Abstract
The utility model discloses a space curved surface gridding cross plate connection node structure, which comprises steel tubes, and is characterized in that: a cross connection plate is involved; two welding end faces with different angles are arranged at a welding end of each steel tube; and four steel tubes are welded to the cross connection plate through the welding end faces to form a space curved surface node structure. Compared with the prior art, the space curved surface gridding cross plate connection node structure has the advantages of simple structure and high adaptability, the processing quality is guaranteed, the construction speed is increased, and the manufacturing cost is reduced.
Description
Technical field
The utility model belongs to a kind of building unit connected node structure, particularly a kind of space curved surface grid four-bladed vane connected node structure.
Background technology
At present; Some large-scale public buildings such as stadiums are because curved surface steel tubular structure system is often adopted in function of use or requirement attractive in appearance; Form the space nodes that multitube intersects; Position of joints bears the internal force that each root rod member transmits, and the stress of node is very complicated, requires to accomplish the weak member of strong node in the design.For this space nodes, generally do not allow to adopt solder sphere or bolted spherical node, two kinds of joint structures are arranged usually; A kind of way is to adopt cast steel member, and pour steel in mould can be made Any shape in theory; Confirm internal structure and wall thickness through finite element analysis or test, for the smaller node of sectional dimension, because tube wall is thinner to shaped; Cast steel quality is difficult for guaranteeing that process velocity is slow that cost is higher.Another kind of way is that many steel pipes weld at the intersection point place; For many rod member crossed nodes, the intersection steel tube section is weakened, if only the steel pipe of intersection is welded mutually; Ultimate bearing capacity of joints has satisfied not designing requirement; Usually need weld measures such as reinforcing ring at the node place, not only welding procedure is complicated, welding quality is difficult for guaranteeing, also influences the attractive in appearance of node.
Summary of the invention
The purpose of the utility model provides a kind of space curved surface grid four-bladed vane connected node structure, and is simple in structure, guarantees crudy, accelerates speed of application, reduces cost, and applicability is strong.
The purpose of the utility model realizes through following technical scheme: it comprises steel pipe; It is characterized in that: the cross junction plate is set; The welding ends of every steel pipe is provided with the welding end surface of two different angles; 4 steel pipes are welded on the cross junction plate through welding end surface, constitute the space curved surface node structure.
The utility model and prior art compare, and its advantage is: simple structure, can guarantee crudy, and accelerate speed of application, reduce cost, applicability is strong.

The specific embodiment
See Fig. 1-5; Concrete structure is following: be provided with the cross junction plate; The cross junction plate is intersected by cross connecting plate 2 and vertical junction plate 3 and constitutes; The welding ends of every steel pipe 1 is provided with the welding end surface of two different angles, and 4 steel pipes are welded on the cross junction plate through welding end surface, constitutes the space curved surface node structure.Vertically the area of junction plate 3 compensates the cross section that node place steel pipe is weakened; Cross connecting plate 2 constraint steel pipe and cross connecting plates; Form the hoop effect, reduce stress and concentrate, make each root steel pipe of node place stressed evenly; The bearing capacity and the rigidity of node have been improved, the weak member of the strong node that meets design requirement.Can change the angle of cut of steel pipe and junction plate according to the difference of architectural image.
