Novel prestressed concrete resistance to compression short column that takes precautions against earthquakes

The utility model discloses a novel prestressed concrete resistance to compression short column that takes precautions against earthquakes, including short column, damping device, damping device includes bottom suspension fagging, support column, support medium plate, pressure -bearing spring, goes up the backup pad, supports axis, second support column and second backup pad, and short column, support column, support axis and second support column all set up on the bottom suspension fagging, supports the medium plate setting in support column mid point position, go up the backup pad with the support column, support in the hub connection, pressure -bearing spring sets up between support medium plate and last backup pad, the nut is passed through to the second backup pad and the second support column is connected. The utility model discloses simple structure, design benefit for the short column increases by one set of damping device, pushes down, is equivalent to behind the pressure -bearing spring pressurized and applys a prestressing force for the short column that this prestressing force can replace the post keep out partly pressure, has improved resistance to compression, the anti -seismic performance of short column to last backup pad through the nut to it has high ductility polyester fiber cloth layer to wrap up in to cover, increases the whole fatigue strength of building.
