The construction of the Great Mosque in Algeria is coming to an end. The final stage is connected with the covering of the dome, which is located directly above the Prayer Hall "Juma el-Jazer".
Height 26 meters, diameter 51 meters - this is only a part of the parameters, which emphasize the impressive structure. The base of the dome is 44 meters above ground level (the absolute height of the dome is 70 meters) - a true giant in a golden robe, resting regally on the capitals of the columns of the Prayer Hall.
The structural steel "skeleton" consists of a series of intersecting 8 semi-arches arranged perpendicular to each other. The shell of the arches themselves has 21 segments of 5 different geometric shapes. To cover 4000 sq.m. In the metal construction of the dome, two types of materials were used: glass at the base (1000 sq.m.) and aluminum to cover the remaining 3000 sq.m.
The complete watertightness of the aluminum roof is guaranteed by the Riverclack® system in the exclusive “Graceful Gold” finish. In the near future, decorative elements made of fiber cement will be installed on the roof with the help of special supports. The spherical dome shape required the innovative Rivercalck® Sihouette Roofing Patterns, specially designed to overcome the challenges of double curvature.
During the design process, apart from the roofing cake, Iscom Spa was tasked with developing a number of other solutions, including the location of the gutter at the glazed surface and the organization of the roof outlet directly from the spire at the top of the dome.
During the development of the project, Iscom Spa's technical department worked closely with the Contec Group to supervise every detail.
