FIELD OF THE INVENTION
[0001] The invention generally relates to a building block for use in construction. More
specifically, the invention relates to a building block for use in interlocking with
similar blocks for constructing a building.
BACKGROUND OF THE INVENTION
[0002] Building blocks are widely used in the building and construction industry. The building
blocks are mainly used as load-bearing and non-load bearing materials, wherein they
are laid on stack or running bond using cementitious materials. This is due to properties
of the building blocks such as, but not limited to, high strength, toughness, stability
and high chemical durability. Interlocking building blocks are used in constructing
buildings, due to numerous advantages over conventional building blocks.
[0003] The building blocks are produced using different process. Modem clay blocks are formed
using processes such as, but not limited to, soft mud process, dry press, and extrusion.
The dry press method is similar to mud blocks but starts with a much thicker clay
mix and therefore it forms more accurate, sharper-edged blocks.
[0004] Currently, the blocks are manufactured using a fixed set of materials which are expensive.
The processes used in manufacturing the blocks are also rigid and there is little
scope for changing the processes. For some applications, the properties of the block
may not satisfy all the requirements.
[0005] Currently, assembling interlocking building blocks requires significant amount of
effort. There are also several design issues which hinders the assembly of the interlocking
building blocks. Also the interlocking building blocks need extra support such as,
an adhesive and a rebar for strengthening the construction. Also, the usability of
the interlocking blocks is limited due to the inefficient designing of male and female
interconnects to interlock a plurality of interlocking blocks.
[0006] Therefore, there is a need to develop an interlocking block, which is functional,
easy to construct and cost effective.

[0021] Generally speaking, pursuant to various embodiments, the invention provides details
regarding the structure of a building block for use in interlocking with a plurality
of similar building blocks for constructing a building.
[0022] Referring to the figures and in particular to FIGS. 1-4, wherein FIG. 1 illustrates
an exemplary representation of an upper isometric view of a building block 100 in
accordance with an embodiment of the invention, FIG. 2 illustrates a lower isometric
view of building block 100 in accordance with an embodiment of the invention, FIG.
3 illustrates a plan view of building block 100 in accordance with an embodiment of
the invention, and FIG. 4 illustrates an elevation view of building block 100 in accordance
with an embodiment of the invention. As shown in FIG. 1, building block 100 includes
a front face and a rear face, such as front face 102 and rear face 104. The front
face and the rear face are vertically oriented and are substantially planar surfaces.
In some exemplary implementations, the front face and the rear face can be designed
as one or more of, but not limited to, a smooth surface and a patterned surface.
[0023] Building block 100 further includes an upper face and a lower face such as an upper
face 106 and a lower face 108 as shown in FIG. 1. The upper face can be a horizontally
inclined planar surface as shown in FIG. 1. In an embodiment, the upper face can include
one or more horizontal surfaces at different elevations. For example, the upper face
includes a first portion 118 and a second portion 120, where first portion 118 is
placed at an elevated level relative to second portion 120, as shown in FIG. 1. In
an exemplary embodiment, the lower face is substantially complementary to the upper
face, as shown in FIG. 2. In some embodiments, the upper face and the lower face of
building block 100 are suitably modified to form an interlocking bond with a corresponding
lower face and upper face of cooperating building blocks when stacked upon each other,
wherein the cooperating building blocks are similar to building block 100. The upper
face and the lower face can have one or more patterns in order to facilitate interlocking
between the cooperating building blocks. In an embodiment, the one or more patterns
include one of, but not limited to, a running pattern, a crossed pattern and a lobed
pattern.
[0024] In accordance with various embodiments of the invention, building block 100 includes
at least one substantially vertical hollow (web) such as, but not limited to, a vertical
hollow (web) 110a and a vertical hollow (web) 110b. Further, the at least one substantially
vertical hollow (web) extends from the upper face to the lower face of building block
100 as shown in FIG. 1. In various embodiments, parameters such as shape and size
of the at least one substantially vertical hollow (web) can be customized as desired.
For example, the at least one substantially vertical hollow (web) can be designed
to have a shape such as, cylindrical, cuboidal, semi cylindrical shape and the like.
For example, the at least one substantially vertical hollow (web) has a cuboidal structure
as shown in FIG. 1. In accordance with the embodiment, the at least one substantially
vertical hollow (web) is designed to be perpendicular to the upper surface and the
lower face of building block 100. The aforementioned design of the at least one substantially
vertical hollow (web) facilitates in the formation of vertical channel, when a plurality
of building blocks, similar to building block 100, are stacked upon each other. Further,
in accordance with the embodiment shown in FIG. 1, building block 100 includes two
substantially symmetrical vertical hollows (webs). It will be apparent that building
block 100 can include different numbers of substantially vertical hollows (webs).
For instance, building block 100 can include one substantially vertical hollow (web).
Alternately, building block 100 can include three or more than three substantially
vertical hollows (webs).
[0025] Building block 100 further includes at least one substantially horizontal channel
such as, but not limited to, a horizontal channel 112. Horizontal channel 112 is disposed
along at least one of the upper face and the lower face of building block 100. The
at least one substantially horizontal channel can be designed as one or more structures
such as, a concave structure, a concave polygonal structure and the like. Variations
in design of the at least one substantially horizontal channel would be apparent to
those ordinarily skilled in the art. In an exemplary embodiment, the at least one
substantially horizontal channel has a concave structure as shown in FIG. 1. In an
exemplary embodiment, the at least one substantially horizontal channel is disposed
on at least one of the upper face and the lower face of building block 100. In accordance
with the embodiment, the at least one substantially horizontal channel is disposed
between the front face and the rear face of building block 100. In an exemplary embodiment,
the at least one substantially horizontal channel is disposed at the center portion
of at least one of the upper face and lower face. In the embodiment illustrated in
FIG. 1, building block 100 includes two substantially horizontal channels as shown,
wherein each of the upper face and the lower face comprises one substantially horizontal
channel that is of a concave structure. It is possible that building block 100 includes
only one substantially horizontal channel, wherein the at least one substantially
horizontal on one of the upper face and the lower face of building block 100. Further,
the at least one substantially horizontal channel is designed such that when a first
building block and a second building block similar to building block 100 are stacked,
the upper face of the first building block mates with the lower face of the second
building block resulting in the formation of a horizontal channel such as a horizontal
channel 152 as shown in FIG. 4.
[0026] Building block 100 further includes a first end and a second end (not numbered in
figures). At least one of the first end and the second end includes at least one header
face. The header face is one of a substantially planar face, a male header face such
as a male header face 126 and a female header face such as a female header face 128.
Each of the first end and the second end can include one or more header faces. For
example, the first end can include one male header face and the second end includes
one female header face as shown in FIG. 1. The male header face protrudes outwards
at one of the first end and the second end of building block 100. For instance, the
male header face protrudes outwards at the first end as shown in FIG. 3. The female
header face protrudes inwards at one of the first end and the second end of building
block 100. For instance, the female header face protrudes inwards at the second end
of building block 100 as shown in FIG. 3. The design of the male header face and the
female header face is such that the male header face of one building block can interlock
with the female header face of a cooperating building block, wherein the blocks are
identical or similar to building block 100. In various embodiments, the male header
face and the female header face include one or more patterns in order to facilitate
interlocking between the cooperating building blocks. In an embodiment, the one or
more patterns include one of, but not limited to, a running pattern, a crossed pattern
and a lobed pattern. In an embodiment, the male header includes a first stepped pattern
projecting outwards as shown in FIG. 3. In an embodiment, the first stepped pattern
includes a central contact surface such as a central contact surface 130 and other
contact surfaces disposed symmetrically about the central contact surface such as,
but not limited to, a first contact surface 132 and a second contact surface134 as
shown in FIG. 3. In an embodiment, the female header face includes a second stepped
pattern substantially complementary to the male header face. In an embodiment, the
second stepped pattern includes a central groove such as a central groove 136 and
other grooves disposed symmetrically about the central groove such as, but not limited
to, a first groove 138 and a second groove 140 as shown in FIG. 3. It will be apparent
that there could be numerous variations in the design of the first stepped pattern
and the second stepped pattern and as such those variations would be apparent to those
ordinarily skilled in the art. For instance, the number of steps could be different
than those illustrated in the figures. Alternately, the design of the first stepped
pattern and the second stepped pattern can be other than that illustrated in the figures.
[0027] In accordance with various embodiments of the invention, when a first building block
and a second building block similar to building block 100 are mated adjacent to each
other the interlocking bond is formed. Precisely, when the male header face of the
first building block is mated with the female header face of the second building block,
the interlocking bond is formed due to the complementary nature of the patterns between
the male header face and the female header face. In an exemplary embodiment, the interlocking
bond is formed when contact surfaces such as central contact surface 130, first contact
surface 132 and second contact surface 134 of the male header face mate with grooves
such as central groove136, first groove 138 and second groove 140 of the female header
face. In an exemplary embodiment, interlocking the plurality of building blocks similar
to building block 100 forms a network of vertical and horizontal channels (described
in conjunction with the description of FIG. 10). In an exemplary embodiment, at least
one of the vertical and horizontal channels is designed to be used for inserting at
least one of a plurality of water pipes and a plurality of electrical conduits.
[0028] Building block 100 as illustrated in FIGS. 1-4 is a normal building block for use
in constructing the building in accordance with various embodiments. There could be
numerous variations in the design of building block 100 based on end-use of building
block 100. In various embodiments of the invention, building block 100 is used to
construct the normal portions of a building such as, but not limited to, corners,
intersections, crossings and connections. Depending on the end-use, building block
100 has a particular design, wherein building block 100 can be designed as one of,
but not limited to, a corner block, an intersection block, a cross block and a connection
block. For instance, if building block 100 is designed to be used for constructing
a corner portion of the building, building block 100 is designed as a corner block
as illustrated in FIGS. 5A-5D. FIGS. 5A-5D illustrate different views of the corner
block, wherein FIG. 5A illustrates an isometric view of a left corner block 510 in
accordance with an embodiment of the invention, FIG. 5B illustrates a plan view of
the left corner block 510 in accordance with an embodiment of the invention, FIG.
5C illustrates an isometric view of a right corner block 520 in accordance with an
embodiment of the invention, and FIG. 5D illustrates a plan view of the right corner
block 520 in accordance with an embodiment of the invention. In accordance with various
embodiments of the invention, the header face at the first end of the corner block
is at right angles to another header face at the second end as shown in FIG. 5A. Further,
the header face at one of the first end and the second end is one of the male header
face and the female header face. For instance, the corner block can have header faces
as illustrated in FIGS. 5A-5D. In an exemplary embodiment, the header face at the
first end of the corner block can be aligned at one or more of, a left side and a
right side with respect to the header face at the second end as shown in FIG. 5A and
FIG. 5C.
[0029] In another instance, building block 100 can be designed to be used at one or more
three way (T) intersections while constructing the building. For example, building
block 100 is designed as a T-block that can be used at the one or more T intersections
as shown in FIGS. 6A-6F. Referring now to FIGS. 6A-6F, which illustrate different
views of the T-block in accordance with various embodiments of the invention. In particular,
FIGS 6A and 6B illustrate an isometric view and a plan view of a left T-block 600,
FIGS. 6C and 6D illustrate an isometric view and a plan view of a right T-block 610,
and FIGS 6E and 6F illustrate an isometric view and a plan view of a normal T-block
620. In an exemplary embodiment, the T-block includes an additional header face at
one of the first end and second end. Further, the additional header face is disposed
at right angles to the header face at one of first end and second end, as shown in
FIGS. 6E. The additional header face can be one of a male header face and a female
header face based on a requirement. In an exemplary embodiment, the additional header
face is a female header face 602 disposed at right angle to a female header face 604
at the first end of the T-block, while the second end includes the male header 606
as shown in FIG. 6A.The T-block can have one or more variations such as, but are not
limited to, a left T-block as shown in FIG. 6A and a right T-block as shown in FIG.
6C. The T-block is used at one or more T-intersections while constructing the building.
In an exemplary embodiment, the additional header face is placed at an angle of 180
degrees to the header face at one of the first end and the second end, as shown in
FIG. 6E and FIG. 6F. Other variations in design of the T-block will be apparent to
those ordinarily skilled in the art.
[0030] In yet another instance, building block 100 can be designed to be used at one or
more four way intersections while constructing the building. For example, building
block 100 can be designed as a cross block to be used at the one or more four way
intersection as illustrated in FIGS. 7A-7B, which illustrate different views of the
cross block in accordance with various embodiments of the invention. In particular,
FIG. 7A illustrates an isometric view of the cross block, and FIG. 7B illustrates
a plan view of the cross block. In an exemplary embodiment, the cross block includes
two additional header faces at one of the first end and the second end, wherein the
two additional header faces are at right angles to one of the male header face and
the female header face at the first end, as shown in FIG. 7A. The two additional header
faces can be one or more of a male header face and a female header face similar to
the male header and the female header face of building block 100. In an exemplary
embodiment, a first end of the cross block includes a first female header face 702,
a second female header face 704 and a third female header face 706 as shown in FIG.
7A. In accordance with the embodiment shown in FIG. 7A, second female header face
704 and third female header face 706 are aligned at right angles to first female header
face 702. Furthermore, the second end of the cross block includes a male header face
708 as shown in FIG. 7A. In an exemplary embodiment, the cross block is used at one
or more four-way intersections during the construction of the building.
[0031] In still another instance, building block 100 can be designed to be used at one or
more connecting points during the construction of the building. In an example, building
block 100 is designed as a connecting block to be used at one or more connecting points.
The one or more connecting points include, but not limited to, gaps of different dimensions
at points of termination while constructing the building. Turning now to FIGS 8A-8F,
which illustrate perspective views of the connecting block in accordance with various
embodiments of the invention. In particular, FIG. 8A illustrates an isometric view
of a normal connecting block 800 while FIG. 8B illustrates a plan view of normal connecting
block 800. FIG. 8C illustrates an isometric view of a negative connecting block 810,
while FIG. 8D illustrates a plan view of negative connecting block 810. FIG. 8E illustrates
an isometric view of a positive connecting block 820, while FIG. 8F illustrates a
plan view of positive connecting block 820. The connecting block can be at least one
of a normal connecting block, a positive connecting block and a negative connecting
block. In an exemplary embodiment, the normal connecting block, as shown in FIG. 8A
and FIG. 8B is a compact version of building block 100 and includes a single substantially
vertical hollow (web) such as the substantially vertical hollow (web) of building
block 100. In another exemplary embodiment, the positive connecting blocks (similar
to that shown in FIGS. 8E-8F) and negative connecting blocks (similar to that shown
in FIGS. 8C-8D) include identical header faces at the first end and the second end.
In an exemplary embodiment, the identical header face can be one of a male header
face (as shown in FIGS. 8E-8F) and a female header face (as shown in FIGS. 8C-8D).
In an exemplary scenario, the one or more connecting blocks are used to fill small
uneven gaps created at the one or more points of termination while constructing the
building.
[0032] Building block 100 can also be designed to be an end block (not illustrated in figures),
wherein one of the first end and the second end includes a header face that is a substantially
planar face. Further, in such a design one of the upper face and lower face can be
a substantially planar face. In addition, in such a design only one of the upper face
and the lower face includes the substantially hollow (web) channel. Numerous variations
in design of building block 100 are possible and as such those variations would be
apparent to those ordinarily skilled in the art.
[0033] Referring now to FIG. 9, which illustrates a perspective view of the building wall
constructed using the plurality of similar building blocks in accordance with various
embodiments of the invention. In order to enable the construction of the building
wall, one or more types of building block 100 are used. In an exemplary construction
of the building wall shown in FIG. 9, building blocks similar to, but not limited
to, a normal building block for use at a normal position such as a normal position
902, a corner block for use at a corner position such as a corner position 904, a
T-block for use at an intersection such as an intersection 906a and an intersection
906b, a cross block for use at a crossing such as a crossing 908 and a connecting
block for use at a connecting position such as a connecting position 9 10a, connecting
position 910b and connecting position 910c. In an embodiment of the invention, a plurality
of building blocks similar to building block 100, are designed to be used for constructing
one of a stacking bond and a running bond without the use of cementitious materials.
[0034] Referring now to FIG. 10, which illustrates the perspective view of a network of
horizontal channels and vertical channels within the building wall constructed using
the plurality of similar building blocks in accordance with various embodiments of
the invention. In an exemplary scenario, at least one horizontal channel such as a
horizontal channel 152 is formed when the upper face of building block 100 interlocks
with the lower face of another building block similar to building block 100. This
occurs when the building blocks are stacked upon each other as shown in FIG. 4. In
another exemplary scenario, the at least one substantially vertical hollow (web) of
building block 100 matches with the at least one substantially vertical hollow (web)
of the plurality of building blocks, similar to building block 100, concentrically
when stacked upon each other, thereby creating at least one vertical channel such
as a vertical channel 150 as shown in FIG. 10. The network of the vertical channels
and the horizontal channels is used for adding at least one of horizontal and vertical
reinforcements such as, but not limited to, water pipes and electrical conduits.
[0035] In accordance with various embodiments, building block 100 can be produced using
one or more of materials such as, but are not limited to, natural raw materials, recycled
materials, raised-derived materials, polymers, clay, sand-cement, concrete, silica-lime,
geopolymer and similar composite materials. Further, in accordance with various embodiments,
building block 100 is produced using techniques such as, but are not limited to, uniaxially
cold pressing, biaxial cold pressing, dry pressing, semi-dry pressing, compacting,
cold isostatic pressing, hot pressing, extrusion molding, injection molding, compression
molding, gel casting, slip casting and tape casting.
[0036] Various embodiments of the invention described different structural aspects of a
building block for use in constructing a building wall. The building block offers
a convenient way to construct buildings and structures. The building blocks interlock
with a plurality of similar building blocks and create a strong bond without using
cementitious materials. The plurality of building blocks when assembled, readily form
a network of vertical and horizontal channels for installing reinforcements such as
electrical conduits and water pipes. The building blocks can be manufactured using
a variety of materials which enables a user to use an appropriate material according
to a desired application, thereby reducing cost of the structure.
[0037] Those skilled in the art will realize that the above recognized advantages and other
