<p>1. Building skeleton composed of prefabricated parts, comprising a plurality of elements (21) in the form of slabs of reinforced concrete like floor or roof elements, said elements being disposed one above the other, said elements being joined by support columns (33, 34) which are provided with a steel cover plate (31, 35) at their ends, bars (32a, b and 36a, b) being anchored in the columns and projecting axially outwardly at each end of the support columns (33, 34) and being received into tubular sections (20, 24) which are provided at the corners of the elements (21), the ratio of the smallest interior distance of the tubular sections (20, 24) to the diameter of the bars (32a, b and 36a, b) being comprised between 3:2 and 5:2, while the projecting bars (32a, b and 36a, b) are placed in such manner that in the mounted state a corner of an element (21) covers about a quadrant of the head of a column (33, 34), while the tubular sections (20, 24) extend at least as far as the upper and lower faces of the elements (21), characterized in that the tubular sections (20, 24) provided at the corners of the elements (21) are positioned between the cover plates (31, 35) which present holes for the passage of the projecting bars (32a, b and 36a, b) while the said tubular sections (20, 24) transmit the vertical forces, the said tubular sections (20, 24) being constituted by a first angle iron (20), which forms the corner and does not pass beyond the extensions of the edges (22, 23) of the element (21) and by a second angle iron (24) which is welded to the first angle iron at the interior thereof so as to form a tubular opening, whilst pretensioned bars (27, 28) which reinforce the edges (22, 23) of the elements (21) are fixed to the flanges of the first angle iron (20) by the aid of fixation elements with nuts (29) and the hollow spaces formed between and in the tubular sections (20, 24) are filled at least partially with a hardenable mass (50).</p> |
