KK-BALL NODE SYSTEM
- Load applied to the nodes
- Single or Multi-layer
- Each node has up to 18 threaded holes as pin jointed connections
- Gives greatest freedom in design
The MERO KK-System, the 1st prefabricated Spaceframe System, has a high degree of versatility in its applications. Spaceframes are filigree systems out of nodes and members. Loads are applied via the nodes, the members distributes the compression and stress forces.
The members are round hollow sections because they have the best resistance against buckling. Diameters range from 30 to 355mm with different wall thickness. The length differs from 1.5m to 5.0m but is not fixed. The nodes are balls, to give a free selection for the connection holes. The standard ball nodes have diameters from 49.5mm to 350mm. To connect several members to a relatively small node, the members will have to be conical at the ends. The members are connected via high tensile bolts. The bolt has a dowel pin and is screwed into the node via a sleeve. Compression is transmitted via the sleeve, stresses via the bolt. Single and multi-layer Spaceframes can be designed.
Loads from cladding or suspended loads should be applied via the nodes. Membranes are directly fixed to the nodes while roofing sheets are fixed to the purlins which are attached to the nodes via a purlin stool.
This System can be of steel, aluminium or stainless steel.
The KK-System can be combined within on project with NK-System, BK-System or even traditional steel sections.
