Summary of the invention
The present invention is directed to the deficiency that existing engineering exists, on the basis considering compound concrete filled steel tube own profile feature, provide a kind of novel compound concrete-filled tubular column-girder steel half punching haunch type design of node scheme.
Compound concrete-filled tubular column-girder steel half punching haunch type node of the present invention, is made up of compound concrete-filled tubular column, girder steel and Force transmission parts.Described compound concrete-filled tubular column comprises outer steel pipe 1, interior steel pipe 2 and the inner concrete 3 poured into, and described girder steel 4 comprises bottom flange and web, and described Force transmission parts is oblique armpit plate 5.It is characterized in that: it is inner to interior steel pipe 2 place that girder steel 4 stretches into outer steel pipe 1, welds, and be embedded in concrete 3 with interior steel pipe 2 wall; Girder steel 4 and outer steel pipe 1 intersection carry out weld reinforcement; On girder steel 4, being welded with oblique armpit plate 5 between bottom flange place and the outer steel pipe 1 of compound concrete-filled tubular column simultaneously, for ensureing oblique armpit plate 5 stability, welding vertical floor 6 in oblique armpit plate 5 side towards beam column intersection.
Described compound concrete-filled tubular column type is compound hollow steel pipe concrete column or real compound concrete-filled tubular column, and the cross section combining form of interior steel pipe and outer steel pipe is: inner circle cylindrical, Nei Fang foreign side, inner circle foreign side, the outer rectangle of square internally and round externally or interior rectangle, interior rectangle foreign side shape, interior rectangle outer ring.Described concrete is ordinary concrete or high-strength concrete or self-compacting concrete.The thin-wall steel tube that described interior steel pipe and outer steel pipe all adopt the ratio of round steel pipe external diameter or the square steel pipe length of side or rectangular steel pipe length of short sides and thickness of steel pipe to be greater than 20.The steel of described steel beam column can adopt regular tenacity steel or yield strength at the high-strength steel of more than 460Mpa.Described oblique armpit plate adopts rectangular steel plates, and steel beam flange is wide and the two angle should remain between 30 ° and 60 °; The vertical floor of its side can need to adopt differing heights according to design, and vertical floor all adopts twin fillet wolt to be connected with oblique armpit plate, girder steel, outer steel pipe intersection.
Beneficial effect:
1, compound concrete-filled tubular column-girder steel half punching haunch type node of the present invention; girder steel half punching can ensure effective transmission of girder steel Shear force within the beam end and moment of flexure; girder steel beam-ends moment of flexure has been shared in the existence of oblique armpit plate; beam-ends plastic hinge can be realized; reach the object of protection nodes domains, improve the bearing capacity of node.Therefore this node bending resistance shear resistance is strong, Path of Force Transfer is clearly reliable, easily meets the requirement of rigid joint, realizes strong column and weak beam, seismic design object that node is stronger.
2, compound concrete-filled tubular column-girder steel half punching haunch type node of the present invention, directly penetrates outer steel-pipe welding in interior steel pipe walls, does not do any perforate process, can greatly reduce the workload of field operation, be conducive to accelerating construction progress girder steel by girder steel.
3, compound concrete-filled tubular column-girder steel half punching haunch type node of the present invention, there is good looking appearance, simplicity of design, construction costs be low, concrete is easily built, the advantage such as constructability, and excellent in mechanical performance, can be widely applied in high level, Super High combining structure and steel reinforced concrete combined bridge structure.
