Sleeve combined type embedded part for rebar dense part of high-temperature gas-cooled reactor containment building

Abstract

The invention relates to a sleeve combined type embedded part for a rebar dense part of a high-temperature gas-cooled reactor containment building, and belongs to the technical field of nuclear powerengineering construction. The sleeve combined type embedded part comprises an anchor plate, a twistable anchor rib and a threaded connection sleeve. An internal thread is machined in the threaded connection sleeve. One end of the threaded connection sleeve is directly connected to the inner surface of the anchor plate through welding. An external thread is machined in one end of the twistable anchor rib. The end, with the external thread, of the twistable anchor rib is screwed into the internal thread of one end of the threaded connection sleeve and screwed down to form threaded connection. Bymeans of the sleeve combined type embedded part, the problem that conventional anchor plate-anchor rib welded type embedded parts especially some large embedded parts of a rebar dense part of a containment building are difficult to install in place is successfully solved, the installation quality and construction efficiency of the embedded part are greatly improved, the construction cycle of thecontainment building is shortened, and the sleeve combined type embedded part has application and popularization value for designing and installing of embedded parts of rebar dense parts in other nuclear reactor types and other engineering fields.

Description

technical field [0001] The invention relates to a sleeve-combined pre-embedded part for a high-temperature gas-cooled reactor containment where steel bars are densely packed, and belongs to the technical field of nuclear power engineering construction. Background technique [0002] The high-temperature gas-cooled reactor nuclear power plant is an advanced reactor type with independent intellectual property rights in my country and has the characteristics of the fourth-generation nuclear power. Its containment is composed of two compartments: a cylindrical reactor compartment and a rectangular steam generator compartment. It is an important safety barrier for the reactor system. . The vertical and horizontal reinforced steel bars in the containment wall are large in size and densely distributed. Especially in a large number of wall concealed column areas and penetration parts, the steel bars have complex shapes and denser arrangements. Embedded parts and steel cladding for we...
