The specific working process is as follows: when the energy absorption device designed by the invention is applied, when no earthquake occurs, the I-shaped fixing plate 8 of one of the first energy absorption unit 1 and the second energy absorption unit 2 is fixed with a beam on the lower side of a house, and the upper side structure of the energy absorption module 12 is limited by the fixing bolt 9 and the tightening ring 11; after an earthquake, the house is shifted and tilted, in which state the energy absorption module 12 is plastically deformed to absorb energy, at which time one rotates the worm 36 either manually or by means of mechanical rotating parts, if the energy absorption unit is rotated manually, because the I-shaped fixing plate 8 in the pressed energy absorption unit is still fixed with the beam and is pressed downwards by the house, so that the rotational resistance of the thread bush 13 in the compression energy absorption unit is larger than the rotational resistance of the thread bush 13 in the non-compression energy absorption unit, the worm 36 will drive the rotation of the drive shaft 15 in the uncompressed energy absorption unit, which drive shaft 15 rotates the corresponding threaded sleeve 13, through the thread matching of the thread bush 13 and the fixed support 14, the thread bush 13 will drive the corresponding undeformed energy absorption module 12 to move upwards, enabling the I-shaped fixing plate 8 in the uncompressed energy absorption unit to move upwards to be in contact with a house beam on the lower side of the house to support the house beam; after the energy absorption units are contacted, the I-shaped fixing plates 8 in the energy absorption units are extruded by the house beam on the lower side of the house, and frictional resistance is generated between the I-shaped fixing plates and the house beam; and after the original H-shaped fixing plate 8 on the pressed side supports the house beam on the other H-shaped fixing plate 8, the bolt connected between the pressed H-shaped fixing plate 8 and the house beam is removed, the resistance of the thread sleeve 13 in the original energy absorption module 12 on the pressed side is smaller than the resistance of the thread sleeve 13 of the energy absorption module 12 which props against the house beam at the moment, the driving shaft 15 corresponding to the driving shaft can be driven to rotate at the moment, and the driving shaft 15 rotates to enable the deformed energy absorption module 12 to move downwards for replacement.
After an earthquake occurs, and while ensuring that there is no aftershock, corrections are made for offset and tilted houses. Firstly, the fixed flange 17 and the fixed support 14 on the pressure side are fixed through bolts, the energy absorption module 12 on the non-pressure side is replaced by a component with higher strength, then the worm 36 is driven to rotate through the mechanical rotating component, the driving shaft 15 on the non-pressure side rotates, the non-pressure side is driven to move upwards, and the roof beam is jacked and corrected.
After the house beam is erected, pouring and supporting the lower side of the house beam, and after the support is solidified, manually controlling the rotary motion of the thread sleeves 13 in the two energy absorption units to keep the two energy absorption units away from the house beam; and the two energy absorption units are replaced by new energy absorption modules 12, and then one of the two energy absorption units is driven to move upwards, so that the I-shaped fixing plate 8 on the upper side of the I-shaped fixing plate is fixedly connected with the house beam.
