Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure.
Formwork (shuttering) for a pile cap. A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation.
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials ...
Crane-Climbing formwork: The working platform and the formwork are a unit. Climbing formwork (crane-climbing): in this type of climbing formwork, the formwork around the structure is displaced upwards with the help of one or more cranes [4] once the hardening of the concrete has proceeded far enough. This may entail lifting the whole section ...
Formwork is used in concrete construction as the frame for a structure in which fresh concrete is poured to then harden and take on the desired shape. [6] Aesthetic of concrete surfaces can be varied with different formwork sheathing (e.g. board shuttering, smooth formwork, form liner, form moulds, filter fleeces). The type of material used to ...
For a ground-bearing slab, the formwork may consist only of side walls pushed into the ground. For a suspended slab, the formwork is shaped like a tray, often supported by a temporary scaffold until the concrete sets. The formwork is commonly built from wooden planks and boards, plastic, or steel.
This provided them with a strong material for bulk walling. They used brick or stone to build the outer skins of the wall and then filled the cavity with massive amounts of concrete, effectively using the brickwork as permanent shuttering (formwork). Later they used wooden shuttering that was removed for the concrete to cure.
CPF liners are secured in place on vertical or inclined surfaces with staples or other fixing devices, having first been tensioned onto the formwork shuttering. Once attached, concreting is performed in the normal way. Release agents are not required as CPF liners easily debond from the concrete during formwork striking.
