The invention relates to the construction, in particular, to the core spatial structure. Hub connection can be used as a flat spatial structures and two lap shells made of metal or wood. Examples of such structures are the structures, cylindrical shell, dome, etc.

Known nodal connection rod to the spatial structure used for connecting tubular elements (Kudishin SCI and other Metal structures, 8th ed., revised and enlarged extra - M.: Publishing center "Academy" 2006, str, RES,6) [1].

The disadvantage of [1] is the complexity of manufacturing, especially in cases of its use in the core spatial structures made from profiles netrebkothe section.

The closest analogue to the claimed invention is a hub connecting rod spatial design, including disks, pulled together by a pin passed through the Central openings of the disks, between which is placed the tips of the lap and diagonal rods (Troshev A.G. dimensional metal structures. - M, stroiizdat, 1983, str, rich) [2].

A disadvantage of the known solution [2] is the complexity of manufacturing, as well as lack of reliability associated with increased stiffness of the node and with a large number of welds in the connection.

The technical result of the invention is to reduce the complexity of manufacturing and reliability of nodal connections.

This technical result is achieved due to the fact that the host connection rod spatial design, including disks, pulled together by a pin passed through the Central openings of the disks, between which is placed the tips of the lap and diagonal rods, provided with a connecting ring disposed between the disks, casilino with them, passed through him hairpin, with each tip of the lap bar is in the form of a hook, the horn of which is directed towards one of the drives and has an axis located perpendicular to the axis of the lap rod, and each tip of the diagonal rod is made in the form of a hook, the horn of which is directed toward the other disk and has an axis that is located obliquely to the axis of the diagonal rod, with horns all hooks placed in the hole of the connecting ring around the pin.

Tips can be made in the form of plates.

The front part of each horn can be made triangular with a middle and two side faces, the average face is in contact with the stud.

The side faces can be connected flush with the side edges of adjacent horns.

Edges can be connected by the geometry of the mini-circuit with the side edges of adjacent horns through the strip.

The side faces can be connected flush with the side edges of adjacent horns by means of glue or crimp.

The side faces can be made parallel to the axis of the stud.

The longitudinal axis of the lap and diagonal rods can be centered at a point on the plane of symmetry of the binder rings.

The connecting ring and the disks can be made in the form of plates and in contact with it the surface of the tips made flat.
