Abstract (en)
[origin: JPH01146052A] PURPOSE: To simplify structure and to firmly and rapidly build up a staircase of optional form by connecting only plural kinds of completely finished standardized parts to constitute the staircase. CONSTITUTION: Handrail parts 2 connecting each connecting frame 1 are arranged at the upper ends of the required number of U-shaped connecting frames 1, and staircase steps 3 of specified shape are mounted and fixed into specified positions near the lower ends of the connecting frames 1 through clamp fittings. These elements are standardized, mass-produceable and economically manufactured and fitted to obtain an outdoor staircase usable without special structure substantially for an optional flight of stairs.

Selbsttragende Elementtreppe, bestehend aus U-förmig gebogenen Stahlrohrbügeln (1), die quer zum Treppenlauf stehen. Diese Bügel werden an ihren oberen offenen Enden durch Handlaufteile (2) verbunden, die ebenso aus gebogenem Stahlrohr mit an einer Seite angeschweißter Verbindungsmuffe bestehen. In ihrem unteren Bereich werden die Rohrbügel durch die Trittstufen (3) verbunden, die an ihren vier Ecken Rohrschellen-Klemmverbindungen besitzen. Zwei verschiedene Trittstufenformen ermöglichen den Bau jedes gewünschten Treppenlaufes.
