1, cushion template: s =1* 4 * 0.1* 2 = 0.8m2 (circumference x height x quantity)

2. Basic template: S=0.8*4*0.45*2=2.89m2 (perimeter x height x quantity)

3. Foundation column formwork: S = (0.4 * 4 * 0.6-0.4 * 0.3 * 2) * 2 =1.44m2 ((circumference x height-contact area of beam head) x quantity).

4. Beam formwork: S=(0.3+0.4*2)*(4-0.2*2)=3.96m2 ((bottom+side X 2) X clear beam length).

When calculating the slab bottom ribbed beam, the template calculation height of slab bottom ribbed beam is: beam section height-cast-in-place slab height, so the landlord said that 120 should be deducted when calculating the beam template (the deducted height depends on the thickness of cast-in-place slab). It is very important to calculate the total height of the formwork around the cast-in-place slab. For example, the formwork height of the peripheral beam is 0.4m, which is close to the inner side of the beam.

Extended data:

Formwork engineering is a whole set of formwork and supporting formwork structure system formed by newly poured concrete. Among them, the structural part that is in contact with concrete and controls the predetermined size, shape and position is called formwork, and the support system consists of bars, trusses, connectors, metal accessories and working bridges that support and fix the formwork. For sliding formwork, jack-up formwork consists of lifting power, lifting frame and platform. ? Formwork engineering is a temporary structure in concrete construction.
