US 5,491,948 A · Tilt-up concrete pad and method of forming and erecting the tilt-up concrete pad

Abstract

The present invention relates to a tilt-up concrete pad and the method or process for forming the tilt-up concrete pad and erecting a building comprised of a series of such tilt-up concrete pads. The precast concrete pad includes reinforcing rebar and embedded angled anchor plates that are secured to the embedded rebar and project therefrom where a portion of the angled anchor plates referred to as weld pads lie flush with the backside of the precast concrete pad. The respective precast concrete pads are placed around a foundation and are connected together by a series of connecting bars that are welded or secured on opposite ends to respective weld pads exposed on the back side of adjacently disposed concrete pads. The present disclosure also shows a work station used for pouring and manufacturing the concrete pads that form the present invention. The work station is designed to support a detachable form and includes a provision for allowing the forks of a forklift to be inserted underneath the poured concrete pad such that the same can removed from the work station. Further, the present invention entails a method of erecting such tilt-up concrete pads and securing them together on a foundation to form a building structure.

Dependent claims

A tilt-up concrete panel comprising:

a) a concrete panel having front and back sides and a surrounding periphery edge structure including top, bottom and side edges and wherein the surrounding periphery edge structure of the panel is substantially formed by concrete;
b) at least one nailer formed and embedded in the concrete panel and extending exposed across a substantial portion of the back side of the concrete panel;
c) reinforcing steel rods embedded within the cast concrete panel;
and
d) a plurality of individual embedded angled anchor plates embedded within the concrete panel in spaced apart relationship and within the confines of the surrounding periphery edge structure of the concrete panel, each angled anchor plate including a leg and a weld pad with the weld pad being disposed at an angle of approximately 90.degree. degrees with respect to the leg, and wherein each leg is secured to a respective steel rod and projects from within the concrete panel toward the back side of the concrete panel and is particularly positioned within the panel such that the angled weld pad lies flush with the back side of the concrete panel such that respective concrete panels can be connected by securing connectors to the weld pads disposed on the back side of adjacently disposed concrete panels.
