<p>Intermediate beams are connected to supporting tubular beams via pile wall locks, to make up pile walling. A supporting beam has a half or a full intermediate beam welded to it directly, on two opposite sides. Each of these is connected to a further intermediate beam through its externally sited pipe wall lock. The welded intermediate beams may have a support unit likewise welded to the support beam, pref. in the form of a continuous support wall. The chamber bounded by the support wall and supporting beam may be sealed by a base plate at the bottom.</p> |
