An apparatus for steering and driving a concrete screed having a frame and a screed head secured thereto includes a plurality of spaced drive wheels rotatably and pivotably secured to the frame at a plurality of points, and a steering member coupled to one or more of the drive wheels for controlling the directional orientation thereof.

An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a front end and rear ends and a pair of spaced vertically oriented stabilization legs supporting a generally horizontal front member. An extendable boom assembly is provided having front and rear ends, and an exterior boom section pivotably secured to the frame assembly proximate said rear end. The extendable boom assembly is also adjustably mounted on said front member to allow generally lateral motion of the boom.

A method including placing a screed hardware unit upright on a surface. The hardware unit includes a base and a post. The base is fastened on the surface such that the post extends vertically from the base. The method further includes adjusting a height of the hardware unit so as to be consistent with a desired grade. Concrete is poured up to and/or around the hardware unit, and the concrete is screeded at the grade indicated by the height of the hardware unit.

An apparatus including a base. The base includes a post mount portion disposed on a first side of the base. The apparatus further includes an adhesive member that attaches to a second side of the base. The adhesive member includes an adhesive and a cover disposed on the adhesive. The cover is removable to expose the adhesive. A post having a distal end and a base end is attachable to and detachable from the base member at the post mount portion.

A concrete screeding tool includes an elongated stake, a disk, and a bar. The stake has a longitudinal axis, an outer surface, a first end, and a second end. The disk extends radially from the outer surface. The bar is spaced from the outer surface and is parallel to the longitudinal axis. Slurry depth is measured by vertically positioning the concrete screeding tool spaced from an outer frame; pouring a slurry into the frame; placing a screeding board between the bar and the elongated stake and on the outer frame; and leveling the slurry with a sawing motion. The tool is small and durable, is easy to set up and clean, prevents dips in concrete, makes bull floating concrete easier, and can save man hours in screeding the concrete level.

A connection assembly for connecting a bolt to a slab includes a first connection part and a second connection part. The first connection part and the second connection part may be capable of being assembled to the slab in a manner so as to sandwich the slab with a first clamping member of the first connection part and a second clamping member of the second connection part between two opposite surfaces of the slab. The first connection part and the second connection part may be connected in a manner such that a connection between a first hollow-tubular-connecting-structure of the first connection part and a second hollow-tubular-connecting-structure of the second connection part may be within a through-hole in the slab, which extends between the two opposite surfaces of the slab.
