Definitions

  • the present invention relates to an improved screeding apparatus and novel components particularly suited for use with screeding apparatus.
  • Screeding machines known in the art are used to level large areas of poured, uncured concrete, such as roads or large floors found in warehouses or department stores. These screeding machines are typically very large and heavy. Due to their weight, they are typically restricted to use on the ground floor of most buildings.
  • screeding machines are supported by wheels which run adjacent to the area being screeded. With such designs, screeding machines can generally work along a predetermined path and are not particularly suited for screeding smaller areas off the predetermined path.
  • Other screeding machines have been designed to be driven through poured concrete while supporting a screed behind the wheels in order to displace excess concrete and to level the concrete surface.
  • poured concrete is quite often strengthened, for example, by reinforcement bars, commonly known as rebar.
  • the strength of the rebar limits the weight of a screeding machine since the rebar could be damaged by excessive weight.
  • One aspect of the present invention comprises a novel screeding apparatus which is designed to be driven through poured, uncured concrete.
  • a screeding apparatus is provided with novel wheels which can be moved through concrete after screeding and without requiring the re-screeding of the areas through which the wheels have passed.
  • a screeding apparatus is provided with at least one open frame wheel and at least one vibrator for vibrating at least one wheel as the wheel passes through uncured concrete.
  • the vibrating mechanism is adjustable in order to increase the force and/or frequency of the vibration applied to the wheel.
  • the term "open frame" is used to indicate that concrete can flow substantially freely around or through the wheel.
  • uncured concrete can flow at least partially in a direction perpendicular to the path of travel of the screeding machine.
  • a screeding apparatus 10 comprising a frame 20 which is movably supported by four wheel assemblies 50, only two of which are clearly shown in Fig. 1.
  • the illustrated wheels are designed to pass directly through uncured concrete either before or after that concrete section has been screeded.
  • the illustrated wheel assemblies 50 are attached to the frame 20 by a pivotal, four-bar linkage 60.
  • Those skilled in the art will appreciate that as screeding apparatus 10 is propelled through uncured concrete, the wheels will ride up and down over various objects, e.g., reinforcement bars, stones, etc. Therefore, it is desirable to provide some degree of resilience between the wheel assemblies 50 and the frame 20 with a four-bar linkage or some other controlled pivotal attachment.
  • the preferred illustrated wheel assemblies comprise wheel segments 52 connected to an axle 54 which is connected to a hydraulic drive 56.
  • Each wheel assembly is also advantageously provided with a vibration assembly 58 which vibrates the wheel segments 52 as they pass through the uncured concrete.
  • the vibration caused by vibration assembly 58 is preferably adjustable with suitable controls (not shown). In this manner, the frequency, force and amplitude of the vibration imparted to the wheel assembly can be adjusted in order to provide sufficient vibration such that wheel assemblies passing through screeded concrete will urge the concrete to a sufficiently smooth finish so that further screeding is unnecessary. It is also desirable to avoid too much vibration in some situations. For example, those skilled in the concrete art will appreciate that concrete can be vibrated too much, the stones will settle down to the bottom of the concrete and lose part of their effectiveness.
  • Fig. 1 illustrates a pair of detectors 80 for the laser leveling system.
  • the detectors are linked to a pneumatically operated vertical control system comprising a hydraulic piston 90 and a linear bearing assembly 110 which cooperate to provide vertical adjustment to the screed 120 as the screeding apparatus 10 is propelled through the uncured concrete.
  • Linear bearing assembly 110 advantageously bears some of the load of the vertical support bar 115 while permitting the hydraulic piston 90 to provide the needed vertical adjustments.
  • the angle of the screed 120 is also advantageously adjustable utilizing hydraulic controls 130 which are pivotally connected to vertical support bars 115.
  • Suitable controls are provided to operate and coordinate each of the various operations of screeding apparatus 10.
  • one or more potentiometers can be used to control the speed and vibration of the screed as it passes through the uncured concrete.
  • these controls are not explained in greater detail herein.
  • a screeding apparatus 200 is designed to be self-propelled through uncured concrete in the direction indicated by arrow A.
  • a plow blade 205 which is height adjustable in order to remove large quantities of excess concrete.
  • a set of wheel assemblies 220 which are vibrated by vibration mechanisms 225.
  • Additional concrete vibrators 230 are provided to impart desired vibrations to the uncured concrete.
  • a rotatable auger 240 which is preferable designed to direct finer quantities of excess concrete either in a single desired direction or out to both sides of the screeding apparatus 200.
  • a laser leveling apparatus which can be of the type described in reference to Figure 1. While a laser leveling system is preferred, it is within the scope of the present invention to use other leveling systems such as sonar, string line guide, mathematical adjustment and manual adjustment.
  • Suitable controls are provided to operate and coordinate each of the various operations of screeding apparatus 200 including, for example, the speed of rotation of the wheel assemblies, the direction of the wheel assemblies, the frequency and force applied by the different vibrating mechanisms, the heights and pitches of the plow augers and levelers. These controls are most preferably remote controls.
  • Fig. 13 shows greater detail of a wheel assembly 50 wherein wheel segments 52 are connected to axle 54.
  • the wheel assembly comprises four wheel segments.
  • Each wheel segment comprises a spoke portion 51 and a support portion 53 comprising an arcuate surface.
  • Each of the illustrated support portions 53 of this illustrated embodiment preferably pass through an angle of about 70 - 130° degrees.
  • adjacent, spaced wheel segments are positioned with circumferentially overlapping portions in the same manner as wheel assemblies 220 illustrated in Fig. 2.
  • wheels similar to wheel assemblies 50 may be utilized using different numbers of wheel segments which pass through greater or smaller circumferential arcs.
  • the present invention offers a number of different designs for supporting a screeding apparatus. From the present description, those skilled in the art will appreciate that a particular support can be selected for a particular application. Elevated decks and subgrades can include sand, gravel, metal decks, wood decks, plastic barriers and different reinforcement materials including rebar, wire mesh and/or fiber mesh. Therefore, the particular support utilized will take the particular decking and/or subgrade into account.
  • Figure 4 illustrates an alternative drive mechanism wherein a plurality of radially-offset spherical supports 63 are supported in space relation from a central hub by spoke portion 61. Each of the spoke portion 61 are connected to a cylindrical axle 64. In order to facilitate repair and/or replacement of the spherical support 63, in the event of damage or routine maintenance and replacement, the axle 64 is also formed in a plurality of segments which can easily be removed and replaced.
  • Figure 5 illustrates an alternative arrangement comprising a plurality of radially-offset generally arcuate support 73 positioned at the ends of spoke portion 71 each of which are connected to a axle segment 74.
  • a plurality of closed loop supports 83 are connected via spoke portions 81 to axle segments 84.
  • Figure 7 illustrates an alternative embodiment wherein closed segments 93 are attached to axle segments.
  • the generally arcuate, closed supports 93 are preferably designed to overlap when viewed along the longitudinal axis of axle portions 94.
  • the support sections 93 are most preferably formed with rounded outer faces in order to provide a smooth motion for the screeding device through uncured concrete.
  • the supports 93 can either be solid or hollow.
  • Figures 8 and 9 illustrate further embodiments which comprise disks 103 mounted on axles 104 and irregular disks 113 mounted on axle 114, respectively.
  • the embodiment of Fig. 10 comprises an open wire structure 122 supported by rounded disks 123 and mounted on a central axle 124.
  • the spacing of the wire in this embodiment is most preferably designed to permit the wire structure to be rotated out of the uncured concrete while leaving the concrete sufficiently smooth to avoid the need for additional screeding.
  • Figures 11 and 12 illustrate further embodiments of supports of the present invention wherein a plurality of spaced wheels are mounted on axles by spaced spokes or supports.
  • Another aspect of the present invention comprises method of leveling uncured concrete comprising the steps of providing a screeding apparatus comprising a plurality of supports which pass through the uncured concrete and a leveling mechanism; passing said screeding apparatus through said uncured concrete such that at least one of said supports passes through a section of concrete which has already been leveled by said leveling mechanism.
