This patent disclosure relates to road paving machines and, more particularly, to screed plates for a road paving machine.
The basic concept of the asphalt or concrete road paver system has remained relatively unchanged for many years. Screed plate assemblies and method for paving are found and utilized in various construction paving industrial settings, such as payment of highways, airports, streets and other sites requiring paving of constructional site beds and pads, requiring a paving mat. Paving materials, such as concrete or hot mix asphalt (HMA), is loaded in the front of the road paving tractor, typically in a hopper, and conveyed to the rear by a set of flight feeders (conveyor belts), where it is spread out to a desired width by a set of augers in the road paver, and then leveled and compacted by a screed plate. A critical feature of a road paver is the self-leveling, or free floating, screed plate which will determine the profile of the material being paved or placed on the road bed, the mat and its correct smoothness and thickness. The screed plate is the flat bottom portion of the screed assembly that flattens and compresses the material into the mat. The free floating screed plate slides across the material.
There has been a recognized in the road paving industry need for providing screed plates of differing textures to a road paving machine.
The conventional screed plate is constructed of a one piece metal alloy screed plate with a flat surface interacting with the paving materials. In the conventional technology used today, the paving machine provides an electrically heated screed assembly with heating elements attached to or adjacent to a screed plate. This conventional screed plate assembly provides for one screed plate underlying the paving machine. The road paver/finisher using the conventional screed plate has only one force vector applied on the material to the mat applied to the road surface. Only one force vector is applied on the material as it is paved on the road surface
The references described in the related art do not disclose features of the present invention and would not be as suitable for the required purpose of the present invention hereinafter described. Screed plate apparatuss are found in the related art, exemplified by U.S. Pat. No. 9,382,675 to Frelich et al. (“Frelich”) and U.S. Pat. No. 2,306,125 to Jackson (“Jackson”). Frelich discloses a paving machine having electrically powered vibrators to drive the screed assemblies, including one or screed plates configured to smooth the paving materials and a mechanism enabling further compaction of the paving material. There is no disclosure of a screed corrugation. Vertical vibration of a screed plate to achieve paving compaction is common in the industry, but there is no disclosure of horizontal or oscillating vibration in Frelich.
Jackson discloses a concrete paving machine having a screed provided with a means for generating, vibration, vibratory plates disposed on the front of the screed and a vertically fluted corrugated face portion having rearwardly curved lower edges. However, the bottom face of the screed plate is planar. The corrugated piece in Jackson is a tamper bar that operates separately from and in front of the screed plate. The apparatus in Jackson does not disclose or suggest corrugations or other texture on the bottom of the screed plate as set forth in the present invention. The corrugations of Jackson are limited to the vertical face portion of the screed, and are uniform throughout. There is no suggestion in these references for providing such corrugations on the bottom of the screed plate.
None of the references in the prior art contain every feature of the present invention, and none of these references in combination disclose, suggest or teach every feature of the present invention. The present invention is neither disclosed nor suggested by the prior art.
The foregoing and other objectives, advantages, aspects, and features of the present invention will be more fully understood and appreciated by those skilled in the art upon consideration of the detailed description of a preferred embodiment, presented below in conjunction with the accompanying drawings.
The present invention is a screed plate apparatus and method for homogeneously applying paving material to a road surface includes a road paver/finisher, a screed plate having a screed plate front side and an opposing screed plate back side, a screed plate top side and an opposing screed plate bottom side, a screed plate first side and an opposing screed plate second side, and a coupling element incorporated into the screed plate front side, as well as, at least two screed plate attaching means, located on the screed top side.
The road paver/finisher includes a material matting apparatus having a plate bottom and paving material, a power source, a heating element, and a structural/conductor plate. The material matting apparatus is an integrated component in the road paver/finisher, and contains paving material loaded into the material matting apparatus to pave surfaces and distributes that material from the road paver/finisher during paving operation, as the road paver/finisher paves or traverses in a paver travel direction.
The structural/conductor plate comprises a conductor top side and an opposing conductor bottom side, a conductor front side and an opposing conductor back side, a plurality of conductor plate fastening means, and at least two screed plate retaining means located on the opposing conductor bottom side. The plurality of conductor plate fastening means securely attach the structural/conductor plate directly to the plate bottom of the road paver/finisher. The coupling element enables a pressure connective coupling of the coupling element to the structural/conductor plate.
The power source generates heat to the heating element to preheat the screed plate so that the paving material does not stick to the screed plate. The heating element is located between the plate bottom and the conductor top side and, immediately against the conductor top side providing direct heat to the structural/conductor plate.
The at least two screed plate retaining means receive the appropriately matching and paired at least two screed plate attaching means, from the screed plate top side, and the conductor front side receives the appropriately matching and paired coupling element of the screed plate, whereby the structural/conductor plate heat-conductively attaches at the opposing conductor bottom side to the screed plate at the screed plate top side provides indirect heat to the screed plate.
The material matting apparatus applies paving material homogeneously as a paving mat to a road surface in a paver travel direction traversed by the road paver/finisher. The opposing screed plate bottom side further comprises a textured surface impacting the paving material as the screed plate compacts the paving material to the road surface. Differing forms of textured surface are provided in alternative embodiments, by the differing patterns or corrugations, allows the screed plate apparatus to manipulate the particular paving material applied to the road surface as the paving mat in a more homogeneous manner. In alternative embodiments to the screed plate apparatus the textured surface comprises a corrugated pattern orienting parallel to the paver travel direction, or orienting perpendicularly to the paver travel direction, and/or progressively flattening in a dampening corrugated pattern from the screed plate first side toward the opposing screed plate second side, or in a crisscross rhombic pattern, orienting acutely to the paver travel direction. In any of the embodiments, the plurality of corrugations comprise various forms, those being at least one of a repetitive wave form, a repetitive v-shaped pattern, a repetitive block shaped pattern, or a variably shaped wave pattern.
In another embodiment the material matting apparatus comprises a vibrating and oscillating mechanism, causing the material matting apparatus to forcibly operate horizontally and vertically upon the screed plate providing a homogeneously sorting on the paving material.
In another embodiment of the present invention, the power source causes the heating element to directly heat the screed plate.
In advantage of the present invention is that differing types of paving material may be employed to allow for differing products to be used to create a paving mat on the road surface. Another advantage is that the screed plate may be made of different materials.
The variable wave design allows the material matting apparatus to compact the paving material into a paving mat. The screed plate apparatus allows, therefore, the paving material to be compartmentalized under the screed plate by the addition of variable force vectors employed on the paving material at varying angles, producing a more homogeneous paving mat. The screed plate apparatus is driven in one alterative by the vibrating or oscillating mechanism which provides the varying force vectors to the paving material.
The variable corrugated or wave screed plate can be used for the laying of pavement, using differing paving materials, including bituminous plant mix concrete, Portland cement concrete or other surface or subsurface materials.

The problem of having only once force vector, or one direction of force applied by the material matting apparatus 122 in
The screed plate apparatus 100 of the present invention is driven in one alterative by the vibrating or oscillating mechanism 129 contained in the material matting apparatus 122, integral parts of the road paver/finisher 120, commonly used and recognized in the industry, and depicted in
The screed plate apparatus 100 of the present invention allows for a variable corrugated or wave screed plate 101 opposing screed plate bottom side 105 with variable shapes or corrugations, corrugated pattern 131, and wave amplitudes and frequency, as shown in
The variable corrugated or wave screed plate 101 can be used in the road construction industry for the laying of pavement, using differing paving materials 110, including bituminous plant mix concrete, Portland cement concrete or other surface or subsurface materials. The flexibility in sue therefore will improve the texture and density of the paving material 110 directly behind the screed plate and make further compaction of the paving material where needed easier to achieve. The present invention may be used in any paving application where paving material 110 is being laid into the paving mat 153, from particulate materials, as well, for road surface 123, including for highways, airpost runways, roads and parking lot pavings.
The force applied by the road paver/finisher 120 may be characterized in terms of variable force vectors. The advantage of the present invention is that these variable force vectors will organize and apply added force to the paving material 110, improving paving mat 153 texture and density, as desired. One benefit of this advantage is to allow an increased over-all density to the paving mat 153, and increased density in road surface 123, combating ruts and irregularities, or, alternatively, providing more consistent densities when desired. A more stable road surface 123 is created thereby, with the additional compaction and a more even texture to the paving mat 153 when desired by a denser and more organized paving material 110 or aggregate.
