Description
Technical field
The utility model belongs to Concrete Filled Square Steel Tubular technical field, more particularly to a kind of steel core concrete column and steel
Beam, steel diagonal brace connecting node.
Background technology
Concrete Filled Square Steel Tubular as a kind of new composite structure, with anti-side rigidity is good, sectional dimension is small and compared with
The joint form of circular steel tube concrete post is simple, architectural composition is flexible, cross sectional moment of inertia is big, stability is good, easy construction,
The advantages of fire prevention measure is easy, makes to have obtained in its many at home and abroad, high-rise steel structure house and high level, super-high building structure
Increasingly it is widely applied.However, the subject matter of restriction Concrete Filled Square Steel Tubular popularization and application at present is mixed to square steel tube
The research of solidifying earth pillar-steel beam joint construction, inquires into reasonable, effective joint structure scheme, with highly important theory significance
And application value.
When horizontal member is girder steel, the way in pure steel structure can be used in rectangular steel tube with concrete infilled.At present,
The linked vector graph of four kinds of rectangular steel-tube concrete columns and girder steel is recommended in code：
1st, band short beam internal partition formula connection.Dividing plate, the short girder steel of column outer wall prewelding are set in rectangular steel pipe；Steel beam flange and post side
Default short girder steel butt welding connection, the web of girder steel and the web double plate bolt connection of the short girder steel of prewelding.
2nd, overhanging internal partition formula connection.Dividing plate is set in rectangular steel pipe, dividing plate passes through post jamb, and steel pipe welding is on dividing plate；Girder steel
Web uses high-strength bolt friction-type connection with post steel pipe walls by connecting plate；Steel beam flange is welded with overhanging internal partition.
3rd, external partition formula is connected.Steel beam web plate uses high-strength bolt friction-type connection with default connector outside post；Post
The horizontal external partition of peripheral hardware, steel beam flange is welded to connect with external partition.
4th, internal partition formula is connected.Steel beam web plate uses high-strength bolt friction-type connection with post steel pipe walls by connecting plate；
Dividing plate is set in rectangular steel-tube concrete column, steel beam flange is welded with post steel pipe walls.
Four kinds of connected modes of summary, it is seen then that the steel tube concrete without diagonal brace in frame structure is only gived in code
The simple connecting node of earth pillar and girder steel, does not there is the section for providing and having diagonal brace to intersect at beam column complex situations in frame-brace structure
Point construction.If according to the dividing plate in the increase steel core concrete column of the make machinery of code connecting node, to connect tiltedly
Support, the make of second and third above-mentioned kind can cause the exposed influence architectural effect of dividing plate, and first and the 4th kind of construction
Mode can cause internal partition excessively to influence the pouring quality of steel pipe column interior concrete.Due to diagonal brace in frame-brace structure system
It is that, by axle power component, the tension and compression of diagonal brace need to consider the web for setting vertical baffle to align diagonal brace rationally to transmit oblique compared to beam
The axle power of support, but set vertical dividing plate that intra-node construction can be caused more complicated, and will can separate inside steel tubular column joints
Into interior storehouse two small, make the perfusion of concrete more difficult.
Node is the pith of overall structure composition, is the bridge cooperated between component.Current structure design
Specification only gives computational methods and detailing requiments to typical steel pipe concrete column-steel beam node, and in high-rise steel structure
Widely used steel core concrete column not yet provides clear and definite tectonic sieving with girder steel, the connecting node of steel diagonal brace and provided, so that
It result in that some engineering interior joints construction is complicated, steel using amount is big, processing and manufacturing difficulty is high, and therefore cause Pipe Welding Quality again
The vicious circle being difficult to ensure that with interior filling concrete pouring quality.
For case above, design a kind of construction directly, effectively, with higher bearing capacity and preferable plastic deformability
The reasonable node that the steel core concrete column of energy is connected with girder steel, bracing members is particularly necessary.
