Description

A prefabricated balcony with liners

technical field

The utility model relates to an assembled building component, in particular to a prefabricated balcony with lining boards.

Background technique

In prefabricated buildings, some prefabricated balconies are usually produced in factories and then prefabricated at the construction site. The joints between the prefabricated balconies and the laminated floors are cast-in-situ concrete to form a structural integrity. In order to strengthen the bonding force between the prefabricated balconies and the laminated floors, shear keyways are usually provided at the tendon outlet ends of the prefabricated balconies. The existing shear keyway is basically formed in the following two ways: first, after the prefabricated balcony is manufactured, the shear keyway is manually or mechanically chiseled at the end of the prefabricated balcony. This method is time-consuming, laborious, inefficient, and easy Destroy the structure of the prefabricated balcony; the second is to design a special mold to form the shear keyway at one time when producing the prefabricated balcony. This method requires additional mold design, so the cost is relatively high.
