FULL AND SANDWICH WALLS BASIC BEAMS

Solid and sandwich walls as well as foundation beams are prefabricated reinforced concrete elements designed for fast and accurate construction of ground structures in civil, residential, industrial and agricultural construction. Wall units can be designed as full reinforced concrete (bearing / not wearable) or as three-layer sandwich walls (carrier layer + heat insulation + outer protective layer). The foundation beams serve as horizontal load-bearing elements, which transfer the load to the substructure and form a stable foundation for the structural system of the building.

Materials and construction

Solid reinforced concrete walls:

• Monolithic nature of the prefab, high load capacity, stiffness and durability
• Suitable for covering halls, stiffening walls, dividers, fireproof / anti-dust walls, etc.

Sandwich walls:

• Three-layer composition: carrier layer + heat insulation + protective (facade) layer
• The layers are interconnected stainless steel special clips/anchors (minimization of thermal bridges, long life)
• Isolation: ordinary EPS or XPS according to project requirements

Foundation beams / thresholds:

• Bearing horizontal elements for skeleton structures, often as plain beams between footings/piles
• Depending on the project, they can also be with a sandwich solution (e.g. thermal partition at peripheral parts)

Dimensions and parameters (approximately according to the project)

• Foundation beams: length up to approx 18 m, width up to 60 cm, height up to 120 cm

• Wall panels: length usually up to approx 10 m (according to transport and assembly), thickness according to design, height by floor (approximately up to 3,3 m)

• Production is mostly atypical – shape, thickness, reinforcement, openings and details are designed individually according to statics and drawing documentation.

Implementation and assembly

• Assembly of parts is in progress by crane on the prepared structure (basics, feet, ceiling construction).

• Wall anchoring is usually solved using anchor plates, which after fitting each other boils, possibly other system elements according to the project.

• For beams/sills, anchoring is possible, e.g. already contact pins, anchor plates, possibly using system anchoring elements.

• Can be integrated into elements penetrations, installation box, embedded elements, locksmith products and special anchors / mounting elements (e.g. HTU, HTA as needed).

Use:

Wall panels:

• Cladding of halls and industrial buildings

• Stiffening skeleton walls, dividing and fire walls

• Basement walls, technological and operational objects

• Rapid construction of residential and civil buildings (bearing and non-bearing walls)

Foundation beams / thresholds:

• Load transfer between footings/piles

• Supporting structure for perimeter skins and internal stiffening walls

• Protective / anti-impact elements in operational and storage halls

• Peripheral elements of the structure with the possibility of thermal separation

Certification and quality

Design of shape and reinforcement is always solved static calculation for a specific project

Production in a controlled quality system 9001:2015 and according to the relevant ČSN/EN for prefabricated concrete parts
