Abstract: A seismic adapter for attachment to a steel web joist including two beams with the upper beam having laterally extending flanges with a wood nailer positioned thereon includes two brackets. Each bracket is a plate formed to define a base section, a mounting section and an engagement section. The mounting section is adjacent and perpendicular to the base section while the engagement is also adjacent to the base section and extends at an obtuse angle therefrom. A passage extends through the wood nailer with a shaft extending therethrough to rigidly retain the mounting sections against the wood nailer. The passage has a center distance above the undersurface of the laterally extending flanges which is greater than the distance from the axis of the holes of the mounting sections to the edges of the engagement sections.

Abstract: A retaining strap for use in supplementing the securement by a C-clamp of a load carrying rod to an I-Beam in steel construction. The strap defines an arcuate slot proximate one end thereof which is adapted to be hooked about the load carrying rod such that the strap can be extended across a portion of the I-Beam and a second extended end portion of the strap bent about the I-Beam to enhance securement of the rod to the I-Beam. In a second embodiment of the invention the slot is formed in a perpendicular disposed ear portion adjacent one end of the strap which is adapted to engage a leg portion of a "U"-shaped hanger such that the strap can be extended across the hanger and the extended end bent about and secured to a second leg of a hanger for securing a fluid carrying conduit within the saddle of the hanger.

Abstract: An adjustable load bolt adapter bracket assembly for use with a sway brace in securing a bracing element between a fluid pipeline and a structure to anchor the pipeline to the structure and limit relative movement therebetween. The assembly comprises an attachment member and an adapter plate. The attachment member includes a flat plate portion having an upstanding lateral wall adjacent one end thereof, at least one fastener receiving aperture therein, a bracing element receiving member pivotedly mounted on the lateral end wall and a plurality of locking channels in the opposite sides and one end thereof. The adapter plate defines a plurality of spaced fastener receiving apertures axially aligned therein and a locking tab extending from one side thereof and one end thereof. Alternative, the locking channels can be provided in one end and one side of the adapter plate and the locking tabs in the opposite ends of the plate portion of the attachment member.
