Integral outer side concrete formwork

The invention discloses an integral type outer side concrete formwork, and relates to the technical field of concrete formworks, the integral type outer side concrete formwork comprises a concrete formwork body, an extension assembly is arranged at the top of the concrete formwork body, a detection assembly is arranged on the side face of the concrete formwork body, the concrete formwork body comprises a main formwork body, and a plurality of inserting holes are formed in the top of the main formwork body. The extension effect can be provided through the first extension plate, the insertion columns and the insertion holes in the top of the concrete formwork are used for insertion connection, and the side supporting blocks are matched with the side supporting strip plates to further provide the supporting effect towards one side, so that the lateral supporting force of the first extension plate is improved; the second extension plate can be continuously increased and lengthened on the first extension plate, th
