Combined tower crane for roof construction and construction method thereof

Abstract

The invention relates to a combined tower crane for roof construction and a construction method thereof and belongs to the technical field of architectural engineering. The combined tower crane for roof construction and the construction method thereof are used for solving the technical problem that a conventional tower crane and other mechanical equipment cannot be used for hoisting construction normally under the condition that the structure of a roof is complex. The combined tower crane comprises a first roof surface crane body and a second roof surface crane body which are arranged in parallel. The first roof surface crane body is installed on a roof through a supporting frame. The second roof surface crane body is connected with the roof through a tower crane foundation. The tower crane foundation comprises a tower body and foundation steel beams. The upper end of the tower body is in rotary connection with the second roof surface crane body. The lower end of the tower body is in fixed connection with the foundation steel beams. The foundation steel beams are fixedly connection with the roof. The construction method comprises the steps that 1, the first roof surface crane body is fixedly installed in the position, above a core barrel, of the roof through the supporting frame; 2, the foundation steel beams are fixedly installed on the roof, and the tower body is fixedly installed over the foundation steel beams; and 3, the second roof surface crane body is lifted through the first roof surface crane body, so that a lower rotation body at the bottom of the second roof surface crane body is in rotary connection with an upper rotation body of the tower body.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a combined tower crane for roof construction and a construction method thereof. Background technique [0002] With the continuous development of urban construction, old buildings or buildings that have been built for a long time need to be remodeled, especially the roofs of more and more high-rise buildings need to be remodeled. In the roof reconstruction of high-rise buildings, tower cranes are often used to hoist components. The more commonly used tower cranes are roof cranes, and roof cranes do not have a supporting tower body, so they have higher requirements for installation locations. During the roof renovation construction, when the roof structure is complex, especially when the elevation of the top surface of each part is large, the roof crane cannot meet the construction requirements for hoisting. Therefore, how to provide an easy-to-operate, low-cost, ...
