Description

A kind of concrete-filled rectangular steel tube hetermorphiscal column and steel girder frame corner node
Technical field
The utility model relates to building concrete-filled steel tubular frame node, particularly a kind of concrete-filled rectangular steel tube hetermorphiscal column and steel girder frame corner node.
Background technology
The special-shaped column structure system is a kind of new structure system that grows up in China in recent years.The layout of this structural column is very flexible, and post limb and infilled wall uniform thickness can be avoided the stupefied protrusion of indoor-bollard, increase the actual usable floor area in room, thereby receive owner and real estate developer's favor deeply; It can also utilize insulation, heat insulation, lightweight, materials for wall replaces traditional loam brick efficiently, meets the requirement of nation-building conservation-minded society, therefore is popular.Widespread usage is steel concrete (hereinafter to be referred as RC) Framed Structure with Special-Shaped Columns in the current engineering, yet deepens continuously along with what use and study, and these some obvious defects of Structure Beam-column node have limited its scope of application.At first, cross section, bean column node district is less, and when especially post limb thickness was identical with deck-siding, the main steel bar stress of beam and column intersected in same plane, and reinforcement location is difficult for staggering, and causes very big difficulty for cloth muscle and concreting; Secondly at the node place owing to receive the restriction of high length depth ratio of post limb (≤4) and limb thick (being generally less than 250mm), the shear resistant capacity of shaped pile frame node than rectangular column relative thin a little less than, antidetonation and deformation performance are also than rectangular column difference.So the scope of application of present Framed Structure with Special-Shaped Columns is very limited, be only applicable in the multistory building in area below seismic fortification intensity 8 degree.In order to satisfy the great demand in market; Further promote the application of special-shaped column structure; Particularly make it be applicable to highrise building and the building in the high earthquake intensity area of providing fortification against earthquakes in, research and develop out that a kind of reasonable stress, power transmission are clear and definite, simple structure and have higher shear-carrying capacity and the novel shaped pile frame node of good antidetonation and deformation performance has become the task of top priority.
The concrete-filled rectangular steel tube structure is meant penetration concrete in welding or extrusion modling rectangular steel pipe, and this structure node has been given full play to the advantage of steel and two kinds of different materials of concrete, and its shear-carrying capacity and antidetonation and deformation performance all are significantly improved; And in work progress, steel pipe can be used as the template of its core concrete of pouring, therefore can reduce expenses, and accelerates speed of application.Therefore this kind node makes special-shaped column structure in the building in highrise building and high earthquake intensity area, be able to apply.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; The purpose of the utility model is to provide a kind of concrete-filled rectangular steel tube hetermorphiscal column and steel girder frame corner node; Can effectively improve the shear-carrying capacity and the anti-seismic performance of shaped pile frame corner node; Make the special-shaped column structure system in the building of highrise building and highly seismic region, be able to apply, particularly seismic fortification intensity is at the highrise building in 8 degree and above area thereof.
In order to achieve the above object, the technical scheme of the utility model employing is:
A kind of concrete-filled rectangular steel tube hetermorphiscal column and steel girder frame corner node, hetermorphiscal column 7 is made up of the steel pipe 5 of inner concrete perfusion 3, and the cross section of hetermorphiscal column 7 is L shaped, external first i beam 1 of difference and second i beam 2 on two protrusion directions of L shaped cross section.
For further improving supporting capacity and anti-seismic performance; In steel pipe 5, be provided with level and with i beam 1; 2 high upper spacers 6 such as top flange, in steel pipe 5, be provided with level and with the lower clapboard 4 of the height such as bottom flange of i beam 1,2; On said upper spacer 6 and the lower clapboard 4 the concreting hole is set; Upper spacer 6 is established air-vent for 4 four jiaos with lower clapboard, and upper spacer 6 adopts the groove of band backing plate to dissolve entirely in order with the inboard of lower clapboard 4 and steel pipe 5 and is welded to connect thoroughly, and last one side connects with electroslag welding with consumable nozzle.
Steel pipe 5 can be spliced to form through fillet weld by the vertical steel plate of extrusion modling.
Compared with prior art, the beneficial effect of the utility model is:
1) easy construction because steel pipe, internal partition, the girder steel of node area can process in factory and weld together in advance, connects after lifting assigned address, and then whole skeleton can bear load in construction;
2) because there is not the crowded situation of node area reinforcing bar in the interior no-reinforcing-bar of node area;
3) bearing capacity is high; Anti-seismic performance is excellent, and experimental study shows that the energy-dissipating property of this novel joint is 2~3 times of RC shaped pile frame node; Shear resistant capacity also is improved largely, and has promptly reached the shear-carrying capacity that improves common RC shaped pile frame node and the purpose of anti-seismic performance.Make the special-shaped column structure system in the building of highrise building and highly seismic region, be able to apply, particularly at the highrise building in seismic fortification intensity 8 degree and above area thereof.
