Description
Technical Field
[0001] The utility model relates to a plant column structure for an aluminum electrolysis workshop, belonging to the technical field of plant structures for aluminum electrolysis workshops. Background Art
[0002] The aluminum electrolysis workshop covers a large area, usually with a span of 30m, a length of 1300m, and a height of about 20m. In addition to the electrolytic cell in the workshop, there is also an operating table next to the electrolytic cell for operations such as running the bag lift truck. The operating table is subject to large forces and requires heat insulation. The design requires a reinforced concrete structure, with a rigid frame (steel beam and steel column) above the operating table, and the embedded end of the steel column (below the operating table) is a reinforced concrete column. In the prior art, the construction sequence is to first construct the operating table and the reinforced concrete structure below (including the tank foundation), and then construct the rigid frame (steel beam and steel column) above the operating table. Since the reinforced concrete column has to bear both the load transmitted from the operating platform and the internal force (axial force, bending moment, shear force) transmitted from the steel column, the cross-section of the reinforced concrete column is large, so the construction period is long, the construction difficulty is high, and the cost is high. Utility Model Content
[0003] In order to overcome the problems of the prior art, the utility model provides a plant column structure for an aluminum electrolysis workshop. While meeting the requirements of the high temperature resistance and heavy load bearing of the operating table, the cross-section of the reinforced concrete column below the operating table is reduced and the number of anchor bolts is reduced, thereby saving construction costs, changing the construction process and shortening the construction period.
[0004] The technical solution of the utility model is: a plant column structure for an aluminum electrolysis workshop, comprising a plant, a plant foundation is arranged on the side of the plant, an electrolytic cell foundation is arranged in the plant, a steel-concrete column is arranged on the plant foundation, a reinforced concrete column is arranged next to the electrolytic cell foundation, and an operating platform is arranged on the steel-concrete column and the reinforced concrete column.
[0005] The steel-concrete column comprises an inner steel section, bolts are arranged on the side of the steel section, reinforced concrete is arranged outside the steel section, an operating platform is hinged on the top surface of the steel-concrete column, and the operating platform and the reinforced concrete column are cast as a whole.
[0006] Refractory bricks are arranged on the cantilever of the operating platform.
[0007] The upwardly extending part of the steel-concrete column is a steel column, and the steel column and the crossbeam form a portal frame.
[0008] The roof is installed on the portal frame.
[0009] The thickness of the reinforced concrete of the steel-concrete column is 250-400 mm.
[0010] The construction method of the column structure of the aluminum electrolysis workshop is to construct the foundation of the workshop first, and then install the steel in the steel-concrete column on the foundation of the workshop. The extension part on the steel is the steel column. The crossbeam is constructed on the steel column to form a portal frame, and the roof is installed on the portal frame. After the roof construction is completed, the electrolytic cell foundation, steel-concrete column, reinforced concrete column and operating platform are constructed in the workshop.
[0011] The electrolytic cell foundation, steel-concrete columns, reinforced concrete columns and operating platform are constructed in the factory building. Specifically, steel bars are bundled outside the steel and concrete is poured to obtain the steel-concrete columns as hinged supports on one side of the operating platform. The operating platform and the reinforced concrete columns on the other side are integrally cast and formed. Refractory bricks are installed on the cantilever of the operating platform. At the same time, the electrolytic cell foundation is constructed, and then the electrolytic cell is installed on the electrolytic cell foundation.
[0012] Due to the adoption of the above technical scheme, compared with the prior art, the utility model adopts steel-concrete piles as factory columns, reduces the cross-section of reinforced concrete columns, saves concrete usage, reduces the number of anchor bolts, saves construction costs, and is convenient for construction. At the same time, the construction process can be changed. After the steel-concrete factory columns are installed, the portal frame can be constructed first, and after the roof is completed, the reinforced concrete structure and trough foundation below the operating table can be constructed, which shortens the construction period. After the roof is completed, it is more convenient to construct the reinforced concrete structure and trough foundation below the operating table in rainy and snowy weather, and the space that has not been constructed yet can also be used for material stacking. The utility model can meet the bearing capacity requirements and use requirements, is convenient for construction, and at the same time, by changing the construction process, it can make full use of the site and facilitate the construction of the trough foundation and reinforced concrete structure in rainy and snowy weather.
