What is a precast concrete?
1, concrete embedded parts. According to the functional requirements in the building, it may be necessary to place the iron embedded part in a predetermined position before pouring the concrete. After pouring the concrete, it is fixed in the concrete to expose an iron plate that can be welded. More common in industrial buildings and factories, where equipment needs to be installed.
2, small concrete prefabricated parts. Such as outer window panels, windowsills, concrete ventilation hoods, and decorative concrete lines, etc., are relatively small in size, and it is inconvenient to cast the formwork on the site, so it can be produced on the open ground and transported to designated locations for installation. Usually need to leave a rebar head or embedded parts for welding connections.
