Connect node.
Background technology
It is all that aluminum alloy materials have high-strength light, corrosion resistance good, processing characteristics, reflectivity high and color and luster is attractive in appearance etc.
Many advantages.Aluminium alloy can obtain the section bar in Various Complex section by extrusion forming technology, therefore be applied to more and more
Building structure field, is especially suitable for greenhouse of flora park, natatorium, rink and Petroleum Storage Tank etc. higher to requirement for anticorrosion
Building.Free form surface structure does not limit to the Analytical Expression with conventional curved-surface due to it, and curved form is more imbued with fluctuations, no
Visual impact is only had more, structure stress is also more reasonable.Therefore in the large span space knot that span is 50 meters to more than 100 meters
Structure field, the concern that free form surface structure is subject to is increasingly extensive.At present, applied in aluminium alloy single-layer latticed shell and studied most
Universal node is the gusset-type joint of Temcor companies of U.S. design.Such node passes through a large amount of bolts by the abdomen of I-shaped rod member
Plate is connected with upper and lower cover plates, and because web is discontinuous at its nodes domains, only top lower cover Transfer of Shear, shear behavior is poor, together
When bolt large usage quantity.Joint form is single to have become a big reason of limitation aluminum alloy latticed shell structure development, therefore needs
Research and development are adapted to the novel joint that aluminum alloy materials property, mode of transfer force are clearly reasonable, be easy to construction.Existing node uses H types
Rod member, causes resistance to overturning poor, while section of remaining silent has constructional difficulties again.
The content of the invention
The present invention uses H type rod members to solve existing node, causes resistance to overturning poor, while section of remaining silent is deposited again
In the problem of constructional difficulties, and then propose a kind of aluminium alloy assembled connecting node for large-span space structure.
The present invention is adopted the technical scheme that to solve above-mentioned technical problem：
A kind of aluminium alloy assembled connecting node for large-span space structure includes upper cover plate, lower cover, multiple certainly
Lock bolt and N number of box-type section workpiece, lower cover are arranged on the underface of upper cover plate, and N number of box-type section workpiece is with upper cover plate
Along the circumferential direction be uniformly arranged centered on axis, one end of each box-type section workpiece be inserted into upper cover plate and lower cover it
Between, it is affixed with upper cover plate and lower cover that box-type section workpiece passes through multiple self-locking screws.
The beneficial effect that includes compared with prior art of the present invention is：
1st, the present invention connects composition node structure, easy installation and removal, without Site Welding, construction speed by self-locking screw
Degree is fast, and operating efficiency can improve 30%~40%.
2nd, the present invention is using the box-type section rod member remained silent, and resistance to overturning is good, improves conventional node using H type workpiece
The shortcoming of less stable, enhances the tension resistance performance of node, so as to enhance the bulk strength of node.
3rd, the present invention fixes box section bar part using self-locking screw, solves the problems, such as section constructional difficulties of remaining silent.
