Comprise steel pipe column and be embedded in the inner sleeve in steel pipe column, inner sleeve and steel pipe column connect in place of boundary and are connected together along peripheral weld; Both sides up and down in steel pipe column and steel weld in beam flange weld together inner sleeve, steel pipe column to make inner sleeve, steel pipe column be connected to entirety. The present invention can be ensureing that steel pipe column, outside Nodes is strengthened, also realize the vertical perforation of steel tubular column joints, unobstructed when concrete perfusion in steel pipe column, thereby ensured the packing of steel pipe column inner concrete.
Description
Technical field
The present invention relates to a kind of inner sleeve shape steel tube concrete beam and column node, belong to construction steel structure field. Be mainly used in steel pipe mixedThe connected node of solidifying soil and girder steel.
Background technology
At present, the node that in construction steel structure, steel core concrete column is connected with girder steel generally adopts internal partition formula bean column node[1], forNode is strengthened, and the horizontal steel plate that corresponding girder steel edge of a wing place adds perforate in steel pipe column is conventionally as internal partition, internal partitionWeld with steel pipe column periphery. But this internal partition formula beam-column connection, execute box-type section vial wall both sides inside and outside same positionWeldering, can cause that vial wall becomes fragile, and post jamb likely produces lamellar tearing; When vial wall thickness hour, this kind of internal partition formula beamColumn connected node is made corresponding cumbersome, and welding deformation is larger, operates also more difficult; Meanwhile, after internal partition punches, thoughSo concrete can be built, but the lower angle point concrete leakiness being connected with steel pipe column at internal partition.
(research of [1] concrete-filled rectangular steel tube internal partition formula node shear-carrying capacity, Gao Chunyan, Liu Zhifeng, Li Bin, Inner Mongol sectionSkill college journal, in December, 2008, the 27th volume, the 4th phase, 355-362)
Summary of the invention
In order to overcome, traditional internal partition formula bean column node vial wall becomes fragile, post jamb may produce lamellar tearing, make difficulty and interior everyThe deficiencies such as the lower angle point concrete leakiness that plate is connected with steel pipe column, the invention provides a kind of inner sleeve shape steel tube beam column built from concrete jointPoint.
The technical scheme that technical solution problem of the present invention adopts is: a kind of inner sleeve shape steel tube concrete beam and column node, comprises steelTubing string, also comprises the inner sleeve being embedded in steel pipe column, and inner sleeve and steel pipe column connect in place of boundary and be connected together along peripheral weld; At steelThe both sides up and down of tubing string and steel weld in beam flange weld together inner sleeve, steel pipe column to make inner sleeve, steel pipe column be connected to entirety.
Preferably, on inner sleeve and steel pipe column corresponding to the two sidetracking welding holes up and down of steel pipe column and the upper and lower edge of a wing of girder steel weld seamAfter carry out plug welding.
Preferably, welding hole diameter >=20mm.
The preparation method of above-mentioned inner sleeve shape steel tube concrete beam and column node, by disconnected steel pipe column about 300mm place above bean column nodeOpen, inner sleeve is filled in steel pipe column; By steel pipe column and inner sleeve connecing in place of boundary along periphery welding, after weld seam is cooling,On inner sleeve and steel pipe column corresponding to the two sidetracking welding holes up and down of steel pipe column and the upper and lower edge of a wing of girder steel weld seam, welding hole diameter >=20mm, then carries out plug welding; Butt welded seam completes the making of inner sleeve shape steel tube concrete beam and column node after polishing; ExistingCan be in this node after installing placing concrete smoothly.
Said structure makes inner sleeve and steel pipe column be connected to entirety by weld seam, is able to the object of cooperative bearing and cooperative transformation.
The invention has the beneficial effects as follows, this kind of node overcome the various shortcomings of traditional internal partition formula bean column node, Nodes steel pipePost jamb is only having weld seam with girder steel junction, and weld seam is little to steel pipe column mother metal performance impact, is easy to construction, when casting concrete,Have no occluder in steel pipe column, therefore steel pipe column inner concrete packing promotes greatly, has also ensured inner sleeve and steel pipe column collaborative work.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the graphics of inner sleeve shape steel tube concrete beam and column node.
In figure, 1. steel pipe column, 2. inner sleeve, 3. weld seam, 4. girder steel, 5. girder steel edge of a wing place weld seam, 6. plug welding place.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
As depicted in figs. 1 and 2, inner sleeve shape steel tube concrete beam and column node comprises steel pipe column 1, in steel pipe column has been embedded inSleeve 2, the gap of inner sleeve outer wall and steel pipe column inwall is 3-4mm, makes inner sleeve can fill in smoothly steel pipe column. Inner sleeve and steelTubular pipe connection circle is connected together along peripheral weld in place; In the both sides up and down of steel pipe column and girder steel 4 commissures, the edge of a wing 5 by inner sleeve, steelTubing string welds together makes inner sleeve, steel pipe column be connected to entirety. Preferably inner sleeve and steel pipe column weld adopt plug welding.
Concrete preparation method is: steel pipe column 1 about 300mm place above bean column node is disconnected, inner sleeve 2 is filled in to steel pipe columnIn 1; Steel pipe column 1 and inner sleeve 2 are connected together along peripheral weld connecing in place of boundary, after weld seam is cooling, at inner sleeve and steelOn tubing string, carry out plug welding corresponding to the two sidetracking welding holes up and down of steel pipe column and the upper and lower edge of a wing of girder steel weld seam; The plug welding first designingWelding hole is bored in position 6., diameter >=20mm, and the present embodiment 20mm, carries out plug welding; In butt welded seam 3 completes after polishingThe making of socket type steel tube concrete beam and column node, can be in this node after installing at the scene placing concrete smoothly. Be made intoInner sleeve shape steel tube concrete beam and column node as shown in Figure 2.
Said structure outside Nodes is strengthened, has also been realized the vertical perforation of steel tubular column joints, at steel pipe at guarantee steel pipe columnUnobstructed when concrete perfusion in post, thus the packing of steel pipe column inner concrete ensured.
