An intelligent roof drain system includes a roof drain surrounded by a drain plate. A water seepage detection module is disposed proximate the drain plate. The water seepage detection module includes water seepage detection sensors and circuitry and an antenna system to inductively receive power and communicate water seepage data. A roofing membrane is disposed over the water seepage detection module. A monitoring module that includes control circuitry, power supply circuitry, water level detection circuitry, communications interface circuitry, and an antenna system to inductively supply power to and communicate with the water seepage detection module is disposed proximate the water seepage detection module such that the antenna systems align. The intelligent roof drain system can detect water seepage under the roofing membrane and standing water proximate the roof drain and communicate such events to a gateway and/or building management system.

An apparatus for and method of diverting water is provided. The apparatus includes a contoured bottom configured to engage a roofing surface, a backwall extending from the contoured bottom and first and second sidewalls extending from the contoured bottom. The method involves using the apparatus to engage a roofing surface, receive a flow of water, direct the flow of water, and drain the flow of water through an opening.

A roof system is provided. The roof system includes a roof body capable of forming a flat roof or a corrugated roof, where the roof body is provided on a roof pillar; a gutter system is provided at a valley position of the corrugated roof or on the flat roof; a skylight system is further provided at a pitched roof or a ridge of the corrugated roof or on the flat roof; and a pressure relief adjustment component is provided on the skylight system. According to the roof system, a plurality of roof modules are assembled into the roof body. Two adjacent ones of the roof modules are fixed by a connecting plate and a self-locking component when assembled. A plurality of reinforcing points work cooperatively, so the roof system achieves a high utilization rate, and ensures the overall stability and bearing capacity of the roof.

A cover for a drain. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower portion with a large area extending outwardly at a small enough angle with respect to the horizontal to allow debris buildup thereon. An upper portion may be connected to the lower end and may be more vertically-oriented than the lower portion. Openings in the upper and lower portions allow for fluid drainage therethrough. Drainage occurs even with debris buildup around or on the cover.

A cover for a drain. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower flange or skirt portion with a large area and extending outwardly in an arcuate or polygonal configuration and having openings for fluid flow. The lower portion may be oriented at a positive, zero, or negative angle with respect to the horizontal. The lower portion may be wider than a drain body over which the cover is used. An upper portion may be connected to the lower portion and may be more vertically-oriented than the lower portion and having openings.

A cover apparatus (1), comprising cover plates (2) continuing in a position of use in a common plane and in at least one row, is formed in a mutual edge-side contact region (3) through overlapping and in a rainproof manner, such that edges (5) running parallel to each other and spaced apart on each cover plate (2) are designed differently (6), and the top side (7) of the cover plate (2), a continuing web (8) and a rain gutter (9) under said web (8) are arranged on a first edge (5), wherein said rain gutter belongs to the same first edge (5). If necessary, penetrating rain water (12) can be caught in the rain gutter (9) by overlapping edge-side webs (8) in the position of use.

A rooftop rainwater drainage assembly that is at least partially concealed from view from an exterior of a dwelling. In particular, the rooftop drainage assembly can include an opening spout secured to a roof deck region of a dwelling, and an elongated downspout having a first region disposed between an exterior wall and an interior wall of the dwelling and secured to the opening spout, thereby at least partially concealing the downspout from view from both the interior wall and exterior wall of the dwelling.

A cover for water flow inlet for rainwater drainage of roof and buildings is disclosed. The inlet cover comprises an outer formation forming a plurality of ridged fins to avoid the vortex formation of rainwater entrainment and to protect the cover from debris materials and a central plate member. The central plate member has a profiled lower surface. The plate member is of an inverted shape with a plurality of ridged formation or channels on the lower surface to further eliminate formation of air inducing and vortices, therefore promoting high volume laminar flow of water in the inlet pipe of the drainage system.

A passenger cabin for a means of transport is provided, which comprises an upper passenger deck and a lower passenger deck. The floor of the upper passenger deck comprises a lower and an upper region arranged therebeside, which are interconnected via a step or a ramp. There is an aisle in the lower region. The floor of the lower passenger deck likewise comprises a lower and an upper region arranged therebeside, between which there is a lowered aisle which is arranged so as to be laterally offset from the aisle of the upper passenger deck. The available surfaces of the upper and the lower passenger deck are mirror-symmetrically arranged. In this way, the space available can be used very effectively in order to accommodate more passengers.
