WQI 44 PLUS CHEMICAL INJECTION ANCHOR BOLT

• ETA International Certification;
• F 120 report for threaded bar and F 180 for rebar;
• High resistance to chemicals and bad weather;
• Applicable in dry, humid and submerged holes*;
• Fast curing;
• Does not drip (applicable in holes in the ceiling);
• Applied with standard studs, threaded rods, and rebars;
• High strength and reliability fixation;
• Meets static and dynamic loads;
• Suitable for applications in solid and hollow bases**;
• Styrene-free formula;
• Does not create tension in the concrete, which allows for smaller distances between fixings;
• Uses Walsywa 345 or 380 ml applicator;
• Can be reused by changing the mixing nozzle.

*Submerged applications in fresh water only. Use up to Ø 5/8” (16 mm) rod.

**With the help of sleeves.

• Fixation of metallic structures in general, machinery and equipment;
• Fixing railings, handrails,stairs, and gates;

• Fixing anchor bars;
• Metal consoles;
• Overhead cranes;
• Fixing pull-outs (rebars).

Image01: Methods of application on solid foundations (solid concrete, solid masonry and natural stone) 1 Drill the hole with the indicated diameter and depth;

Image02: 2 Inject air to remove excess powder from the hole;

Image03: 3 Thoroughly clean the hole with the aid of a brush, blow and brush until there is no more dust;

Image04: 4 Insert the mixing nozzle into the hole and fill ¾ of the total with resin;

Image05: 5 Insert the stud with a twisting motion;

Image06 6 Wait for the curing time recommended in the table;

Image07 7 After curing, position the element to be fixed and torque.

Fixing threaded rods

Rebar fixing

*Last resin load in 30 Mpa concrete. Values obtained together with the parameters described in the respective tables. For practical applications a safety factor must be used (see page 49).

• Other values can be found in document TR029 and in ETA certificate 12/0167 of WQI 44 Plus;

• “Handling time” is the time in which it is possible to manipulate the product after mixed;

• “Curing time” is the time when the resin “dries” completely and can receive loads;

• Pullout tests must be done 24 hours after the final curing time;

• After curing, keep at room temperature up to 40°C;
• To know the ultimate load by traction and shear of the threaded rods.

• Do not cut the mixing nozzle;
• Clean the hole correctly as explained in the solid base application method;
• At the time of application, the tube must have a temperature above 15°C;
• Do not apply the product to holes drilled with a diamond hole saw. For this application, use the WQE 500 or WQE 500 Plus anchor bolts;

• To design the chemical fixation, use the calculation document TR029 together with the ETA 12/0167;

• To design the chemical fixation in seismic regions, use the calculation document TR045 together with ETA12/0167;
