Embodiment Construction

[0021] figure 1 It is a schematic diagram of the hoisting of the converter tower, figure 2 It is the steel structure diagram of the converter tower, as shown in the figure. A two-way hoisting construction method for a steel structure of a converter tower. The converter tower has seven floors, including a converter span 1 and a feeding span 2. The construction includes the following steps:

[0022] a. Use tower crane 3 to hoist the steel column from the first floor to the fourth floor 7. The frame beam of the fourth floor 7 is hoisted by the truck crane. After the frame beam of the fourth floor 7 is installed and welded, immediately lay the platform slab and steel column During the upward construction, the main frame beams are installed to form a steel bent frame, which forms a stable unit system in space, meets the rigidity and stability requirements of the upward installation of steel columns, and ensures the safety of construction. The fourth floor 7 divides the entire se...

Abstract

The invention discloses a method for the two-way hoisting construction of a converter tower steel structure, which comprises the following steps of: firstly, performing construction from a first layer to a fourth layer in a mode of hoisting steel columns by using a tower crane, hoisting a frame beam on the fourth layer by using a truck crane, and after the frame beam on the fourth layer is weldedcompletely, paving a flat pallet immediately, so that an integral converter tower with seven layers is divided into an upper part and a lower part; secondly, for the upper part, performing layer-by-layer construction from bottom to top by adopting a forward hoisting method in a mode of hoisting the steel columns and the frame beam by using the tower crane; and finally, for the lower part, performing the layer-by-layer construction from top to bottom by adopting a backward hoisting method which is synchronous with the forward hoisting method in a mode of hoisting the frame beam by using the truck crane. In the method, starting from a platform of the fourth layer, platforms on the upper part of the converter tower are constructed by utilizing the tower crane, platforms on the lower part of the converter tower are hoisted by utilizing the truck crane to push towards the next layer, and the construction and installation are performed simultaneously by a method of combining forward hoisting and backward hoisting to form a dual working face, so that the efficiency is improved greatly, and the construction period is shortened.

Description

technical field [0001] The invention relates to a construction method for a steel structure of a converter tower, in particular to a two-way hoisting construction method for a steel structure of a converter tower. Background technique [0002] In the construction of metallurgical steelworks, the amount of steel structure accounts for more than two-thirds of the entire project. The organization and implementation of the steel structure project is the key to the success of the entire project, and the tower is the key to the steel structure project of the converter. The most important thing is that a large number of key equipment in the steelmaking project are installed in the tower, so the tower plays the role of the heart in the steelmaking project. [0003] Because a large number of top-down assembly line equipment needs to be installed on the converter tower, therefore, the converter tower is generally designed with seven floors to meet the requirements of the production pr...
