What should I pay attention to when installing FRP bracket?

In various building facilities, FRP supports are suitable for laying cables with various cable sections, and are used to fix the supports of cables in power cable trenches and telecommunication cable trenches. The performance of FRP bracket stands out among many similar facilities. Glass fiber reinforced plastic bracket has many excellent properties. Next, Bian Xiao will give you a detailed introduction about the relevant knowledge of FRP bracket, including what is FRP bracket. I hope that after reading it, you will have a certain understanding of the FRP bracket.

1. What is a FRP bracket?

Glass fiber reinforced plastic cable bracket is a steel frame made of composite materials with synthetic resin as binder and glass fiber and its products as reinforcement. Suitable for laying cables with various cable sections, with good tensile and bending strength.

Second, the installation method of FRP bracket

Combined cable bracket

A set of brackets includes FRP columns, bracket arms, pins (bolts) and polymer fixing caps. The installation tools are common electric drills, drills and wrenches.

1, column installation: install an installation hole with an aperture of Ф12.5 on the positioning line on the back of the column. According to the installation construction drawing and the position of the column installation hole, fix the column on the wall with M 12 expansion bolt, and a gasket must be added between the bolt and the column to make the slot column as close to the wall as possible.

2. Cable: Drag the cable to the installation position of the cable bracket.

3. Bracket installation: according to the spacing requirements of the layers of brackets, assembly holes are reserved on the positioning lines on both sides of the column, with the aperture of Ф 8.5; Fix the bracket arm on the slot column with bolts. The bolt is moderately elastic, and a washer must be installed between the bolt and the column.

4. Cable positioning and fixing: put the cable on the bracket and tie it. When placing, try to place the heaviest cable at the root of the bracket.

Directly buried cable support

The directly buried cable bracket is a slender resin composite rod. The front is used to support cables. There are 2-3 grooves on the upper surface of the support section, and the cable is placed in the grooves, which has good stability. The tail of the bracket is an insertion section that can be inserted into the wall. The lower part of the insertion section is a flat plate, and the upper part is a cross-shaped reinforcement, which is exactly the same as the thickness of the red brick. It can be embedded in the wall when laying the cable trench wall, which is very convenient.

Bolt cable bracket

Bolt type composite cable bracket. Bolt-type cable bracket directly fixes the bracket by driving two expansion screws (12-14) into the cable trench wall, which is convenient to install and requires the cable trench wall to be flat, and can be used in cable trenches with different layers.

Three. Precautions for installation:

1, the installation should be economical and reasonable, with the shortest distance and safe operation, but the most important thing is to meet the requirements of engineering construction, laying and maintenance.

2, should have enough stiffness and strength, to provide reliable support for the cable.

3. After the cable is laid, the deflection of the trunking shall not be greater than 1/200 of the span of the support. When the span of the support is ≥6000mm, its deflection should not be greater than1150 of the span of the support.

4, try to install on buildings and structures (such as walls, columns, beams, floors, etc.). ).

5. When installed together with the process pipe rack, the bracket shall be arranged on one side of the pipe rack.

6. When all kinds of pipelines are erected in parallel, the clear distance should meet certain requirements.

The above is Bian Xiao's summary of the relevant knowledge about FRP stents, including what is FRP stents, how to install FRP stents, and what problems should be paid attention to when using FRP stents? The invention is suitable for laying cables with various cable sections, and is used for fixing cable support brackets in power cable trenches and telecommunication cable trenches. Here, Bian Xiao would like to remind everyone that when using and installing FRP brackets, if you encounter related technical problems, please ask technicians for help in time. I hope the above content is useful to you!
