<P>PROBLEM TO BE SOLVED: To provide a joint structure having a long life cycle, with one seal adjacent to the inner side of a building having high fatigue resistance among at least two neighboring seals to fill a joint space. <P>SOLUTION: A seal structure 10 comprises a joint space 4 formed between opposing end faces of two wall bodies P of a building, at least a primary seal 18A and a secondary seal 18B that are mutually adjacent to each other and arranged from outside to inside of the building in the joint space, and a separation part 20 that separates the primary seal and the secondary seal. The primary seal 18A and the secondary seal 18B are filled with a different unshaped sealing material to adhere tightly to the both wall bodies, so as to be deformable in a close contact state under compressive stress from the wall bodies. The secondary seal 18B has higher fatigue resistance to repeated compressive deformation and tensile deformation compared to the primary seal 18A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
