Description
Technical field
The present invention relates to a kind of assembly concrete-filled steel tube post post connected mode, belong to technical field of structural engineering.
Background technology
Assembling type steel structure system refers to the building subassembly specification making house unit or component according to unified, standard, so
The building that job site assembling is produced in place is transported to afterwards.It is characterized in that construction quality light, energy-conserving and environment-protective, speed of application be fast, work
Industry degree height etc., can solve that China's building industrialization level is low, house building labor productivity is low and conventional house product
The low problems of quality, adapt to the development of China's building trade.
Post post connected mode is important connected mode in assembling type steel structure system, and it directly affects the construction of structure
Speed and assembling degree, thus post post connected mode should try one's best it is many using be easy to by the way of operating and its bearing capacity not
There can be more obvious reduction.The post post connected mode used in existing case history has the following disadvantages：
Traditional pillar joint connection manner with weld or bolt connection based on.
Solder design has the following disadvantages.(l) influenceed (2) weld seam easily to there are various defects by high temperature when welding to weld
Base metal near seam is easily caused material and become fragile.Thus cause to produce stress concentration in component and expand crackle.(3) due to
Welded rigidity is big, and the localized crackses existed individually easily expand to entirety.Above once referred to that particularly welding structure was easy
Generation brittle fracture under low temperature phenomenon, is exactly this reason.(4) after welding, ununiform shrinkage during due to cooling there will be weldering in component
Residual stress is connect, partial cross section during component load-bearing can be made to enter plasticity in advance, the Critical Stability stress of component when reduction is pressurized.
(5) after welding, component is produced welding residual deformation due to uneven breathing, such as make to be that concavo-convex become occurs for the steel plate of plane originally
Shape etc..
Bolt connection is divided into two kinds of plain bolt connection and high strength exploitation.Plain bolt connecting bolt precision is low
When, it should not be cut, processing and installation difficulty are larger when bolt precision is high.Rubbing surface handles mounting process during high strength exploitation
Slightly complicated, cost is slightly higher, and is easily loosened under dynamic action.
The content of the invention
The present invention proposes a kind of assembly concrete-filled steel tube post post connected mode, can effectively solve job site upper prop with
Orientation problem when lower prop is connected；Partial component can weld completion in factory, improve the assembled speed at scene.
The present invention proposes a kind of assembly concrete-filled steel tube post post connected mode, and its object is to overcome prior art
Defect and the every mechanical property for meeting node, realize that post Column border node is rigidly connected, and realize the intermodule assembling of structure, improve
The assembled speed of component, fully adapts to requirement and the feature of assembling type steel structure system.
Technical scheme is as follows：
A kind of assembly concrete-filled steel tube post post connected mode, it is characterised in that：The attachment means include
Lower prop (1), upper prop (2), inner panel (3) and upper prop bolt (4)；
The bolt hole of the inner panel (3) has the screw thread matched with upper prop bolt (4)；
Each lower prop (1) is connected with four inner panel (3) plug weldings, and inner panel (3) is welded in down
The cross-sectional internal of post (1), and be connected with upper prop (2) by upper prop bolt (4)；
The lower prop (1) connects and composes component A2 with inner panel (3) plug welding；
Described upper prop (2) and lower prop (1) have identical cross-sectional form；The cross section vertical axis of lower prop (1) with
The cross section vertical axis alignment of upper prop (2), lifts to pour after column interior at the construction field (site) and fills up concrete, so that in post
Son is internally formed armored concrete.
When inner panel (3) is not provided with screw thread, the interior crab bolt matched with upper prop bolt (4) is also welded with inner panel (3)
(5), inner panel (3) and interior crab bolt (5) are in the integrally welded member of formation A1 of factory.
Beneficial effect
The post post attachment means of the present invention carry out assembled in situ using lifting, and the inner panel welded with lower prop was lifted in upper prop
Play a part of the booster action that inner panel after the completion of positioning, lifting plays node region in journey.By in pillar after the completion of lifting
Pour and fill up concrete.Column interior casting concrete realizes the connection of some strength, and the connecting portion of pillar is located at inflection point
Near, therefore casting concrete can lift the shear resistance of pillar.Lower prop and inner panel and inner panel nut-welding are integral or interior
There is the screw thread matched with bolt in crab bolt hole, the nut matched instead of bolt, makes between upper prop and lower prop by upper prop spiral shell
Bolt is connected, and realizes being rigidly connected for post Column border node, and realizes the intermodule assembling of structure, improves the assembled speed and matter of component
Amount, fully adapts to requirement and the feature of assembling type steel structure system.The assembly concrete-filled steel tube post post connected mode makes construction
Speed and quality are greatly improved, and adapt to the development of assembling type steel structure.
