A BUILDING STRUCTURE ELEMENT AND STIFFENING PLATE ELEMENTS FOR SUCH AN ELEMENT

摘要

A prefabricated, supporting building structure element, such as wall element s (11), floor structures (47) or the like comprising a reinforced concrete sla b (13) having a plurality of discrete, parallel, horizontally separated, not mutually joined, longitudinally extended stiffening plate elements (15), eac h having a web (17) with a first longitudinal edge portion (21) embedded in th e concrete, such that a considerable portion of the web (17) protrudes freely, substantially perpendicularly from a first side defining surface of the concrete slab (13). The building structure element is characterised in that the longitudinal edge portion (21) exhibits a substantially wave shaped corbelling from the plane of the web (17). The invention also relates a stiffening plate element intended for such building structure element.
