Systems of structural reinforcement | Ruregold
Ruregold of Laterlite is a leading company in the field of structural reinforcement and has a deep knowledge of the market of construction reconstruction and infrastructure maintenance, thanks to the significant know-how gained in almost 20 years of experience. Ruregold concentrates its energies in the evolution of new systems for the reinforcement of concrete and masonry structures with composites of excellence, in particular the FRCM range with PBO and carbon mesh and inorganic matrix that, first in the world, has obtained the international validation certification. Features The structural reinforcement systems FRCM (Fiber Reinforced Cementitious Matrix) consist of the coupling of a long fiber at high performance and inorganic matrix cementitious stabilized used with the function of adhesive: a step ahead of traditional FRP systems with composite matrix epoxy resins. Two different types of structural fibres, carbon and PBO (polyparafenilenbenzobisoxazole) are used in Ruregold’s FRCM reinforcement systems, both materialists with mechanical properties and performance that can absorb the efforts generated by overloads and exceptional events, such as earthquakes. The range also includes FRP reinforcement systems with carbon fibre pultruse fabrics and sheets and epoxy matrix consisting of the joining of a long high performance mechanical fibre and a matrix acting as an adhesive between the fibres and the support allowing the transfer of stresses from the structure to the fibre. The intervention of plating of the masonry, by means of the technique of the reinforced plaster - CRM system - allows the increase of the carrying and seismic capacityresistant to walls thanks to the use of fibreglass nets and specific mortars for the restoration and consolidation of masonry structures that allow to intervene especially in the case of walls are severely damaged or inconsistent, provided that the necessary transverse connections are in place and are well anchored to the reinforcements on both sides of the masonry. The range is completed with products and solutions for the restoration and preparation of the concrete and masonry support for subsequent structural reinforcement interventions, Fiber-reinforced HPFRC micro-extruders reinforced with steel and synthetic fibres for structural reinforcement of pillars, beams, beam-pillar knots and reinforcement hoods and X Plaster floor coverings.

Thermal acoustic insulation horizontal dividers | Sottofondo Lecazero8
The evolution of modern construction techniques, new regulatory and design requirements determine the continuous evolution of the way of understanding the background as a whole; In fact, from a simple layer to a floor support has arrived at a real constructive element of the building object of careful design and executive care. The existing regulatory framework, Law 447/95, DPCM 5/12/97 and Decree 26/6/2015, introduces the need to design the background package in order to achieve a specific thermal and acoustic performance The lightweight and insulating solutions based on Leca expanded clay allow you to achieve the best performance of thermal and acoustic comfort, ideal even in renovation, reducing loads by up to 75% compared to a traditional solution. The finishing screed, as a direct support of the floor, must always be present and suitable for laying the coating, whatever it may be (ceramic, wood, vinyl, PVC, etc.). Features The screeds of the Lecamix line (Facile, Forte and Fast) and Centrostorico are light and premixed in a sack of CE-marked Lecapiù expanded clay for the construction of floating screeds, ideal for renovation because they do not overload existing floors and structures. The lightened background, that is the layer of thermal insulation/ lightening/ compensation, will have the function of leveling all the dimensions creating the ideal support for the subsequent laying of the acoustic insulation layer to the foot and the screed finish. The undercoats of the Lecacem range (Mini, Classic and Maxi) and Centrostorico are pre-mixed in bag and based on Lecapiù expanded clay, ideal for creating resistant and light compensation layers (from 450 to 600 kg/mc) which contribute significantly to the thermal insulation of the floor.

System of slab consolidation
Negli interventi di ristrutturazione degli edifici in muratura, I solai hanno un ruolo fondamentale per il consolidamento statico e antisismico degli edifici, grazie alla formazione della cerchiatura perimetrale che evita il ribaltamento delle pareti e alla formazione della soletta collaborante interconnessa al solaio esistente che crea un piano rigido. In particolare, l’obiettivo è quello di realizzare interventi tali da ottenere il “comportamento scatolare” del fabbricato esistente. L’efficace collegamento tra i solai e le pareti è indispensabile per assicurare la continuità strutturale degli elementi portanti dell’edificio: al solaio il compito di ridistribuire al meglio le forze orizzontali sulle pareti, formazione del piano rigido, oltre a evitarne il ribaltamento. Caratteristiche La realizzazione di una nuova soletta collaborante leggera, collegata al solaio esistente grazie al contributo dei Connettori CentroStorico Legno, Acciaio, Calcestruzzo, Chimico e alla muratura con Connettore CentroStorico Perimetrale, incrementa la sicurezza antisismica dell’edificio. Inoltre, la nuova soletta collaborante in Calcestruzzo Leca, collegata al solaio e alle pareti esistenti tramite i Connettori CentroStorico e Perimetrale, consente di ridurre il peso gravante sulle strutturesino al 50% rispetto a una soluzione tradizionale. Grazie anche al contributo dei massetti e sottofondi alleggeriti Leca, il sistema assicura positivi effetti sia sulla riduzione delle masse oscillanti durante l’evento sismico che sull’aumento della portata utile del solaio.

Certified systems for radiant floors
Underfloor heating is a technology that consists in placing, under the floor and inside the screed, pipes with the passage of hot water able to transfer heat evenly to the environment. The distribution of heat is homogeneous and by irradiation: the whole surface of the floor gives out heat and the distribution of temperature in the room avoids the stratification upwards, advantage that is amplified in high-rise rooms. Features In underfloor heating systems the radiant screed is an integral part of the plant; it is therefore of fundamental importance to use products with specific performance, both to maximise the thermal performance of the system and to ensure the safety of the flooring over time. The radiant screeds Paris 2.0 and Paris SLIM are the certified solution that allows to maximize the thermal performance of the underfloor heating system, thanks to the high certified conductivity, low thermal inertia and thickness, ideal also in renovation.
