Seismic brace is a kind of component or device that restricts the displacement of the attached mechanical and electrical engineering facilities, controls the vibration of the facilities, and transmits the loads to the load-bearing structure. Seismic brace should give reliable protection to the building mechanical and electrical engineering facilities in an earthquake, and withstand seismic action from any horizontal direction;
Seismic brace should be calculated according to the load it is subjected to; all the components composing the seismic brace should be finished components, and the components connecting the fasteners should be easy to install; the seismic brace limit of the insulated pipeline should be designed in accordance with the dimensions of the insulated pipeline and should not limit the displacement caused by the thermal expansion and contraction of the pipeline. Displacement generated by thermal expansion and cold contraction of the pipe should not be restricted.
According to the sample drawing of seismic brace we can see that the seismic brace is actually a complete system assembled by different parts, and its main components can be divided into the following parts:
1. C-channel steel, screw and screw joints
The combination of C-channel steel and screw can play the role of load-bearing. the rolled edge of C-channel steel is serrated, and there are bar-shaped mounting holes on the back, which can be matched with other seismic fittings arbitrarily.
2. Seismic hinge joints (Type A/B)
Used for the connection between seismic rod and structure or portal bracket and structure, the installation angle can be flexibly adjusted according to the site conditions and design requirements.
3.Seismic pipe clamps (U-type, O-type, ohmic pipe clamps)
U-shaped pipe clamps, O-shaped pipe clamps, ohm pipe clamps and rubber mats used in conjunction can play a role in insulating shock absorption and noise resistance.
4.Other anti-vibration fittings
Plastic wing nuts (channel steel latch), reinforcing bars, hexagonal bolts, beam clamps (tooth pressure plate), buckle pads, etc.
Seismic stent equipment from the metal (galvanized, hot-rolled) coil strip at room temperature through groups of gradient rolls cold bending into a cold-formed thin-walled section shape.
PV Support Bracket Roll Forming Machine process: process: automatic two-in-one uncoiling and leveling machine (tape) → automatic servo chasing punching (high-speed punching) → high-precision high-speed molding equipment (roll molding) → automatic servo chasing shear (cut off) → bearer frame (products) → chasing chasing punching chasing Shear computer control system, instead of molding and then punching process, labor saving, high efficiency, product consistency is good!
Seismic stent equipment commonly used specifications are 41 * 21 41 * 41, 41 * 52, 41 * 62, 41 * 82 seismic stent, raw materials to hot-dip galvanized, hot-rolled, zinc aluminum magnesium material-based
