Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the following embodiments are combined with the accompanying drawings to specifically explain the operations provided by the present invention.

Please refer to fig. 1, which shows a formwork-free constructional column 1, which comprises a plurality of prefabricated building slabs 3, wherein the plurality of prefabricated building slabs 3 have the same structure and are convex. The constructional column 1 is arranged between two adjacent wall bodies 2, and the side surfaces of the two adjacent wall bodies 2 are connected through the prefabricated building boards 3. A plurality of prefabricated building blocks 3 are symmetrically stacked and built along the inner side and the outer side (the inner side and the outer side refer to the inner side and the outer side which take the wall as a boundary) of the height direction of the constructional column 1, a cavity is formed between two rows of built prefabricated building blocks 3 and the wall bodies 2 on the two sides, the joint of the prefabricated building blocks 3 and the two wall bodies 2 is filled with mortar, and finally concrete is poured into the cavity to pour the prefabricated building blocks 3 and the wall bodies 2 into an integral structure.
