Stay-In-Place Forms and Methods and Equipment for Installation Thereof

Abstract

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

1 . We claim a form for creation of a structure, the form for supporting uncured concrete prior to curing comprising:
 a substantially vertical component, said substantially vertical component having a substantially vertical inwardly facing   surface and a substantially vertical outwardly facing surface;
 a substantially horizontal component having a substantially 
 horizontal inwardly facing surface and a substantially horizontal 
 outwardly facing surface, said substantially vertical component 
 located substantially perpendicular to said substantially horizontal
 component and extending upwardly from said horizontal component, the substantially vertical component and the substantially horizontal component forming an L shape; 
 
 at least one insert in or through at least one of the group consisting of the 
 substantially vertical inwardly facing surface, the substantially 
   horizontal inwardly facing surface; and combinations thereof;
 a rabbet extending longitudinally along the substantially horizontal
 component, the rabbet recessed in said substantially horizontal 
 outwardly facing surface at the distal end thereof, the rabbet defined 
 by top and side surfaces, the side surface being substantially vertical, 
 and the top surface located at an angle of greater than ninety degrees 
 relative to the side surface, the top surface tapered upwardly as it 
 extends away from the side surface.
