Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel reinforcement stirrup for building engineering. Background Technology

[0002] Currently, at construction sites, during the construction of steel reinforcement projects, supports are needed to stabilize the upper and lower layers of steel reinforcement in concrete slabs. This requires the use of steel stirrups, which are shaped like stools and are commonly known as stirrups or bracing bars. They are used between the upper and lower layers of steel reinforcement to fix the upper layer of steel reinforcement.

[0003] However, there are still some shortcomings in the steel reinforcement stirrups currently in use. Due to the varying conditions at different construction sites, the spacing between the upper and lower layers of steel reinforcement in concrete slabs differs. For these different spacing layers, specially customized steel reinforcement stirrups are required for support. Since the currently used steel reinforcement stirrups cannot be height-adjusted, if the dimensions are unsuitable, the upper and lower layers of reinforcement cannot be stably supported and fixed, potentially leading to construction hazards and affecting the construction progress. Therefore, this application provides a steel reinforcement stirrup for building engineering. Utility Model Content
