Revolving roof for an indoor/outdoor stadium
A moveable roofing system for covering an interior space includes a fixed half-dome roof fixed to and supported by a first support structure, a rotatable half-dome roof rotatable about and supported by a second support structure, the second support structure being concentric to the first support structure, and, wherein the rotatable half-dome roof is configured to rotate about the second support structure.
1. A revolving canopy roof for a spectator event, the roof comprising:
a semi-circular support ring;
an outer half-dome supported by the semi-circular support ring, the outer half-dome having a first diameter and a first leading edge, the first leading edge connected to a ground at a first position and at a second position, the first position opposed to the second position, and wherein the outer half-dome extends beyond the semi-circular support ring;
a circular support ring concentric with the semi-circular support ring; and
an inner half-dome having a second diameter less than the first diameter slideably connected to the circular support ring, the inner half-dome configured to revolve along the circular support ring.
2. The roof of claim 1 , wherein the first position is diametrically opposed to the second position.
3. The roof of claim 1 , wherein the outer half-dome tangentially extends beyond the semi-circular support ring.
4. The roof of claim 1 , wherein the semi-circular support ring is co-planar with the circular support ring.
5. The roof of claim 1 , wherein the inner half-dome is slideably connected to the circular support ring by roller bearings.
6. The roof of claim 1 , wherein the inner half-dome is positioned beneath the outer half-dome in an open position for creating natural ventilation.
7. The roof of claim 1 , wherein the first leading edge of the outer half-dome opposes a second leading edge of the inner half-dome in a closed position.
8. A stadium having a revolving roof, the stadium comprising:
a foundation;
a first plurality of support columns positioned in a semi-circular arrangement, the first plurality of support columns having a first end connected to the foundation;
a semi-circular support connected to a second end of the first plurality of support columns;
a fixed half-dome connected to the semi-circular support;
a second plurality of support columns positioned in a circular arrangement concentric with the first plurality of support columns, the second plurality of support columns having a first end connected to foundation;
a circular support connected to a second end of the second plurality of support columns, the circular support having a continuous channel circumferentially positioned within the circular support; and
a retractable half-dome having a plurality of rollers, the plurality of rollers supported within the continuous channel, wherein the plurality of rollers allows the retractable half-dome to revolve along the continuous channel.
9. The stadium of claim 8 , wherein:
the fixed half-dome has a first leading edge arch, the first leading edge arch connected to a ground at a first position and at a second position, the first position opposing the second position;
the retractable half-dome has a second leading edge arch; and
the first leading edge arch and the second leading edge arch are substantially coplanar when the revolving roof is in either an open position or a closed position.
10. The stadium of claim 9 , further comprising a tie cable connecting a first end of the second leading edge arch to a second end of the second leading edge arch, the tie cable further connected to the second leading edge arch by a plurality of cables extending from the retractable half-dome.
