How to Use Scaffold Wall Tie Bracket In Construction
Scaffold wall ties are fixed with anchors to the wall by the end plates and hooks at the end. In securing, bolts and eye bolts will tie one end of the wall tie brackets to the wall of the building. Another end of the wall tie bracket will be fixed to the scaffold by scaffold fittings. This system with a wall tie bracket is called a tie scaffold. Tie scaffold prevents scaffold from collapsing under bad weather like high wind etc.
Do all scaffolds need to be tied? Basically, in the scaffolding industry, there is a rule of 4:1, which means if the height-to-base ratio is over 4:1. A tie scaffold with a wall tie bracket to a solid building or structure is needed.
How To Set Wall Tie Bracket In Construction and Scaffolding
The wall tie bracket is connected to scaffold standards/verticals by scaffold fittings, and can not be connected to the ledgers. The time of the wall tie bracket arrangement should be at the same time as the scaffold being erected. Cannot be attached later as an afterthought.
Wall tie brackets should be set every 3 bays horizontally, and the maximum vertical space is 4m or 2 lifts. First vertical wall ties should be at the maximum height of 4 times of the narrowest base dimension.
You can calculate the wall tie bracket quantity for your scaffolding according to the following table of quantity for the vertical height by how many times of 3 bays of horizontal.
Wall Tie Bracket Quantity Calculation
| Wall Tie Bracket Quantity ( Vertical ) | ||
| No. | Scaffold Height | Vertical Ties Quantity |
| 1 | Up To 6m | 2 |
| 2 | Up to 12m | 3 |
| 3 | Up to 18m | 5 |
| 4 | Up to 24m | 6 |
| 5 | Up to 36m | 9 |
Scaffold Stabilizing
For scaffold stabilizing, you need not only to consider wall ties to solid building but also need to use the scaffold diagonal braces and horizontal braces to make the scaffold tower stable and consolidated.
The tie scaffold devices and bracing system can also increase the load capacity in construction and shoring.
Wall Tie Brackets Types and System Scaffold
Wall tie brackets with OD48.3mm scaffold tube are compatible with all scaffold systems including ringlock scaffolding, cuplock scaffolding, kwikstage scaffolding, and tube and clamp.
Wall tie brackets with OD42.7mm(1.68″) are special components for frame system scaffolding (walk-through frame, snap-on scaffold, ladder frame etc), scaffolding in the USA and Canada for masonry, stucco, plastering etc.
Wall Tie Bracket Surface Treatment
Wall tie brackets are made of steel. For anti-corrosion purposes, the surface will be finished by galvanizing, painted or powder coated.
Sizes and Lengths of Wall Tie Bracket
Wall tie bracket lengths are customized from 0.3m to 7′(2.1m) according to the distance between the wall and the scaffold.
