FIELD: construction engineering. SUBSTANCE: this relates to net-like arch structure and to its assembly by means of joints with inserts and hooks. Arch structure is formed of multiplicity of parallel curved frameworks. These curved frameworks with butt joints are connected in length by means of several straight rods and butt joints. Straight rods are connected in line at right angles with curved frameworks, thus creating trusses. Curved frameworks include curved rods and braces. Curved rods are coupled to form curved frameworks by means of braces and butt joints. Bracing members are used between curved frameworks and trusses. Description of invention offers several versions of assembling arch structure without using high-rise operations. Aforesaid arrangement of arch structure allows for reducing labour input at assembling and disassembling operations. EFFECT: higher efficiency. 18 cl, 19 dwg
