Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated concrete pad. Background Art

[0002] The thickness of the concrete cover of steel bars refers to the distance from the concrete surface to the outer edge of the nominal diameter of the outermost steel bar. If the thickness of the concrete cover is too large, the calculated geometric dimensions of the component will be too small, affecting the bearing capacity of the component; if the thickness of the concrete cover is too small, the steel bars will be exposed after the concrete pouring is completed, and then the carbonization of the concrete will cause corrosion of the steel bars, thereby affecting the appearance and durability of the component. The existing concrete pads are placed directly between the steel bars. When the position of the steel bars moves slightly, the pads may be misplaced, thereby failing to achieve the desired effect. There are no good fixing components and a certain degree of stability is lacking. Utility Model Content
