OJSC BRESTMASH has been producing metal structures for constructions for over 5 years. The works has been manufacturing nodal elements in the form of a hollow ball since 2005 (designed by V.I. Dragan, a professor of Brest Technical University). The following objects have been erected since with the use of such structures:
The BrGTU system nodal element is a hollow sphere with openings in which high-strength bolts with heads inside the sphere are inserted. This element is used for connecting rod elements (circular section tubes) thus forming a voluminous metal structure. The rod element transfers the longitudinal compressive force to the nodal element via a power nut and an external washer and the stretching force via the head of a high-strength bolt and the internal thread.
