A floor and column structure consists of floors and columns in a building, wherein each of the floors is composed of a floor iron sheet, square pipes, a floor steel grating, a lower impermeable membrane, rigid plastic foam, an upper impermeable membrane and cement stone concrete; each of the columns is composed of a column iron sheet, column steel gratings, steel posts and cement stone concrete; the floor iron sheet, the square pipes and the floor steel grating and the column iron sheets, the column steel gratings and the steel posts are welded into a framework; the lower impermeable membrane, the rigid plastic foam and the upper impermeable membrane are provided over the floor steel grating; Various pipelines are installed in the plastic foam layer; the cement stone concrete is provided over the upper impermeable membrane; and a colored cement talc layer is provided over the cement stone concrete. The inventive floors and columns do not need to be supported and reinforced by concrete beams, do not need to be enclosed by supporting timber boards during casting, can isolate vibration, insulate sound and heat, greatly shorten engineering time, prevent leakage, and facilitate pipeline installation, have smooth, bright, visually pleasant, sanitary and freshening surfaces, and can replace floors and columns in existing large buildings and be applied to the construction field.

An electrical cord receiving anti-fatigue mat assembly includes a panel that has a top side, a bottom side and a perimeter edge. The panel is comprised of a resiliently compressible material. The bottom side has a trough therein with the trough having a pair of ends each comprising an opening extending through the perimeter edge. The trough receives an electrical cord such that the bottom side abuts and is flush with a floor surface when the electrical cord is positioned within the trough and extends through each of the openings. The trough has a depth and width each being greater than 0.40 inches.

A stub-up is provided for being anchored to concrete slab flooring in which conduit is embedded and through which electrical wiring may be extended. The stub-up comprises a one-piece hollow body having an upper end providing an electrical box and a lower end providing a base permitting the hollow body to be anchored to an underlying concrete slab in an upstanding position. The hollow body provides a wireway for electrical wiring from the slab to the electrical box. Wall structures and methods are also disclosed.

A track assembly for a rail-mounted component of a vehicle includes a rail cartridge slidably coupled with a track and defines a first slot. A first electrical connector is positioned within the rail cartridge. A connection cartridge defines a channel. The connection cartridge includes first and second sidewalls joined by a bottom wall. A second electrical connector is positioned within the channel and is configured to selectively engage with the first electrical connector. An actuation member is positioned within the channel and is movable between first and second positions. The actuation member is biased to the first position. An actuator is operably coupled with the actuation member to selectively move the actuation member into the second position against the bias.

There are provided a fixing structure for corrugated tube and a fixing method for corrugated tube including a corrugated tube that is extensible and contractible in a longitudinal direction of the corrugated tube, and through which a wiring is inserted; and a plurality of fixing members configured to fix the corrugated tube through which the wiring is inserted to a plurality of fixing locations provided at a fixing destination, the fixing members being attached to an outer surface of the corrugated tube at a certain interval along the longitudinal direction. The corrugated tube is extended or contracted between adjacent fixing members of the plurality of fixing members, and the adjacent fixing members are adjusted to be at an interval corresponding to a different interval at which the plurality of fixing locations are arranged, such that the plurality of fixing members are fixed to the plurality of fixing locations.

A track assembly includes a rail cartridge slidably coupled with a track. A first electrical connector is positioned within the rail cartridge. A connection cartridge defines a channel and includes a second electrical connector configured to selectively engage with the first electrical connector. An actuation member is positioned within the channel of the connection cartridge and is coupled with the second electrical connector. A spring is operably coupled to the actuation member and is configured to bias the actuation member in a first position. An actuator is operably coupled with the actuation member. The actuator is moved upward against the bias of the spring to move the actuation member to a second position when the actuator contacts the rail cartridge of the track.

A system for transmitting electrical energy from an energy source to a consumer, e.g., for contactlessly transmitting energy to a mobile consumer, includes a first line conductor and a second line conductor. Each line conductor has, in a respective axial direction, an at least approximately rectangular cross-section, the long sides of which are longer than the broad sides. The axial directions of the line conductors extend at a right angle with respect to a vertical direction. The first and second line conductors intersect in an intersection region in which a holding device is arranged, and are arranged outside the holding device such that the long sides of the line conductor cross-sections are parallel to the vertical direction. The first and second line conductors are arranged in a central region of the holding device such that the long sides of the line conductor cross-sections are oriented at a right angle with respect to the vertical direction.

A track assembly includes a rail cartridge slidably coupled with a track. A first electrical connector is positioned within the rail cartridge. A connection cartridge defines a channel and includes a second electrical connector configured to selectively engage with the first electrical connector. An actuation member is positioned within the channel of the connection cartridge and is coupled with the second electrical connector. A spring is operably coupled to the actuation member and is configured to bias the actuation member in a first position. An actuator is operably coupled with the actuation member. The actuator is moved upward against the bias of the spring to move the actuation member to a second position when the actuator contacts the rail cartridge of the track.

A raceway formed of an elongated track member, the track member having at least one elongated passage adapted to receive one or more cables, the at least one elongated passage located intermediate end channels on each side of the track member, a cover for enclosing the cables within the elongated passage of the track member, and a channel member associated with each end channel. The channel member is user determinable with at least a portion of the channel member residing in the end channel.
