Problems solved by technology
Generally speaking, the steel column foot has been processed in the factory and has a complex structure (steel column foot is an important node, and it is difficult to guarantee the quality on-site). The column is demolished and then re-constructed, which will greatly affect the construction period requirements

Embodiment 1
[0028] Such as Figure 1-5 As shown, the on-site deviation correction method for the steel column foot joint described in this embodiment includes concrete short column 1, column foot anchor bolt 2, column foot anchor bolt head 3, conversion steel plate 4, pre-embedded steel plate 5 and secondary grouting layer 6 , the method is applied to the case where the position of the anchor bolt 2 at the foot of the column does not match the position of the original set node after the pouring of the short concrete column 1 is completed, and the method for correcting the deviation on site of the node includes the following steps:
[0029] Step 1: The pre-embedded steel plate 5 is leveled and elevated according to the installation requirements, and the anchor head 3 of the column foot anchor 2 of the wrong node is removed according to this elevation, and then the embedded steel plate 5 is socketed on the column according to the installation requirements. Foot anchor 2, and the two are wel...

The invention relates to an on-site deviation rectifying method for a steel column base joint, which comprises a concrete short column, a column base anchor bolt, a column base anchor bolt head, a conversion steel plate, an embedded steel plate and a secondary grouting layer, and is applied to the condition that the position of the column base anchor bolt is not consistent with the position of an original set joint after the concrete short column is poured. The pre-embedded steel plate is leveled and elevated according to installation requirements, column foot anchor bolt heads of the column foot anchor bolts of the wrong nodes are cut off according to the elevation, then the column foot anchor bolts are sleeved with the pre-embedded steel plate according to the installation requirements, the pre-embedded steel plate and the column foot anchor bolts are welded together, through holes which coincide with the positions of the original set nodes are formed in the conversion steel plate, and the conversion steel plate and the column foot anchor bolts are welded together. And then the conversion steel plate is welded with the column foot anchor bolt head with the matched length in the through hole where the column foot anchor bolt head is cut off, the conversion steel plate is installed in the column foot anchor bolt, the conversion steel plate and the embedded steel plate are welded together, then a secondary grouting layer is poured between the embedded steel plate and the concrete short column, and the steel column foot is installed.
Description
technical field [0001] The invention relates to the field of construction, in particular to a method for on-site deflection correction of steel column base joints. Background technique [0002] In the construction of industrial buildings, the technology is changing with each passing day, which greatly increases the possibility that the building will face renovation during the whole life cycle. For example, petrochemical, thermal power and other industries often need to upgrade and transform the original process system due to changes in technology and policy. Due to the high strength and toughness of the steel structure, in the factory area of this type of industry, the steel structure bracket is often selected as the supporting structure of the pipeline in the factory area. [0003] The steel structure support generally adopts the combination form of concrete short column pre-embedded column foot anchor bolt and upper steel structure. On-site construction first construct...
