Abstract
A concrete form panel system includes a basic form panel of expanded polystyrene material having at least one slot formed in the top surface along its length, to divide the panel top surface into piers. A series of top hats are provided for selective attachment to the piers to increase the depth of the slots between piers, and thereby increase the depth of a joist formed by hardened concrete poured into the slot. Transverse slots may also be formed by separating top hats along their lengths. The transverse slots create transverse bracing between T-joists in a concrete deck. The form panels and top hats may also be used to create separate structural joists with attachment lifts, to permit connection of the joists to a subsequently constructed floor or deck system.
Claims20
A concrete form system, comprising:
- at least a first elongated flat form panel having flat-top and bottom surfaces, first and second ends, and opposing longitudinal side edges;
- at least a first elongated slot formed in the top surface of the panel and extending from end to end, parallel to the side edges, said slot dividing the top surface of the panel into upstanding piers;
- and
- at least a first elongated flat hat removably secured to a top of each pier, each hat having flat top and bottom surfaces and a width equal to the width of the pier to which it is secured.
A concrete form system, comprising:
- at least a first elongated flat form panel having flat top and bottom surfaces, first and second ends, and opposing longitudinal side edges;
- at least a first elongated slot formed in the top surface of the panel and extending from end to end, parallel to the side edges, said slot dividing the top surface of the panel into upstanding piers;
- each pier having a plurality of hats secured along its length, spaced apart from one another to form transverse slots between the hats on each pier, each hat having flat top and bottom surfaces and a width equal to the width of the pier to which it is secured;
- said panel and hats being formed of expanded polystyrene material;
- and
- said slot being formed with sidewalls that slope outwardly from a top edge to a bottom edge, such that hardened concrete within the slot will prevent the panel from being removed downwardly.
A concrete form system, comprising:
- at least a first elongated flat form panel having flat top and bottom surfaces, first and second ends, and opposing longitudinal side edges;
- at least a first elongated slot formed in the top surface of the panel and extending from end to end, parallel to the side edges, said slot dividing the top surface of the panel into upstanding piers;
- each pier having a plurality of hats secured along its length, spaced apart from one another to form transverse slots between the hats on each pier, each hat having flat top and bottom surfaces and a width equal to the width of the pier to which it is secured.
A concrete form system, comprising:
- at least a first elongated flat form panel having flat top and bottom surfaces, first and second ends, and opposing longitudinal side edges;
- at least a first elongated slot formed in the top surface of the panel and extending from end to end, parallel to the side edges, said slot dividing the top surface of the panel into upstanding piers;
- at least a first elongated flat hat removably secured to each pier, each hat having flat top and bottom surfaces and a width equal to the width of the pier to which it is secured;
- said panel slot having upper edges that are beveled inwardly, and said at least one hat having a depending flange along a longitudinal edge that matches the beveled slot edge to nest in the bevel when secured to the panel pier.
A concrete form system, comprising:
- at least a first elongated flat form panel having flat top and bottom surfaces, first and second ends, and opposing longitudinal side edges;
- at least a first elongated slot formed in the top surface of the panel and extending from end to end, parallel to the side edges, said slot dividing the top surface of the panel into upstanding piers;
- at least a first elongated flat hat removably secured to each pier, each hat having flat top and bottom surfaces and a width equal to the width of the pier to which it is secured;
- and
- at least a second hat secured to the top of the first hat on each pier, the second hat having a length and width equal to the length and width of the first hat.
