Abstract

Abstract A side weld plate for joining adjacent concrete slabs together by welding. An elongated body is provided having a body section for embedment in a concrete slab and a flange section for positioning adjacent an edge of the concrete slab. The flange surface provides upon embedment of the body section in the concrete slab, an exposed weld surface which allows for adjacent concrete slabs also having a side weld plate to be welded together.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 242 words
A concrete structural element for attachment to an adjacent surface, the concrete structural element comprising: a concrete slab having a pair of opposing planar faces being generally parallel to one another and at least one attachment side edge, at least a portion of the length of said side edge defining an acute angle with respect to one of said planar faces; at least one side well plate partially embedded in said concrete slab, said weld plate comprising a generally planar body section disposed generally parallel between said opposing planar faces of said slab, said body section defining at least one opening therein with said concrete slab located totally around at least three sides of said body section, and a flange section integral with and adjacent an outer edge of said body section, said flange section extending upwardly from said body section generally at said acute angle relative to said body section, an inner surface of said flange section extending upwardly at said acute angle in substantially continuous contact with said side edge of said concrete slab, and an outer surface opposite said inner surface extending upwardly at said acute angle for being at least partially exposed for attachment to an adjacent surface, whereby when said side weld plate of the concrete structural element is positioned adjacent a surface to be attached to said concrete structural element, a generally V-shaped space is defined therebetween for receipt of an element therein for welding thereto.
Claim 2
Dependent Claim 242 words
A concrete structural element for attachment to an adjacent surface, the concrete structural element comprising: a concrete slab having a pair of opposing planar faces being generally parallel to one another and at least one attachment side edge, at least a portion of the length of said side edge defining an acute angle with respect to one of said planar faces; at least one side well plate partially embedded in said concrete slab, said weld plate comprising a generally planar body section disposed generally parallel between said opposing planar faces of said slab, said body section defining at least one opening therein with said concrete slab located totally around at least three sides of said body section, and a flange section integral with and adjacent an outer edge of said body section, said flange section extending upwardly from said body section generally at said acute angle relative to said body section, an inner surface of said flange section extending upwardly at said acute angle in substantially continuous contact with said side edge of said concrete slab, and an outer surface opposite said inner surface extending upwardly at said acute angle for being at least partially exposed for attachment to an adjacent surface, whereby when said side weld plate of the concrete structural element is positioned adjacent a surface to be attached to said concrete structural element, a generally V-shaped space is defined therebetween for receipt of an element therein for welding thereto.
Claim 3
Dependent Claim 25 words
The concrete structural element as defined in claim 1, wherein said weld plate is steel, and is suitable for being welded to said adjacent surface.
Claim 4
Dependent Claim 16 words
The concrete structural element as defined in claim 1, wherein said opening is rectangular in shape.
Claim 5
Dependent Claim 34 words
The concrete structural element as defined in claim 1, wherein said angle is in a range of from about 20 to about 35 degrees with respect to a plane perpendicular to said body section.
Claim 6
Dependent Claim 23 words
A concrete structural element as defined in claim 1, wherein said body section of said side weld plate is substantially rectangular in shape.
Claim 7
Dependent Claim 23 words
A concrete structural element as defined in claim 1, wherein said flange section of said side weld plate is substantially rectangular in shape.
Claim 8
Dependent Claim 31 words
A concrete structural element as defined in claim 1, wherein said opening in said body section of said side weld plate is rectangular and is totally surrounded by said body section.
Claim 9
Dependent Claim 27 words
A concrete structural element as defined in claim 7, wherein said body section of said side weld plate defines further smaller openings located around said rectangular opening.
Claim 10
Dependent Claim 29 words
A concrete structural element as defined in claim 1, wherein said flange section of said side weld plate is generally planar and smaller than said generally planar body section.
Claim 11
Dependent Claim 53 words
A concrete structural element as defined in claim 6, wherein said generally planar body section of said side weld plate is elongated and the length thereof from said outer edge adjacent said integral flange section to a side edge thereof opposite said flange section is greater than the thickness of said concrete slab.
