Description

Изобретение относитс  к монтажным работам , в частности к способам монтажа стреловыми кранами верхних частей вертикальных копст-рукцин. Известны способы монтажа стреловыми кранами верхних частей вертикальных конструкций , например верхних секций дымовых труб, на предварительно смонтированных нижних секци х. Целью изобретени   вл етс  возможность использовани  при монтаже стреловых кранов с недостаточной высотой подъема крюка. Цель достигаетс  тем, что к верхней секции дымовой трубы на уровне ниже ее центра т жести закрепл ют кронштейн, на свободном конце кронштейна устанавливают противовес, строп т крюк крана за кронштейн в точке равновеси  верхней секции и противовеса, после чего монтируют верхнюю секцию и демонтируют кронштейн с противовесом. На чертеже показана схема реализации предлагаемого способа монтажа верхней секции дымовой трубы.. К верхней секции / дымовой трубы 2 на уровне ниже ее центра т жести закрепл ют кронштейн 3. На свободном конце кронштейна 3 устанавливают притивовес 4. Крюк 5 крана 6 строп т за кронштейн 3 в расчетной точке равновеси  противовеса 4 и верхней секции / дымовой трубы 2 и осуществл ют монтаж верхней секции / на предварительно смонтированных секци х трубы 2. После установки верхней секции / кронштейн 3 с противовесом; 4 демонтируетс . Предмет изобретени  Способ .монтажа стреловыми кранами верхних частей вертикальных 1конструкций, нВПример верхних секций дымовых труб, на пред-; варительно смонтированных нижних секци х, отличающийс  тем, что, с целью использовани  при монтаже стреловых кранов с недостаточной высотой подъема крюка, к верхней секции дымовой трубы на уровне ниже ее центра т жести закрепл ют кронштейн, на свободном конце кронштейна устанавливают противовес, строп т крюк крана за крон-, ш.тейн в точке равновеси  верхней секции и противовеса, после чего монтируют верхнюю секцию н- демонтируют кронштейн с противовесом .The invention relates to installation work, in particular, to methods of mounting by boom cranes of the tops of vertical hoist arms. Known methods of mounting jib cranes of the upper parts of vertical structures, such as the upper sections of chimneys, on pre-mounted lower sections. The aim of the invention is the possibility of using when installing jib cranes with insufficient hook lifting height. The goal is achieved by fixing the bracket to the upper section of the chimney at a level below its center of gravity, installing a counterweight at the free end of the bracket, lifting the crane by the bracket at the equilibrium point of the upper section and the counterweight, then mounting the upper section and dismantling the bracket with counterweight. The drawing shows the implementation of the proposed method of mounting the upper section of the chimney. To the upper section / chimney 2, bracket 3 is fixed below its center of gravity. Bracket 3 is attached to the free end of bracket 3. Hook 5 of crane 6 is fixed to the bracket 3 at the calculated equilibrium point of the counterweight 4 and the upper section / chimney 2 and mounting the upper section / on the pre-mounted sections of pipe 2. After installing the upper section / bracket 3 with the counterweight; 4 is dismounted. The subject of the invention. The method of mounting by jib cranes of the upper parts of vertical structures, nV Example of upper chimney sections, on the pre-; Radially mounted lower sections, characterized in that, in order to use when installing jib cranes with insufficient hook lifting height, a bracket is attached to the upper section of the chimney at a level below its center of gravity, a counterweight is attached to the free end of the bracket the crane behind the crown-, sh. tank at the equilibrium point of the upper section and the counterweight, after which the upper section is mounted; the bracket with the counterweight is dismantled.
