Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. provisional application No. 61/579,021 filed Dec. 22, 2011, which is herein incorporated by reference in its entirety.

BACKGROUND

1. Field of the Invention
The present invention relates to clip anchor connectors for building construction.
2. Background of the Art
Many buildings have a basic structure of brick, blocks or concrete sheathed by panels or some form of facing product that can make them look more attractive, as well as adding to the insulation and weather proofing. However, the attachment of such facing product needs to be secure and long-standing.
Typically, facing product can include terra cotta, clay, ceramic or glass fiber reinforced cement elements. Up until today the facing product elements were attached to concrete precast or glass fiber reinforced concrete (“GFRC”) precast by using adhesive or by pouring concrete on the back of the elements and allowing the concrete to cure.
Referring to FIG. 1, a prior art system is shown wherein terra cotta tiles T are attached to a concrete wall C by a layer of mortar M.

SUMMARY OF THE INVENTION

A system for attaching a facing product to a concrete substrate comprising a facing product having a front face and a back surface, the facing product being configured with at least one convexity, recess or opening adapted to receive a clip anchor connector; and at least one clip anchor connector having an anchoring portion for embedding in the concrete substrate, a spine, and an engagement portion configured and dimensioned to engage the convexity, recess or opening in the facing product. The spine is longitudinal and has a first end and opposite thereto a second end. The anchoring portion of the clip is shaped so as to be fixedly embedded in the concrete substrate and prevent separation of the clip connector therefrom, and is positioned at one of said first and second ends. The engagement portion is positioned at the end of the spine opposite that of the anchoring portion and has at least one, and preferably two laterally extending wings configured to engage a convexity, recess or opening in the facing product.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S)

The purpose of this invention is to provide a better and safer precast/GFRC facing product system by using a clip anchor connector in which on one side holds in place the terra cotta/clay/ceramic/glass fiber reinforced cement facing product element and on the other side act as an anchor into the concrete/precast.
The clip anchor connector can be made from break metal or extruded metal or any other material. It can be inserted from the end of the terra cotta, clay, ceramic, or glass reinforced cement facing product elements, or it can be inserted at the middle and turned 90 degrees to be set at the final location.
Referring now to FIG. 2, a construction mounting system for anchoring a facing product 102 to a concrete substrate 101 is shown. A clip 110 is affixed to the facing product 102 and has a Y-shaped base which is embedded in the concrete substrate 101.
Referring now to FIG. 3, a clip anchor connector 110 is shown attached to a terra cotta tile 102. The tile 102 has a front surface 102 a and a back surface 102 b. The back surface includes a plurality of convexities 104 spaced apart by recesses 108. The convexities 104 each include a flat surface 104 a, sloped opposite sides 104 b, and ledges 104 c. The flat surface 104 a has a width which is narrower than the width of the convexity at the ledge portion 104 c.
The clip anchor connector 110 includes a longitudinal, vertical (as shown) spine 111 having first and second opposite end portions. At one end portion a Y-shaped anchor portion 112 is configured to have two legs 112 a and 112 b angularly extending from the end of the spine 111. The anchor portion 112 is adapted to be embedded in a concrete wall. At the other end of the spine portion 111 an engagement portion includes two laterally and oppositely extending wings 113 each having a horizontal (as shown) portion 114, an angled portion 116 and a hook portion 118, wherein the horizontal portion 114 and angled portion 116 are connected at bend 115, and the angled portion and the hook 118 are connected at bend 117. The wings 113 are configured to engage convexity 104 such that horizontal portion 114 of the clip abuts flat surface 104 a, angled portions 116 abut respective sloped sides 104 b, and the hook portions 118 engage ledges 104 c so as to inhibit disengagement of the clip anchor connector from the tile 102.
The clip anchor connector 110, as well as the embodiments of the clip anchor connectors described below, is preferably fabricated as a single piece member from a suitable metal (e.g., ferrous or non ferrous metals such as stainless steel, bronze, aluminum, etc.). Optionally, the single piece metal can be a resilient metal strip of spring steel which is folded upon itself to provide the configuration shown in the drawings so that it can be laterally expanded to facilitate engagement of the wings 113 with the convexity 104. Alternatively, the convexities can be linearly configured and the clip anchor connector 110 can be slid onto the convexity at the edge of the tile and linearly moved to a desired location along the convexity.
