The invention relates to a wood structure anti-shearing connecting element, a connecting structure, a box body platform structure and a construction method. The connecting element is of an integral structure formed by sequentially and vertically bending a metal plate, and comprises a U-shaped web plate, flanges and hook heads, wherein the flanges symmetrically extend out from the two side surfaces of the web plate; the hook heads are formed by bending from the upper end parts of the flanges in a direction of being opposite to the web plate; and connecting holes are formed in each of the web plate, the flanges and the hook heads. The box body platform structure can be used as a lower part support structure for transforming the ground of a stadium into an ice surface; on the premise of not damaging the original field, the temporary transformation in the functional aspect can be fast completed by using the box body structure; and a technical feasible scheme is provided for transforming the existing ordinary stadium into a winter event stadium. By using the connecting element, the stability of the box body structure is ensured; and the reliability of the structure as a whole lower part supporter is ensured; the construction is simple and fast; the time and the labor are saved; and the construction efficiency and the construction quality can be effectively improved.
