Description
Technical field
The present invention relates to a kind of two sections steel column butt joint location in the realm of building construction, the structural system of correcting, with and corresponding installing and fixing method.
Background technology
At present, no cable wind rope steel column in the realm of building construction, because its volume is big, Heavy Weight, so the assembly unit docking calculation generally adopts the top lifting, bottom jack correction adjustment, the method that adopts seam to weld, install additional strengthened connection bar afterwards again connects reinforces, and forms steel column butt joint structural system up and down.But, owing in the process of lifting and correction, lack effective origin of force, can not one-time positioning complete, getting allows steel column be in the suspention attitude for a long time, make the construction hoisting system must be in full load condition for a long time, the influence of wind-force that may exist in the work progress and periphery construction vibrations during steel column assembly unit welding, may cause the skew or the off normal of steel column in addition.Simultaneously, in the said structure system, near the stressed members such as jack the following steel column are only used for supporting stressed, fix down steel column, do not give full play to its additional function.In addition, after the steel column butt joint,, very easily cause piece structural stress skewness weighing apparatus, thereby influence the assembly unit welding quality of steel column if adopt continuous welding.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of up and down steel column butt joint structural system is provided, and once mounting was fixed after it can make up and down steel column butt joint, reduced the influence of wind-force, vibrations as far as possible, to neutral, verticality is all good.
The present invention also provides a kind of energy the disposable installing and fixing method that has installed and fixed described up and down steel column butt joint structural system.
The solution that the present invention solves its technical problem is:
Steel column butt joint structural system up and down, the last steel column and following steel column that comprise coaxial and vertical butt joint, also comprise a plurality of stiffener external members, each stiffener external member all comprises energetically plate at least and exertes oneself each one of plate, described plate energetically will be gone up steel column and following steel column and be linked together, and describedly exert oneself that plate also will be gone up steel column and following steel column is linked together; At plate energetically with exert oneself on the plate, be respectively equipped with upper plate and lower roof plate relative to each other, that contact for the jack of peripheral hardware; Last steel column is welding with the craft port of following steel column.
As further improvement in the technical proposal, a stiffener external member has energetically plate and exertes oneself each one of plate.A plurality of described stiffener external members are equally spaced around the axis of last steel column.
Then, a kind of described disposable installing and fixing method of steel column butt joint structural system up and down may further comprise the steps:
1), prewelding is exert oneself plate on following steel column, guarantee that steel column is erect under handle after, exerting oneself the lower roof plate of plate is to be positioned under the upper port of steel column down and to be horizontal attitude, exertes oneself the top of plate to stretch out outside the upper port of steel column down;
2), will descend steel column to erect placement fixes;
3), vertically sling and go up steel column, it is moved to and the coaxial position of following steel column, put steel column down and make its lower port dock, form craft port with the upper port of following steel column;
4), on last steel column, weld plate energetically, the quantity of plate and position are corresponding one by one with exerting oneself plate energetically, and guarantee that the upper plate of plate energetically is to be positioned on the lower port of steel column and to be horizontal attitude, stretch out outside the lower port of steel column the lower part of plate energetically;
5), insert jack between upper plate and lower roof plate, jack rises, and with the whole verticality of adjusting steel column and the levelness of its lower port, after the adjustment, keeps energetically plate and to exert oneself plate motionless;
6), directly with the extension of described plate energetically and following steel column welding, described extension and last steel column of exerting oneself plate welded;
7), weld steel column and follow the craft port of steel column down.
The invention has the beneficial effects as follows: steel column butt joint structural system up and down of the present invention, utilize a plurality of stiffener external members to be used as auxiliary connector, before last steel column and following steel column butt joint are assembled, provide application of force platform to jack, come steel column is located synchronously, proofreaied and correct by jack, and upper and lower strength plate can effectively be strengthened the stability of steel column butt joint port, thereby improve the assembly unit height of steel column, improve the safety guarantee coefficient of steel column butt joint assembly unit and construction in later period, the stress deformation when effectively reducing welding is to the influence of the installation quality of steel column.The supporting disposable installing and fixing method that provides of the present invention can be finished the described construction of steel column butt joint structural system up and down fast, safely, in an orderly manner.The present invention can be widely used in the realm of building construction.
