economy- economic to build

21
Q

Four main functions of a ground floor

A

Provide a safe platform
Transmi live loads and small dead loads (partitions)
Prevent damp
Provide thermal insulation

22
Q

What does a DPC do

A

Prevent rtacking across an open gap

23
Q

Types of floor builidng

A

Hollow and solid

24
Q

Disadvantages of masonry cavity

A

if brick and block used as the outer skin, it can only support itself
there is a limit to the thermal insulation provided by two skins of brick and block material

25
Q

Functions of external walls

A

Carry the load of the upper floors and roof
Act as a weather shield
Provide thermal insulation
Provide a fire resistant barrier
Provide an acoustic barrier to and from the interior
Provide a security screen for the occupants and their belongings

26
Q

How high are DPC’s needed above ground

A

Minimum of 150mm. Below this level and the bricks are susceptible to damp and saturation

27
Q

Requirements of cavity ties

A

To provide a nominal bond between two skins of brick or blockwork
To prevent moisture tracking across the bridge from the outside skin or inner skin

28
Q

How can using a timber frame save in energy requirements

A

Achieve and surpass current insulation standards
Sustainable timber supplies may be used
External finishes other than brick may be considered

29
Q

Varieties of floor construction

A

Precast concrete planks
Concrete beam and block
Timber Composite beam
Timber with metal lattice beam

30
