Description

FIELD OF THE INVENTION

The present invention relates to a building device for covering a plurality of beams.

More specifically, the present invention relates to a building device for covering a plurality of beams in which each beam is disposed parallel to an adjacent beam.

BACKGROUND OF THE INVENTION

In the building industry, a roof includes a number of roofing trusses. More specifically, in a simple roof configuration, each truss is disposed parallel to an adjacent truss.

A typical roofing truss includes a horizontally disposed ceiling joist and a first and a second rafter extending from opposite ends of the ceiling joist to a roof ridge.

When the roofing trusses have been installed, the normal roofing operation includes nailing sheets of roofing material such as oriented strand board (OSB) to the rafters. When the roofing sheets have been secured to the rafters, tar paper is laid and nailed to the upper surface of the roofing sheets. Metallic edging strips are then attached to the peripheral edges of the roof. Finally, roofing shingles are nailed to the roofing sheets so that the tar paper is disposed between the roofing sheets and the shingles.

Needless to say, the aforementioned roofing operation is labor intensive and thus relatively costly.

Additionally, with the ever increasing demand for solar heating of buildings, the cost of roof construction has become a major portion of the overall construction cost of a building.

The present invention provides a unique system which greatly reduces the time and expense associated with roof construction while at the same time providing the basic requirements for the optional installation of items such as a solar heating system and allowing the capability of attaching and routing various utility and building materials.

Therefore, it is a primary feature of the present invention to provide a building device for covering a plurality of beams that overcomes the problems associated with the prior art arrangements.

Another feature of the present invention is the provision of a building device for covering a plurality of beams that greatly reduces the cost of fabricating a roof.

Another feature of the present invention is the provision of a building device for covering a plurality of beams that greatly reduces the cost of fabricating a flooring system.

Other features and advantages of the present invention will be readily apparent to those skilled in the art by a consideration of the detailed description of a preferred embodiment of the present invention contained herein.

BACKGROUND INFORMATION

In the present invention, the labor intensive steps of nailing roofing sheets is avoided together with the cost of purchasing such roofing sheets. Also, the step of nailing tar paper is no longer required.

Furthermore, with the arrangement according to the present invention, no edging strips and their installation is required.

Above all, no shingles are required together with the relatively expensive operation of aligning and nailing such shingles to the roofing sheets.

Another advantage of the roofing construction according to the present invention is that in a conventional roof with roof shingles, such shingles must be replaced on an average every twenty five years. However, with the arrangement according to the present invention, the roofing will last indefinitely.

Additionally, the device according to the present invention is also applicable to a flooring system and would incorporate means for circulating a fluid such as heated water for providing under floor heating, being able to add utilities, and capabilities to add additional building materials to the device.
