Abstract
The invention relates to a steel tube concrete column with oblique stiffeners in side. The concrete column comprises a peripheral steel tube, wherein the inner wall of the peripheral steel tube is provided with stiffeners which are arranged obliquely and used for stiffening the two sides of the steel tube, and the peripheral steel tube is filled with concrete. The concrete column can ensure the two opposite sides of the steel tube column to be stressed together and enhance the shear resistance and bending resistance of the steel tube concrete column, so that the peripheral steel tube and concrete can cooperate with each other. The steel tube concrete column can enhance the restriction action on the concrete in the steel tube column and lower the relative sliding between the steel tube and concrete, thereby enhancing the bearing capacity of the steel tube concrete column.
Description
Technical field
The present invention relates to construction engineering technical field, particularly to the oblique steel core concrete column of putting more energy into of one kind inside band.
Background technology
Steel core concrete column refers to fill concrete in steel pipe and is formed and steel pipe and its core concrete can hold jointly
The structural elements being acted on by external load.Peripheral steel pipe provides Confinement effect so as to be in three dimension stress state to core concrete,
Thus improving its Compressive Bearing Capacity.
Because concrete filled steel rectangular tubes deform greatly under core concrete expansion, the constraint to inner concrete
Typically adopt circular cross-section steel core concrete column in declines, therefore engineering, but circular cross-section steel core concrete column is due to steel
Pipe outer wall is curved surface so that bean column node design becomes particularly complicated.One disclosed in China Patent No. cn201520552465.8
Plant entitled " concrete-filled circular steel tube column sleeve connection node " patent of invention；Disclosed in China Patent No. cn201410225322.6
A kind of entitled " a kind of steel core concrete column and beam connecting node " patent of invention etc., broadly falls into the such round steel pipe coagulation of solution
The patent of invention of native beam-to-column joint.
During using rectangle or odd-shaped cross section steel core concrete column, steel pipe inner wall need to arrange steel tie and put more energy into limit steel pipe
Out-of-plane deformation, but current steel tie puts more energy into general vertical welding in steel pipe inner wall, makes steel core concrete column bear horizontal lotus
During load, shearing cannot effectively transmit, and both sides steel pipe cannot collaborative work.
In sum, existing steel core concrete column has the disadvantage in that
1st, limited by cross-sectional shape: because rectangular steel pipe is under concrete compression expansion, pipe deformation is big, to internal mixed
The effect of contraction of solidifying soil weakens, and therefore concrete filled steel tube section typically adopts circular cross-section, and the steel pipe of rectangle or other shapes mixes
The low bearing capacity of solidifying earth pillar is in the concrete-filled circular steel tube column of identical material usage；
2nd, beam-to-column joint is complicated: because circular cross-section concrete filled steel tube column outer wall is curved surface so that bean column node design is multiple
Miscellaneous；
3rd, steel pipe and concrete binding effect are poor: Relative sliding easily occurs between steel pipe and concrete, mass action is poor；As
Strengthen the mass action of steel pipe and concrete, shear connector need to be set, construction is complicated.
4th, shear-carrying capacity is low: in steel pipe, fill concrete typically adopts plain concrete, and shear-carrying capacity is poor.
5th, be provided with steel tie in steel pipe and can improve the effect of contraction to concrete for the steel pipe, but steel tie can not improve anti-
Cut bearing capacity.In steel pipe, setting steel plate can improve shear-carrying capacity, but dramatically increases material usage and manufacture difficulty.
Content of the invention
For overcoming problems of the prior art, the invention provides a kind of oblique concrete filled steel tube of putting more energy into of internal band
Post, can ensure that the common stress of two opposite side of steel pipe column, improves shearing resistance and the anti-bending bearing capacity of steel core concrete column, makes peripheral steel pipe
It is capable of the internal oblique steel core concrete column of putting more energy into of one kind of fully collaborative work with concrete；Can strengthen to coagulation in steel pipe column
Relative sliding between the effect of contraction of soil, reduction steel pipe and concrete, strengthens concrete filled steel tube columns bearing capacity.
The present invention solves its technical problem and is adopted the technical scheme that: this kind of oblique concrete filled steel tube of putting more energy into of internal band
Post, including peripheral steel pipe, peripheral steel pipe inner wall be provided with diagonally disposed for putting more energy into of drawknot effect is played to two opposite side of steel pipe,
It is filled with concrete in peripheral steel pipe.
Further, described putting more energy into is put more energy into for steel plate, and described steel plate is put more energy into along steel pipe short transverse arrangement.
Further, described put more energy into be provided with multiple, multiple put more energy into end to end be continuously crisscross arranged, each two ends put more energy into
All fix with peripheral steel pipe inner wall.
Further, described putting more energy into has two rows, and often row puts more energy into connect from beginning to end and is continuously crisscross arranged, and two rows put more energy into corresponding staggered
Arrangement, described putting more energy into is welded and fixed with peripheral steel pipe inner wall.
Further, described periphery steel pipe transverse rectangular cross-section.
Further, described periphery steel pipe include multiple, multiple periphery steel pipe combination and combine lateral cross section be different
Shape.
Further, described abnormity is t type or cross or l type.
Further, described periphery steel pipe include multiple, and multiple periphery steel pipe is in a row is disposed adjacent to each other.
To sum up, the having the beneficial effect that of the technique scheme of the present invention:
1st, concrete filled steel tube column section may be designed as rectangle or the odd-shaped cross section of multiple rectangle composition, meets building requirements,
Abundant cross sectional shape, during using special-shaped steel pipe concrete post, the pillar corner angle that interior is not exposed, improve space and utilize
Rate, makes bean column node design simple simultaneously.
2nd, effectively limit steel pipe and local buckling occurs.It is welded in the diagonally disposed steel plate of peripheral steel pipe inner wall to have put more energy into drawknot
Effect, can effectively prevent peripheral steel pipe walls from outer flexing occurring.
3rd, peripheral steel pipe and the abundant collaborative work of concrete are made.Diagonally disposed putting more energy into enhances between steel pipe and concrete
Interaction, strengthen the effect of contraction to core concrete, make steel pipe and concrete become an overall work.
4th, improve the shear-carrying capacity of steel core concrete column.The diagonally disposed steel plate being welded in peripheral steel pipe inner wall is put more energy into
Certain shear-carrying capacity can be provided when steel core concrete column bears lateral load effect, also can transmit horizontal shear simultaneously,
Enable both sides steel pipe walls collaborative work, jointly resist horizontal loading.
5th, bean column node design is simple.Peripheral outer wall of steel pipe is plane, and welded end plate can be facilitated to be connected with beam.
