Try to compare the difference between Liangping construction drawing and traditional structural construction drawing.

Liang Pingfa's construction drawing shows the section size and reinforcement of the beam on the plan by means of text annotation.

The longitudinal section construction drawing of beam is to cut the beam and express the section size and reinforcement arrangement of the beam in the form of longitudinal section and cross section.

The former is characterized by simple and quick drawing and easy standardization, which greatly saves the workload of designers and meets the needs of modern fast-paced society. However, reading pictures is not intuitive, so it is necessary to have a certain understanding of the flat method and be familiar with the flat method atlas. It is the mainstream construction drawing method now.

The latter is characterized by meticulous intuition, which can be seen at a glance whether it is lofting or calculating the engineering quantity, and can clearly show the problems of steel bar connection that may be encountered in construction. It is difficult for construction workers to read drawings and make mistakes. Disadvantages are tedious drawing, heavy workload and high requirements for designers. It is a traditional drawing method, which has been replaced by plane method at present, but it may be partially used in particularly complex buildings.
