WALL REINFORCEMENT SYSTEM AND METHOD
A reinforcement system for a wall includes a bracket secured to a support disposed above the wall with a plurality of fasteners. A strap is engaged with the bracket and is adhered to the wall for reinforcing the wall.
This application is a continuation of U.S. patent application Ser. No. 12/212,151, filed on Sep. 17, 2008, which claims the benefit of U.S. Provisional Application No. 60/973,299, filed on Sep. 18, 2007. The entire disclosures of the above-listed applications are incorporated herein by reference.
FIELDThe present disclosure relates to a system and method for reinforcing structural elements. In particular, the present disclosure relates to a system and method for wall reinforcement including an anchor system for coupling walls and support members.
BACKGROUNDThe statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
A variety of walls and other structural elements are known to be generally capable of supporting residential and light commercial structures. Over time, however, such walls and structural elements can crack, tilt, bow, or otherwise deform due to inherent weaknesses attributable to particular structural characteristics thereof.
For example, walls constructed of concrete blocks have excellent compressive strength to support structures placed upon them. However, these walls are inherently weak with respect to lateral loads and are particularly susceptible to cracking from water pressure, as the mortar joints at which these walls are connected are weak in tension and tend to separate relatively easily when subjected to tensile forces.
Deformation, such as cracking, tilting, and bowing, if left untreated, can become progressively greater and eventually facilitate collapse of an entire structural element with resultant damage to the structure supported thereon. While several methods are known for treating such deformation (e.g., it is known to adhere a carbon fiber material to a structural element, such as described in U.S. Pat. Nos. 6,746,741; 6,846,537; and 6,692,595), it would be desirable for a relatively simple and cost effective system and method for coupling a structural element to a separate support (e.g., a floor joist or other beam) in order to treat, prevent, or otherwise inhibit deformation of the structural element.
SUMMARYThe present disclosure provides a reinforcement system for a structural element. The reinforcement system includes a bracket secured to a support with a plurality of fasteners, a strap engaged with the bracket and disposed on the structural element, an adhesive material disposed on the structural element for securing the strap to the structural element, and a laminate for covering the assembly.
The present disclosure also includes a method for reinforcing a structural element. The method includes securing a bracket to a support proximate the structural element, engaging the bracket with a strap, securing the strap to the structural element with an adhesive, and covering the assembly with a laminate.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustration purposes only and are not intended to limit the scope of the present disclosure in any way.
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
Referring to
Bracket 22 is a relatively rigid component and can be made from a variety of materials. By way of non-limiting example, bracket 22 can be made of 60/61 T-6 aluminum with a 3/16″ structural T hard anodized coating. As best shown in
Strap 26 is a flexible material with a relatively large tensile strength. For example, strap 26 can be made of an aramid composite fabric webbing which includes Kevlar® or other materials. Strap 26 can include a center portion 40 which is traditional fabric and ends 42, 44 which are pre-impregnated with adhesive and pre-cured in order to facilitate securing of strap 26 to a structural element as described in fuller detail herein. Prior to installation, ends 42, 44 can be covered/protected with peels 46, 48. Peels 46, 48 can have a textured surface that creates a roughened surface in the adhesive that is cured on ends 42, 44 of strap 26. The roughened surface helps to facilitate bonding with the adhesive.
