<p>A method and an apparatus for roofing a structure or the like by erection of at least one frame and installation of a tent cloth (41) therealong. The frame comprises various elements forming, in the erected position of the frame, roof (2) and wall elements. The roof elements adjoin each other along a ridge line (11) and the wall elements adjoin the roof elements along roof edge lines (11). The method and apparatus are characterized in that the frame consists of two frame halves hinged together in a flat starting position and lifted from that position by at least two points. The roof elements are lifted first on the side of the ridge line (11) until the roof elements are at a given angle to each other, in which position there is provided between the roof elements a tie member which, in the loaded condition, defines an angle between the roof elements. After this, the frame is hoisted further, whereby the wall elements swivel outwardly until these have reached a substantially vertical position, in which they are fixed relatively to the roof elements (2).</p> |
