Abstract

The invention relates to an anchoring joint of a newly added frame rebar and an original structure and a construction method of the anchoring joint. The joint comprises original concrete structures on the two sides, connecting holes formed in the original concrete structures, the newly added frame rebar, straight thread connection sleeves and backing plates, wherein the newly added frame rebar at least comprises an upper layer main rebar and a lower layer main rebar, the connecting holes penetrate through the original concrete structure on one side or the original concrete structures on the two sides, moreover, the connecting holes on the two sides are in the same straight line, threads are arranged at the end on one side or the ends on the two sides of the newly added frame rebar, the threaded ends penetrate through the connecting holes from inside to outside, the backing plates and the straight thread connection sleeves are used for being anchored on the outer sides of the original concrete structures, and the inner diameter of the straight thread connection sleeves fits the outer diameter of the threaded ends. The problem of anchoring the newly added rebar when the depth of an embedded rebar is insufficient or construction space is small is solved, and the technical problem of earthquake-resistant requirements in joint core areas is solved.

Description

technical field [0001] The invention relates to a connection node of a building component and a construction method thereof, in particular to a node for anchoring the newly added frame reinforcement and the original structure. Background technique [0002] At the construction site, certain structural components are often added due to design changes and on-site construction needs. The steel bars of these newly added structural components need to be reliably connected to the original structure. The traditional method generally adopts the rebar planting process, that is, to drill steel bar holes in the original structure, inject the bar planting glue into the steel bar holes, and then implant the steel bars of the new structure, so that the new steel bars can be reliably connected with the original structure. The process method is currently widely used in construction engineering. [0003] The use of planting glue to deal with the joints of the old and new structures is more c...
