摘要： A screeding machine includes a base unit positionable at framework that defines a concrete structure and a screed head assembly movably mounted at the base via an extendable and retractable mechanism. The screed head assembly includes a grade establishing member, a vibrating member, and elevation actuators for adjusting elevation of the screed head assembly. The screed head assembly is positioned at a screeding location via extension of the extendable and retractable mechanism and is movable over the uncured concrete in a screeding direction via retraction of the extendable and retractable mechanism. Adjustable wings disposed at and in front of the grade establishing member in the screeding direction are movable along the grade establishing member. When one of the ends of the screed head assembly is positioned at a frame portion, the wing at that end of the screed head assembly is moved to position the wing at the frame portion.

摘要： A decorative concrete structure simulating natural wood and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is swept with a broom, saw cut, and optionally stained, and sealed to simulate aesthetic appearance of the natural wood.

摘要： A cement screeding system in the form of a powered roller screed with a wet screed attachment. The wet screed attachment includes a wet screed shoe. A handle is rotationally isolated from the screed roller and is rigidly coupled to this wet screed shoe. As such, motion of this handle is transmitted to the wet screed shoe in a replicating fashion.

摘要： A concrete floor leveling device includes a transmission device and a power source is located in a body and connected to wheels which are connected to the body. A connection unit is connected to the body and a blade is connected to the body by the connection unit. The power source outputs a stable power to drive the blade to level the concrete floor and to ensure that the blade levels the concrete floor with even force.

摘要： A screed machine is formed with a forwardly positioned screed assembly including a wedge portion and pivoted wing members. The frame is supported on two rollers spaced behind the screed assembly, which is mounted on a mast for vertical movement in conjunction with a laser receiver that provides a signal from a laser level indicating the final desired grade of the stone base. The machine can be turned at a corner by extension of a jack stand to elevate the machine for rotation about the axis defined by the centrally located jack stand so that the screed machine can be redirected into a different direction without disturbing the final grade of the stone base. The screed machine is manually moved along the stone base by an operator pulling on the handle pivotally connected to the frame. A sight line provides a monitor for the lateral orientation of the screed assembly.

摘要： A sidewalk grader provided for grading a sidewalk base disposed along a curb of an existing road structure. The sidewalk grader comprises a tracking assembly fixable to a vertically adjustable backfill blade of a compact excavator positioned to move forward over an existing road structure to advance the sidewalk grader. The tracking assembly comprises a vertically adjustable tracking means disposed for engagement with the top surface of the curb, to provide a reference point. A grading assembly is mounted to the tracking assembly. The grading assembly comprises a frame, and a grading blade rotatingly mounted to the frame to permit adjustment of slope of the blade. An adjustable link connects the grading blade to the frame to adjustable fix their relative position. The tracking means is vertically adjustable to enable the same to engage with the surface of a curb for reference to enable precise adjustment, control, and positioning of the grading assembly, and for maintaining the desired position of the sidewalk grader in relation to the curb as the sidewalk grader advances along the existing road structure.

摘要： A device that is used to pull a stake from a newly poured concrete slab. This device allows for attachment to a concrete pole, a tool that is commonly possessed and used by most concrete contractors. It contains a flexible loop that is used for the removal of stakes from the inside of a perimeter of a newly poured concrete slab. The loop of the device is placed so that it encircles the shaft of a concrete stake. A worker rotates the concrete pole until the loop twists enough to tightly hold onto the stake. The stake is then pulled from the ground and lifted up, over, and to the outside of the perimeter of the slab. The invention may include adjustment means to allow its efficient use with stakes of different thickness.
