【 摘 要 】

The article deals with a typical technological map for the installation and dismantling of the formwork of a German manufacturer, the loads listed in the technological map according to the German regulatory documents are considered. The calculation of the loads acting on the formwork was performed in accordance with the Russian regulatory documents. A table comparing the results is presented from which it can be seen that the loads calculated in accordance with DIN 4421 and GOST R 52085-2003 for the same formwork differ in the values obtained. The conclusion is made that it is necessary to apply the Russian normative documents when calculating and using the formwork in the territory of the Russian Federation. In accordance with the Russian regulations, when calculating the distances between girders and contractions, calculations must be made for the two limiting states - from the strength conditions of the shield according to the carrying capacity and the shield strength by deformation. The distances between girders and contractions calculated in this way will meet the requirements of the normative documents of the Russian Federation. The article proposes a method for determining the distances between girders and contractions in two limiting states and shows the derivation of the formulas used in the calculations.
