Abstract
The utility model relates to a steel truss or a steel grid frame rod connection spherical cap node. The bolted spherical node used currently has certain limitation and can not be used when the cross section of the connected rod is larger. When hollow spherical node is welded, many rods which intersect and have larger cross sections at a same node exist, and the diameter of the required welding sphere is larger, the appearance effect of the building is affected and simultaneously a larger clearance between the surrounding protection structure of the building roof and the steel structure. When many rods which intersect with one another at a same node are provided and the separation angle between one another is smaller, the partial welding is difficult, many superposed part of the welding seams in a same area is more and the quality is hard to control. The utility model is characterized in that: the steel structure spherical cap node comprises a hollow sphere body and a cover plate; the hollow sphere body is of a spherical cap shape; and a cover plate is provided on the upper end for forming a spherical cap connection node. The steel structure spherical cap node provided by the utility model ensures the reliable connection of all rods when many rods which intersect at a same node exist. The steel structure spherical cap node furthermore has the advantages of reliable force transferring, large bearing force, strong versatility, beautiful appearance, convenient installation and ensured quality.
Description
Technical field
The utility model belongs to the structural steelwork technical field, relates to a kind of steel truss or steel mesh hack lever spare and connects the spherical crown node.
Technical background
The joint form that steel structure net rack, truss member connect mainly contains following several types, plate hinged joint, bolted spherical node, welded hollow spherical joints, tubular joint.
The plate hinged joint mainly is applicable to shaped steel (angle steel, channel-section steel etc.) as truss or rod member for grid, be applied in the industrial construction more, as steel-structure factory building, storehouse etc., because structure outward appearance architectural effect is poor, therefore in modern large public building structural steelwork, seldom adopt.
Bolted spherical node mainly is applicable to and by high-strength bolt rod member for grid is linked to each other with solid steel ball in the steel grid structure to have the many characteristics of rod member quantity aesthetic in appearance, that connect.This kind joint form has certain limitation, can't adopt when the bar cross section that is connected is big, therefore can't be applied in the long-span steel pipe trussed construction.
Welded hollow spherical joints is primarily aimed in the long-span steel pipe trussed construction, when the rod member that intersects at same node is to guarantee that all rod members reliably connect more for a long time, hollow ball is set at the node place, and all rod members all are welded on the hollow ball.Have that power transmission is reliable, bearing capacity is big, the characteristics of highly versatile, but needed welding sphere diameter was very big when more and bar cross section was big when the rod member that intersects at same node, influenced the architectural appearance effect and caused the space between building roof space enclosing structure and steel work very big simultaneously.
Tubular joint is a kind of joint form of more employing in recent years, be mainly used in the long-span steel pipe trussed construction, not additional other members at the node place, thinner rod member is directly welded on the thicker mobile jib spare, has good architectural appearance effect, when the more and mutual angle of the rod member that intersects at same node hour can cause very difficulty of local welding, overlapping more at the same area weld seam, difficult quality control.
The utility model content
Technical problem to be solved in the utility model provides that a kind of power transmission is reliable, bearing capacity is big, highly versatile, steel work spherical crown node aesthetic in appearance.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
Special character of the present utility model is: comprise hollow ball, cover plate, hollow ball is a ball crown type, and its upper end is provided with cover plate, constitutes the ball crown type connected node.
Be provided with stiffening rib in the above-mentioned hollow ball.
Above-mentioned cover plate adopts circular steel plate.
Be provided with the gap between above-mentioned cover plate and truss member.
Compared with prior art, the utility model guaranteed when the rod member that intersect at same node more for a long time all rod members can both reliably connect, power transmission is reliable, bearing capacity is big, highly versatile, aesthetic in appearance, conveniently installs and ensures the quality of products; Adopt simultaneously the ball crown type spheroid overcome the big building appearance effect of whole spheroid volume difference shortcoming.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembling drawing of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises hollow ball 1, cover plate 2, and hollow ball 1 is a ball crown type, and its upper end is provided with cover plate 2, constitutes the ball crown type connected node.
Referring to Fig. 2, the size of hollow ball 1 determines according to the radical of phase link member and diameter, must guarantee that all rod members all can reliably be welded on the hollow ball 1 and do not interfere, and the weld gap of assurance minimum simultaneously is to guarantee welding quality; Determine according to the stressed size of rod member the wall thickness of hollow ball 1 reaches whether needs are provided with interior stiffener, hollow ball 1 unnecessary part cuts the formation ball crown type, the cover plate 2 of circular steel plate is adopted in welding simultaneously, must guarantee that cover plate 2 and hollow ball 1 edge reliably weld, 3 of cover plate and truss members should be reserved certain interval and guarantee that weld seam does not overlap to guarantee welding quality.
