<p>A structural unit for, a transportable prefabricated room element used in the construction of buildings comprises a prefabricated floor panel and rigidly attached to one or each of two opposite ends of the panel, an upstanding, prefabricated, load-bearing end structure. There is a gap between the end structure and the adjacent end of the floor panel which is occupied by a set or hardened filling (e.g., mortar or metal) and the end structure is rigidly fixed to the panel by tie rods which extend within the latter into holes in the end structure and are anchored to the end structure. In the case of two end structures, at opposite ends of the floor panel, the tie rods extend through the panel and connect the two end structures together. The unit is made, preferably in accordance with U.S. Pat. No. 3,416,273, by effecting relative movements between the floor panel and end structure to enter the tie rods into the holes in the latter but leaving a gap between the end of the panel and the end structure, reducing the gap to its final dimensions, introducing the setting filling into the gap before or after the latter is reduced to its final dimensions, and anchoring the ends of the tie rods to the end structure.</p> |
