The invention discloses a super high-rise frame column maintenance method based on an integrated attached lifting scaffold. The super high-rise frame column maintenance method comprises the followingsteps that the attached lifting scaffold is erected on the outer sides of a plurality of concrete frame columns; a main water supply pipe is connected to the attached lifting scaffold, and a PVC pipeis connected to the position, corresponding to the outer side of each concrete frame column, of the main water supply pipe through a branch pipe; after concrete pouring is completed, the PVC pipe sleeves the top of each concrete frame column in a hooped mode and a plurality of water outlet holes in each PVC pipe face the outer wall of the corresponding concrete frame column; a water source is introduced into the PVC pipes through the main water supply pipe to perform watering maintenance on the peripheral vertical surfaces of the concrete frame columns; and after concrete curing is finished, the PVC pipes are collected and placed on the attached type lifting scaffold through a rotary connector and lifted to the set position along with the attached type lifting scaffold. By adopting the super high-rise frame column maintenance method, the maintenance quality and effect are obviously improved.
Description
technical field [0001] The invention relates to a concrete maintenance method, in particular to a maintenance construction method for a super high-rise frame column based on an integrated attached lifting scaffold. Background technique [0002] Modern buildings, especially high-rise buildings, are mostly frame structures, in which beams and columns are the main body of the structure. Therefore, strengthening the quality control of frame structure beams, columns, reinforced concrete and their joints plays a decisive role in improving the overall earthquake resistance, service life and realization of functions of buildings. role. In concrete construction, the quality of concrete products is directly related to vibration and maintenance. The heat of hydration of concrete is very high at the initial stage of pouring, and the water evaporates quickly, which is prone to water shortage. If it is not maintained in time, cracks will appear, which will affect the quality of concrete. ...
