An apparatus for leveling a concrete screed having a frame and a screed head secured thereto includes a plurality of vertically adjustable leveling legs driven by a plurality of electrical actuators responsive to a command supplied by a user interface.

A pair of articulating screed framework extensions, independently adjustable at least two locations along each extension, independently adjusting each extension to a comfortable working height and other subjective needs of each user, each extension providing an upper plate on a first section, a hand grip on a second section and distal end on a third section to which a screed workpiece is independently attached to locate a width between each extension, with a locking pivot joint between each first and second section and each second and third section.

A concrete screeding apparatus for a wall captured concrete pour includes a round screed rail with a top edge that defines the level of the screeded concrete, and a stake base assembly with a rail support for holding the screed rail. A rebar stake is driven into the soil through the stake base assembly, and a rail support sits atop the rebar stake.

Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

A hand tool. The hand tool includes the hand tool includes a shank, a handle attached to the shank, and a finishing element attached to the shank. The finishing element is attached to the shank by one or more fasteners. The fasteners extend substantially through a hole in the finishing element and an aligned hole in the shank to affix the finishing element to the shank. The fastener has a first expanded end situated in a countersink in an exposed surface of the shank.

A stair step jig assembly for smoothing treads on concrete steps includes a jig that is elongated to a predetermined length to extend along a full length of a tread on a concrete step for smoothing the tread before the concrete has cured. A riser adjustment is hingedly coupled to the jig and the riser adjustment unit abuts a concrete form that is positioned against the riser of the step adjacent to the tread upon which the jig is positioned. A leg is hingedly coupled to the jig and the leg slidably engages the riser adjustment such that each of the leg, the riser adjustment and the jig forms a triangle. The leg has engages a top of the riser of the step adjacent to tread upon which the jig is positioned for keeping the jig at a fixed angle on the tread.

Electronic trowels, systems and methods of applying a layer of material using the present electronic trowels. The various electronic trowels include a handle, at least one blade, and one or more sensors residing on or within the trowel. The trowel is for applying a layer of material over a surface area, whereby the one or more sensors detect and collect material installation data during application of the layer of material over the surface area. One or more electronic devices coupled to the one or more sensors receive and analyze the collected installation data for monitoring and controlling the application of the layer of material to ensure a desired end product is achieved. Application errors may be detected before, during, or after the installation process.

A hand-held screed rake and method for spreading paving material using the hand-held screed rake. The hand-held screed rake includes a screed head having a paving surface and a heating element coupled to the screed head and configured to heat the paving surface.

An accessory for levelling uncured concrete surfaces. The accessory includes a screed head with two height adjusting levelling cylinders (1), a slope cylinder (2), a coupling component (3), a blade (4), an auger (5), a roller (6), a vibrator (7) and a sprinkler system (8). The coupling component (3) includes a hand operated hinged latch with a hook able to be snapped in place in a single movement so as to pinch together the coupling component and a telescopic boom of a general-purpose vehicle. The slope cylinder (2) enables the screed head to be maintained continuously at ninety degrees to the horizontal.

A combined bull float-roller concrete finishing device including a bull float member and a roller member. The bull float member including a handle and a blade. The bull float member is configured to smooth an underlying surface. The roller member including a pair of rotatable attachment bars which are each connected to the blade in a perpendicular orientation at a right and left side of the blade respectively. A roller is attached between the pair of attachment bars. The roller member is configured to rotate the roller downward to a position behind a rear end of the bull float member to roll the roller over an underlying surface and is configured to rotate the roller upward to a position above the bull float member to prevent the roller from rolling over an underlying surface.
