Abstract

The invention discloses a vertical construction seam construction method of a core tube bottom board for a super high-rise and relates to the field of building construction. The construction method includes the strengthening steel bar construction step, the punching-resistant H-shaped steel construction step, the lateral steel bar mesh construction step, the punching-resistant steel bar construction step, the rubber water stop construction step and the grouting construction step. The construction method is reasonable in design; the core tube bottom board of a tower is provided with vertical construction seams, and the core tube bottom board of the super high-rise is subjected to vertical sectional construction, so that the construction progress can be accelerated, the exposure time of a deep foundation pit is shortened, and risks are reduced; besides, the construction rate can be improved, and the labor input can be reduced; by using punching-resistant type steel as the primary punching bearing component and using punching-resistant steel bars, strengthening steel bars and a grouting system as auxiliaries, the high construction efficiency of the core tube bottom board for the super high-rise is guaranteed, and a powerful safety guarantee is provided for constructors.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for constructing vertical construction joints on the bottom plate of a super high-rise core tube. Background technique [0002] In recent years, the height of buildings has repeatedly hit new heights, the volume of projects is increasing day by day, and the construction schedule of projects is tight. For super high-rise buildings, towers are often on key construction routes, and the construction period is relatively long. It is necessary to ensure the progress and safety of the construction, and at the same time, prevent uneven settlement of the floor and avoid serious damage to the construction joints. [0003] Generally, in order to ensure the quality of the bottom slab concrete and reduce the risk of water seepage in the bottom slab of super high-rise buildings, integral construction is adopted. However, this construction method takes a long time and the...
