FIELD: construction. ^ SUBSTANCE: invention is related to construction and may be used in erection of monolithic multistoried buildings and structures from concrete and reinforced concrete in curb in winter time. Method for erection of monolithic buildings in winter time includes installation of flying form elements onto prepared foundation, concreting, thermal treatment of concrete performed in several stages. Moreover, at the first stage treatment is carried out by means of heat supplied inside the form, and it is continued until concrete gains partial strength, afterwards the form is withdrawn, and at subsequent stages treatment is continued without form. Therefore, tier-like treatment is carried out, when at floor identified by symbol N treatment is executed by heat supplied to form, at lower tier - at floor N-1 - heat is supplied into concreted cell of monolithic building, at even lower tier - at floor N-2 - dosed cooling of concrete is executed either by means of heat loss control or with dosed heat pulses, depending on ambient air temperature, and at a lower tier - at floor N-3 - heat is either not supplied or is supplied depending on performance of other works. ^ EFFECT: reduction of material, labour and power resources consumption. ^ 5 cl, 1 ex, 1 tbl, 1 dwg |
