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

This patent describes a new system for securely anchoring veneer panels to a backup wall. The system includes a metal strap that can be easily attached to the anchor and securely rotated in place to securely attach the veneer panel to the anchor. The strap has a slot for easy installation and contains a securement notch for easy attachment to the wall. The strap is designed to withstand seismic and shear force requirements. The system is economical and easy to install, and includes labor-saving devices to simplify the installation process. Overall, the system is a reliable and efficient means for securely anchoring veneer panels 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.
