Description

Technical Field

[0001] This utility model belongs to the technical field of hydropower plant buildings, specifically relating to the superstructure of a hydropower plant's ground-level powerhouse. Background Technology

[0002] A hydroelectric power plant is a complex of hydraulic structures, machinery, and electrical equipment, and also serves as the workplace for operating personnel. Therefore, the safety and durability of the power plant are of paramount importance.

[0003] The superstructure of the ground powerhouse is the part above the generator floor, mainly including frame columns, crane beams, and the roof. In commonly used hydroelectric powerhouse superstructures, the walls are mostly of a "frame column + connecting beam + brick masonry" structure, and the roof bottom structural beams are mostly cast-in-place concrete structures. This type of powerhouse superstructure has relatively low investment and mature construction technology, but the overall structural integrity is poor, the construction procedures are complicated, and the construction period is long. Utility Model Content

[0004] The purpose of this utility model is to provide a superstructure for the surface powerhouse of a hydropower station, which solves the problems of poor overall integrity, complicated construction procedures, and long construction period of existing surface powerhouse superstructures.

[0005] The technical solution adopted by this utility model is that the upper structure of the ground powerhouse of the hydropower station includes a frame structure, a precast goose-shaped roof fixed to the top of the frame structure, crane beams fixed between the frame structures, and a protective wall fixed to the outer side of the top of the frame structure.

[0006] The features of this utility model also include:

[0007] The frame structure includes two rows of frame columns along the axis of the factory building, with equal spacing between each row of frame columns. The frame structure also includes two rows of wind-resistant columns along the span of the factory building, with equal spacing between each row of wind-resistant columns.

[0008] Shear walls are fixed between adjacent frame columns and between adjacent wind-resistant columns, and all frame columns, wind-resistant columns and shear walls form a rectangular frame structure.

[0009] The frame structure also includes several precast trough beams. The bottom ends of each precast trough beam are fixed to the tops of two adjacent frame columns, and the top of the precast trough beams on the side away from the shear wall is fixed to a precast goose-shaped roof.

[0010] The frame column includes an upper column at the top of the frame column and a lower column at the bottom of the frame column. The size of the upper column is smaller than that of the lower column. The bottom ends of the precast channel beam are fixedly connected to the top of the adjacent upper column.

[0011] Protective walls are fixed to the top of the precast trough beams near the shear wall, the top of the wind-resistant columns near the shear wall, and the top of the shear wall connected to the wind-resistant columns. The protective walls are rectangular frame structures. Protective walls are fixed to the top of the precast trough beams and the wind-resistant columns near the shear wall.

[0012] The spaces between adjacent precast trough beams are filled with cast-in-place concrete.

[0013] A crane beam is fixed to the top of the lower column, away from the shear wall.

[0014] The precast goose-shaped roof is a precast reinforced concrete structure, the crane beam is a precast concrete or steel structure, and the protective wall is a cast-in-place concrete structure.

[0015] The beneficial effects of this utility model are:

[0016] The superstructure of the hydropower station's surface powerhouse provided by this utility model, compared with the traditional surface powerhouse superstructure, adopts a wall structure of "frame columns + continuous shear walls." This improves the rigidity of the superstructure and allows for the use of sliding formwork construction, resulting in a high degree of mechanization. It enables flexible formwork adjustment, saving on materials and labor required for formwork and scaffolding erection, simplifying construction procedures, and improving construction efficiency. Compared with traditional cast-in-place concrete beams, the precast channel beams at the bottom of the roof eliminate the need for formwork support, saving on project investment, accelerating construction progress, and shortening the construction period.
