Method for constructing combined steel and concrete column of large metallurgy industrial factory building

Abstract

The invention discloses a method for constructing a combined steel and concrete column of a large metallurgy industrial factory building, belongs to the technical field of factory building construction and production, and provides a method for constructing the combined steel and concrete column of the large metallurgy industrial factory building, which can guarantee the manufacturing quality of the combined steel and concrete column. The method for constructing the combined steel and concrete column of the large metallurgy industrial factory building comprises the following steps of: firstly, arranging a steel framework which consists of a steel column and a steel beam on the basis of arrangement, and regulating the arrangement quality of the steel column by arranging a regulation base plate and a cable wind rope; secondly, arranging the outer side of the steel column and the outer side of the steel beam on the steel framework sequentially; then arranging concrete reinforcement on the connection part between the steel column and the steel beam sequentially, and supporting a concrete casting template of the steel column on the outer side of the concrete reinforcement of the steel column, wherein the concrete on the inner side and the outer side of the steel column box body are cast by a high toss and vibrating casting method and a fixed point positioning vibrating casting method; and finally, removing casting template curing concrete after the concrete strength meets the design requirement.

Description

Technical field [0001] The invention relates to a construction method of a steel-reinforced concrete column, in particular to a construction method of a steel-reinforced concrete column of a large metallurgical industrial factory building, and belongs to the technical field of factory building construction 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 performance of steel structure. Local yield performance, increase structural rigidity and damping, save steel, prevent rust and corrosion; compared with concrete structures, the embedded steel skeleton can increase the bearing capacity of the structure, reduce the cross-sectional size of the components, increase the building use area, and enhance t...

AI Technical Summary

Problems solved by technology

[0004] In the construction of workshops, especially large-scale metallurgical industrial steel-reinforced concrete workshops 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. The form of the column connection is particularly complicated, and the installation accuracy of the steel frame composed of steel columns and steel beams is particularly high; in addition, in addition to the steel frame embedded in the concrete, there are densely packed concrete embedded in the outer side of the steel frame. Concrete reinforcement composed of studs, stressed reinforcement and transverse fixed stirrups, which brings many problems to the layout of concrete reinforcement, especially the layout of concrete reinforcement at the joint, and cannot guarantee the layout of concrete reinforcement outside the steel skeleton. quality, which reduces the overall quality of steel reinforced concrete 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. The pouring quality of steel reinforced concrete cannot be well guaranteed. The existing method of pouring concrete columns is also layered pouring , There are cold joints between the layers, which makes the appearance of the poured concrete columns extremely unattractive, so although the steel reinforced concrete frame structure, especially the large metallurgical industrial plant There are many advantages mentioned above, but because of the many technical problems mentioned above in the structure and process of steel reinforced concrete, it has not been widely promoted and applied in existing construction projects, especially in large-scale, high-temperature, and heavy-load conditions. It has never been used in the construction of large metallurgical industrial plants for work
