FIELD: construction, road engineering. ^ SUBSTANCE: invention relates to the field of construction, in particular, to a frame of a rapidly erected structure and to the method of its assembly. The structure frame comprises hingedly joined elements of an arch and frame structure. Stands with crossbars, cross braces with crossbars and stands are hingedly joined. The frame comprises central and support hinged joints. The frame is made with rotary hinged joints in a crossbar between the stand and the adjoining cross brace, and also within the length of the cross brace. Sections of cross braces adjoining the crossbar are rigidly connected to it so that together with elements of the stand and the crossbar they form a cell of a convex four-link mechanism. Geometry of the mechanism makes it possible for the structure to rest against the site with hinged joints of cross braces prior to assembly. At the same time the central hinged joint is located above support hinged joints. ^ EFFECT: reduced labour intensiveness and simple erection. ^ 5 cl, 12 dwg |
