Setting Procedures

1)

Drill hole with hammer drill to the required anchor size and depth.

2a)

Blow the hole clean with hand pump up to hole diameter 20mm.

2b)

Use compressed air (min.6 bar) hole diameter >20mm or depth >240mm.

3)

Brush the hole with appropriate size wire brush.

4a)

Blow the hole clean again with hand pump minimum 2 times.

4b) 

Blow the hole clean again with compressed air (min. 6 bar)

5) 

Attached static nozzle and load the cartridge into dispensing tool.

6)

Mark embedment depth on the rebar. The bar should be free of dirt.

7)

Discard non-uniformly mixed until mortar shows consistent grey colour.

8)

Fill the hole up to approximately 2/3 with adhesive.

9)

Use piston plug for overhead installation.

 

10)

Push the rebar into the hole while slightly turning action.

 

11)

Be sure the rebar is fully embedded and excess mortar is visible.

 

12)

Allow the adhesive to cure prior to applying any load or torque.

Influencing Factors

Influence of Concrete Strength

= 150mm concrete cube compressive strength

Influence of edge distance*

*The above influencing factors must apply for every edge distance smaller than critical edge distance . Actual edge distance shall not be smaller than minimum edge distance .

Influence of anchor spacing**

**The above influencing factors must apply for every anchor spacing smaller than critical spacing distance . Actual anchor spacing distance shall not be smaller than minimum spacing distance .

Influence of anchorage depth

Influencing Factors

Influence of Concrete Strength

= 150mm concrete cube compressive strength

 

Influence of anchorage depth

 

Influence of shear loading angle

Influence of anchoring spacing and edge distance for concrete edge resistance

Formula for single-anchor fastening influenced only by edge

Formula for two-anchor fastening valid for S<3c

General formula for n-anchor fastening (edge plus n-1 spacing) only valid where to are all <3c and > 1.5c   

Note: It is assumed that only the row of anchors closed to the free concrete edge carries the centric shear load.
