Wire Loop Boxes

Wire Loop Box Introduction

The Wire Loop Box will need to fixed to the formwork and the flexible folded wires will need to be pulled out to make a connection when ready on site. The load will be transferred from one concrete panel to the other panel via a wire rope loop. High strength (1770 MPa) Galvanized Steel Wire Rope with 6 mm ɸ will need to be crimped by using compression sleeves / Ferrule to form a loop at one end & to transfer a load axially through the other end. The load is transferred from one concrete panel to the other panel via a wire rope loop.

Wire Loop Box Features

●Connecting Loop consists of a recess box that anchors itself to concrete well thanks to its stepped side form, and a wire, which together with the box forms are a load-bearing structure.

●The spacing of GME Connecting Loops in the joint depends on the shear loads to be transferred.

●Boxes are installed to the formwork of wall panels before concreting. Wire Loop boxes are installed to the formwork according to spacing needed to bear the shear loads before the panel is cast.

●After removing the formwork, protective tape is removed and the loop is opened with for example a hammer or a pin.

●Pair of boxes and the vertical rebar installed into loops form a joint which resists vertical shear forces, together with the concrete grout in the joint.

The key benefits for the wire loop box are as below

●Easy to install, individual boxes are installed to formwork

●High Strength Galvanized Wire Loop

●Pre-punched nail holes for easy fixing to formwork

●Galvanized steel casing ensuring stability during fixing and concreting

●For construction junction between precast segments

●The loops pop-up automatically ensuring time-saving; no rebending is required

●1770 Mpa wire rope, zinc plated

●Color-coded plastic clips

●Ideal for butt junction between wall to wall and wall to column

●Product dimension ideal for logistics and storage

●A flexible wire loop stays in the open position due to the patented structure.

●Anchoring tail is easy to place into reinforcement.

●Stepped box shape secures the box into the concrete

Thailand thin panel wall connector loop box for 10mm thickness wall:

How this special connector loop box work at 100mm thickness panel wall:

Comparisons between our products and Thai products are as follows:

1.Our products VS Thai market products

2. Holes

Our hole diameter is more consistent, the hole diameter of the Thai is not neat, get imbalanced. Both beautiful and unbalanced condition without risk of Safety

3. Mold, our products have a very strong space.

The deeper the curve, the deeper the stick and attract the surface more, the result will be better.

4. The surface of our side is quite deep. The quality feels better. The texture of the products in the Thai market is slightly shallow, coarse.

5. Our glue is tougher than Thai products.

6. The plating of our rope is brighter

7.Our products are a little bigger, use more materials like this, better quality.

How do to use Wire Loop Box?

In precast factory

Connecting Loops are fixed to the formwork with nails. The common way is to make a plywood strip, which forms the recess shape to the wall panel end. Then nailed with correct spacing to this reusable

plywood strip. When the concrete has hardened and formwork is removed, protective tapes can be removed, and loops opened for example with a hammer. Due to the patented structure of the wire, loops will remain in open a horizontal position.

On construction site

Wall panels are installed according to plans and supported. Vertical rebar is installed into a joint, and the horizontal position of the loops is checked. After formwork has been

done, concrete grout is poured or pumped into the joint.
