Trusses are steel-framed support systems used in suspended concrete slabs to prevent deformation and provide stability. They consist of three strain bars held in shape by welded support systems and are integrated into concrete beam planks with hollow blocks. A mesh cladding reinforces the support system.
A truss is a steel framed support system placed atop the truss board between each run of hollow block sub-floor system for concrete slab formations. The triangular shape of the truss girder provides stability to the slab system between the block structures. It also provides a means of preventing movement throughout the slab design.
These beams are primarily used in suspended concrete slabs due to their ability to provide a full span of support for the slab. They prevent any type of deformation of the slab due to displacement which is also not permitted. While there are many different components in these types of concrete flooring systems, the truss is one of the most important factors in slab stability.
Truss girder construction is commonly composed of three different strain bars running longitudinally across the span of the slab. These are held in shape by electrically welded support systems welded to each longitudinal bar within one foot (30 cm) of each other across the entire span of the truss girder. This shape and welded construction allows the truss system to provide an ample amount of tensile strength and strength to resist force from any direction.
The concrete floor system is a basic design for a complex system. The studs on which the slab rests provide vertical support for the beams that span the distance of the floor from the exterior wall to the exterior wall. The truss beam planks are run perpendicular through the proprietary beams that support them. They are spaced according to the distance from the exterior wall to the exterior wall, with the trusses integrated into the concrete beam planks.
Between the planks of the beam and suspended from the planks themselves are hollow blocks. These blocks can be made from a number of different materials as long as they comply with building codes. The hollow blocks are chamfered which allows the trusses to rise between the chamfers to create a W formation into which wet concrete is poured to create a seamless joint between the boards, beams and blocks within the insole.
Once the beams have been incorporated into the block system, the surface is covered with a mesh cladding. The lining acts as a reinforcement for the support of the insole. This mesh reinforcement is designed to allow the finished slab to sit firmly on top of the block and beam support system.
