1, a formal architectural design should be signed by the designer, the person in charge of the architectural drawings, the approver, the proofreader, and stamped with the seal and the registered practice seal.
2. In architectural design drawings, the length is generally in mm, unless otherwise specified; Pay attention to the combination of "building material description" and other drawings when reading drawings. In the "Description of Building Materials", each item is marked with "√", which is the practice adopted in the design. What is not ticked is not the design practice.
3. As shown in the architectural design: "c20 reinforced concrete jl(240400) with 4φ 16 wound φ 6 @ 200 stirrups." The foundation beam of reinforced concrete structure with strength C is 240mm wide and 400mm high. It is equipped with four main steel bars with a diameter of 16mm (16 mm), and a rectangular ring of steel bars with a diameter of 6 mm is hoop every 200 mm (the length of the rectangular ring is about 340-350 mm, and the width is about 180 mm- 190 mm).
4. For example, in architectural design: "c20 concrete column (240240) with 4φ 12 hoop] 6 @ 200." Where "] 6 @ 200" is a nonstandard label and should be "φ 6 @ 200". It is interpreted as: a c20-strength small beam of reinforced concrete structure, with a section length of 240mm and a width of 240mm, is equipped with four main bars with a diameter of 12mm (12mm), and a rectangular steel mesh with a diameter of 6cm is hoop every 200mm. The height of the column depends on the height of the floor marked by the project minus the height of the ring beam and the thickness of the panel, because the ring beam and the panel are poured together.
