Over the last recent years a greater and greater attention to the existing building heritage and to the activities aimed to the preservation of both buildings with high architectural value and those belonging to the category of traditional buildings has been developed. Especially in reinforcement works, the Bossong company has carried out research on techniques and materials aimed at reinforcing masonry structures, proposing controlled injection anchors with sock for the consolidation of historic buildings, called GBOS.
CHARACTERISTICS The system is composed by a strong element , a high strength stainless steel bar -AISI 304 or AISI 316- (ft nom 750 N/mm2 - fy nom 650 N/mm2 ), with full thread along the entire length. It is provided of a sock with the function of controlling the coaxially carried injection of the grout. These two elements, together with the grout, are fundamental to make integral the reinforcing element to the masonry. Besides allowing good injection operations, avoiding unexpected and often damaging spread of grout in voids and cavity that can be present in the existing walls, the sock guarantees the adherence of the injected material to the substrate throughout its entire length and a homogeneous distribution of stress thanks to both the adherence of injected material and the mechanical interlock that the injected grout develops with masonry. The line of anchors for controlled injection is complete with a range of accessories in AISI 316 stainless steel, couplers, turnbuckles, nuts, to fulfil the different needs of each project; Bossong can provide un-tensioned steel reinforcements, pre-stressed tendons, vertical anchors and anchors with every degree of tilt.
