What details should be paid attention to during the installation process of seismic brackets

1、 Preparation before installation

Design planning:
Based on the layout of the building structure and electromechanical system, professional designers design seismic supports and determine parameters such as the type, location, and spacing of the supports.
The design should be based on relevant seismic design specifications, such as the "Code for Seismic Design of Building Mechanical and Electrical Engineering" GB 50981-2014, etc.

Material procurement:
Purchase seismic support components of appropriate specifications and quality according to design requirements, including channel steel, connectors, pipe clamps, anchor bolts, etc.
Ensure that the materials comply with national standards and design load-bearing capacity requirements.

Inspection and cleaning:
Conduct a comprehensive and meticulous inspection of the bracket to ensure its superior quality and compliance with regulatory requirements.

Clean the installation area to ensure there are no obstacles or debris, in order to efficiently and accurately complete the installation work.

2、 Installation process

Measurement and positioning:
Accurately mark the installation position of the bracket on the building structure, considering factors such as the direction and slope of the pipeline.
Use measuring tools for precise measurement to ensure the accuracy of the bracket position.

Drilling and installation of anchor bolts:
Use appropriate tools to drill holes at the marked locations, ensuring that the hole diameter and depth meet the requirements of the anchor bolt.
When installing anchor bolts, it should be ensured that the anchor bolts have sufficient anchoring strength and meet the load requirements of the building structure type and seismic support.

Installation bracket body:
Assemble the main components of the bracket, such as channel steel, through connectors and securely connect them with anchor bolts.
During the installation process, it is necessary to ensure that the verticality and flatness of the bracket meet the requirements to avoid deviation.

Install pipe clamps or bridge connectors:
For pipelines, install the pipe clamp on the bracket and secure the pipeline to ensure a tight and reliable connection between the pipeline and the bracket.
For electrical cable trays, use corresponding cable tray connectors to connect the trays to seismic supports, paying attention to fixing them firmly and not damaging the trays.

3、 Installation details and precautions

Avoid forced squeezing:
It is prohibited to force the seismic bracket to compress other pipelines or change the angle of the vertical hanger during installation, in order to avoid endangering the application function of other pipelines and the seismic grade effect of the seismic bracket.

Tightening of connectors:
When installing seismic supports, the external threads of the hanger should be complete, and the connection between the anchor bolts, hex nuts, and hanger should be firm and stable.

Consider thermal expansion and contraction:
The seismic support limit of the insulated pipeline should be designed according to the size of the pipeline after insulation, and should not limit the displacement caused by thermal expansion and contraction of the pipeline.
When using a sliding bracket, it is necessary to move the installation position appropriately to ensure that the sliding bracket of the pipeline remains on the steel support after thermal elongation.

Preventing corrosion:
After cutting materials such as channel steel, metal zinc spray should be sprayed on the cut to prevent corrosion of the cut.

Safe operation:
Workers should check in advance whether there are any issues that may affect the safe operation of seismic supports during work.
When unsafe situations and signs are found during operation, the operation should be stopped immediately for inspection, and normal operation can only be resumed after resolution.
When performing operations such as prying, pulling, pushing, and pulling, it is important to adopt the correct posture and stand firmly to avoid losing balance or throwing things out when applying too much force.

Keep the shelf surface clean:
During the installation of seismic supports, clean up any materials that fall onto the frame surface at any time, keep the frame surface neat and clean, and do not place materials and tools randomly to avoid affecting the safety of one's own operation and causing injury from falling objects.

4、 Quality inspection and adjustment

Check installation quality:
Check whether the installation position of the bracket is accurate, whether the connection is firm, and whether there is any looseness.
Check whether the pipe clamps or bridge connectors are reliably fixed to the pipeline and bridge, and whether they affect the normal expansion and contraction of the pipeline or the laying of cables inside the bridge.

Adjustment and acceptance:
Adjust the deviations that occur during the installation process to ensure that the entire seismic support system meets the design and specification requirements.
A comprehensive inspection should be conducted during acceptance to confirm that the seismic support is installed firmly, stably, and without any looseness.
