AI Technical Summary

Benefits of technology

The invention is preformed wire spacers that are designed to hold a grout tube in place within a concrete form. These spacers are made from a continuous length of spring steel that is shaped to fit around the grout tube. The spacers have hooks on their ends, allowing them to be easily attached to the grout tube. The central portion of the spacer can be temporarily expanded in size by grasping the free ends and applying force, making it easy to combine with the grout tube. Multiple spacers are used on a single tube to provide proper support and positioning of the tube. Overall, the wireless spacer system simplifies the process of installing grout tubes in concrete forms.

Problems solved by technology

Masonry structures and the mortar holding them together have similar properties to concrete and also have a limited ability to carry tensile loads.
This is a time consuming and expensive process.

Embodiment Construction

[0015]FIGS. 1, 2 and 3 show the preferred embodiment of the invention. A spacer 20 comprises a central portion 22 and a pair of free ends 24. The free ends 24, 26 extend outwardly from the central portion 22. Preferably the free ends 24, 26 extend in opposite directions and are one-hundred eighty degrees apart. The spacer 20 is formed from a single continuous length of spring steel wire.

[0016]In the preferred embodiment, the central portion 22 transitions to the free ends 24, 26 at an angle. Additionally, the angle designated as A in FIG. 1 is preferably between 60 and 90 degrees, with 75 degrees being shown in FIG. 1. The angle A can have an effect on the force needed to expand the central portion 22 as further discussed below.

[0017]Free end 24 has a fastener 27 which is preferably a hook 28 formed at its outer end 29 while free end 26 has a fastener 31 again preferably a hook 32, and a handle 34 at its outer end 35. The hooks 28, 32 engage a frame 40 of a future concrete structure...

Abstract

A spacer for securing a grout tube to a frame prior to the pouring of concrete to form a concrete structure. The spacer comprises a central portion and two free ends extending from the central portion. The central portion surrounds at least a portion of the grout tube and the free ends are fastened in some fashion to the frame. A plurality of spacers can be utilized for securing the grout tube in place. The central portion is preferably circular and the manipulation of the free ends can expand or contract the diameter of the central portion.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to provisional patent application 61 / 588,271 which was filed on Jan. 19, 2012, and is hereby expressly incorporated by reference.BACKGROUND OF THE INVENTION[0002]There are numerous concrete products used in the construction industry in a variety of applications, such as foundations for supporting structures, as bridge and deck panels, and as beams for structures, just to name a few. Concrete is a material that is very strong in compression but relatively weak in tension. Masonry structures and the mortar holding them together have similar properties to concrete and also have a limited ability to carry tensile loads.[0003]In order to compensate for this imbalance in the behavior of concrete and masonry structures, reinforcement bars, which are common steel bars, are typically used as a tensioning device to produce reinforced concrete and reinforced masonry structures. These reinforcement bars, common...
