Inner side supporting system and construction structure

The utility model relates to an inner side supporting system and a construction structure, belongs to the technical field of constructional engineering, and aims to solve the problem that an existingadjacent side slope outer wall is difficult to construct. The utility model provides an inner side supporting system which comprises a foundation, the foundation is located at the bottom of an outer wall and is perpendicular to the outer wall, the inner side supporting system comprises supporting units which are arranged in parallel, the plane where each supporting unit is located is perpendicularto the plane where the outer wall is located and is perpendicular to the plane where the foundation is located, and every two supporting units form a group. Each group of supporting units are connected through an X-shaped steel pipe frame, and the supporting units are connected and fixed through steel pipes parallel to the outer wall; the supporting unit comprises N supporting bodies, and N is larger than or equal to 1 an
