Embodiment Construction

[0014] The existing technology is to use steel joists to support the roof system of the factory building. The crane beam and walkway slab system must be dismantled, and the steel crane beam and walkway slab system with the same length as the joist must be rebuilt and installed. Therefore, it takes several months to stop production. . The method of the present invention is to use the lifting beam to directly lift the crane beam, the walkway plate and the roof system above the part of the factory building where the columns are to be extracted. To this end, the supporting bent columns at both ends (that is, the supporting columns at both ends of the steel lifting beam) and the column foundation are first reinforced, and corbel bosses are added at appropriate positions below the crane beams on both sides of the column. At the same time, two single-piece lifting beams (two "I"-shaped welded steel beams) are produced. After the strength of the reinforced part of the supporting bent...

Abstract

The method for remaking mill building and widening distance between columns under the condition of no-stopping production includes the following steps: strengthening column base of supporting bent frame column and column body, adding corbel projection, making and installing lifting beam, finally cutting off partial column part of bent frame column to be removed below the lifting beam so as to implement said ivnention.

Description

Technical field: [0001] The invention relates to a technical method for building renovation, in particular to a technical method for factory building renovation by removing part of the bent columns of the factory building to form a wide column distance to meet the new production process layout requirements under the condition of non-stop production. Background technique: [0002] In the reconstruction of the old factory building, the too small column spacing of the original factory building often becomes an obstacle to the process layout. In order to expand the column spacing, part of the bent columns must be removed to form a new wider column spacing. For example, removing one of the original 6-meter column spacing can form a 12-meter column spacing space. When extracting the column in the prior art, it must be carried out under the condition of stopping production. The main method is to first make a steel joist support to support the roof truss (that is, the roof system) ...
