Definitions

  • Interlocking blocks are assembled in longitudinally staggered rows.
  • the blocks are planar on their bottom side and include webs with interlocking protrusions on their upper side.
  • the protrusions coact with the webs on adjacent rows of blocks to locate and hold the blocks in position.
  • Corner blocks and end blocks are also provided so that a series of walls may be constructed without the need for the usual mortared joints.
  • the protrusions are chamfered and have associated therewith an excessmaterial-receiving groove to compensate for manufacturing tolerances.
  • a completed wall may be grouted through interconnecting cavities in the hollow blocks to provide additional strength.
  • the mortarless or interlocking blocks provided thus far have been deficient in several respects.
  • the typical prior art interlocking block is manufactured by the usual moldiing process and then the various interconnecting grooves and protrusions are formed into the block by sawing or other forming techniques. Such a block becomes impractically expensive for most applications.
  • An exemplary embodiment of the invention incorpo rates an interlocking building block having two longitudinalplanar upright side walls. a plurality of transverse spacing webs and interlocking means protruding from one face of the block.
  • the term web should be taken as including a projection extending at right angles from the interior surface of a side wall. At least one of the webs must connect between the side walls. but the other webs in a given block may be partial.
  • the webs have integral protrusions extending be yond the face of the block and defining interlocking means in the form of notches in the protrusions. The notches engage the webs on adjacent blocks to position and hbld the blocks.
  • the inside surfaces of the outer most webs are spaced from the ends of the side walls by a distance which. in sum, is equal to the distance between the facing vertical walls of the notches on the protrusions.
  • the resulting blocks interlock in alternate rows with a staggered configuration.
  • the block may be assembled with mortar. mortarless. or with grout or glue as will be described more fully hereinafter.
  • An exemplary configuration for the blocks incorporates a symetrical configuration with four transverse webs. It is to be understood however. that unsymetrical positioning of the webs and web numbers in excess of the 2, 3, and 4 web configurations that are specifically treated hereinafter are equally a part of the invention.
  • Each web incorporates a protrusion with an interlocking notch.
  • the notches have vertical faces which open toward the center of the block.
  • Each interlocking means comprises a right angularly configured notch in the protrusion of the web beyond the planar upper face of the block.
  • the substantially vertical wall of the block is chamfered to produce a wedging action when in cooperative alignment with the web on the adjacent block.
  • a material receiving groove Directly vertically below the vertical wall of the notch is a material receiving groove. This groove is for the purpose of receiving material which is scraped off or otherwise severed from either of the cooperating surfaces of the interlocking blocks.
  • first course of blocks is layed with the flat planar bottom face supported from a concrete floor slab or similar surface.
  • the blocks are layed end to end with the ends of the side walls in engagement.
  • the second course of blocks is then placed on the first course by inserting a block with half of its length overlapping each of two lower blocks. With this orientation the inclined surfaces of the interlocking means guide the block as it is lowered vertically onto the previously layed course. if there is any out of alignment condition resulting from manufacturing conditions or other causes. the sloping surfaces will cause a sufficient amount of material to be removed by abrasion and similar mechanical action so that the blocks become fully engaged.
  • corner blocks have a configuration according to the interlocking blocks over approximately one-half of their length and have a corner interlock configuration over the remainder of their length.
  • the corner interlock configuration incorporates a substantially square vertical opening through the end of the block with recesses at 90 increments.
  • a key. positioned to engage the notches on a cooperating corner block, is located on the upper or lower surface of each corner block and at the innermost edge of the opening.

  • the sum of the distances from the ends 46 and 50 of the side walls 44 to the inner edges of the outer webs 42 and 36 is equal to the spacing between the facing vertical faces of the interlocking means 38 and 40. Further the sum of the distances from the face 39 to the end 46 and the face 4] to the end 50 is substantially equal to the spacing between the vertical faces 35 and 37.
  • the blocks will mate and interlock irrespective of the use of three webs and irrespective of the spacing between webs 34 and 42, so long as the spacing between webs 34 and 42 are consistant for each block used and interlocked together. So with this construction. unequal spacings between the webs and the ends of the blocks can be used and still obtain the correct interlocking as illustrated in FIGS. 12 and 14.
  • FIGS. 1, 2. l and 17 illustrate several forms of the four web blocks that will be used for exemplary purposes hereinafter.
  • the four webs are symetrically oriented.

The sum of the distances from the ends 68 and 70 to the inner edges 6l and 63 of the outer webs 60 and 62 is equal to the spacing between the surfaces 57 and 59 of the substantially vertical portions of the notches in the interlocking means 56 and 58.
  • FIG. 8 wherein a plurality of four symetrically webbed blocks 74 are illustrated in engagement with one another.
  • the inner webs 52 and 54 have their interlocking means 56 and 58 in engagement with outer webs 60 and 62 on blocks in the vertically related course of blocks. This produces engagement of the ends 68 and 70 of the side walls 72.
  • the outer interlocking means 64 and 66 engage the webs 54 and 52 of the vertically related blocks. The size relationship makes it possible to invert the uppermost course of blocks to present a planar upper surface as is illustrated.
  • the upper horizontal exterior edges of the block have horizontal chamfered edges I40 and the vertical exterior edges have chamfered edges 142. These chamfered edges enhance the appearance of the block and form a drip edge to prevent water from entering joints.
  • the blocks 74 have two planar side walls which side walls terminate in planar edges 68, 70 and 84.
  • the webs are coplanar with the bottom edges 84 and therefore the only portion of the block which deviates from a planar exterior configuration are the protrusions of the interlocking means.
  • This configuration for the block makes it possible for it to be molded in a conventional mold with no undercuts. It is therefore possible to form all the interlocking structure and all the other structural features of the block by a molding process alone. 7
  • the corner block 88 Over substantially one half of its length, the corner block 88 has a configuration identical to that for the block 74. The remaining portion of the block 88 is configured for terminating the block at a corner.

  • the tang 102 on the end block is received against the inner face of wall 90 on the block 88 thus maintaining the integrity of the interlocked relationship.
  • the interlocking means 56 comprises a protrusion 110 from the web 52 which extends beyond the planar upper edges of the walls 72.
  • the protrusion is generally rectangular in configuration and has a chamfered surface I12 on the substantially vertical wall 114.

It is to be understood that in some situations the material may be removed from both the web 62 and the protrusion 110. In extreme mis-alignments, it is possible that the entire protrusion 110 will be broken away; however, since there are four such interlocking devices on each block there will still be adequate interlocking contact between the vertically related blocks to maintain them in position.
