Description
Technical field
The present invention relates to concrete filled steel tube technical field more particularly to rectangular steel-tube concrete column-beams of concretes
Staggered joint structure.
Background technique
Rectangular steel tube with concrete infilled had not only had the characteristics that the good ductility of steel construction and anti-seismic performance, but also overcame round steel
Pipe concrete structure as section it is special and caused by it is cumbersome in design and construction, and have that bending stiffness is big, node connection
The advantages that easy.Therefore, rectangular steel tube with concrete infilled possesses preferable application prospect in executive information systems,
Most attention by domestic and international project field.
Rectangular steel-tube concrete column-beams of concrete can integrate the respective advantage of both steel and concrete, and combination becomes second nature
Can multiplication component, have many advantages, such as that its bearing capacity height, ductility is good, remarkable in economical benefits, easy for construction.
Node directly affects the performance of monolithic architecture structure as power transmission hinge important in structure, design.On ground
It shakes under load action, node, which will have enough strength and stiffness and good ductility and energy consumption, can meet building structure pair
The Seismic Design Requirements of node.
The complicated multiplicity of steel core concrete column-concrete girder connection form.But generally with concrete-filled circular steel tube column-coagulation
Native girder connection and concrete-filled circular steel tube column-connected mode are in the majority, these two types of nodes often economic benefit, construction simplification and power
Learning performance cannot be considered in terms of, and provide biggish optimization space to the implementation of beam-column joint.Rectangular steel-tube concrete column-is mixed at present
Solidifying soil girder connection form is relatively fewer.
With the diversified development of modern architecture, staggered joint in practical projects using increasing, it is common to be
Conventional steel bar concrete Vierendeel girder-column staggered joint, it is relatively fewer for the staggered joint form of other structures type, such as rectangle
Concrete filled steel tube staggered joint and steel reinforced concrete structure staggered joint.
The vertical member quadrangle of Zhenjiang Suning, The East Pagoda building, square item body structure is rectangular steel-tube concrete column, in structure
The Vierendeel girder in portion is connect using section steel beam with steel core concrete column, and in basement partially due to the change of operating condition, needs into one
Step optimization beam-column joint connection.
Novel rectangular steel core concrete column-the concrete girder connection that can be looked at present is mostly leveling node, and in rectangular steel plates
Aperture is more or bolt welding connection is more, and excessive hole generates stress and concentrates, and influences the carrying energy of steel core concrete column
Power and anti-seismic performance.About staggered joint, only have grinding for a small number of girder with rolled steel section en cased in concrete-profile steel concrete column abnormal joints at present
Study carefully, the research of rectangular steel-tube concrete column-beams of concrete staggered joint there is no and can look into.
Summary of the invention
Goal of the invention: the present invention provides the staggered joints of a kind of rectangular steel-tube concrete column and beams of concrete, solve
The problem of economic benefit, construction simplification and mechanical property cannot be considered in terms of in the prior art, while solving existing node influence
The problem of bearing capacity and anti-seismic performance.
Technical solution: the staggered joint of rectangular steel-tube concrete column and beams of concrete of the invention, including rectangular steel pipe are mixed
Solidifying earth pillar and two beams of concretes being connect respectively with its two sides by earth system, the earth system includes that several layers are set
In in rectangular steel-tube concrete column and diaphragm plate corresponding with beams of concrete position, be set to the beams of concrete in and and diaphragm plate

Rationally, lateral rigidity is big, and bending resistance is strong.
The diaphragm plate is equipped with four layers, and two side wing edges of the H profile steel bracket wherein one end are corresponding with position respectively
The connection of two diaphragm plates.Diaphragm plate is fixed and is welded with H profile steel bracket, to guarantee that Shear force within the beam end and moment of flexure can be effectively
It is transmitted on rectangular steel-tube concrete column.
The plate thickness of the diaphragm plate is identical as the plate thickness on the upper and lower edge of a wing of H profile steel bracket, is slightly less than concrete-filled rectangular steel tube
The plate thickness of column.
The hole that can be inserted into for diaphragm plate, and the diaphragm plate, steel ox are offered in the rectangular steel-tube concrete column
Leg and rectangular steel-tube concrete column collectively constitute steel construction part.The rectangular steel-tube concrete column arranged on left and right sides steel plate
The hole of two rectangles, the hole and diaphragm plate of the rectangle are respectively equipped in the beam contour line with beams of concrete adjacent interfaces
Position corresponds, size of the size slightly larger than the cross section of diaphragm plate.The diaphragm plate is inserted into rectangle by the hole of rectangle
It in steel core concrete column, being completely disposed in rectangular steel-tube concrete column, is horizontally arranged, post jamb is close in H profile steel bracket cross section, with
H profile steel bracket, rectangular steel-tube concrete column collectively constitute steel construction part.
The steel reinforcement cage is set in the beams of concrete, including longitudinally disposed several reinforcing bars and stirrup.Pass through longitudinal steel
The overlap joint of steel reinforcement cage and H profile steel bracket that muscle and stirrup are formed, realizes the connection of concrete column and rectangular steel-tube concrete column, keeps away
The cumbersome of live reinforcement welding is exempted from, so that rainy weather construction is unaffected；Wherein, the H profile steel bracket and steel reinforcement cage
Material and size are all the same.
The diaphragm plate is equipped with double shear stud, and the shear stud on adjacent two diaphragm plate shifts to install；The H-type
Two side wing edges of steel corbel are equipped with double shear stud, and are located in the steel reinforcement cage.Double shear stud is to guarantee steel plate
Do not occur bond-slip between concrete, wherein the material and size of the H profile steel bracket and the shear stud on diaphragm plate
It is all the same.
The utility model has the advantages that 1, present invention construction is simple: beams of concrete by reinforcing bar and H profile steel bracket overlapped mode realizes and
The connection of rectangular steel-tube concrete column avoids the cumbersome of live reinforcement welding, so that rainy weather construction is unaffected；2, it saves
About cost: reducing welding, and being changed to that overlapped, mode can save electric energy, reduces cost of labor, economy obtains a degree of
It is promoted；3, quality controllable: the rectangular steel pipe with internal partition, H profile steel bracket, diaphragm plate and double shear stud can be wanted according to design
The drawbacks of asking to weld in factory and complete, then being transported to construction site, avoid live human weld, realizes the quality of node weld seam
Controllably；4, load transmitting is clear: under external load effect, beam-ends moment of flexure and shearing can reinforcing bar encrypts block transitive by overlapped
Rectangular steel-tube concrete column is transferred to H profile steel bracket, then by H profile steel bracket and diaphragm plate；5: anti-seismic performance is promoted: concrete
The reasonable split-level height of beam makes the bearing capacity of node and anti-seismic performance increase compared with leveling node；6, application is strong: working as square
When left and right standard width of a room in an old-style house layer high difference occurs in shape concrete filled steel tube, which can satisfy the needs of engineering design,
To increase selection for the design of beam-column joint in rectangular steel tube with concrete infilled.
