Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and in particular to a mold for a prefabricated floor slab. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as beams, floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, then transported to the construction site, and assembled and installed on site through reliable connection methods. The existing technology fixes the mold into shape, arranges the steel bars in the mold casting groove, applies a release agent to the mold, and then pours concrete to form a prefabricated floor slab. After a floor slab is formed, it is demolded, and then the mold is cleaned and produced again.

[0003] The problem with the existing technology is that the prefabricated floor needs to cast structures such as wire ducts and wire box ducts according to design requirements, and the structure relies on auxiliary accessories such as core parts. Multiple floor slabs are spliced ​​to form the entire floor plane, so the positions of wire ducts and wire box ducts in different positions of the floor slabs are also different, so the mold needs to be adjusted to the assembly position of the accessories.

[0004] However, the structure of the existing mold requires the entire mold to be disassembled and replaced in order to set accessories at different positions.
