SISMO Custom Insulated Formwork Block
The basic structure of the SISMO® construction module is the galvanized and stainless steel frame. Filler panels are inserted into the outer walls of the frame, turning it into a closed structure into which concrete can be poured. The type of infill panels used depends on the purpose of the wall: load-bearing or not, insulated or not, etc.
The steel cable frame also acts as a reinforcement and anchoring surface for the finishing material and will hold the reinforcement bars in place during the concrete pouring operation.
The SISMO® Building Module
An ultra-modular system
The SISMO® module offers the architect the freedom to choose from an unlimited number of designs and finishes. Discover below the manufacturing process and the myriad of options offered by the SISMO® solution
The Weft
The basic element of the SISMO concept is a three-dimensional frame made of galvanized and stainless steel cables. This frame fulfills a number of elementary functions. It forms the “body” in which the panels are inserted to create the formwork of the structural material. It also acts as a reinforcement and anchor for the interior or exterior facing.
The choice of frame is determined by the following factors:
• structural requirements
• the type of insert panels;
• the desired finish.
The width of the SISMO weft can range from 6 cm (S6) to 50 cm (S50). Please request our Technical Guidelines Document for a comprehensive list of SISMO modules.
Insert Panels
The insert panels transform the frame into a closed structure. The type of filler material used is determined by the purpose of the wall and the choice of locally available materials.
Choose the right insert panel. The characteristics of the filling material depend on the specific requirements of the building, including:
• thermal insulation
• sound insulation
• fire resistance
• the ability to integrate ducts
• finishing
Insert panel options:
• le polystyrène
• le Neopor®
• mineral wool
• cellular glass
• cardboard
• fiber cement
• the cork
The most common material used to make insert panels is polystyrene. Polystyrene offers significant advantages in terms of design, production and handling on construction sites.
These advantages are:
the absence of thermal bridges since the polystyrene acts as formwork, optimal flexibility in terms of design, particularly easy handling on site given the low weight of the material, easy integration of electrical conduits and piping
Depending on the type of material used, insert panels may have straight edges or tongue and groove edges for easier interlocking.
The Structural Material
The cavity between the insert panels is filled with structural material. The type of strong material used is determined by the purpose of the structure and the choice of locally available materials. High-density concretes are frequently used as well as lightweight concretes. Reinforcements may be added where local building regulations require.
The pouring of concrete is carried out using a pump.
The dimension of the concrete veil will determine the plasticity of the fresh concrete and the maximum size of the aggregates.
