A building structure beam bottom reinforcement device

Technical Field

The utility model relates to the technical field of house construction, and more specifically to a beam bottom reinforcement device for a house construction structure.

Background Art

The pouring of the bottom of the beam of the building structure plays a vital role in the entire construction process. The general steps of its construction are: erecting scaffolding, then setting up the formwork, then reinforcing it with reinforcement devices, and finally pouring concrete; because in the process of pouring concrete, the erected formwork is often insufficiently reinforced, resulting in the appearance of mold expansion during the concrete pouring process. Once the formwork is deformed during the pouring process, it may not only lead to the failure of this pouring, but also cause the poured beam to fail to meet the building construction standards.
