System and method of forming at least a portion of a reinforced roof structure from sandwich panels

Abstract

A roofing system includes a first sandwich panel, a second sandwich panel and a support panel. The first sandwich panel, which forms at least a portion of the roof structure, has a first outer layer and a second outer layer spaced from the first outer layer by a panel core. The first sandwich panel includes a first angle edge, which includes an edge portion of the panel core and an edge portion of at least the first outer layer. The second sandwich panel includes a first outer layer and a second outer layer spaced from the first outer layer by a second panel core, wherein the edge portion of the first sandwich panel is supported, at least in part, by one or more outer surface Depending on the length of the roofing system and / or other design criteria, the roofing system includes one or more support panels secured between the first sandwich panel and the second sandwich panel to provide additional support for the roof structure.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates generally to constructing buildings, and more particularly, to a roofing system for reinforcing and / or stiffening at least a portion of a roof structure formed from one or more composite sandwich panels.DESCRIPTION OF THE RELATED ART[0002]There is an increasing global demand for lower-cost buildings such as houses, warehouses and office space. The demand for lower cost buildings is particularly strong in developing countries where economic resources may be limited and natural resources and raw materials may be scarce. For example, in areas of the Middle East or Africa, conventional building materials such as cement, brick, wood or steel may not be readily available or, if available, may be very expensive. In other areas of the world, poverty may make it too costly for people to build houses or other buildings with conventional materials.[0003]The demand for lower-cost housing also is high in areas afflicted by war o...

AI Technical Summary

Benefits of technology

[0005]The present invention provides an alternative to conventional construction materials and techniques. Buildings, such as houses, commercial buildings, warehouses, or other structures can be constructed by composite sandwich panels (also referred to as “sandwich panels” or “composite panels” or “panels”), which have an insulative core and one or more outer layers. The buildings can be constructed by gluing several sandwich panels together, and usually traditional fasteners, such as screws, rivets, nails, etc., are not needed for such connections. Generally, composite sandwich panels offer a greater strength-to-weight ratio than traditional materials that are used by the building industry. The composite sandwich panels are generally as strong as, or stronger than, traditional materials including wood-based and steel-based structural insulation panels, while being lighter in weight. Because they weigh less than traditional building materials, the handling and transport of composite sandwich panels is generally less expensive. The composite sandwich panels also can be used to produce light-weight structures, such as floating houses, mobile homes, or travel trailers, etc.

[0006]Sandwich panels generally are more elastic or flexible than conventional materials such as concrete, steel or brick and, therefore, monolithic buildings made from sandwich panels are more durable than buildings made from conventional materials. For example, sandwich panels also may be non-flammable, waterproof and very strong and durable, and in some cases able to resist hurricane-force winds (up to 300 Kph (kilometers per hour)). The panels also may be resistant to the detrimental effects of algae, fungicides, water, and osmosis. As a result, buildings constructed from sandwich panels are better able to withstanding earthquakes, floods, tornados, hurricanes, fires and other natural disasters than buildings constructed from conventional materials.

[0007]Sandwich panel structures may be less expensive to build than structures built from conventional materials because of reduced material costs and alternative construction techniques. The ownership and maintenance costs for sandwich panel structures also may be less over the long term because sandwich panel structures may last longer and degrade at a slower rate than buildings made from conventional materials. Structures built from sandwich panels therefore may require less maintenance and upkeep than structures built from conventional building materials, which may reduce the overall ownership costs for end users.

[0008]The insulative core of the sandwich panels also may reduce the amount of energy needed to heat and / or cool the building, which may reduce the overall costs to operate the building. The insulative core also may reduce or eliminate the need for additional insulation in the building, as may be necessary to insulate structures built from conventional building materials. Sandwich panel structures therefore may be less expensive to build and operate than buildings constructed from conventional building materials.

Problems solved by technology

The demand for lower cost buildings is particularly strong in developing countries where economic resources may be limited and natural resources and raw materials may be scarce.

For example, in areas of the Middle East or Africa, conventional building materials such as cement, brick, wood or steel may not be readily available or, if available, may be very expensive.

In other areas of the world, poverty may make it too costly for people to build houses or other buildings with conventional materials.

These devastating events often lead to widespread destruction of large numbers of buildings and houses, especially when they occur in densely populated regions.

The rebuilding of areas affected by these events can cause substantial strain on the supply chain for raw materials, making them difficult or even impossible to obtain.

Furthermore, natural disasters often recur and affect the same areas.

If a destroyed building is rebuilt using the same conventional materials, it stands to reason that the building may be destroyed or damaged again during a similar event.

Prefabricated buildings, however, are made from conventional materials and may be scarce or expensive to obtain.

Structures built from sandwich panels therefore may require less maintenance and upkeep than structures built from conventional building materials, which may reduce the overall ownership costs for end users.
