The invention relates to truss structures containing belt trusses are interconnected by means of intermediate elements.

A known method of connecting belt truss element truss on which the belt trusses are connected with the corresponding connecting rod elements and/or with the appropriate belt core elements of the truss section. For the interconnection of elements are wedge connection (see RF Patent N 20039887 from 20.07.1995).

The disadvantage of this method is the complexity of the connection process, due to the complexity of the positioning rod elements relative to each other.

The technical result, which is aimed invention is to improve reliability and simplify installation of the relevant structures.

This technical result is achieved in that the connection of the belt truss element truss on which the belt trusses are connected with the corresponding connecting rod elements and/or with the appropriate belt truss elements truss sections, the ends of all the core elements perform with self-locking threaded, with each pair of connected e the cops threaded at their ends carry out in different directions, and their ends come in contact with each other due to the catching-up on the ends of the elements tightening couplings.

Core elements in one of the variants perform tubular and are connected by welding with threaded inserts.

The invention is illustrated by drawings.

In Fig.1 schematically shows a portion of a truss of Fig.2 - node connection of belt elements together.

Truss belt contains the elements 1, interconnected elements 2. Belt elements 1 made of pipes with welded at their ends threaded inserts 3.

When connecting belt elements 1 to each other at a threaded insert 3 with multidirectional Sanatornaya thread brings the coupling 4 to contact the ends of the threaded inserts 3. The coupling 4 are sections with opposite thread. The contact ends of the threaded inserts 3 further enhances the rigidity of the connection, and hence the rigidity of the metal. The combination of using Sanatornaya thread and contact the ends of the threaded inserts 3 significantly improves the reliability of connection, because it increases the probability that the connection is in working condition for the entire period of operation.
