| 20090146043 | MODULAR FORM FOR CASTING CONCRETE HIGHWAY BARRIERS - A modular form has stackable upper and lower forms for casting concrete highway barriers. The lower form has opposing lower faces spaced apart to define a lower mold cavity, ties removably extending through the lower faces and lower mold cavity, and attachment angles extending along the top edges of the lower faces. The upper form has opposing upper faces spaced apart to define an upper mold cavity, ties removably extending through the upper faces and upper mold cavity, and attachment angles extending along the bottom edges of the upper faces. After the upper form has been stacked atop the lower form, fasteners are employed to removably secure the attachment angles of the lower form to those of the upper form. Thus, the upper and lower mold cavities are vertically aligned to create a combined cavity for forming a concrete highway barrier. | 06-11-2009 |
