## CPC

- E04B 7/028: {consisting of structures of pyramidal or conical shape}
- E04B: GENERAL BUILDING CONSTRUCTIONS; WALLS, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; INSULATION OR OTHER PROTECTION OF BUILDINGS (border constructions of opening in walls, floors or ceilings E06B1/00; {electromagnetic shielding H05K9/0001})

## Abstract

A new conical roof building method provides flat plates having straight abutting edges and curved outer edges. The plates are placed horizontally edge to edge except for a sectoral opening. The plates are welded together to form a flat disc-shaped blank, leaving an open sector of the blank. Radial supports are welded to a top of the disc-shaped blank. A center of the disc-shaped blank is lifted, forming a conical-shaped structure, closing and abutting edges of the open sector and touching edges of the formerly open sector are welded together, completing the forming of the conical roof.

## Claims

### Claim 1

A conical roof building method, comprising providing plates having straight abutting edges and curved outer edges, welding the plates together and forming a disc-shaped blank and leaving an open sector of the blank, welding radial supports to a top of the disc-shaped blank, lifting a center of the disc-shaped blank and forming a conical-shaped structure, abutting edges of the open sector and securing edges of the open sector together, and completing the forming of the conical roof further comprising initially supporting the plates on a table structure and supporting curved edge portions of the plates on upper edges of a cylindrical shell ring before and during the welding of the plates together and the welding of the radial supports to the top of the disc-shaped blank.

### Claim 2 (depends on 1)

The method of claim 1, further comprising supporting the blank and the conical-shaped structure on lower edges of the shell ring during the lifting of the center of the disc-shaped blank and the forming of the conical-shaped structure, and the securing of abutting edges of the open sector.

### Claim 3 (depends on 2)

The method of claim 2, further comprising supporting the completed conical roof on the upper edges of the shell ring.

### Claim 4 (depends on 3)

The method of claim 3, further comprising welding the conical roof to the outer edges of the shell ring.

### Claim 5 (depends on 1)

The method of claim 1, wherein the securing edges of the open sector comprises welding the abutting edges of the sector together.

### Claim 6 (depends on 5)

The method of claim 5, wherein the securing edges further comprises welding bridging strips across the abutting edges of the sector.

### Claim 7

A conical roof building method, comprising providing plates having straight abutting edges and curved outer edges, welding the plates together and forming a disc-shaped blank and leaving an open sector of the blank, welding radial supports to a top of the disc-shaped blank, lifting a center of the disc-shaped blank and forming a conical-shaped structure, abutting edges of the open sector and securing edges of the open sector together, and completing the forming of the conical root further comprising welding a compression ring to upper and inward portions of the radial supports after completing the forming of the conical roof.

### Claim 8

A conical roof building method, comprising providing plates having straight abutting edges and curved outer edges, welding the plates together and forming a disc-shaped blank and leaving an open sector of the blank, welding radial supports to a top of the disc-shaped blank, lifting a center of the disc-shaped blank and forming a conical-shaped structure, abutting edges of the open sector and securing edges of the open sector together, and completing the forming of the conical roof further, comprising supporting the plates on plural parallel tables and supporting outer curved edge portions of the plates on a circular upper edge of a shell ring before and during the welding of the plates together and the welding of the radial supports to the top of the disc-shaped blank.

### Claim 9 (depends on 8)

The method of claim 8, wherein the welding of the radial supports to the top of the disc-shaped blank comprises welding lower edges of angle iron vertical flanges at intervals to the top of the disc-shaped blanks, and wherein the completing of the forming of the conical roof further comprises welding the entire edges of the vertical flanges of the angle iron radial supports to conical surfaces of the conical roof.

### Claim 10 (depends on 9)

The method of claim 9, further comprising providing an opening in a center of the blank and extending alternating supports from the center opening to the outer curved edge of the blank and extending alternate intermediate support from the outer edge of the blank to positions spaced from the central opening.

### Claim 11 (depends on 10)

The method of claim 10, wherein the lifting of the center of the blank with an element connected to a lifting ring, and lifting the center of the blank with a crane attached to the lifting ring.

### Claim 12 (depends on 10)

The method of claim 10, further comprising lifting the center of the blank with a vertical rain positioned under the center of the blank.
