钢筋及钢筋砼（Steel bar and reinforced concrete） Key words: building that the recommended calculation rules -------------------------------------------------------------------------------- Explain This chapter is divided into concrete and steel, cast member template, template, prefabricated structures, prefabricated single part template pouring five section joint. A, concrete Only 1. concrete column C20 gravel, C20 rubble and C30 prestressedtensioned and C30 prestressed post tensioning section, when used according to the different grade can be included in the design. 2. concrete loss rate was 1.5%, including: production 0.2%, transport 0.8%, forming 0.5%. 3. the appendix lists the consumption quota of concrete strength ratio of the common table for reference. Two, reinforced Within 1. B5 diameter reinforced by spot welding. 2. embedded iron welding factors considered under various conditions. 3. this chapter apply the corresponding reinforcement cage reinforced section, and on the basis of per ton increase of 30KVA AC welder 0.9 classes, 3.5kg welding rod, the other no adjustment. 4. including prestressed reinforced reinforced pre stressing each of the content. Three, template The 1. section is the template according to the different situation, considering the tool type steel template (shaped steel formwork), composite steel formwork, formwork, brick, brick and concrete mode of long line pedestal etc.. 2. cast-in-place reinforced concrete template section, the storey is considered as 3.6m (including the 3.6m). The architectural design of the height of more than 3.6m, calculated as increasing consumption of quantum dots, beams and plates with high number of children to Liang Banchao, wall, column and wall column apply ultra high number of children. As quantum dots do not apply to increase the consumption of the tailgate, pick, along the gutter, stairs and building components. The concrete content of table accessories (Table 1) The name of the accessories The calculation uni
