A lean-to rigging apparatus is described for installation in a shaft, such as an elevator shaft, having a wall and including at least one sill opposite the wall. The rigging apparatus includes a spanning beam, a sill support structure, a wall support member, and a hoist connector. The sill support structure on a first end of the spanning beam is designed to seat against a sill in the in the shaft while the wall support member on a second end of the spanning beam abuts against the opposite shaft wall. The sill support structure is rigidly connected to the spanning beam in a hingeless configuration and can seat against a sill in a plurality of seating positions. These seating positions allow the rigging apparatus to be positioned in a plurality of angles and therefore to be installed in shafts of different dimensions. The hoist connector is configured to allow a connection to a hoist device for hoisting various materials from one level to another within the shaft.

An improved apparatus for conditioning the temperature of the air in a substantially confined space, such as a room, is disclosed. The conditioning system is complete and integrated in a portable unit suitable for insertion in a wall opening, such as a window. The operative elements are divided between two separate enclosures, each attached to a common structure, the support capable of resting on the window sill, with one such enclosure on each side of the wall. At least the heat exchanger conditioning room air is disposed in the enclosure in the room side of the wall. At least the compressor is segregated in the other enclosure, on the other side of the wall of the conditioned space. And both enclosures sit substantially below the sill line. Obstruction of the window opening is much reduced over prior art units. Installation is easier and safer. And the segregation of the compressor, which can be improved by sound and vibration dampening treatments, drastically reduces the noise level in the room produced by the system's operation.

A composite wall assembly has an auxiliary wall and an inner wall. The auxiliary wall has a hollow space and a first supporting pillar having multiple first through holes. The inner wall is attached to the auxiliary wall and forms a depositing space. The inner wall has a first wall member, a second wall member, and a second supporting pillar having multiple second through holes. The depositing space is formed between the first wall member and the second wall member. The auxiliary wall provides a cushion effect and is not damaged easily in the earthquake for protecting the pipelines in the hollow space. The interior ambient temperature of the building is lowered by the hollow space of the auxiliary wall.

The present invention relates to a lintel or angle iron cover, and specifically a cover for an L-shaped lintel having a rise portion and a run portion. The cover is also L-shaped and is a continuous wall made up of an upper wall joined to a top wall which is joined to a side wall. The side wall is also joined to a bottom wall which is joined to a back wall. Further, the upper wall is at least as high as the rise portion of the lintel. The top wall and bottom wall form a U-shaped opening closed by the side wall, and the U-shaped opening is the size of the run portion. Whereas the back wall forms a lip at the end of the bottom wall.

A truss bracing system for roof trusses is disclosed. The truss bracing system comprises of a lateral brace and a diagonal brace connected through a pivot point. Both the lateral brace and diagonal brace include a first support member and a second support member where the first support member is angled relative to, and preferably perpendicular to, the second support member. The pivot point allows the diagonal brace to rotate relative to the lateral brace. That is, the truss bracing system has a closed configuration with the diagonal brace resting adjacent and parallel to the lateral brace and an extended configuration with the diagonal brace rotated relative to the lateral brace, such that the diagonal brace is angled relative to the lateral brace. Thus, the truss bracing system provides both lateral and diagonal support to the trusses to which it is attached.

Systems and methods for assembling structural components are disclosed. The systems and methods consider a sequence, operations of the sequence, and an approach vector in placing structural members (including structural members with pre-attached fasteners) for assembling structural components.
