Benefits of technology

The invention is a device that allows contractors to properly block and frame openings in a plywood shear panel diaphragm with a single piece of material that ensures proper placement and quality. The device is designed to securely hold the loads specified by architects or engineers without requiring additional wood and block placements by workers. The device can be easily selected from stock with different shear load resisting capabilities, and can be mass-produced. It can also be combined with other devices to facilitate proper construction and assembly. Overall, the device helps ensure the proper placement of blockages in a way that protects against shear loads.

Problems solved by technology

As detailed, this current method is fraught with potential damaging issues which subject the building to stresses not planned for.

Embodiment Construction

[0029]This invention as disclosed in the drawings has the principle use in the construction environment but there exists no limiting language to prevent this invention to be practiced in other fields of use. The invention consists of two main elements, a blocking section and a retention section. This invention is detailed with the use of the invention in the creating of shear panels in new or existing wood framed construction but its use is not limited to only construction industry usage as disclosed by its best mode disclosure by this application.

[0030]FIG. 1 details the front view of the apparatus 100 where exterior portion 2 of strap 1 is bounded by proximal end 10 and distal end 9 with top edge 8 and lower edge 8A. Distal end 9 contains header attachment means 28. The strap 1 has two principle functional areas; a blocking section 1B and a header section 1A. The strap is constructed using metallic compounds, usually steel or aluminum. It is foreseen that other materials can be us...

Abstract

Plywood shear panel diaphragms are utilized in building walls and roofs to support against lateral forces such as earthquakes, wind, tornadoes, and hurricanes. Plywood is typically used for the shear diaphragm in wood construction, nailed vertical or horizontal to wood members. When introducing an opening in a plywood shear panel diaphragm, the diaphragm becomes weakened. Shear transfer process is required to maintain integrity in the shear diaphragm at the opening. The strength from the diaphragm is transferred to the openings edges, the top and bottom edges, using blocks between the framing members acting in compression, and the strap, which acts in tension, transfers the support of the diaphragm to opening. When compared to conventional means, the Block Strap apparatus is a better, more accurate, predictable, cost cutting, labor reducing product for providing for shear transfer requirements in typical common wood construction.

Description

CROSS REFERENCE TO PENDING APPLICATIONS[0001]This application claims benefit of prior filed co-pending provisional application No. 62 / 467,508 entitled “Block Strap” is a manufactured integral two component single piece of metal hardware that provides blocking and strapping for shear transfer support to an opening from a vertical or horizontal plywood shear panel diaphragm in a wood framed wall or roof” filed on Mar. 6, 2017 in the name of Daniel Lester Varnum of Moorpark, Calif., said provisional application being hereby incorporated by reference as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]The purpose of this invention is to reduce labor, material costs, in the framing of buildings. Current methods are labor intensive and can be prone to errors in installation causing a reduction in the shear strength of the framing and or possible failure. Also, one of the major causes of cracking or sagging around windows and doors is from movement in the wall, which causes the w...
