A TENT STRUCTURE FOR A MOBILE THEATRE

WORKING DETAILS - HORSE + BAMBOO THEATRE

The pPOD mobile theatre has a floor frame of 100 x 100mm rectangular hollow aluminium sections fitted together and set to correct positions with bracing cables. Plywood floor panels fit onto the frame. Six twisted rectangular frames of 40mm-diameter aluminium tubes form the structure. They are connected at node points by solid steel bars. Because each node point connection is at several different angles, a colour-coded labelling system was developed to ensure fast erection. To reduce complexity in welding and cutting, a solid steel ball was used at the centre of each node and tubes were simply cut at right angles.

At its base each tube has a 35mm-diameter stainless steel pin riveted to it which slots into a 42mm-diameter steel sleeve welded to the top lip of the aluminium floor frame. The inner frames of 40mm-diameter curved aluminium tubes are fixed in a similar manner.

The outer fabric is pulled over the rectangular frames; cleats, running on the inside of the fabric at the base, are secured to an 40mm-diameter stainless steel tube fixed by steel cleats welded to the floor frame.

The inner fabric is clipped with cleats to the curved inner frame.

The pPOD is a light structure. When used outdoors it has to be anchored to the ground by ground anchors or counterweights connected to the perimeter of the aluminium floor frames.
