Backup wall reinforcement with t-type siderail

Abstract

A backup wall reinforcement with T-type siderail anchoring system is described for use in masonry cavity walls. The reinforcement and integral anchor is hybrid device installed within the backup wall and interlocked with novel veneer ties. The novel veneer ties are manually connected through swinging or twisting the veneer ties until the veneer ties are interlocked with the anchor. Once interlocked, lateral and vertical veneer tie movement is limited strengthening the cavity wall structure. The inclusion of a reinforcement wire within the veneer ties and the exterior wall provides a seismic structure.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to reinforcement and anchor assemblies for use in masonry backup walls and, in particular, cavity wall constructs with backup and veneer walls that require superior anchoring properties. The backup wall reinforcement is a hybrid anchoring system which includes a reinforcement with an integrated anchor for connection to an interlocking veneer tie which provides a 3-axis restraint system, limiting movement and exterior wall displacement.[0003]2. Description of the Prior Art[0004]Masonry, the building of structures from individual units laid in and bound together by mortar, is commonly used for the construction of buildings. Such widespread use is the result of the high durability, compressive strength, thermal mass and heat resistance of the masonry building materials. Because masonry construction requires extensive manual labor and individual building materials, the quality of the masonry construct...

AI Technical Summary

Benefits of technology

[0021]An alternative veneer tie or veneer anchor is a metal stamping designed to connect with and be secured over the anchor and within the exterior wall bed joint. The alternative veneer tie contains a slot in the connector portion that is dimensioned to allow the veneer tie to be placed over the anchor and manually rotated or twisted 90 degrees for securement on the anchor. The veneer tie optionally contains a securement notch that snap fits onto the wall anchor. Upon securement on the anchor, the free end of the veneer tie spans the cavity and inserted within the bed joint of the exterior wall. For greater seismic protection, the veneer tie is notched to secure a reinforcement wire within the veneer tie and the bed joint of the exterior wall. For greater displacement protection, the veneer tie section that spans the cavity is offset where the tie section abuts the interior of the exterior wall.

[0024]It is a further object of the present invention to provide an anchoring system comprising a limited number of component parts that are economical of manufacture resulting in a low unit cost.

[0025]It is yet another object of the present invention to provide an anchoring system which is easy to install and meets seismic and shear resistance requirements.

[0026]It is another object of the present invention to provide labor-saving devices to simplify seismic-type installations of brick and stone veneer and the securement thereof to a backup wall.

Problems solved by technology

Besides earthquake protection, the failure of several high-rise buildings to withstand wind and other lateral forces has resulted in the incorporation of a requirement for continuous wire reinforcement in the Uniform Building Code provisions.

However, none of these devices offers a hybrid backup wall reinforcement and anchor that when combined with the disclosed veneer tie provides reinforcement and 3-axis displacement protection.

Limiting veneer tie movement protects against movement and shifting of the exterior wall, which is a cause of structural damage.

Accordingly, while several distinct devices were developed to provide a connection between the backup and exterior walls, the current state of the art does not fulfill the need for a hybrid anchor and reinforcement assembly that provides a 3-axis restraint system.
