Embodiment Construction

[0020] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] The invention provides a quick processing method for a rolling mill foundation, comprising the following steps:

[0022] S1. Remove the loose or broken anchor bolts and the surrounding concrete to form a gap, and make the remaining steel bars at the upper and lower ends of the gap. Refer to image 3 ;

[0023] S2, such as figure 1 As shown, install the bracket 1 into the notch to support the upper and lower ends of the notch;

[0024] S3, such as image 3 As shown, the steel bars at the upper and lower ends of the gap are connected and fixed with the connecting piece 5, and the vertical steel bars are connected through the hoop 6. Both the connectin...

Abstract

The invention relates to a rolling mill foundation rapid treatment method. The method comprises the following steps that a loosened or broken foundation bolt and concrete around the foundation bolt are removed to form a notch, and remaining steel bars are arranged at the upper end and the lower end of the notch; a bracket is mounted into the notch for supporting the upper and lower ends of the notch; the steel bars at the upper end and the lower end of the notch are connected and fixed through connecting pieces, and vertical steel bars are connected through hoops; an intact foundation bolt isfixed through a steel plate; the steel plate is installed in the notch and fixed to the steel bars in the notch; concrete is poured into the notch, a gap is reserved between the concrete and the upperend of the notch, and the steel plate is fixed to the outer surface of a foundation; and a reinforced non-telescopic grouting material is poured between newly poured concrete and the upper end of thenotch, and the bracket is dismounted. The bracket supports the upper and lower ends of the notch to avoid foundation collapse; the hoops are welded with the vertical steel bars in the notch, so thatthe strength of the steel bars in the notch is improved; and only local crushing construction is needed, the construction period is shortened, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of rolling mills, in particular to a quick processing method for rolling mill foundations. Background technique [0002] In major metallurgical enterprises, the rolling mill is the core equipment of the major steel rolling workshops. The working status of the rolling mill directly affects whether the main line can be produced normally, and the quality of the rolling mill foundation is directly related to the working status of the rolling mill. The upper end of the rolling mill foundation is equipped with a motor and a reducer installed through anchor bolts, and the rolling mill is fixed on the side of the foundation through anchor bolts. The crushing, removal and re-casting of the concrete foundation of the rolling mill not only requires a long construction period but also costs a lot. Contents of the invention [0003] The technical problem to be solved by the invention is: to solve the technical problem...
