Description

Fair faced concrete balcony formwork

technical field

The fair-faced concrete balcony formwork is designed for the balcony formwork of the fair-faced concrete structure, and belongs to the field of building construction.

Background technique

Concrete balconies are auxiliary structural parts of housing construction. Most of them are reserved for inserting reinforcement during the construction of the main structure. After the main structure is completely constructed, formwork is supported, steel bars are bound, and concrete is poured; this secondary structure construction method, It makes the construction of reinforced concrete easy, but it will form obvious joint traces at the connection between the balcony and the wall, which is not allowed for the construction of fair-faced concrete structures; if you want no obvious joint traces at the connection between the balcony and the wall, you must During the construction of the main structure, the formwork will be set up at one time, and the concrete will be poured at the same time.
