Background technology
It is all that aluminum alloy materials have that high-strength light, corrosion resistance be good, processing characteristics, reflectivity are 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, apply and study most in aluminium alloy single-layer latticed shell
Universal node is the gusset-type joint of Temcor companies of U.S. design.Such node is by 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.
Utility model content
The utility model causes resistance to overturning poor, while section of remaining silent to solve existing node using H type rod members
The problem of there are constructional difficulties again, and then propose a kind of aluminium alloy assembled connecting node for large-span space structure.
The utility model adopts the technical scheme that to solve above-mentioned technical problem：
A kind of aluminium alloy assembled connecting node for large-span space structure include upper cover plate, lower cover, it is multiple from
Bolt and N number of box-type section workpiece are locked, lower cover is 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, box-type section workpiece is affixed by multiple self-locking screws and upper cover plate and lower cover.
The beneficial effect that the utility model is included compared with prior art is：
1st, the utility model is by self-locking screw connection composition node structure, and easy installation and removal, without Site Welding, is applied
Work speed is fast, and operating efficiency can improve 30%~40%.
2nd, the utility model is using the box-type section rod member remained silent, and resistance to overturning is good, improves conventional node using H types
The poor shortcoming of workpiece stability, enhances the tension resistance performance of node, so as to enhance the bulk strength of node.
3rd, the utility model fixes box section bar part using self-locking screw, solves asking for section constructional difficulties of remaining silent
Topic.
