Abstract: The invention concerns a building element which is a stud (10) having a number of channels (12). Each channel can receive a cooperating means (14) which can be used to mount a panel or bracket on the stud. The invention also concerns a building element which is a joining clip (16) which can be connected to a panel or bracket. The joining clip includes the cooperating means (14) for mounting a panel or bracket on the stud. The invention also concerns a building element which is a joining element (42) which can connect one panel to another. The joining element is hinged (46). The invention also discloses two types of bracket for mounting in the stud. The first type has a screw-threaded shaft (71) and a sleeve (72) with cooperating means (73) at one end of the sleeve. The cooperating means is shaped so that it can be inserted horizontally in a channel of the stud and rotated so that the cooperating means cannot be withdrawn horizontally from the channel.

Abstract: A split-sphere observatory enclosure includes an antrum and a rotor including an oculus. The oculus is covered by an oculus window, which is rotatably mounted to the rotor.

Abstract: A wall panel supporting unit and system of constructing a wall utilizing a series of the wall panel supporting units in place of a traditional stud wall. The individual wall panel supporting units are of unitary construction and are generally rectangular. The units are corrugated and the resulting ridges function in the same manner as individual studs in a traditional wall, by creating a space within the wall for insulation, electrical wiring and similar uses. The individual units are fastened together, and attached to parallel tracks along the ceiling and floor to ensure a straight wall when panel sheathing such as drywall is applied. The individual units generally conform to each other when stacked together and offer a significant reduction in required shipping space.

Abstract: A roofing system incorporating lightweight concrete. The system includes a deck and an insulation board. Lightweight concrete is placed between the deck and the insulation board.

The lower flutes and channels form ribs in the concrete layer that strengthen the roofing system. The concrete layer may be attached to the deck by a series of protrusions in the deck that extend into the concrete. Alternatively, the concrete layer may float above the deck to prevent cracking. A release agent may be used to prevent the concrete layer from adhering to the deck.
