Description

Method for erecting "high concrete structures, e.g. high-rise apartment buildings

It is known that the outer walls of high-rise apartment buildings by means of sliding or climbing formwork in one go from the bottom to manufacture above and then pull in the ceilings in the form of concrete false ceilings. It has been suggested that to produce the ceilings all with the same ceiling formwork, in such a way that with this formwork first the top one Ceiling is poured and then the ceiling formwork gradually descends from this uppermost ceiling and is then poured into concrete the second from the top and lower ceilings is lowered. So, starting with the top one, the ceilings are made of Manufactured from top to bottom one after the other using the same raised and lowered formwork, whereby the ceilings must of course be anchored in the outer walls created by sliding formwork.

For buildings of normal height, the strength of the initially ^v 'is sufficient; ^{:; i} without intermediate ceilings, load-bearing side walls, "'but neither the high-rise buildings that are common today, with up to twenty storeys, nor the very high chimneys, which also have intermediate ceilings to accommodate the fireclay interior lining, can be built in this way.

According to the invention, all the requirements that are placed on high-rise buildings are met. to provide with false ceilings from Pestigkeits- and lertigungsStandpunkt from, are characterized, that the genügty later, a large number _r such as twenty or more floors comprehensive structure into two or more, in each case later by a greater number. Construction sections containing false ceilings is divided and after the first and each subsequent construction section has been erected by means of a ceiling formwork assigned to each construction section, first the uppermost ceiling of the construction section is produced as a stiffening ceiling and then, as is known per se, the intermediate ceilings of the associated construction section located underneath are produced by lowering the respective ceiling formwork will. By drawing in false ceilings after the sliding structure of each section of the enclosing walls, a substantial increase in the rigidity of the sliding structure is achieved during its construction and a corresponding saving in reinforcement material is achieved, but it is also made possible immediately after the insertion of the top ceiling of the first

It surrenders a considerable gain in time because ceilings are being created in several construction phases at the same time using this formwork lowering method « can be-r
