Formwork Systems Wall Formwork Systems H20 -Plywood Wall Form Figure 4 – Timber Formwork H20Plywood has simple design and planning. It provide dimensional variability, soit is easily accommodated to different projects. It allows working with othertypes of form together. The systemcomes with H20 timber beam (Figure 4) and steelwaling as stiffener and the surface is plywood. This combination reduces theweight of the panels. System can carry up to 50 kN/m2 of concretepressure. Panels can be installed horizontally, vertically and the corners withsimple details.
Steel WallForm Itprovides excellent concrete surfaces. It reduces finishing works and relatedlabour costs. Lightersteel wall form system has a capacity to resist 60 kN/m2 concretepressure. It is verydurable and it can easily used for any concrete wall and shaft construction. Figure 5 – Steel Formwork Steelwall form system (Figure 5) can reachany dimensions by using standard panels with filler or extension panels.
Itssteel nature provides durability and enable the form to be reused for severalprojects. Common thread to this two wall formsystems can also be usedas single-sided wall form for structures such as retaining walls, foundationwalls, dam walls by the help of special components which eliminates the need offixation by tie-rods. Column Formwork Systems Figure 6 – Steel Formwork SteelColumn Form This formhas excellent quality of concrete surfaces and it requires no extra repair. It canerect and strip easily, also it reduces labour costs.SteelColumn Form (Figure 6) isadjustable for various cross sections. It reduces projects cost by castingdifferent columns with same formwork. Standardsteel column form can cast rectangular sections from 300×300 to 1000×1000 mm,at every 50 mm increment.
There are two types of column forms with maximumadmissible concrete pressure of 80 kN/m2 and 100 kN/m2respectively. Forms can come in modular panels or single panel in accordancewith the height of the structure. Circularcolumn form system is supplied as two half-circle panels. This makes on-siteerection and stripping very fast. Concrete pressure capacity can be up to 100kN/m2.
H20 -Plywood Column Form Figure 7 – Timber Formwork Ithas adjustable waling whereby casting of columns up to 1200 mm width with. Itsmaximum concrete pressure of 100 kN/m2. It has simpledetails corner fixation. Thesecolumn forms offer similar features as H20/plywood wall forms (Figure 7). The System isquick to erect and allows fast casting of concrete. Easy handling, simpleplanning and quick production on-site are other advantages of the system. SlabForms Systems Figure 8 – H-Type Scaffolding with GT 24 H-Type Scaffolding System H type scaffoldingsystem (Figure 8) has thesespecialities: easy storage, transportation and erection.
It offer high loadbearing capacity. It is alsomulti-purpose system which can be used as working scaffold or table form. The rapidsystem is economical and safe. It can be used as access scaffold, slab shoringsystem. As it hasa high loading capacity and safe connection details, H type scaffolding issuitable to high shoring applications. Byinstalling stairs and large landings in the standard frame, it can become avery safe access tool suitable to all height.
The system can be telescopicvertically. Wooden Products Figure 10 – GT24 Timber Beam Figure 9 – H20 Timber Beams H20Timber Beamscan be used as main support and secondary girder for all concrete formwork.It’s a durable, light weight (5kg/m) and flexible. Standard dimensions of 2.45,2.
90, 3.30, 3.60, 3.90, 4.90 and 5.90 m are available. Special lengths up to 12m are produced up on request.
Thedurability and load carrying capacity of the GT 24 (Figure 10) has been found tomeet the needs of both palatal and wall molds compared to other 20 cm formbeams, smaller beams, steel dikes. Figure 11 – Plywoods PlywoodShuttering Panels are strong, rigid and carefully finished film-facedpanels have ultimate lifetime. They are available in various thicknesses andcombinations. Load Bearing System Elements Figure 12 – Column Column The column(Figure 12) is thevertical structural elements in the load bearing system. Theytransfer forces, such as moment or shear force, which are formed from externaland internal effects to the foundation and the ground. The mainpurpose of the columns is supporting the structure.
Figure 13 – Shear Wall Shear Wall The longside of the shear walls (Figure 13) is atleast 7 times the short edge of the column. Themoments of inertia in the long side direction are much larger and effectivelycarry the horizontal loads in the long side direction. They areusually use to increase the stiffness and strength of structures over 25 metersin height and to limit lateral displacements. Beam Figure 14 – Beams (without concrete) Itis a horizontal load bearing that transfers the loads on a slab to a verticalload bearing such as a wall or a column. It must be durable for bending. Also, beam(Figure 14) is theelements that transfer the loads from the upholstery and other beams to thecolumns or to the load bearing system.
