Node, cast aluminum node etc. mechanically connect node.In above-mentioned joint system, Temcor nodes are only applicable to H types section structural member company
Connect, other forms section can not be applied to, while nodes domains web is interrupted, and only relies on upper and lower cover plates transmission internal force；Aluminium alloy spiral shell
Bolt ball node is mainly for the connection of circular cross-section rod member, but its stiffness characteristics should not be used in single-layer lattice shell close to be hinged；Cast aluminium
Node is used to connect square-section rod member, has good out of plane stiffness, but cast aluminium ductility is poor, cost is high, constrains it
Engineer applied；Embedded node then deposits the problems such as planar rigidity is weaker.Meanwhile aluminium alloy structure has very very much not with steel construction
Together, do not use generally and be welded to connect.The operation inconvenience of one side welding scene, speed of application is slow, high to welder's level requirement；Second,
The welding of aluminium has specific requirement to welding material and welding procedure, and cost is higher；In addition, welding will drop to a certain extent
The material property of low aluminium alloy, aluminium intensity need to be according in its heat affected area《Aluminium alloy structure design specification》Relevant regulations enter
Row reduction.Therefore, development is still needed at present to possess good power transmission mechanism and reliability, processing and fabricating convenience, low cost, be easy to greatly
The novel aluminum alloy node of large-scale production processing.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided one kind is applied to aluminium alloy aperture and tied
The assembled space nodes of structure, the node can realize the prefabricated construction of aluminium alloy space structure, effectively prevent sweating heat
The weakening to aluminium alloy structure intensity is influenceed, the duration can be saved, reduce difficulty of construction, while the rigidity of node has been effectively ensured
And bearing capacity, it is beneficial to the popularization and application of aluminium alloy space structure.
The purpose of this utility model is achieved through the following technical solutions：
A kind of assembled space nodes applied to aluminium alloy aperture structure, for connecting the rod member for needing to assemble, including
Heavy wall aluminum pipe, shrouding and sleeve, the outer wall cutting of the heavy wall aluminum pipe are provided with joint face, and the joint face is provided with connection
Hole, the connecting hole are connected by high-strength bolt with the shrouding, and the shrouding is connected by connecting bolt with rod member, the set
Cylinder is arranged on the high-strength bolt between heavy wall aluminum pipe and shrouding, and the high-strength bolt is provided with chute, and the sleeve is provided with
The pin being engaged with the chute.
Each heavy wall aluminum pipe is provided with 4-8 joint face, and each joint face is provided with least two connecting holes.
The width of the joint face is more than the external diameter of sleeve.
The central axis of the connecting hole intersects with the central axis of heavy wall aluminum pipe.
Compared with prior art, beneficial effect caused by the technical solution of the utility model is：
When rod member is acted on by axial compressive force, axle power is transferred to heavy wall aluminum pipe by shrouding, sleeve；Rod member is acted on by axial tension
When, axle power is transferred to heavy wall aluminum pipe by shrouding, high-strength bolt；When node is by Moment, tensile region high-strength bolt and thickness
Wall aluminum pipe tension, compressive region sleeve and heavy wall aluminum pipe are pressurized.Ultimate bearing capacity of joints by high-strength bolt, sleeve and heavy wall aluminum pipe carrying
Power together decides on.Node using assembled design, include early stage processing factory assembly and the later stage engineering site peace
Dress, has good power transmission mechanism and reliability, can greatly shorten duration and repeatable dismounting, while can prevent welding pair
The adverse effect that node is brought.

Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 6, a kind of assembled space nodes applied to aluminium alloy aperture structure, needed for connecting
The rod member 4 of assembling, including heavy wall aluminum pipe 1, shrouding 3 and sleeve 6, the outer wall cutting of heavy wall aluminum pipe 1 are provided with joint face, this implementation
Heavy wall aluminum pipe 1 in example is provided with six joint faces, and each joint face is provided with two connecting holes 2, and connecting hole 2 passes through high-strength spiral shell
Bolt 5 is connected with shrouding 3, and shrouding 3 is connected by connecting bolt 8 with rod member 4, and sleeve 6 is arranged between heavy wall aluminum pipe 1 and shrouding 3
High-strength bolt 5 on, high-strength bolt 5 is provided with chute 9, and sleeve 6 is provided with the pin 7 being engaged with chute 9.
Further, heavy wall aluminum pipe 1 chooses thick-wall aluminum alloy pipe and uses flat cutting, milling, drilling, tapping etc. in the present embodiment
Technique makes, and milling flat should be vertical with connecting hole on the outside of heavy wall aluminum pipe, and width is not less than the external diameter of sleeve 6；The depth of connecting hole 2
No less than 1.3 times of high-strength bolt nominal diameters, the central axis of connecting hole intersect with the central axis of heavy wall aluminum pipe, the angle of cut by
The angle of cut of rod member and heavy wall aluminum pipe central axis determines that two connecting holes for connecting same rod member are parallel to each other, in heavy wall aluminum pipe 1
Ring rib and rice word rib can be set to increase connection stiffness and bearing capacity in portion, avoids aluminum joints from being produced under load action
