There is not escalator truss of support

The utility model relates to a there is not escalator truss of support, including interior truss (1), install outside in the truss interior truss (1), outer truss is by upper chord (2), well chord member (3), lower chord (4), tip montant (6), first horizontal pole (7) and second horizontal pole (12) welding constitutes, set up between upper chord (2) and lower chord (4) tip down tube (8), down tube (9), middle part down tube (10) and middle part montant (11) welding form, wholly be upper and lower bilayer structure, wherein set up between interior truss (1) lower surface and the first horizontal pole of outer truss (7) first lip block (5), set up between 1 side surface of truss and outer truss top chord (2) simultaneously second lip block (13). The utility model discloses vertical high increase reduces outer truss amount of deflection, improves staircase stability, because interior truss 1 and outer truss mutual independence can on -the -spotly be installed. 本实用新型涉及种无支撑自动扶梯桁架，包括内桁架（1），内桁架（1）安装在外桁架中，所述外桁架由上弦杆（
