Abstract
Reinforced masonry has been subject to research and investigation in Spain for over 20 years now. This paper presents a new contribution within the AllWall system, referred to as the Halfen-Allwall support (Pi-Bracket). This support being regularly spaced every 6m to form a “braced arch“ effect and provide reinforced masonry. This line of investigation has been made possible through the industrial development of a new patented invention under the trade name Halfen-Allwall Pi-Brackets in combination with Murfor brickwork reinforcement.
This combination provides a new way of supporting external walls at fixed points coinciding with the verticals of the structural supports. The system prevents the loading of slabs which, in addition to providing great economy in construction, inhibits cracking due to structural deformation at the support base of the wall and also allows the continuation of insulation and ventilation throughout the cavity.
