2. If the lower foundation of the wall has not been formed, it is recommended to directly embed the length of the column steel lining in the wall body, and it can be formally constructed after the wall maintenance period; or after the prefabricated embedded parts are laid on the wall plane, the column steel The lining is welded to the embedded parts by electric welding. These two methods are characterized by being stronger than the bolt connection, but the straight line and the horizontal line must be paid attention to when presetting.
3. The spacing of the column steel lining must be consistent with the design size to ensure that the pre-assembled semi-finished products can be connected to it.
