Embodiment Construction

[0028] In order to make the present invention more clearly understood, the technical solution thereof will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] As shown in Figure 1, the grouting backing plate construction method of the present invention comprises the following steps:

[0030] (1) Utilize the principle of three points to determine a plane, weld the thin plate 3 fixed to it on the 3 points on the periphery of the backing plate 7 used, and set the round hole for installation on the thin plate 3, the thin plate 3 The thickness is 2~3mm;

[0031] (2) dig out the grouting pit 6 at the concrete foundation 5 positions where the pad iron 7 needs to be set, and expose the embedding bars 8 in the 5 positions of the concrete foundation, the length and width of the grouting pit 6 should be greater than the pad The length and width of the iron 7 are 80-120 mm, and the depth of the grouting pit 6 drilled into the foundation su...

Abstract

The invention discloses a grouting shim plate construction method. The method comprises the following steps of: arranging a sheet which is fixed with a shim plate at three points on the periphery of the used shim plate and making a circular hole in the sheet; chiselling grouting pits at a position of a concrete foundation provided with a shim iron, and clearing away impurities in the pits; vertically arranging three screw bolts in each grouting pit and arranging regulating nuts on the screw bolts; arranging the shim plate on the screw bolts and regulating the elevation and the horizontality of the upper plane of the shim plate through the regulating nuts; arranging grouting moulds on the peripheries of the grouting pits and continuously and unremittingly pouring Gordon growth model (GGM) high-strength shrinkage-free grout from one side of each grouting mould; after initial set of the grouting material, smoothing and maintaining the surface of a grouting layer which is exposed in the air, and after final set, watering for maintaining the grouting layer; and the like. The construction method has the advantages that: the construction process is simple; the strength is easily ensured; and manpower, materials and time are saved.

Description

technical field [0001] The invention relates to a method for construction of backing plates for equipment installation. Background technique [0002] In the installation process of cold rolling equipment, the backing plate construction of rolling mill floor, uncoiler and coiler is one of the key processes. The existing construction method mainly utilizes cement, gravel, sand to mix water to stir the recoil slurry. There are following deficiencies in this method: [0003] (1) The mixing ratio is strict and difficult to operate. [0004] (2) The construction procedure is complicated, and the strength is not easy to guarantee. [0005] (3) Increase human resources and construction time. [0006] (4) Cannot meet the installation technical requirements of foreign experts. Contents of the invention [0007] The problem to be solved by the present invention is to overcome the deficiencies of the prior art, and to provide a backing plate construction method with grouting meth...
