Abstract

The invention relates to a modular steel containment vessel annular hanging beam and an assembling method thereof. The annular hanging beam has a simple structure, and is convenient to use; and high-altitude assembling and welding operation is avoided and the safety risk of the operating process is lowered greatly. The annular hanging beam comprises a plurality of containment vessel arc plates which are spliced to form an entire ring; the inner wall of each containment vessel arc plate is provided with a plurality of annular hanging beam modules so as to constitute a split annular hanging beam; each annular hanging beam module comprises an upper annular plate and a lower annular plate; and a rib plate and a vertical plate are connected between the upper annular plate and the lower annularplate.

Description

technical field [0001] The patent of the present invention relates to a load-bearing component and its installation and assembly method, and is especially suitable for a modular steel containment ring suspension beam and its assembly method. Background technique [0002] At present, in nuclear power plants, the steel containment vessel and its ring suspension beam are the key components in the nuclear island, which are pressure-bearing parts and load-bearing parts closely related to nuclear safety. In the Chinese invention patent 201010187940.8, an installation scheme of corbel-type containment ring suspension beams is provided. This corbel-type structure is complex and is installed on a steel lining with a thickness of about 6mm, and the steel lining cannot independently undertake ring suspension. The ring hanging load transmitted by the beam also needs to connect the corbel with the concrete wall through steel bars; at the same time, this corbel-type ring hanging beam is m...
