However, if hoisting by hoisting machinery is used in a limited space, because multiple temporary supports need to be erected, if hoisting within the span is selected, the temporary supports will block the travel route of the hoisting equipment. To shield the hoisting machinery, extremely large hoisting equipment is required, and the hoisting is difficult, and the largest hoisting equipment available on the market cannot meet the performance requirements of some component hoisting
If the overall hoisting method of ectopic assembly is adopted, it cannot be realized due to the shelter of the reserved building

The invention provides a mounting method of a steel roof. The mounting method is used for installing the steel roof on a support main body below an original roof of a building body; the building bodyfurther comprises a reinforced concrete column for supporting the original roof, and the support main body is positioned in an internal space formed by the reinforced concrete column and the originalroof; the mounting method comprises the steps that a lifting frame is installed on the support main body; hoisting equipment lifts materials required by the steel roof to a temporary support frame ina chamber of the support main body to assemble the steel roof; the lifting frame lifts the steel roof to the bottom of the original roof and is installed on the support main body below the original roof; and an embedding section is arranged between the steel roof and the support main body. Before lifting, splicing construction is conducted on the temporary supporting frame of the internal space defined by the support main body, and blocking of a building body to movement of the steel roof does not need to be considered; and after assembly is completed, the lifting frame installed on the support main body is used for being lifted to the bottom of the original roof, and the limitation of limited space on lifting does not need to be considered.
Description
Technical field[0001]The invention relates to the field of construction, in particular to a method for installing a steel roof.Background technique[0002]With the increasing demand for urban renewal, more meaningful buildings have been retained and reconstructed. In order to meet the needs of new functions, the large-span steel roofs in the buildings are retained to achieve large-space and multi-functional designs. It is extremely difficult.[0003]For the installation of large-span steel structures, hoisting machinery can generally be used, temporary supports can be erected in sections, or the overall hoisting can be assembled in different positions. However, if the hoisting method of hoisting machinery is used in a limited space, because multiple temporary supports need to be erected, and hoisting within the span is selected, the temporary support will block the hoisting route of the lifting equipment. If hoisting outside the span is selected, the building body will be retained. To s...
