Definitions

  • the present invention relates generally to shearwall structures and methods of making a shearwall structure and more specifically to a shearwall enhancement product and method of using the same to construct a shearwall structure.
  • Shearwalls or shearwall structures are essentially walls that have been reinforced and tied down to a foundation or other base structure for the purpose of resisting lateral forces. Shearwall structures are prevalent in high risk seismic and wind zones such as those in California and the southeastern coastal areas and in other geographical areas where there is a probability of earthquakes and/or high winds. Shearwalls are intended to absorb or resist lateral forces applied to a wall panel or section of the wall structure. The ability of a wall panel or section to resist a lateral force is directly related to the dimensions of such wall panel or section. Specifically, increasing the height and decreasing the width of a wall panel or section will reduce the lateral force resistance. Likewise, reducing the height and increasing the width of the wall panel or section will increase the lateral force resistance.
  • the ratio of its height to its width is determined. This ratio is referred to as the “aspect” ratio.
  • the “aspect” ratio for a wall section which is 4 feet wide and 8 feet high would be 2:1, while the aspect ratios for wall sections which are 2 feet wide and 8 feet high or 3 feet wide and 8 feet high would be ratios of 4:1 and 8:3, respectively.
  • shearwalls Two basic types of shearwalls currently exist to resist lateral forces in wall sections.
  • One is a “site built” shearwall in which a wood based sheathing panel is connected to a stud wall section via nails or screws with all of the work done at the building site.
  • the ability of this sheathing panel and its associated stud wall construction to resist lateral forces is a function of the thickness and grade of the sheathing panel, the nail size, pattern and density connecting the wood based panel to the stud structure and the aspect ratio of the wall section.
  • Sheathing panels commonly comprise sheets of plywood, oriented strand board, chipboard and the like.
  • a second type of shearwall is a prefabricated or factory built shearwall in which the entire wall section is prebuilt at the factory to meet certain lateral force resistance specifications. It is estimated that a prefabricated or factory built shearwall can run as much as ten times or more the cost per lineal foot of construction as a “site built” shearwall. Examples of prefabricated shearwall structures disclosed in the prior art are the shearwall structures shown in U.S. Pat. Nos. 5,706,626; 5,729,950 and 6,067,769 in which the structures are formed of metal.
  • Another prefabricated shearwall structure comprises a conventional wood structure in which the edges of a wooden sheathing panel are reinforced by metal strips or channels.
  • the present invention provides a shearwall enhancement product by which the lateral force resistance of a wall section or panel can be significantly increased “on site” by the builder without changing or increasing the thickness of the sheathing panel.
  • the shearwall enhancement product of the present invention includes a plurality of edge sections designed for connection to the peripheral edges of a conventional sheathing panel and a plurality of corner brackets which are designed for connection to the corners of a conventional sheathing panel.
  • each of the edge sections comprises a generally channel shaped configuration defined by inner and outer legs.
  • the outer leg of the channel includes a plurality of nailing holes for receiving fasteners such as nails, screws or the like, with such fasteners extending through both channel legs, through the sheathing panel and into the wooden stud of the wall structure.
  • Each of the corner brackets includes a pair of channel shaped edge sections and a web portion extending between and interconnecting such edge sections.
  • Each corner edge section is provided with a plurality of fastener holes to receive corresponding fasteners which are designed to extend through both legs of such edge sections, through the sheathing panel and into the stud of the wall section.
  • the method of constructing a shearwall in accordance with the present invention includes providing a stud wall structure having a sole plate, a top plate and a plurality of studs extending between the sole plate and the top plate.
  • the method further includes providing a sheathing panel having a plurality of peripheral edge sections and corners at the intersections of adjacent peripheral edge sections and applying a corner bracket to one or more of the corners and a peripheral edge bracket section to one or more of the peripheral edges.
  • such method includes attaching the sheathing panel, with the corner brackets and edge brackets applied, to the stud wall structure with nails, screws or other fasteners or connecting means.
  • the edge brackets and/or the corner brackets are provided with means for retaining the edge and/or corner brackets on the sheathing panel before it is connected with the stud wall structure.
  • this means may include any means that is capable of performing this retaining function such as, but not limited to, inwardly extending protrusions such as dimples or tabs along at least one of the channel legs.
  • a further object of the present invention is to provide a shearwall enhancement product which can be installed “on site” by the builder.
  • a further object of the present invention is to provide a shearwall enhancement product by which the lateral force resistance and stiffness of a wall section can be significantly increased without increasing the thickness of the sheathing panel.

  • the inwardly protruding dimples 66 or other retaining means engage the outer surface of the panel and assist in retaining the edge bracket section to the panel.
  • a length of edge bracket stock 33 may need to be cut to the correct length before application to the sheathing panel.
  • the edge bracket sections should be applied to the entirety of the exposed panel edge between adjacent corner brackets 28 .
  • At least one corner and at least one edge of the sheathing panel is preferable for at least one corner and at least one edge of the sheathing panel to be provided with a respective corner bracket and edge bracket section. More preferably, at least two corners and at least two of the exposed edges should be provided with corner brackets and edge bracket sections and most preferably all four corners and all four exposed edges of the sheathing panel should be provided with corner brackets and edge bracket sections. This is the preferred structure shown in the drawings.
  • Certain shear wall enhancement properties can also be obtained by applying a corner bracket to each corner of a sheathing panel, without using the edge bracket sections or by applying edge bracket sections to less than all of the exposed sheathing panel edges. This is particularly true as the length of the corner bracket edge sections 39 and 40 increases or as the width of the sheathing panel decreases. For example, a sheathing panel which is 32 inches wide and 8 feet high would preferably have a corner bracket 28 at each corner, but an edge bracket section only on its two long exposed edges.
  • the enhanced sheathing panel is positioned onto the outer face of the stud wall structure and connected to such structure by nails or screws or other fasteners through the holes 54 in the corner brackets and the holes 66 in the edge bracket sections.
  • These fasteners extend through the outer legs or leg sections of the corner or edge brackets, through the sheathing panel, through the other legs or leg sections of the corner or edge brackets and then into the corresponding stud wall structure element.
  • For the top edge of the sheathing panel this would be the top plate of the stud wall structure, for the bottom edge of the sheathing panel this would be the sole plate and for the side edges of the sheathing panel, this would be the end posts or other studs.
  • nails or screws are driven through the panel and into such intermediate studs.
  • the preferred application of the present invention is to apply a sheathing panel with the shearwall enhanced hardware (the edge and/or corner brackets) to only one side of the stud wall structure
  • the present invention also contemplates applying a sheathing panel with such shearwall enhancement hardware to both sides of the stud and framing.
