Description
Technical field
The utility model relates to a kind of steel core concrete column and outsourcing U-shaped steel-concrete combination beam, especially a kind of steel core concrete column and outsourcing U-shaped steel-concrete combination beam connected node.
Background technology
The vertical member that steel core concrete column refers to fill concrete in steel pipe and formed, have that bearing capacity is high, plasticity and the advantage such as ductility is good, rigidity large, easy construction, fire resistance are good, receive the extensive concern of engineering circles in recent years, more and more applied in multi-rise building, bridge engineering.Different according to section form, steel core concrete column can be divided into concrete-filled circular steel tube column, rectangular steel-tube concrete column and polygon steel pipe concrete column.Outsourcing U-shaped steel-concrete combination beam be steel plate is directly welded or clod wash become band flanging U-shaped steel, then and top flange top concreting inner at U-shaped steel, and U-shaped steel and T section concrete to be linked together shared load by shear connector, have that intensity is high, good stability, ductility are good, refractoriness is good, a superior performance such as convenient of constructing.Thus, the structural system formed by steel core concrete column and outsourcing U-shaped steel-concrete combination beam has following significant superiority:
(1) characteristic of steel, concrete bi-material can be given full play to, material consumption is few: outsourcing U-shaped steel-concrete combination beam and concrete filled steel tube columns bearing capacity is high, rigidity is large, member section is significantly reduced, not only increase effectively space usable floor area, and decrease steel and concrete consumption, effectively reduce the consumption of resource;
(2) suitability for industrialized production degree is high: outsourcing U-shaped steel and steel pipe all can in plant produced, and its mechanization, commercialized degree are higher, and reliable in quality is stablized, and is conducive to realizing the integrated of Building technology and industrialization;
(3) fire resistance strengthens: outsourcing U-shaped steel and the interior concrete of filling of steel pipe are good refractory materials, and Absorbable rod heat, the heating up time of member for prolonging, strengthens the fire resistance of structure;
(4) Energy Consumption of Construction is low, speed of application is fast: primary structure member is not only by outsourcing U-shaped steel and steel pipe, and all can be used as the template of concreting, the supporting of slab form doublely can be done in the top flange that U-shaped steel is overhanging in addition, thus reduce template consumption, scaffold building and a die process, reduce situ wet workload, noise and dust, meet the building operations requirement of green ecological civilization environmental protection;
(5) MAT'L recycling rate is higher: such structural part material is steel, belongs to regrown material, and when Building life cycle end cycle, its structural steel can be recovered utilization;
(6) new materials such as the Light trabs supporting with structural system, composite floor plate can be adopted, there is good sound-insulating performance, meet the requirement of building energy conservation.
As can be seen here, the structural system that steel core concrete column and outsourcing U-shaped steel-concrete combination beam are formed has good Social benefit and economic benefit.Particularly along with the high speed development of the development of the national economy, the popularization of housing industrialization, the application prospect of this green structural system will be very wide.
In structural system, node, concerning most important beyond doubt structure, be the power transmission hinge between structural element, be directly connected to service behaviour and the safety of structure, and rational joint form is the prerequisite of developing new structural systen.But the application example of the structural system also not having outsourcing U-shaped steel-concrete combination beam and steel core concrete column to be formed both at home and abroad at present and correlative study data, mainly because available joint form is very deficient.Therefore, along with deepening continuously of studying component, the rational structure form of research outsourcing U-shaped steel-concrete combination beam and concrete filled steel tube column jointing gusset, is open up, promote the key technology that this green structural system applies in engineering, has important theory significance and practical value.
At present, there is the connected node form of three kinds of steel core concrete columns and outsourcing U-shaped steel-concrete combination beam: (1) enforced loop plane under the steel pipe arranged outside of compound beam base plate position, and with the overlap welding of compound beam base plate, compound beam side plate directly welds with steel pipe walls, and negative reinforcement by punching continuous through node area in steel pipe walls; (2) at the upper and lower enforced loop plane of steel pipe arranged outside of compound beam base plate and wing plate negative reinforcement position, compound beam base plate and lower enforced loop plane overlap welding, negative reinforcement disconnects in node area, and welds with upper enforced loop plane, and compound beam side plate directly welds with steel pipe walls; (3) for wide-flat beam, node welds the hogging moment steel plate of similar " shoulder pole ", at the steel pipe arranged outside outer ring plate of compound beam base plate position, compound beam base plate welds with outer ring plate, top flange and side plate adopt fillet weld to be directly connected with steel pipe walls.

(2) compound beam side plate and steel pipe walls also adopt solder design, further increase on-the-spot welding job amount.The node structure effort of a large amount of welding operation of this need is time-consuming, causes long construction period, is unfavorable for that major works uses.
3, form of structure (3): hogging moment steel plate type
(1) because the hogging moment steel plate of the negative reinforcement in node by similar " shoulder pole " replaces, and on the overhanging top flange that hogging moment steel plate need be welded on U-shaped steel and steel column side wall, therefore, the type node is only applicable to wide-flat beam, cannot be applicable to the outsourcing U-shaped steel-concrete combination beam of common size, the scope of application is very limited.In addition, hogging moment steel plate need be welded on compound beam and steel pipe, further increases on-the-spot welding job amount;
(2) because compound beam side plate and steel pipe walls adopt solder design, Site Welding workload is large, not only requires great effort time-consuming, and weldquality is difficult to ensure, is unfavorable for that major works uses.
