Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "inner", "outer", "left", "right" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1-7, the utility model discloses a welding-free and perforation-free formwork opposite-pulling system of a steel reinforced concrete column, which takes an I-shaped steel as an example, wherein the middle part of the concrete column is provided with first cross beams 4 respectively arranged at the outer parts of two wing plates of the steel reinforced concrete column in the direction perpendicular to the wing plates, the two first cross beams are connected through first screw rods 2, and the two ends of the first screw rods extend to the outer parts of the first cross beams and are respectively fastened by nuts.
