Abstract
The invention relates to an anchor plate steel tube concrete post-cap combined beam connecting node, wherein said node comprises steel tube concrete 1, hidden leg 2, upper longitudinal steel bar 3, hoop reinforcement 4, lower longitudinal steel bar 5, U-shape section steel beam 6, transverse steel bar 7, T-shape anchor plate 8, steel plate 9, and anti-shear connector 10; the inner wall of steel tube of steel tube concrete 1 is arranged with T-shape anchor plate 8, while the outer wall is arranged with hidden leg 2 and upper and lower symmetry steel plates; the upper and lower longitudinal steel bars are welded with upper and lower symmetry steel plates. The invention first welds or bends the steel plate into U-shaped steel beam to be welded with anti-shear connector 10; then pours concrete to form the combined element. The invention has low cost, simple structure, and better physical property.
Description
Technical field
The present invention relates to a kind of novel steel core concrete column-girder steel connected node, belong to technical field of structural engineering.
Cost is low, simplicity of design, and good mechanical performance, anti-seismic performance and fireproof performance are good, reduce depth of beam and increase the house headroom, reduce template and accelerating construction progress, have bright development prospect.
Background technology
At present, conventional steel core concrete column-steel concrete connected node node area be provided with reinforced concrete circle beam or reinforced steel bar ring around or the punching member, but complex structure, use not attractive in appearance.Anchor plate type steel core concrete column-u shape composite beam connected node is compared simple structure with the steel core concrete column-steel concrete connected node of routine, good mechanical performance, topology layout is convenient, can reduce depth of beam and increase the house headroom, reduces template and accelerating construction progress; Compare with the steel core concrete column-girder steel connected node of routine, structural bearing capacity and bending rigidity improve, and fireproof performance is better.Studies show that both at home and abroad: shape for hat cross section compound beam has higher capacity, rigidity and ductility, can give full play to the structure and the economic advantages of combining structure.
Summary of the invention
A kind of novel steel tube concrete column and the u shape composite beam connected node that the object of the present invention is to provide, this node cost is low, simplicity of design, good mechanical performance, anti-seismic performance and fireproof performance are good, reduce depth of beam and increase the house headroom, reduce template and accelerating construction progress, have bright development prospect.
A kind of anchor plate type steel core concrete column-u shape composite beam connected node that the present invention proposes, it is characterized in that: described node contains concrete filled steel tube (1), hidden bracket (2), upper strata longitudinal reinforcement (3), stirrup (4), lower floor's longitudinal reinforcement (5), U type section Steel Beams (6), transversely distributed steelbar (7), T type form anchor (8), steel plate (9), shear connector (10); Steel pipe inwall in the described concrete filled steel tube (1) is provided with T type form anchor (8), and outer wall of steel pipe is provided with hidden bracket (2) and symmetrical up and down steel plate (9), upper strata longitudinal reinforcement (3) and lower floor's longitudinal reinforcement (5) respectively with the welding of symmetrical steel plate (9) up and down; Described u shape composite beam is that steel plate welding or clod wash are become U type section Steel Beams, welds shear connector (10) disturbing concrete on U type section Steel Beams, the compound section member of formation.
In above-mentioned anchor plate type steel core concrete column-girder steel connected node, described node is divided into anchor plate type concrete-filled circular steel tube column-girder steel connected node, anchor plate type concrete-filled steel square tubular column-girder steel connected node, anchor plate type square steel core concrete column-girder steel connected node by the column section shape.
Because node provided by the invention is to be provided with T type form anchor at the steel pipe inwall, outer wall of steel pipe is provided with hidden bracket and last lower steel plate, and the levels longitudinal reinforcement welds with last lower steel plate respectively; U shape composite beam is that steel plate welding or clod wash are become U type section Steel Beams, welds shear connector on U type section Steel Beams, disturbing concrete, the compound section member of formation.At last, concreting in steel pipe column forms steel core concrete column-u shape composite beam connected node.Therefore, this structure has good seismic resistance, bearing capacity and rigidity, makes the joint cores simple structure, and is simple to operate, reduces depth of beam and increases the house headroom, reduces template and accelerating construction progress, gives full play to the effect of material and reduces engineering cost.Along with the extensive use of encased structures in engineering practice, this node pattern can adapt to the requirement of building structure layout flexibility, and uses attractive in appearancely, and then increases the usable floor area of structure, has the good engineering application prospect.
