Abstract: To this end, the present invention comprises a headgear apparatus comprising a sleeve, a first strap portion and a second strap portion. The sleeve comprises a chin portion and a top portion. The top portion is integrally connected to the chin portion. The first strap portion is connected to a first part of the sleeve near the top portion. The second strap portion is connected to a second part of the sleeve near the chin portion. A nosepiece may be fastened to the headgear apparatus via the first strap portion and the second strap portion.

Abstract: A reinforced structural member for connection to a building panel, such as a pre-fabricated building panel used to construct walls, floors and roofs of a building. The reinforced structural member is a two-piece assembly comprising a structural member and a reinforcing member. The reinforcing member is fastened to the structural member such that a plurality of projections extending from the reinforcing member engage the building panel. The reinforced structural member is especially adapted for use with composite or cementious materials, such as concrete. The reinforcing member substantially reinforces the structural member, while the projections on the reinforcing member securely embed within the concrete building panel. A U-shaped track, having projections which embed within the building panel, also may be used to brace the reinforced structural members relative to each other and to the building panel.

Abstract: A structural building module has first and second upright cast structural members. Each of the first and second structural upright members include a wall portion and a roof portion. These structural members are initially supported on erection pads such that the wall portions are upright and the roof portions project toward one another such that the roof portions can be joined together. After joining the roof portions a structural base is formed in situ by casting. The structural base is attached to the wall portions of the structural members by entraining into the structural base, attaching members projecting out of the wall portions near their bottom edge.
