Manufacture and Application of Prefabricated Board

Precast slab is a floor slab used in early 20th century buildings, and it is a module or plate used in engineering. Because precast concrete is produced and processed in the precast yard and transported directly to the construction site for installation, it is called precast slab. In this paper, the manufacture and use of precast slabs will be discussed in depth to help readers better understand this building material.

manufacturing process

When making precast slabs, the hollow model is nailed with wooden boards first, and then the hollow part of the model is filled with cement after steel bars are laid. When it's dry, knock off the board, and the rest is the prefabricated board.

Multiple uses

Precast slabs are used in many buildings, such as cement slabs covered in ditches beside highways; The cement slab used as thermal insulation layer on the roof is precast slab.

Development of building materials

Now precast slab has been replaced by frame structure and reinforced concrete structure, and its safety and quality have been further improved.
