The invention relates to building and can be used for assembled large-span spatial floors of buildings. Spatial floor includes metal module elements, the upper and the lower ledges, reinforced-concrete slabs. Module elements are arranged as flat trusses with length “by span” and are installed at angle 45° to vertical axis of floor, and after connection of ledges of neighboring trusses those form spatial structure with angle between module elements 90°, at that the ledges of trusses are made of single angle elements placed at angle 45° to vertical axis of the truss. The upper ledges are cross-like links of shift and lodgement for assembled reinforced-concrete slabs or reinforcing meshes. Economy of materials and high rate of mounting is provided. |
