Abstract

The invention relates to an external ring beam constructional column expansion joint structure and a construction method thereof. The external ring beam constructional column expansion joint structure comprises an external ring beam, external constructional columns and L-shaped anchor bars, wherein the external constructional columns are arranged on the two sides of an expansion joint, the external constructional columns on each side and the external ring beam are integrally poured to form a closed whole along the periphery of the building, the external constructional columns are connected with the original structure wall body through the L-shaped anchor bars, the anchor slurry of the L-shaped anchor bars in the anchor holes of the wall body is grouted by adopting A-grade structural adhesive, and the L-shaped anchor bars, constructional column main bars and constructional column stirrups are bound and poured together.

Description

technical field [0001] The invention relates to an expansion joint structural structure of an external ring-beam structural column and a construction method thereof, and belongs to the technical field of comprehensive transformation of existing buildings. Background technique [0002] At present, masonry structure houses are the main structural form in existing buildings in our country, accounting for more than 60% of civil buildings. However, due to the basic materials and connection methods of the masonry structure, the structural brittleness, small deformation capacity, and poor seismic performance have caused serious earthquake damage in previous earthquakes. Therefore, the research on the seismic reinforcement of masonry structures is an important problem to be solved in today's structural engineering. The most commonly used reinforcement method for masonry structures is the seismic reinforcement method using reinforced concrete ring beams, structural columns, and inte...
