What do you mean by scaffolding?
Scaffolding is a brief structure to bolster the first structure and in addition laborers utilize it as a stage to bear on the development works. Sorts of scaffolding differs with the kind of development work. Scaffolding is comprised of timber or steel. It ought to be steady and solid to bolster laborers and other development material set on it.
Kinds of Scaffolding used in Construction
- Singular scaffolding
- Dual scaffolding
- Suspended scaffolding
- Cantilever scaffolding
- Patented scaffolding
- Trestle scaffolding
Single Scaffolding:
Single scaffolding is for the most part utilized for block workmanship and is additionally called as block layer’s scaffolding. Single scaffolding comprises of measures, records, putlogs and so forth., which is parallel to the divider at a separation of around 1.2 m. Separate between the norms is around 2 to 2.5 m. Records interface the gauges at vertical interim of 1.2 to 1.5 m. Putlogs are taken out from the opening left in the divider to one end of the records. Putlogs are set at an interim of 1.2 to 1.5 m.
Double Scaffolding:
DoubleScaffolding is for the most part utilized for stone brick work along these lines; it is likewise called as mason’s scaffolding. In stone dividers, it is difficult to make openings in the divider to bolster putlogs. In this way, two columns of scaffolding is developed to make it solid. The principal column is 20 – 30 cm far from the divider and the other one is 1m far from the main line. At that point putlogs are put which are bolstered by the both casings. To make it more solid rakers and cross supports are given. This is likewise called as free scaffolding.
Cantilever Scaffolding:
This is a kind of scaffolding in which the gauges are upheld on arrangement of needles and these needles are taken out through gaps in the divider. This is called single casing sort scaffolding. In the other sort needles are strutted inside the floors through the openings and this is called autonomous or twofold casing sort scaffolding. Care ought to be taken while development of cantilever scaffolding.
Situations where cantilever scaffoldings are used:
- At the point when the ground does not having the ability to bolster measures,
- At the point when the Ground close to the divider is to be free from movement,
- At the point when upper part of the divider is under development.
Suspended Scaffolding:
In suspended scaffolding, the working stage is hanging from top with the support of wire ropes or chains etc., it can be higher or lowered to our necessary level. This kindof scaffolding is used for repair works, paintings, and pointing.
Trestle Scaffolding:
In Trestle scaffolding, the working platform is backed on portable tripods or ladders. This is normally used for actions inside the room, such as paintings, repairs etc., not exceeding the height of 5m.
Steel Scaffolding:
Steel scaffolding is built by steel tubes which are set together by steel couplers or fittings. It is very simple to join it or dismantle. It has higher strength, longer permanence and greater fire resistance. It is not inexpensive but will give higher safety for workers. So, it is used widely nowadays.
