Embodiment Construction

[0013] See figure 1 , the present invention a kind of T-shaped anchor bolt hole plugging method, it comprises the following steps:

[0014] Step 1, burying the anchor bolt sleeve 1, the upper surface of the sleeve is higher than the surface of the equipment foundation 2;

[0015] Step 2, when retesting the foundation, the upper surface of the anchor bolt sleeve needs to be cut horizontally and polished;

[0016] Step 3, making the sealing steel plate 3: Make a square steel plate with a thin steel plate, the side length of the sealing steel plate is 100mm larger than the diameter of the anchor bolt hole, and open a round hole in the center, the diameter of the round hole should be larger than the anchor bolt hole The diameter of the hole is 1mm larger;

[0017] Step 4, before the equipment 4 is installed in place, put the prepared sealing steel plate on the anchor bolt, and use silica gel 5 to seal the gap between the anchor bolt hole sealing plate and the anchor bolt;

[00...

Abstract

The invention relates to an installation method for a foundation bolt. A T-shaped foundation bolt hole plugging method comprises the steps that firstly, a foundation bolt sleeve is buried, and the upper surface of the sleeve is higher than an equipment foundation surface; secondly, during foundation retest, the upper surface of the foundation bolt sleeve is cut to be horizontal and polished; thirdly, a plugging steel plate is manufactured, wherein the square steel plate is manufactured by means of a thin steel plate, the side length of the plugging steel plate is 100mm greater than the diameter of a foundation bolt hole, a round hole is formed in the center of the plugging steel plate, and the diameter of the round hole is 1mm greater than that of the foundation bolt hole; fourthly, before equipment is installed, a foundation bolt is sleeved with the manufactured plugging steel plate, and a gap between the foundation bolt hole plugging steel plate and the foundation bolt is sealed though silica gel; fifthly, after the equipment is installed and adjustment and acceptance check are finished, the foundation bolt hole plugging steel plate and the foundation bolt sleeve are welded fixedly, and therefore the foundation bolt hole is plugged. The T-shaped foundation bolt hole plugging method is simple in operation, high in construction efficiency, little in investment of manpower and material resources, and little in environmental pollution.

Description

technical field [0001] The invention relates to the installation of large equipment, in particular to a method for installing anchor bolts. Background technique [0002] Due to the large and important equipment of metallurgical machinery such as rolling mills and coilers, the anchor bolts are usually T-shaped anchor bolts. T-shaped anchor bolts generally cannot be grouted, but should be protected in a sealed form. In the past, the dry sand asphalt method was usually used for the plugging of T-shaped anchor bolt holes. When the dry sand asphalt method is used to seal the anchor bolt holes, the upper surface of the sleeve of the anchor bolt holes must be basically level with the surface of the rolling mill foundation, which is conducive to the filling of dry sand and asphalt. This method is implemented after the equipment adjustment and acceptance, and before the second grouting. The method is to first pour dry sand into the anchor bolt sleeve and make it compact. When the...
