<p>A prefabricated roof truss is provided especially for covering car parks and is appropriate, namely, for covering either at least one parking space or a number of spaces required at any time in a set of arranged parking spaces. The roof truss enables an effective protection of a vehicle parked at any time against weather effects allowing at the same time as simple and safe accessibility to the parking space with the vehicle as possible and also a possibility of entering or leaving the vehicle respectively. The roof truss enables, in particular, a quick and cost-effective erection on the area of already existing parking surfaces in the open air. The roof truss consists of console beams (1) required at any time, over which the roof (3) is mounted, each of the beams being fixed to a respective foundation (2) which is built at least mostly in a subsoil available at any time. Each particular beam (1) is designed as a prefabricated element fixable to the foundation (2) which is a prefabricated reinforced concrete product too and which consists of a markedly widened lower overlying part (21), prolonged in the direction of the beam (1), as well as of a narrowed and smoothly rounded fixing part (22) which is extending at least partly above the level (100) of each particular subsoil.</p> |
