ABSTRACT:
An apparatus for installing wooden deck planks on a supporting frame of joists has an actuator mounted on a base plate with an output shaft movable between an open position and a closed position. A control device is mounted on the frame for selectively controlling the actuator to move the output shaft. A fixed angle clamp is mounted on the base plate and has a leg for engaging an edge of a first deck plank, a sliding angle clamp is attached to the output shaft and has a leg for engaging an edge of a second deck plank, and a spacer plate is slidably mounted on the base plate between the clamps and has a predetermined thickness corresponding to a desired spacing between adjacent deck planks. When the actuator moves the output shaft to the open position, the base plate can be rested on the upper surfaces of the first deck frame and the second unattached deck plank with the fixed angle clamp leg engaging the opposite edge of the first deck plank and the spacer plate extending between the facing edges of the deck planks. When the actuator moves the output shaft to the closed position, the sliding angle clamp engages the opposite edge of the second plank and the spacer abuts the facing edges of the first and second planks.
