FIELD: ferroconcrete construction. SUBSTANCE: form has base 1, walls 2 and supports 3 fixed on the base. The walls are provided with locks 5. The support area of supports 7 is tilted in a direction contrary to the support base fixed on the form base. The forks of the supports have different height, which constitutes 0.06-0.4 of the distance between the fork axes. EFFECT: simplified design and process of fabrication. |
