ADJUSTABLE POST-TO-SUBSTRATE EMBED SYSTEM
Background Of The Invention
1. Field of the Invention
[0001] The present invention relates to systems and assemblies to
embedding
structures into concrete.
2. Related Art
[0002] Conventional methods for connecting, for example, guard
rails in concrete
structures, such as concrete structures comprising a slab or stem wall in
commercial and
residential buildings, have difficulties in regard to simplicity, cost and
sturdiness. Such
systems typically provide an embedded mounting plate for railing systems to
weld to once
the finished concrete is installed.
[0003] Figs. lA and 1B are views showing a typical conventional
embed plate system
100. System 100 is for affixing a guide rail 102, typically to edges of a
concrete structure.
The system 100 includes an embedding plate assembly 103 including a mounting
plate 104,
legs 106 and base flanges 108.
[0004] As seen in Fig. 1A, the plate assembly 103 is installed in
concrete so that the
mounting plate 104 is substantially flush with the concrete surface level. In
this position, the
legs 106 descend vertically away from the mounting plate 104 and the flanges
108 can be
used, for example, to support the plate assembly 103, or to float in the
concrete, such that,
when the concrete has hardened, the flanges108 provide an anchoring function.
[0005] Upon hardening of the concrete, the surface of the
mounting plate can be
cleaned to provide a clean surface onto which a bottom portion of posts 102 of
a railing
system can be welded.
[0006] This system has disadvantages, one of which is that a
welding connection
requires two pieces of steel, and requires the mating surfaces of the welded
parts to be very
clean, which may be a problem when concrete has recently covered one of the
components
to be welded.
[0007] Another conventional welding plate unit 200 is shown in
two perspectives in
Figs. 2A and 2B. This structure 200 has a two-level construction with a bottom
plate 202
1
CA 03206554 2023- 7- 26

WO 2022/164458
PCT/US2021/016053
having mounting holes 204 that allow the bottom plate 202 to be bolted onto a
surface of the
concrete landing, and an offset upward post 206 that leads to a mounting plate
208.
[0008] In this unit 200, the offset arrangement allows for
placement of the railing
further out toward the perimeter of the landing than the bolts, providing more
usable space
on the patio. Once waterproofing and concrete installation is complete, the
railing is welded
to the mounting plates to provide the railing system.
[0009] Other known solutions for post-to-concrete attachment
solutions include
securing with expansion anchors, specific hi-lo bolts, core mount, or block
out installation--
all of which, for various reasons, are generally less than ideal in a shallow
depth slab. The
expansion anchors increase the risk of breaking up the concrete, resulting in
a bad structural
connection. Such failures are likely to be deep in the slab and invisible from
the surface.
[0010] Thus, there is a need for an adjustable post-to-substrate
embed system which
is safe, cost effective and easy to install.

SUMMARY OF THE INVENTION
[0011] An object of the invention is to provide a lightweight,
inexpensive and durable
post-to-substrate embed system. The examples provided below will generally
discuss
attachment of a railing post with a railing base plate. Examples of railing
posts are, for
example a guardrail post, or fence post. Thus, the discussion of, for example,
railings, or
railing posts, equally applies to guardrails, guardrail posts, fences and
fence posts, which all
may have similar base plates. The term "railing" herein may refer to a
guardrail or a fence,
and the term "railing post," therefore, may refer to a guardrail post or a
fence post, or other
similar structures.
[0012] In accordance with an aspect of the present invention,
there is provided a
system including a plate with anchors, placed to align with railing base plate
mounting holes,
a bracket for adjustably placing the plate on an edge of a concrete
containment form, which
may be, for example, a pan, with adjustability, by which a consistent
placement for alignment
of the railing is achieved.
[0013] In accordance with another aspect of the present
invention, an adjustable
railing post-to-substrate embed system for anchoring a railing post having a
railing base with
plural railing base anchor holes includes: a plate, having anchor holes; a
plurality of nuts, a
first end of each nut being arranged proximate a respective one of the anchor
holes, the first
end of each nut being configured to be selectively and removably threadingly
engaged, via
the respective anchor hole, with one selected from the group consisting of:
respective upper
protective bolts, and respective bolts of the railing base; and a plurality of
anchors, each
being configured to adjustably threadingly engage a second end of a respective
one of the
nuts, distal the respective anchor hole, each of the anchors being
individually adjustable in
length by threadable engagement with the second end of the respective one of
the nuts, so
that the distance between an anchor and its corresponding anchor hole can be
modified
relative to the distance between another of the anchors and its respective
anchor hole. That
is, while the lateral spacing between the anchors is fixed, the depth of the
anchors is
adjustable.
[0014] In another aspect, each anchor comprises a lower bolt and
a washer.
[0015] In another aspect, the system further comprises: a bracket
having a bent end
configured to fixedly engage the bracket to an edge of a concrete containment
form via bent

PCT/US2021/016053
end screws, and configured to adjustably arrange the plate with respect to the
edge of the
metal concrete containment form by affixing the bracket to the plate.
[0016] In another aspect, the upper protective bolts are
configured to be arranged in
the first end of the nut, and then selectively removed after a hardening of
concrete in the
containment form, which can be for a slab, a stem wall or a concrete column.
[0017] In another aspect, the bracket is affixed to the plate by
a plate contact screw,
and wherein the bracket comprises a slot through which the plate contact screw
passes for
the adjustable arrangement of the plate with respect to the edge of the
concrete containment
form.
[0018] In another aspect, in a case in which the concrete has not
yet hardened the
selected group consists of the respective upper protective bolts.
[0019] In another aspect, in a case in which the concrete has
hardened, the selected
group consists of the respective bolts of the railing base.
[0020] In another aspect, each anchor comprises a lower bolt and
a washer, and the
concrete containment form comprises reinforcers, configured to provide
reinforcement to the
hardened concrete, the length of each anchor being adjustable prior to
applying the concrete
so as to avoid contact with the reinforcers, that is, to prevent conflict with
the structural steel
reinforcement prior to the concrete application.
[0021] In another aspect, each nut comprises first threading at
the first end, for
threadingly engaging a bolt, and second threading at the second end, for
threadingly
engaging a respective one of the anchors.
[0022] In another aspect, the plate is made of plastic.
[0023] In another aspect, the plate is made of metal.
[0024] In another aspect, the protective railing bolts and
railing base bolts are the
same.
[0025] In another aspect, the protective railing bolts and
railing base bolts are
different.
[0026] In another aspect, the concrete containment form comprises
a metal concrete
pour pan.
[0027] In another aspect, the railing comprises a guardrail.
[0028] In another aspect, the railing comprises a fence.

PCT/US2021/016053
[0029] Advantages of the present invention include providing a
simpler adjustable
railing post-to-substrate embed system that allows for precise and straight
guardrail or fence
installation while maintaining structural integrity. Other advantages are that
off the shelf
fasteners can be used, such as bolts, nuts and washers, a longer bolt can be
used when
depth and structural obstacles are not an issue.. Welding is not required.
Another
advantage is that the only two fabricated components are the plate, which can
be made of
plastic, and the bracket.
[0030] The system also provides for faster and stronger
installation and maintains
structural integrity, while preventing a false sense of security due to
concrete splitting
concrete delamination or oversized hole.
[0031] The present invention also prevents short-term and long-
term unintended
damage to edge bar and post tension cables that are typical with core drill
and wedge anchor
applications. Greatly reduced long-term cost of maintenance and ownership are
also
achievable.
[0032] The system provides flat plates with vertical nuts, and
bolts and washers
forming anchors, the depth of which anchors is easily adjustable by twisting
of a bolt of the
anchor into or out of the nut. This adjustability provides flexibility to
control the depth of the
anchors, for example around obstacles such as structural steel used in the
reinforcement of
concrete. The threaded anchor permits the adjustment of the depth of the
anchors for
deeper or shallower positions offering flexibility while maintaining adequate
holding power.
Depending on the application different length bolts can be used.
[0033] The flat washer at each anchor position offers a wide area
of resistance in a
360-degree direction distributing the stress to a larger area of the concrete.
Unlike a bent
anchor such as a "J-bolt" the area under stress is concentrated at the top
radius of the
anchor, causing the anchor to act as a wedge while exerting forces capable of
causing
concrete failure.

DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENTS
[0049] The present invention provides an adjustable railing post-
to-substrate embed
system that allows for precise and straight railing (such as a guardrail or a
fence) installation
while maintaining waterproofing membrane integrity. As will be developed
below, the
system uses, for example, a plate, that can be molded of plastic, with 4
anchors, placed to
match base plate mounting holes of a railing system. Also provided is a
bracket for placing
the system on an edge of a concrete containment form, which is shown for
example, in the
illustrated examples, as a metal concrete pour pan, with adjustability, which
allows for
consistent placement for alignment.
[0050] Figs. 3A and 3B show one instance main anchoring system
section of an
embed system of the present invention. Fig. 3A shows a main section 400 in a
mostly
assembled form, while Fig. 3B shows the component elements disassembled. The
main
section 400 is configured to eventually be embedded in concrete so as to be
able to accept
a bolt-on engagement between holes in a top plate thereof and bolts at the
base of a balcony
or landing system.
[0051] It should be noted that the main section 400 is
illustrated in Figs. 3A and 3B
and in other figures in a configuration that is used during installation in
the concrete. As will
be discussed in more detail below, the main section 400 will be modified after
being secured
in the hardened concrete so as to be able to engage with the bolts of the
railing.
[0052] The plate 402 is configured to lie across the top of the
concrete of the balcony
or landing. As can be seen in Fig. 3A the plate 402 is configured to extend
section 400 of
the embed system into a concrete floor by use of longitudinally extending
hexagonally cross-
sectioned nuts 404. The nuts 404 are long enough to provide interior threading
to accept
bolts at each end. In particular, the nuts 404 cooperate with the holes 403 of
the plate to
threadingly engage top bolts 406 and bottom bolts 408 at the tops and bottoms
of the nuts
404, respectively.
[0053] The plate 402, which is preferably made of a plastic
resin, allows precise
placement of threaded anchors, each formed by a bottom bolts 408 and a large
washer 410,
in their required respective locations, corresponding to the hole pattern of
the mating part.
Being made of a plastic resin allows the receiving plate 402 to isolate most
of the receiving
plate from moisture and conductivity. The material also sufficiently resists
compression
forces even though it is not made of metal. While plastic is preferred, the
invention is not
8
CA 03206554 2023- 7- 26

WO 2022/164458
PCT/US2021/016053
limited to plastic and other materials, such as metal, carbon fiber, etc.,
could be used to
make the plate.
[0054] The shape of the plate 402, for example with its opposite
indents 480, is
specifically designed to provide installers tool access to the normally hard
to reach space
around the anchors. This mitigates possible voids or cavities in the concrete
under the plate
and around the fasteners, ensuring adequate structural strength.
[0055] During installation of the embed system in the concrete,
the top bolts 406
function to keep the concrete and other debris out of the top female threaded
parts of the
nuts 404. As will be developed below, the top bolts 406 will eventually be
replaced by railing
bolts that secure a railing to the plate 402, with railing washers 800, after
the concrete has
fully hardened. Although the top bolts 406 are not present in the finished
product with the
railing, they perform an important function; because even a small amount of
concrete or
other debris in the top of the nuts 404 will foul the threading, affecting the
ability to engage
the railing bolts to the threads in the tops of the nuts 404.
[0056] The bottom of each nut 404 has female threading to accept
a bottom bolt 408
in cooperation with a wide washer 410, the combination of the bolt 408 and the
wide washer
410 forming an anchor. The washers 410 provide a wide surface area under the
concrete
and provide strength to the connection, particularly in the vertical
direction, between the
section 400 and the hardened concrete.
[0057] The anchoring system is designed as an assembly of
separate components,
which provides for less cumbersome shipping and packaging, as compared to the
prior art
systems.
[0058] The threadability of the bolts 408 and the nuts 404
provide the flexibility to
control the depth of the anchors around obstacles such as structural steel
used in the
reinforcement of concrete. The threaded anchor permits the adjustment of the
depth of the
anchors for deeper or shallower positions offering flexibility while
maintaining adequate
holding power. Depending on the application different length bolts can be
used.
[0059] The flat washer 410 at each anchor position offers a wide
area of resistance
in a 360-degree direction, which distribute stress forces to a wider area of
the concrete
relative to such an assembly without such washers.
[0060] Figs. 3C and 3D show an x-ray and sectional view,
respectively, of the nut 404.
As can be seen from these figures, the outer shell of the nut has a hexagonal
sectional

PCT/US2021/016053
profile; and, as discussed above, threadings 426 and 428 are provided within
the nut 404
starting at respective ends of the nut 404.
[0061] Fig. 3E is a plan view of the plate 402, having indents
480, corner holes 403
and receiving holes 403A.
[0062] Fig. 4 illustrates the use of four instances of the
section 400 in relation to a
concrete containment form, in this exemplary embodiment, a metal pan 600, into
which the
concrete is to be poured. As can be seen in Fig. 4, each section 400 is
affixed to an edge
of the pan using a bracket arm 500, illustrated by itself in Fig. 5.
[0063] The bracket arm 500 functions as a positioning arm with a
slotted channel 504
and provides the ability to adjust and align the position of the anchoring
system. This allows
an installer to maintain true alignment with adjacent anchoring systems,
regardless of
irregularities in the concrete form. The positioning bracket arm 500 can be
secured to a
variety of forming materials, using various mechanical fasteners depending on
substrate.
[0064] In the illustrated embodiment, shown, for example, in Fig.
5, the bracket arm
500 has two main portions, the horizontally extending portion 502 and the
vertically
extending portion 502A, to form a substantially right angled bracket. The
bracket arm 500
is affixed to the section 400 by the screws 412A going through the slot 504
and into the
holes 403A of the plate 402. The use of a slot 504 allows for adjustment of
the bracket prior
to a final tightening. The bracket arm 500 is affixed to the pan 600 using
screws 900 into
top and side holes 503 and 503A, respectively.
[0065] Fig. 6A is a detailed view of one instance of the assembly
formed by the
bracket arm 500 and the section 400 as installed in a pan 600. Returning to
Fig. 4, each
assembly is affixed to the pan as discussed above. Reinforcing shafts 602 are
arranged in
the pan 600. Such shafts provide additional strength to the concrete, once the
concrete has
hardened.
[0066] Fig. 6B is a view of the assembly formed by the bracket
arm 500 and the
section 400, in a disassembled state. Figs. 6C and 6D are exploded views of
this assembly.
Fig. 6E is a view of an assembled assembly formed by the bracket arm 500 and
the section
400, prior to the assembly being affixed to an edge of the pan 600. Note that
in Fig. 6B, the
lower bolts 408 and the large washers 410 have been set to different amounts
of extension.
This will be discussed below.

having been poured into the pan 600 and shows the configuration just before
the upper bolts
406 are to be removed for replacement by bolts that are associated with the

be discussed below, the upper bolts 406 are used to ensure the upper threading
of the nut
404 remains clean and in proper placement so that the railing bolts will be
able to thread
properly into the nuts 404. While typically different bolts 802 (see Fig. 8
below) would be
provided with the railing base, it is also understood that, if the upper bolts
are the same bolts
as the ones used for attachment of the railing, those same upper bolts 406
could be re-
inserted to secure the railing base, rather than be discarded in favor of new
bolts. The
bracket arm 500 secures the main section 400 in place until the concrete
hardens, after
which the brackets are removed before affixing the railing to the plate 402.
[0068] As can be seen in Fig. 7, the depth of the anchors (408,
410) differs on each
side of the illustrated main section 400. This may be used to avoid, i.e., go
around, obstacles
such as structural steel used in the reinforcement of concrete, for example
reinforcing shafts
602. The threaded anchor (408, 410) permits the adjustment of the depth of the
anchors for
deeper or shallower positions offering flexibility while maintaining adequate
holding power.
Depending on the application different length lower bolts 408 can be used.
[0069] Fig. 8 is a view showing a railing 705 with base plate 701
that has been affixed,
by railing bolts 802, to the nuts 404, not visible in this figure, using the
threading in the nuts
404 originally used by upper bolts 406. As can be seen in Fig. 8, washers 800
are now used
under the heads of the railing bolts 802 to ensure a tight fit. The system is
securely fastened,
along with the railing, in the concrete 700.
[0070] Installation of an embodiment of the embed system is
performed as follows:
plural instances of the assemblies formed by the bracket arm 500 and the
section 400 are
affixed, by the angled part of the bracket arms 500, to edges of the pan 600
having the
structural reinforcing shafts 602. This configuration is shown in Fig. 4. The
heights of the
anchors 408, 410 are adjusted as needed to avoid contacting any structural
reinforcing
shafts 602 or to avoid any other features of the pan 600. The concrete is then
poured into
the pan 600 to a height that is about level with the plates 402. Once the
concrete has cured,
the brackets 500 are removed, the plates are cleaned of any concrete, and the
upper bolts
406 are removed. The installation of the respective rail bases is effected
using bolts 802

and washers 800, as shown in Figs. 8 and 9A-9C. Alternatively, the upper bolts
406 can be
reused for this purpose.
[0071] Figs. 9A-9C are exploded and x-ray views that illustrate
how the railing 705
with base plate 701 line up with the main section 400 in attaching the railing
post to the main
section 400. Note that the washers 800 are not shown in Figs. 9A-9C to
simplify the
illustration.
[0072] Thus, while there have been shown and described and
pointed out
fundamental novel features of the invention as applied to preferred
embodiments thereof, it
will be understood that various omissions and substitutions and changes in the
form and
details of the devices illustrated, and in their operation, may be made by
those skilled in the
art without departing from the spirit of the invention. For example, it is
expressly intended
that all combinations of those elements and/or method steps which perform
substantially the
same function in substantially the same way to achieve the same results are
within the scope
of the invention. Moreover, it should be recognized that structures and/or
elements and/or
method steps shown and/or described in connection with any disclosed form or
embodiment
of the invention may be incorporated in any other disclosed or described or
suggested form
or embodiment as a general matter of design choice. It is the intention,
therefore, to be
limited only as indicated by the scope of the claims appended hereto.
