<P>PROBLEM TO BE SOLVED: To provide a joint material which copes with the unevenness of a joint material installation surface and facilitates manufacturing and installation work to solve the problems of conventional techniques, and to provide a slit structure installed with the joint material and a construction method for the slit structure. <P>SOLUTION: A laminated joint material is installed in a slit provided between a concrete structure and another concrete structure, and comprises a first layer and a second layer which are different in material from each other. The first layer is made of a material having fire resistance performance higher than that of the second layer, and the second layer is made of a material having elasticity higher than that of the first layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
