| 摘要 |
<p>The invention relates to a method for producing a post-stressed mixed slab containing collaborating corrugated sheet metal, in the centre of which are placed inner plastic sheaths in the concrete part of the slab, in order to insert post-stressing tendons at a height which is approximately the same as that of the barycentre of the mixed section. The invention increases the distances between the supports of the slab, thereby allowing the application thereof to more complex structures relating to building construction, both civil and industrial.</p> |
