摘要： A soft landing control system (10) for a screeding device (12) is operable to automatically lower a vibrating member (24) of a screed head assembly (14) into engagement with a concrete surface at a time and place where the vibrating member is not positioned over an overlap area of already screeded concrete. The vibrating member is automatically lowered onto newly placed concrete at or near the junction or cold-joint between the already screeded concrete and the area of newly placed concrete, so as to avoid depressions in the already placed concrete. Optionally, the soft landing control system may include a timing device and may lower the vibrating member after a period of time following an activating event. Optionally, the control system may detect when the vibrating device is positioned at or near the newly placed concrete and may lower the vibrating member in response to such detection.

摘要： Vibration energy introduced into plastic concrete structures, such as concrete slabs, decks and similar or related concrete structures, at or near the natural resonant frequency of the liquid concrete mass (M), expedites the consolidation and setting of the concrete. A vibrating apparatus (3) imparts controlled vibrations either onto the surface or beneath the surface of the concrete mass (M) in sequential stages, the frequency of vibrations generally increasing with each subsequent stage, corresponding to the increase in the natural resonant frequency of the progressively-narrowing liquid concrete (M2) at the top of the structure. The relatively more consolidated and more dry concrete (M1) (typically near the bottom of the slab) is substantially unaffected by the non-resonant frequencies. In one modification, sensors (5) determine the resonant frequency of the liquid concrete mass (M2) during each pass of the vibrator apparatus (3), and the frequency of the vibrating member (82) is automatically adjusted, accordingly. The number of stages, the amplitude of the vibrations, the physical orientation of the vibration-producing apparatus (3), the time duration in each stage, is variable depending upon the physical characteristics of the concrete mass (M2).

摘要： An apparatus (10) for screeding and smoothing an uncured concrete surface includes a concrete surface working member (20), such as a vibrating beam or member, and a grade setting device (18) adjustably mounted to the vibrating beam (20). The apparatus may include a wheeled support (217) which at least partially supports the vibrating beam (20) and/or the grade setting device (18). The wheels (217b) of the wheeled support (217) may be powered or driven to assist an operator in moving the apparatus over and through the uncured concrete. The grade setting device (18) is vertically adjustable to set or indicate the desired grade of the concrete surface as the screeding apparatus is moved over and through the uncured concrete. The grade setting device (18) may be adjusted by a laser plane responsive control system.

摘要： A device for planation of fresh concrete surface by means of surface vibration and comprising a planation means (11), equipped with a vibrator (14) and an attachment (15) for a holder (17) rotatably mounted in the vertical plane. The purpose is to provide a device which is suitable for planation of a fresh concrete surface without using screeding paths or levelling means and without leaving any marks on the way to and from the place where the planation is to take place. Furthermore it should be possible to level very small as well as large volumes of concrete over a larger or smaller surface. These objects have been attained by the fact that the vibrator regarding the vibration effect is adjustable, and that at the free end of the holder a regulating device is applied for adjusting of vibration effect.

摘要： A rotating cylinder cement screeding system (10) having a drive assembly (20) and handle (26) at one end for powering and controlling the screeding system. The rotating cylinder (12) is made of tubular screed rollers of varying lengths allowing a user to customize the length of the system to match a specific cement pour (18) . Further, each tubular screed roller is supplied with a male and female end for interlocking with each other and for receiving a variety of add on attachments such as an end pull, a slab drop down member, a footing member guide, a center anchor member and a counter rotation member. The rotating cylinder may also be equipped with a constant velocity type U- joint to allow the rotating cylinder to flex and thus, allow for pours with crowns or valleys, as needed by the cement installer.

摘要： A portable vibratory screed machine is configured with a vibration restraint operable to reduce undesirable vibration of the engine and to extend the life of the engine. The portable vibratory screed machine includes a machine frame (35) having a reference structure. The machine further includes an engine (30) mounted on the reference structure via a mount that surrounds a drive shaft that is driven by the engine's output. A vibratory assembly remotely located from the engine is powered by the engine to vibrate a screed plate. The vibration restraint (20) directly couples the engine housing to the reference structure at a location that is spaced apart from the mount.
