Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
The present invention proposes a kind of containment type node, which includes the main chord for connecting pipe structure truss
With the bent plate of web member, the main chord part being connect with bent plate and web member part, main chord part and web member part are pipe structure purlin
Close to the bent plate in frame, belong to the part of the containment type node.Fig. 3 show the structure diagram of the containment type node,
In 1 be bent plate, 2 be main chord part, 3 be web part；Fig. 4 is the front view of bent plate in the containment type node；Fig. 4 a, figure
