Problems solved by technology
[0004] In the construction of workshops, especially steel-reinforced concrete workshops in the metallurgical industry that work under large-scale, high-temperature, and heavy-load conditions, there are not only steel-reinforced concrete beams, but also steel-reinforced concrete columns, and the steel-reinforced concrete beams and steel-reinforced columns inside the concrete The form of the joint is particularly complicated; the installation accuracy of the steel skeleton composed of steel columns and steel beams is high, and the operation is difficult; Dense concrete reinforcement consisting of studs, stressed reinforcement and transverse fixed stirrups brings a lot of inconvenience to the arrangement of concrete reinforcement, especially at the joints, and cannot ensure the integrity of the concrete reinforcement outside the steel skeleton. layout quality, the overall quality of steel reinforced concrete is reduced after pouring
In addition, concrete reinforcement is added to the outside of the steel skeleton, and the pouring of concrete is also more difficult, and the construction is more difficult, and the pouring quality of steel reinforced concrete cannot be well guaranteed. Compared with steel structure and concrete structure, steel reinforced concrete frame structure for industrial workshop has many advantages mentioned above, but also because steel reinforced concrete has many technical problems mentioned above in structure and technology, it has not been widely used in existing construction projects. The popularization and application, especially in the construction of large-scale metallurgical industrial plants working under large-scale, high-temperature, and heavy-load conditions, has never been adopted

The invention discloses a mounting method of steel reinforced concrete steel skeleton of a large metallurgical industrial factory, belonging to the technical field of factory building construction production. The invention provides a mounting method of steel reinforced concrete steel skeleton of the large metallurgical industrial factory, which has little operation difficulty and can guarantee the mounting quality of steel reinforced concrete steel skeleton. The mounting method comprises the following steps: embedding foundation bolt on a steel reinforced column mounting base, and preparing abox-type steel reinforced column and an H-type steel reinforced beam; hoisting the steel reinforced column onto the steel reinforced column mounting base of the steel reinforced column mounting and adjusting device, and primarily fixing with foundation bolt and temporary fixing cable wind rope; adjusting the mounting quality of the steel reinforced column by use of the mounting and adjusting device and the cable wind rope; after the mounting quality is qualified, assembling the steel reinforced beam between adjacent steel reinforced columns, and primarily fixing; and finally fixedly welding the steel reinforced beam to the steel reinforced column to form a steel reinforced frame so as to finish the mounting of the steel reinforced concrete steel skeleton.
Description
technical field [0001] The invention relates to a method for installing a steel skeleton, in particular to a method for installing a steel-reinforced concrete steel skeleton of a large-scale metallurgical industrial factory building, and belongs to the technical field of factory building construction and production. Background technique [0002] Steel reinforced concrete frame structure is a new type of building structure developed after steel structure and concrete structure. It combines the advantages of steel structure and concrete structure. Compared with steel structure, steel reinforced concrete structure can improve the overall and Local yield performance, increase structural rigidity and damping, save steel, anti-rust and anti-corrosion; compared with concrete structure, embedded steel skeleton can improve the bearing capacity of the structure, reduce the cross-sectional size of components, increase the building usable area, and enhance shear performance and bending ...
