The frame comprises two uprights (1, 2) having a generally trapezoidal cross-sectional shape and upper and lower rails (3, 4). The upper rail may have a U-section and the lower rail constitutes a solid beam which is capable of fitting in the U- section of the upper rail of a subjacent frame and of being rendered rigid with the latter and with adjacent flooring slabs by the pouring of a binder such as a high-early-strength concrete or a concrete containing resin. The upper rail of the subjacent frame may define with the corresponding upright a tongue (21) which is capable of fitting in a groove (22) defined between the lower rail and the corresponding upright of the upper frame. Positioning of the frames is simplified and the structures of multi-storey buildings resulting from their assembly have an exceptionally high rigidity. <IMAGE> |
