A method of erecting a multi-level building from precast concrete

摘要

The method provides for the erection of the load-bearing basic design of an office or, respectively, input or multifamily house in different construction variations from precast concrete. The invention relates to the erection of a building with a plurality of basement-level in skeleton-solid construction method, wherein the entire static only from precast concrete-elements and for the mounting, only a very short installation time by means of a crane, up to max. 1.5 t lifting force is required.The central to claim of the present invention consists in the arrangement of the free-standing and stackable hollow columnar-concrete prefabricated (1), the threaded rods (6) with one another and are screwed together with connecting members (2) for example, a hexagonal load-bearing floor, as shown in shown clamping.Furthermore, there is in the case of this baukonstruktions system the possibility of the basic hexagonal shape by adding and removing of hollow columnar-elements (1) or connecting members (2) in a predetermined grid pattern to arbitrarily extend adjacent of equilateral triangles. This makes it possible, for example, also the long straight two rows of houses in the case of terraced houses or offers alternation in the building design.A further advantage of this invention, in comparison with conventional process for the erection of mono- or multifamily houses according to the prior art consists in the possibility of a simple and complete decommissioning without destruction of the supporting components or in the re-usability of the betonfertigteilwerk elements after disassembly or for the later expansion. The interior of the stacked hollow columnar-elements can be in the form of inspection, an air conditioning or ventilation shaft can be used and is connected via large openings of each projectile is easily accessible. The individually and subsequently overall outer walls or possible drywall-interior walls have no supporting function and are exchangeable and can be changed at any time without to influence the structure of the building. The closing of the floor between the connecting members (2) can be rotated by 60 ° smaller concrete subcarriers (3) and with concrete slabs (4) (8) (9).
