SIMPLIFICATION OF THE REINFORCED CONCRETE ARCHED ROOFING CONSTRUCTION

Irakli Kvaraia, Ioseb Giorgobiani

Abstract


In this paper, we discuss issues arising in the construction of cast-in-situ reinforced concrete arched roofs and ways to simplify their design. Despite the versatility of existing mold systems in construction, shell-type roofing structures are entirely different from other structural elements widely used in construction practice in terms of their outline and overall dimensions. Therefore, to erect them, it is necessary to build an individual mold system, which would provide the appropriate spatial shape for cast-in-situ reinforced concrete roofing. Due to the scale of shell roofs, the installation of such mold systems is often associated with significant difficulties as it requires a large, bulky structure above the ground surface with the use of load-bearing scaffolding and planking. This results in issues of building individual elements and the entire mold system and accurately placing them in the design position, which can be solved quite easily using the experience gained from similar works. As a demonstration of this, an example of the arched roof construction for the church named after the Mother of God of Iveria, the second largest church in Georgia, was given a few years ago. At the time, the main difficulty was manufacturing and installing wooden arch molds, which was quickly overcome due to considering several practical measures in advance.
