  • Patent number: 9995008
    Abstract: A system for controlling a vibratory effort on an asphalt mat includes a screed having a screed frame, a screed plate, and a vibratory mechanism. The screed plate and the vibratory mechanism are mounted on the screed frame and the vibratory mechanism is configured to vibrate the screed frame. The system further includes a sensor mounted on the screed frame, and configured to generate signals indicative of a vibrating parameter of the screed frame. The system further includes a controller in communication with the sensor and the vibratory mechanism. The controller is configured to receive the vibrating parameter, and further compare the vibrating parameter to a threshold parameter. The threshold parameter is the decoupling point of the screed frame. The controller is further configured to control the vibratory mechanism to reduce the vibrating parameter when the vibrating parameter exceeds the threshold parameter.

    Abstract: The apparatus and method comprise a concrete float with a vibratory additive broadcaster assembly attached therewith. The broadcaster assembly is suspended above the plane of the finishing tool with a vibratory source attached. The broadcaster assembly is filled with an additive and the apparatus is placed on a wet, concrete surface that is to be treated and finished, by a user. Actuation of a power switch by the user activates the vibratory source resulting in the substantial broadcast of additive on to the concrete surface at the desired location(s) on the slab as determined by the user. Vibration damper devices are utilized to minimize the vibrations experienced by the float. The additive is integrated into the concrete or other wet surface by passage of the float over the surface being treated.

  • Patent number: 7465121
    Abstract: A hand trowel for vibrating concrete in order to smooth the concrete. The trowel has a blade, a handle mounted on the blade, and electrical components including a motor inside the handle. When the switch is turned on, the motor causes the handle to vibrate, which in turn transmits vibrations to the blade and to the concrete surfaces that come in contact with the blade.

  • Patent number: 7407339
    Abstract: A wheeled strike-off apparatus is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support and a plow assembly. The plow assembly may be adjustably mounted to a front frame portion and may be vertically adjustable relative to the frame portion. The plow assembly may include a plow member for engaging and establishing the desired grade and/or may include a vibrating member for vibrating and smoothing the concrete after the plow member establishes the desired grade. The apparatus may include a user input that is adjustable by an operator to adjust a down pressure of the plow assembly at the concrete when the wheeled support is moved in a rearward direction.

  • Publication number: 20080131205
    Abstract: A wheeled screeding apparatus includes a vibrating member adjustably mounted at an end of a frame portion of a wheeled support, with the vibrating member at least partially supporting the end of the frame portion. The vibrating member is generally vertically adjustable relative to the frame portion to adjust a level of the vibrating member relative to the wheeled support. A level control is operable to automatically adjust the vibrating member relative to the frame portion in response to an output of a level sensor, with the level control automatically adjusting the vibrating member relative to the frame portion to substantially maintain the frame portion at a desired orientation relative to horizontal as the screeding device is moved over and through the uncured concrete in a screeding direction.

  • Publication number: 20080050177
    Abstract: The orbital vibrating hand trowel has a body with first and second opposite ends and a handle between the ends for grasping. The body houses a motor and power source. An eccentric mass is connected to the motor. An adapter body is connected to a float body. The adapter body has an aperture for housing the eccentric mass such that rotation of the eccentric mass within the aperture of the adaptor body moves and vibrates the adaptor body and attached float body in an orbital path along a horizontal plane with respect to the float body for finishing a surface.

  • Patent number: 7316523
    Abstract: Methods and apparatus for screeding freshly placed concrete in which the acoustic impedance of the treating equipment is made substantially equal to the acoustic impedance of the concrete slab. Portions of the screed contacting the plastic concrete are matched to an acoustic impedance approximating the acoustic impedance of plastic concrete, promoting the energy transferred to the concrete. The acoustic matching material is fabricated from a material that has an acoustic impedance within 67% to 150% of the acoustic impedance of the concrete being finished. The acoustic matching material has an abrasion resistance of no greater than 150 measured using ASTM Method G-65 where steel is given a rating of 100. The preferred matching material comprises ultra-high molecular weight polyethylene (UHMWPE) plastic.

  • Patent number: 7316524
    Abstract: A tamping device for tamping of asphalt or stone includes a motor being coupled to a drive shaft. The motor rotates the drive shaft when the motor is actuated. A sleeve is coupled to the motor. The drive shaft extends through the sleeve. A transmission housing is coupled to the sleeve opposite the motor. The drive shaft extends into the transmission housing. A foot assembly is rotatably coupled to the transmission housing. An angle of the transmission housing and the sleeve is adjustable with respect to the foot assembly. The foot assembly vibrates when the motor is actuated to tamp the asphalt or the stone and the foot assembly is drawn across the asphalt or the stone.

  • Publication number: 20070292208
    Abstract: A portable vibratory screed includes a blade that is connected to a handle constructed to be manipulated by an operator. Nodes of minimum vibrational amplitude are formed at specific locations along the length of the blade when the exciter is driven at a rated operating speed. A site level and/or the handle is attached to the blade at or in the vicinity of one or more of these nodes, therefore, is relatively isolated from induced vibrations.

  • 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.
