For spacing (edge distance) smaller than critical spacing (critical edge distance ) the design loads have to be reduced (see system design resistance ), Critical spacing and critical edge distance for splitting failure apply only for non-cracked concrete, For cracked concrete only the critical spacing and critical edge distance for concrete cone failure are decisive. a) Only hand setting is recommended

Basic loading data for single anchor in solid masonry units Solid bricks: a reduction of the cross section area by a vertical perforation perpendicular to the bed joint area must not be greater than 15% Drilling: - Holes in Mz and KS drilled with TE rotary hammers drilled with hammering mode - Holes in PPW drilled with TE rotary hammers drilled without hammering mode Installation: -
Make sure that anchor is not spinning in the borehole after the screw anchor head is touching the base plate (Step 4. in the setting instructions). Spinning may lead to significant load drop of the fastening point.
Edge distance and spacing influences: Distance to free edge free edge to solid masonry (Mz and KS) units cmin,free ≥ 200 mm Distance to free edge free edge to solid masonry (autoclaved aerated gas concrete) units cmin,free ≥ 170 mm The minimum distance to horizontal and vertical mortar joint cmin,h and cmin,v is stated in drawing below Minimum anchor spacing in one brick/block is smin = 80 mm

Load values: - The technical data for the HUS-H anchors are reference loads for MZ 12 2,0-2DF, KS 12 2,0-2DF and PPW 6-0,65. - The load Values are valid for non-structural applications. - Due to the natural variation of stone solid bricks, on site anchor testing is recommended to validate technical data. - The HUS-H anchor was installed and tested in the centre area of solid bricks as shown considering minimal edge and space distances. - The HUS-H anchor was not tested in the mortar joint between solid bricks or in hollow bricks; however a load reduction is expected. - For brick walls where anchor position in brick can not be determined, 100% anchor testing is recommended. Limitations of loads: - All data is for redundant fastening for non structural applications - Plaster, graveling, lining or leveling courses are regarded as non-bearing and may not be taken into account for the calculation of embedment depth. - The decisive resistance to tension loads is the lower value of Nrec (brick breakout, pull out) and Nmax,pb (pull out of one brick). Pull out of one brick: The allowable load of an anchor or a group of anchors in case of single brick pull out, Nmax,pb [kN], is given in the following tables: Clay bricks:
