Reinforced concrete engineering This chapter mainly introduces the construction technology and construction methods of the three sub-projects of reinforced concrete engineering. It is required to master the construction characteristics and classification of concrete engineering, the types and properties of steel bars, the principle of the joint work of steel bars and concrete, and the structural requirements of the formwork. Master and be familiar with the construction process and construction technology of reinforced concrete engineering, the cold drawing of steel bars, the calculation of steel bar batching and replacement, and master the inspection and evaluation of concrete quality and the handling of quality accidents. It is the focus, difficulty and key part of learning this chapter. Teaching process or content Teaching method points This chapter mainly introduces the whole construction process of cast-in-place concrete structure engineering in detail, because the current building structure mostly adopts cast-in-place or assembled prefabricated integral concrete structure, and the construction requirements for formwork, steel bars and concrete engineering are more stringent. Because the content of this chapter in the textbook is too simple, in order to deepen students\' more comprehensive grasp of this part of the content, it should be introduced in combination with the links and quality common problems that are easily overlooked at the construction site and the textbook. Concrete structure: plain concrete structure, reinforced concrete structure, prestressed concrete structure, etc. Reinforced concrete structure refers to a building structure or component that is made by compounding steel bars and concrete according to design requirements and casting them using formwork. Concrete is a mixture of cement, coarse aggregate, fine aggregate, water, admixtures, etc. mixed in a certain proportion, which is cast into shape (moldability) by formwork casting and then cured and hardened to form an artificial stone. Reinforced concrete structure engineering: steel bar engineering, formwork engineering, concrete engineering. The construction process of reinforced concrete engineering is shown in the figure below: Reinforced concrete structure engineering construction flow chart
