Abstract: An arrangement for encasing ceilings with trusses in which a framework of four telescopic supports and strengthened by struts, holds casing beams having two sides on which telescopic ceiling casing carriers are located. The framework provides for supporting the casing for the trusses, and at least two trusses are placed a distance apart and adjacent from each other. Between the casing beams and the supports, beam support carriers are telescoped on both ends and combined into a fixed-angle frame detachably and tension-proof connected to the supports. The support carriers, furthermore, support abutments bridging a space between the casing tables for the truss casing carriers. Four intermediate supports are detachably fastened to the beam support carriers, and the casing beams which support the ceiling casing carriers and which are combined with the ceiling casing carriers into a rigid-angle frame, are fastened to the four intermediate supports.
