Embodiment Construction
[0025] Such as Figure 1-5 Shown, a kind of prefabricated multilayer brick-concrete structure reinforcement method of the present invention, its specific implementation is as follows:
[0026] Including the original multi-storey brick-concrete structure, it also includes square steel concrete structural columns 1, channel steel ring beams 11 and flat steel tie rods. At the intersection of the walls, the lower part of the square steel concrete structural column 1 is provided with a structural column foundation. The structural column foundation includes the lower concrete base 5 and the upper cast-in-place concrete column pier 3. The concrete base 5 is connected with the original foundation 10 of the original multi-storey brick-concrete structure through the 4 bolt connections of the bottom plate of the structural column; The channel steel ring beams 11 are connected together by bolts of an additional partition support beam 12; prestressed flat steel tie rods are arranged on th...

The invention relates to a method for reinforcing an assembly type multilayer brick-concrete structure, and belongs to the technical field of seismic strengthening. The assembly type multilayer brick-concrete structure comprises an original multilayer brick-concrete structure and further comprises a square steel concrete constructional column, a steel channel ring beam and a flat steel drawing rod. The square steel concrete constructional column is arranged outside the original multilayer brick-concrete structure, the outer side of the longitudinal wall, the outer side of the gable wall and the crossed intersection point of the longitudinal wall and the transverse wall, and a constructional column foundation is arranged on the lower portion of the square steel concrete constructional column. The steel channel ring beam is arranged on the square steel concrete constructional column along the floor height, and the square steel concrete constructional column and the steel channel ring beam are connected together through an external-added clapboard supporting beam bolt. The prestress flat steel drawing rod is arranged on the transverse wall inside the original multilayer brick-concrete structure. The method effectively overcomes the defects in the original reinforcing method, improves the construction speed, increases structural safety, and has significance for further researching and implementing seismic strengthening of the existing house of the brick-concrete structure, comprehensively reconstructing the old house and perfecting and improving a seismic strengthening method.
Description
technical field [0001] The invention relates to a method for reinforcing an assembled multi-layer brick-concrete structure, which belongs to the technical field of seismic reinforcement. Background technique [0002] Multi-storey brick-concrete structure houses are the main structural form in existing buildings in my country, accounting for more than 60% of civil buildings. However, due to the brittle nature of the basic materials and connection methods of the brick-concrete structure, the deformation capacity is small and the seismic performance is poor, and the earthquake damage has been serious in previous earthquakes. Therefore, research on the theory and technology of aseismic reinforcement of masonry-concrete structures is an important subject of current structural engineering research. In particular, the country is currently carrying out earthquake-resistant appraisal and comprehensive renovation of safety and energy saving for old houses. It is urgent to study the ...
