Abstract
A roof structure and method of constructing the same wherein a large clear span is built over an existing or new athletic stadium or arena. The principal feature of the roof is that it is supported by Cable-Stays to towers standing outside the stadium and can be built over an existing stadium by cantilevering without entering the stadium, and places no added weight on the existing stadium. The structure includes a beam framework and a roof covering installed over the framework. The covering is fabricated of a clear skylight material to allow sufficient light transmission to permit a natural grass playing field, and it is openable to allow for ventilation.
Claims26
A methoid of contructing a roof over an existing stadium, said method comprising:
- (a) erecting a first row of cable stay towers outside one side of the stadium;
- (b) erecting a seocnd row of cable stay towers outside the side of the stadium opposite said one side;
- (c) cantileering roof structure in compression imparting relaionship from each row of said towers by progressively extending sections of said structure from said towers and over the stadium while suspending each sucessive section by a cable stay connection to the tower from which the section extends;
- and,
- (d) joining the roof structures cantilivered from the rows of towers in tension to partially relieve compressive forces of the structures on the towers and limit such forces.

A roof structure for use over an open topped stadium, said structure comprising:
- (a) a first row of cable stay towers located outside one side of the stadium;
- (b) a second row of cable stay towers located outside the stadium to the side thereof opposite said one side;
- (c) a first roof section cantilevered from the first row of towers anad extending therefrom partially over the stadium and toward the second row of towers, said section being disposed in compression imparting relationship to the first row of towers;
- (d) a second roof section cantilevered from the second row of towers and extending therefrom partially over the stadium and toward the first row of towers, said section being disposed in compression imparting relationship to the second row of towers;
- (e) first cable stay means extending from each row of said towers to suspend the load of the roof section cantilevered therefrom;
- (f) second cable stay means extending from each row of said towers to counterbalance the load imparted to the towers by the first cable stay means;
- and,
- (g) connecting means securing said roof sections together in tension to partially releive compressive forces imparted to the towers by said sections and limit such forces.

A method of constructing a roof over an existing stadium, said method comprising:
- (a) erecting a first row of cable stay towres outside one side of the stadium;
- (b) erecting a secodn row of cable stay towers outside the side of the stadium opposite said one side;
- (c) cantilevering roof structure from each row of said towers by progressively extending sections of said structure from said towers and over the stadium while suspending each successive section by a cable stay connection to the tower from which the section extends by the following steps:
- (i) preconstrcuting and disposing the roof sections at staging areas located at the foot of the towers;
- (ii) lifting the sections onto the towers by ground located cranes;
- (iii) initially suspendigg the sections in cantilevered relationship to the towers by tower located cranes;
- and,
- (iv) sucessively placing the sections in cantlivered relationship by traveling derrick cranes movable long the roof structure;
- (d) joining the roof structures cantilevered from the rows of towers to provide a cover over the stadium.
