Abstract

The invention concerns equipment for bricklaying of prefabricated chimneys and comprising a stationary frame construction 2,3,4,6. In order to enable bricklaying of the chimney to be carried out from one and the same position at a convenient working height, without the need to build scaffolding, work on roofs, etc., the frame construction forms a vertical guide 4 for an upward/downward movable operating frame 5 with carrier arrangement 14 for the chimney elements which are to be laid one at a time against the above-lying element or several elements A5-A8 laid together, and raised a vertical distance corresponding to a full element height at each lift. The stationary frame construction is provided with a side frame 6 at a convenient working height above the chimney's lower end. The side frame 6 comprises mainly horizontal slide rails 7 which extend into the area of the upward/downward moving element carrier 14, so that a chimney element A4 which is arranged on the side frame's support surface for the application of mortar onto its upper side, possibly lying on a thin slide plate 8, can be moved along the slide rails 7 to a position where it will lie beneath chimney element A5 or several elements A5-A8 situated above so that, by lowering the element carrier 14, it can be laid together with the said above- situated element or several elements respectively. In this position, the element carrier 14 is arranged so that it can be opened and then lowered alongside the mortar- coated element 4 which has been fed in from the side frame 6. After that, the element carrier 14 is closed beneath the said element A4 and, supporting this element and the above-situated chimney elements already laid together, the carrier 14 is raised a vertical distance corresponding to a full element height, after which the said procedure is repeated until the required chimney height has been attained. <IMAGE>
