Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to poured concrete walls and, more particularly, to an insulated form assembly for a poured concrete wall.
2. Description of the Related Art
Conventional concrete wall construction is well known in the art of building a structure. For example, in a house, basement walls may be constructed of poured concrete. To build a poured concrete wall, a temporary form is prepared in the desired shape of the wall. In the past, the form was made from plywood or metal. Recently, the forms have been made from other materials, including foamed plastic. The form is usually constructed at the site of the structure.
The form is maintained in an upright position during the construction process using extensive bracing. For example, 2×4 studs may be used as braces. After the form is prepared, concrete is poured into the form and allowed to harden. The form is then removed from the hardened concrete wall.
Recently, concrete walls have been constructed from a combination of materials, to improve their insulating efficiency. In an insulated concrete wall, the wall is made from a combination of an insulating material and concrete. The insulating material is a permanent form, which becomes an integral part of the wall. Usually, the form is made from an insulating material, such as a dense plastic foam. Advantageously, a wall section may be pre-assembled from a plurality of forms and transported to the construction site for assembly into the desired shape of the structure. An example of a preassembled insulated form assembly is disclosed in U.S. patent application Ser. No. 09/108,741, filed Jul. 1, 1998 entitled “Insulated Form Assembly For Poured Concrete Wall”, which is hereby incorporated by reference. After the walls are assembled, passageways within the insulated form assembly are filled with concrete to complete the walls of the structure. The resulting insulated concrete wall has the strength of a poured concrete wall, with the additional advantages of providing thermal and acoustical insulation, an air and vapor barrier, and exterior wall sheathing. The disadvantage of such an insulated concrete wall is that another object cannot be directly attached to the wall due to the tensile characteristics of the insulated material. Therefore, there is a need in the art to provide an insulated form assembly for a poured concrete wall that allows attachment of an object to the wall with improved tensile characteristics.
SUMMARY OF THE INVENTION
It is, therefore, one object of the present invention to provide a new and improved insulated form assembly for a poured concrete wall.
It is another object of the present invention to provide an insulated form assembly for a poured concrete wall that includes an integral attachment member.
To achieve the foregoing objects, the present invention is an insulated form assembly for a poured concrete wall. The insulated form assembly includes a plurality of insulated forms. Each insulated form includes two generally planar opposing panels and a plurality of interior segments interconnecting the panels and defining a plurality of passageways. each panel includes at least one channel and an attachment member disposed within the channel to allow an object to be attached thereto.
One advantage of the present invention is that an insulated form assembly is provided for constructing an insulated poured concrete wall that offers improved strength, thermal and acoustical insulation, and acts as an air and vapor barrier. Another advantage of the present invention is that the insulated form assembly provides an attachment member for attaching an object to the wall. Yet another advantage of the present invention is that a shape of the attachment member improves retention of an object mounted to the wall. Still another advantage of the present invention is that the attachment member may allow drainage for moisture within the poured concrete wall.
Other objects, features and advantages of the present invention will be readily appreciated as the same becomes better understood after reading the subsequent description when considered in connection with the accompanying drawings.

12
includes two generally planer opposing panels
14
. Each form
12
also includes a plurality of interior segments
16
interconnecting the panels
14
and forming a plurality of passageways
18
, which are later filled with poured concrete, in a manner to be described. The panels
14
and segments
16
are made from an insulated foam material, such as Styrofoam. It should be appreciated that the panels
14
and segments
16
are integral, unitary, continuous and formed as one-piece.
Each form
12
also includes a supporting member
20
positioned within the passageway
18
and extending generally perpendicular to the panels
14
to provide additional structural strength to the finished insulated poured concrete wall. In this example, each panel
14
is approximately 30″ long, 12″ wide, and 2″ deep. Similarly, each form
12
is approximately 30″ long, 12″ wide and 10″ deep. Preferably, an exterior surface of the panel
14
includes a decorative pattern (not shown), such as to resemble a concrete block.
Each form
12
further includes an interlocking portion
22
for fittingly engaging with another form
12
in a manner to be described. In one embodiment, the interlocking portion
22
is a pair of alternating projecting members
24
extending longitudinally and recessed portions
26
positioned on either one of an upper edge
28
or a lower edge
30
of the panel
14
.
Each form
12
also includes at least one, preferably a plurality of attachment channels
32
extending generally vertically through each panel
14
. Preferably, the attachment channels
32
are at a seam
33
on opposed sides. The attachment channels
32
are spaced preferably every 10 inches or evenly spaced in other types of forms
12
. The attachment channel
32
has a generally rectangular shape. Each form
12
also includes an attachment member
34
disposed within each attachment channel
32
. Preferably, the attachment member
34
is made from a rigid material such as metal. The attachment member
34
has a generally rectangular closed shape. The attachment member

a
. For example, in finishing an interior of a structure, drywall may be secured to the wall through the attachment member
34
by the fastener
35
a
. In another example, a stud (not shown) may be attached to the attachment member
34
by the fastener
35
a
, such as in framing an interior wall. If additional surface area for attaching purposes is desired, the form
12
may include an attaching strip
36
held in a groove
38
, in either one of the upper edge
28
or the lower edge
30
of the panel
14
. Preferably, the attaching strip
36
is made of a rigid material such as metal and has a generally rectangular closed shape or a generally open U-shape. The attaching strip
36
may include a longitudinally extending rib (not shown) for reinforcement. It should be appreciated that the attaching strip
36
is similar to the attachment member
34
. It should also be appreciated that in interconnecting forms
12
, one longitudinally extending edge of the attaching strip
36
fits within the groove
38
of one form
12
, and the other longitudinally extending edge of the attaching strip
36
fits within the groove
38
of a vertically adjacent form
12
.
To construct the insulated form assembly
10
, a plurality of individual forms
12
are interconnected, such that each projecting member
24
is seated within a corresponding recessed portion
26
, so that each form
12
is aligned and locked. If an attaching strip
36
is utilized, one longitudinally extending edge of the attaching strip
32
is placed in the groove
38
in the upper edge
28
of one form
12
, and the attaching strip
36
fits within the corresponding groove
38
of a vertically adjacent form
12
. It should be appreciated, that the forms
12
are arranged so that an attachment channel
32
in a form
12
is in vertical alignment with an adjacent form
12
, to form a single, unitary attachment channel
32
. A plurality of interconnecting forms
12
are interconnected, until the desired height is attained. The attachment member
34
is placed in the attachment channel
32
. It should be appreciated that the width and/or height of the insulated form assembly
10
can be extended by connecting form assemblies
10
to each other.
The pre-assembled insulated form assembly
10
may include at least one band or strip
46
circumscribing the insulated form assembly
10
, to hold it together during shipping, handling and installation at the construction site. Alternatively, a fastener such as a screw could be screwed through top and bottom attaching strips
36
in place of bands
46
. Preferably, the band
46
is made of a metal material, although it could be of another rigid material, such as a plastic. It should be appreciated that the ends of the band
46
may be secured by a retaining mechanism (not shown), such as a clip, as is known in the art. Advantageously, one end may be looped prior to inserting onto the retaining mechanism, to form a handle. Advantageously, the insulated form assembly
10
is lightweight for ease of transportability and maneuverability.
To build a structure using the insulated form assemblies
10
, a building site (not shown) is excavated and prepared, as is known in the art. Footings (not shown) for supporting the structure are installed corresponding to the shape of the structure. For example, the footings may be of concrete block. A pre-assembled insulated form assembly
10
is then placed in the desired position. Individual pre-assembled insulated form assemblies
10
may then be secured together as previously described. Each insulated form assembly
10
is braced with braces (not shown).
Preferably, a catwalk (not shown but well known in the art) is secured to the insulated form assembly
10
. The catwalk provides accessability to pour concrete into the insulated form assembly
10
. The catwalk includes a hanger (not shown), which supports a plank (not shown) positioned on a vertical surface of the hanger. For example, the hanger may be secured to the insulated form assembly
10
by hanging the hanger over an end of the attachment member
34
protruding from the uppermost edge of the form
12
. The hangers may be spaced an appropriate distance apart.
After the installed insulated form assembly
10
is in place, and braced, concrete is poured into the passageways
18
. A worker (not shown) can walk along the plank while directing the pouring of the uncured concrete cement. The concrete cement flows through and fills each channel
18
within the insulated form assembly
10
. After the concrete cures or hardens, the banding and bracing may be removed from the completed insulated poured concrete wall.
The present invention has been described in an illustrative manner. It is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.
Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the present invention may be practiced other than as specifically described.
