Embedded parts
It is the fixed purpose of connecting structural members or non-structural members by leaving steel plates and anchoring bars in the structure. For example, connectors for post-process fixing (such as doors, windows, curtain walls, water pipes, gas pipes, etc.). There are many places where concrete structures and steel structures are connected.
Embedded pipe
Pipes (usually steel pipes, cast iron pipes or PVC pipes) are left in the structure to pass through the pipes or leave holes for the passage of equipment. For example, it is used in various pipelines in the later stage (such as strong and weak electricity, water supply, gas, etc.). Commonly used for pipe preparation holes in concrete wall beams.
Embedded bolts
In the structure, the bolts are pre-embedded in the structure at one time, and the bolt threads left on the upper part are used to fix the components, which play the role of connection and fixation. The common ones are reserved bolts for equipment.
