Abstract
An elevator pit includes a concrete body and a water-resistant coating. The concrete body is pre-cast from a single pour of concrete and includes a lower surface, an upper surface, and an exterior surface extending between the lower surface and the upper surface. The lower surface is configured to be seated directly against a ground surface. The upper surface is opposite the lower surface and includes an opening that communicates with a main recess that extends toward the lower surface. The main recess is configured to receive one or more components of an elevator system. The water-resistant coating is applied continuously and in a single session to the lower surface and the exterior surface.
Claims20
An elevator pit comprising:
- a concrete body pre-cast from a single pour of concrete, the concrete body including:
- a lower surface that is configured to be seated directly on a ground surface,
- an upper surface that is opposite the lower surface,
- wherein the upper surface includes an opening that communicates with a main recess that extends toward the lower surface,
- wherein the main recess is configured to receive one or more components of an elevator system, and
- an exterior surface that extends between the lower surface and the upper surface;
- and
- a water-resistant coating applied continuously and in a single session to the lower surface and the exterior surface.
An elevator pit assembly comprising:
- an elevator pit pre-cast from a single pour of concrete, the elevator pit including:
- an upper surface that includes a first opening,
- a lower surface that includes a second opening that communicates with the first opening to define a through hole,
- wherein the through hole includes:
- a main recess, and
- a sump pit recess,
- an exterior surface that extends between lower surface and the upper surface;
- and
- a sump pit seated within the sump pit recess.
A method comprising:
- casting, with a single pour of concrete and at a first location, a concrete body of an elevator pit,
- wherein the concrete body includes:
- a lower surface,
- an upper surface that is opposite the lower surface,
- wherein the upper surface includes an opening that communicates with a main recess that extends toward the lower surface,
- wherein the main recess is configured to receive one or more components of an elevator system, and
- an exterior surface that connects the upper surface and the lower surface;
- and
- installing, at a second location different than the first location, the elevator pit such that the lower surface directly contacts a ground surface.
