Gable spatial core structures of flat roofs of residential buildings of typical development
This article discusses the features of the pitched roof for typical residential buildings. The design of gable space-roof structures is carried out within the framework of the application of the constructive system of coverage of panel residential buildings with longitudinal load-bearing walls. The formation of the structural form of the cover is solved by the sequential development of the modular system of blocks. The modular system is based on the regular block, which consists of a double-slope deck of bent sheet profiles, fused by folded joints, and a supporting spatial-rod load-bearing system. The design and calculation provisions for the modular unit are presented, taking into account the peculiarities of the layout of the structural form of the cover. The main findings on the use of double-slope roofs are given. The conclusion gives the prospects for the development of the double-slope roofs with the deck of the bent sheet thin-walled profiles. The use of lightweight structure of the roof allows to expand the possibilities of designing the reconstruction of residential buildings of typical construction with a shallow sloping roof without a significant increase in the load on the foundation. The structural solution makes it possible to implement at the construction site an enlarged assembly of the gable roofing, minimizing the use of multiple hand labor and increasing the safety of construction work.
