Methods of installation of concrete pillars lighting

Outdoor lighting is necessary for normalurban life. The first street lights ensure safety, but also can be used to decorate parks and gardens. When installing street lighting important point is the choice of lamp poles. The most popular are the reinforced concrete and concrete lighting poles, due to its durability and reasonable price.

lighting poles

A principal lighting provides good visibility on the roads at night

Classification light poles

1. Materials:

  • reinforced concrete - can withstand heavy loads and sudden changes in temperature;
  • Concrete - durable, but are unattractive appearance;
  • metal - robust and aesthetically pleasing;
  • fiberglass - lighter, more weather-resistant than metal, available in various colors;
  • Wood - subject to more rapid decay, break down in strong winds.
Metal outer support amenable galvanizing - a long time protects them from corrosion process

2. By type of construction - may be tubular, multi-faceted, conical or lattice.

3. differ on the purpose of use:

  • street;
  • Trunk;
  • decorative.

Features reinforced concrete structures

Reinforced concrete lighting columns are hollow inside, butfor extra strength reinforced metal reinforcement. As the filler used crushed granite, which has a high resistance to frost.

It is important that the concrete does not corrode andIt is very resistant to collapse. Such support at least aesthetically unattractive, but reliable and can last up to 50 years. They are not destroyed by temperature changes from -55 to +50 degrees Celsius.

The benefits may also include fire resistance and easy maintenance. And thanks to the reinforcement can withstand load, at times in excess of those that survive the concrete lighting poles.

Moving and installation of lighting poles is performed using special equipment.

It is important to know that the reinforced concrete structure capable of causing great harm in the event of an emergency. The weight of such supports much more than metal or wood.

The advantage of reinforced concrete light poles is resistant to adverse environmental influences

Installation of outdoor lighting poles

Installation of lighting columns - this is an important stage of building works at the complex design and installation of outdoor lighting.

In order to do this properly, you must:

  • to develop a scheme of the lighting network;
  • spend the markup on the ground;
  • dig trenches for cables;
  • drilled out of the pit;
  • prepare the foundations;
  • mount the poles;
  • make installation of electrical wiring.

The distance between the light poles should be calculated in accordance with the planned load and capacity.

When developing the scheme, you immediately found the optimal location of lamps and their number. It is important to choose the right way to start and disconnect from the network.

Also depending on the intended use of the lighting design, lighting column height is selected.

concreting method can be applied tostrengthening the pillars of reinforced concrete and metal. To do this, first make drilling soil, taking into account pre-marking. Given the height and thickness of the post, the hole depth is determined. This work is carried out with special equipment or telescopic excavation drills that are placed on a car platform.

concreting method is simple and reliable

The hole diameter must be greater than the diameterPost 20 cm. If the soil is very soft, the pit lay the sand and granite rubble, about 15 cm. And only after that establish post. In order for it to be vertically use special temporary spacers. The remaining void is filled with concrete up to ground level.

For higher lamp poles usedflange fixing method. It should be ready to use a monolithic block of concrete with a mortgage from the anchor pins, to which is attached a flange. The unit is lowered into the pit with a pillow of sand and gravel, thoroughly compacted soil around the block. Flange nuts must be secured.

Installation is best done with the help of special equipment

It is important to remember that the installation of lighting columns,especially work with the wiring requires specific knowledge and use of special equipment and technology. Therefore it is better not to take yourself for this work, and trust professionals in this area.
