Supply - Metal structure plate of the system "BrGTU" with hollow spheres units

Node node developed under patent RB 2489 dated 21.07.2005, made in the form of a hollow ball with holes in the wall (Photo 1) and is designed to connect the core element in the form of thin-walled tube profiles ogolovki which fitted tightly defined in their cavities special nuts . From the cavity of the ball skipped through the hole fastening bolts high strength steel XC 40 "Select" or 30HZMF with the power and locking nuts, with the possibility of special nuts vkruchivaniya hollow rod structure. Between the heads of bolts and the inner surface of the globe, as well as between the power nuts and the outer surface of the ball, set of spherical washers, addressed to the ball surfaces.

Offer description: 

An empty balloon is made of two hemispherical obtained by hot pressing of the sheets. In half the required diameter of the holes drilled under the bolts. The diameter of the holes assigned to 1 mm larger diameter bolt that provides free builds the structure of nodes. In the opening set on the hemisphere above with the power washer bolts and stop nuts. Hemispheres welded butt seam with the cutting edges of the connection type A17 according to GOST 5264-80 semiautomatic or automatic welding in the environment of carbon dioxide. When building the node power and a stop nut stop to one another by rotating the bolt with tightening nuts toward each other. Then, by rotating the brakes nuts with bolts, the latter vkruchivaetsya in a special hollow screw rod to lock power and lock nuts in a special nut, with the bolt head rests in the inner washer, and through it - in the wall of a hollow ball. At the conclusion of the power nut rotates in the opposite direction until the upiraniya the outer washer, and the stoporenie bolt on the ball by delaying power nuts. Similarly, the other node connected to the rods. Make holes in the wall of a hollow ball of a diameter greater than the diameter of bolts, provides an opportunity to rotate the bolts in the assembly site to the current angle, which simplifies the assembly site and the accuracy reduces manufacturing node. Structural design belong to the class of spatial core structures that are used most often as a load-bearing elements of building public and industrial supplies.

Technical and economic advantages of products: 

The opportunity of creating a big flight between the points of support, big (up to 500 kg/m2) load tolerance, easy manufacturing of the elements of the structure and their assembling, possibility of placing the engineering communications between the belts of structures. High reliability of the work of the unit, without the risk of the unit’s destruction along the welded seam, on the basic metal, including on the cross section of the apertures. The limiting condition of the hollow sphere comes as a result of the development of the so called plastic current of metal.
Economizing on steel consumption in comparison with the traditional designs. Reduction of costs of the wide-span constructions in comparison with the methods of using iron-concrete or wooden designs. The developed system "BrGTU" with the units of hollow spheres allows: - designing structural coverings for any loads; - lowering the demanded accuracy of manufacturing of the elements of a structure; - simplifying the assembly of the units essentially decreasing labor input.

Innovative aspects of the offer: 

The possibility of a large span between the supports, the perception of large loads of 500 kg/m2, the industrial manufacture of the structure and assembly, the possibility of engineering communications between the belts structures
