The herein disclosed invention pertains to interlocking construction blocks which may be arranged as desired to form a structure. More specifically, the invention pertains to a series of self-aligning block arranged to form straight or angled wall structures. Terminal and central channels in each construction block form a uniform channel shape for correspondence with a similarly uniform shaped peg which will guide the channels and therefore the construction blocks into alignment.
Concrete construction blocks are advantageous in construction of walls for their ease of manufacture and construction, reduced material cost, durability, and insulating properties. Without proper alignment and reinforcement, a wall constructed from concrete construction blocks will lose stability, allow leaks, and be more prone to structural failure and associated negative outcomes that present risks to the safety of individuals and property.
To provide a stable hold between concrete blocks, mortar or grout is typically applied between the gaps of each block to set the blocks in place and prevent shifting. Use of mortar or grout presents a number of disadvantages. If the blocks have been placed incorrectly or the structure or wall formed is uneven or skewed by poor block placement, the entire structure or must be broken down and the spent materials discarded or cleaned before reformation of the structure or wall is reattempted. Further, heavy equipment and machinery used or maneuvered during construction operations, which is common during building projects, may cause vibration or settlement of the structure or wall foundation which can cause wall blocks to shift out of proper alignment. This problem is more common when the vibration or settlement occurs before the mortar or grout dries to set the construction blocks in place. Such disadvantages are costly as the create delays in construction, upsets in construction schedules, and often requires the spent building materials to be discarded and replaced.
A considerable amount of time is taken by construction crews to carefully arrange and properly set construction blocks in place. In many cases a considerable amount of calculation and measurement must be undertaken to ensure the finished structure is accurately constructed. Thus, it should be apparent that the foremost problem concerning construction of structures and walls with concrete construction blocks is ensuring proper alignment of the construction blocks during construction of a wall or other structure.
Another problem of wall construction with concrete blocks is construction of walls adjoining corner or perpendicular walls. Generally, an outer wall is created by stacking blocks end-to-end in stacked rows above each other with mortar applied between each end-to-end block and each ascending row of blocks. A corner or adjoining wall may be created, depending upon whether the blocks have been stacked in parallel columns or staggered rows, by arranging blocks perpendicular to the axis of the outer wall, applying mortar, and stacking each block along the new wall. In general, the formation of a perpendicular wall depends upon the arrangement of the outer wall blocks.
There is a disadvantage in laying of blocks of adjacent perpendicular walls in parallel columns because a flush internal wall surface is created between the adjacent walls. In order to create an adjacent perpendicular wall in such a situation, mortar must be either applied directly upon the outer wall itself to affix new perpendicular blocks to the outer wall or the new projecting wall must be formed at a column interrupting the progression of the outer wall. With either method, forming walls at a ninety-degree angle (90°) in such a situation is considerably difficult. Differences in applied mortar thickness can deflect the desired angle sufficiently to cause imperfections or cracks at the surface of the adjoin walls that may require the new perpendicular wall to be repaired or even deconstructed after the defect has been discovered. Such a problem is not only costly in time but in cost of supplies and man hours.
Forming walls by laying blocks in staggered rows, by extending each successive block partially beyond the end of the blocks above and below allows blocks to be stacked perpendicularly within a wall and allows the blocks to project outward from the outer wall creating a starting point for placing staggered blocks for creating of a perpendicular internal wall. However placing a perpendicular block within the outer wall creates a break in the staggered sequence of the outer wall blocks, making it difficult to form corners at the end of a section of the outer wall.
Another disadvantage typical concrete blocks used in wall construction is in the placement of reinforcement rods or rebar to reinforce the wall sections. Generally, rebar is placed within the inner cells of construction blocks to maintain the structural integrity of the wall while allowing the air pockets created by such cells to remain for expansion and contraction due to changes in external temperature. In such cases cement or grout must be placed within the cells of the blocks along with the rebar in order to hold the rebar and effect such structural reinforcement. If the bond between the cement or grout and the rebar or the bond between the cement or grout of the inner walls of the block cells should fail, the section of rebar used will become useless for reinforcement.
Yet another disadvantage of present concrete block wall constructions is the lack of stability when such a wall is subjected to sustained or frequent gusts of winds such as gale winds or hurricane winds which exceed sixty-four knots or one-hundred eighteen kilometers per hour (seventy-four miles per hour). Concrete walls, being fabricated of concrete blocks, create solid wall surfaces with no passages for channeling of wind through the wall. Such walls typically are constructed by placement of mortar between each brick often lack stabilizing factors sufficient to withstand the perpendicular forces exerted upon them by gale or hurricane force winds. When such walls are exposed to such high winds, the flat walls must deflect inward to absorb the wind forces, which may cause the wall to crack or crumble damaging the wall structure and presenting risk of injury and damage to persons and damage property within.
In light of such disadvantages, there is presently a need for a construction block which will align itself as the wall is constructed and which will allow perpendicular or internal walls to be formed without an offsetting corner formation. A need also exists for an expedient means of reinforcing a wall to reduce the incidence of structural failure without the need of slowing or stopping work.
The present invention is directed to a series of self-aligning construction blocks which provide an expedient means of reinforced wall formation. Generally, the self-aligning construction blocks comprise rectangular linear blocks, corner blocks, and half blocks formed of any suitable material. However, these blocks will typically be formed of cast or aerated concrete.
The linear blocks and corner blocks comprise two elongate side ends and two shorter terminal ends. Each linear block is formed with an internal channel having a polygon shape such an hourglass shaped channel and a terminal polygon shaped channel such as a trapezoidal shaped channel. The terminal channel when placed into horizontal opposing abutment with an adjoining terminal channel of an adjacent block form a polygon shaped slot in the same configuration as that of the internal polygon shaped channel.
Each corner block is formed with at least one lateral polygon channel and at least one terminal polygon shaped channel. The lateral and terminal polygon shaped channels of the corner blocks provide a means for creation of corners, internal walls, and wall junctions which can be fixed within the linear progression of an outer or inner wall for additional stability.
The half blocks are cubic in shape and are provided for use in conjunction with the rectangular linear and corner blocks. The cubic half block comprise two to four polygonal shaped channels and maintain proper block advancement in wall construction. After creation of a wall junction or corner, the half blocks may be inserted into the wall progression to reset the pacing of block placement.
An elongated polygonal shaped peg such as an hourglass shaped peg is further provided for a solid fit within the polygonal shaped channels and polygonal shaped slots formed by the terminal lateral channels of each block. The specially shaped polygonal shaped peg will allow easy alignment and connection with adjacent blocks to one another by facilitating the driving of each block into alignment to one another. The elongated shape of the peg is capable of feeding through multiple polygonal shaped channels and slots of blocks placed vertically adjacent to one another in order to affix the vertically stacked blocks in alignment to one another and prevent the shifting of the blocks during wall construction.
In the event that the blocks are placed out of horizontal alignment to each other for wall progression, the polygonal shaped channels and slots of the blocks provide a means to slidably drive the misaligned blocks into linear alignment to each other by the insertion of a peg through the horizontally adjacent polygonal shaped channels to interact with the slanted faces of the polygonal shaped channels. Similarly, in the event that vertically stacked adjacent blocks are placed out of alignment to a vertically adjacent row of blocks or the progression of a row of blocks begins to shift out of alignment, the misaligned blocks may be aligned by insertion of the peg through the vertically adjacent polygonal shaped channels and slots which will drive and hold the vertically stacked blocks in alignment.
Each terminal, lateral, and polygonal shaped channels of the construction blocks are oriented at a sufficient desired distance between the terminal corners of each block to provide a uniform and flush alignment when coupled to adjacent construction blocks. Hollow cells and sleeves running through the self-aligning blocks may be provided for creation of air pockets for compensation of wall expansion and contraction due to changes in temperature and for passage of length of rebar for wall enforcement. The polygonal shaped channels of the blocks and polygonal shaped peg may be formed to create cavities of desired sizes, such as hourglass shaped channels and slots. The cavities may be sized to create an optional air pocket within the blocks and the cavities may cooperate with the elongated shapes of the cells and sleeves to allow for rebar passage and the pouring of concrete to fill the sleeves, hollow cells, and cavities spaces to create a pillar therein for further reinforcement against high velocity winds.
These and other objects, advantages, and features of this invention will be apparent to those skilled in the art from a consideration of this specification, including the claims and drawings herein.

Each block 10 is defined by polygonal shaped channels, shown as trapezoidal shaped channels 16, 17, which are fashioned of overhanging edges 22 wherein inwardly formed outwardly slanting faces 23 project inward to create channels 16, 17. The meeting of adjacent channels 16, 17, wherein the overhanging edges 22 of the adjacent blocks 10 abut one another, form a wedge shaped inward projection similar to projection 20 of channel 18 which defines the abutting polygonal shaped slot, shown as hourglass shaped slot 21.

Terminal channels 16 and channel 18 traverse through terminal ends 1 and the center of linear block 11, respectively, along the same plane as to allow passages to be created between horizontally and vertically adjacent blocks 10 and create a flush external surface for wall formation. Terminal channels 16 when placed near the terminal channel 16 of another block 10 on the same horizontal row creates a slot 21 to allow for passage of the peg 14 to slidingly engage with faces 23 of channel 16 to affix linear block 11 in place and cause self-alignment with the horizontally adjacent blocks 10. Similarly, the channel 18 of linear block 11 when placed adjacent to the channel 18 or the slot 21 of a vertically adjacent blocks 10 allows for the passage of peg 14 through each channel 18 and slot 21 vertically aligned relative to each other to affix linear block 11 in place and cause self-alignment with the vertically adjacent blocks 10.
Now referring to
Terminal channel 16 of corner block 12 is centrally located upon terminal end 1 in order to provide for uniform alignment between horizontally and vertically adjacent blocks 10. Lateral channel 17 is positioned off-center a sufficient distance upon elongate side 2 so as to allow channels 16 of horizontally adjacent blocks 10 to abut and form slot 21 for alignment and affixing with the passage of peg 14 therethrough and to create a flush outer corner 6.
Extended sleeve 26 is formed in a narrow elongate shape in order to facilitate positioning, insertion, and passing of a section of rebar 27 there through. The narrow nature of extended sleeve 26 allows for the passage of rebar 27 through sleeve 26 as well as vertically adjacent channels 18, slots 21, hollow cells 24, and sleeves 26 which may be partially out of alignment with sleeve 26. The combination of the narrow elongate space of sleeve 26 leaves a passage narrow enough to create a fixed space within the vertically adjacent channels 18, slots 21, hollow cells 24, and sleeves 26, wherein in the event rebar 27 becomes dislodged from its grouting within sleeve 26, it will be pinned within the narrow space of sleeve 26 and the spaces created by the vertically adjacent channels 18, slots 21, hollow cells 24, and sleeves 26. Further a section of rebar may additionally be passed through channels 16 and 18 of vertically adjacent blocks 10.
Terminal channels 16, traversing terminal end 1, lateral channels 17, traversing elongate side 2, and hollow cell 24 and extended sleeve 26, traversing the central region of block 12, traverse through block 12 along the same plane as to allow passages to be created between horizontally and vertically adjacent blocks 10. Terminal channels 16 and lateral channels 17 when placed near the terminal channel 16 of another block 10 on the same horizontal row creates slot 21 to allow for passage of the peg 14 to affix and cause self-alignment between corner block 12 and an adjacent block 10. Insertion of peg 14 into slots 21 formed by the intersection of either the terminal channels 16 of corner block and a linear block 11 or the lateral channel 17 with the terminal channel 16 of a linear block 11, as desired to create corner 6, will maintain the formation of corner 6 in place even when exposed to vibration or shifting of the ground by nearby movement.

Terminal channels 16 and lateral channels 17 when placed near the terminal channel 16 of another block 10 on the same horizontal row creates slot 21 to allow for passage of peg 14 to affix and cause self-alignment between junction block 12a and an adjacent block 10. Insertion of peg 14 into slots 21 formed by the intersection of either the terminal channels 16 of junction block 12a and a linear block 11 or the lateral channel 17 with the terminal channel 16 of a linear block 11, as desired to continue form perpendicular junction 7 and continue the formation of intersecting walls 4, 5, will maintain the intersection in place even when exposed to vibration or shifting of the ground by nearby movement.
Similarly, when forming a perpendicular junction 7 by placing blocks 10 in a staggered arrangement, slot 21, formed by the abutting of channels 16, 17 of junction block 12a and linear blocks 11, may be placed vertically adjacent to channels 18 of a vertically adjacent linear block 11. The uniform design of channel 18 and slots 21 allows for passage of peg 14 through channel 18 and slot 21 to affix and self-align the junction block 12a in place with the vertically adjacent linear block 11.

Terminal and lateral channels 16, 17 when placed near the terminal channel 16 of another block 10 on the same horizontal row will create hourglass shaped slot 21 to allow for passage of peg 14 to affix and cause self-alignment between T-junction blocks 12b, 12c and an adjacent block 10. Insertion of peg 14 into slots 21 formed by the intersection of either the terminal channels 16 of T-junction blocks 12b, 12c and a linear block 11 or the lateral channels 17 of T-junction blocks 12b, 12c with the terminal channels 16 of a linear block 11, as desired to adjoin intersecting walls 4, 5, will maintain the intersection in place even when exposed to vibration or shifting of the ground by nearby movement.
Similarly, when forming a perpendicular junction 7 by placing blocks 10 in a staggered arrangement, slot 21, formed by the abutting of channels 16, 17 of T-junction blocks 12b, 12c and linear blocks 11, may be placed vertically adjacent to channels 18 of a vertically adjacent linear block 11. The uniform design of channel 18 and slots 21 allows for passage of peg 14 through channel 18 and slot 21 to affix and self-align the T-junction blocks 12b, 12c in place with the vertically adjacent linear block 11.

Blocks 13, 13a-c are employed to facilitate proper progression and junctioning of walls 4, 5 without the necessity of cutting or reorientation of blocks 10. Channels 16 run through block 13 along the same plane to allow passages to be created between horizontal and vertically adjacent blocks 10. As best seen in

Once peg 14 has been inserted through channel 18 and slots 21, the frictional forces between the abutment of faces 19 and faces 25 and faces 23 and faces 25 will force the adjacent blocks 10 into alignment and grippingly hold the adjacent blocks 10 in staggered alignment and resist external forces which would otherwise cause the shifting of blocks 10 out of alignment. In the event of a misaligned placement of vertically adjacent blocks 10 wherein channel 18 or slots 21 of the vertically adjacent blocks 10 do not properly align, the insertion of peg 14 will force the vertically adjacent blocks 10 into alignment by sliding faces 19, 23 of channels 18 and slots 21, respectively, against the faces 25 of peg 14 which will in turn push and drive the channels 18 and slots 21 for proper alignment.
Alternatively, in forming a wall 4, 5 in parallel columns of stacked blocks 10, during linear formation of walls 4, 5, the channel 18 or slot 21 of the top block 10 will be placed into a vertically adjacent orientation with the channel 18 or slot 21 of the series vertically adjacent blocks 10 below it. When peg 14 is inserted through vertically adjacent channels 18, the wedge shaped inward projection 20 and faces 19 forming the polygonal shape of channels 18 will slidably mate with edges 28 and faces 25 of peg 14. When peg 14 is inserted through vertically adjacent slots 21, the abutting edges 22 and slanting faces 23 of the horizontally adjacent blocks 10 forming slots 21 will slidably mate with edges 28 and faces 25 of peg 14.
Once peg 14 has been inserted through channels 18 or slots 21, the frictional forces between the abutment of faces 19 of channel 18 and faces 25 of peg 14 or faces 23 of slot 21 and faces 25 of peg 14 will force the adjacent blocks 10 into alignment and grippingly hold the vertically adjacent blocks 10 in a parallel column alignment and resist external forces which would otherwise cause the shifting of blocks 10 out of alignment. In the event of a misaligned placement of vertically adjacent blocks 10, the insertion of peg 14 will force the vertically adjacent blocks into alignment by sliding faces 19 of channel 18 against the faces 25 of peg 14 and push and drive the channels 18 or slots 21 into proper alignment with each other.
During linear formation of an outer wall 4, in order to facilitate internal wall 5 formation wherein the outer wall 4 may continue its linear progression thereafter, a T-junction block 12b having two lateral channels 17, T-junction block 12c having two terminal channels 16, or a T-junction half block 13a having three terminal channels 17 will be positioned perpendicular to the axis created by the linear progression of outer wall 4. In forming an internal wall 5 with T-junction block 12b, terminal end 1 having terminal channel 16 will be oriented to project the terminal channel 16 of T-junction block 12b inward from outer wall 4, wherein the lateral channels 17 of T-junction block 12b will oriented to linearly align with the terminal channels 16 of the linear block arrangement of outer wall 4. In forming an internal wall 5 with T-junction block 12c, elongate side 2 having lateral channel 17 will be oriented to project lateral channel 17 of T-junction block 12c inward from outer wall 4, wherein the terminal channels 16 of T-junction block 12c will be oriented to linearly align with the terminal channels 16 of the linear block arrangement of outer wall 4. In forming an internal wall 5 with T-junction half block 13a, the central channel 16 of the three adjacent channels 16 will be oriented to project the central channel 16 inward from outer wall 4, wherein the outside terminal channels 16 of T-junction half block 13a will be oriented to linearly align with the terminal channels 16 of the linear block arrangement of outer wall 4.
After insertion of T-junction blocks 12b, 12c, or half block 13a, channels 16, 17 will project inward at a substantially ninety-degree angle (90°) to the linear axis of outer wall 4, wherein additional linear blocks 11 or linear half blocks 13 will begin the creation of an inner wall 5. Furthermore, use of T-junction blocks 12b, 12c, or half blocks 13a in internal wall 5 formation removes the need to spread mortar along the inner portion of outer wall 4 which thus prevents internal wall 5 alignment problems due to mortar deflection.
When an internal wall 5 is created by use of T-junction blocks 12b, 12c, or half blocks 13a, the staggered progression of outer wall 4 may be effected. Linear half block 13 may be used to correct the offset created by the insertion of the shorter length of the terminal end 1 of blocks T-junction blocks 12b, 12c, or half block 13a into the progression of outer wall 4 and allow fbr continuation of the staggered or parallel column end-to-end progression of the inner 5 and outer walls 4 so as to prevent issues with formation of subsequent outer corners 6 and perpendicular junctions 7. Thereafter, walls 4, 5 may be continued by addition of linear blocks 11 and linear half blocks 13.
After formation of an internal wall 5, additional internal walls 5 may be created by adding additional corner blocks 12, junction blocks 12a, or T-junction blocks 12b or 12c. Linear blocks 11 and half blocks 13 may then be added as desired to create rooms and hallways within a structure by creation of additional internal walls 5.

Mortar or grout may be spread upon the outer surface between blocks 10 to provide a fixed hold between vertically and horizontally adjacent blocks 10 or to fix rebar 27 in place within cavities 30, hollow cells 24, and extended sleeves 26. Application of mortar or grout upon blocks 10 provides reinforcement to the structural integrity of walls 4, 5 as well as insulation from temperature changes through the small spaces between each horizontal and vertically adjacent block 10. Further, concrete may be poured within the vertically adjacent hollow cells 24, extended sleeves 26, and cavities 30 to form internal concrete pillars and thus produce walls 4, 5 which are capable of withstanding hurricane force winds. The poured concrete will flow into the vertically adjacent cells 24, sleeves 26, and cavities 30 and harden to form a solid concrete pillar within walls 4, 5 which provides a solid central retaining structure capable of withstanding perpendicular gust forces in excess of sixty-four knots or one-hundred eighteen kilometers per hour, seventy-four miles per hour.
