The invention discloses a detachable prefabricated assembly type steel-concrete composite structure and a construction method. The detachable prefabricated assembly type steel-concrete composite structure comprises prefabricated concrete plates, steel beams, high-strength bolts, embedded nuts and mounting nuts, and the prefabricated concrete plates are arranged at the position of an upper flange of the steel beam; the prefabricated concrete plates and the steel beams are connected through the high-strength bolts, the embedded nuts and the mounting nuts, preformed holes are formed in the prefabricated concrete plates, slotted holes are formed in the edges of the prefabricated concrete plates in a span mode, and standard holes are formed in the upper flanges of the steel beams. The high-strength bolts sequentially penetrate through preformed holes of the prefabricated concrete plates, the embedded nuts, the standard holes of the steel beams and the mounting nuts, the two adjacent prefabricated concrete plates in the span direction are connected with the extension steel bars of the prefabricated concrete plates at the slotted holes through threaded sleeves, and the structure has the advantages of being easy to construct and convenient to maintain; and the method has the advantages of being convenient to construct and good in economic benefit and environmental benefit.
Description
technical field [0001] The invention relates to a detachable prefabricated steel-concrete composite structure, which belongs to the technical field of structural engineering. Background technique [0002] The steel-concrete composite structure can give full play to the respective advantages of steel and concrete. Compared with the traditional concrete structure and steel structure, it has higher technical advantages and economic benefits. At present, the construction method of steel-concrete composite structure is still mainly in the form of cast-in-place, the construction is complicated, time-consuming and labor-intensive, and it is difficult to disassemble the structure after reaching the life cycle, especially the generated construction waste is very easy to cause environmental pollution. With the advancement of infrastructure and the introduction of the concept of green buildings, my country is actively exploring the innovation and development of composite structures, an...
