  • Publication number: 20090103978
    Abstract: An apparatus, method, and system are disclosed, which provide a means of real time surface profile evaluation in wet cement. The sliding profiler can be pulled behind various stages in a paving train. The user is alerted to profile discrepancies while the cement is still pliable and afforded the opportunity to make adjustments to the paving process, to include additional finishing. The system is made of affordable components and thus is appropriate for construction projects of different scale. In addition, multiple sliding profilers can measure the profile of multiple wheel paths simultaneously. The system can measure profile changes of less than 150 mils. Use of the system described herein will contribute to better roadways at lower costs.

  • Publication number: 20090092444
    Abstract: A concrete screed includes an engaging frame for readily engaging the mounting fixture of a skid loader or the like, with a pair of spaced parallel frame arms long enough to keep the skid loader off the concrete form, with a screed blade attached to the distal ends of the two frame arms. A pre-screed screeding blade having a V-shape is fixed to the screed blade for knocking down high spots in poured concrete. The side frame arms are free to pivot up and down at both ends. A pair of pulling arms, each pivotally connected to the screed blade at one end and to a side frame arm at the other, exert the actual pulling force that pulls the screed blade across the poured concrete. A pair of hydraulic vibrators fixed to the screed blade vibrates the screed blade to puddle and settle the concrete for leveling.

  • Publication number: 20090074511
    Abstract: A planetary grinding machine having a simple design with a minimal number of parts, which are all easily accessible for maintenance and repair is disclosed. The machine has a rotating planetary disk with rotating screeding disks attached. The planetary disk is driven by a shaft extending through a top housing cover plate, which supports a transmission driven by a motor. As the planetary disk rotates, a single belt engages a stationary gear on the cover plate and pulleys on screeding disk shafts to turn the screeding disks as the planetary disk is turned. The belts and pulleys for the drive mechanism are sandwiched between the planetary disk and the top cover to protect the mechanisms from dust and debris. The bearings are sealed to prevent dust and debris from entering and oil from escaping. The bearings, being on the inside of the planetary disk, keep oil from landing on the floor.

A concrete relief groove is located on the front face near the bottom surface to form a scraper edge. A ridge separates the thumb relief groove and the concrete groove. When the screed is used, the scraper edge and concrete relief groove draw up the concrete overburden from a concrete surface and deflect it away from the operator's hands.

  • Patent number: 7201537
    Abstract: A vibratory concrete screed includes a vibration isolation system that minimizes the transmission of vibrations to the operator under normal operating conditions, but becomes more rigid during screed control forces applied to the blade through the isolation system when the operator applies greater forces to the operator handle. The system includes low durometer elastomer vibration isolators isolating the operator handle from the vibration exciter and screed blade in a manner that limits vertical compressive movement of the isolators, yet permits substantially greater horizontal shear movement to effectively isolate the operator from vibration. The isolator mounting arrangement also includes retainers that engage the isolator to limit the amplitude of horizontal shear movement when the operator applies a greater control force to the operator handle.

  • Patent number: RE39834
    Abstract: A contouring device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by a pair of fluid cylinders. The fluid cylinders are controlled to raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of one of the fluid cylinders is based on a comparison of the measured position of a first end of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. The measurement of the position of the first end of the contouring assembly is achieved by a tracking device which tracks the position of a target positioned on the first end of the contouring assembly and which determines the three dimensional position of the target.
