Tree forked members is mainly applicable to moulding class building and large-span truss structure.When conventional trussed construction adds large span as need, need increase truss cross section, rod member specification, cost also can significantly rise; Tree forked members is modern design, nature attractive in appearance not only, and more economical reasonable.Tree forked members is mainly applicable to steel column and the view post of truss frame for connecting.
Have the following advantages:
1, rationally increase building interior usage space, reduce post position, add large span, with minimum economic cost, obtain maximum utilized space.
2, modern design is unique, and to set fork attitude, natural atmosphere, has higher ornamental value, and makes building full of vitality, becomes the masterpiece of taking the course of its own in Green environmental-protection building field.
3, simple and reasonable, easy to process quick, than traditional longspan structure, reduce steel using amount 30%, effectively controlled cost.
4, node is by mold pressing heat forming technology, and adopts special-purpose fine finishining facility, has higher precision, and can enhance productivity 30 ~ 35% than traditional craft or semi-automatic cutting.
5, adopt reasonably " node assembling method ", greatly reduced member assembly positioning difficulty, and reduced installation cost, guaranteed weldquality and rod member positioning precision, and can improve installation effectiveness 20 ~ 25%.
In a word, can be fast, accurately, facilitated the blanking, shaping, the welding equipment that are applicable to set forked members, and very economical, raw material and processing cost only account for 60% of traditional longspan structure.
Therefore, a kind of tree forked members of the present invention and processing method thereof, compact conformation, modern design, rational in infrastructure, stressed reliable, economize on resources, processing fast accurate.
