1. Anchor fasteners
Anchor fasteners are like the "roots" of seismic supports. They are the key components that firmly connect seismic supports to the building structure. Common anchor bolts include chemical anchor bolts, mechanical anchor bolts, etc. Chemical anchor bolts fix screws in concrete through chemical agents and have high anchoring force and fatigue resistance. Mechanical anchor bolts achieve anchoring by utilizing the principle of mechanical locking keys. According to relevant construction experts, high-quality anchor fasteners can withstand huge tensile and shear forces, ensuring that seismic supports will not easily fall off during earthquakes. For instance, in some large commercial buildings, the use of high-quality chemical anchor bolts as anchor fasteners can closely connect the seismic supports with the main structure of the building, providing a solid foundation for the seismic performance of the entire building.
2. Reinforce the suspension rods
Reinforcing hangers can be regarded as the "spine" of seismic supports. They are mainly used to bear the vertical loads of equipment such as pipelines and cable trays and transfer them to the building structure. Reinforcing suspension rods are usually made of materials such as channel steel and round steel. Reinforced suspension rods of different specifications are suitable for equipment of different weights and sizes. Generally speaking, the larger the diameter and wall thickness of the hanger, the stronger its load-bearing capacity will be. In some industrial plants, due to the large number and heavy weight of pipelines, thicker reinforcing hangers need to be used to ensure the stability of seismic supports.
3. Anti-seismic connectors
Seismic connection parts are like the "joints" of seismic supports. They are used to connect and reinforce hangers, beams and other components, making the entire seismic support form a complete system. Common seismic connection parts include pipe clamps, seismic diagonal brace connection parts, etc. These connecting parts have good strength and toughness, and can effectively transmit and disperse seismic forces during earthquakes. For instance, pipe clamps can firmly fix pipes to seismic supports, preventing them from shaking and shifting during earthquakes. Seismic diagonal brace connectors can enhance the lateral stability of seismic supports.
4. Crossbeam
The crossbeam is the "shoulder" of the seismic support. It is mainly used to support equipment such as pipelines and cable trays, and transfer their horizontal loads to the reinforcing hangers and building structures. Beams are usually made of materials such as channel steel and I-beams. The length and cross-sectional dimensions of the crossbeam are selected according to actual needs. In some hospital buildings, due to the need to install a large number of medical equipment pipelines, longer and thicker beams are required to ensure the safe operation of the equipment.
