Drawing Codes for House Prefabricated Slabs
Common drawing codes for house prefabricated slabs include: Slab (B), Roof Slab (WB), Hollow Slab (KB), Channel Slab (CB), Folded Slab (ZB), Ribbed Slab (MB), Stair Slab (TB), Cover Slab or Trench Cover Slab (GB), Rain Shield Slab or Eaves Slab (YB), Crane Safety Walkway Slab (DB), Wall Panel (QB), and Gutter Slab (TGB). Here is a detailed explanation of these codes:
Slab (B): This is the most basic type of prefabricated slab, typically referring to an ordinary flat slab component used in building floors, ground surfaces, and other parts. It features a simple structure and convenient construction.
Roof Slab (WB): A prefabricated slab specifically designed for roofs, capable of bearing the roof load and providing waterproofing and thermal insulation functions. It is an important part of the building roof structure.
Hollow Slab (KB): A prefabricated slab with internal cavities, which allows it to maintain a certain strength while reducing its self-weight and improving material utilization. It is one of the more common types of prefabricated slabs.
Channel Slab (CB): Its cross-section is shaped like a channel, which gives it good mechanical properties when bearing loads. It is often used in building parts that require large spans.
Folded Slab (ZB): Formed by folding multiple flat slabs to create a certain spatial structure. Folded slabs are often used in building parts that require special shapes or spatial effects.
Ribbed Slab (MB): Dense ribs are set inside the slab to enhance its load-bearing capacity and stiffness. Ribbed slabs are suitable for building parts that require high load-bearing capacity.
Stair Slab (TB): A prefabricated slab specifically designed for stairs, capable of bearing the load of people walking on the stairs and ensuring the stability and safety of the stairs.
Cover Slab or Trench Cover Slab (GB): A prefabricated slab used to cover trenches or openings, providing protection, closure, and aesthetic appeal.
Rain Shield Slab or Eaves Slab (YB): Installed at the eaves of buildings to block rainwater and protect the exterior walls from rain erosion.
Crane Safety Walkway Slab (DB): A prefabricated slab that provides a safe walking path for cranes, ensuring the stability and safety of cranes during operation.
Wall Panel (QB): A prefabricated slab used for building walls, capable of bearing the load of the walls and providing thermal insulation and sound insulation functions.
Gutter Slab (TGB): Installed at the gutters of building roofs to collect and discharge rainwater, preventing water accumulation on the roof.
