TRANSITION NODE AND CONSTRUCTION METHOD OF HOLE RESERVED IN BASEMENT WITHOUT BEAM-COLUMN CAP
In view of the difficulty in the construction of the multi-storey basement structure system and the inner support structure,the transition node of the basement without beam-column cap reserve hole and its construction method are introduced,which means that the multi-storey underground supporting structure is not removed during the construction of the basement structure.The structural column,steel pipe column and column cap in the main structure cannot be constructed synchronically to the corresponding structural plate through the inner support ring beam,so it is necessary to set the corresponding reserved hole of the structural plate and use I-beams and shear keys to strengthen the hole to meet the force transmission requirements of the horizontal structure of the structural plate.This method has the characteristics of good integrity,high safety,convenient construction,saving time and saving cost.
