The invention relates to the field of construction, namely the nodes connecting the tubular rods that are implemented in the manufacture of power transmission line supports, supports cellular etc.

Known collapsible connections, tubular rods, including the ends of the tubular rods with embedded gussets and attached flanges tightened between the bolts [RF Patent №2272109, IPC E04B 1/58. Bulletin No. 8 dated 20.03.2006].

A disadvantage of the known nodal connections of tubular rods that the site does not provide connection of several tubular rods: three, four, etc.

Know another hub connecting multiple tubular rods [Metal structures. The guide designer. Vol.2. Under the General editorship of V.V. Kuznetsov. M., 1998, str, Fig. 17,12 g].

Nodal connection of tubular rods includes the ends of the tubular rods with flanges which, when the screws are connected with similar flanges welded spatial insert, also of tubular elements.

The disadvantage of this connection node is the difficulty of manufacturing welding spatial insert flange.

Closest to the invention to the technical essence is the connection node of tubular rods, including top single tubular rod with a horizontal flange at stake is e and the return flange, to which angle attached intermediate segments of tubular elements with flanges at the ends, through which the flanges are attached to the lower tubular rods [the Patent for useful model №66363. IPC 02D 27/42. Bulletin No. 25 dated 10.09.2007].

The disadvantage of the connection node of the tubular rods is the increased consumption of steel and greater complexity of manufacturing due to the presence of the intermediate segments of the tubular elements and the spatial rigidity of the site as a whole.

The invention is aimed at reducing the consumption of steel, the complexity of the manufacturing process and increasing the stiffness of the node.

The technical result of the invention is ensured by the fact that the node connection of tubular rods, including top single tubular rod with a horizontal flange on the end of the second flange, to which the angle attached to the ends of the several lower tubular rods, and the flanges around the perimeter tightened bolts, second flange is made separately for each of the lower tubular rod, and the end of each tubular rod is further provided with two vertical flanges, which are tightened with bolts and similar flanges of adjacent ends of the tubular elements. The greatest efficiency is achieved if the tubular rods to perform in the form of a truncated pyramid multifaceted cross-Sich, the tion, in this case, all the ends of the tubular rods are connected to each node by the base of the pyramid.

Figure 2 shows a section 1-1 in figure 1. Figure 3 shows a section 2-2 in figure 1. Fig 3 shows a variant of the cross-section of the tubular rods.

The connection node of the tubular rods (site A, Figure 1) includes the upper single tubular rod 1, the end of which is attached a horizontal flange 2 and the counter flange 3, the flange 3, is made integral separately for each tubular rod, angle attached to the lower ends of the tubular rods 4, for example three. In addition, at the end of each tubular rod 4 are installed on the two vertical flange 5, which bolts 6 are tightened with similar flanges of adjacent ends of the tubular rods 4. The flanges 2 and 3 on the perimeter drawn between them by bolts 7. The basis of a single tubular rod 1 made, for example, in the form of a hollow truncated pyramid multifaceted cross-section (Figure 4), are welded to the horizontal flange 2. To the ends of the tubular rods 4 are welded response separate horizontal flanges 3 and additionally two vertical flange 5, mounted on the rods 4 with the possibility sommese the Oia them with similar flanges 5 of the adjacent tubular rods 4 to provide a spatial stiffness of the node. Combine the flanges 2, 3 and vertical flanges 5 with connecting with them and pull together respectively by bolts 6 and 7.
