This set of Construction & Building Materials Questions and Answers for Aptitude test focuses on “Component Parts of a Scaffolding”.
1. The temporary framework is known as __________ and it is useful in construction demolition, maintenance or repair works.
a) Underpinning
b) Shoring
c) Scaffolding
d) Grouting
View Answer
Explanation: When the height above floor level exceeds about 1.5 m a temporary structure, usually of timber, is erected close to the work to provide a safe working platform for the workers and to provide limited space for the storage of plant and building materials. This temporary Framework is known as scaffolding or simply of scaffold.
2. ___________ is the most common type of scaffolding and is widely used in the construction of brickwork.
a) Suspended scaffolding
b) Single scaffolding
c) Trestle scaffolding
d) Steel scaffolding
View Answer
Explanation: Single scaffolding or Bricklayers scaffolding consists of a single row of standards placed at a distance of about 1.20 m from the wall. The distance between the successive standards is above 2 metre to 2.50 m. The ledgers are then fixed to the standards at a vertical distance of about 1.20 metre to 1.80 metres.
3. _________ is stronger than the single scaffolding and it is used in the construction of stone work.
a) Trestle scaffolding
b) Steel scaffolding
c) Patented scaffolding
d) Double scaffolding
View Answer
Explanation: In Double scaffolding or Mason’s scaffolding, the Framework is similar to the single scaffolding accept that two rows of standards are provided. The distance between the face of the wall and the first show of standard is about 200 mm to 300 mm and the distance between the two rows is about 1 m.
4. __________ type of scaffolding is used when the proper hard ground is not available for the standards to rest.
a) Steel scaffolding
b) Trestle scaffolding
c) Bricklayers scaffolding
d) Cantilever scaffolding
View Answer
Explanation: In Cantilever scaffolding or Needle scaffolding, the general Framework maybe of single scaffolding type or of double scaffolding type. Thus but the standards are supported by a series of needles or ties which are taken out at floor level or through opening or through hole kept in the masonry.
5. __________ is a very light type of scaffolding and can be used only for the maintenance work such as painting, pointing, whitewashing, etc.
a) Trestle scaffolding
b) Suspended scaffolding
c) Patented scaffolding
d) Needle scaffolding
View Answer
Explanation: In Suspended scaffolding, the working platform is suspended from the roof by means of ropes, wires or chains and arrangements are made such that the platform can be raised or lowered. This type of scaffolding does not create any obstruction on the ground and it is the most effective as it always provides the optimum level for working.
6. In __________ type of scaffolding, the working platform is supported on movable contrivances such as Ladders, tripods, etc., mounted on wheels.
a) Trestle scaffolding
b) Cantilever scaffolding
c) Mason’s scaffolding
d) Bricklayers scaffolding
View Answer
Explanation: Trestle scaffolding is useful for minor repairs on painting work inside the room and the maximum height of to reach this type of scaffolding can be adopted is about 5 metre from the supporting surface.
7. In __________ type of scaffolding, in place of timber, the Steel tubes can be effectively used for the scaffolding work.
a) Steel scaffolding
b) Patented scaffolding
c) Suspended scaffolding
d) Trestle scaffolding
View Answer
Explanation: In steel scaffolding, the Steel tubes are available in standard lens with special coupling and set screws. The scaffolding can be used upto any height. It is strong and more durable; it can be easily irritated and dismantle; it possesses high scrap value and it is resistant to fire.
8. _________ are the vertical members of the framework and they are either supported on the ground or embedded into the ground.
a) Ledgers
b) Standards
c) Putlogs
d) Rakers
View Answer
Explanation: Whereas, Putlogs are the transverse species which are placed on the Ledgers and which are supported on the wall at one end. They are at the right angle to the wall. And the Ledgers are the horizontal members parallel to the wall.
9. ________ is a piece which is used to bridge an opening in a wall and it supports one end of the putlog at the opening.
a) Transoms
b) Braces
c) Rope
d) Bridle
View Answer
Explanation: Whereas, Transoms are the Putlogs, but their both ends are supported on the Ledgers. And, Braces are the diagonals cross species fixed on the standards.
10. _________ is a Board placed parallel to the Ledgers and supported between the Putlogs.
a) Toe board
b) Guard rail
c) Raker
d) Bolts
View Answer
Explanation: Toe board is provided to work as a protective measure on the working platform. Whereas, Guard rail is a rail provided like a Ledger at the working level.
