Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template device for a post-cast zone of a basement. Background Art

[0002] Nowadays, many buildings such as commercial housing, hospitals, and comprehensive venues are equipped with corresponding basements as garages or other functional rooms. During the construction process of the basement, settlement strips are often required to provide space for the settlement of the upper main body during construction. Due to the long construction period of the settlement strips, the outer wall of the basement cannot be backfilled, and the external temporary road ring cannot be constructed, which has a great impact on the construction process. The traditional construction method is to set up brick molds on the outside of the outer wall strips. Due to its high construction height, the bottom needs to be stepped to expand the foundation to meet the backfill requirements. This construction method is not only costly and ineffective, but also increases the difficulty of waterproofing construction. It is also necessary to reserve tension screws inside to provide conditions for the subsequent inner formwork sealing, which increases the risk of leakage. Utility Model Content
