Abstract
A shear wall system comprises stucco fasteners consisting of an elongated first portion that is driven into a wood frame wall, and an elongated second portion that is completely embedded in a stucco wall panel. In one embodiment, the fasteners consist of an assembly having a first element that is driven into the wood frame wall, and a second annular element receiving a portion of the first element and that is embedded rigidly into the cement stucco wall. Ductile movement of the fastener components with respect to wood frame wall and the stucco wall provides energy dissipation.
Claims28
A stucco wall construction comprising:
- a wood frame;
- stucco lath secured to said wood frame by a plurality of first fasteners;
- a plurality of second fasteners, each comprising an elongated first portion embedded in said wood frame and an elongated second portion not embedded in said wood frame, said second portion including an upper end spaced from the surface of said wood frame, a lower end bearing against said wood frame and a narrowed middle portion between the fist and second ends, said elongated first portion spaced apart from an inner surface of said lower end by a clearance;
- and,
- stucco applied to said stucco lath so as to substantially embed said second portion in said stucco,
- wherein said upper end is integrally formed with said first portion.
A fastener assembly for use in a stucco wall construction comprising a first element having an elongated portion and a head portion, said elongated portion having a substantially uniform cross section along its length, and a second element having an aperture for receiving said first element therethrough, whereby to maintain said head of said first element in a predetermined spaced relationship to a surface in which said first element is embedded, said second element comprises an upper end having a surface that tapers inward toward a middle portion of said second element.
A stucco wall construction comprising a wood frame, stucco lath secured to said wood frame by a plurality of first fasteners, a plurality of second fasteners embedded in said wood, said second fasteners comprising a fastener assembly having a first element having an elongated portion and a head portion, said elongated portion having a substantially uniform cross section along its length, and a second element having a passageway for receiving said first element therethrough, whereby to maintain said head of said first element in a predetermined spaced relationship to a surface in which said first element is embedded, said second element has an upper end and a lower end, and wherein said second element encloses the head of said first element in said upper end so as to restrain it from extending upward through the upper end of said passageway.
A fastener assembly for use in a stucco wall construction comprising a first element having an elongated portion and a head portion, said elongated portion having a substantially uniform cross-section along its length, and a second element having a passageway for receiving said first element therethrough, whereby to maintain said head of said first element in a predetermined spaced relationship to a surface in which said first element is embedded, said second element having an upper end and a lower end, and wherein said second element encloses the head of said first element in said upper end so as to restrain it from relative upward axial movement.
A method of applying stucco on the wood frame of a building wall comprising the steps of:
- securing stucco lath to said wood frame with a plurality of first fasteners;
- embedding in said wood frame a plurality of second fasteners, said second fasteners comprising an elongated first portion embedded in said wood frame and a second portion not embedded in said wood frame, said second portion including a first head spaced from the surface of said wood frame a second head bearing against said wood frame and a narrowed middle portion between the first and second heads, said elongated first portion separated from an inner surface of said second head by a clearance;
- and,
- applying stucco to said stucco lath so as to substantially embed said first and second heads of said second fasteners in said stucco,
- wherein said second portion includes an upper end and a lower end, and said upper end is integrally formed with said first portion.
A fastener assembly for use in a stucco wall construction, said fastener assembly comprising:
- a first part having an elongated portion, said elongated portion having a substantially uniform cross section along its length;
- and,
- a second part comprising an upper end having an inner surface that tapers inward toward a middle portion of said second part and a lower end;
- wherein said upper end of said second part is integral with said elongated portion of said first part and said elongated portion of said first part extends through a passageway in said lower end of said second part and is separated from said lower end of said second part by a clearance.
