These fall protection anchors are designed to attached directly to a wood truss. These anchors do not penetrate the roof sheathing, they do not pass go, and they do not collect $ If all you have to anchor to is a naked truss, these anchors will do the job.

If trusses are stored horizontally, the blocking should be eight to ten foot centers to prevent lateral bending. If the truss bundleis to be stored for more.
their long service records. The metal plate connector has a year service record with over million in use. Their in-service performance has also been satisfactory. In , the Forest Products Laboratory initiated a study on the longtime performance of trussed rafters with different connection systems. The trussed rafters wereFile Size: KB. Most often made of 2x4s and spaced 24 in. o.c., a truss-framed roof uses less wood than one stick-built from 2x6 or 2x8 rafters and joists 16 in. o.c. How roof trusses work: Triangles are naturally rigid geometric shapes that resist being distorted when pushed on.
The FallTech® Permanent Truss Roof Anchor discussed in this manual is designed to provide an easily installed anchorage for persons working at height on wood structures and subject to fall hazards. The anchor consists of stainless steel, with installation holes and an 11/16”File Size: 4MB. Trusses are made up of four main parts. The upper angled parts correspond to the common rafters used in stick framing roofs. These pieces are known as upper cords and there are two of them in each truss. The bottom horizontal of the triangular truss form, which corresponds to the joists in stick framed roofs, is known as the lower cord.

Evaluation and Repair of Fire Damaged. The use of Metal Plate Connected (MPC) wood roof trusses is a common structural framing system used in residential and light commercial structures.
Low initial cost of fabrication, ease of installation, and ability to accommodate varying profiles are some of the advantages of this type of roof framing system. However, when these trusses are.
Metal Plate Connected Wood Truss Handbook by Edward E. Callahan Pam Sabean (Editor). This is an up-to-date reference on the design, manufacture, handling, installation, and bracing of modern trusses. Written by an engineer with over 25 years in the truss industry, it combines technical information with practical tips and a number of useful.
Floor Truss: A wood truss assembled with nominal 2x4 lumber in the flatwise orientation so that the thickness of the truss is 3 ½” (89 mm). Attic Frame or Attic Truss: An assemblage of wood members that follow the roof and ceiling profile while leaving a large rectangular.

Several other plates on some of the diagonal members have begun to experience plate peeling at the corners, perhaps due to the new stresses as a result of the failure.
When cast-in-place concrete is used as a roof deck some provision must be made for attaching the roof to the deck and is accomplished with wood nailing strips that are either imbedded in the concrete at intervals of ___ feet, drilled and anchored, or placed between rigid insulation panels if.
