ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to modular building panels utilized to fabricate the walls, ceilings, floors, etc. of cabanas, porches, and the like.
BACKGROUND OF THE INVENTION
The use of modular building panels is popular a popular method for economically adding additional enclosed structures to a pre-existing structure. Examples of new structures include room additions, cabanas, and enclosed porches. In many cases these room additional enclosures are used for leisure activities such as reading, watching television, and visiting with guests.
Typically modular building panels cost less than conventional construction materials. Modular building panels may be quickly disposed in an edge to edge configuration to form walls, roofs, etc. The assembly time required to build a structure with modular building panels is typically much less than when building using conventional construction methods. The time and labor savings provides additional cost savings.
Structures built with modular building panels are often exposed to the wind, sun rain, hail, and even seismic activity. It is desirable that structures built with modular building panels be durable enough to withstand exposure to these elements.
When a building panel is struck by an object such as a hail stone or a rain drop, the panel will resonate. If a person is inside a structure built with a large number of panels, during a hail storm or rain, the level of sound created by the impact of precipitation on the building panels is often objectionable. For example, in many cases it is difficult to carry on a conversation in the room because of the noise. Since enclosed structures built with modular building panels are typically intended for leisure activities it is desirable that the space inside the enclosure provide a peaceful place to entertain guests.
SUMMARY OF THE INVENTION
The present invention relates to modular building panels utilized to fabricate cabanas, porches, and the like. A building panel in accordance with the present invention includes a first skin which is bonded to a first face of a first foam sheet. A second face of the first foam sheet is fixed to a cellular network. The cellular network includes a first face, a second face, and a plurality of cells defined by a plurality of cell walls. The second face of the cellular network is fixed to a first face of a second foam sheet. A second skin is bonded to a second face of second foam sheet. Applicant has found that a building panel in accordance with the present invention is less likely to produce an objectionable level of sound when struck by an object such as a hail stone or a rain drop. Applicant has also found that panels in accordance with the present invention possess desirable levels of strength and durability.
In one embodiment of the present invention, a wall may be formed which includes a plurality of building panels and a plurality of joining members. In an additional embodiment of the present invention, a wall may be formed by joining a plurality of building panels together in a snap-fit edge to edge configuration.
In one embodiment, of the present invention, the first skin may include a first portion, a second portion, and a third portion. The first portion of first skin is bonded to the first face of the first foam sheet. The second portion of the first skin extends beyond the first foam sheet and forms a first interlocking member. The third portion of first skin extends beyond the first foam sheet and forms a first complementary interlocking member.
The second skin of the building panel may also includes a first portion, a second portion, and a third portion. The first portion of second skin is bonded to the second face of the second foam sheet. The second portion of the second skin extends beyond the second foam sheet and forms a second interlocking member. The third portion of the second skin extends beyond the second foam sheet and forms a second complementary interlocking member.
