Climbing thermal insulation device and construction method for jacking platform of high-rise building core tube

Abstract

The invention provides a high-rise building core tube jacking platform climbing and thermal insulating device and a construction method thereof. The climbing and thermal insulating device comprises a jacking platform and hanging racks hung onto the lower portion of the jacking platform. The bottom ends of the hanging racks are provided with climbing and heat insulating structures for conducting heat preservation on vertical structures formed through pouring. By adopting the climbing and thermal insulating device, band molds are formed on the vertical structures of a core tube to maintain the vertical structures in time after construction of the vertical structures, so that the vertical concrete maintenance progress keeps up with the construction and building speed of the vertical structures, and the concrete quality of the vertical structures 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. The horizontal structure and vertical structure of the super high-rise core tube structure are often constructed separately. The vertical structure of the core tube adopts a self-climbing formwork system-integral roof Lift the platform. [0003] Can be used with reference figure 1 As shown, the overall jacking platform realizes the construction of the vertical structure through the lower hanger body, and the lower hanger body is divided into steel structure construction layer N+2, steel bar construction layer N+1, and concrete pouring layer in terms of verti...

AI Technical Summary

Problems solved by technology

[0004] However, the fastest speed for vertical structure construction on the overall jacking platform can reach 3.5 days per floor, which makes the molded maintenance time (especially in winter) for the construction of vertical structure walls far from keeping up with the construction speed. Therefore, the maintenance time of the lower vertical structure wall after multiple climbs in a short period of time under the jacking platform is far from meeting the construction requirements, and the concrete quality of the vertical structure is difficult to be guaranteed
