Features of lampposts: types, sizes, installation

A lamppost is one of the types of lighting pole. The main characteristic is the trunk in the form of a single structure — racks. This distinguishes the pillar from the supports, which can be represented not only by a rack but also by a more complex structure, for example, a lattice (truss).

Street lampposts are made mainly of metal — steel of a certain grade, which is chosen depending on the climatic region. The barrel can be cylindrical, cone-shaped, or faceted. The main requirements for poles are given in GOST 32947–2014, which specifies the classification, technical

requirements, rules for marking, storage, and transportation.

Lamppost Dimensions

Lighting poles with a height of 6 m are installed on city streets. These are the most common models of poles since 6 m is the minimum required so that medium-duty freight vehicles can pass along the road. The maximum height of the poles is 12–13.5 m; in some cases, poles with a height of 22 m are made in an individual order.

The total length of the column is slightly more than the declared height since the structure has an underground part, which is buried in the ground and fixed by concreting. If, after installing the fixtures, it is found that the illumination is too high, they simply replace it with less powerful devices.

The diameter of a lamppost can be constant or variable along the length of the stem. The latter applies to round-conical supports, which gradually taper towards the upper end. This design of the column allows you to save steel and increase resistance to stress.

Decorative supports

Lampposts for parks and squares are no more than 3–6 m high. Most of these poles are of the floor lamp type. Depending on the installation location, there may be one or more ceiling lamps on the support. Installed are spherical and hemispherical. There are also lamps of reflected light, which eliminate the blinding effect on passers-by. Decorative supports are suitable for alleys, footpaths, and the private sector. Often such pillars are found near fountains, architectural structures, and public buildings.

Utility supports

Unlike decorative poles, utility poles have a simple design, since aesthetics are not so important to them. The main thing is to achieve optimal distribution of light at ground level. Depending on the required level of illumination, one or more lamps are installed on the pole. They are mounted on brackets mounted on the top of the pole. Brackets can be directed in one or different directions.

How far apart are the supports

An important parameter in the organization of street lighting is the . It is calculated taking into account that the light spots formed on the surface of the earth from lamps located on adjacent support intersect. This is important because it avoids the formation of dark areas. When calculating, they adhere to the ratio of the height of the support to the spacing of 1:7 with the classical arrangement of pillars opposite each other and 1:5 with a chess pattern.

Finally

Thus, street lighting lampposts are poles that can be seen on all streets of the city. These can be utilitarian or decorative designs. They are the most functional and easy to maintain, suitable for installation in any part of the city: on the roads, in the courtyards of residential buildings, and in parks and squares. Depending on the installation location, supports with a height of 3–12 m is used. The specific height is chosen to take into account the required level of illumination, which is determined separately for each object.
