A method for installing steel columns for factory building expansion located at existing pipelines

Abstract

The invention discloses an installing method for factory building extension steel columns at an existing pipeline, and belongs to an installing method for steel structures of factory building extension. The method is characterized in that the steel columns of an extended factory building are divided into upper steel columns and lower steel columns, for column internal supports, inside the lower steel columns, located at the colliding positions of the energy medium pipeline, welding connection is changed into bolt connection, the lower segments of the lower steel columns are provided with n-shaped through grooves, when the lower steel columns are installed, the column internal supports are disassembled at first, then the lower steel columns are inserted downwards in the upper direction of the energy medium pipeline, stride the energy medium pipeline in the mode of bestriding, and then are inserted into a cup rabbet foundation, and after the lower steel columns are installed, the upper steel columns are installed. The method includes the construction steps that 1, installing colliding points of the factory building extension steel columns are sieved; 2, structural design is performedon the steel columns at the colliding points of factory building extension; 3, the steel columns at the colliding points of factory building extension are installed. With the method, the problem is solved that the production energy medium pipeline collides with the steel columns of factory building extension in the process of installation, and costs are lowered.

Description

technical field [0001] The invention belongs to a steel structure installation method for factory building extension, in particular to a method for installing a factory building extension steel column. Background technique [0002] In metallurgical engineering, it is often encountered that due to the owner's initial construction scale or the initial investment capital limitation, the original production workshop space is often insufficient when the subsequent production line process is transformed or the production scale is increased. The current solution to this problem The main way is to expand the original factory building. However, in the original production workshop, in order to meet the needs of producing energy medium, according to the conventional design, the production of energy medium was transported from the energy medium pipeline outside the plant to each production user point through the medium pipe network in the workshop; while most of the plant expansion, Ge...
