## Abstract

A construction block system that includes a block with slanted edges that coact with contiguous blacks to define spaces or grooves for receiving cementitious substances. Cooperatively aligned channels in the upper and lower edges coact with longitudinally extending walls perpendicularly mounted to a base assembly. An adjustable mechanism provides for leveling of the base assembly to ensure proper installation of the lowermost row of blocks. Subsequently rows are aligned and leveled with a leveling tool assembly that is also partially received within the cooperative channels.

## Claims

### Claim 1

A construction block system including a block comprising:
A) first and second walls kept at a parallel and spaced apart relationship with respect to each other and including first and second, upper and lower edges, said first and second upper edges including first and second upper slanted walls, and each of said first and second walls further including first and second side edges that extend perpendicularly from said first and second, upper and lower edges, and said first and second side edges include first and second side edge slanted walls and said first and second lower edges including first and second lower slanted walls;
B) third and fourth walls kept at a parallel and spaced apart relationship with respect to each other and connected to said first and second walls to form a block with a substantially rectangular cross-section, and each of said third and fourth walls including third and fourth upper and lower edges, respectively, said third and fourth walls being perpendicularly mounted to said first and second walls, said third and fourth upper edges each including at least one longitudinally aligned first channel, and said third and fourth lower edges including at least one longitudinally aligned second channels; and
C) a base alignment tool assembly including at least one longitudinally extending sheet, said at least one longitudinally extending sheet including a plurality of through openings disposed along the entire length of said at least one longitudinally extending sheet, wherein said at least one longitudinally extending sheet includes means for horizontally leveling said at least one longitudinally extending sheet, said base alignment tool assembly further including at least one guiding wall perpendicularly mounted to said at least one longitudinally extending sheet, said at least one guiding wall having cooperative dimensions to be receivable within said at least one Longitudinal aligned second channel of the lowermost row of blocks of a wall structure to keep said blocks in alignment;
D) a plurality of vertical grooves defined by said first and second side edge slanted walls of horizontally contiguous blocks;
E) at least one longitudinal groove defined by said upper and lower slanted walls of vertically contiguous blocks; and
F) a cementitious substance lodged in said grooves.

### Claim 2 (depends on 1)

The block system set forth in claim 1 further including:
G) a fifth wall having fifth upper and lower edges said fifth wall being perpendicularly mounted between said first and second walls at predetermined distances from said third and fourth walls defining first and second internal cavities and said fifth wall further including fifth upper and lower edges having third and fourth channels, respectively, longitudinally aligned with said at least one first and second channels, respectively.

### Claim 3 (depends on 1)

The block system set forth in claim 1 further including:
H) a row leveling and reinforcement tool assembly including at least one straight elongated rigid member partially receivable within said at least one first and third longitudinal aligned channels and within said at least one second and fourth channels, except for said blocks forming the lowermost row.

### Claim 4 (depends on 3)

The block system set forth in claim 3 wherein said third and fourth walls include third and fourth upper slanted external walls, that coact with contiguous horizontally disposed blocks defining a space for lodging cementitious substance.
