O-SHAPED BENCH FOR THE IMPROVEMENT OF URBAN SPACES, MADE ON A 3D PRINTER

摘要

The utility model relates to the field of construction and can be used in the manufacture of building products in the form of small architectural forms for the improvement of urban spaces - parks, squares, streets, etc. The task of the utility model is to create a bench structure with a reduced labor intensity of its manufacture, exclusion of overspending of materials , with increased crack resistance, impact strength and the possibility of its manufacture on any construction 3D-printers. The task is achieved by the fact that the bench, which includes a seat made of longitudinal elements, perforated crossbars installed on a rigid frame, characterized in that the rigid frame is made in the form of a volumetric element, including supports and a spacer bar with through mounting holes for fastening the longitudinal elements of the seat, while the rigid frame is made on a 3D printer as a single monolithic fiber-reinforced concrete O-shaped element, the longitudinal elements of the seat are made of wood-polymer mposite, perforated crossbars are made of a square profile with through mounting holes in the bottom wall, the connection of the longitudinal elements of the seat with perforated crossbars is made through the corners with self-tapping screws, the connection of perforated crossbars and a rigid frame is made of galvanized bolts and nuts. The technical result of the utility model is to reduce the labor intensity manufacturing, eliminating overspending of materials, increasing crack resistance, impact strength and the possibility of manufacturing a bench on any construction 3D printers. Thus, the proposed solution allows you to obtain a bench on a construction 3D printer with reduced labor intensity while ensuring quality and saving materials.
