Plane construction drawing
The overall design method of structural construction drawing plane is called "flat method" for short.
Flat method is a kind of drawing method to express structural size, elevation, structure and reinforcement. Use the plane, this is the structural construction drawing for the building. Pingfa has a special picture book, which is to be learned.
In the past, the structural construction drawings all had the expression of cross-section, that is, the components in the structural drawings were separated by cross-section, and the cross-section size and reinforcement size of the components were reflected by cross-section. However, the information expression is repetitive and messy, and it is basically not used on a large scale now, but only appears as a supplement in the structure diagram. Later, in the 1990s, a table with beams appeared in Guangdong, which was specially designed for many beams. All the information of beam components is filled in as blank, and then the structural diagram of beam components is established on it, thus forming the beam table. Although it saves a lot of repetitive information compared with the profile, it is easy to make mistakes when filling in the beam table, and the data is piled up, which is easy to fill in and not intuitive. In addition to small-scale use, it is necessary to check the beam table against the structural layout.
Now it is in line with international standards, that is, Pingfa, which is a common language. Component information (section, reinforcement, span, quantity, etc.). ) directly marked on the structural plan, the whole is directly shown on the structural plan of each component, and combined with the standard structural details, a new complete structural design is formed. It changes the traditional tedious method of drawing reinforcement details one by one by drawing structural plane layout.
