Embodiment Construction
[0032] The present invention is described in detail below in conjunction with accompanying drawing: low-frequency shock-absorbing square nine hole pile earthquake superstructure comprises the first hollow steel pipe (1), the second hollow steel pipe (2), the 3rd hollow steel pipe (3), the 4th hollow steel pipe ( 4), the fifth hollow steel pipe (5), the sixth hollow steel pipe (6), the seventh hollow steel pipe (7), the eighth hollow steel pipe (8), the ninth hollow steel pipe (9), the rubber column (10) and concrete layer (11).
[0033]First, install a rubber column with a reserved hole, the size of which is 2cm larger than the cross-sectional area of the square steel tube column. With the centroid of the interface of the rubber column as the center, a coordinate system is established at the cross section. The reserved holes are from top to bottom. The coordinates of the center positions of the first row of three holes are: (-0.5m, 0.5m) (0,0.5m) (0.5m,0.5m); The coordinate...
