Description

Technical Field

[0001] This application relates to the field of building construction technology, and more specifically, to a quick-installation hollow column. Background Technology

[0002] Currently, existing buildings are divided into traditional buildings and prefabricated buildings. Traditional construction involves a large amount of on-site work, with most tasks requiring manual labor, resulting in low labor productivity, significant quality and safety issues, high energy consumption and emissions, and the generation of substantial construction waste. Therefore, prefabricated buildings are being vigorously promoted. Prefabricated buildings refer to buildings assembled on-site using prefabricated components produced in factories. The prefabricated construction model employs standardized design, factory production, and assembly-based construction, transferring a large amount of on-site work from traditional construction methods to factories. It is a new type of sustainable building production method that can achieve energy conservation, environmental protection, and maximize the life-cycle value of building products.

[0003] When manufacturing precast components, it is usually necessary to construct a corresponding hollow column to facilitate rapid casting to form the precast component. In existing technology, a reinforcing cage is formed by binding vertical and horizontal reinforcing bars or stirrups. A formwork is then erected around the reinforcing cage, and a structure for fixing the formwork according to the precast component's structure is installed to form the hollow column for casting. Concrete is then poured into the hollow column, and after the concrete has solidified and reached a certain strength, the formwork is removed to obtain the precast component. The entire hollow column structure is complex and requires subsequent dismantling, extending the construction period. Furthermore, different precast components require different formwork structures, which can easily lead to material waste and increase construction costs. Utility Model Content

[0024] The quick-installation cavity column provided in this application aims to solve at least one technical problem existing in the prior art.

[0025] This application provides a quick-installation hollow column, such as... Figures 1-5 As shown, the quick-assembly hollow column includes a first structure, a bottom shell, and a top shell. The first structure includes a reinforcing cage 1 and a first mold shell 2 and a second mold shell 3 of concrete structure. The first mold shell 2 and the second mold shell 3 are located on the first opposite sides of the first structure and are fixedly connected to different sides of the reinforcing cage 1. The first mold shell 2 and the second mold shell 3 are provided with a fixing member 9 on their opposite sides. The fixing member 9 is used to fix the first mold shell 2 and the second mold shell 3 to the opposite side of the reinforcing cage 1 to form the first structure. The bottom shell and the top shell are cast and formed on the second opposite side of the first structure and are fixedly connected to the reinforcing cage 1.

[0026] Optionally, the reinforcing cage 1 is a square column structure, with the first mold shell 2, the second mold shell 3, the top shell, and the bottom shell fixed to different sides of the square column structure. The first mold shell 2, the second mold shell 3, the top shell, and the bottom shell surround the reinforcing cage 1 and form a square column cavity for casting precast components. The sides of the first pair of opposite sides may be perpendicular to the sides of the second pair of opposite sides. The top shell and the bottom shell may be located on different sides of the first structure.

[0027] Optionally, the thickness of the first mold shell 2, the second mold shell 3, the top shell, and the bottom shell, as well as the type of concrete used, can be determined according to the strength, application environment, cost, and other requirements of the quick-assembly hollow column, and are not limited here.

This first structure is placed on the mold platform 4 corresponding to the bottom shell, with the side of the first structure used to set the bottom shell contacting the mold platform 4, and the bottom shell is poured.
