Technical Field

The invention relates to a construction method of a constructional column, in particular to a construction device and a construction method of an external filler wall end constructional column without peripheral protection.

Background

At present, with the acceleration of the urbanization process of China, the scales of urban infrastructure, real estate development and shed house area transformation are continuously enlarged, and more building sites are arranged in cities. In the construction process, the peripheral protection system of the high-rise residence adopts more and more construction sites with attached lifting scaffolds, and compared with the traditional floor-type overhanging scaffold protection system, the peripheral protection system has the advantages of safety, quality, attractiveness and material saving. The attached lifting scaffold can be attached to an engineering structure and can climb along with the engineering structure layer by depending on self lifting equipment and devices. However, when the attached lifting scaffold continuously climbs along with the main structure, the structure at the lower part is exposed and lacks peripheral protection, and even if a safety net is arranged to reduce the negative influence caused by falling objects, in the construction stage of the infilled wall, particularly the construction of the wall body at the periphery of the structure and the operation of embedding bars and pouring of related constructional columns, although an operator ties a safety belt, certain risks still occur. Particularly, when an operator plants the steel bars on the upper part of the constructional column at the end part of the external filling wall, the concrete structure can be damaged by punching of the electric hammer, and the operator is very easy to fall off.
