Abstract: A composite building system comprising a structural frame and walls which is made of pultrusion fiber reinforced polymer (PFRP) material. PFRP provides increased performance, strength, protection, and longevity for mobile and fixed building structures, enclosures or vehicles, commonly found in residential, commercial, industrial, healthcare, aerospace, government defense, energy, and agriculture sectors. The PFRP material comprises fibers embedded in a resin matrix. Exemplary fibers are glass, carbon, and synthetic fibers. PFRP products can be formed using a pultrusion method that eliminates outgassing. An intumescent fire barrier can be applied to the PFRP to meet National Fire Protection Association fire endurance codes and standards. The composite building system increases personal safety while reducing weight, labor costs, construction time, and total cost of ownership over the life of the structure while being resistant to ballistic, seismic, corrosion, rotting, impact, and insect damage.

Abstract: The present invention is a framing component interconnecting device that is particularly useful for interconnecting a spanning member and its supporting components. While the device may be used in a number of ways to facilitate frame construction, the preferred mode of use is to pre-attach it at the bearing points of a spanning member during pre-assembly of the spanning member. Because the device is not obtrusive while it is in what is referred to herein as a “non-deployed configuration,” the device thus attached to a spanning member does not hinder or complicate storing, transporting, and handling the spanning member. The device incorporates an anchor strap and connecting flaps that can be deployed in order to interconnect the spanning member to its supporting component once the spanning member has been raised into position. In its deployed configuration, the device anchors, orients, braces, and interconnects one framing component to another.
