make noises during horizontal loading events such as wind or seismic events the methods used heretofore are expensive and labor intensive and require great care to equalize the tension in all the straps the method shown in this invention requires only a fraction of the material and labor costs of previous methods and it is convenient and simple to install and to operate work can be done at a convenient height by a single worker fig1 11 and 12 illustrate in detail the tensioning system used on the diagonal straps the stud 121 has a web that faces the tensioning device this stud is disposed on both sides thereof as shown in fig1 and 11 the diagonal straps 122 are hand tensioned during fabrication to prevent racking of the panel after erection but before the drywall or other finish is placed the straps can be tensioned by the tensioning device pulling the straps into the stud void as shown in fig1 both the device and the bolts can be clear of the drywall finish the bolt may be cut after tensioning if required the straps may be fully welded to the top and bottom plates when hand tensioned as described hereinabove stud bridging is illustrated by numeral 123 a 11 2 inch channel is shown.
