Description

Technical Field

[0001] The invention relates to the technical field of steel structure factory buildings, in particular to a steel structure factory building frame. Background Art

[0002] A nuclear power plant mainly consists of two parts: the nuclear island and the conventional island. Conventional island buildings such as turbine rooms, pump rooms, warehouses, office buildings and living quarters are mostly made of steel structures. Steel structure plants mainly refer to buildings whose main load-bearing components are made of steel, including steel columns, steel beams, steel structure foundations, steel roof trusses, steel roofs, and steel structure walls can also be maintained with brick walls. The roof of a nuclear power plant is usually equipped with adjustable glass skylights to achieve the purpose of ventilation and lighting.

[0003] For example, the Chinese patent with publication number CN112727171A and titled "A Steel Structure Factory Frame" includes a first column, a transverse beam, a first connecting seat, a shock-absorbing fixed seat, a second column, an oblique beam, a purlin, an adjustable fixed seat, a skylight, a first longitudinal beam, a second longitudinal beam, and an adjustable mechanism; the first connecting seat is fixed to the top of the first column, and the shock-absorbing fixed seat is fixed to the bottom of the first column; both ends of the transverse beam are fixedly connected to the first column; one end of the second column is fixedly connected to the transverse beam; both ends of the second longitudinal beam are connected to the first connecting seat; both ends of the oblique beam are movably connected to the first connecting seat and the second column respectively; the adjustable fixed seat is fixed to the oblique beam; the purlin is fixedly connected to the adjustable fixed seat; both ends of the first longitudinal beam are fixedly connected to the top of the second column; and the adjustable mechanism is fixed to the transverse beam.

When the glass skylight 38 is reset, the cleaning plate 5 can improve the lighting efficiency. If you want to achieve sunshade while dissipating heat and smoke to prevent sunlight from entering the factory and heating up the factory, you can drive the connecting bracket 34 away from the cylinder The cleaning plate 5 moves in the direction of the sun, and the protective cover 4 rotates toward the sun to block the sunlight, thereby preventing the sunlight from entering the factory building.
