Split-Face Block Mold
Abstract
The invention is to make a mold that will make a square
12.times.8.times.12 block that when split makes a full
6.times.8.times.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.

Claims
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.
Description
[0001] Mold for making mortar-less interlocking, split-face blocks,
made by changing and deleting some parts of the mold described in
U.S. Pat. No. 4,896,472, which makes the regular interlocking
block, so that the resulting mold will produce a
12''.times.8''.times.12'' block that can be split into
6''.times.8''.times.12'' split-face block and/or produce a
16''.times.8''.times.16'' block that can be split into two
8''.times.8''.times.16'' split-face blocks.
OBJECTIVE OF THE INVENTION
[0002] The objective of the invention is to build mortar-less,
interlocking, split-face blocks for construction of residential
dwellings and commercial buildings that require no skilled
labor.
BACKGROUND OF THE INVENTION
[0003] The invention relates to a building block and a system to
facilitate the construction of buildings, walls, cross walls and
the like without the need of special equipment or techniques. The
essential idea is to provide a full block and a system using the
full and two other types of interlocking blocks, the basic system
being three blocks. The blocks are designed to firmly lock together
and thus the construction does not require the traditional mortar
or cement to bond it together. This is due to the selection and
position ears protruding from at least the full block and grooves
in all the blocks that fit on said protruding ears. As a result, it
is possible to interlock said blocks in parallel, longitudinally or
transversely. Thus, with this system any simple or complex
structure may be built.
[0004] This application claims a benefit of an earlier provisional
application 360/839,200 filed Aug. 22, 2006. Also applicants are
elderly, one is 78 and the other is 80 so we wish to ask for and
expedited application process.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0005] The system comprises the combination of two basic building
blocks: a full block; and a half block.
[0006] These blocks should be manufactured with precision for
interlocking without the use of mortar. Load-bearing structures can
be built therewith.
The Full Block
[0007] As shown in FIG. 1, the full block is a rectangular
configuration of two spaced, parallel end walls and two spaced,
parallel side walls extending longitudinally of the block between
the therefore transverse end walls. The side and end walls have
respective external faces 101, 102 and define an open-ended
internal cavity extending between top and bottom faces 108,109,
respectively, of the walls and, therefore, of the open-ended
internal cavity.
[0008] The middle web 103 extend transversely of said block and,
therefore, parallel to it end walls between internal faces of the
side walls for separating the open-ended internal cavity into two
end cavities of substantially equal size of one end wall, one
internal face of one end wall, one internal face of one middle web,
and the intervening internal faces of side walls.
[0009] An ear 107 on a central web protrudes from the top face 108,
each ear being of substantially the same dimensions. Each ear has a
transversely extending surface 104 delimiting the extent of said
ear toward said central web and oppositely disposed, longitudinally
extending surface 114, each delimiting the extent of said ear
toward the proximal wall.
[0010] A groove is in the internal face of the end and side walls
of each end cavity. Each said groove extends from the bottom face
109 toward the top face 108 at least as far as the ears 107 project
from the top face 108. Each groove is defined by a groove face 100
and adjacent opposite edges 106.
[0011] The side edges 106 of the groove in each end wall are each
spaced from the external face 101 of the proximal side wall a
distance x substantially the same as the distance from the
longitudinally-extending surfaces 114 of the ears 107 respectively
to the same, proximal side wall faces. Each transversely-extending
surface 104 of each ear is spaced from the external face 102 of the
proximal end wall a distance Y substantially one half the external
length of a side wall minus the distance Z of the face of the
groove 100 Z in the proximal end wall to said external face 102 Z
of said end wall. The side edge 106 Z proximal the end wall of the
groove in each said side wall is substantially the same distance ZX
from the external face 102 Z of said proximal end wall as the
distance X of each longitudinally-extending surface 114 of each ear
to the external face 101 of the proximal side wall.
[0012] As a result, as shown in FIG. 1, an ear and groove of three
adjacent blocks A, B and D or B, C and E can be male-female
interlocked with external side and end faces of one bloc flush in a
longitudinal orientation, like block A, B and D, or transverse
orientation, like blocks B, C and E. The full block is such,
therefore, that three such blocks in sequence are adapted to form a
running bond of longitudinal or transverse orientation of the
sequential full blocks. In the longitudinal orientation, each
groove 100AD, 100BC in each end wall of one full block D
respectively male-female interlocks with one ear 107AD, 107BD of
each of the other two full blocks a, B the external faces 102 of
the end walls of the other full blocks A, B being in mating
relationship at 102 and the external faces 101 of the side walls of
each full block being parallel and respectively flush with the
external faces of the side walls and one groove 100 CE in one side
wall of one full block E respectively male-female interlocks with
one said ear 107BE, 107CE of each of said other two full blocks B,
C, the external faces of side walls 101 of full E block being
transverse to the external faces of the side walls 101 of at least
one of said other two full blocks B, C.
[0013] In other words each groove extending from the bottom toward
the top face at least as far as the ears project from the top face
is positioned, shaped and dimensioned so that an ear and groove of
adjacent block can be male-female interlocked with one external
face of one block flush with an external face of another block foe
either longitudinally or transverse orientations of the blocks.
Mold Design
[0014] In the manufacture of conventional blocks only one bar 400B
is used for the cores. The bar 400B is located along the top face
of a mold for concrete blocks to support steel cores 401B to form a
cavity or hollow in a concrete block. The mold method herein
described uses twin, i.e. two parallel-spaced core bars 400A for
supporting steel cavity-forming 401A in a block forming press mold.
The positions of the twin bars 400A can be approximately 6 mm from
opposite longitudinal edges (114 in FIG. 3) of the protruding ear
107 to a position of approximately 3 mm with relation to the
external edge of the steel core.
[0015] Molding guides 407 in FIG. 4 on sections of the twin bars at
the area of the top face 403A and extend downward between the steel
cores 401A to the frits levels defined by top face 404A (108 in
FIG. 4) of said block aside from the ear projections. These are in
the 6 mm space between the twin bars 400A and the longitudinal
sides face 408A of the projections at 403A as delimited by the
steel cores 401A. The molding guides 407 are removable.
[0016] The contours are such that each external face has at least
one protruding portion 150 and at least one receding portion 152,
the side external faces each having two of each such potions. The
depth from and into the block of the protruding and receding
portion of the contours together define an average face (only one
shown) at 154 of each wall which is shown in phantom because not
real. The average face at 154 corresponds to the face from which
various distance have heretofore been described as being
measured.
[0017] In the embodiment of FIG. 2, the average face of the walls
corresponds with the non contoured portion of the side and end
external faces 101', 102' at the ends of each wall and also at the
middle of the side walls. A marker groove 156 extends parallel to
the contours at the middle of the side faces to mark this location
for alignment with an edge of an end or side face of another full
block in a construction of such blocks. This helps get the external
faces of the block flush in transverse orientation of the blocks
and helps position the blocks in a construction for the grooves and
ears to interlock.
[0018] The protruding and receding portion of the contours on
opposite end and side faces of the block are complimentarily
positioned for nesting with those of another full block similarly
oriented relative to the top and bottom faces when complementary
end or side faces of the blocks mate. This prevents relative
movement of the blocks transverse of the contours and, when there
are two such blocks with the ears and grooves thereof interlocked,
too, adapts the block for forming rigid structure.
[0019] It will be understood that various other characteristics and
features of the invention are apparent from the drawings that such
variations of any characteristics or features of the invention as
may occur to one of ordinary skill in the art are contemplated by
the following claims to the invention.
