When it comes to anchor bolts, I believe many people should have learned about undercut mechanical anchor bolts and inverted cone anchor bolts.        As important anchoring connectors, they are widely used in building reinforcement projects.        However, many friends are still not very clear about the differences between the two, so they don't know how to make corresponding choices.        Today, let me take you to understand in detail the differences and distinctions between them, which will help us choose the anchor bolts suitable for us.

Detailed introduction and analysis for everyone:

I.   Appearance difference

in terms of appearance, the inverted cone anchor bolt is also known as a shaped anchor bolt or a special inverted cone adhesive anchor bolt.        It is composed of a screw, a flat washer, and a nut.

The undercut mechanical anchor bolt is also known as a self-undercutting mechanical anchor bolt.        It is composed of a screw, a sleeve, a washer, a shrapnel, and a hexagonal nut.

II.        Construction method and anchoring principle

The inverted cone anchor bolt uses chemical bonding to complete anchoring.        Generally, a special injection-type rebar planting adhesive is used to complete anchoring.

The undercut mechanical anchor bolt uses mechanical locking keys and the friction with concrete or other objects to complete fixation.        It is a pure metal anchor bolt product and does not need to rely on any epoxy medium to achieve its anchoring effect.

III.        Anchoring performance

According to the construction methods of the two, it can be seen that the inverted cone anchor bolt uses chemical adhesive for anchoring, so its stability largely depends on the performance of the chemical adhesive.        Choosing a high-quality chemical adhesive becomes very important.        Shibang injection-type rebar planting adhesive meets the 50-year design service life standard.

The undercut mechanical anchor bolt uses metal materials, which can help maintain the fastening force for a long time.

IV. High and low temperature resistance and weldability

For welding and high and low temperature resistance, because the inverted cone anchor bolt uses chemical adhesive, and the adhesive used in ordinary types of inverted cone anchor bolts on the market has a relatively low melting point and is not easy to weld.        However, Shibang inverted cone anchor bolt has overcome this problem.        The inverted cone anchor bolt is resistant to high and low temperatures and can be welded.

Inverted cone anchor bolt & Under-cut mechanical anchor bolt

The undercut mechanical anchor bolt is a pure metal anchor bolt product and does not need to rely on any epoxy medium.        It has high temperature resistance and can be welded.        The working principle is safe and reliable.

V. Construction period

For the construction period, because the inverted cone anchor bolt is used in conjunction with injection-type rebar planting adhesive, it requires a curing time.        Especially when constructing in a low-temperature environment in winter, the curing time will be longer, which will cause an extension of the construction period.

The undercut mechanical anchor bolt can be installed and used immediately without waiting.        The construction is independent of the temperature environment, so the construction period will be much faster.

SummaryTwo types of anchor bolts

The above are the relevant differences between inverted cone anchor bolts and undercut mechanical anchor bolts introduced for everyone.        I hope it will be of some help to everyone!        In summary, inverted cone anchor bolts and undercut mechanical anchor bolts have great differences in appearance, construction anchoring methods, construction period, high temperature resistance and welding and other performances.

In practical applications, the appropriate anchor bolt type should be selected according to specific engineering requirements and usage conditions to ensure the quality and safety of the project.
