Connecting tie for metal concrete pouring forms

Abstract

A connecting tie for use with a metal concrete pouring form. The tie includes an elongated flat bar adapted for attachment at each end to a metal pouring form to hold two forms in a spaced apart and parallel relationship thereby forming a concrete receiving cavity therebetween. A resilient seal is disposed transversely across each side of the bar adjacent each end of the bar in order to seal the tie to the metal forms.

Description

BACKGROUND OF THE INVENTION[0001]I. Field of the Invention[0002]The present invention relates generally to concrete pouring forms and, more particularly, to a connecting tie for use with metal pouring forms.[0003]II. Description of Related Art[0004]There are many previously known panel systems for forming poured concrete walls, floors and ceilings, hereinafter collectively referred to as walls. Furthermore, a number of these previously known systems utilize reusable aluminum panels.[0005]In these previously known aluminum panel systems, the panels are generally rectangular in shape having a top, bottom and two spaced apart sides. At least two panels are positioned in a spaced apart relationship relative to each other and form a concrete receiving cavity therebetween. Consequently, after the entire panel system has been erected in the shape of a desired poured concrete wall, the concrete is poured into the cavity and allowed to set. Thereafter, the aluminum panels are removed from th...

Benefits of technology

[0014]In practice, with the connecting tie positioned between two adjacent panels, the resilient seal fills and therefore closes any gap that may be present between the connecting tie and the two adjacent panels entrapping the end of the tie. This resilient seal thus simply, but effectively, prevents concrete cream from entering into the notches between adjacent panels during the concrete pour.

[0015]In most cases, connecting ties are positioned in several, but not all, of the notches between adjacent panels in preparation for the concrete pour. In order to prevent the concrete cream from entering into the unused facing notches between adjacent panels, the present invention further provides a spacer which is positioned within the unused notch. This spacer, furthermore, includes a fluid seal along at least one side which fluidly seals the spacer to the panel and prevents the concrete cream from entering into the notch containing the spacer during the concrete pour.

Problems solved by technology

One disadvantage of these previously known metal or aluminum pouring form systems is that the connecting ties have a thickness typically somewhat less than the thickness of the facing notches between the adjacent panel forms so that small spaces are open around the connecting ties.

However, the hardened cream contained within the notches diminishes the overall depth of the notches so that, when a connecting tie is positioned within the notches, the connecting tie effectively separates adjacent panels from each other by a small yet unacceptable distance.

Such a procedure, however, is not only time consuming, labor intensive and therefore expensive, but also may result in damage to the metal form.
