Embodiment Construction

[0023] Such as image 3 , Figure 4 Shown, the erection method of the movable working platform of gas dispersing chimney, it comprises the following steps:

[0024] 1) Prepare at least 8 or more movable work platform supports 12 (generally 8-160, determined according to the size of the cylinder, the larger the cylinder, the more the number of supports; 12 are used in this embodiment; each support 12's upper rod 2, crossbeam 3, and lower rod 9 have been welded and formed, and can also be welded and formed on site); prepare the fixed plate group, and the number of fixed plate groups is more than 1 times that of the movable work platform support 12 (generally 16 -640, present embodiment adopts 24, use alternately; If adopting number is many, then need not use alternately), each fixed plate group is made up of first fixed plate 7, second fixed plate 10;

[0025] Such as figure 1 , figure 2 As shown, the movable work platform support 12 includes an upper pole 2, a crossbeam 3,...

Abstract

The invention relates to a method for setting up an operation platform. The method for setting up a removable operation platform for a gas diffusion chimney is characterized by comprising the following steps: 1) preparing at least more than 8 removable operation platforms, and preparing a fixing plate set; 2) welding first fixing plates with the number corresponding to brackets of the removable operation platforms on the same height on the outer wall of a steel structure cylinder body along the circumference, and welding second fixing plates with the number corresponding to the brackets of the removable operation platforms on the same height on the outer wall of a steel structure cylinder body along the circumference; 3) mounting the brackets of the removable operation platforms; 4) paving platform boards on crossbeams of the brackets of the removable operation platforms; 5) threading annular safety curb chains at the upper end parts of upper rods of the brackets of the removable operation platforms to form an integral operation platform; and 6) after the steel structure cylinder body is raised, repeating 2) to 5) on the prior first fixing plates till the mounting of the steel structure cylinder body is finished. The method has the characteristics of simple structure, convenient use and high flexibility.

Description

technical field [0001] The invention relates to a method for erecting a working platform, which is mainly applicable to the installation of taller steel structure cylinders, the most typical structure being blast furnace venting chimneys, and applicable to any other steel cylinder buildings with similar structures. Background technique [0002] At present, scaffolding is used for the installation of the steel structure of the cylinder, and the platform board is placed on the scaffold; the scaffold is usually built from the foundation to the top of the steel structure of the cylinder, and the number of components that constitute the scaffold is large, which makes transportation, loading and unloading very inconvenient. Contents of the invention [0003] The object of the present invention is to provide an easy-to-use and flexible method for erecting a movable working platform for a gas-dissipating chimney. [0004] In order to achieve the above object, the technical solutio...
