Abstract
A metal "U" shape channel form is used to form a concrete beam, and has two laterally opposed outwardly extending horizontally disposed flanges with two supporting areas arranged in a stepped fashion for selectively supporting a metal deck or both a metal deck and plywood between the span of adjacently arranged channel forms used to form a slab therebetween, which slab may be composite in that the formed slab integrally includes a metal deck. A "U" shape shoring head of complementary shape to the channel form is mounted on a shoring frame to hold the channel form in place for the pouring of the concrete, and a shoring head can be used with a structural member arranged to support the metal deck of variable spans for slabs of variable dimensions in the available space.
Claims17
In a slab-beam formwork system for receiving poured concrete in the constructing of a roof or floor, comprising:
- a generally U-shape channel form adapted to form a concrete beam for said system and having an outwardly extending support means extending generally in a horizontal plane and being part of at least one sidewall of said channel form adjacent an opening for said receiving of said poured concrete,
- said support means consisting of at least two generally horizontal support areas, one said area being on an upper elevational level in close proximity to said opening of said channel form and the other of said area being on a lower elevational level remote from said opening of said channel form,
- each of said areas adapted to support a structural member for the forming of said slab, and said areas having means adapted to alternately support said structional member in the pouring of said concrete whereby said structural member is positionable on said one area on said upper elevational level to become a composite part of said slab, or said structural member is positionable on said other area on said lower elevational level to be removed after the forming of said slab.
A method of forming a concrete slab-beam system for a roof or floor with a formwork, the steps comprising:
- providing a generally U-shape channel form with an opening for receiving concrete and having outwardly extending flange means with at least two supporting surfaces with one surface in an upper elevational level and adjacent to said opening, and another surface in a lower elevational level away from said opening and
- in the step for forming a composite slab consisting of a metal deck integrally cast with said concrete, positioning said metal deck onto said one surface in said upper elevational level of cooperative flange units of two neighboring cooperative channel forms.
A method of forming a concrete slab-beam system for a roof or floor with a formwork, the steps comprising:
- providing a generally U-shape channel form for forming said beam, and having an opening for receiving concrete and outwardly extending flange means having at least two supporting surfaces with one surface in an upper elevational level adjacent to said opening, and another surface in a lower elevational level away from said opening, and
- in the step for forming a concrete slab, positioning a support member which is to be removed onto said one surface in said upper elevational level of cooperative flange means on two neighboring cooperative channel forms.
A beam form for receiving poured materials such as concrete or the like to form a beam upon solidification of said material, comprising:
- a generally U-shape unitary metal channel with a bottom wall and two opposing sidewalls extending upwardly and outwardly from said bottom wall to form an opening for said receiving of said material,
- stepped flange means associated with at least one said sidewall generally laterally disposed relative thereto and consisting of at least two supporting surfaces, one of said two surfaces of said flange means being on an upper elevational level in close proximity to said opening and the other of said surfaces being on a lower elevational level remote from said opening of said channel, each of said surfaces having means adapted to horizontally and alternately support a member whereby said member either becomes an extension of said formed beam upon said member being supported on said one of said two surfaces, or said member is removable with said beam form after the forming of said beam.
