1、ANCHOR BOLTS,DEFINITIONDIFFERENT KINDS OF ANCHOR BOLTS,ANCHOR BOLTS,An anchor bolt is used to attach objects or structures to concrete.There are many types of anchor bolts,consisting of designs that are mostly proprietary to the manufacturing companies.All consist of a threaded end,to which a nut an

2、d washer can be attached for the external load.Anchor bolts are extensively used on all types of projects,from standard buildings to dams and nuclear power plants.TYPE OF ANCHOR1.Sleeve2.Wedge3.Hollow Wall4.Heavy Duty Shield5.Toggle6.Ceiling 7.Metal Hit8.Split Drive9.Saw,10.Metal Frame11.Express Nai

4、potting is not necessary.,Step by Step Anchor Installation Instructions follow:,Drill hole same diameter as anchor diameter and 6mm to 12mm deeper than expected embedment.Clean hole of all debris.Set the nut flush with the top of the sleeve anchor.Insert anchor through fixture into hole in base mate

5、rial until washer and nut are tight against the fixture.Turn nut until finger tight.Use wrench to set sleeve anchor by turning nut 3 to 4 times full turns,2.WEDGE ANCHORS,Wedge anchor are widely used for securing all sorts of things to concrete.Each is applied by inserting it in a hole drilled in co

6、ncrete.The hole diameter is identical to that of the anchor;thus each must be driven into the hole.,Drill hole 12mm deeper than the wedge anchor embedment using a carbide tipped bit.(Hole size is wedge anchor size).Clean out hole.Place nut on the end of wedge anchor(protects thread during installati

7、on).Hammer wedge anchor into hole deep enough so that threads are below surface of base material.Tighten nut turning approximately three to four times full turns,Step by Step Anchor Installation Instructions follow:,3.HOLLOW WALL ANCHOR,Hollow Wall Anchors are all metal,pre-assembled fasteners for u

8、se in cavity walls.Suitable for light weight fixing to thin board or plasterboard.,How to use Drill the correct size of hole to the material then tap the hollow wall anchor into the hole until flush with surface.Turn the screw with a suitable screwdriver to expand the anchor.Remove the screw and pla

9、ce through the hole in the fixture and back into the hollow wall and then re-tighten the screw.,4.HEAVY DUTY SHEILD ANCHOR,Heavy Duty Shield Anchor has a high retaining Power and can be removed easily.When tightening the nut or screw the conical section is pulled into the anchor shells expanding it

10、and wedging it inside the anchor base.,Step by Step Anchor Installation Instructions follows:,Using a diameter which equals the anchor diameter,drill hole to minimum embedment.Drive shield anchor till washer is flush with material to be fastened.Expand anchor by tightening nut or head three to five

11、times full turns.,4.HEAVY DUTY SHEILD ANCHOR,4.HEAVY DUTY SHEILD ANCHOR,5.1.SPRING TOGGLE ANCHOR,Spring Toggle is a special cavity wall anchor made of steel.The wings open independently by a spring action.Good for small cavity depth.,Technical Data Sheet,5.1.GRAVITY TOGGLE ANCHOR,Does not have wing

12、that open independently by spring action.,TOGGLE ANCHOR INSTALLATION PROCEDURE:Drill clearance hole in plaster or wall board.Insert assembled screw and body through fixture into hole.Ensure toggle has fully passed into cavity and has dropped down.Tighten screw to desired position.Do not remove screw

13、 or toggle will be lost.,6.CEILING ANCHOR,7.METAL HIT ANCHOR,The Metal Hit Anchor is a precision die-cast,light-duty concrete anchor combining unusual toughness and remarkable strength.The Metal Hit anchor consists of a cylindrical zinc alloy body and zinc plated steel pin expander.The shank,from th

14、e bottom up,is split a major portion of its length.The anchor body has a bore,which runs through the head thickness and into the shank for a depth just beyond the point where the slot terminates in the body.The steel pin expander is made of high carbon steel,properly heat treated,and heavily zinc pl

15、ated for maximum corrosion resistance.,Anchor FeaturesWorks in concrete,brick or block.Hole size is anchor diameter.Corrosion resistant body made form Zamac 3 zinc alloy.Relatively tamper proof.Nail comes in stainless steel.Dead loads only.Not recommended for overhead applications.,7.METAL HIT ANCHO

16、R,8.SPLIT DRIVE ANCHOR,The split drive anchor is a one-piece tamper-resistant,pre-expanded anchor.The anchor is designed for use in solid base material such as concrete.They are available in high strength,heat-treated alloy steel,zinc plated in either a flat or round head style.Light to medium duty

18、R,Anchor FeaturesSimply drill and drive.Fixes over the total embedment length.Virtually stress free fixing that is non-corrosive.Ideal for economical,rapid and repetitive installations.Manufactured from hardened spring loaded steel in a zinc yellow passibeated finish.Specially designed non-tangle en

19、ds speeding up multiple installations.,Express Nail Anchor is a special designed built-in plug with powerful expansion.Fast and easy to use.,12.NYLON ANCHOR,Nylon Anchors are a light duty nail expanding anchor for solid masonry and hollow wall constructions.The design of the expansion nail used in t

20、he Nylon Anchor is such that it can be removed if need be.It has a small slot across the head of the nail to accommodate a small screwdriver blade,when turned anti-clockwise by the screwdriver the nail will be wound part way back out of the nylon sleeve.This enables a claw hammer to be hooked under

21、the protruding head of the nail and pulled out of the nylon sleeve.Having withdrawn the expansion nail fully you can now pry out the nylon anchor body.,12.NYLON ANCHOR,COUNTERSUNK HEAD:Use in solid concrete and masonrySteel zinc plated or stainless steel expansion screwROUND HEAD:Use in solid concre
