Abstract
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 stub-up for being anchored to concrete slab flooring in which conduit is embedded therein and through which electrical wiring may be extended, comprising a one-piece hollow body having an upper end providing an electrical box and a lower end providing a base permitting said hollow body to be anchored to an underlying concrete slab in an upstanding position, wherein the hollow body provides a wireway for electrical wiring from the slab to the electrical box.
A building structure, comprising:
- a concrete slab floor in which an in-slab conduit is embedded for the passage of electrical wiring therethrough, the in-slab conduit has a bell end adjacent an upper surface of the concrete slab floor;
- a wall formed on the concrete slab floor such that the bell end of the in-slab conduit is located within the wall;
- and
- a stub-up anchored to the concrete slab floor within the wall over the bell end of the in-slab conduit, the stub-up comprising a hollow body having an upper end providing an integral electrical box and a lower end providing a base anchored to the upper surface of the concrete slab floor such that the stub-up is in an upstanding position, the hollow body providing a wireway for electrical wiring from the bell end of the in-slab conduit to the electrical box of the stub-up.
A method of installing a conduit stub-up, comprising the steps of:
- providing a one-piece hollow body having an upper end providing an electrical box and a lower end providing a base such that the hollow body provides a wireway for electrical wiring from an underlying concrete slab to the electrical box;
- positioning the hollow body on a surface of a concrete slab over an exposed bell end of conduit embedded in the concrete slab for the passage of electrical wiring therethrough;
- and
- anchoring the lower end of the hollow body to the concrete slab so as to position the electrical box at a desired located above the surface of the concrete slab.
