The forms such as point, sliding node, that there is structural strengths is low for above-mentioned node, and site operation difficulty is big, is not suitable for the rack of large span
Therefore the disadvantages of structure, from construction period and steel construction characteristic, needs more particularly suitable support node to realize.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of hemispherical steel structure support node,
The structure is simple, structure safety, versatile, and site operation assembly is simple, and overall structure is firm, is widely applied rack knot
The support node of structure.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of hemispherical steel structure support node,
For connecting upper building and lower part building, including shelly-shaped steel hemisphere and several round tubes being welded on shelly-shaped steel hemisphere
Column, cross semi-circular sheet steel is welded in the cavity of the shelly-shaped steel hemisphere, and short steel pipes, short steel pipes are welded in shelly-shaped steel hemisphere bottom
Weld bottom anchor slab in bottom.
Further, tubular pillar as described above is welded to connect upper building, and bottom anchor slab connects lower part building.
Further, intersecting mouth is machined on shelly-shaped steel hemisphere and tubular pillar as described above and formed at intersecting mouth
Weld seam.
Further, cross semi-circular sheet steel as described above is by the positive aspect vertical welding quadrant of semi-circular sheet steel
Shape steel plate forms.
Further, cross semi-circular sheet steel as described above by four blocks of a quarter circle steel plates around its radius according to four
Circumference in equal parts is welded.
Further, several through-holes are offered on bottom anchor slab as described above.
Further, bottom anchor slab as described above is with welding for steel structure and steel construction is poured mixed mud.
Compared with prior art, the utility model has the beneficial effects that the present apparatus is the hemispherical branch for grid structure
Node is supportted, structure is clear, and stress is simple, there are enough strength and stiffness, not prior to rod piece and other nodes under load action
And destroy, the deformation that can not ignore will not be generated.Support node is formed by steel hollow ball with steel-pipe welding, spherical surface and round tube
When part connects, round tube part need to only be cut off along normal section, simple for production, construction and installation are convenient, are widely used in various sport
In the grid structures in places such as shop, amusement venue.
