Abstract: Formwork-free construction technology has the characteristics of convenience and quickness in construction. It can not only achieve the appearance requirements of the project and ensure the quality of the project, but at the same time, as long as the concrete is poured continuously, the construction period can be greatly reduced; in addition, the construction of masonry At the same time, the corresponding construction operation can be performed on the structural column simultaneously. Practice has proved that compared with the traditional process, the new process operation is uninterrupted and can effectively guarantee the construction quality. Therefore, the construction quality of masonry and structural columns can be improved, while the diffi culty of plastering is simplifi ed, and the voids caused by uneven plastering are prevented. Hidden danger of drum cracking, with high safety. Based on this, this article expounds the support-free formwork construction technology in detail with engineering examples, and looks forward to its future development direction in the construction industry.
