Abstract
A hollow interlayer steel tube concrete column and steel beam falling type half-through core node relates to building node constitution. The falling type installation of a steel frame beam is that the steel frame beam is connected to an inner steel tube and an external steel tube separately by welding to transfer force and bending moment. Round-in-round, square-in-round, round-in-square, square-in-square, rectangle-in-rectangle, square-in-rectangle and round-in rectangle hollow interlayer steel tube concrete may be employed, the steels may be common strength steels or high-strength steels, the concrete may be common concrete or high-strength concrete and self-dense concrete, and a thin-wall steel tube may be employed. The inner steel tube is not weakened, it is suitable for condition that the diameter of the inner steel tube is small; the constitution is convenient to manufacture and is suitable for mechanized production; field construction is simple, and installation is convenient.
Description
Technical field
The utility model relates to a kind of building joint structure, particularly relates to the dropping semi-core-through joint of a kind of concrete-filled double skin steel tube post and girder steel.
Background technology
Concrete-filled double skin steel tube is a kind of fill concrete in the interlayer of two-layer steel pipe and the novel steel tube concrete structure that forms.Can be divided into circle cover circle, side's cover circle, circle cover side, cover side, side, rectangular sleeve rectangle, square sleeve rectangle and circular cover rectangular hollow interlayer steel tube concrete by section form, its steel can adopt regular tenacity steel or the yield strength high-strength steel more than 550MPa, concrete can be ordinary concrete or compressive strength high-strength concrete and the self-compacting concrete at 80-120MPa, and can to adopt the steel pipe external diameter (length of side) and the ratio of wall thickness be the thin-wall steel tube of 40-150.Compare with traditional encased structures, this form of structure especially can reduce dead load and improve the bending rigidity of structure, has a good application prospect.And in application process, must relate to concrete-filled double skin steel tube post and the connected node problem of using more steel-frame beam at present, the utility model proposes the dropping semi-core-through connected node of a kind of concrete-filled double skin steel tube post and steel-frame beam.
Summary of the invention
The purpose of this utility model is to provide a kind of half punching connected node that is used for concrete-filled double skin steel tube post and steel-frame beam.It is connected to interior steel pipe, outer steel pipe and transmission power and moment of flexure between Vierendeel girder and two steel pipes by weld seam with steel-frame beam.
Advantage of the present utility model and effect are:
1. steel pipe does not have weakening in the utility model, the less situation of diameter of steel tube in being suitable for.
2. the utility model is convenient to make, is suitable for mechanization production, is reduced the site operation workload; Site operation is simple, easy for installation.
3. the utility model has avoided only being born by outer steel pipe the unfavorable situation of power and moment of flexure, establishes enforced loop plane between steel pipe and the steel-frame beam outside, increases effective usage space.
Description of drawings
Accompanying drawing is an example with the steel-frame beam falling type node of circle cover circle concrete-filled double skin steel tube and H tee section.
Fig. 1,2 and 3 is respectively the schematic diagram of the interior steel pipe that finishes in factory-prepared, outer steel pipe and steel-frame beam;
The whole elevation of node that Fig. 4 finishes for constructing at the scene;
Fig. 5 is the final form floor map of node;
Fig. 6 is the final form generalized section of node.
The specific embodiment
With reference to the accompanying drawings the utility model is elaborated.
As depicted in figs. 1 and 2, by steel pipe 1 and outer steel pipe 3 in the design size processing; By design attitude outside an end of steel pipe 3 open rectangular opening 2, its size is slightly larger than the size of steel-frame beam cross section (still should count the 4a thickness of edge of a wing stiffening plate), the number in hole is determined by the number of the steel-frame beam that will connect.
As shown in Figure 3, by designing requirement machined steel Vierendeel girder 4, simultaneously for guaranteeing that enough edge of a wing sectional areas are with effective transmission moment of flexure, locate each welded flange stiffening plate 4a on the upper and lower edge of a wing of beam-ends, when steel-frame beam frange plate broad influences concrete pouring quality, the upper and lower edge of a wing perforate 5 of the steel-frame beam between inside and outside steel pipe, the shape in hole is advisable to avoid stress to concentrate with circle or ellipse, and number is decided on actual conditions.
As shown in Figure 4,, adopt welding 6 or other connected mode that interior steel pipe 1, outer steel pipe 3 are connected on the base plate 7, guarantee that the concentric and outer steel pipe position of opening of inside and outside steel pipe, direction are corresponding one by one with beam for the first floor; For other layer, adopt welding 6 that interior steel pipe 1, outer steel pipe 3 are welded on the interior steel pipe 1, outer steel pipe 3 of lower floor, guarantee that the concentric and outer steel pipe position of opening of inside and outside steel pipe, direction are corresponding one by one with beam.
As Fig. 5, shown in Figure 6, treat that post installs after, steel-frame beam 4 is fallen to being installed in the hole 2 of outer steel pipe, the upper and lower edge of a wing and web with adopt groove weld 9 welding being connected of interior steel pipe, the upper and lower edge of a wing is connected employing fillet weld 8 and welds with outer steel pipe; Solder up plate 4b then; Concreting 10 between outer and inner tube at last, the concrete height should be a little less than the top of steel pipe, so that connect the last layer steel pipe.
Step of the present utility model and process conditions are:
The first step: by steel pipe, outer steel pipe in the design size processing; By design attitude outside steel pipe one end open rectangular opening;
Second step: by designing requirement machined steel Vierendeel girder;
The 3rd step: adopt welding or other connected mode that interior steel pipe, outer steel pipe are connected on the interior steel pipe of base plate or lower floor, the outer steel pipe at the construction field (site), guarantee that the concentric and outer steel pipe position of opening of inside and outside steel pipe, direction are corresponding one by one with beam;
The 4th step: steel-frame beam is fallen to being installed in the rectangular opening of outer steel pipe; The upper and lower edge of a wing is adopted groove weld, the upper and lower edge of a wing to be connected with outer steel pipe with web and being connected of interior steel pipe and is adopted fillet weld; Solder up plate then;
The 5th the step: after every layer of beam column installs between inside and outside steel pipe concreting.
Steel pipe and outer steel pipe in the utility model is connected to steel-frame beam by weld seam are by weld seam transmission power and moment of flexure between Vierendeel girder and two steel pipes.Can adopt circle cover circle, side's cover circle, circle cover side, cover side, side, rectangular sleeve rectangle, square sleeve rectangle and circular cover rectangular hollow interlayer steel tube concrete, its steel can adopt regular tenacity steel or high-strength steel, concrete can be ordinary concrete or high-strength concrete and self-compacting concrete, and can adopt thin-wall steel tube.The utility model does not have weakening for interior steel pipe, the less situation of diameter of steel tube in being suitable for; Be convenient to make, be suitable for mechanization production; Site operation is simple, easy for installation; Avoided only bearing the unfavorable situation of power and moment of flexure, established enforced loop plane between steel pipe and the steel-frame beam outside, increased effective usage space by outer steel pipe.
