10. the vertical dry type connection of the prefabricated assembled frame column with shearing resistance keyway as described in any one of claim 1-9
The engineering method of node, which is characterized in that specific step is as follows:
Step 1: installation mold and pouring prefabricated post:
Simultaneously built-in connection (4) are arranged in mold in S1, installation first floor column (3) mold, in first floor column (3) top end mould setting the
The second shear key frid (11) is arranged in one shearing resistance keyway plate (10), first floor column (3) bottom；
Rectangular gap (8) are arranged in S2 in top end mould；
S3 installs upper strata post (6) mold, and the second shear key frid (11) is arranged in its bottom；
Rectangular gap (8) is arranged in upper strata post (6) bottom in S4；
Step 2: formwork and pouring basic (1):
When formwork, the first shear key frid (10) is set at the top of basic (1), while setting is connected with energy consumption in basic (1)
The steel bar connector (2) of part (7) connection；
Step 3: smearing high-strength epoxy resin on the surface of the first shear key frid (10) of basic (1)；
Step 4: installation first floor column (3), adjusts verticality and installs suspension column:
The lower end of energy consumption connection plug (14) is sequentially passed through into third circular hole (9) and steel sleeve (15) on built-in connection (4)
And connect with basic (1) interior steel bar connector (2), the upper end of energy consumption connection plug (14) is secured with nuts in built-in connection
(4) on；
Step 5: high-strength epoxy resin is smeared on the first shear key frid (10) surface at the top of first floor column (3)；
Step 6: installation upper strata post (6), after the first shear key frid (10) is engaged with the second shear key frid (11), the first circle
The center of circle in hole (12) and the center of circle of the second circular hole (13) are located on same axis, adjust verticality, and bolt is each passed through the first circle
Hole (12) and the second circular hole (13), and fixation is tightened, complete the connection of first floor column (3) and upper strata post (6).
