Description

Technical Field

[0001] The invention relates to the field of building decoration, and in particular to a super-high integrated column construction method and a column. Background Art

[0002] In some large exhibition halls, concert halls and other places, due to the large internal area and high internal height of the buildings, the single-story height of some buildings can reach more than 20 meters. Columns are usually installed as structural supports. In the later decoration process, the outside of the columns will also be decorated. Common ones include painting the outside of the columns and installing decorative panels.

[0003] Common decorative panels such as stone, aluminum panels, and composite decorative panels require a lot of work to install due to the high height of the columns. Although the installation workload is reduced by using relatively large decorative panels, the weight of a single decorative panel increases, making it more difficult to position and install at high altitudes.

[0004] When using relatively large-area decorative panels for installation, it is also necessary to use lifting equipment and climbing equipment for assistance. Common lifting equipment includes cranes, and climbing equipment includes articulated boom aerial work platforms. During the installation process, the decorative panel is lifted by the crane to the installation position. The construction personnel use the climbing equipment to adjust the position of the decorative panel to the installation position and fix it. Since the area of ​​a single decorative panel is relatively large and the weight is relatively heavy, the size of some decorative panels can reach 2420×3740mm and the weight can reach 700kg, which makes it difficult to adjust the positioning and install and fix.

[0005] In addition, the existing columns usually have a single function and only have a supporting role, which cannot meet the existing functional requirements. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides an ultra-high integrated column construction method and column, which integrates fire-fighting pipelines, ventilation fan pipelines and fire alarm wires into the column, fully utilizing the height space of the column. There is no need to set up additional steel frames and other structures for the layout of fire-fighting pipelines and ventilation fan pipelines, and also solves the problem of difficulty in installation and positioning of large-area decorative panels.

[0007] The technical objectives of the present invention are achieved through the following technical solutions:
