Benches used in green areas can be two types: without backrest and with a backrest. Benches without support have horizontal seats, są mniej wygodne i ustawia się je na ogół tam, where the need for short rest is expected, np. on the destination roads (Especially on slopes), next to the stairs and in other similar places. Such benches are also positioned there, Where. A smoking method of sitting is undesirable, for example, for representative reasons. Benches with support are set primarily in places organized and adapted for rest.
Benches with backrest and benches without support can be portable, periodically attached to the ground or placed in a given place permanently. From concrete-wooden benches, the seat is often removed for the winter, leaving only the died base.
The design of the benches may be different, Most often, however, the seat and support are made of wooden elements attached to the base with a metal structure. The metal base can be made of steel divers, angles or censers, It can also be cast from cast iron. In wooden metal benches, you often need to embed special elements stiffening their structure to the forces parallel to the length of the bench.
Basics of solid benches, less often portable, It is made as prefabricated concrete, and wooden elements are associated with concrete connectors made of steel sections. The wood was not welcomed, however, to settle directly in concrete.
The design of the bench should be so conceived, so that it is not possible to stay water on wooden and metal surfaces for a long time. It is also necessary to avoid direct connection or contact of wood with concrete in horizontal planes due to the persistence of moisture in such places.
Wooden parts and metal benches should be protected against the destructive effects of weather conditions. Wooden parts are saturated with fungicides for this purpose and at least twice painted with appropriate paints. Metal parts are protected against corrosion with generally known methods, of which the best is to cover them with a layer of zinc (galvanizing).
