METHOD FOR RECONSTRUCTION OF BUILDING Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this can be used in reconstruction of long buildings with addition of more storeys. According to method, reconstruction is effected in succession by dividing building into sections and operating section after section. Holes are made in roof of building and elbow-shaped supports are installed in them so that their lower part rests on existing ceiling of upper storey, and lower part is outside building. Supports are installed simultaneously on adjacent sections of building to be reconstructed. Supports are fixed by strut members and guide members are installed on tops of supports. Using guide members as load-bearing parts, tent is erected above selected section. Under protection of tent, old structures of building are dismantled and new structures are erected. After that, tent is moved to next section being reconstructed. Simultaneously with reconstruction of current section, freed temporary support are disassembled and installed on following section of building. Tent and all remaining supports are dismantled on completion of reconstruction operations. EFFECT: high efficiency. 2 dwg
