Abstract: A system and method for elevating a construction implement relative to a surface under construction includes erecting a support post having a generally hollow cavity on the surface under construction, such as a dam. A quantity of granular material is then dumped into the hollow cavity of the support post. The support post and, specifically, the construction implement, is then jacked to a desired height relative to the surface. A portion of the granular material is then permitted to disperse through and beneath the support post thereby creating a higher support structure on which the support post may then rest. This process may be repeated as the construction progresses and the surface is gradually raised.

The conveyor truss module also includes a plurality of lacing struts coupled to the single-pin top chord joint and the corners of the base assembly.

Abstract: A chord member for facilitating the assembly and disassembly of a concrete conveyor system including a top flange defining a first plane, a pair of depending lips positioned at either end of the top flange, a bottom flange defining a second plane parallel to the first plane and a middle flange defining a third plane perpendicular to the first plane. A clevis is coupled to the top flange or the bottom flange so that a truss of the conveyor system can be attached to the clevis.

Abstract: Apparatus for raising a conveyor above the surface of a poured concrete structure as the structure is formed includes a post moveable in a vertical direction that supports a conveyor on top of the post. A horizontal support tube is connected to the post, as well as a collar. A jack engages the support and raises the post and collar. A hydraulic means then places a base around the post below the collar so that when the jack is lowered, the conveyor, post and collar are supported by the newly placed base, thereby raising the conveyor relative to the surface of the structure.

Abstract: A self-propelled vehicle mounting a cantilevered conveyor truss for concrete and the like. An improved force balancing frame enables the vehicle to remain stable even though the truss conveyor is extended to maximum length and elevated to a high angle. Improved geometry enables the truss conveyor to be pivoted at a point above a cab mounted on a turntable of the vehicle and forward of the axis of rotation of the turntable, thereby facilitating the deposit of concrete on the conveyor. Polyethylene pads control the motion of the truss conveyors, especially when the truss conveyor is elevated to a high angle. A unique drive assembly enables a mid-section and fly section of the truss conveyor to be moved simultaneously with respect to a base section of truss conveyor such that the fly section moves at twice the rate of the mid-section.

Abstract: An apparatus for delivering concrete to two spaced deposition points having a funnel-shaped hopper with a pair of outlets in the bottom which deposit concrete on conveyors. An inclined chute feeds concrete to the inner conical wall of the hopper as the chute rotates to minimize segregation of the concrete. Each outlet has a gate to control flow of the concrete to the conveyor beneath.To divert concrete from the hopper a side discharge chute is pivotally mounted in the conical wall of the hopper and can be tilted to receive concrete discharged from the inclined chute.

Abstract: The disclosure describes a method and apparatus for continuous mixing, transporting and placing of large quantities of concrete in which aggregate transported on a belt conveyor is mixed with metered quantities of cement and water adjacent a place of pouring. Alternatively, mixed concrete is transported to a place of pouring protected from the elements on a belt conveyor covered by a tunnel that confines cooled air.

Abstract: A concrete finishing machine having a movable framework mounted transversely over a paved area and defining an axis. A carriage is movably attached to the framework and has means for moving the carriage along the length of the framework. The carriage carries at least one rotating auger unit having leading and trailing portions mounted on one shaft and a finishing member. The auger unit has a leading portion having a helically arranged blade with an outer edge that is positioned in a fixed, spaced relationship with a desired grade. The trailing portion has a helically arranged blade with a band attached thereto to spread forward the excess concrete left by the leading portion and to finish the concrete at the desired grade. Plunging concrete vibrators are placed adjacent the auger unit leading portions.

Abstract: An improved dowel or tying bar and joint construction for transferring stresses across a joint between concrete slabs or structures and accommodating for shrinkage and expansion of concrete. The bar has a resilient facing attached to at least one side of the bar so that the concrete slab or structure can move in relationship to the bar in a direction substantially perpendicular to the resilient facing. The bar is arranged across the joint in a direction substantially perpendicular to the axis defined by the joint.

Abstract: An over-the-road vehicle having a pivotally-mounted telescoping boom which moves in and out, up and down, and from side to side. An extensible concrete conveyor belt is mounted on the boom for movement with the boom for conveying and placing concrete within the reach of the boom. The vehicle is equipped with stabilizing outriggers which are pivotally mounted on the vehicle and can be folded back in nesting relation to minimize the width of the vehicle during transit. The vehicle also carries a separate belt conveyor for feeding concrete to the extensible conveyor, the discharge end of said separate conveyor being mounted on arms which fold down to reduce the overall height of the vehicle during transit.

Abstract: A load sensor for a concrete conveyor having a tremie which sounds a signal and releases the tremie in case the tremie becomes overloaded. The device has a U-shaped deflection yoke between the tremie and the conveyor which deflects under the weight of the tremie to close switches and actuate the appropriate safety device. All parts are protected from concrete to insure proper functioning.

Preferably, the inner arm section is pivotally mounted on the base for rotation about a vertical axis and the outer arm section is pivotally mounted on the inner arm section for rotation and angular elevation. The device is joined with pins for assembly and disassembly for easy transport.

Abstract: Apparatus for conveying concrete mix to distant, elevated points includes a two-segment discharge conveyor with its outer segment suspended from a movable trolley that is mounted on the boom of a cantilever crane. The segments are pivotally joined and the discharge point of the outer segment may be positioned by swinging the boom and first conveyor and driving the trolley along the boom.

Abstract: An auger hopper for transferring cementious material or the like from a supply source such as a cement truck or dump truck to a conveyor belt. A hopper is provided together with a frame for permitting the hopper to straddle and attach to the conveyor. An auger is floatably mounted for rotation within and near the bottom of the hopper. The hopper and conveyor are movably mounted on wheels. Means for mounting at least one of the wheels is provided by which the attitude of at least one wheel mounting means may be varied in relation to the hopper and conveyor. The auger operates to drive cementious materials from the ends of the hopper toward the center and then to discharge the cementious material through a discharge opening at the bottom and onto the conveyor belt without plugging the hopper.

Abstract: In a multiple, variable length conveyor system having at least two conveyor frames, one conveyor frame movable parallel to the other frame, a single, slack-free conveyor belt is positioned in combination with both frames and passes in a continuous loop forward from the back of the top conveyor to the front thereof, back from the front of the top conveyor to the back of bottom conveyor, forward from the back of the bottom conveyor to the front thereof and back over the front of the top conveyor to the back thereof to complete the loop. This single belt system permits relative movement between the conveyor frames from a collapsed state to an extended state and obviates the need for separate conveyor belts for each conveyor frame. This system is particularly applicable to multiple, variable length conveyors for conveying concrete such as multiple conveyors positioned above the extendible boom of a crane-type wheeled vehicle.

Abstract: Conveying means is mounted on an extensible boom of a wheeled vehicle in such manner that one end of the conveyor system is adapted to receive materials such as concrete or the like from a delivery truck and the other end is adapted to discharge the materials, as through a tremie, into a wall form or the like. The arrangement is such that the boom of the wheeled vehicle can be extended and retracted, inclined and swung from side to side during a continuous materials delivery operation so that the tremie can follow the outline of the wall form for evenly distributing the materials therein. The extension, elevation and wing of the boom can be effected by the operator without interrupting the flow of materials, and the form filling job can therefore be completed in a minimum of time.
