Connecting structures

Abstract

To provide a connecting structure that connects columns on upper and lower floors and is suitable for medium and high-rise buildings.SOLUTION: A connecting structure 100 connects a lower floor column 1 and an upper floor column 2, and has a connection hardware 130 provided between the lower floor column 1 and the upper floor column 2, a second bolt 120 protruding from the lower floor column 1 toward the upper floor column 2, and a pair of second nuts 121 screwed onto the second bolt 120. The connection hardware 130 has a lower surface portion 131 through which the second bolt 120 penetrates, and an upper surface portion 132 that is fixed to the upper floor column 2. The lower surface portion 131 is sandwiched from above and below by the pair of second nuts 121 that are screwed onto the second bolts 120. Furthermore, the connection hardware 130 has a lower surface portion 131, an upper surface portion 132, and a side portion 133 connecting the lower surface portion 131 and the upper surface portion 132. The side portion 133 is more extensible than the lower surface portion 131 and the upper surface portion 132.SELECTED DRAWING: Figure 1
