Interjoist for forming formwork of concrete slab of concrete floor of building, has core integrated with thermal bridge corrector forming element to form transverse and/or longitudinal thermal bridge corrector

摘要

The interjoist has a core (10) whose longitudinal edges are equipped with a support spoiler (11). The core is integrated with a thermal bridge corrector forming element (3) to form a transverse and/or longitudinal thermal bridge corrector. The thermal bridge corrector forming element is mounted in a housing that is formed in the core in a removable manner, where the element and the core are made of different materials. The element is made of insect e.g. termite, repulsive material for inhibiting propagation of fire. An independent claim is also included for a method for manufacturing an interjoist.
