A kind of base steel structure column alignment structure with cup mouth and its construction method

Abstract

The invention discloses an alignment structure of a steel structure column with a cup-mouth type foundation and a construction method thereof, comprising a cup-mouth type foundation, a column connected inside the cup-mouth type foundation, and a column connected between the bottom of the column and the bottom surface of the cup-mouth type foundation. A spacer, an adjustment fixture connected to the column and located above the cup-shaped foundation, a stopper connected to the column and located on the top of the adjustment fixture, a jacking device connected to the end of the adjustment fixture and the top surface of the cup-type foundation, and the connection Temporary fixing system in the middle and upper part of the column. By adjusting the setting of the fixture, the present invention can precisely adjust the verticality of the upright column; the setting of the stopper can ensure the upper restraint; the setting of the jacking device facilitates the overall or partial adjustment; The vertical positioning is adjusted in the horizontal direction; the setting of the cushion block is beneficial to adapt to the height difference during installation on the construction site; the setting of the temporary fixing system can be temporarily fixed and assisted in preliminary positioning.

Description

technical field [0001] The invention belongs to the field of column construction, and particularly relates to an alignment structure of a base steel structure with a cup mouth and a construction method thereof. Background technique [0002] In the process of column construction, the fixation with the lower foundation is an important link in the construction. The common fixing methods include ground anchor bolt fixing and "cup type" foundation fixing. The foundation installation with anchor bolts is relatively simple, and the "cup type" foundation installation is more complicated, especially in the horizontal direction of the column. The requirements for positioning and verticality in the vertical direction are relatively strict, so the quality of installation and alignment directly affects the safety of the use structure and service life. At present, most of the cup-shaped foundations are adjusted by hoisting and manual work, but the adjustment accuracy is poor and the oper...
