Welded with monoblock type junction steel plate (15)；Determined between steel pipe column (12) by internal lining pipe (21) and locator card (24)
Position, is attached, and steel pipe column (12) and arc backplate (25) link position are entered by bolt (23) and arc backplate (25)
Row welding；
Step 5: steel pipe column (12) and steel pipe core connection：Steel pipe column (12) and steel pipe stem (29) are carried out with connection fin (30)
Connection；Steel pipe column (12) is in termination along slot at axis cutting 4, and the top of steel pipe column (12) is located on flooring 1 meter, will connect wing
In piece (30) insertion steel pipe column (12) slot, steel pipe column (12) slot is then carried out with being connected fin (30) full weld to this section of post
Reinforcing bar colligation, punching block are installed and concreting；
Step 6: at levels beam-column node steel pipe stem (29) connection：Reinforcing bar fixing steel plate (42) passes through positioning screw
(41) positioned, beam main tendon (43) is attached by straight screw sleeve (39) with reinforcing bar fixing steel plate (42), reinforcing bar positioning
Steel plate (42) is welded and fixed with steel pipe stem (29) and tooth form backplate (40), then carries out reinforcing bar colligation, punching block to the section
Install and concreting, vibrated in concreting process by the hole of vibrating (45) on reinforcing bar fixing steel plate (42)；
Step 7: the connection of steel pipe stem (29) and shaped steel stem (35)：In the company of steel pipe stem (29) and shaped steel stem (35)
Place is met, in steel pipe stem (29) termination along slot at axis cutting 4, shaped steel is inserted and full with shape steel web toward slot during installation
Weldering, then carries out reinforcing bar colligation, punching block to the section and installs and concreting.
