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.

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
