Earthquake-resistant reinforcement assembly

摘要

An earthquake-resistant reinforcement assembly according to one embodiment of the present invention comprises: a rod of which one end is hinge-coupled to an upper structure; a combination pin which is formed at the other end of the rod and is extended to diametrically cross the rod; and a bracket which is provided on a partition wall of a nuclear reactor containment building and is coupled with the other end, wherein the bracket can withstand a tensile load and a torsional load by including first and second members which face each other and are extended in parallel to load the rod thereon, and groove portions which are formed at the first and second members to be coupled with the combination pin to form the shape of a double bracket.

1. An earthquake-resistant reinforcement assembly formed to support the longitudinal and transverse directional behavior of a nuclear reactor upper structure when an earthquake occurs, comprising:
a rod an end of which is hinge-coupled to the upper structure; a coupling pin formed at the other end of the rod, and extended to diametrically cross the rod; and a bracket installed at a partition wall of a nuclear reactor containment building, and coupled to the other end thereof, wherein the bracket comprises:
a first and a second member extended in parallel to face each other so as to allow the rod to be placed therewithin; andgroove portions formed on the first and the second member, respectively, to be coupled to the coupling pin, wherein lateral surfaces constituting each of the groove portions are formed to be inclined at a predetermined angle toward the upper structure from a vertical surface thereof, wherein inclinations of at least one of the lateral surfaces for each of the groove portions begin at openings of the groove portions, and wherein the groove portions are formed so that cross-sectional areas of the groove portions increase as the groove portions extend away from the openings so as to increase an area in contact with the coupling pin in an axial direction of the coupling pin.
