Abstract: An electrical conduit support post includes a rigid pipe that penetrates through a roof deck and a pipe boot that surrounds the rigid pipe. A mounting plate is fixed to a bottom end of the pipe boot for attachment to the roof deck with screw fasteners. Flashing is applied to cover and seal the mounting plate and the penetration through the roof deck, and an approved sealant is applied around the base of the pipe boot above the flashing. Electrical conduit extends through the rigid pipe from an interior of a building structure, through the roof deck and exits a cap that is sealed to the top end of the rigid pipe at an adjusted height above the roof deck.

Abstract: A roof curb extension includes an integral one-piece body having a lower end portion with a flashing for attachment to an existing curb and an upper portion defining a new curb and a central portion structured and configured for enlarging or reducing the size of the new curb for matching roof equipment to the new curb without disturbing the integrity of the existing roof.

Abstract: A construction safety screen system includes a flexible net member sized to cover an opening of a building, a plurality of straps attached to the flexible net member, and a plurality of oval snap hooks each being securable to the distal end of one of the plurality of straps and to one of a plurality of fasteners attached to the concrete building structure surrounding the opening.

Abstract: A device for use in the installation of lightweight concrete roof systems includes a base element having a substantially flat portion and a wire tie. The wire tie extends from the base element and terminates at opposite ends which may be formed in a ring or loop. In use, the base element is mechanically fastened to the bar joist, through the steel deck, of the roof system. The terminal ends of the wire tie are secured to steel-welded wire reinforcement fabric overlying a layer of lightweight concrete, thereby securing the lightweight concrete to the steel deck of the roof system and preventing separation of the lightweight concrete due to external forces such as wind sheer.

Abstract: A traffic signal apparatus is provided with solar panels, a battery source for powering light directional signals during a power outage and a charger linked to the solar panels for re-energizing the battery source. Changing of the light directional signals (i.e. red, yellow, green, arrow) is controlled by a timer connected to the battery power source. In a preferred embodiment, one or more 12 volt batteries, such as those used in an automobile, are connected in series for powering the light signals. The batteries, solar panel(s), charger, connecting cables and the timer may be installed to an existing conventional traffic light signal or, alternatively, on a temporary traffic light signal supported on a post for placement on the ground, preferably in the middle of the road, such as at an intersection.
