Scaffolding Stevenage is the supporting metal rods, which were used during construction. As they are used in building a wide array of structures, they are of numerous kinds to meet the specific building type. However, there are some basic elements but their designs and the way it is fixed varies according to the type of building used for construction. The main elements of tube and coupling scaffold include three components:
A standard is a long tube that connects the scaffold directly to the base. The base of each standard is connected to a base plate, which distributes the weight of the other standards. The standards are of fixed length. Taller scaffolding requires that the pipe is connected firmly to the ground so that load is structured. They have a twist and socket joint that locks the successive pipes together. One pair of standards is placed at the back of the scaffolds nearest to the building and the other pair at the front. These two pairs of the scaffold form a bay that has the side to side dimension i.e. length and back to front dimension i.e. width.
They are the flat tubes that join two standards. They are running horizontally along the length in between each standard. It also supports and distributes weights. Lift is the row of ledgers that run parallel to buildings that are fixed to the standards. The ledgers are manufactured from size 48.3mm O.D with forged steel blades placed at the bottom of the standards that lock the corresponding cups. They are available in various sizes to provide the desired grid dimension for scaffolding. Some of the available sizes are 1.20m, 1.30m, 1.60m 1.80m 2.50mm,
These are also known as bearers. It leans on the ledger at the angle of 90 degrees. They are mainly positioned near to the standards. They provide simple and fast erection support to the standards by holding them in positions that are placed on boards or planks. To provide more support intermediate transoms are placed between the main transoms. They allow easy assembling and disassembling of support systems. They are used as safety rails to end bays. There are many types of transom such as cuplock ledger transoms, Intermediate transom, and open-end transom.
In addition to these, several supportive elements reinforce the establishment of scaffolding. These are:
Scaffolding tubes: they are generally made from steel or aluminium. The steel is generally hot-rolled steel. In a special case like live overhead electric cables, filament-wound tubes of glass fiber in polyester or nylon matrix were used for safety.
Scaffold coupler: they are the fittings that hold the tubes together. There are three basic types of couplers right-angle couplers, putlog couplers, and swivel couplers. One more type of coupler is a sleeve or joint pins, which are used to join tubes, end-to-end.
Adjustable base plate: they come with self-cleaning technology, which surrounds threads to adjust on the ground. The can be adjusted according to the height of the scaffold. It has a special feature that comes with a notch and colour marking which render safeguards against over-winding.
Diagonal braces, toe board, and decks are other supportive elements of the scaffold.
