HG/T 20588-1996 Unified regulations on the content and depth of construction drawings for chemical buildings and structures
Some standard content:
1 General Provisions
1.1 General Principles
1.1.1 These provisions are formulated to unify the content, depth and representation methods of construction drawings for buildings and structures in the chemical industry, so as to improve the design quality and speed up the design progress. 1.1.2 In addition to these provisions, the preparation of construction drawings for buildings and structures shall also comply with the "Uniform Standard for Building Drawings" (GBJ1-86), "Architectural Drawing Standard" (GBJ104-87), and "Architectural Structure Drawing Standard" (GBJ105-87).
1.1.3 The preparation of construction drawings shall be complete in content, convenient for construction, compact and reasonable, with appropriate proportions, complete sizes, neat fonts, and neat and beautiful appearance.
1.1.4 Construction drawings shall be represented in graphics and covered with necessary textual explanations. The sentences shall be concise, fluent and accurate, and there shall be no possibility of multiple interpretations or misunderstandings. 1.1.5 The instructions and drawings attached to these provisions are examples of the depth and representation methods of construction drawings, and shall not be used as the basis for design or construction.
1.1.6 These regulations are only applicable to the design of general new construction, reconstruction, and expansion projects in China. In addition to complying with these regulations, foreign-related projects may also supplement or delete them according to specific circumstances. 1.1.7 In order to improve design efficiency and avoid duplication of work, national standard drawings, local or industry standards and unified engineering nodes should be reused as much as possible to reduce the number of drawings; on the premise of clear expression and convenient construction, methods such as tables and symmetry can be used to simplify drawings.
1.2 Principles of drawing arrangement
1.2.1 Architectural and structural drawings should be prepared separately. When the project is small and there are less than 6 architectural or structural drawings, the architectural and structural drawings can be prepared together.
1.2.2 Reinforced concrete structure and steel structure drawings should be prepared separately. When there are less than 6 steel structure drawings (such as a small number of steel platforms, steel brackets, etc.) or less than 6 reinforced concrete structure drawings, they can also be prepared together. 1.2.3 When architectural and structural drawings are compiled together, the order of arrangement is architectural drawings first and structural drawings later. However, buildings, reinforced concrete structures and steel structures should not be arranged on the same drawing. 1.2.4 The order of arrangement of drawings should follow the following principles: (1) Drawing catalog: The content of the drawing name must be consistent with the title of each drawing, including the catalog of standard drawings and reused drawings. The table format can refer to Table 1.2.4. 1

(2) Home page or project description: The content of the compilation can be found in Sections 2.2, 3.3, 4.3 and 5.2 of this regulation. (3) Drawing arrangement principle:
Plan view is in front, elevation view and section view are in the back. Plan, elevation and section view are in front, and detailed view is in the back. The first construction is in front, and the later construction is in the back. For example: the foundation drawing is in front, and the upper structure drawing is in the back. The main components are in front, and the secondary components are in the back. 1.2.5 The layout of the construction drawings should be arranged from left to right and from bottom to top according to the content of the drawing. When the floor plan or structural layout of a multi-story building is drawn on one drawing, it is advisable to arrange it from bottom to top and from left to right according to the level.

1.3.1 For large and medium-sized projects (including multiple individual projects), it is advisable to prepare a general project description. 1.3.2 Contents of the general project description:
1.3.2.1 Design basis
(1) Level 1 approval documents, construction unit's entrustment documents and contracts, etc. (2) Engineering geology and hydrogeology conditions: geological structure, soil properties (including physical and mechanical properties of base soil, whether there are faults, fracture zones, karst caves, underground rivers, quicksand, whether liquefaction is possible in earthquake zones, etc.), foundation bearing capacity: highest and lowest groundwater levels: freezing depth, whether groundwater is corrosive, etc. (3) Meteorological conditions: basic wind pressure, dominant wind direction, basic snow pressure, relative humidity, highest and lowest temperatures, maximum rainfall, etc. (4) Seismic fortification intensity and seismic fortification intensity of each individual project. 1.3.2.2 Names, drawing numbers and adopted structural forms of the individual projects included in the project. 1.3.2.3 Foundation forms and burial depths of special buildings and structures (including pile foundations). 1.3.2.4 Types, specifications and requirements of major building materials. 1.3.2.5 The national standards, industry standards, local standards and enterprise standards adopted for the project. 1.3.2.6 Special requirements and treatment measures for construction (such as various foundations, anti-skid and anti-slip in landslide areas, earthquake resistance, anti-corrosion, explosion-proof and fire prevention requirements in earthquake areas, etc.). 1.4 Drawing names and component codes
1.4.1 Writing of drawing names
1.4.1.1 The word "drawing" should be added after the drawing name, such as ××× surface drawing, ××× elevation drawing, ××× layout drawing, etc. When the formwork reinforcement drawings of dyeing, columns and frame components are drawn together, the drawing name can be written as the component code, such as L-1, Z-1, KJ-1, etc. When the formwork drawing and reinforcement drawing are drawn separately, the formwork drawing or reinforcement drawing must be clearly stated. 1.4.1.2 The plane drawing uses the elevation to indicate the level, such as soil 0.000 plane drawing, 5.000 plane drawing, 4.980 formwork drawing, etc.
Elevation drawings are marked with axes at both ends, such as ①-elevation drawing, A-elevation drawing, etc. 1.4.1.4
Section drawings should be indicated by Arabic numerals, such as 1-1 section drawing, 2-2 section drawing, etc. 1.4.1.5 Section drawings of components and details should be indicated by Arabic numerals, such as 1-1, 2-2, etc.: Views can be indicated by capital letters, such as view A, view B, etc., and numbered consecutively in the sheet. 1.4.1.6 When the main parts of section drawings or views are the same and only a few parts are different, footnotes can be used to distinguish them, such as \1-1.", "1-1," "2-2", "2-2", etc. 1.4.1.7 When the structural form of a node detail drawing is basically the same as that of a certain node detail drawing, the expression method of a certain detail drawing can be used, such as "reference

".
1.4.2.1 In addition to the component codes specified in the national drawing standards, the following component codes are supplemented: cast-in-place piles
grate plate
steel grating
column foundation
