Abstract
The utility model discloses a compound node in large suspended-raise space structure, which is composed of a square pipe and a round pipe. A node ball is fixed and inlaid in the square pipe, at least one ear board extends out from the node ball, and the end of the round pipe is fixed with a joint which is connected with the ear board on the node ball. The utility model not only solves the problem of connecting the square pipe and the round pipe, ensures the connection intensity, but also has the advantage of good shape.
Description
Technical field
The utility model relates to a kind of steel structure node, especially for a kind of connected node in the big cantilever space structure.
Background technology
Big cantilever space structure is a branch of large-span space structure, and mainly the agent structure as top cover is used in the utilities building of coliseum and specific type.Node is the core of steel work, and the big increasingly sophisticated application various and hybrid structure of cantilever space construction profile causes joint form also to be tending towards variation and complicated.Tubular joint, cast steel node and some mixed nodes etc. of the direct junction of tube and tube on the basis of initial plate node and ball node, have been developed again.Pipe and pipe intersection common practices are tubular joint or ball node, the existing application in the domestic Other Engineering.For the consideration of aspect such as attractive in appearance, square tube has begun to be applied on structure design in the big cantilever space structure, does not still have ripe standard and technology can be used for reference and the type of attachment of square tube and pipe and square tube and many pipes is domestic.The form of at present existing node has not caught up with the needs of architectural design, is badly in need of developing novel node structure form.
The utility model content
The technical problems to be solved in the utility model provides and is used for square tube and the mutual cross-coupled a kind of composite node of pipe in a kind of big cantilever space structure.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the composite node in a kind of big cantilever space structure, comprise square tube and pipe, also have a bolted node sphere fixedly to be embedded in the square tube, protruding at least one otic placode on the bolted node sphere, a connector is fixed in the end of described pipe, and this connector is fixedlyed connected with the otic placode on the bolted node sphere.
The utility model is provided with connector in the end of pipe, on square tube, be provided with bolted node sphere, can stretch out a plurality of otic placodes on the bolted node sphere is connected with connector on the pipe, not only solved the difficult problem that square tube is connected with pipe, guarantee the requirement of strength that connects simultaneously, and had advantage handsome in appearance.
A kind of preferred version as technique scheme, tailgate and two clamping plates that described connector is fixed on the shrouding of the pipe mouth of pipe by one and is fixed on the shrouding both sides constitute, wherein tailgate inserts in the pipe and with pipe and fixedlys connected, two clamping plates is parallel to each other, and the otic placode on the bolted node sphere inserts between the two clamping plates and with bolt and connects.This connected mode is simple in structure, easy construction.
A kind of preferred structure of above-mentioned bolted node sphere is the hollow ball that is spliced by at least two spheres, and described otic placode runs through sphere and fixedlys connected with sphere along centre of sphere direction.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of composite node of the utility model.
Fig. 2 is the schematic diagram of pipe end coupling.
Fig. 3 is a kind of STRUCTURE DECOMPOSITION schematic diagram of hollow bolted node sphere.
The specific embodiment
As shown in the figure, bolted node sphere 2 is embedded in the square tube 1, and is connected with the mode and the square tube 1 of welding, and bolted node sphere 2 is the hollow balls that are spliced by four spheres, and otic placode 3 runs through sphere and is welded as a whole with sphere along centre of sphere direction.A connector 4 is fixed in the end of pipe 5, this connector 4 is made of at the shrouding 42 of pipe 5 mouths of pipe and the tailgate 43 and the two clamping plates 41 that are fixed on shrouding 42 both sides a block welding, wherein tailgate 43 inserts in the pipe 5 and with pipe 5 and fixes welding, two clamping plates 41 is parallel to each other, otic placode 3 on the bolted node sphere 2 inserts between the two clamping plates 41, and connects otic placode 3 and two clamping plates 41 with bolt.So just can realize being connected of square tube and many pipes.
