Hall buildings or halls are usually single-storey buildings, whose load-bearing structures make it possible to obtain spacious interiors. The shape of the hall building's body depends on its purpose, method of use and applied construction and material solutions.
Depending on the nature of the buildings, there are halls with one-story pavilion buildings and halls with uniform one-story buildings. (under one roof) - blocked. Natural side lighting is used in the pavilion halls, while in block halls there is side and overhead lighting.
The load-bearing structure of the halls consists mainly of columns set on the foundations and a covering. In many solutions, the hall cover is based on the walls, or on poles and walls. The most important structure of the halls are the covers. The span of the hall covers is different and depends on the way the hall is used. Single-storey halls, sports, for exhibition purposes, congregations or some industries requiring large columnless rooms have coverings with a span of up to 100 m.
Depending on the method of development and the shape of the internal space, there are single-bay and multi-bay halls with the same height of all naves or with different heights. The following factors influence the spatial configuration of industrial halls: type of production, dimensions of manufactured elements, the course of the technological process, type of internal transport, lighting and other requirements related to the type of production.
The course of the technological process may be unidirectional or multidirectional. In a unidirectional course, the production processes usually proceed along the aisles. Therefore, larger spans of naves and any column spacing are used (supports) in the directions of their length (these spacings may be smaller or larger). In the multidirectional course, there is usually a close connection of technological processes between individual aisles. For these reasons, greater column spacing in the longitudinal direction of the aisles should be used.
