Abstract
A concrete distribution system for pouring concrete floors over areas inaccessible to concrete trucks comprises a conduit assembly, leveling member, interconnecting cables and activating members. The conduit assembly includes a first rigid, moveable support which supports a first pipeline immediately above the area to be concreted. The pipeline has a plurality of openings through which the concrete is poured across the area. Control valves selectively open and close access to the openings so that concrete pours across the area. The first support is interconnected by cables with the leveling member. Activating members simultaneously move the conduit assembly and leveling member across the area to be concreted.
Claims15
An apparatus for distributing concrete over an area inaccessible by a concrete truck, comprising:
- a conduit assembly for supplying the concrete from the truck onto the area, said conduit assembly including a first end, second end, first support and first portion, said first support and said first portion extending from said first end to said second end of said conduit assembly, said first portion being coupled to said first support and having at least one opening therein for releasing the concrete onto the area;
- a leveling means spaced apart from said conduit assembly for leveling the concrete released onto the area from said first portion of said conduit assembly;
- an interconnecting means for coupling said conduit assembly and said leveling means together;
- and
- an activating means coupled to said conduit assembly for simultaneously moving said conduit assembly and said leveling means across the area.
An apparatus for distributing and screed leveling concrete over an area inaccessible by a concrete truck comprising:
- a conduit assembly for supplying the concrete onto the area, said conduit assembly including a first end, second end, first support, first pipeline portion and second pipeline portion;
- a plurality of cable members interconnecting said conduit assembly and the screed;
- an activating means coupled to said conduit assembly for simultaneously moving said conduit assembly and the screed across the area;
- said first support including a plurality of beams and feet, said beams fixedly secured together and extending substantially from said first conduit assembly end to said second conduit assembly end, said feet being securely coupled to said beams and being spaced apart between said first and said second conduit assembly ends for facilitating a slidable movement of said first support across the area;
- said first pipeline portion being rigid and coupled to said beams substantially from said first conduit assembly end to said second conduit assembly end and having a plurality of openings therein through which the concrete is distributed onto the area;
- and
- said second pipeline portion being flexible and having an end coupled to an end of said first pipeline portion and the other end of said second pipeline portion being adapted for coupling to the truck.
