Abstract
A concrete finishing assembly includes a plurality of rails that each has a guide surface. A plurality of couplers each releasably engages a respective pair of the rails for attaching the respective pair of rails together. In this way the plurality of rails defines a border to surround a shower floor. A cylinder is provided and the cylinder can be inserted into a drain in the shower floor. A trowel unit is provided that has an adjustable length and the trowel unit is attachable to the cylinder. The trowel unit is slidable along the guide surface of the plurality of rails that defines the border. In this way the trowel unit can smooth concrete on the shower floor at a predetermined slope for draining water into the drain.
Claims12
A concrete finishing assembly for smoothing a sloped shower floor, said assembly comprising:
- a plurality of rails, each of said rails having a guide surface and a bottom surface wherein said bottom surface is configured to rest on a support surface;
- a plurality of couplers, each of said couplers releasably engaging a respective pair of said rails for attaching said respective pair of rails together thereby facilitating said plurality of rails define a border wherein said border is configured to surround a shower floor;
- a plurality of hinged couplers, each of said hinged couplers comprising a first half being hingedly coupled to a second half, each of said hinged couplers releasably engaging a respective pair of said rails for attaching said respective pair of rails together thereby facilitating said plurality of rails define a border wherein said border is configured to surround the shower floor;
- a cylinder being configured to be inserted into a drain in the shower floor;
- a trowel unit having an adjustable length, said trowel unit being attachable to said cylinder, said trowel unit being slidable along said guide surface of said plurality of rails that defines said border wherein said trowel unit is configured to smooth concrete on the shower floor at a predetermined slope for draining water into the drain;
- and
- wherein said trowel unit includes a trowel having a primary end, a secondary end and an outer wall extending therebetween, said outer wall having a top side, a bottom side, a first lateral side and a second lateral side, each of said first lateral side and said second lateral side angling inwardly between said bottom side and said top side such that said trowel has a trapezoidal cross section taken along a line extending through said primary end and said secondary end.
