Scaffolding is a temporary structureused to support people and material in

the construction orrepairofbuildings

and other large structures. It is usuallya modular system ofmetalpipes or

tubes, although it can be from othermaterials. Bamboo is frequently used

inAsia.

Tubes- are usually made either of steel or aluminium, althoughthere is composite scaffolding, which uses filament-wound tubes of

glass fibre in a nylon orpolyestermatrix, because of the high cost of

composite tube, it is usually only used when there is a risk from

overhead electric cables that cannot be isolated. If steel, they are

either 'black' or galvanised. The tubes come in a variety of lengthsand a standard diameter of 48.3 mm. (1.5 NPS pipe). The chief

difference between the two types of metal tubes is the lower weight

of aluminium tubes (1.7 kg/m as opposed to 4.4 kg/m) and also their

greater flexibility and so their lower resistance to force. Tubes are

generally bought in 6.3 m lengths and can then be cut down tocertain typical sizes. Most large companies will brand their tubes with

their name and address in order to deter theft

The basic components of scaffolding are tubes,

couplers and boards.

Boards-provide a working surface for scaffold users. They areseasoned wood and come in three thicknesses (38 mm (usual),

50 mm and 63 mm) are a standard width (225 mm) and are a

maximum of 3.9 m long. The board ends are protected either

by metal plates called hoop irons or sometimes nail plates,

which often have the company name stamped into them.

Timber scaffold boards in the UK should comply with therequirements of BS 2482. As well as timber, steel or aluminium

decking is used, as well as laminate boards. In addition to the

boards for the working platform, there are sole boards which

are placed beneath the scaffolding if the surface is soft orotherwise suspect, although ordinary boards can also be used.

Another solution, called a scaffpad, is made from a rubber base

with a base plate moulded inside; these are desirable for use

on uneven ground since they adapt, whereas sole boards may

split and have to be replaced

Couplers-are the fittings which hold the tubes together. The most

common are called scaffold couplers, and there are three basic types:right-angle couplers, putlog couplers and swivel couplers. To join

tubes end-to-end joint pins (also called spigots) or sleeve couplers

are used. Only right angle couplers and swivel couplers can be used

to fix tube in a 'load-bearing connection'. Single couplers are not load-

bearing couplers and have no design capacity.Other common scaffolding components lnclude base plates, ladders,

ropes, anchor ties, reveal ties, gin wheels, sheeting, etc. Most

companies will adopt a specific colour to paint the scaffolding with, in

order that quick visual identification can be made in case of theft. All

components that are made from metal can be painted but items thatare wooden should never be painted as this could hide defects.

Despite the metric measurements given, many scaffolders measure

tubes and boards in imperial units, with tubes from 21 feet down and

boards from 13 ft down.

Basic scaffoldingThe key elements of a scaffold are standards, ledgers and transoms

The standards, also called uprights, are the vertical tubes that transfer the

entire mass of the structure to the ground where they rest on a square base

plate to spread the load. The base plate has a shank in its centre to hold the

tube and is sometimes pinned to a sole board.

Ledgers are horizontal tubes which connect between the standards.

Transoms rest upon the ledgers at right angles.

Main transoms are placed next to the standards, they hold the standards in

place and provide support for boards; intermediate transoms are those

placed between the main transoms to provide extra support for boards

Specialty scaffolding Putlog scaffold

- A putlog scaffold may also be called a bricklayer's scaffold. As such, thescaffold consists only of a single row of standards with a single ledger. The

putlogs are transoms - attached to the ledger at one end but integrated into the

bricks at the other.

- Spacing is the same on a putlog scaffold as on a general purpose scaffold,

and ties are still required. In recent years a number of new innovations havemeant an increased scope of use for scaffolding, such as ladder beams for

spanning spaces that cannot accommodate standards and the increased use

of sheeting and structure to create temporary roofs.

Pump-jack

- A pump-jack is a type of portable scaffolding system. The scaffold rests on

supports attached to two or more vertical posts. The user raises the scaffolding

by pumping the foot pedals on the supports, like an automobile jack.
