The invention relates to a method for replacing a column by supporting the roof. The method comprises the following steps of: (a) arranging a temporary bracket near a steel column of a plant, wherein the temporary bracket is used for supporting a carrier under the roof and reinforcing the carrier; (b) dismantling a crane beam and a crane beam brake system on the steel column of the plant, cutting the steel column of the plant by using a parting tool and then dismantling the steel column of the plant; (c) arranging a framework column at the position located by the original steel column of the plant and then arranging the crane beam and the crane beam brake system on the framework column; and (d) dismantling the roof on the upper part of the carrier and perfecting the expanded project. The method has convenient operation, high safety and low cost and reduces the influence on production environment.
Description
technical field [0001] The invention relates to a building construction method, in particular to a method for supporting a roof and changing columns. Background technique [0002] A steel factory decided to build a new converter in the original converter steelmaking plant. Therefore, the original plant needs to be rebuilt. First, the first phase of the renovation requires the replacement of the steel columns under the original roof, and the replacement is completed within a limited time to reduce impact on production. In the second phase, we will improve the content of the upper part of the transformation. The existing building expansion method generally adopts to demolish the original building and the objects around the original building, and then expand and build a new building project at the position of the original building and its surroundings. We know that buildings are generally made of reinforced concrete, etc. It is very laborious to completely dismantle them, req...
