Technical Field

[0001] The invention relates to the technical field of building components, in particular to a special-shaped concrete pad. Background Art

[0002] In construction projects, in order to strengthen the strength of concrete structures, before pouring concrete, usually prefabricated and tied steel bars are used as the skeleton of the concrete structure. Then the concrete is poured and the steel skeleton is wrapped in the concrete structure. In the production of concrete structures, usually the steel skeleton is tied first and then concrete is poured on the steel skeleton. In order to make the steel skeleton located in the middle of the concrete structure, a concrete pad is needed under the steel skeleton. However, in the existing steel bar laying process, since the distance between the steel bar and the laying surface is not completely fixed, and the height of the concrete pad is mostly fixed, it is sometimes necessary to purchase pads of different models, which brings certain troubles to the construction.
