High-altitude rotation construction method for large-scale venue steel awning

Abstract

The invention discloses a high-altitude rotation construction method for a large-scale venue steel awning, and relates to the technical field of constructional engineering. The method comprises the following steps: the steel awning is divided into a roof awning and a facade awning, and the roof awning is divided into n rotating structure units; after construction of a venue concrete main body structure is completed, the facade awning starts to be constructed, meanwhile, a horizontally-assembled supporting jig frame is installed on a stand structure, a lifting frame is installed in a venue, and three transverse linkage beams are arranged at different elevation positions of the front lifting frame; after the horizontally-assembled supporting jig frame is installed, the facade awning and the rotating structure units are assembled, and limiting devices are arranged; and lifting equipment is installed on the lifting frame, the lifting equipment and a cross-core oil cylinder are connected through a buckle cable, the rotating structure units continue to be rotationally lifted to the designed elevation, rotating hinges are packaged and welded, and then rod pieces between the rotating structure units are installed in an inlaying mode. By means of the method, the high-altitude work amount is remarkably reduced, the construction efficiency and the construction safety coefficient are improved, and the construction quality is also guaranteed.

Description

Technical field [0001] The present invention relates to the field of construction engineering, and in particular to high empty rotational construction methods of large venue steel masks. Background technique [0002] In recent years, with the further development of large-scale public cultural venues in my country, the steel masks have emerged, the structure type is complex, the shape is novel, the components is large, the weight is heavy, the structural span is large, and the installation is high. At present, the common construction methods for installation of steel masks of large venues include high-altitude bulk, tie or block mounting method, high-altitude slip method, overall lifting method, overall lifting method, overall top rising method. [0003] The high-altitude scattered method refers to the method of collecting small units or disc (single rods, and single nodes) in design position, suitable for various types of grids of bolt connection nodes, especially those suitable ...

Problems solved by technology

[0006] For the steel canopy of large-scale venues with large component size, heavy weight of rods, large structural span and super high installation height, especially the steel canopy with super long cantilever giant ribbed space folded plate grid structure, the existing steel canopy is used The canopy installation method has been difficult to meet the installation requirements of such steel structure projects, so it is necessary to provide a high-altitude rotary construction method for large-scale venue steel canopies
