Formwork, reinForcement, & ScaFFolding

SCAFFOLDING

by Alexander Chung Siang Yee

The temporary structure required to support newly placed concrete, including the forms and all necessary supporting members, bracing, and hardware. Boarding or sheeting of wood, metal, plastic, or fiberglass for containing and giving a desired shape to newly placed concrete until it sets and gains sufficient strength to be self-supporting. Then it will be removed to be reuse in most cases.

Type of formwork.The formwork appication we've found on our site are woodform work and metal (aluminium) formwork. this is an application of system formwork

Aluminium formwork wall panel

• The formwork is specifically designed to allow rapid construction on all types of architectural layout.

• ToTal system forms the complete concrete structure.• Custom designed to suit project requirements.• Unsurpassed construction speed.• high quality finish.• cost effective.• panels can be reused up to 300 times.• erected using unskilled labour.• environmental friendlier than other systems.• higher cost compared to timber formwork.• require sepcial tools to assemble and dissemble

Supplier: MPE FORMWORK TECHNOLOGY SDN. BHD.

wood formwork wall panel

• easier to handle due to its light weight.• Custom designed to suit project requirements.• an aesthetically pleasing architectural effect can be achieved.• lower initial cost than steel formwork• higher availbility.• panels can be reused up to 3-5 times. with treatment such as paint and oil.• highly depending on the quility and treatment to the wood.• erected using unskilled labour • it requires no special tools..

BATTENPLYWOOD FORMS CAN BE SMOOTH, OR BE SANDBLASTED OR WIREBRUSHED TO ACCEN-TUATE THE GRAIN PATTERN OF THE FACE PLY. PICTURE BELOW IS AN EXAMPLE OF THE APPLI-CATION.

Formtieformtie are required to keep form spreading under the fluid pressure of newly places concrete. while various property fomrs are available, there are two basic type snap ties and she bolts, but only snap ties are used in this site.

Snap ties it has notches or crimps that allow their ends to be snapped off below the concrete surface after stripping of the forms. either cones or washers are used to main-tain the correct wall thickness

Small, truncated cone of wood, steel, or plastic, attached to form tiesto space and spread wall forms, leave a neatly finished depression in the concrete sur-face to be filled or left expose

SCAFFOLDING


INSTALLATION:A WALL PANEL ARE SET VERTICALLY. THEN, A BOLT ARE INSERTED THROUGH AN OPENING TO A WALL TIE OR BRACE STIRRUP WHICH IS ALLIGN ON THE OTHER END; A STUD WILL SLOT INTO THE OPENING ON THE BOLT TO LOCK THE STUD PIN. THIS METHOD WILL REPEAT UNTIL THE WALL ARE SET INTO THE DESIRED SHAPE.

STUD PINIT IS INSERTED INTO THE BRACING BRACCING STIRRUP TO LINK WALL PANEL TOGETHER.

WALL TIE/BRACE STIR-RUPIT IS INSERTED INTO THE BRACING BRACCING STIRRUP TO LINK WALL PANEL TOGETHER.

SCAFFOLDING


in a reinforced concrete, steel bars/rebars resist tensile forces and shear while concrete resists compression force. there are 2 types of rebar: plain or deformed. deformation improve the bond between steel and concrete.

DOWELSIT IS TIES TO A COLUMN TO SUPPORT BEAM AND SLAB. IT IS ALSO USED TO EXTEND OVERLAP VERTICAL BAR EXTEND DOWN INTO FOOTIG OR PILE CAP FAR ENOUGH TO DEVELOP ADEQUATE LENGTH FOR ANCHORAGE.

LATERAL TIESLATERAL REINFOREMENT RE-STRAINS THE VERTICAL REIN-FORCEMENT AND STRENGTHENS THE COLUMN AGAINST BUCK-LING. IMAGE BELOW SHOW THE APPLICATION.

MILD STEEL REBARIT HAS MANY APPLICATION INSIDE A CONSTRUCTION SIDE. IT IS OF-TEN USED IN CONSTRUCTING A COLUMN AND DEFORM INTO DESIRED SHAPE FOR OTHER US-AGE. THE FOLLOWING IMAGE ARE SOME OF THE APPLICATIONS.

BAR BENDING MACHINEIT IS USED TO BEND THE REBAR ACCORDING TO SPECIFICATIONS.

SCAFFOLDING


scaffolding is a temporary structure or platform for supporting workers and materials at a height above the floor or ground duriong the construction or repair of a building. also called staging. it also support construction activirties like concreting, formwork installation. besides, it is set to temporary structures such as rubbish chute, catch platform, walk way, safety net etc.

LGITH SCAFFOLDINGIT IS COMMONLY USED IN THIS SITE.PICTURE ON THE RIGHT SHOWS A SERIES OF SCAFFOLD ARE SUPPORTING WALKING BOARD FOR WORKERS TO WORK ABOVE GROUND LEVEL.

WORKERS ARE TRYING TO HOIST UP THE VERTICAL FRAME FROM GROUND LEVEL TO LEVEL ABOVE.

FALSEWORKTHE TEMPORARY FRAMWORK FOR SUPPORTING A STRUCTURE UNDER CONSTRUCTION THAT IS NOT YET CAPABLE OF SUPPORTING IT-SELF. IN THIS CASE, SCAFFOLDING ARE USED AS SUPPORTING MEMBER. THE SCAFFOLDING WILL BE REMOVE ONCE THE STRUCTURE HAS GAIN ENOUGH STREGHT TO SELF-SUPPORT.
