Abstract
There is disclosed a clamping device for holding-down a grid-like support member on an underlying flanged support beam, the device being taken in use from the side of the member which is remote from the beam and partly through a space defined between two generally parallel elongate elements of the member, and being manipulatable so as to bring the device into gripping engagement with a flange of the support beam. The device comprises a saddle portion which is shaped so as to be capable of being non-rotatably seated on said elements at said one side of the member, a clamping portion which is engageable with one side of the flange of the support beam which is remote from the grid-like member, and a threaded fastener which interconnects the saddle portion and the clamping portion and which is operable relatively to draw the portions towards each other in order to clamp the grid-like member to the support beam when the saddle portion is seated on the elements and when the clamping portion is in engagement with the flange of the support beam. The clamping portion has a first part which is engageable with said one side of the flange of the support beam and a second part which is generally diametrically opposed to the first part with respect to the axis of the fastener and which has at least two steps each shaped so as to be capable of seating-engagement with one of the elements on a side thereof remote from said one side of the grip-like member. Upon initial installation of the clamping device, the second part of the clamping portion is rotatable by the fastener, as the latter is tightened, until the second part comes into engagement with said one element and one of said steps comes into seating engagement therewith, whereby further tightening of the fastener causes clamping together of the grid-like member and the support beam.
