WATERPROOF DECORATIVE ARCH CEILING IN UNDERGROUND STRUCTURES Russian patent published in 2009 - IPC E21D11/38 

FIELD: construction.

SUBSTANCE: device consists of panels, supports and water intake chute. The panels have U-shaped flanged cross sections. The flanges and ribs of panels are different with regard to the required width and height along the corresponding sides of U-shaped cross section. The upper support to the bearing lining fastener assembly and lower panels to support fastener assembly are spatially distanced and implemented so that canopy panels and effective canopy hanger can be remotely adjusted to the bearing tunnel lining regardless canopy panels width and lining elements width dimensions. The upper fastener assembly is provided with supporting element for assembling pin, for example, pivot block, with one end being fixed to the bearing lining by means of fastening element, for example, bolt and/or threaded pin and/or anchor. The other end is coupled with the assembling pin, by means of, for example, a pair of nuts with spherical surface and beveled washers. The lower panel to support fastener assembly is made from the supporting element and clamping element for panels and installed on the assembling pin. The panels are installed and fastened to ensure the required architectural geometry of arch and overflow conditions in the lower panel fastener assembly for water penetrating through the lining. The position of the lower fastener assembly is adjusted by the upper fastener assembly. The invention provides for different structural implementation of the upper fastener assembly and specific features of U-shaped panel profiles and lower fastener assembly for the includes tunnel and horizontal tunnel.

EFFECT: possibility of spatial assembling pin position adjustment and installation of canopy panels in designed position regardless arch configuration inaccuracies in underground structure; more effective, reliable and simplified hanger for canopy to be attached to bearing lining notwithstanding canopy panel width and lining width ensuring conditions of penetrating through lining water.
