Abstract
An insulated roof includes a deck which acts as a diaphragm and a plurality of interlocked roof panels which carry vertical loads. A layer of insulation is also included, as are bearing plates.
Claims14
A building roof comprising:
- a corrugated roof deck securely mounted on structural elements of a building;
- a layer of rigid insulation on said roof deck layer;
- a plurality of roof panels on said insulation and joined together by a joint which does not penetrate said roof panels;
- a clip unit which includes a body, a bottom plate and a hook means joined to said roof panel joint, said hook means being movably connected to said body so that said joined roof panels are movably connected to said clip unit;
- a bearing plate located between said clip unit bottom and the top of said insulation, said bearing plate having a surface area greater than the surface area of said clip unit bottom plate to distribute any force generated by said clip unit on said insulation over an area which is large compared to said clip unit bottom plate to protect said insulation from damage thereto caused by said clip unit;
- fastening means securely connecting said clip unit, said bearing plate, said insulation and said roof deck to a building structural element so that said joined roof panels are movably mounted on the building structural element, said bearing plate permitting secure fastening of said clip units, said insulation and said roof deck to said structural elements without endangering said insulation;
- said roof deck accommodating horizontally directed loading on a building and said movably mounted roof panels accommodating expansion and/or contraction of said joined rood panels, by reason of said insulation being securely positioned on top of said roof deck said roof deck horizontal load accommodating capability is increased by said insulation and roof panels over such capability of a roof deck alone.

A method of erecting a roof comprising steps of:
- pre-punching holes in building structural elements;
- placing a corrugated deck on the building structural elements;
- gauging the deck to identify the locations of the pre-punched holes in the building structural elements;
- punching holes in the deck to correspond to the pre-punched holes;
- placing a layer of rigid insulation on the deck;
- gauging the layer of insulation to identify the locations of the pre-punched holes in the building structural elements;
- punching holes in the insulation to correspond to the pre-punched holes;
- placing a bearing plate on top of the insulation;
- assemblying a clip unit to include a body, a bottom plate and a hook which is to be joined to roof panels and movably connecting the hook to the body so that a roof panel connected to the body by the hook is movable with respect to the body;
- placing the clip unit on top of the bearing plate;
- attaching the bearing plate, clip unit, insulation and deck to a building structural element;
- tightening the clip and bearing plate securely against the insulation so the insulation is securely tightened against the roof deck so that the diaphragm capability of the roof deck and insulation is increased;
- placing roof panels on the insulation;
- and
- interlocking the roof panels with the clip unit.

- a layer of rigid insulation on said roof deck layer;
- a plurality of roof panels on said insulation and joined together by a joint which does not penetrate said roof panels;
- a clip unit which includes a body, a bottom plate and a hook means joined to said roof panel joint, said hook means being movably connected to said body so that said joined roof panels are movably connected to said clip unit;
- a bearing plate located between said clip unit bottom and the top of said insulation;
- fastening means securely connecting said clip unit, said bearing plate, said insulation and said roof deck to a building structural element so that said joined roof panels are movably mounted on the building structural element, said bearing plate permitting secure fastening of said clip units, said insulation and said roof deck to said structural elements without endangering said insulation;
- said roof deck accommodating horizontally directed loading on a building and said movably mounted roof panels accommodating expansion and/or contraction of said joined roof panels, by reason of said insulation being securely positioned on top of said roof deck said roof deck horizontal load accommodating capability is increased by said insulation and roof panels over such capability of a roof deck alone.
