An elevator system with a fire protection device includes an elevator shaft having at least two adjacent shaft portions, a guide rail in the elevator shaft, a car displaceable on the guide rail, and a fire protection device having a detector, a control unit connected to the detector, and a closing element that is disposed between two mutually adjacent shaft portions of the elevator shaft and which is movable between an open and closed state to separate the two shaft portions while in the closed state. A method of operating a fire protection device for an elevator system includes detecting smoke and/or a fire via a detector, and transferring a closing element disposed in the elevator shaft from an opened state to a closed state.

The composite assembly of the steel structure for lifting equipment comprised of the lifting system, into which the lower parts of vertically connected pillars connected to one another by cross-beams are fixed, with a levelling lifting system comprised of lifting plates (11) that are anchored into a concrete recess using chemical bonds via openings (15), with the structure levelling system comprising an adjusting screw (14), adjusting load-bearing nut (12), and safety nut (13), where the adjusting screw (14) passes through the opening in the lifting plate (10) welded onto the lower part of the lowermost pillar (1) of the structure. The vertical connections (3) of individual pillars (1), on the inner sides of both ends fitted with sets of openings mutually arranged at the angle of 90 degrees, are realized by inner connecting pieces (18) with fixed nuts (21), attached by Allen head screws (20) with safety washers having high resistance to spontaneous releasing due to vibrations via a set of openings. Connection of the cross-beam (2) and pillar (1), fitted with fixed integrated nuts (17), screw connections (4) is realized in the front part of the cross-beam (2) closed by the plate (4b) via oval openings (4a) on the inner side of the structure by Allen head screws (4c), supported by safety washers (4d) with high resistance to spontaneous releasing due to vibrations. The connections (4) are also fitted with mechanical protection by safety plates (7), attached by Allen head screws (22) to the fixed nuts (19) attached into the inside of the section on the side of the cross-beams (2), with corner reinforcements (6) ensuring the stability and perpendicularity of the connection (4) of the pillars (1) and cross-beams (2), further comprising a system for seating the brackets of the guide rails consisting of an oval opening (8) and a T-bolt (16), having a rectangular block (16b) in the rear part and a square block (16a) on the top of it for fixing and levelling the attached elements of the elevator.

A trench drain includes a trench, a grating seat and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and an outwardly-extending peripheral flange. The grating seat is configured to receive the grating. The peripheral side walls of the trench have a pair of opposing elongated slots formed therein and the grating has a pair of posts on opposing ends thereof. Each of the pair of posts on the grating are received in a respective one of the pair of opposing elongated slots of the trench to establish an axis of rotation.

A floor for use with a glass elevator is provided. The floor includes an upper major surface, a lower major surface opposing the upper major surface, a first side edge, a second side edge, the first and second side edges extending from the upper major surface to the lower major surface. The floor includes one or more front edges and one or more rear edges. The one or more front edges and one or more rear edges extend from the upper major surface to the lower major surface. The floor is formed from a unitary, continuous, solid plate material.

In accordance with the present invention, an elevator core structure includes an elevator frame (120) separated from a main frame (110) and extending in a longitudinal direction of the main frame (110), and a guide frame (130) formed on an inner surface of the elevator frame (120). Here, the elevator frame (120) may be formed by stacking a plurality of frame segments (121), and a guide frame unit (131) forming the guide frame (130) may be mounted to one surface of each of the frame segments (121). The present invention exhibits an effect of early-constructing the elevator frame regardless of a construction schedule of a main frame of a building.

A method for retrofitting a building using a lift system and a component kit for performing the method are provided. The shaft of the lift system extends over at least two stories 3 and comprises a self-supporting sheet metal box made of at least one steel plate, which is provided for receiving a cabin of the lift system together with its guides and drive devices. The sheet metal box of the shaft has a profiled cross section, which forms a cross-sectional area in the cross-sectional plane within the sheet metal box, which essentially covers the area required by the cabin and its guides and drive devices, and additionally contains the area of a lift platform for bridging a distance between the cabin and the building. The method provides prefabricating the lift system and installing it to the building.

An elevator system for installation on the outside of a building which extends over at least two stories and includes a shaft, a car movably mounted in the shaft for movement in a longitudinal direction of the shaft, and a drive for the car. The shaft has a shaft pit at its lower end and a through-opening for each story to be served and is configured as a prefabricated sheet-metal box made of at least one thin-walled steel plate that also extends beyond the shaft pit. The sheet-metal box forming the shaft is self-supporting, in that the steel plates extend in a straight line in the longitudinal direction of the shaft, and are profiled in a plane extending at right angles to the longitudinal direction. The steel plates are formed in one piece over the entire extent of the shaft in the longitudinal direction. A method for producing this elevator system is also provided.

A panel for a shaftwall system includes a panel body with a core and at least one outer facing layer and an opposite backing surface. A score line is formed in the facing layer, defining two folded panel portions. The panel is folded along the score line to form a folded edge, and the folded panel portions are arranged so that the backing surfaces of the panel portions contact each other. A companion shaftwall building structure system is provided, including a plurality of the panels defining an enclosure, each panel being a -inch thick wallboard panel having a V-shaped score line defining a pair of panel portions, the score line forms a tapered edge of the folded panel. A plurality of brackets is provided, each bracket defining a panel track dimensioned for slidingly accommodating the folded panel and retaining the panel in place without the use of fasteners.

A trench drain includes a trench, a grating seat and a grating hingedly connected to the trench.
