Embodiment Construction

[0020] See Figure 1-7 , the installation method of the roof mast of the present embodiment, comprising: the mast used is a steel pipe assembly 1 with at least 3 sections of steel pipes; The bottom of the outer steel pipe 1-3 is sealed to facilitate the overall vertical lifting of the steel pipe assembly 1; the mast attachment wall base 2 used to support and fix the mast includes at least 3 vertical attachment walls distributed up and down. The two lower ones are: the lowest base 2-1 and the second lowest base 2-2; the highest base 2-4 in the mast attached to the wall base 2 is provided with a pair of manual hoists 4, And the highest base 2-4 is located on the wall adjacent to the top 7 of the roof. The winch 3 used includes: a cable winding motor arranged on the ground and a guide wheel arranged on the top 7 of the roof; the cables connected to the cable winding motor are connected to the steel pipe assembly 1 through the guide wheel. After the cables are bundled with the s...

Abstract

The invention relates to an installing method of a roof mast. The method comprises the following steps: firstly, lifting up a whole steel tube assembly by a windlass; and stopping the windlass when the bottom of the steel tube assembly reaches a base of the lowest place; secondly, connecting a pair of hand-drive block stringers to an outermost layer of steel tube and lifting up or down the steel tube assembly in an alternative working manner in order to fine adjusting the height of the steel tube assembly till the outermost layer of the steel tube is arranged at the base of the lowest place and a base of the lower place, and then keeping the position of the steel tube assembly and welding and fixing the steel tube assembly; connecting the hand-drive block stringers to an innermost layer ofsteel tube in the steel tube assembly, lifting up the innermost layer of the steel tube in an alternative working manner, and stopping the lifting when the length of the sleeved part of the lower endof the innermost layer steel tube and the upper end of an inner layer steel tube sleeved on the innermost layer steel tube is ranged from 0.3-2 m, and then welding and fixing the innermost layer of the steel tube with the inner layer of steel tube; and finally, repeatedly lifting up and welding each remained section of steel tubes sleeved in the outermost layer of the steel tube, and then finishing the installation of the roof mast.

Description

technical field [0001] The invention relates to a method for installing a roof mast, in particular to a method for accumulatively lifting and assembling a sleeved mast. Background technique [0002] The installation of towering structures, especially the masts on the top of buildings, has always been a difficult point in construction, mainly due to the heavy weight and height of the towering masts, and the poor environment of the construction site where there is no large-scale installation machinery. Due to the fact that the lifting performance of the construction machinery cannot meet the lifting height and lifting capacity and other factors, the hydraulic climbing (jacking) method, the pulling method, the scaffolding load-bearing bulk method, etc. are used for construction. Some of these methods have relatively poor construction techniques. Complicated (hydraulic climbing, etc.), some have high labor intensity and high technical requirements (screwing method), and some can...
