Abstract
The invention relates to masonry structure toughness improvement by adopting a combination of vertical drilling embedded steel bars and a roof steel base plate in a wall body and a construction methodof the masonry structure toughness improvement, and belongs to the technical field of tough building earthquake resistance. The structure involves an original outer wall body, threaded steel bars andthe roof steel base plate, wherein a hole is drilled in the position, corresponding to the interior of the original outer wall body, of the upper portion of a roof, the drilling position is the center of the interior of the original outer wall body, the hole extends to the roof and penetrates through the outer wall body and a floor to reach a foundation of the masonry structure, the threaded steel bars are implanted, polymer mortar is poured into the hole, and one end of the roof with the threaded steel bars is connected with the roof steel base plate through nuts in a fastened mode. According to the masonry structure toughness improvement by adopting the combination of the vertical drilling embedded steel bars and the roof steel base plate in the wall body and the construction method ofthe masonry structure toughness improvement, the toughness of masonry can be effectively enhanced, wall body crack developing can be restrained during an earthquake, the integrity of the wall is enhanced, and damage of earthquake force to the upper part of the structure is reduced.
Description
technical field [0001] The invention relates to a method for improving the toughness of a masonry structure by adopting a combination of vertically drilled and planted reinforcement in a wall and a roof steel backing plate, and a construction method thereof, belonging to the technical field of earthquake resistance of tough buildings. Background technique [0002] At present, a large number of masonry structures in my country have no ring beam structural columns, which seriously affect the toughness required for the masonry walls to resist earthquakes. The simple external ring beam structural columns have the following problems: wet operation on site, difficult construction, difficult concrete feeding, Formwork support is difficult, and the output rate of effective reinforcement construction is low. The combination of vertically drilled reinforcement and roof steel plate in the wall can greatly improve the overall earthquake resistance and toughness of the masonry structure. ...
