Construction Technology for Strengthening of Newly Added Steel Beam in Existing Structure
The new technology adopts a new prefabricated and adjustable moulding bed for the installation of newly added steel beam.The moulding bed is fixed by the front end of the fork-lift truck,and the newly added steel beam is placed on it,and the displacement is prevented by the restraint column.The fork-lift truck lifts and reinforces the steel beam to the scale height,and the other fork-lift truck transports the pre-welded support frame to the bottom of the steel beam,and installs the detachable support and the jacking bracket to closely connect with the floor slab.The support frame and the jack are used together to realize the rapid installation of steel beams at different sections and the rapid turnover of the support frame.This paper introduces this technology in detail,and highlights the collaborative operation of large fork-lift truck,new prefabricated and adjustable molding bed,and adjustable support frame,which provides an effective means for efficient strengthening of old buildings.
