ALL WEATHER TYPE BUILDING METHOD OF BUILDING

PURPOSE:To provide building method for executing construction of building from a pit excavation work extending over a foundation work and a building frame construction work on the ground and the underground under all weather type environment perfectly independent of the weather. CONSTITUTION:Necessary number of masts 1 of tower cranes provided with self climbing mechanisms 2 are standingly provided on the peripheral part positions of a building 4 to be built. In the self climbing mechanisms 2, a receiving beam 17 is laid between ones arranged in the between beams direction and a receiving beam 22 in the girder direction is laid on both end parts of the receiving beams, a roof frame 24 is assembled on the receiving beam 22, and a roof sheet 25 is put on the roof surface so as to construct a temporary roof 3. The self climbing mechanism 2 is driven so as to elevatably move the temporary roof 3 along the mast 1 and cover a workshop directly thereunder, and construction of the building is promoted under the all weather type environment. All the processes and equipments are depended on the past general purpose technique without technical speciality, and hence execution of construction of various sorts of building becomes easy.
