Background technology
When petrochemical plant is installed the big heavy steelframe of 400 tons/H diesel oil hydrogenation stove, the steelframe of boiler need be aligned the location with steel sole plate accurately, since the high 25.244M of this boiler steelframe, wide 13.388M, monolithic combined hanging calculated weight 47.730T is so the lifting process that aligns bothers very much.This boiler steelframe is supported on ground 12 bases by 12 steel columns, be embedded with the stone bolt of 6 M40 * 1200mm in each basis, be welded with the steel sole plate of δ=46mm on the bottom of steel column, have on the steel sole plate and the corresponding hole of stone bolt, be connected with steel sole plate on the steel column by stone bolt pre-buried in 12 bases, steel column is fixed on the basis.
Construction hoisting method in the past is, in the bottom of steel column the stiffener between steel sole plate and steel sole plate and the steel column is all welded in advance, when lifting, stone bolt pre-buried in hole on the steel sole plate and the basis is aimed at, allow the borehole jack on the steel sole plate drop on the basis on the stone bolt, and then fix with nut.
There is following problem in this method:
1, because the boiler steelframe is not only high but also wide also very heavy, so in the process of lifting, the hole on stone bolt and the steel sole plate is difficult to align, whole aligning all needs crane gear auxiliary in the process, increased the holding time of large lifting equipment, the One-Shift Costs height;
2, in hoisting process, be easy to hit stone bolt curved or the screw thread on the stone bolt is broken.
3, aligning after the steel column in place (as: the horizontal absolute altitude of steel column, longitudinal and transverse position, gradient) is very difficult, wastes time and energy, and also needs the crane gear auxiliary construction simultaneously.
In sum, prior art is not only backward in technique, operating expenses is high, influence programming, also damage stone bolt easily, take defectives such as large-scale loop wheel machine time length, poor reliability.
The utility model content
The purpose of this utility model is that a kind of conveniently large-scale steelframe fast hoisting aligns the steelframe understructure not to be had, and to speed up the work, reduces operating expenses, prevents to destroy stone bolt in the construction, improves the reliability of engineering.
The utility model is to constitute like this: comprise reinforced concrete foundation, be embedded with stone bolt in the reinforced concrete foundation, be with steel sole plate on the stone bolt, steel sole plate is provided with stiffened panel and stiffener.
Above-mentioned large-scale steelframe fast hoisting aligns in the steelframe understructure, and described steel sole plate, stiffened panel and stiffener weld with steel column respectively.
Aforesaid large-scale steelframe fast hoisting aligns in the steelframe understructure, and described steel sole plate is provided with the U-shaped hole, and stiffened panel is provided with through hole, and stone bolt runs through U-shaped hole and through hole, and the stone bolt top is rotary with nut.
Owing to adopted technique scheme, compared with prior art, operating principle of the present utility model is earlier the steel sole plate on the basis have been carried out accurate centering and had good positioning in advance before formal lifting, and on steel sole plate and the steel column of preparing to be connected, finish center line, so to make when in place it align the course of work convenient and swift formal, and can speed up the work greatly, reduce operating expenses, reduce the holding time of large-scale loop wheel machine, prevent to break stone bolt in the construction, improved the reliability in the process in place.
