Abstract
Description
- 1. Field of the Invention
- An adjustable concrete form hanger to temporarily couple a concrete form used in the pouring of concrete to a structural pier or beam until the concrete has cured at which time the hanger and concrete form are separated from the structural pier.
- 2. Description of Prior Art
- Various structures and methods of temporarily supporting concrete forms have been developed. For example, hangers may be used to straddle to the top flange of beams and connected to forms by bolts or other connectors. One common method is referred to as the needlebeam and consists of a structural steel or timber beam hung from the bottom flange of the outside beam, extending out under the overhanging slab and under the adjacent interior beam for reaction.
- The common method employs a structural steel bracket suspended by a bolt, usually at a 45 degree angle, from a hanger anchored to or installed to straddle the top flange of the exterior beam.
- U.S. Pat. No. 4,660,800 shows a hanger and bracket for supporting form work for steel and concrete during the curing stage of a bridge deck overhang. A hanger attached to the beam of the bridge supports a connector carrying the bracket. The connector is maintained in a substantially vertical position. The bracket is adjustable in both horizontal angle and in grade because of pivotally attached horizontal members, an adjustable compression leg, and connector means. Once the cement is set the bracket is removed for reuse.
- U.S. Pat. No. 3,472,475 describes a bridge overhang bracket, attachable to a flanged girder for supporting concrete forms and catwalks a horizontally aligned support beam the web of the flanged girder. Protruding upwardly from the top of the support beam near abutting end is a cylindrical boss which abuts against a flange of the flanged girder. An inclined dual bolt hanger extends from the clips welded on the girder flange to a stirrup on which the underside of the support beam rests.
- U.S. Pat. No. 5,104,089 shows a concrete supporting bridge overhang bracket system which can be lifted and transferred in gang fashion from a first section of a bridge to a subsequent section. The system includes a series of longitudinally spaced apart laterally extending overhang brackets to which concrete forms are secured. A lift bracket assembly is attachable to a pair of overhang brackets and can be clamped to the deck to support the overhang brackets and the forms from the deck so that the brackets can be disconnected from the deck. Once disassembled, the lift bracket assembly can be supported by a crane and unclamped from the deck, the crane thereafter moving the lift bracket assembly, the overhang brackets and the forms to the subsequent section.
- U.S. Pat. No. 3,806,074 relates to forms for molding concrete on horizontal I-beams. The forms are adjustable from a position above the beams. With respect to the interior space between two beams, clips and/or hangers suspend bolts adjacent the beams, the bolts being threadably engaged with brackets between which extends a joist located below and in overlapping relation with the upper flanges of the beams. The bolts are rotatable from a position atop the beams to adjust the brackets to control the locating of the joist. Sheeting supported on the joist support a mold for wet concrete.
- U.S. Pat. No. 5,092,559 teaches a concrete form support assembly for forms used to pour concrete for bridge floors. Such forms include a plywood flooring supported at a desired uniform depth relative to the plane of the upper surface of the bridge beams. The plywood flooring is supported by ledgers which extend laterally between the bridge beams and stringers on the top thereof which extend longitudinally and parallel with the bridge beams. The ledgers are supported by vertical bolts hanging from hanger bars on each side of each bridge beam, with support plates at the lower end of the vertical bolts to support opposite ends of the ledgers, and threaded nuts below the support plates to adjust the plates and ledgers thereon up and down. After the plywood flooring has been put in place, workmen cannot thereafter reach the adjusting nuts from above to make final depth adjustments of the flooring. The support assembly in accordance with the present invention provides depth adjustable hanger bolts adjustable from above the plywood flooring after it has been put in place.
- U.S. Pat. No. 5,524,854 shows a structural supporting system for the use as a temporary support in concrete overhang construction and for the use as a support in concrete slab truss construction. The structural supporting system includes a series of support beams and a plurality of support brackets positioned along the length of the support beam. A support bracket is provided at the opposite ends of the support beam for the suspended support of the support bracket to increase or reduce the span of the support beams. A series of cooperating brackets are positioned intermediate the support brackets to support of one support bracket in the concrete overhang falsework construction. A series of cooperating brackets are positioned intermediate to the support brackets for the support of two support brackets in the concrete slab falsework truss construction. The support bracket or brackets include adjustable upper and lower opposing gripping surfaces for engaging corresponding upper and lower surfaces of the support beam in adjustable mounting relationship thereto. The brackets include an integral attachment pin to secure the support beams to the support bracket for attachment of the support bracket to a fastener suspended from the concrete overhang form construction and the concrete slab falsework truss construction.
- U.S. Pat. No. 6,273,393 shows a concrete form support bracket assembly used to pour concrete bridge decks or building floors. The brackets, which are used in pairs, have a base plate to bear the weight of form ledgers, a rear wall extending from the base plate, and a pair of spaced apart side walls extending from the rear wall and base plate. A fastener is provided for securing the ledger in the bracket and an opening is located in the base plate for providing a bolt to support and adjust the bracket. In the assembly form, the bracket may include a hanger bar, receiving channel and adjustable bolt as a support for the bracket.
