The exposed shaped steel and reinforcing bar of steel-concrete combination beam are stretched into welding type steel skeleton range of nodes and anchored；The cross weld type
The shaped steel specification and horizontal level of steel and prefabricated transfer structure for SRC beams are completely the same, are bolted or weld between the two
Connect in succession；The welding type steel skeleton node and prefabricated transfer structure for SRC beams beam-ends set local cast-in-place concrete, are formed
It is connected node.
Preferably, the vertical muscle Relatively centralized of the reinforced column is in corner, be easy to welding type steel skeleton node with
Prefabricated transfer structure for SRC beams in-site installation；Vertical exposed one section of muscle ensures to pass through node and anchors what is required in upper strata post
Length.
Preferably, the exposed shaped steel and reinforcing bar of the prefabricated transfer structure for SRC beams, exposed one section is easy to reinforcing bar soft
Property bending smoothly anchor into the length of intra-node to avoid welding type steel skeleton node, it is ensured that the construction of shaped steel joint connection in site will
Ask.
Preferably, reinforced steel bar strength, diameter and spacing and the reinforced column hoop reinforcement of the L-shaped horizontal reinforcement
It is required that identical.
Beneficial effect：(1) present invention is using welding type steel skeleton node, and on the basis of cross weld shaped steel, passes through
Set up closing batten plate frame and corresponding batten plate ribbed stiffener and shape steel web ribbed stiffener, effectively increase type steel skeleton bearing capacity,
Rigidity and ductile performance, meanwhile, additional L-shaped horizontal reinforcement is set to provide the constraint to position of joints concrete, by with
Upper construction measure, substantially improves the aseismic reliability of node, hence it is evident that improve the shock resistance of integral frame structure, and can be
Factory completes integral manufacturing, makes efficient, easy transportation and installation；(2) prefabricated transfer structure for SRC beams is used, is tied using combination
Structure component performance advantage, improves the span ability of structure level component；(3) node and beam-ends are locally cast-in-place, it is ensured that node
Globality, and thoroughly overcome steel structure node fire prevention and endurance issues；(4) outside beam-ends certain length shaped steel and reinforcing bar
Dew, is on the one hand easy to shaped steel in beam to be connected with node skeleton shaped steel, on the other hand can utilize reinforcing bar pliability, be easy to reinforcing bar to bend
And avoiding obstacles and stretch into intra-node；(5) post still uses reinforced column, is meeting the premise of structure stress requirement
Under, cost is reduced, the economy of node is fully improved.
