FIELD: construction.SUBSTANCE: demountable arched structure includes a covering consisting of arches connected with longitudinal edges to each other in overlapped manner; each of the arches is composite as to length and consists of several shaped members. Some part of the shaped members is straight-line, and the other part is arc-shaped except for their end sections that are straight-line. The attachment point of the shaped member to the foundation includes a base from an angle section, on which gusset plates with contact planes for connection to the shaped member are installed in a row, which are supported from the horizontal flange of the base and connected to its vertical flange by means of bends formed on sides from the contact planes. The shaped member is installed so that it is supported from the horizontal flange of the base between the contact planes of adjacent gusset plates and the vertical flange of the base.EFFECT: increasing stability of an arched structure.9 cl, 15 dwg |
