Climbing thermal insulation system and construction method for walls under the jacking platform of high-rise buildings

Abstract

The invention provides a heat preservation system for climbing of a high-rise building jacking platform lower wall and a construction method of the heat preservation system. The heat preservation system comprises a jacking platform and a suspension suspended below the jacking platform. The suspension is provided with formworks for forming concrete walls through pouring. A heat preservation device is arranged at the bottom ends of the formworks so as to carry out heat preservation on the concrete walls formed through pouring. By means of the heat preservation system and the construction method, how to carry out formwork maintenance in time after the core tube concrete walls are constructed is achieved, vertical concrete maintenance keeps pace with the concrete construction building speed, and accordingly the concrete quality of the concrete walls is further improved.

Description

technical field [0001] The invention relates to a climbing heat preservation device, in particular to a climbing heat preservation device suitable for the construction of a core tube of a high-rise building and a construction method thereof. Background technique [0002] With the advancement of science and technology and the improvement of construction technology, there are more and more super high-rise large buildings. During the winter construction period in northern my country, the outdoor ambient temperature is very low. According to the requirements of relevant specifications, winter construction measures such as thermal insulation covering that meet the requirements must be taken for the construction of concrete structures. Generally, the core tube of a super high-rise building adopts climbing formwork or an integral jacking platform (top formwork). The vertical wall is constructed ahead of the horizontal structure. The core tube is at a high altitude, with high wind s...

AI Technical Summary

Problems solved by technology

At present, the thermal insulation measures for the core tube wall during the winter construction period are to lay thermal insulation materials on the wall formwork. This kind of measure can only play a role in thermal insulation for the wall concrete of the pouring layer. The construction time of the core wall is very short. When the wall formwork is removed from the mold, it cannot be insulated. The insulation time is short and the overall insulation effect is poor, which will have a certain impact on the construction quality of the wall concrete structure.
