Ultra-high performance fibred concrete elongated structural element e.g. frame, for manufacturing e.g. covering element, has two sections with faces extended along longitudinal direction, and surface bond extended between faces

摘要

The element (100) has two sections (10a, 10b) e.g. plates, that are provided with pretensioning units (14a, 14b) along a longitudinal direction (L), where the sections are fixed laterally with each other. The sections have faces (15a, 15b) extended along the longitudinal direction, and a surface bond is extended between the faces. A bond layer is provided in the surface bond. The bond layer has a glue joint (20) that is extended between two faces. An independent claim is also included for method for manufacturing an ultra-high performance fibred concrete structural element.
