<P>PROBLEM TO BE SOLVED: To provide a base-isolation slit cover structure which is capable of preventing wind and rain from entering a body structure of a base-isolated structure while following up behaviors during earthquake. <P>SOLUTION: For a building of which the upper part is base-isolated by a base-isolation slit 10 extending approximately in a horizontal direction, in a base-isolation slit cover structure, a step 13 formed in the base-isolation slit 10 is covered. In the step 13, there are provided a rectangular four-side frame 31 and a door 32 which is provided to be opened/closed at an outer side of a building 1 of the four-side frame 31. The four-side frame 31 is divided into a first frame 40 including a lower frame 41 and a second frame 50 including an upper frame 51 along a diagonal. The door 32 is supported on the first frame 40 by a spring hinge 43, and a door stop 53 is provided at a position closer to the spring hinge 43 than the center of the upper frame 51. <P>COPYRIGHT: (C)2013,JPO&INPIT |
