Self aligning three dimensional support structure for a roof constructed with prefabricated components

Abstract

The invention provides a method for easy prefabrication of a self aligning three dimensional roof support and roof structure, such as a dormer or porch roof, which is fully constructed of sheet goods with tab and slot interconnecting components. The roof support structure is constructed of a parallel aligned space series of substantially rigid sheet truss members and a parallel aligned space series of substantially rigid purlin members running perpendicular to the truss members and interlocked with the truss members with opposing interlocking slots to form a self- aligning three dimensional support structure whereby the flush upper sheet ends provide support for roof sheathing. The roof sheathing and additional side fascia members are fit to the substructure with inter-engaging tabs and slots.

Description

BACKGROUND OF THE INVENTION[0001]The present invention pertains to support structures, and more particularly to a self aligning three dimensional support structure for a roof, such as a dormer or a porch roof, which is constructed of prefabricated components.BACKGROUND OF THE INVENTION[0002]The conventional construction problem encountered for detailed porch roofs and dormers is that they are labor intensive, especially if they include curves. Conventional stick frame construction also involves expensive lumber, heavy weight, waste of materials, and expansion and contraction issues.[0003]It is a principal object of the present invention to construct tradition style porch roofs and dormers with high efficiency.SUMMARY OF THE INVENTION[0004]The three dimensional support structure for a roof of the present invention is constructed of prefabricated components, which, when assembled, are self aligning to efficiently provide a dormer or a porch roof The support structure of the present in...

Benefits of technology

[0007]The unique roof support structure of the present invention provides the convenient opportunity for manufacturing all of the sheet good structure members and roof sheathing to be cut to appropriate size, shape and dimension with a preprogrammed CNC router machine. The machine is programmed whereby a minimum of only projection, width, and height to ridge dimensions are required to be input into the CNC router in order to provide production of all the prefabricated parts or components, with slots and tabs as required, for shipping and assembly of the support structure.

[0008]The prefabricated component roof support structure of the present invention provides many advantages over conventional stick frame construction. The system of the present invention provides extreme labor savings, affordable shipping and packaging in component form, low skill level for assembly, and limitation in variation of the types of materials required to construct the structure since it is produced primarily from sheet goods, which in addition, permits the utilization of CNC machinery for fabrication.

[0009]The ultimate construction is also stronger than conventional framing, light weight and the tab and slot construction provides self-alignment of the structure. The use of a tape measurer is not even required to frame the unit.

Problems solved by technology

The conventional construction problem encountered for detailed porch roofs and dormers is that they are labor intensive, especially if they include curves.

Conventional stick frame construction also involves expensive lumber, heavy weight, waste of materials, and expansion and contraction issues.
