Embodiment Construction
[0018] A combination of herringbone-supported single-piece steel frames, steel beams and steel columns to strengthen the masonry structure and its construction method, see Figures 1 to 4 As shown, it includes the original wall body 11, herringbone supporting single-piece steel frame 1, connector 4, steel beam 2, steel column 3, column foot; said herringbone supporting single-piece steel frame 1 structural system consists of square steel column 5, square A single-piece two-dimensional steel frame system composed of steel beams 6 and diagonal supports 7; the width of the single-piece steel frame 1 of the herringbone support is the same as the width of the original gable wall 11 of a masonry structure house, and the height is the same as that of a multi-layer masonry structure house height; the square steel column 5 of the herringbone supporting monolithic steel frame 1 is provided with a reinforced concrete strip foundation, and bolts are embedded in the reinforced concrete stri...

The invention provides a masonry structure reinforced by adopting and combining a herringbone support single-piece steel frame, steel beams and steel columns and a construction method thereof. The masonry structure comprises an original wall body, the herringbone support single-piece steel frame, connection pieces, the steel beams, the steel columns and column feet; a herringbone support single-piece steel frame structure system is a single-piece two-dimensional steel frame system composed of square steel columns, square steel beams and sway braces; the width of the herringbone support single-piece steel frame is equal to that of the original wall body of a house gable wall of the masonry structure, and the height of the herringbone support single-piece steel frame is equal to that of a multi-layer masonry structure house; and the lower portions of the square steel columns of the herringbone support single-piece steel frame are provided with a reinforced concrete strip foundation, bolts are embedded in the reinforced concrete strip foundation, and the reinforced concrete strip foundation is connected and fixed with the column feet of the herringbone support single-piece steel framethrough bolts. Through the masonry structure, during an earthquake, wall cracking and wall collapsing can be effectively restrained, the structural integrity is improved, and damage of earthquake force to the wall body is reduced.
Description
technical field [0001] The invention relates to a masonry structure reinforced by a combination of herringbone-supported single-piece steel frames, steel beams and steel columns and a construction method thereof, which belongs to the technical field of seismic reinforcement of tough buildings. Background technique [0002] In recent years, old buildings with multi-storey masonry structures generally have low brick and mortar strength, which cannot meet the seismic requirements. Most of the floor and roof panels are reinforced concrete prestressed circular hole panels, and the length of the support at the end of the panel does not meet the requirements. Comprehensive reconstruction of seismic reinforcement. Although conventional reinforcement methods are more effective, residents are generally unwilling to reduce the usable area due to reinforcement, or to relocate due to reinforcement projects. At present, conventional reinforcement methods, such as board wall reinforcement...
