The suggestions for beginners on how to understand steel structure drawings are as follows:
1. First, you must be familiar with the software. Making steel structure drawings generally requires the use of drawing software such as CAD. You need to be familiar with the software to see some marks.
2. Increase the resolution of the steel structure drawings. For a steel structure drawing, we must first pay attention to the resolution of the drawing. The higher the resolution, the clearer we can see.
3. Print out the steel structure drawings. Generally speaking, you need to print the drawings when viewing them. It is best to print them on A3 paper, because A4 paper is too small and inconvenient to view.
4. You need to be familiar with the relevant structures of steel structures. For steel structure drawings, we need to understand the specific structure of the steel structure so that we can see it more clearly.
5. Make appropriate annotations. Proper marking of important parts or special structural parts in steel structure drawings can be done clearly at a glance.
6. Find a professional to check it out together. If you cannot understand the steel structure drawings, it is recommended that you find a professional who can help you review them.
Steel structure summary:
Steel structure: a structure connected by section steel, such as: steel beams, steel roof trusses, steel towers, steel scaffolding, etc.
Steel structure drawing: a drawing used to represent the steel structure.
Shape steel: Section steel is steel rolled by steel mills according to standard specifications, and its cross-sectional shape and size are fixed.
For example: angle steel, I-beam, channel steel, C-shaped steel, M-shaped steel (patented by Beihai Building Materials Group), H-shaped steel, etc.
Connection methods for medium-section steel in steel structures: welding, riveting, and bolting.
Welding: Heating the connected steel at the connection part to melt it with the welding rod, and then solidify to become an inseparable whole. Weld types: groove weld, fillet weld, plug weld.
Marking of welds: In the steel structure drawings, the location, form, size and auxiliary requirements of the welds must be clearly marked, and do not be careless.
Drawing and labeling when the welds are not connected: When the welds are not connected, a solid line should be added to the visible welds, and a thin grid line should be added to the invisible welds.
Riveting: Using rivets to connect two or more steel plates together.
Bolt connection: Welding and riveting are both non-detachable connections, while bolted connections are detachable connections.
