Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0020] The column of the old steel structure industrial factory building is generally composed of upper and lower sections, the lower section is a double steel column, and the upper section is a single steel column. The upper section of the side column and the center column of the plant are different in structure, while the lower section is basically the same.

[0021] Middle column: L1=L2, that is, the distance between the center of the single steel column in the upper section and the center of the double steel column in the lower section is equal, which is a symmetrical structure. The centers of the driving beams on both sides coincide with the centers of the double steel columns respectively.

[0022] Side column: L1>L2, that is, the distance between the center of the single steel column in the upper section and the center of the double-row steel column i...

Abstract

An online rapid transformation method for changing a side column into a center column of an old steel structure industrial factory building is characterized by comprising the following steps of adding a column (2) to the lower section of a factory building column to meet the requirements of crane beam and rail installation; performing local modification on the upper section of single steel column, wherein a flange plate arranged on one side of the upper section of single steel column is cut for a certain distance towards the direction of a web to enable the distance between a new flange plate (5) which is locally shifted and the center of a new rail to be equal to the distance between the original flange plate arranged on the other side and the center of the existing rail and accordingly the smooth driving of vehicles can be ensured; adding a rib plate (4), meanwhile blocking a man hole (6) located between the new flange plate (5) and the rib plate (4) through a steel plate and connecting the new flange plate (5) with a man hole side plate through a high strength bolt (7). According to the online rapid transformation method for changing the side column into the center column of the old steel structure industrial factory building, the transformation investment of the factory building is saved, the speed is high, the production recovery is early and the engineering quality is safe and reliable.

Description

technical field [0001] The invention relates to a method for transforming an old steel structure factory building, in particular to an on-line rapid transformation method for converting side columns into center columns of an old steel structure industrial factory building. Background technique [0002] With the continuous updating of unit production line equipment, continuous improvement of production technology, continuous expansion of production capacity, and increasing output, the capacity of the material storage area in the old steel structure industrial plant can no longer meet the actual demand. For the old steel structure industrial factory buildings with two spans or more, when the length of the span and the factory building are not equal, the span of the factory building with a shorter length will be extended and expanded, and the columns of some old factory buildings will be changed from side columns to central columns. See figure 1 Columns 112, 113, and 114 of col...
