Problems solved by technology
However, due to the lack of an effective focus point in the process of hoisting and correction, it cannot be positioned completely at one time, and it takes a long time to keep the upper steel column in a suspended posture, so that the construction hoisting system must be in a full-load state for a long time, and there may be problems during the construction process. Due to the impact of strong wind and surrounding construction vibration, when the steel columns are assembled and welded, the steel columns may be shifted or misaligned
At the same time, in the above structural system, the stressed components such as the jack near the lower steel column are only used to support the force and fix the lower steel column, and do not fully exert their additional functions
In addition, after the steel columns are butted, if continuous welding is used, it is easy to cause uneven stress distribution in the joint structure, which will affect the quality of the steel column assembly and welding

The invention discloses an upper and lower steel column abutting structure system which comprises an upper steel column, a lower steel column and a plurality of stiffening plate suites, wherein the upper steel column and the lower steel column are coaxially and vertically abutted; each stiffening plate suite at least comprises one upper stiffening plate and one lower stiffening plate; the upper steel column and the lower steel column are connected by the upper stiffening plates; the upper steel column and the lower steel column are also connected by the lower stiffening plates; upper ejector plates and lower ejector plates which are opposite and are used for being ejected by external jacks are respectively arranged on the upper stiffening plates and the lower stiffening plates; and abutted ports of the upper steel column and the lower steel column are welded. The invention also discloses a one-time installing and fixing method of the upper and lower steel column abutting structure system, which comprises the following steps of firstly, welding the lower stiffening plates and vertically arranging the steel columns; then welding the upper stiffening plates; regulating the postures of the steel columns by the jacks; and finally, welding each stiffening plate suite and a steel column joint. The upper and lower steel column abutting structure system and the one-time installing and fixing method thereof can be widely used in the field of building construction.
Description
technical field [0001] The invention relates to a structure system in which upper and lower steel columns are docked, positioned and corrected in the field of building construction, and a corresponding installation and fixing method thereof. Background technique [0002] At present, due to the large size and heavy weight of the steel columns without cable wind ropes in the field of construction, the method of assembly and docking is generally hoisting at the upper part, correcting and adjusting the jack at the lower part, and then seam welding and strengthening the connecting ribs. The method is connected and reinforced to form a butt joint structure system of upper and lower steel columns. However, due to the lack of an effective focus point in the process of hoisting and correction, it cannot be positioned completely at one time, and it takes a long time to keep the upper steel column in a suspended posture, so that the construction hoisting system must be in a full-load s...
