FIELD: construction engineering. SUBSTANCE: this can be used in erection of vault-like coverings of buildings. Vault-like structure has framework which is made up of flat trusses with upper horizontal chord and lower vault-creating chord which are connected together at lower chord level by means of beams which are welded to uprights of trusses. Covering is rigidly secured to beams at level of lower chord of trusses. Covering is made up of rod-shaped components located at definite pitch perpendicularly to beams and connected to them in lower part of beams. Rod-shaped components are fixed in place by layer of fine-grain concrete. Secured to bottom side of rod-shaped components are two layers of reinforcing nets which are laid with displacement of their openings and above another net which is used as shuttering. Size of openings in reinforcing net is larger than size of openings in shuttering net by 8-11 times. Size of openings in shuttering net is equal to 0.2-0.4 of size of largest piece of concrete aggregate. Aforesaid embodiment of structure simplifies erection operations and concreting procedure with less materials needed. EFFECT: higher efficiency. 3 dwg
