8
STRUCTURAL STEEL
•
•
•
•
•
High number of design options
•
Large shopping centres, sports centres
and multi-storey offices.
Skeletal framework often complex
Loads carried by beams
Structure is covered by cladding
Large use of glass, polycarbonate and
plastic

STRUCTURAL STEEL
Roof spans between main beams
Main beams
Tie Beam
Secondary beam
Stanchions

10
REINFORCED CONCRETE
•
Alternative to steel frame
•
Columns support beams on which are laid
slab flooring sections
•
Columns, beams and slabs integrally cast
to form a monolithic structure
•
Two common methods of construction.
Lincolnshire Fire and Rescue’s Training Centre
11
REINFORCED CONCRETE(1)
Pre cast reinforced concrete frame
•
Factory produced frame components
•
Transported for assembly on site
•
Similar techniques to steel frame.
Lincolnshire Fire and Rescue’s Training Centre
12
REINFORCED CONCRETE(2)
Composite construction
•
Utilises the advantages of modern
lightweight structural steelwork
•
‘Marriage’ between steelwork & pre cast
concrete columns.

MODULAR STRUCTURES
•
Pre fabricated components
•
High design flexibility
•
Specially designed connectors
•
Encased in concrete to provide a degree
of fire and corrosion protection.

21
HINGED DOORS
•
Most commonly found type
•
All close against a rebate on the door
jamb
•
Four commonly found types
Flush
Panelled
Ledged
Metal
Lincolnshire Fire and Rescue’s Training Centre
22
SWING DOORS
•
Pin hinges allow door to swing in any
direction
•
Door jamb not fitted with a rebate
•
Often partially glazed using wired glass or
copper glazing bars
•
Found in restaurants, department stores and
hotels.
Lincolnshire Fire and Rescue’s Training Centre
23
REVOLVING DOORS
•
Present an obstruction to firefighting
operations unless dealt with
•
Usually 4 or 2 ‘wings’
•
Designed to be collapsed down
•
Essential they are used in conjunction with
a hinged door.
Lincolnshire Fire and Rescue’s Training Centre
24
SLIDING DOORS
•
Solid or lattice construction
•
Widely used in commercial buildings
•
Can slide on one or both sides of an
opening or into a central recess
•
Lattice type usually for security or to
protect an area such as a lift or lift shaft.
Lincolnshire Fire and Rescue’s Training Centre
25
FOLDING DOORS
•
Usually lightweight construction
•
Similar in design to hinged doors
•
Two or more leaves hinged together
•
Whole door opens to one side only
•
Often used to separate two rooms.
Lincolnshire Fire and Rescue’s Training Centre
26
CANTILEVER DOORS
•
Door is counter balanced and pivoted so it
rises upwards
•
Lies horizontal when open
•
Generally fits flush to the opening when
closed
•
Usually found on garages.
Lincolnshire Fire and Rescue’s Training Centre
27
ROLLER SHUTTERS
•
Nearly always made of steel
•
Small examples can be raised by hand
•
Large examples usually operated by
means of gearing and handle or chain and
block
•
Usually found on commercial premises.
Lincolnshire Fire and Rescue’s Training Centre
28
FIRE DOORS
A standard fire door will:
•
•
Serve to contain the outbreak of fire
•
A closed door restricts oxygen movement,
thus helping to starve the fire
Restrict the spread of fire gases into
otherwise unaffected parts of the building
Lincolnshire Fire and Rescue’s Training Centre
29
WINDOWS
•
Allow natural light into a building
•
Serve to provide ventilation to rooms
•
Generally two types, referred to according
to the method of opening
Casement
Sash
Lincolnshire Fire and Rescue’s Training Centre
30
CASEMENT WINDOWS
•
The simplest form consists of a
rectangular frame with the casement
hung on it
•
When more than one casement can be
opened it is referred to as a 2,3 or 4 light
casement.

32
SASH WINDOWS
•
Pivoted sash - opening part supported by
pivots at each side of opening part of
window or top and bottom
•
The term ‘SASH’ refers to the opening
portion and includes the glass and the
surround
•
Partially inside and outside of opening
when open.
Lincolnshire Fire and Rescue’s Training Centre
33
SASH WINDOWS
Sliding sash windows
• Slide vertically
• Double hung is the common form of this
type of sash, both sashes slide vertically in
the frame
• Another type consists of two sashes, one
or both of which can be opened horizontally
