Split-Face Block Mold

Abstract

The invention is to make a mold that will make a square 12×8×12 block that when split makes a full 6×8×12 and a half block that will be used in a construction system based on the combined use of split-face mortar less blocks designed to lock together. There are two basic blocks, the full, and half block, with which any desirable structure can be built. The full block has protruding ears and grooves. The half block also has protruding ears and grooves. There are standard measurements between groove face in all blocks and standard measurements between ears in the full block which correspond to the measurement of the groove faces. This provides for a wide array of interlocking positions.

1 . A building system comprising of two types of split face interlocking blocks, whereby construction of structures therewith does require mortar to lay the first course for the Initial leveling of the wall; also grouting the cells with rebar, and the ring beam, the two types of blocks comprising:
 a. A split face full block of rectangular configuration: two spaces, parallel end walls and parallel side walls extending longitudinally of the block between the end walls, the end and side wall faces middle web extending transversely of the block and parallel to the end walls between internal faces of side walls for separating two end cavities of equal size, each end cavity being defined by an internal faces of one end wall, one internal face of the middle web, and the intervening internal faces of the side walls; and ears on middle web, the ears being confined to and protruding from middle web and being the only protrusion from the top face, each ear being the same dimensions; and a groove in the internal face of each of the end and sidewalls of each cavity being non-contiguous, each groove extending from the bottom face toward the top face at least as far as the ears projecting from the top face and being positioned, shaped and dimensioned so that an ear and groove of adjacent blocks can be male-female interlocked with one external face of one block flush with an external face of another block for either longitudinally parallel or transverse orientation of the respective blocks.   b. The full split face block wherein one external side face has a split face and one external side face has the same configuration as the external end faces of the full block are contoured along axes perpendicular to the top and bottom faces of the full block so that each face has at one protruding and one receding portion, the respective protruding and receding portions mating with each other so that when an external end or side face of one full block is in mating relationship with an external face of another full block, relative movement of the blocks transversely of the axes is prevented.   c. The split face full block wherein the one external face and external end faces of the full block are contoured along axes perpendicular to the top and bottom faces of the block so that each face has at least one protruding and at least one receding portion, the respective protruding and receding portion mating with each other so that the split face block is adapted to form a rigid structure. This is achieved when at least two other full blocks are interlocked between respective ears and grooves respectfully.   
   
   
       2 . A split face half block of square configuration comprising four walls, each having an external face and internal face, the internal face defining one internal cavity, two of the external faces of the half block each having the same configuration as the external faces of the end walls of the full block, and at least one groove in the internal face of the half block extruding from one end of the cavity for male-female fitting with one ear of the full block in the construction of a structure. 
   
   
       3 . Wherein the split face half block further comprise a groove on three internal faces thereof, the grooves being non-contiguous. 
   
   
       4 . Wherein the split face half block does have protruding ears. 
   
   
       5 . And further comprising a plurality of the split face block piled upon another to define a cavity for reinforcing with rebar to form a column and pillar. 
   
   
       6 . The building system according to  claim 2 , wherein the two external faces of the split face half block each have the same dimensions and each groove is located in the same position with respect thereto.
