Abstract
A method is provided for converting a four-track slip form paver into an improved three-track slip form paver for applying a continuous slab of concrete onto a road surface and against a vertical abutment adjacent the road surface.
Claims12
A slip form paving apparatus for applying a concrete slab onto a substantially horizontal surface and against a substantially vertical surface at one side of the horizontal surface, comprising:
- a rigid, rectangular frame having a front end, rear end and first and second sides;
- paving means secured to the frame extending from the first side of the frame to a point outwardly of the second side of the frame, the side of the paving means extending beyond the second side of the frame being open;
- a slip form on the side of the paving means at said first side of the frame;
- first mobile ground support means secured to and supporting the frame at said first side;
- and
- second mobile ground support means secured to and supporting the second side of the frame, said second mobile ground support means disposed ahead of the paving means;
- said ground support means operable for moving the open end of the second side of the paving means alongside the vertical surface, whereby the concrete laid by the apparatus will abut the vertical surface.
A method of converting a four-track slip form paver to a three-track slip form paver capable of paving against a vertical surface at one side of the path of travel of the paver, the four track paver having a rectangular frame with a front end a rear end and two sides and a mobile ground support structure at each corner, a hopper extending across the frame for receiving and spreading concrete across the surface being paved, and a profile pan behind the hopper extending across the frame for shaping the concrete into slab, the pan having a slip form on each side thereof, comprising the steps of:
- removing one of the mobile ground support structures at a rear corner of the frame;
- removing the slip form from the side of the profile pan at the side of the frame associated with the removed mobile ground support;
- and
- extending the hopper and profile pan outwardly from the side of the frame associated with the removed mobile ground support structure beyond the ground support structure associated with said side.
