Definitions

• the invention relates to a tile-shaped building ele ⁇ ment with recesses for forming ducts for through-feed of lines and the like.
• Such a tile-shaped building element is known from WO 88/04713.
• the ducts obtained with the known tile are particular ⁇ ly suited for passage of flexible hoses for instance for hot and cold water supply or for central heating. They are also suitable for rigid lines such as for sewage and gas. If the sewage lines are received in the ducts facing the bearing floor, they will rest with their sleeves on the bearing floor. In that case the line has no support between the sleeves and can sag if no special provisions are made such as arranging separate support blocks.
• a drawback is that, in use for sewerage for instance, care must be taken that the lines running in the lower ducts and debouching in a collecting main of greater diameter are situated, for a good drainage, higher than the collecting main. Care must in any case be taken that the centre lines of the line and the collecting main lie at the same level.
• the invention has for its object to obviate the above stated drawbacks. This is achieved according to the invention in that between the top surface and the bottom surface of the tile at least one tube-like duct is arranged.
• Such a tube-like duct which is therefore located at an interval from the bearing concrete floor, is very suitable for receiving liquid lines.
• the collecting main placed at the head ends of the floor assembled from such tile-shaped build ⁇ ing elements can be supported by the bearing concrete floor.
• An additional advantage is that lines can be present at more height levels. In the manufacture of the tile-shaped building element moulds can be used such that tube-like portions are recessed in the middle of the tile during forming thereof.
• each building element consists of two sections, wherein each section has recesses on the upper side and underside and the placing of at least the recesses on one of the sides is selected such that when corresponding sections are placed one on another recesses lie in mutual register to form a tube-like duct.
• the tube-like ducts are accessible during construction for the placing of the lines.
• the second section is placed on a first section and the covering layer arranged.
• the elements have a tongue and a groove whereby placing the sections in register is facilitated.
• the building elements can be placed mutually staggered such that no vertical continuous joins are present.
• the intermediate walls can be partly broken away.
• One of the sections of the tile can furthermore be provided with intersecting groups of parallel recesses which debouch substantially in the middle portion of a standing side face of the tile-shaped element.
• At least the or each lower section of a tile-shaped building element accord ⁇ ing to the invention can be provided in each standing side face with a niche-like recess, wherein the space formed by the niche-like recesses of at least two abutting elements is filled by a support element for supporting the upper section of the tile.
• fastening means can for instance be clamps which pre- ferably extend or hook round upstanding portions of the section.
• tile-shaped building element wherein the ducts run only in one direction and mutually parallel provides advantages in a building with storey floors, on each of which storey floors is present an allotted zone for corridors located at a distance from the building frontage, wherein a main duct for lines and the like is placed in the corridor zone, an auxiliary duct for lines and the like is placed close to the building frontage and placed between the corridor zone and the building frontage are tile-shaped building elements, the ducts of which extend between the main duct and the auxiliary duct.
• Cables and lines can then be carried from the main duct into the floor formed from the tile-shaped building elements without the danger of cables or lines becoming obstructed by transverse ducts.
• lines leaving the main duct such as electricity, data and telephone lines and the like can run beneath the lower ducts in the floor formed by the tile-shaped building elements according to the invention to the auxiliary duct, and from distributor means in the auxiliary duct lines for data, electricity and telephone for instance can be guided through the upper ducts in the tile-shaped building elements to a desired location in the office space between the corridor zone and the building frontage.
• the auxiliary duct can for instance be covered by a removable plate so that access to the auxiliary duct can always be obtained.
• Lines for water supply and the outlet lines can moreover also be placed in the tube-like ducts.
