CLAMP TO SUSPEND A PAIR OF BEAMS IN MAIN T IN PARALLEL RELATIONSHIP.

摘要

A clamp (36) for suspending a pair of main grid T-beams (11) in parallel relationship spaced horizontally with each other, the grid T-beams (11) being the type that have the general configuration of an inverted T-beam and a reinforcing bulb (14) of a predetermined width adjacent to the upper edge of a central core (13), including the clamp (36) surface areas (46, 47) to hold generally opposite vertical sides of the core (13) of each of the spaced T-beams (11) to thus hold the T-beams (11) in respective relative horizontal positions, and surface areas (46a, 47a) to hold the lower portions of the bulbs (14) to support the T-beams (11) in respective vertical positions, a portion of main body (37) that generally extends horizontally between the fastening surface areas for spaced T-beams, characterized in that the clamp (36) has a pair of elongated transverse notches (53) arranged on opposite sides of an imaginary vertical vertical plane transverse to its length, the notches (53) extend across the width of the main clamp section (37), the notches (53 ) are spaced apart from each other to leave a central support portion (54) having a width equal to or substantially equal to the width of a conventional reinforcing bulb (14).
