System overlapping coupled column T-type assembling type node.
Background technique
Portion envelops concrete combined component is a kind of new structural members that 1980s Europe proposes,
The basic pattern in section is the fill concrete between the edge of a wing of H profile steel component.This combined member big, rigidity with bearing capacity
Greatly, the advantages that fire resistance is good, there are no practical applications at home at present.
Steel core concrete column is the component that steel pipe and concrete filled are composed, and steel duct concrete is by steel pipe
Effect of contraction improves its bearing capacity, and the presence of concrete also constrains the inside buckling failure of steel pipe, and the structure is in high level
It is widely used in building.It is to grow up that steel tube concrete superposed coupled column, which is in concrete filled steel tube column foundation,
Reinforcing bar is set outside concrete filled steel tube, and new structural members made of casting concrete not only have steel core concrete column
Advantage, while the concrete outside steel pipe can delay the raising of steel beam columns under fire condition tube temperature degree, improve the fire resistance of column.
Current steel tube concrete superposed coupled column is mainly cast-in-place, is not prefabricated components, however as civil engineering
The gradually development of technology, for prefabricated components since its component processing quality is easy to get guarantee, speed of application is fast, connects between component
It is convenient, gradually obtain the concern of people.The part combination beam and prefabricated steel core concrete column of prefabricated steel connector facilitate production
While can reduce that molding amount, assembled in situ be convenient and reliable performance.
Mostly important in prefabricated components connection is exactly node, because the destruction of node may cause under geological process
The continuous collapse of total.If geological process flowering structure assembling type node will lead to structure entirety prior to component damage
Anti-seismic performance decline.In addition, prefabricated components are just being widely used in high-rise, large-span structure, high-rise, large-span structure fire-fighting difficulty
Greatly, to fire resistance, more stringent requirements are proposed.It is therefore proposed that more reasonably prefabricated components and node connection type, raising are pre-
Component processed improves anti-seismic performance, fire resisting reliability becomes the new demand of modern architecture development.
