A method for creating an elevator shaft for an elevator system, wherein the elevator shaft is oriented mainly vertically, uses a plurality of base modules placed on one another. The shaft is upwardly closed off by a top module and forms a travelway for a car of the elevator system. In a normal operation of the elevator system, the car is moved at a nominal speed within the travelway. According to the method, an intermediate element having an intermediate element height is arranged between an uppermost one of the base modules and the top module, wherein the intermediate element height is dependent on the nominal speed of the car.

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 and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and the trench defines a trench volume therein. 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.

An elevator trench drain includes a trench and a drain passageway. The trench has a base wall with peripheral side walls extending upwardly therefrom to define a trench volume therein. The drain passageway extends downwardly from the base wall of the trench and places the trench volume in fluid communication with a lower opening of the drain passageway. The drain passageway has a first section proximate the base wall defining a first cross-sectional area and a second section distal the base wall defining a second cross-sectional area. The second cross-sectional area is less than the first cross-sectional area and this reduction in cross-sectional area produces a head pressure that increases the flow out of the lower opening.

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.

With a view to a quick and safe construction of an elevator using structurally simple and cost-effective means, a method for constructing an elevator in particular, a freight elevatoron a construction site, and preferably in a factory hall. The elevator is built from several components arranged one atop the other. The method includes providing a base for the elevator; positioning a lifting device on the base; raising an upper component of the elevator by way of the lifting device; positioning a lower component, which is to be arranged underneath the upper component, under the raised upper component; lowering the upper component onto the lower component by way of the lifting device; and removing the lifting device from the base. Further specified is an elevator constructed according to said method.
