Publication number: 20230332361Abstract: A concrete surface working machine includes a base portion and a screed head mounted at the base portion. The screed head includes a grade setting device and a vibrating element attached at a frame of the screed head. The screed head includes a rock tamper adjustably attached at the frame of the screed head via a pair of support elements. The screed head includes a pair of actuators that, when actuated, adjust the support elements to adjust the rock tamper relative to the frame. The concrete surface working machine is operable to position the vibrating element at the concrete surface. The actuators are selectively controlled by an operator of the concrete surface working machine to adjust a height of the rock tamper relative to the vibrating element and the concrete surface while the screed head is moved along the concrete surface.Type: ApplicationFiled: April 12, 2023Publication date: October 19, 2023Inventors: Philip D. Halonen, Mark A. Pietila, James E. Kangas, Matthew A. Kangas

Publication number: 20220064971Abstract: 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.Type: ApplicationFiled: August 26, 2021Publication date: March 3, 2022Inventors: Philip D. Halonen, James E. Kangas, Matthew A. Kangas, Mark A. Pietila

Publication number: 20210131042Abstract: A method for screeding an uncured concrete surface includes providing a screeding machine having a screed head assembly movable over the concrete surface. A pair of elevation sensors disposed at opposite ends of the screed head assembly sense an elevation of the respective end of the screed head assembly. An angle sensor disposed at the screed head assembly senses a pitch angle and/or a roll angle of the screed head assembly. A gyroscope sensor disposed at the screed head assembly senses rotational velocity of the screed head assembly about a lateral axis and/or a longitudinal axis of the screed head assembly. A control determines pitch angle and/or roll angle of the screed head assembly. The control controls the screed head assembly based on the signals from one or both of the elevation sensors and the determined pitch and/or roll angles.Type: ApplicationFiled: January 15, 2021Publication date: May 6, 2021Inventor: Matthew A. Kangas

Patent number: 10060900Abstract: A method for screeding of an uncured concrete surface includes providing a screeding machine and a control. The uncured concrete surface is screeded and the control processes data captured by the sensors while the screeding machine is screeding the uncured concrete surface. While the screeding machine is screeding the uncured concrete surface, and responsive to data processing by the control of data captured by the sensors while the screeding machine is screeding the uncured concrete surface, the control estimates a flatness or levelness or quality of the surface of the concrete surface being screeded. The control may generate an output indicative of the estimated flatness or levelness or quality of the surface, and/or a display may display information associated with the estimated flatness or levelness or quality of the surface.Type: GrantFiled: December 4, 2017Date of Patent: August 28, 2018Assignee: SOMERO ENTERPRISES, INC.Inventor: Matthew A.

Patent number: 9835610Abstract: A screeding system for use with a screeding machine during screeding of an uncured concrete surface includes a control and a plurality of sensors. The sensors are disposed at the screeding machine, which has a screed head assembly that is movable over uncured concrete to screed the concrete surface. The sensors include elevation sensors that sense an elevation of the screed head assembly relative to a reference plane established at the concrete area. The control processes data captured by said plurality of sensors while the screeding machine is screeding the uncured concrete surface. Responsive to the data processing of captured data, the control estimates a flatness or levelness or quality of the surface of the concrete being screeded. While the screeding machine is screeding the uncured concrete surface, the control generates an output indicative of the estimated flatness or levelness or quality of the surface.Type: GrantFiled: April 28, 2015Date of Patent: December 5, 2017Assignee: SOMERO ENTERPRISES, INC.Inventor: Matthew A.
