Abstract
The invention discloses prestressing force cable body anchorage ball node, it is characterized in that: two pieces of plane steel plates are made two hemispherical Shells, edge at two hemispherical Shells, radially symmetry offers notch, two hemispherical Shells the most mutually fasten with notch, weld between the hemispherical Shell of two mutual fastenings, it is formed at the spherical shell on radial symmetric position with pair of openings, otic placode runs through pair of openings jointly, and protrude out formation engaging lug in the side of spherical shell, otic placode is fixing with spherical shell at aperture position to be welded, and each pipe fitting is fixedly welded on the surface of spherical shell and forms ball node.The present invention solves drag-line and the connectivity problem of rigid structure in prestressed steel structure, improves the stress performance of cable body anchorage ball node, improves construction quality.
Description
Technical field
The present invention relates to a kind of cable body anchorage ball node applied in drag-line prestressed steel structure.
Background technology
Along with the development of building industry, version is various and changeful steel construction be increasingly widely applied with
Development, including prestressing force slant-pull structure.In prestressing force slant-pull structure, drag-line and rigid structure are attached playing work
With, drag-line is force part extremely crucial in total with the node of rigid structure junction, is directly connected to whole knot
The safety of structure, therefore the making to ball node proposes the highest requirement.Traditional fabrication mode is: the two heated pressures of block plate
System forms two hemispherical shells, then the butt welding that interlocked by two hemispherical shells prepares the hollow ball node that surface is complete, this
Hollow ball node surface is complete, but must weld otic placode on hollow ball node or weld other form component, in order to for drawing
Rope provides stress point, the problem that surface soldered otic placode inevitably brings following each side:
One, the junction at otic placode Yu hollow ball node is formed with stress concentration, is unfavorable for structure stress；
Two, otic placode is difficult to be accurately positioned on hollow ball node surface, and welding quality is difficult to ensure that.
Summary of the invention
The present invention is for avoiding the deficiency existing for above-mentioned prior art, it is provided that a kind of prestressing force cable body anchorage ball node,
Effectively solve drag-line and the connectivity problem of rigid structure in prestressed steel structure, improve the stress performance of cable body anchorage ball node,
Reduce labor strength, improve construction quality.
The present invention solves that technical problem adopts the following technical scheme that
Being structurally characterized in that of prestressing force cable body anchorage ball node of the present invention: two pieces of plane steel plates are made two hemispherical Shells,
In the edge of two hemispherical Shells, radially symmetry offers notch, and two hemispherical Shells the most mutually fasten with notch, at two
Welding between the hemispherical Shell mutually fastened, be formed at the spherical shell on radial symmetric position with pair of openings, otic placode is common
Running through pair of openings, and protrude out formation engaging lug in the side of spherical shell, described otic placode is fixing with spherical shell at aperture position to be welded,
Each pipe fitting is fixedly welded on the surface of described spherical shell and forms ball node.
The construction features of prestressing force cable body anchorage ball node of the present invention lies also in: described opening is set to slope at dual-side
Mouthful, form the weld seam between otic placode and spherical shell with uncovered outside groove.
Compared with the prior art, the present invention has the beneficial effect that:
1, otic placode is welded in the opening of spherical shell by the present invention, makes joints more single, decreases moment of flexure and shearing,
Stress performance is more excellent.
2, otic placode accurate positioning in the present invention, can guarantee that welding quality.
3, opening is set to groove by the present invention, forms weld seam, make welding job simpler in groove, welding jail
Gu, and make ball node surface whole add smooth.
Accompanying drawing illustrates:
Fig. 1 is present configuration schematic diagram；
Fig. 2 is spherical shell sectional structure schematic diagram in the present invention；
Fig. 3 is spherical shell sectional structure schematic diagram in the present invention；
Label in figure: 11 otic placodes, 12 pipe fittings, 13 drag-lines, 20 hemispherical Shells, 21 openings, 22 weld seams.
Detailed description of the invention
Seeing Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, the version of prestressing force cable body anchorage ball node is: put down two pieces
Two hemispherical Shells 20 made by face steel plate, and in the edge of two hemispherical Shells 20, radially symmetry offers notch, two hemispherical Shells
20 the most mutually fasten with notch, weld between the hemispherical Shell 20 of two mutual fastenings, are formed at radial symmetric position
On there is the spherical shell of pair of openings 21, otic placode 11 runs through pair of openings 21, and protrudes out formation engaging lug, otic placode in the side of spherical shell
11 fixing with spherical shell at aperture position welds, and each pipe fitting 12 is fixedly welded on the surface of spherical shell and forms ball node, engaging lug use
Bolt or pin joint in the end with drag-line 13.
In being embodied as, in order to ensure welding quality, opening 21 is set to groove at dual-side, with uncovered outside slope
Weld seam 22 between interruption-forming otic placode 11 and spherical shell.
The present invention utilize otic placode realize being connected between ball node with drag-line so that each pipe fitting in tubular truss and ball
Realize between node arbitrarily passing through mutually, decrease welding job, make ball node obtain more preferable reliability and higher stability.
