Drain and a building structure having a drain

A building structure defining a room, the structure comprising:

• a wall including a watertight covering, a floor and a floor drain arranged adjacent said wall, said floor being exposed to running water and also including a watertight covering, said floor being inclined towards said wall to enable said water to flow by gravity towards said wall and to be discharged through said floor drain;
• said floor drain including,
• a bottom part having at least one discharge opening;
• a front part with a first part integral with said bottom part and inclined to said bottom part at an angle of at least 30°;
• two side walls integral with said bottom part and said first part;
• and
• a back part integral with said bottom part;
• said bottom part, said first part, said side walls and said back part defining a receptacle for said running water;
• said front part including a flange part extending outwardly from said receptacle at an angle to the horizontal of less than 20°, said flange part being at least partially covered by a part of said watertight covering that covers said floor;
• and
• a grating covering said receptacle and having an upper surface;
• said back part extending vertically from said bottom part and up to a level above said upper surface of said grating, a face of said back part facing said bottom part being at least partially covered by a part of said watertight covering that covers said wall.

A method of constructing a building structure defining a room, said structure comprising a wall and a floor each including a watertight covering, said floor being exposed to running water, said building structure further comprising a floor drain located adjacent said wall, said floor drain including a bottom part having at least one discharge opening, a front part with a first part integral with said bottom part and extending at an angle to said bottom part of at least 30°, two side walls integral with said bottom part and said first part, and a back part integral with said bottom part, in which said bottom part, said first part, said side walls and said back part define a receptacle for said running water, said front part including a flange part extending outwardly from said receptacle and having an upper surface that extends at an angle to the horizontal of less than 20°, said flange part adapted to be at least partially covered by a part of said watertight covering that covers said floor, and a grating having an upper surface, said back part extending vertically from the bottom part, through and above the plane defined by said flange part, and above said upper surface of said grating, said back part being at least partially covered by a part of said watertight covering that covers said wall, said method comprising the steps of:

• securing said floor drain in a fixed position to the wall of said building structure or to said floor;
• and
• subsequently applying said watertight covering on said wall, on said floor, at least partially on a face of said back part facing said bottom part and at least partially on said upper surface of said flange part.

A floor drain for use adjacent to a wall in a floor of a wet area in a building structure, said floor being exposed to running water in use of said wet area, the wall and the floor including a watertight covering and said floor being inclined towards said wall to enable said water to flow by gravity towards said wall and to be discharged through said floor drain arranged adjacent said wall, said floor drain comprising:

• a bottom part having at least one discharge opening;
• a front part with a first part integral with said bottom part and extending at an angle to said bottom part of at least 30°;
• two side walls integral with said bottom part and said first part;
• and
• a back part integral with said bottom part, said bottom part, said first part, said side walls and said back part defining a receptacle for said running water;
• said front part including a flange part extending outwardly from said receptacle and extending at an angle to the horizontal of less than 20°, said flange part adapted to be at least partially covered by a part of said watertight covering that covers said floor;
• and
• a grating covering said receptacle and having an upper surface;
• said back part extending vertically from the bottom part, through and above a plane defined by said flange part and above said upper surface of said grating, said back part being at least partially covered by a part of said watertight covering that covers said wall;
• and
• said back part further including an intermediate part extending between said two side walls and defining a generally horizontal surface.

A floor drain comprising:

• a water receptacle defined by a bottom part, an inclined front part, side parts and a back part, said bottom part having a discharge opening;
• a flange part on said front part extending outwardly and generally horizontally from said receptacle;
• a grating covering said receptacle and having an upper surface;
• said back part extending vertically from said bottom part, through and above a plane defined by said flange part and above said grating upper surface;
• a watertight covering at least partially covering said flange part and said back part;
• and
• a trap connected to said discharge opening, said trap including a bowl, a first section with a funnel-shaped part and a second section with a bowl-shaped part, said first section extending at least partially within said second section, and said first and second sections being arranged at least partially within said bowl.
