Description

Technical Field

[0001] The utility model belongs to an industrial building structure, in particular to a load-bearing structure for a power distribution room. Background Art

[0002] During the project design process, a power distribution room is often essential. However, the equipment in the power distribution room, especially the transformer, is extremely heavy, so the power distribution room on the floor requires a special load-bearing structure to meet the load-bearing requirements.

[0003] like Figure 1 As shown, an existing load-bearing structure of a distribution room includes a main beam 1, a concrete slab 2 is cast on the main beam 1, three secondary beams 21 are set at the bottom of the concrete slab 2, the secondary beams 21 are embedded in the main beam 1, and three load-bearing masonry walls 4 are installed on the top surface of the concrete slab 2 at the position of the secondary beam 21, namely, a first load-bearing masonry wall 41, a second load-bearing masonry wall 42, and a third load-bearing masonry wall 43.

A top ring beam 52, a third top ring beam 53, a cover plate 6 is installed between the top surfaces of the first top ring beam 51 and the second top ring beam 52, the first load-bearing masonry wall 41, the second load-bearing masonry wall 42, the first top ring beam 51, the second top ring beam 52, the concrete slab 2 and the cover plate 6 constitute a cable trench 9; a filling cushion layer 7 is cast on one side of the third load-bearing masonry wall, a concrete layer 8 is cast on the filling cushion layer, a transformer 11 is placed on the concrete layer 8, and a distribution cabinet 10 is placed between the top surfaces of the first top ring beam 51 and the second top ring beam 52.

[0004] Although this structure ensures the beauty of the interior space, in order to ensure that the structural strength of the building is sufficient to support the extremely heavy transformer, a thicker filling pad needs to be laid. The laying of the filling pad will cause the floor load to increase. In addition, the transformer itself is heavy, which leads to excessive building load and extremely high cost. Utility Model Content
