BUILDING TECHNOLOGY IN CONSTRUCTION UNIT 6 Bryan Shenton

INTRODUCTION Building technology has evolved over the centuries between simple structures, through to hi-tech, state of the art buildings.

TRADITIONAL TYPE OF MATERIALS BRICKS & MORTAR TIMBER CONCRETE

MODERN MATERIALS USED GLASS PLASTICS PREFABRICATED COMPONENTS

John Fox, College of North West London BUILDING USES HOUSES & FLATS TRADITIONALLY 1 OR 2 STOREY HIGH BUILT FROM BRICK, STONE OR TIMBER ALL HOMES BUILT TO BUILDING REGULATIONS MONITORED BY BUILDING CONTROL February, 2012 John Fox, College of North West London

CRITERIA FOR HOUSE BUILDING STRUCTUALLY SOUND RESISTANT TO MOISTURE THERMAL PERFORMANCE LOAD BEARING SOUND INSULATION ASTHETICALLY PLEASING February, 2012 John Fox, College of North West London

WAREHOUSES & INDUSTRIAL UNITS COMMERCIAL BUILDINGS OPEN SPAN BUILDINGS BUILT IN STEEL FRAMES CLAD WITH ALLUMINIUM ENCLOSED BOTH ECONOMICALLY AND SAFELY February, 2012 John Fox, College of North West London

RETAIL UNITS SHOPS & COMMERCIAL BUILDINGS LARGE OPEN SPAN PORTAL FRAME CAN BE ADAPTED FROM LARGER HOUSES

OFFICES CAN BE LOW OR MULTI STOREY BUILDINGS OPEN PLAN SUB-DIVIDED INTO SMALLER WORKING AREAS MUST INCORPORATE FIRE REGS. EG. FIRE EXITS, ALARMS, SPRINKLERS ETC.

FORMS OF CONSTRUCTION TIMBER FRAME WHAT ARE THE ADVANTAGES OF PREFAB CONSTRUCTION?

TIMBER FRAME BUILDINGS BEEN BUILT IN THE UK SINCE THE 1960’S TIMBER PANELS BUILT IN THE WORKSHOP RATHER THAN IN SITU DELIVERED TO SITE EASY TO ASSEMBLE PRODUCED TO QUALITY CONTROLLED STANDARDS & TOLERANCES

TIMBERFRAME COMPONENTS Building Technology in Construction 19/05/2018 TIMBERFRAME COMPONENTS EXPLAIN THE PURPOSE OF EACH OF THE FOLLOWING COMPONENTS; VAPOUR BARRIER INSULATION QUILT S/S WALL TIE INSULATION MEMBRANE SHEATHING BOARD John Fox, College of North West London

TIMBER FRAME BUILDINGS CROSS SECTION February, 2012 John Fox, College of North West London

TIMBER FRAME CONSTRUCTION TIMBER PANELS ( 100X50MM ) ARE NAILED WITH PLYWOOD SHEETS TO GIVE ADDED STRENGTH THESE PANELS ARE LOAD BEARING AS THEY SUPPORT THE STRUCTURE OF THE ROOF TIMBER STRUCTURE IS ENCLOSED WITH EITHER BRICKWORK OR STONE. THIS IS ALSO KNOWN AS CLADDING

STEEL FRAME CONSTRUCTION LIGHT STEEL FRAME BUILDINGS (SKELETAL) WERE DEVELOPED IN THE 1880’S FOR AMERICAN SKYSCRAPERS USED FOR HOUSE CONSTRUCTION IN THE EARLY 1920’S STEEL BECAME RELATIVELY EXPENSIVE & NOT A VIABLE ALTERNATIVE FOR HOUSING

STEEL FRAME ADVANTAGES FACTORY MADE RELATIVELY EASY & QUICK TO ASSEMBLE UNAFFECTED BY MOISTURE POTENTIAL LONG ROOF SPANS COMPOSITE DESIGN

DISADVANTAGES DEFORMS AT HIGH TEMPERATURE NEEDS TO BE FIRE COATED ELECTRICTY CONDUCTOR- MUST BE EARTHED

CONCRETE FRAME BUILDINGS THIS SYSTEM WAS FIRST DEVELOPED IN THE LATE 19TH CENTURY BY WILLIAM E. WARD THE FIRST CONCRETE FRAME SKYSCRAPER WAS THE INGALLS BUILDING, BUILT IN CINNCINATTI IN1904- 210FT HIGH

CONCRETE FRAME FORMS OF CONSTRUCTION IN SITU- STEEL OR WOODEN FORMWORK IS REQUIRED TO CREATE THE COLUMNS AND BEAMS. CONCRETE IS THEN POURED AND THE SHUTTERING IS REMOVED ONCE THE CONCRETE HAS GAINED ENOUGH STRENGTH. PRE-CAST- PANELS ARE DROPPED IN BY CRANE AND BOLTED TOGETHER TO FORM A RIGID STRUCTURE

ADVANTAGES & DISADVANTAGES OF CONCRETE FRAME CONSTRUCTION Building Technology in Construction 19/05/2018 ADVANTAGES & DISADVANTAGES OF CONCRETE FRAME CONSTRUCTION ADVANTAGES- IN-BUILT FIRE PROTECTION MOULDED INTO ANY SHAPE HIGH STRENGTH IN COMPRESSION DO NOT REQUIRE A SECONDARY FINISH DISADVANTAGES-CRAINAGE REQUIRED REQUIRES INITIAL SUPPORT SKILLED WORKFORCE REQUIRED TO ASSEMBLE John Fox, College of North West London
