Apparatus for forming concrete barriers
First Claim
1. A system for continuously forming a concrete structure which extends in a substantially horizontal direction and has a predetermined cross-sectional configuration, the system comprising:
- a frame;
first form means, coupled to said frame, for supporting a portion of one side of a concrete structure being formed;
second form means for supporting at least a portion of an opposite side of the concrete structure and for forming a pattern in the outside surface of the opposite side comprising concave or convex portions which extend other than just in the substantially horizontal direction, said concave or convex portions forming the reverse image of a pattern to be provided on the opposite side of the concrete structure, said second form means coacting with said first form means so as to enclose an area having a cross-sectional configuration corresponding to the predetermined cross-sectional configuration of the concrete structure, said second form means including a rigid wall to structurally support said pattern, wherein said second form means is fixed with respect to a surface on which the concrete structure is formed;
drive means coupled to said frame for causing said frame to move in said substantially horizontal direction; and
support means coupled to said frame so that said drive means causes said support means to move in said substantially horizontal direction for supporting successive portions of said second form means relative to said first form means as said drive means moves in the horizontal direction so as to permit said second form means to coact with said first form means so as to enclose said area, said support means not contacting the concrete structure and only contacting a portion of said rigid wall to reduce friction therebetween.

Abstract
A system for continuously forming a concrete structure that extends in a generally horizontal direction and has a predetermined cross-sectional configuration is provided. The system includes a frame, a first form, and a second form. The first and second forms are coupled to the frame and support at least a portion of the sides of the concrete structure being formed. The second form forms a pattern in one of the outside surfaces of the concrete. The first form may also form a pattern. The pattern includes concave and convex portions that extend other than just in the horizontal direction. The second form coacts with the first form to enclose an area having a cross-sectional configuration corresponding to the predetermined cross-sectional configuration of the concrete structure. The frame includes a side arm assembly that slidingly engages the outside of one or both of the forms.

16. A system for continuously forming a concrete structure which extends in a substantially horizontal direction and has a predetermined cross-sectional configuration, the system comprising:
-
a frame; first form means for supporting at least a portion of a first side of the concrete structure and for forming a pattern in the outside surface of the first side comprising concave or convex portions which extend other than in a horizontal direction, said concave or convex portions forming a reverse image of a pattern to be provided on the first side of the concrete structure, said first form means including a rigid wall to support said pattern; second form means for supporting at least a portion of an opposite side of the concrete structure and for forming a pattern on the inside of the opposite side comprising concave or convex portions which extend other than just in a horizontal direction, said concave or convex portions forming a reverse image of a pattern to be provided on the opposite side of the concrete structure, the second form means coacting with said first form means so as to enclose an area having a cross-sectional configuration corresponding to the predetermined cross-sectional configuration of the concrete structure, said second form means including a rigid wall to support pattern; drive means coupled to said frame for causing said frame to move in the substantially horizontal direction; and support means coupled to said frame for supporting said first and second form means relative to one another as said drive means moves in said substantially horizontal direction so as to permit said first and second form means to coact with one another so as to enclose said area, said support means contacting only a portion of said rigid wall of said first and second form means. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A device for slip forming a concrete structure along a substantially horizontal path, the device coatting with first and second forms which extend along the path to support, and define the configuration of both sides of, the structure, the first and second forms each having an inner surface which engages a side of the structure, the first and second forms including a pattern comprising concave or convex portions which extend other than parallel to the path, the first and second forms including rigid walls to support the pattern, the device comprising:
-
a frame; drive means coupled to said frame for moving said frame along the substantially horizontal path; and support means coupled to said frame for supporting said first and second forms relative to one another as said drive means moves said frame along said path so as to cause said first and second forms to coact with one another and enclose an area that defines the cross-sectional shape of a concrete structure to be formed by said device, wherein said support means comprises slide means for slidingly engaging and supporting an outer surface of said first and second forms as said slide means is caused to move along said path by said drive means, wherein said slide means comprises at least one rail which extends parallel to the path to slidingly engage the outer surface of the form;
a plurality of supports which extend transversely to, and are attached to, said at least one rail; and
a support assembly attached to said plurality of supports for coupling said plurality of supports with said frame and for adjusting the position of said plurality of supports relative to said frame.
