Faithfull FAIFE10 Aluminium Feather Edge / Straight Edge 3M (10ft)

Product Information

SpecificationThe rolling straight edge is shipped in 3 wooden cases with a total gross weight of 112kg. This method was rejected in favour of a 2m straight edge set on the slab and is the methodis adoptedin the currentBS 8204,BS EN 13670 Execution of concrete structures, the National Structural Concrete Specification and National Building Specification. This document details requirement in term of the maximum permissible number of irregularities beneath a Rolling Straight edge. The Rolling Straight edge is pushed at 1-2km/h and the number of irregularities, their length and distance from start, are recorded.

The wedge blocks which are fitted to either end of the product supports the item as well as providing a set height between the surface and the beam. When used with the metric graduated wedge you can measure any vertical irregularity within a range of 12.

This introduceda 3m straightedge in direct contact with the slab and surface regularity classes SR1, 2, 3, with corresponding permitted deviations below the straight edge of 3, 5 and 10mm. Such agreement should include the number of positions where the straight edge will be placed to check conformity’. UK Mainland excludes Northern Ireland, Scottish Highlands, Offshore Islands and the Channel Islands.

Such agreement should include the number of positions where the straight edge will be placed to check conformity. It is produced as an instrument to assist engineers with construction, quality control and with compliance assessment, of newly laid pavement regularity. These straight edges are excellent for measuring the lateral regularity of a road or floor and can be used with aluminium wedge blocks, which allow the user to determine how accurate the work is on the vertical plain as well. SCCS Survey are a UK leading distributor of Leica Geosytems Surveying Equipment specialising in the sale, hire, repair and calibration of surveying equipment.If the rate of testing is not known, then we would recommend the following formula to calculate the minimum number of straight edge tests. These are usually but not always specified on mezzanine decks or retail units where tiling is to be received.

The national specifications for surface regularity are then compared and the pavement accepted or rejected and or remedial work undertaken. Measure the greatest gap from the underside of the straight edge, between the points which are in contact with the floor surface.

For a proposed revision of BS 8204 in 2003, a straight edge with feet was again suggested, which was intended to be more portable than the 3m straight edge.The Rolling Straight edge simulates a 3m rigid straight edge sliding along the road surface, and consists of a rigid frame supported on rubber-tyred wheels arranged in two parallel rows, with the centres of the wheels in one row opposite the gaps between the two parallel rows of supporting wheels, is free to move such that it detects vertical movements of this wheel which are then transmitted to a pointer and scale, on the instrument head. This consistedof a collapsible 3m long frame with a wire stretched to standard tension from which to measure the deviation was proposed. The idea was to assess unevenness below the temporary datum of the straight edge as a +/- measurement. Also available in lengths of 300 mm, 500 mm, 600 mm, 800 mm, 1000 mm, 1250 mm, 1500 mm, 1850 mmand 2000 mm. The straight edge also has an odometer for accurate determination of distance travelled in units of 1 metre.
