The main drawings are: structural design description, structural plan layout (basic plan, column net plan, floor structure plan, roof structure plan and structural details (base section, staircase construction drawing, columns, beams, etc. Reinforcement diagram). Referred to as "King Shi"

3. Equipment construction drawing

Drawings mainly expressing the layout and construction requirements of equipment for water supply and drainage, heating, ventilation, power supply and lighting of steel structures.

Therefore, the equipment construction drawing is divided into three types of drawings:

1) Heating and ventilation construction drawing: the drawings mainly showing the requirements of the pipeline layout and construction and installation. Including pipeline layout plan, pipeline system drawing, pipeline installation detailed drawing and legend and construction instructions.

2) Water supply and drainage construction drawing: a drawing showing the layout and spatial orientation of the water supply and drainage pipeline, the method of pipeline and accessories, and the processing and installation requirements. Including pipeline layout plan, pipeline system drawing, pipeline installation detailed drawing and legend and construction instructions.

3) Electrical construction drawing: a drawing mainly showing the direction of electrical wiring and installation requirements. Including line layout plan, line system drawing, line installation detailed drawing and legend and construction instructions. Referred to as "facilities".

3. Arrangement order of construction drawings

In order to facilitate reference to drawings and file management, and to facilitate construction, a complete set of house construction drawings are always arranged and bound in a certain order. For professional drawings, the following requirements should be followed during the layout:

1. The basic drawing is in the front, and the detailed drawing is in the back;

2. The construction first, the construction second;

3. The important is first, and the second is last.

The arrangement sequence of a complete set of house construction drawings is as follows:

1. Homepage

The homepage drawing lists the catalogue of drawings. In the catalogue of drawings, the names, number, and location of the drawings of various professional drawings reflect the arrangement sequence of a complete set of construction drawings for easy search.

2. General description of design

1) The basis of engineering design: steel structure area, cost per unit area, relevant geological, hydrological, meteorological and other aspects.

2) Design standards: steel structure standards, structural load levels, seismic fortification standards, heating, ventilation, lighting standards, etc.

3) Construction requirements: construction technical requirements; steel structure material requirements, such as cement grade, concrete strength grade, brick grade, reinforcement grade, cement mortar grade, etc.

3. Construction drawing of steel structure

1) General plan

2) Steel structure plan (bottom floor plan, standard floor plan, top floor plan, roof plan)

3) Steel structure elevation view (front elevation view ~ back elevation view ~ side elevation view)

4) Steel structure profile

5) Steel structure details (kitchen and toilet details, roof details, exterior wall details, stairs details, doors and windows details, installation node details, etc.).

4. Structural construction drawing

1) Description of structural design

2) Basic plan and detailed drawing

3) Structure plan (floor structure plan to roof structure plan)

4) Detailed drawing of the component (construction drawing of stair structure ~ reinforcement drawing of cast-in-place component).

5. Water supply and drainage construction drawing

Pipeline plan, pipeline system drawing, detailed pipeline processing and installation drawings, legends and construction instructions.

6. Construction drawing of heating and ventilation

Pipeline plan, pipeline system drawing, detailed pipeline processing and installation drawings, legends and construction instructions.

7. Electrical construction drawing

Line plan, line system drawing, line installation details, legends and construction instructions.

4. House construction drawing

1. Most drawings are drawn by orthographic method.

2. The drawing ratio commonly used in basic drawings is 1: 100, and 1:50 or 1: 200 can also be used. The drawing ratio of the general plan is generally 1: 500, 1: 1000 or 1: 2000;

The drawing scale of the detailed drawing is larger, such as 1: 2, 1: 5, 1:10, 1:20, 1:30, etc., relative to the size of the steel structure, it should be reduced when drawing.

3. Use legend symbols to represent the structure, accessories and materials of the house: due to the small scale of drawing, the structure, accessories and materials of the house are all represented by legend symbols. To read the construction drawings of the house, you must be familiar with the relevant legends of the steel structure.

5, reading method

1. Basic requirements

1) Have basic knowledge of orthographic projection and master the basic laws of orthographic projection of points, lines and planes.

2) Familiar with the meanings of legends, symbols, line types, sizes and proportions commonly used in construction drawings.

3) Familiar with the basic situation of the composition and structure of houses for various purposes.

2. Reading method

When reading, start with the overall situation, and follow the order of construction drawings, from thick to thin, and read back and forth.

1) First read the first page drawing: from the drawing list on the first page drawing, you can know what kind of professional drawings the house construction drawing consists of, how many drawings of each professional drawing, the drawing name and drawing number of each drawing.

2) Read the general description of the design: from which you can understand the basis of the design, the design standards and the basic requirements in the construction, as well as the content that the designer thinks should be explained, not drawn in the picture.

3) Steel structure construction drawings-structure construction drawings-equipment construction drawings are read one by one in order.

4) In the reading of various professional drawings, the basic drawings and detailed drawings should be read in comparison, and the main content represented by the professional drawings should be clearly seen.

5) If there is a contradiction between the construction drawing of the steel structure and the construction drawing of the structure, the construction drawing of the structure shall prevail (component size) to ensure the strength and construction quality of the steel structure.
