Resi-Fix

The Resi-Fix cavity wall tie replacement system, when a resin bond is required
in both inner and outer leafs of differing materials like, air-crete blocks, clay bricks,
stone, and concrete blocks, ideal for small one off jobs of about 30 to 200 ties.

Resi-Fix Ties are manufactured out of 304 or 316 Stainless Steel and have been independently tested using a common range of building materials by the University of Portsmouth material testing department in accordance with BS 1243 and EN10088 They can be installed quickly and easily by drilling a clearance hole through the outer
leaf then 70mm into the inner leaf. After cleaning out the holes with an air pump, fill
the inner hole with resin and then insert Resi-Fix Tie and then fill outer hole with resin. The constant helix of Resi-Fix Ties gives multi water drips stopping water transfer across cavities. The low cross sectional area of Resi-Fix Ties gives good sound proofing qualities and allows lateral flexibility to over come any misalignment or seasonal thermal movement while still maintaining the required resistance to wind-loads.

Installation Procedure



1. Drill clearance hole through the outer leaf and 70mm into the inner leaf.




2. Clean both holes of any dust or debris.




3. Fill inner hole with Tri-Set resin.




4. Insert Resi-Fix tie.




5. Load test Resi-Fix Tie





6. Fill clearance hole with Tri-Set Resin to bond tie to outer leaf.

4.94 TIES PER METRE SQUARE REQUIRE 450MM HORIZONTAL CENTRES AND 450MM VERTICAL CENTRES


NOTE: You can use other tie densities shown on menu 'Tie Densities'. To do this select tie load for your particular site conditions from one of the above two tables, then multiply your selected tie load by the tie density of that table. This will give you the load per metre squared. Then divide the load per metre squared by any of the tie densities shown in 'Tie Densities'. To get the required tie load for that density, you must then install ties to the required vertical and horizontal spacing centres of the selected tie density.

Installation Procedure

A light hammer drill is recommended I.E. no more than 1.5nm impact and not less than 3000 impacts a minute.
1 1. Drill a clearance hole through the outer leaf. Make sure to avoid frogs, core holes. Then drill 70mm into the inner leaf 11mm clearance hole for 6mm Tie, 12mm clearance hole for 8mm Tie then check cavity width for tie selection using TABLE A (Tie Selection Tab).
2 2. Clear outer and inner hole of any brick dust or debris with compressed or air pump.
3 3 Remove plugs and screw on mixing nozzle to Tri-set resin cartridge and place into resin gun, pump resin through mixing nozzle until an even colour is achieved. Then insert nozzle with extension tube through outer clearance hole and across cavity, until just inside the inner clearance hole. Then pump resin until you can fill back pressure of the resin filling hole and pushing extension tube back. Knock off pressure switch and remove nozzle and extension tube.
4 4 Insert tie by passing through outer clearance hole and across cavity
and into resin filled inner clearance hole.
5 5 Before drilling out all the clearance holes, preliminary load tests should be carried out to establish the strength of inner and outer leaf fixing, which should exceed the required load by 20%. TABLE C (Tie Densities Tab) show's all the required loads for each site taking in consideration wind zones, exposure condition, and topography to a height of 15metres. If due to soft inner or outer leaf material test loads are not exceeding required load by 20% tie density can be increased to reduce the required tie load’s see TABLE C (Tie Densities Tab). 5% of all ties installed must be load tested.
6 6 Then insert nozzle into clearance hole until touching tie, pump resin around tie, you must get at least 50mm of resin embedded around the tie, then if resin match’s brick bring resin to the surface and make good with a rag. If resin colour dos not match then hold back 6mm and make good with sand/cement and dyes. When working on render surface’s always hold resin back to the surface of brick and make good with sand and cement.

TRISET PRODUCT DATA SHEET

DESCRIPTION

Triset is a rapid curing 'one shot' two part chemical anchoring cartridge system based on a polyester resin. Applied in one single action to produce a cost effective, tough, chemical resistant fixing. Triset is ideal for close-to edge applications (unlike expansion anchors) as no stress is placed on the surrounding substrate. Versatile in use, Triset is suitable for fixing wall ties, starter bars, studs, bolts or large screws in a wide range of substrates including brickwork, concrete, masonry, stone and PF A blocks. Hollow base materials can be securely fastened into by using Triset in conjunction with a sleeve or sieve.

PREPARATION

1. Drill hole to the correct diameter and depth (see chart for guide), ideally using a rotary percussion machine. For optimum results the hole must be coarse sided. If the holes are produced by diamond drilling the surfaces should be thoroughly roughened.

2. Remove all dust and debris from the hole using a hand air pump or a stiff rotary brush.

3. All bars should be clean and free from oil or grease and all flaking rust should be removed. Threaded rod or struts should be chisel-ended to prevent them being unscrewed from the cured resin.

APPLICATION

1. Attach the mixing nozzle to the cartridge (screw down hand tight).

2. Mount the cartridge into the dispensing gun.

3. Squeeze out material through the nozzle until an even colour is achieved (approximately 5-6 inches of extruded material should be adequate).

4. Apply to the hole working from the base out. Once the required fill is obtained release the pressure and wipe away excess material. Place the bolt or screw into the hole with a rotary action. Wipe away excess material. Attach fixture once resin has cured.

NB Once material has started to extrude through the nozzle, over pressuring the system will not increase flow rate and can cause leakage from the rear of the cartridge.

Tension figures quoted are tested in accordance with BS5080 part 1 in 63 N/mm sq concrete blocks (12 x 12 x 12 inches). In all cases for 16mm and 20mm anchors failure of the concrete block was observed before the anchor was dislodged.



The ultimate pull out strength is varied by:
1. The strength of both the substrate and bar/stud
2. The length of the resin bond to bar
3. Hole preparation
4. Anchor separation

Safety factors of between 2:1 and 4:1 should be considered depending on the strength and nature of the substrate. Due to the inconsistent nature of hollow blocks and bricks tension figures may vary. Site testing should be carried out where necessary to establish particular suitability. In order to achieve maximum performance the distance between the centres of the anchors should be a minimum of2.5 x the embedment depth, and 1.25 x the embedment depth for the minimum distance from edges.

STORAGE

Store in a dry area between 5 C and 25 C. Do not expose to direct sunlight. Storage at higher temperatures will reduce the shelf life.
