China AB type hinge connector Manufacturers, Factory

Here we introduce AB hinge link. AB hinge link is a matching combination of A-type hinge and B-type hinge. It is a key adjustable connector of seismic support and hanger. It is manufactured according to GB/T 37267 and GB 50981 standards. It is used for the single axis rotation connection between diagonal brace and C-type steel/structural substrate. It can flexibly adjust the installation angle (commonly 45 Â° slant support) to absorb horizontal displacement and vibration during earthquake.

Seismic Function

Allows the support and hanger to rotate at a small angle during earthquakes, avoiding structural rigidity damage.

Strong Universality

Suitable for various specifications of seismic resistant C-shaped steel (such as 41, 41 × 21, 52, 62 series).

Applicable Scenarios

Building Electromechanical Systems Lateral and longitudinal seismic supports and hangers for water supply and drainage, HVAC, fire protection, and electrical cable trays.

Pipe Gallery Engineering Hinged connection of pipeline supports in the comprehensive pipe gallery.

Seismic Reinforcement & Renovation Seismic reinforcement and renovation projects for steel structure factories and large public buildings.

Frequently Asked Questions

Does the installation of these seismic supports require welding?

No, welding is not required. The system is designed for quick and easy fixation using bolts and toothed nuts, allowing for convenient on-site fine-tuning.

Which sizes of C-shaped steel are compatible with this product?

It features strong universality and is fully compatible with various C-shaped steel specifications, including the 41, 41 × 21, 52, and 62 series.

How does the adjustable angle design benefit installation?

The bracket can rotate freely around the pin axis. This makes it highly flexible and suitable for any oblique installation angle, whether for lateral or longitudinal seismic supports.

How does the seismic function protect the structure during an earthquake?

It allows the support and hanger to rotate at a small angle during an earthquake. This minor rotation helps buffer the impact and prevents severe damage caused by structural rigidity.

Can this product be used for fire protection systems?

Yes, it is highly applicable to building electromechanical systems, including fire protection, water supply/drainage, HVAC, and electrical cable trays.
