Embodiment Construction

[0014] The tools and materials used in the construction method of the present invention's core column type towering mast mainly include: 5 to 6 chain hoists of 3 to 5 tons; several sections of steel wire ropes; several sections of steel pipe (or logs) rolling bars; The first grade steel simmers into the hook. Electric welding machine and grinding wheel grinding machine for installation.

[0015] When installing:

[0016] Divided into 4.5~6 meters long core column (round steel or square steel) tied with steel wire rope (or directly welded diameter) 18 grade steel simmered hooks), transported horizontally from the edge of the building. In order to reduce friction and protect the primer, a recyclable steel pipe (or log) roller can be placed under the component;

[0017] After the first core column is transported to the base (steel structure or concrete), use the second and third chain cranes to hang the hooks on both sides of the core column respectively, slowly erect it, and ...

Abstract

The invention relates to towering masts. A construction method for a core column type towering mast comprises the steps that firstly, core columns with the lengths being 4.5-6 m are horizontally transported to a foundation from the edge of a building through a first chain hoist bound on a steel member or a concrete member; secondly, after the first core column is put in place, hooks on the two sides of the first core column are hoisted through a second chain hoist and a third chain hoist correspondingly, the first core column is vertically lifted to the position away from the foundation face by 4.5-6 m, and then operation is stopped; thirdly, the second core column is transported to the foundation through the first chain hoist, hooks on the two sides of the second core column are hoisted through a fourth chain hoist and a fifth chain hoist correspondingly, the second core column is erected and welded to the first core column in a butt-joint mode, the fourth chain hoist and the fifth chain hoist continue to lift upwards, at the moment, the second chain hoist and the third chain hoist are replaced, the hooks are cut off, meanwhile, finish paint brushing of the first core column is finished, and subsequent decoration work is also completed; and fourthly, the second step and the third step are repeated, and thus whole splicing mounting is completed. Safety and convenience are achieved, operation is easy, and the cost is low.

Description

technical field [0001] The present invention relates to towering masts, in particular to stem-type towering masts. Background technique [0002] At present, the tops of many super high-rise buildings or landmark buildings are provided with masts for transmitting TV and telecommunication signals or for lightning protection. Economical; therefore, the more commonly used installation methods are: using a pole-type lifting system that increases with the height and a jacking system that lifts on the base. The rod-type lifting system has defects such as large potential safety hazards and complicated removal and installation of rods; while the jacking installation has high costs and requires professional units and personnel to complete. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a construction method for a core column type towering mast. The invention is safe and convenient, easy to operate, does not need spe...
