| A method and apparatus for screeding post tensioned concrete slabs includes providing a screeding device (10) having a wheeled support (12) having a frame portion (30) and spaced apart wheels (34) rotatably mounted to the frame portion. The screeding device has a screed head (14) mounted to the wheeled support. The screed head includes a vibrating member (18) and a grade setting device (16) adjustably mounted to the vibrating member. The vibrating member is at least partially supportable on the uncured concrete surface, and the grade setting device is adjustable relative to the vibrating member to strike off excess uncured concrete in front of the vibrating member to establish the desired grade or level of the uncured concrete. The screed head may be pivotable relative to the wheeled support about a longitudinal pivot axis (20a) extending along the screeding device and in the direction of travel of the screeding device. | ||||||

| 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.

| 183 | METHOD AND APPARATUS FOR ELECTRICALLY HEATING A SCREED ASSEMBLY IN A PAVING MACHINE | EP01900326.8 | 2001-01-04 | EP1246971B1 | 2005-06-22 | SWEARINGEN, David |
| A paving machine (20) employs an electrically heated screed assembly (30) to uniformly heat a screed plate (46) of the machine. Uniform heating is achieved by inserting a thermally conductive plate (62) between electrical heating elements (60) and the screed plate (46). An insulation layer (68) may be provided above the heating elements (60) to direct the heat downward into the thermally conductive plate (62). The heat spreads relatively uniformly throughout the termally conductive plate (62), thereby uniformly heating the screed plate (46). A clamping mechanism (74) is also provided that, when tightened, provides a compressive force, thereby holding the assembly in place. When released, the pressure is alleviated, thus permitting a heating element to be removed for repair or replacement without the need to remove the screed plate. | ||||||

| An applicator (10) for applying seamless flooring material to a subfloor (11) including a chassis (12) steerably mounted on wheels (14, 16, 18). A dispensing hopper (28) on a frame (30) is towed behind the chassis (12) from a shaft (74, 76) on a steering column (72) and enabled to move in three dimensions independent of the chassis (12). The hopper (28) is supported by hopper wheels (296, 298) with the flooring material dispensed out of the hopper (28). The height of each side of the hopper (28) is independently adjustable on each side by screw-threaded rods (302, 304) and is not disrupted by lifting the hopper (28) out of operation. | ||||||

| A rotary pivot arm positioning assembly for a paving, texturing, or curing machine allows the machine to automatically transition from an operational orientation to a transport orientation without manual repositioning or disconnection of its components. The assembly includes a pivot arm coupled to both the front and aft ends of an end frame by a helical actuator, slew gear drive or other rotary actuator. The rotary actuator articulates each pivot arm, as well as the adjustable leg and steerable crawler connected to the pivot arm, through at least a 90-degree range. The end frame may be fixed to the left or right end of the machine. The assembly may additionally include a second helical actuator, slew gear drive or rotary actuator connecting each steerable crawler to the adjustable leg and configured to rotate the steerable crawler through a full 360 degrees. | ||||||

| A compaction roller assembly (10) includes a lobed non-circular impact roller (12) operably mounted on a draw frame (14) and a grader (16) operably mounted behind the impact roller (12) to level the corrugated ground surface produced by the impact roller. The grader (16) includes a pair of diverging frame members (22) with a pair of blades (54) mounted thereon and depending therefrom with the lower edges of the blades lying within a generally horizontal plane. A plurality of teeth (60) may be mounted to the frame members (22) to scarify the soil, each tooth (60) being removably connected to the frame members to permit ease of conversion between a grader blade and a scarifier. Each tooth (60) is a generally flat plate, the plates oriented parallel to one another and parallel to the line of travel of the grader (16). Each tooth plate forward edge (68) includes a concave arc-shaped lower portion extending from the lower end of the tooth to a point proximal the lower edge of the blade. Removable support skids (86) are provided to the frame member for supporting the grader in fine particulate soil. | ||||||

| A concrete finishing machine having a rotatable trowel blade assembly (11) and a mechanism (27, 29, 33) for controllably adjusting the pitch of the trowel blades (15) relative to a wet concrete surface (19) on which the blades rest. Manual pivoting of a control lever (25) controllably adjusts the trowel blade pitch and, in doing so, automatically increases or decreases the amount of blade surface contacting the concrete surface (19), and correspondingly lowers or raises the machine relative to the surface (19). The contacting blade surface supports the machine's entire weight. A special counterbalancing apparatus that includes, for example, a compressed coil spring (51), biases the control lever (25) so as to compensate for the machine's weight and permits an operator to adjust the blade pitch with substantially less force than otherwise would be required. | ||||||
