3000 Range Frame Cramp

Details

Details

The 3000 Range Frame Cramp has a slotted upstand which provides the user with vertical tolerance when fixing the products to the structure, reducing the likelihood of the frame cramp being bent on site to suit brickwork coursing.

The frame cramp also has a unique shape and multi drip feature, the staggered spacing ensures a drip is positioned within the open cavity and the shape causes water droplets to roll off the tie, preventing moisture passing across.

Manufactured with a safety end, the frame cramp also has 3 holes to assist with adhesion into the mortar. The shape of the product also allows for a debonding sleeve to be used for movement joints.

The specific features of this tie mean it can be used for various applications throughout a whole project. For more details about the universal frame cramp contact our technical department.

Technical Data

The ACS 3000 range wall tie is a multi-purpose frame cramp designed in accordance with the requirements of BS EN 845-1. The wall tie is designed to allow a masonry panel to be tied back to a range of structures/substrates meaning one wall tie can fulfil a range of applications on site. The advanced punched and pressed profile of the wall tie means that it is capable of withstanding high loads as a result of its increased sectional properties. The wall tie is resistant to water crossing a cavity due to the integrated ‘drip’ features that serve to prevent the transgression of water from the outer leaf to the inner leaf of a building even when installed with an angle of up to 5° in an unfavourable direction. A standard de-bonding sleeve can be supplied for use at movement joints. The minimum mortar joint thickness for which this wall tie is intended for use is 10mm.

This tie has been independently tested at Sheffield University Civil and Structural Engineering Department and results have shown that this product is inherently stronger than the traditional style cramp that is widely available in the marketplace at present.

The performance of frame cramps is determined by the position of the fixing. At the lowest point of the slot, the frame cramp will have a declared load capacity of 1.0kN. As the fixing position alters the capacity of the tie will reduce. ACS recommends using oversize washers with the fixing when installing cramps with a vertical slot.

Tie Dimensions and Standard Tie Lengths

Installation & Best Practice

Wall ties should typically be installed at a density of at least 2.5 ties/m2 for walls in which both leaves are thicker than 90mm. This can be achieved by spacing the wall ties at 900mm horizontal centres and 450mm vertical centres, staggered at alternate courses.

Wall ties should be evenly distributed over a wall except around openings or at an un-bonded panel edge where the tie density should be increased to 225mm vertical centres within 225mm of the opening or edge

The length of the tie should be sufficient to allow an embedment of at least 62.5mm meaning that the minimum embedment of 50mm is always achieved after allowing for site tolerances.

Declared Load Capacity

The ACS 3000 range wall tie has been tested in accordance with BS EN 846-6: 2000 for the determination of tensile and compressive load capacity and load-displacement characteristics of wall ties (single end test). Based on the results of the tests the capacities declared in the table below were established.

ACS can supply a range of corrosion resistant fixings to suit various applications. The list in the table above represents typical fixings used. For more information or alternative fixings please contact the ACS Technical Department.
