Various accessories of seismic brace play a vital role in the whole seismic system.
- Anchor bolt accessories
Rear Expanded Bottom Anchor Bolt: By drilling holes, expanding the bottom and installing anchor bolts on the concrete substrate, the mechanical locking key principle is utilised to provide strong anchoring force. It is suitable for all kinds of concrete structures, and can ensure that the anti-seismic bracket is firmly connected with the building structure under the effect of earthquake, preventing the bracket from falling off. Rear Expanded Bottom Anchor Bolt has the features of high bearing capacity, easy installation, etc. Its material is usually high-strength alloy steel with special anti-corrosion treatment, which can be adapted to different environmental conditions.
Chemical anchor bolts: The anchor bolts are bonded together with the concrete substrate through chemicals to form a strong connection. Chemical anchor bolts have the advantages of fast construction and little damage to the substrate. In the choice of chemical anchor bolt, need to pay attention to the quality and performance of the chemical agent to ensure that it can maintain a stable bond under the action of the earthquake.
II． connectors class accessories
Pipe clamps: used to fix various pipes, according to the diameter of the pipe and different materials, the specifications and types of pipe clamps are also different. Pipe clamps are usually made of metal materials with high strength and good corrosion resistance. Under the effect of earthquake, pipe clamps can effectively limit the displacement of the pipeline, preventing the pipeline from rupture or falling off.
Channel steel connectors: used to connect the channel steel of the seismic brace to make the brace form a whole. There are many types of channel steel connectors, including channel steel locks, channel steel nuts and so on. These connectors can ensure a firm and reliable connection between the channels and improve the overall stability of the seismic brace.
Hinge connectors: used to connect the hinge between the seismic brace and the building structure, so that the brace can produce a certain displacement under the action of the earthquake and absorb seismic energy. Hinge connectors are usually made of high-strength alloy steel, with good corrosion and wear resistance.
III, seismic diagonal strut class accessories
Seismic diagonal brace: it is an important part of seismic brace system, which increases the stability of the brace by diagonal support. Seismic diagonal brace is usually made of channel steel, round steel and other materials, with high strength and stiffness. Under the action of earthquake, the seismic diagonal brace can withstand large horizontal force and prevent the brace from deformation or collapse.
Diagonal brace connectors: used to connect the seismic diagonal brace with other parts of the seismic brace, to ensure that the role of the diagonal brace can be given full play. The types of diagonal brace connectors include diagonal brace nuts, diagonal brace locks, etc., whose materials and performance should be matched with the seismic diagonal brace.
- accessories
Gasket: used to increase the friction between the connectors to prevent loosening. The material of gasket is usually rubber, plastic, etc., with good elasticity and corrosion resistance.
Bolts: used to connect the parts of the seismic brace, the strength and specification of the bolts should be selected according to the actual situation. Under the action of earthquake, the bolts should be able to withstand large tensile force and shear force to ensure that the connection of the bracket is firm and reliable.
In a word, the various accessories of seismic brace cooperate with each other and together constitute a complete seismic system. When choosing and using the accessories of seismic brace, it is necessary to make comprehensive consideration according to the characteristics of building structure, the type and specification of pipeline, seismic defence requirements and other factors to ensure that the quality and performance of the accessories meet the requirements, so as to provide a strong guarantee for the seismic safety of the building.
