Abstract: A portable modular building structure that includes a plurality of sections assembled adjacent one another. The sections include molded fiberboard panels, that optionally include interior plenums. In an embodiment, each panel has an upwardly curving profile, and mirror-image sections are attached to one another via a fastener, that may include tape or other mechanical fastener. The sections are positioned end to end, with the number of sections determining the overall length of the structure. An optional end section of the structure may include wedge shaped sections positioned end to end, forming a curved end.

Abstract: A fiberboard panel is formed from at least one corrugated sheet of molded cellulose fiber material having alternating ribs and grooves. The corrugated sheet or panel is formed by a wet processing method including successive cold and hot press steps in which a wet mat is pressed between an opposing perforated platen and non-perforated, elastomeric material platen of cross-sectional shape substantially matching the desired panel shape and dimensions.

Abstract: Composite panels including core layers of particular geometry and optional first and second skin layers. The components optionally are made from fiberboard material. The core has either a linear geometry or made from discrete elements. In exemplary embodiments, longitudinally extending voids extend through the panel. Electrical or mechanical conduits may be inserted through the longitudinally extending voids.

Abstract: A three-dimensional structure comprising a plurality of substantially planar sections and an adhesive layer. The planar sections are oriented in stacked relation with one another. The adhesive layer binds the sections in substantially fixed relation with one another. In exemplary embodiments, the sections may be formed from a single piece or from plural pieces. The three-dimensional structure is formed by positioning the respective sections on a retainer and affixing them in place in relation to one another.
