Principles of Construction - 2

The minimum pitch of a flat roof is:

• 0 degrees

• less than 10 degrees

• less than 15 degrees

• less than 20 degrees

The primary purpose of the cavity in a cavity wall is to:

• reduce the amount of maeirals required by the building

• provide ventilation for the building

• act as a barrier against damp entering the building

• provide increased structural strength to the building

The components that connect the inner and outere skins of a cavity wall are called

• wall ties

• lintels

• returns

• piers

Cavity walls in houses typically consist of:

• an outer skin of blockwork and an inner skin of brickwork

• an outer skin of brickwork and an inner skin of blockwork

• an outer skin of brickwork and an inner steel frame

• an outer skin of blockwork and an inner frame of steelwork

Brick built supports constructed beneath the wall plate on a floating floor are called:

• sleeper walls

• dormer walls

• cavity trays

• lintels

Which of the following are all types of floor construction?

• solid, suspended and floating

• pitched, flat and hipped

• cavity, solid and stud

• strip, pad and raft

The key purpose of a foundation is to:

• provide a flat area for building

• spread the load of the structure

• prevent moisture from entering the building

• stop plants growing beneath the structure

Which material is included in concrete foundation construction to increase its tensile strength?

• cement

• fine aggregate

• coarse aggregate

• steel mesh

The main structural components of a roof that provides the framework are called:

• pitch

• apex

• rafters

• eaves

The load on a strip foundation from a wall is distributed at what angle?

• 45

• 75

• 90

• 120
