Recomendations of scafolding fixing on masonry brick walls

Abstract

There are many rehabilitation works that involve the maintenance of the building enclosure, usually made up of faced or cladded masonry brick walls [3]. To this end, it is necessary to attach a scaffolding structure to the façade wall that facilitates the access along the complete external surface of the building. These scaffolds are an efficient system, however the safety they provide is only achieved if it is possible to keep enough stability between its elements and the wall which it is subject to. Current market offers a wide range of fixing solutions. They range from mechanical connections, with different types of plugs and anchors, to chemical solutions. But, as there is no regulation governing the distribution and disposition, the choice of system and its placement depends mostly, among many other factors, on criteria based on the tradition and the previous experience of the companies dedicated to carry out these connections. At present, it is frequent the use of point anchoring systems using mechanical devices. The fastening is solved by a sleeve made of polyamide and a steel eyebolt embedded in it. The anchorage length is clearly marked on the plug and external end flange prevents the plug from sliding inside masonry element.
