With flourishing for China's steel building, the application of steel truss is more and more extensive, and steel truss has transparent surface
Product is big, the advantages that occupying little space, can meet the needs of high-grade hotel and shopping center are for space, span and daylighting.Steel
Truss is made up of rod member more, and rod member is mostly straight line rectangular steel pipe, because steel truss often integrally has certain radian, its radian
Realized, i.e., realized by way of node transition is broken line by broken line.
The multidirectional handing-over box node of node generally use of steel truss, and multidirectional handing-over box node generally has intersection
And connecting portion, because multidirectional handing-over box node closure is multidirectional, each closure all has a connecting portion, respectively
Line between individual adjacent connecting portion angle summit forms center bending line, and the part within the bending line of center is multidirectional handing-over
The intersection of box node（Each adjacent connecting portion angle summit is each summit of intersection）, multiple connecting portions are with crossing
Portion fixes and forms a node entirety.Multidirectional handing-over box node often joins box node and six to cross-connecting box with four-way at present
Two kinds of type node, multidirectional handing-over box node are divided into main tank and time case, are space bending structure, its structure is lower folding from the bottom to top
Curved whole plate → web（Main tank web and time case web）, stiffened panel, shrouding → upper bending whole plate.As shown in Figure 1 six are to handing-over
Box node（With six connecting portions）Join box node with the four-way shown in Fig. 2（With four connecting portions）, under including
Bending whole plate 31, upper bending whole plate 32, main tank web 33, secondary case web 34, main tank shrouding 35, secondary case shrouding 36 and stiffened panel
37；Wherein main tank web 33, secondary case web 34 and stiffened panel 37 are highly equal, main tank web 33, secondary case web 34 and stiffened panel
37 are arranged between lower bending whole plate 31 and upper bending whole plate 32 and play a supportive role, and main tank web 33 is two pieces parallel and logical
Long whole plate, secondary case web 34 are fixed on the both sides of main tank web 33, and stiffened panel 37 is fixed between two main tank webs 33, main tank
Shrouding 35 closes the termination of the multidirectional handing-over each connecting portion of box node with time case shrouding 36.Multidirectional handing-over box node at present
Upper and lower bending whole plate carry out whole plate blanking, professional bending machines radian, it is ensured that truss structure seamlessly transits.But by
Belonging to space bending structure in the rod member connected with node, section is small, on precision is made, angle, length to node joint
And plain bending radian proposes higher requirement, the box welding node of construction handing-over at present also has many difficulties, such as makes
Precision is low, complex procedures, low construction efficiency, and workmen is not easy to grasp.
