  6. Our locations Founded in the Black Forest Worldwide success – in 47 subsidiaries Brazil Czech Republic Italy Argentina China Germany USA > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  7. Divisions creates comfort and organization in cars – from cupholders to complete multifunctional consoles, for both national and international car manufacturers. offers a unique and complete range of products for the areas of plastic, steel and chemical fixings as well as additional ranges for experts and DIYers. is an intelligent construction kit for children – and much more. Even industrial machines and plants can be simulated into the smallest detail. also gives other companies access to fischer’s outstanding knowledge for the improvement of internal company processes and for preventing waste. develops, manufactures and distributes custom so-called capacitive Touchsystems and Multitouch systems. LNT also develops and produces for all of fischer’s divisions > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  8. What is an Anchor?? A B Anchor bolts are used to connect structural and non-structural elements to the concrete, masonry, boards etc. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  9. TYPE OF ANCHORS > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  10. Concrete  Resin Bonding Anchors  Expansion Anchors  Undercut Anchors > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  11. Fun quiz!!! Who founded the first Nylon Plug? Prof. Arthur Fischer > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  12. Main Factors Affecting the Anchor Performance Drill Method Base Material Anchor Layout Load Type Load Directions > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  13. Material Anchor selection depends on material The following differentiation is made: Concrete is a material containing cement Masonry is a composite material made from stones and mortar Board elements are thin-walled materials made from plasterboard, hard fibres, plywood etc. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  14. Material Concrete Concrete comprises two sub-groups: Normal concrete Lightweight concrete > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  15. Material Concrete fails under low tensile loading (approx. 10% of compressive strength). Cracks in concrete from tensile loads. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  16. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  17. What is the influence of cracks on the performance of anchors ? Anchors suitable for cracked concrete:  The load bearing capacity of anchors, designed for use in cracked concrete, is reduced by approximately 30% compared to non-cracked concrete > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  18. Material Masonry materials Solid blocks with dense structure Perforated materials with dense structure Solid blocks with porous structure Perforated materials with porous structure > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  19. Material Material: board elements The third main group consists of thin-walled materials that are often very low in strength. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  20. Material Tip for board elements Here, the anchors selected should be those that induce forces through form-fit, e.g. anchored directly on the back of the board in the cavity. Board fixing PD Suitable anchors for this are normally called cavity fixings. Metal cavity fixing HM-S > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  21. Drilling method Impact drilling = Turning motion Hammer drilling = Turning motion Small no. of impacts High impact energy. Rotary drilling = Only turning Motion. Large no. of impacts Low impact energy. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  22. Fun Fact!!! Prof. Arthur Fischer had more patents than Edison. 1100 Patents! Did you Know? He invented the modern flash light. > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  23. Stress Possible stress directions for an anchor N N R V Oblique tension Tension V V Bending + shear force Shear force > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  24. Stress Stress type Predominantly static load Dynamic load Shock load > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS

  25. Action and resistance Part of the structure to which the fixture is attached. The most important dimensions are: h Member b Member width b s Member thickness h c2 c1 Spacing s Edge distance c Anchorage depth hef hef > WEBINAR EXPERTS GUIDE TO WORLD OF ANCHORS
