Description

[0002] In reinforced concrete structure construction, the traditional pad is mainly used to support the bottom reinforcement to ensure that the thickness of its bottom protective layer meets the design requirements. However, for multi-layer reinforcement arrangement, especially the spacing between the two rows of reinforcement, the traditional pad cannot effectively control the stability of the spacing. When using beam pad iron and other methods, it is easy to cause reinforcement and reinforcement phenomenon, thereby weakening the gripping force between the reinforcement and the concrete, affecting the stress performance and structural safety of the member. In addition, since the traditional concrete pad is mostly set as a columnar pier, its contact surface with the reinforcement or water and electricity pipeline is a plane, and the positioning effect on the water and electricity pipeline and the reinforcement is poor during concrete pouring, which causes the pipeline or reinforcement to be easily displaced during pouring, affecting the precision of pipeline arrangement and engineering quality.
