Benefits of technology

"The present invention is a device used in construction to hold a weldment plate in place during the curing of concrete. The device includes a spacer support that engages the surface on which the concrete is poured and a weldment plate that holds the support in position. The spacer support is attached to the weldment plate using a cup-shaped portion and can slide on top of the support. The device is made of plastic, metal, or powdered metal, and can be adjusted in length by scoring the surface or cutting it in the field. The technical effects of the device include improved stability and weight bearing capacity during construction, as well as reduced surface treatment requirements for the finished wall."

Problems solved by technology

Since these steel plates are denser than the wet concrete, they tend to sink below the surface.
Neither of these current practices provides effective quality control and the results often are not those desired.

Embodiment Construction

[0013] The present invention is a weldment plate spacer support or stud extender, which is generally depicted in FIGS. 1-3, and is generally represented by the numeral 10. The stud extender comprises an elongated body portion 22 having a top planar portion 28, a surface engaging portion 24, and means 26 for attaching the spacer support to weldment plate 11. In this embodiment, weldment plate 11 includes projections 15 which may take the form of Nelson studs welded to the surface 13 of weldment plate 11 to be embedded in the concrete 17. Body portion 22 is of a length substantially equal to the thickness “t” of the concrete wall 18 minus a dimension of the weldment plate 11 extending in a direction of the thickness of the concrete wall 18. In this case, the dimension of the weldment plate extending in the direction of the thickness of wall 18 includes the thickness of plate 12 as well as the length of Nelson stud 15. Nelson studs come in a plurality of sizes and lengths. Common diame...

Abstract

A spacer support or stud extender having a body portion, a surface engaging portion and a securement to attach the body portion to a weldment plate in tilt-up construction wherein the extender is coupled to a head of a stud depending from a weldment plate with a cup-shaped engaging portion.

Description

RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 964,143 filed Oct. 13, 2004, which is a divisional of U.S. patent application Ser. No. 10 / 272,698 filed Oct. 16, 2002, now U.S. Pat. No. 6,820,390 dated Nov. 23, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 09 / 777,400 filed Feb. 6, 2001, now U.S. Pat. No. 6,823,635 dated Nov. 30, 2004.FIELD OF THE INVENTION [0002] The present invention relates to the manufacture of concrete walls used in tilt-up construction. More particularly, the present invention is directed to a spacer support that holds a weldment plate in proper position until the wet concrete sets up. BACKGROUND OF THE INVENTION [0003] In commercial construction, as well as in residential construction where wood is at a premium, builders are increasingly using tilt-up construction, that is, they are pouring concrete walls in forms as they lay on the ground, floor or other surface, and then...
