Installation Method Of Anchor Bolts And Installation Precautions

Anchor bolt suppliers will bring you the common rules and installation procedure of anchor bolts, such as the installation method of anchor bolts, the precautions for the use of anchor bolts, and the common rules, hoping to help you. And the supplier hopes that everyone should pay attention to safety when installing anchor bolts.

1. Installation method of anchor bolts

1)The anchor bolts are generally buried in pre-buried and reserved holes for secondary grouting. Both methods can bury anchor bolts in concrete.

2)The method of directly burying anchor bolts is suitable for the construction of large-scale machinery and equipment such as towers with large vibrations, tall containers, and spherical tanks.

3)When the anchor bolts are directly buried, the foundation edge dimension a≥100mm from the centerline of the anchor bolts. When the size is not satisfied, the installer must make adjustments according to relevant regulations to strengthen the degree of foundation fixation.

4)Put the anchor bolts into the reserved holes and then grout and fix them. This method is suitable for stationary equipment such as horizontal vessels, heat exchangers, small vertical vessels, and machines and pumps with less vibration. Its characteristic is that it is convenient to adjust, easy to locate the size of the anchor bolts, and does not need to use positioning templates.

2. Precautions for the installation of anchor bolts

The size of the reserved holes for anchor bolts must meet the requirements of civil construction and equipment installation.

1)The minimum size of the reserved hole is 100×100mm, the size of the bolt hook from the hole wall should be greater than or equal to 20mm, and the size of the hole wall from the foundation edge should be greater than or equal to 100mm. When the size cannot reach 100mm, the installer can use the pre-embedded method Or strengthen the foundation reinforcement.

2)The distance between the bolt hook of the anchor bolt and the bottom of the hole is about 80mm, and the depth of the hole = the depth of anchor bolt embedding + the distance between the bolt hook and the bottom of the hole.

3)If the equipment is installed on a concrete beam, then the anchor bolts are generally pre-embedded. If the equipment foundation has special requirements, professional installers can also pre-embed the casing on the concrete beam.

4)The size of the embedded casing should ensure that the gap between the anchor bolt and the casing is at least 10 mm so that the position of the bolt can be adjusted during the installation of the equipment for sand filling and compaction steps.

5)It should be noted that when installing the anchor bolts, the bolts need to have the proper length, good cushioning performance, strong stability, excellent quality performance, and easy replacement.

6)For equipment installed on steel beams, the specification and size design of bolts, nuts, and gaskets should be selected by professionals in installation engineering. When installing the foundation bolts, ensure that they penetrate the upper and lower edges of the foundation steel.
