Description

Technical Field

[0001] The invention relates to the field of theatre sill installation, in particular to a block-assembly hoisting method for a stage sill in a complex venue. Background Art

[0002] The stage grid roof is commonly known as the grape rack. It is located at the top of the stage tower. It is not only the basic space for the stage machinery and HVAC equipment on the stage, but also the hollow working layer of the stage. The grid roof of the early theater was a wooden structure, which has now been replaced by a steel structure. The steel structure of the grid roof is not only closely related to the stage machinery, but also closely related to the architectural structure of the theater. It is a transition layer connecting the stage machinery and equipment and the theater structure, and is an indispensable part. The ridge top is the carrier of the stage machinery. The use of stage machinery such as lifting railings, lifting orchestra pit lighting cages, lighting hanging pieces, electric boom lifts, and winches is realized on the ridge top. Therefore, the precise installation of the ridge top ensures the normal use of various stage machinery, the smooth realization of stage performances, and the safety of venue personnel.

[0003] There are many problems with the installation of traditional sills. 1. The sills are composed of a large number of steel structure components. The use of a single bulk method increases the number of hoisting times and time, affecting the construction progress; operators need to use climbing equipment or set up operating scaffolding for installation, and there are many installation nodes, special materials, and welding and installation are all carried out at high altitude, affecting safety. 2. If the sill is hoisted as a whole, the required hoisting equipment has a large lifting capacity. There is no large crane available in the closed environment of the upper roof, and the selection of hoisting equipment is a difficult problem. In addition, the overall plane area of ​​the sill is large, covering the stands and stage areas. The steel beam components are numerous and short. It is difficult to be accurate after the overall family is assembled, and it is difficult to ensure that the deviation is within the allowable range; 3. Welding, bolt connection, anti-corrosion coating, fire retardant coating, etc. are all operated at high altitude, which seriously affects the safety below, and there is a risk of falling objects, and the safety risk of cross-construction is seriously increased.
