Description
Technical field
The utility model is related to assembled architecture technical fields, are specifically one kind and wear muscle assembly concrete-filled steel tube-H-shaped
Steel beam joint system.
Background technology
At present, China is just carrying forward vigorously assembled architecture development, and assembled method of construction can reduce construction to ambient enviroment
Destruction, reduce to the interference of periphery traffic, save building time, assembled architecture is conducive to that engineering structure is extensive, mark
Quasi- metaplasia production, is conducive to construction quality management and control.The fabricated construction of Current Domestic application is chiefly used in multilayer or small high-rise is prefabricated
Framed building, using still less in high-rise, high-rise building.And the research spininess of current fabricated construction is to armored concrete
Structure, it is less to the assembling implementation of steel-mixed combining structure.Concrete filled steel tube is used as high-rise and high-rise building
One of primary structure form, realize its assembling based on its construction features, be conducive to assembled mode of construction to high-rise and super
Skyscraper is promoted.
Concrete filled steel tube Vierendeel girder is typically girder steel, for the connecting node of girder steel and steel core concrete column, according to
Beam column correlativity can be divided into that column is through and through two kinds of girder steel.Compared with column penetration type node, beam through type more holds
Easily realize the design of node of " rigidity ", and beam through type node steel using amount is few, the use of large-size steel pipe also weakens girder steel
Through brought with interior stiffener ring plate concrete cast and vibrate inconvenience the problem of.Beam through-type tubular joint mainly has beam integrally to run through
Formula, edge of a wing penetration type, web penetration type.Beam entirety penetration type node punches in steel pipe walls flange of beam and web correspondence position, steel
Beam is whole by piercing steel core concrete column, and such node guarantee globality of beam is conducive to the transmission of power between beam column, ensures
The geometry globality of beam avoids beam stress raisers, and overall stiffness is larger and bearing capacity is higher, and anti-seismic performance is good.
But steel pipe walls punch it is larger to the weakening of column, girder steel it is multidirectional it is intersecting processing it is more difficult.Edge of a wing penetration type node refers to that tube wall exists
Steel beam flange correspondence position punches, and the edge of a wing is then welded on by piercing steel core concrete column, web on the outside of tube wall.It is passed through compared to whole
Formula is worn, can preferably ensure the transmission of moment of flexure and shearing, while the reduction to punch improves the weakening to tube wall.Web runs through
Formula node refers to that tube wall punches in steel beam web plate correspondence position, and web was then welded on pipe by piercing steel core concrete column, the edge of a wing
On the outside of wall.Compared to whole penetration type, moment of flexure transmission capacity is poor, the easily cracking destruction of edge of a wing weld seam, but without the wing in pipe
Edge passes through the influence for pouring and vibrating improved to core concrete.
It realizes the assembling of concrete filled steel tube, gives full play to beam and wear formula node mechanical characteristic, to promote steel tube concrete
Application of the soil structure in fabricated construction.

It boxes out hole, steel beam flange plate is inserted by reserving hole inside steel pipe one, and vertical muscle is located in steel pipe one, is indulged muscle and is run through steel beam flange
Reserving hole arrangement on plate；Steel core concrete column mainly includes steel pipe two；Two internal upper part of steel pipe blocks for concrete dense, middle part
Vertical muscle connecting cavity is formed for concrete column, between concrete column and steel pipe two；Vertical muscle is arranged in vertical muscle connecting cavity, lower part tool
There is concrete jag.
The utility model has the advantages that：
1st, reasonably optimizing nodes domains beams-column stress relation sets preformed hole by steel pipe, and steel beam flange directly anchors core
It in heart concrete, avoids steel pipe and bears pulling force, make steel pipe more effectively restraint joint domain core concrete.Simultaneously because of the girder steel wing
Edge non-fully through cylinder, offers convenience for core concreting in prefabrication process.
2nd, by setting longitudinal reinforcement inside nodes domains core concrete, on the one hand to go deep into the girder steel of core concrete
The edge of a wing provides anchoring, on the other hand makes up the cylinder bending bearing capacity caused by steel pipe perforate and declines, meanwhile, extend core
The reinforcing bar of heart concrete end face is provided convenience for the connection of node component and cylinder.
3rd, based on concrete filled steel tube feature, by rationally designing the relative position of steel pipe and core concrete, realize
The bayonet joint of node component and cylinder, convenient for the precision and quality of connection of control connection.
