Overhung I steel hole embedded construction process

The invention discloses an overhung I steel hole embedded construction process. The overhung I steel hole embedded construction process involves foam embedded parts and a dust collector. The lengths of the foam embedded parts are equal to the thickness of a shear wall, the cross sections of the foam embedded parts are of rectangular structures, I type passageways matched with the cross section structure of overhung I steel are formed in the cross sections of the foam embedded parts in a penetrating manner, and the overhung I steel penetrates through the I type passageways of the foam embeddedparts. The overhung I steel hole embedded construction process includes the following steps that 1), overhung I steel holes are preformed between a floor and the shear wall, the foam embedded parts are put at the hole reserved positions of the bottom of the shear wall, the foam embedded parts are fixed to vertical rebars of the shear wall through binding wires, the foam embedded parts are flush with the shear wall, and th
