Description

Technical Field

[0001] The utility model relates to a method of reinforcing a wooden column by using an externally wrapped lattice steel member, and belongs to the technical field of comprehensive reconstruction of old houses. Background Art

[0002] At present, there are still many old masonry houses with wooden columns, which will be damaged to varying degrees due to their age. For example, if the bottom of the wooden column is rotten, cracked by force or eaten by insects, etc., the wooden column with serious damage should be replaced by new wooden columns, brick columns or reinforced concrete columns when it is renovated. When the quality of the wooden column is good, there is no serious damage such as rot, cracked by force or eaten by insects at the bottom, and the bearing requirements are met, the wooden column should be reinforced by steel wrapping, external brick columns (additional wall), new reinforced concrete frames, and new steel frames in combination with the front longitudinal wall. The utility model uses external lattice steel components to carry out seismic reinforcement for the wooden columns of the masonry structure, which can improve the overall seismic resistance of the original structure, so that the new and old structures can jointly bear the earthquake effect, thereby enhancing the toughness of the house and preventing the collapse of the structure. The use of external lattice steel components to reinforce wooden columns is simple in construction, reasonable in structural force, and has good economic and environmental benefits.
