USE FOR FORMWORK RAFT
The purpose of the foundation structures is to minimise deferred deformation due to the irregularity of the ground and asymmetric loads to ensure building stability. It is the two latter aspects that represent the true danger to the integrity of the foundation and the overlying structure. Once the type of foundation that is best suited for distributing the loads in the ground has been identified, based on the characteristics of the building and ground, the problem goes from being technical to economical, therefore the most economic solution must be identified for implementing the selected solution.
A solution to this problem, without changing the type of structure, is to create a box type raft (or formwork). This obtains a honeycomb structure consisting of two flat plates connected by mutually perpendicular beams: lower and upper slabs with a thickness of 15-20 cm with connection beams with a height of 70–120 cm positioned at variable centre distances depending on static requirements. Thanks to the Iglù® or Atlantis formworks from the Daliform Group , in association with L-Plast panels or Muro formwork, it is possible to complete the raft structure in only two phases; that is casting the lower slab on which the Daliform Group products are positioned and then casting the beams and compression slab at the same time. This makes it possible to create extremely rigid foundations at a limited cost.
The main function of the foundation structures, such as the one proposed by the Atlantis System is to distribute the loads from the pillars, plates and walls to the ground and at the same time anchor the building to the ground, guaranteeing its stability. In some cases, always using the Atlantis System, foundation piles can be eliminated, which would instead be necessary with other construction solutions.
USE FOR DEEP, MULTI LEVEL FOUNDATIONS
The Atlantis System makes it possible to adjust the height of the elevator pipes within a centimetre, which can be supplied in different measurements. This will make it easy to quickly create structures at a low cost that require variable heights such as sloping ramps, slabs and multi-level slabs.
Normally, slabs are created at the same height starting from the foundation bays that are on different levels (a classic example are “reversed T” beams or isolated foundations plinth), the Atlantis System makes it possible to easily create these structures without having to interrupt the regular placement of the formworks. The described system, if combined with the Muro formwork accessory, additionally reduces implementation times.
