Abstract
A concrete masonry unit having a top surface with a splitting pattern formed therein. The splitting pattern has a splitting groove which intersects at least one recessed region formed in the top surface.
Claims24
A concrete masonry unit comprising a top surface and a bottom surface, said top surface having formed therein a splitting pattern comprising a splitting groove which extends to, and forms at least a partial border of, at least one recessed region formed in the top surface, and wherein said top surface and said bottom surface are parallel.
A concrete masonry unit comprising a top surface having first and second opposed side edges, and including a first recessed region located at the first side edge.
A concrete masonry unit comprising:
- a) a lower face;
- b) an upper face generally parallel to the lower face;
- c) opposed front and rear faces, each being generally perpendicular to the upper and lower faces, and joining the upper and lower faces;
- d) opposed first and second side faces, each being generally perpendicular to the upper and lower faces, and joining the upper and lower faces;
- and
- e) a splitting pattern formed in the upper face, comprising
- i) a first triangularly-shaped, recessed splitting region located at the intersection of the upper face and the first side face;
- ii) a second triangularly-shaped, recessed splitting region located at the intersection of the upper face and the second side face;
- and
- iii) a splitting groove extending generally parallel to the front and rear faces and joining the first and second recessed splitting regions.
A method of forming a concrete masonry unit, said concrete masonry unit comprising:
- a) a lower face;
- b) an upper face generally parallel to the lower face;
- c) opposed front and rear faces, each being generally perpendicular to the upper and lower faces, and joining the upper and lower faces;
- d) opposed first and second side faces, each being generally perpendicular to the upper and lower faces, and joining the upper and lower faces;
- and
- e) a splitting pattern formed in the upper face, comprising
- i) a first triangularly-shaped, recessed splitting region located at the intersection of the upper face and the first side face;
- ii) a second triangularly-shaped, recessed splitting region located at the intersection of the upper face and the second side face;
- and
- iii) a splitting groove extending generally parallel to the front and rear faces and joining the first and second recessed splitting regions,
- said method comprising the step of forming said first and second recessed splitting regions and said splitting groove by compressive action on the top surface of the unit prior to curing of the unit.
