Composite elevated tank and method of construction

A method of building a composite elevated storage tank comprising steps of:

• building a reinforced concrete pedestal on a foundation at a storage tank site;
• coupling a tank anchor assembly with a top of said reinforced concrete pedestal, wherein said tank anchor assembly comprises anchor plates with anchor bolts through a side of said reinforced concrete;
• preparing a temporary tank support;
• building a steel tank on said temporary tank support, said steel tank having a first cone section, one or more levels of tank shell side wall, a roof, and a base plate;
• lifting said steel tank onto said reinforced concrete pedestal such that said base plate is positioned adjacent said tank anchor assembly;
• and
• coupling said base plate to said tank anchor assembly.

A method of building a composite elevated storage tank comprising steps of:

• building a reinforced concrete pedestal on a foundation at a storage tank site;
• coupling a tank anchor assembly with a top of said reinforced concrete pedestal, wherein said tank anchor assembly comprises an anchor chair supporting an anchor bolt disposed laterally from said reinforced concrete;
• preparing a temporary tank support;
• building a steel tank on said temporary tank support, said steel tank having a first cone section, one or more levels of tank shell side wall, a roof, and a base plate;
• lifting said steel tank onto said reinforced concrete pedestal such that said base plate is positioned adjacent said tank anchor assembly;
• and
• coupling said base plate to said tank anchor assembly.

A method of building a composite elevated storage tank comprising steps of:

• building a reinforced concrete pedestal on a foundation at a storage tank site;
• coupling a tank anchor assembly with a top of said reinforced concrete pedestal, wherein said tank anchor assembly spans the full width of the concrete in the reinforced concrete pedestal;
• preparing a temporary tank support;
• building a steel tank on said temporary tank support, said steel tank having a first cone section, one or more levels of tank shell side wall, a roof, and a base plate;
• lifting said steel tank onto said reinforced concrete pedestal such that said base plate is positioned adjacent said tank anchor assembly;
• and
• coupling said base plate to said tank anchor assembly.

A method of building a composite elevated storage tank comprising steps of:

• building a reinforced concrete pedestal on a foundation at a storage tank site by beginning with a first section of formwork for said reinforced concrete pedestal and placing steel reinforcement and wet concrete inside the formwork and then repeating to achieve, with additional sections or lifts, an increasing height for said reinforced concrete pedestal until a penultimate level has been achieved;
• preparing a temporary tank support;
• building a steel tank on said temporary tank support by fabricating an assembly comprising a first cone section, a skirt welded to a bottom of said first cone section, and a base plate welded to a bottom of said skirt;
• placing said assembly on said temporary tank support by setting said base plate on said temporary tank support;
• continuing to build said steel tank from the bottom upwards by welding additional cone sections above said first cone section until a desired number of additional cone sections has been achieved;
• welding plates of a first level of tank shell to a top level of an uppermost cone section of said additional cone sections;
• continuing to add levels to said tank shell by welding plates of additional levels to each successive lower level until a desired height of said tank shell has been achieved;
• in an ultimate lift of the reinforced concrete pedestal, placing a tank anchor assembly at the top of the formwork;
• lifting said steel tank onto said reinforced concrete pedestal such that said base plate is positioned adjacent said tank anchor assembly;
• and
• coupling said base plate to said tank anchor assembly.

A method of building a composite elevated storage tank comprising the steps of:

• building a foundation at a storage tank site;
• building a temporary tank support near said foundation and at said storage tank site;
• building a reinforced concrete pedestal on said foundation;
• fastening a tank anchor assembly onto said reinforced concrete pedestal;
• building a steel tank on said temporary tank support, said steel tank having a first cone section, one or more levels of tank shell side wall, and a roof, wherein said first cone section further comprises a skirt depending therefrom, and said skirt further comprises a base plate welded to a bottom of said skirt;
• lifting said steel tank onto said reinforced concrete pedestal such that said base plate sits on said tank anchor assembly;
• and
• welding said base plate to said tank anchor assembly.
