Abstract
A modular edge form system for cast in place suspended concrete slabs, comprising wood or metal edge forms that close gaps between joists when a row of joists is above vertical supporting structures. The edge forms may depend on joists directly, or by means of wood edge form support structures; the joists in turn depend on joist hangers. Areas in front of the butt ends of joists are covered by means comprising the use of notch cover plates and/or bendable notch cover rectangles. The edge form system contains and supports cast-in-place horizontal concrete structures when they are poured and while they cure.
Claims16
A modular edge form system for cast in place suspended concrete slabs, comprising:
- a. metal edge forms, having a front face, a top flange which depends on a joist, one or more notches and/or side half notches sized to the outer width of a joist hanger, one or more upper notch covers and/or half notch covers, and one or more bottom reinforcing flange sections between the notches, and
- b. a series of sized notch cover plates having faces wider than the metal edge form notches and/or adjoining half-notches, and having a range of heights such that the height increments are equal to or less than the height of the said upper notch covers and/or half notch covers of the said metal edge forms, and having tongues that are inserted between the butt end of a joist and the inner central wall of a joist hanger depending on a vertically supporting structure, such that the sized notch cover plates hold the said metal edge forms against the edge of the said vertically supporting structure, and
- c. top sheathing placed on top of the joists and on the metal edge form top flanges, and dimensioned such that the edge of the sheathing aligns with the front face of the metal edge forms.
A modular edge form system for cast in place suspended concrete slabs, comprising:
- a. wood edge forms, comprising a front face and upper support structures on each side, and
- b. top wood edge form support structures, comprising a front face, and further comprising wood edge form upper support housings on each side which engage with and support the wood edge form upper support structures, and further comprising a top plate which depends on a joist, and
- c. the joist depending on a joist hanger, the said joist hanger in turn depending on a vertically supporting structure, and
- d. top sheathing placed on top of the joists and on the wood edge forms, and dimensioned such that the edge of the sheathing aligns with the front face of the wood edge forms.
