ABSTRACT:
SPONSORSHIP
This invention has not been made under any Federal or Independent Sponsorship and is the sole result of his own inventive efforts.
FIELD OF THE INVENTION
This invention relates generally to the construction aspect of forming poured concrete walls where the elements defining the concrete receiving cavity are formed from sheets of selected materials which are held in spaced relation through a combination of U and H-shaped web structures with additional corner members which similarly may be web joined, stand alone without joinder or are tie joined. Supporting sheets of selected materials are positioned within the U and H-shaped structures and corner members to define the concrete receiving cavity and the sheets may selectively remain in the finished wall with the remaining U, H-shaped structures and corner members remaining in the wall as attachment areas for additional wall coverings. The J-shaped member may be arranged either horizontally or vertically.
SHORT SUMMARY OF THE INVENTION
In the pouring of concrete walls as, typically in constructing of basements, a foundation, is initially provided with the wall being poured thereon and upwardly therefrom
In a first form of the invention, defining a horizontal usage, a base or first web member having U-shaped channels on its respective sides is anchored to the foundation with sheets of select materials being inserted therein as a first course. Comer posts, each consisting of a pair of U-shaped channels, arranged at some selected angle to one another, for example a 90 degree or less or greater angle, are arranged at corner locations to receive the ends of sheets of material. These corner posts may be joined in some manner or may be free standing. Upon the upper side edges of the first course of sheets, a web member having H-shaped channels is positioned to receive an additional sheet course. Progress to desired wall height is achieved through subsequent courses of sheets and H-shaped web members with a final U-shaped web member positioned on the uppermost of such courses.
In a second form of the invention which does not require different structural elements, but for differentiation defining a vertical usage, the initial U-channeled web is positioned on the foundation to) receive the first course of sheet material with the corner posts again located at respective corners to receive the ends of sheets. In this form, H-webbed channels are placed at the end of a first sheet of material to receive with additional sheets and H channels arranged along the length of wall. The sequence of structure extending from one corner to another is the positioning of the -shaped web upon the foundation, placement of sheets therein with an H-shaped web, now vertically positioned atop the U-Web and receiving the end of a sheet. This procedure extends the length of the wall and following the first course, the corner posts and vertical H-webs are positioned and the sheets are simply slide into the provided spacings.
Upon reaching desired height, a topping U-web caps the final sheet.
In each application, cutting of the webs and corners must taken into consideration.
BACKGROUND AND OBJECTS OF THE INVENTION
The formation of poured concrete walls is not new. The art of doing the same has changed from time-to-time, dependent upon the growth of material technology and, simply, more awareness and development of building techniques.
This is represented by the number of Prior Art references which have been cited in the Prior Art Statement.
Applicant is well aware of structures that included cross ties between the cavity providing sheets and his previous invention was directed to such a concept.
The present invention is believed to be a new and unique system which eliminates cross or tie bar connections, with the exception of and the only possible necessity being at the corner post locations.
The U and H channel members each provide a continuous, cuttable, member with the U and H openings of the channel members being selectively spaced with respect to one another for determination of the width of the concrete wall to be poured. This allows for extrusion of these members as well as the corner units which substantially reduces the cost of materials involved and reduces labor by elimination of tie or cross bar placement.
It is therefore an object of the Applicant's invention to provide vertically and horizontally positionable sheet supporting and locating elements which are designed to hold cavity forming sheets in predetermined spaced position to ultimately provide a concrete receiving cavity.
It is a further object of the Applicant's invention to provide a first web having U-shaped channels on the respective sides of the web to afford a bottom and a capping or top member for positioning of sheets of material for forming a concrete receiving cavity.
It is a further object of the Applicant's invention to provide a second web having H-shaped channels on the respective sides of the web which may be utilized in either horizontal of vertical position to receive either edges or ends of sheets of material to form a concrete receiving cavity for forming a poured concrete wall
It is still a further object of the Applicant's invention to provide a corner member to receive the ends of sheets of material and hold the same in spaced relation to one another with each corner including a pair of U-shaped members desired at a desired corner forming angle, each corner requiring a pair of such members which may be joined through either a web or connective elements.
These and other objects and advantages of the Applicant's invention will more fully appear from a consideration of the accompanying description and drawings
