Description

Compound concrete filled steel tube outer ring plate beam-column connection
Technical field
The utility model belongs to structural engineering technical field, and particularly the connecting joint structure of a kind of compound concrete-filled tubular column and girder steel designs.
Background technology
Compound concrete-filled tubular column fire resistance is superior, and anti-seismic performance is strong and can not consider limit value of axial compression ratio in designing, and be a kind of form of structure of worth development, be a kind of form of structure with application prospect concerning large span public building and middle-high building.One of key difficulties applying compound concrete-filled tubular column is the connectivity problem solving itself and beam and slab structure, only has the solution of its node problems that compound encased structures just can be made to be developed faster.Concrete-filled tubular connections obtains research and practice application widely in decades, and the domestic and international pertinent literature report of compound concrete filled steel tube steel beam joint seldom.The utility model is the relevant more ripe achievement in research based on Concrete-filled tubular connections, and relate to the steel beam joint connected mode meeting modern structure designing requirement, the engineer applied that can be compound encased structures lays the foundation.
Utility model content
The utility model object is the deficiency existed for prior art, utilizes the technical characterstic of existing conventional steel concrete column and steel beam connecting joint, provides a kind of compound concrete filled steel tube outer ring plate beam-column connection.Node globality of the present utility model is strong, excellent in mechanical performance, simultaneously simplicity of design, easily manufactured and cost is low.
Compound concrete filled steel tube outer ring plate beam-column connection of the present utility model, is made up of compound concrete-filled tubular column, girder steel and Force transmission parts, and described compound concrete-filled tubular column comprises outer steel pipe 1, interior steel pipe 2 and the inner concrete 3 poured into; Described girder steel 4 comprises bottom flange and web; Described Force transmission parts is made up of outer ring plate 5 and anchoring web 6; It is characterized in that, outside outer wall of steel pipe is welded with a circle outer ring plate 5, be connected with bottom flange butt weld on girder steel.Meanwhile, weld vertical anchoring web 6 between outer and inner tube, be embedded in concrete 3, position is just corresponding to the web of the girder steel 4 of vertical lateral arrangement; Outer steel pipe fluting, the part that anchoring web stretches out outer steel pipe is connected with outer ring plate 5 twin fillet wolt up and down, adopts high-strength bolt 8 and girder steel 4 web bolt-weld joint laterally through vertical junction plate 7.For power transmission is clearer and more definite, anchoring web 6 is up and down all higher than girder steel 4 web between outer and inner tube, and the part of stretching out outer steel pipe is contour with girder steel 4 web.The shearing of node area relies on outer steel pipe walls, node area core concrete and anchoring web jointly to transmit; Pulling force suffered by steel beam flange is delivered to outer steel pipe web by outer ring plate, by anchoring web, load is passed to joint cores again.
Described compound concrete-filled tubular column is the section form of inner circle foreign side or Nei Fang foreign side or the outer rectangle of interior rectangle.Described girder steel is steel I-beam or box steel beam.Described concrete is ordinary concrete or high-strength concrete or self-compacting concrete.The octagon ring flat-plate of described outer ring plate to be hypotenuse be straight line or camber line.
Beneficial effect:
1, the utility model is specially adapted to building structure compound concrete filled steel tube center pillar situation, this novel compound concrete-filled tubular column and girder steel outer ring plate connected node, the existence of outer ring plate inherits the simple feature of connection of self and beam, effectively can transmit pulling force and the pressure of bottom flange on girder steel; Anchoring web effectively can improve the Rigidity and strength of node.This joint structure is simple, processes easy for installation, and power transmission is clearly reliable, is conducive to the application of compound encased structures.
2, the utility model is easy to realize strong column and weak beam, purpose of design that node is stronger.Can adapt to modern industrialization Production requirement, particularly along with the operation of cold-formed thin-walled steel pipe large-scale production line and the development of steel structure of housing, advantage of the present utility model will better be played.

Fig. 2 is compound concrete filled steel tube outer ring plate beam-column connection floor map;
Fig. 3 is the I-I generalized section of Fig. 2 interior joint.
Detailed description of the invention
With reference to the accompanying drawings the utility model is described in detail.
The utility model is made up of compound concrete-filled tubular column, girder steel and Force transmission parts.Compound concrete-filled tubular column comprises outer steel pipe 1, interior steel pipe 2 and the inner concrete 3 poured into, and is illustrated in figure 1 inner circle foreign side compound concrete-filled tubular column cross section.
As shown in Fig. 2-Fig. 3, compound concrete-filled tubular column comprises outer steel pipe 1, interior steel pipe 2 and the inner concrete 3 poured into; Girder steel 4 comprises bottom flange and web; Described Force transmission parts is made up of outer ring plate 5 and anchoring web 6; Outside steel pipe 1 outer wall is welded with a circle outer ring plate 5, is connected with bottom flange butt weld on girder steel 4.Meanwhile, weld vertical anchoring web 6 and be embedded in concrete 3 between outer and inner tube, position is just corresponding to the web of the girder steel 4 of vertical lateral arrangement; Outer steel pipe fluting, the part that anchoring web 6 stretches out outer steel pipe is connected with outer ring plate 5 twin fillet wolt up and down, adopts high-strength bolt 8 and girder steel 4 web bolt-weld joint laterally through vertical junction plate 7.As shown in Figure 2, outer ring plate hypotenuse adopts camber line can reach prevention stress and concentrates the feature with good looking appearance, and outer ring plate also can directly adopt skew lines to reach the effect of constructability; As shown in Figure 3, for power transmission is clearer and more definite, anchoring web 6 is up and down all higher than girder steel 4 web between outer and inner tube, and the part of stretching out outer steel pipe is contour with girder steel 4 web.The shearing of node area relies on outer steel pipe walls, node area core concrete and anchoring web jointly to transmit; Axle power suffered by steel beam flange is delivered to outer steel pipe web by outer ring plate, by anchoring web, load is passed to joint cores again.
The compound concrete-filled tubular column that the utility model relates to can be adopted as the section form of the outer rectangle of inner circle foreign side or Nei Fang foreign side or interior rectangle; Interior steel pipe and outer steel pipe can adopt thin-wall steel tube; Girder steel can be steel I-beam or box steel beam; Concrete can be ordinary concrete, high-strength concrete or self-compacting concrete; The octagon ring flat-plate of outer ring plate to be hypotenuse be straight line or camber line.Described realize the Force transmission parts that compound concrete-filled tubular column and steel beam joint just connect and comprise outer ring plate and anchoring web, the node force transfer system that their actings in conjunction are formed, can ensure that node power transmission is complete, reach the object of rigid joint, also can guarantee integrally-built stability.
