A multifunctional extension for the Hockey & Tennis Club Ring Pass which also houses social services like day care.
The extension consists of a space frame supported by steel columns. This space frame is made of cardboard tubes and re-used Tuballs: steel balls used from recycled old projects. It is not the first time Octatube applied cardboard tubes. Octatube developed and produced as early as 2003 space frames and structures with cardboard tubes. But this is the first of a permanent nature.
Important for the structural integrity of the cardboard tubes is not to be damp. To prevent the tubes absorb moisture, the tubes are coated with a layer of polyethylene just below the outer winding. There is also placed a rubber seal between the flange plate and the cylinder.
In this project Octatube is testing different methods of surface protection.
- In the first row of squares a shrink sleeve is applied on de cardboard tubes.
- In the second row of squares a shrink sleeve is applied on the cardboard tubes including the flange plate.
- The cardboard tubes are protected by a layer of varnish in the third row of squares.
- Cardboard tubes without any treatment were applied in the fourth row of squares.
The choice of cardboard tubes is motivated by the desire to build sustainably. If the material would be applied more frequently, the construction is cheaper than a comparable steel structure.
It’s a big step towards a fully recyclable building or structure.
The facades are built up with insulating glass panels with a neutral suncoating and are strong enough to withstand flying hockey balls. The glass panels used in this project meet the contemporary requirements.
