Abstract: Facility for installing or for system testing of floor or ceiling-mountable x-ray systems with radiation protection cabins with radiation-proof, especially lead-lined, walls and doors, with each radiation protection cabin (1) having a sliding door (7, 7?) occupying at least a majority of the cabin wall, made up of several lead-shielded door elements (7a, 7b, 7c) which can slide telescopically over one another and are preferably hung from a ceiling mount at a slight distance from the floor to allow them to slide freely and separate the internal operating space (5) of the cabin (1) from the operating console (4) for the x-ray system arranged in front of it, with the door elements (7a, 7b, 7c) being equipped with lead-shielded side edges (9) overlapping in their closed position such that radiation cannot escape from the interior of the cabin through the gap between two adjacent door elements (7a, 7b, 7c), and with a door closing monitoring system being provided to which the operating system of the x-ray system i

Abstract: A deck connector that may be cast into a structural concrete element for use in joining adjacent ones of the concrete elements to each other by the use of weld plates that are movably disposed within a weld plate housing forming an element of each of the deck connectors.

Abstract: The current invention is a concrete post anchor and method of using comprising two substantially vertical side brackets, side brackets operatively connected opposite one another and spaced apart with a base bracket and a back bracket forming a U-shaped bracket. A pair of front brackets is removably attached to the side brackets. An anchor and a portion of the side brackets extend below the base bracket forming an anchor tab and a side bracket tab. A pair of anchor rods is operatively connected to each side bracket tab. The anchor can be embedded in a concrete pier and then a post can be secured within the concrete post anchor with the front brackets and fastened to the anchor. The concrete post anchor withstands increased loads and forces associated with post built-type buildings without permitting the wood post to directly contact the soil, thereby creating substantially stronger and longer-lasting post buildings.
