a behavior reproduction device of a joint part capable of acquiring efficiently a highly-reliable test result in a short period by reproducing a behavior of the joint part based on a specification of an actual outer wall part or floor part, and reducing cost, and miniaturizable with a simple structure.SOLUTION: This behavior reproduction device of the joint part includes a plurality of plate materials 11, 61, etc., comprising outer wall plates or floor plates, and a backing plate 20 whose size is changed according to moisture absorption/release. The plurality of plate materials 11, 61, etc., are mounted in the juxtaposed state on the backing plate 20 so as to form joint parts 12, 62 between ends of the plurality of plate materials 11, 61, etc., and the plurality of plate materials 11, 61, etc., are allowed to move in an approaching/separating direction mutually corresponding to a size change according to moisture absorption/release of the backing plate 20, and thereby the joint parts 12, 62 are allowed to behave so as to increase/decrease a gap width therebetween.
