Floor Fixings 5

Floor FixingsWhen designing the floor fixing range of products for chequer plateand both square and rectangular open bar grating Lindapter combinedspeed with ease of installation. None of the products require any sitedrilling and/or welding to be done and can easily be installed fromabove the flooring; this means no requirement for scaffold towers,access platforms or MEWP hire giving easier compliance with theonerous work at height regulations.

Both the Floorfast ® & Grate-Fast ® are covered by Lloyds Register TypeApproval in respect of their clamping force and resistance to looseningin areas subject to shock and vibration. Without a need for the issuingof hot work permits, they are particularly suited to applications wheresafety is of paramount importance such as in offshore and onshorepetrochemical and processing industries although they are equallyideal for applications in all other industrial environments.

Type FF - Floorfast®

Malleable iron, Stainless Steel Grade 316,bright zinc plated / hot dip galvanised

The product consists of a malleable iron body castingwith a countersunk socket screw; the eccentric steppedweb of the casting allows it to lock under the steelworkproviding full face contact when torque is applied.For thicker flanges packing pieces will be supplied.Lloyds’ Register Type Approval covers clamping forceand vibration.

1. Pre-assemble Floorfast ® on underside of floorplatewith stepped surface facing inwards.

2. Align castings with straight edge parallelto the edge of the plate and hand tighten.

3. Lay floorplate into position4. Using a hexagon key release the countersunk screw

one full turn.5. Tighten down the countersunk socket screw.RemovalUsing a hexagon key, give the Type FF one full anticlockwise turn to release connection from the flange.

Type GF - Grate-Fast®

Body: Malleable iron, mechanical galvanisedTop Hat: Mild Steel, mechanical galvanised

Installation1. Position pre-assembled Grate-Fast ® with body

between grating bars and nose pointing towards thesteelwork. The arrows on the top hat bracket shouldalso be pointing towards supporting steelwork andbracket itself resting on the bearing bars.

2. Slide Grate-Fast ® towards steelwork until nose fitsunder the beam flange. Where necessary adjustbody/screw to approximate flange thickness/gratingdepth.

3. Tighten cap screw; the Grate-Fast ® body willautomatically rotate until it locks under the bearingbar, with the nose under the flange. Continuetightening to the recommended torque.

1. Position the fixing with the grating bar located between the two tabs on the upper profile, facing towards the supporting steelwork.2. Apply a downward force to the fixing, so that the lower leg passes through the grating.3. Apply a downward force to the top of the fixing. The fixing then snaps in to place. If the lower profile contacts the steelwork web,

the GF3030 will automatically relocate itself.

RemovalUsing a screwdriver or lever, raise the back of the GF3030 into position shown in diagram 2.Place the lever between the steelwork and lower leg of the fixing and prise GF3030 away from steelwork.

Deformed or damaged clamps cannot be re-used.
