Definitions

  • the invention relates to a floor slab, which is intended for forming a flooring deck, and which floor slab includes cast concrete and building service systems.
  • the invention also relates to a method for forming a flooring deck and a building formed of precast floor slabs.
  • a flooring deck is used in buildings of two or more floors, in which the flooring deck is the ceiling of the lower floor and the floor of the upper floor. It is known to start building the flooring deck using hollow-core slabs, the hollow cores of which can be used, for example, for installing electrical cabling. On top of the hollow-core slab comes a surface screed and the chosen floor covering. Electrical heating can also be installed in the surface screed. In the lower floor, a so-called suspended ceiling is used, which is attached to the hollow-core slabs. Ventilation and electrical installation, for example, are installed in the air space remaining between the ceiling and the hollow-core slab. As such, building using hollow-core slabs is rapid and reasonably economical. Heating, plumbing, ventilation and electrical installations are, however, difficult despite that hollow cores.
  • the inserts make the floor slab lighter than a mass concrete slab.
  • the inserts are omitted and drainpipes, electrical conduits, and heating pipes are placed inside the floor slab during manufacture.
  • at least some of the building service systems are factory-installed.
  • a separate surface screed is avoided, so that the flooring deck takes up less of the room height than previously.
  • the sound insulation of a concrete floor slab is poor.
  • a floor slab is laborious to manufacture and the finished floor slab is heavy despite the inserts. This limits the span, even if prestressed reinforcement is used.
  • building service systems can only be installed in a floor slab to a limited extent.
  • the invention is intended to create a new type of floor slab, according to claim 1, which is cheap to manufacture and in which building service systems can be fitted, and which is lower and lighter than previously, but which has a greater load-bearing capacity.
  • the intention is to create a new type of method for forming a flooring deck, by which at the same time a significant number of the building service systems installations can be made.
  • the invention is intended to create a new type of building formed of floor slabs, in which the building service systems can be arranged more easily and freely than before.
  • the floor slab according to the invention there is a new and surprising construction, by which the ratio of the load-bearing capacity of the floor slab to its total mass is greater than before. At the same time, the overall height of the floor slab is clearly reduced, but the width and span are greater. In addition, the insulating capacity of the floor slab improves. Using the method, the manufacture of a floor slab is rapid and the building service systems are effectively arranged in the finished building.
  • the floor slab in intended to form a flooring deck.
  • the factory-made floor slab includes cast concrete and building service systems.
  • the cast concrete includes a ribbed slab 10 and a cast cover 11 closing the ribbed slab 10 in order to form a load-bearing hollow-core structure.
  • building service systems are arranged in the hollow cores 13 in the hollow structure formed. If necessary, feed-throughs can be made in the ribs for building service systems. Thus it is easy to install building service systems, a great deal of which will fit into the floor slab.
  • the floor slab becomes light compared to a solid structure.
  • Figure 1a shows a ribbed slab 10, which is slipform cast. Slipform casting is quick and the length of the ribbed slab can be chosen freely.
  • the ribbed slab 10 additionally includes longitudinal prestressed reinforcement 12. The length of the floor slab can then be increased further.
  • FIG 1b there is a cover 11, which is also slipform cast, cast on top of the ribbed slab 10.
  • the cover can be cast on top of all the ribs, or then the outermost ribs used as casting forms, according to Figures 1b and 1c . Independently of the application, the cover adheres to the ribs, thus forming a composite structure.
  • the thickness of a rib corresponds essentially to the thickness of the web of the ribbed slab. As does the thickness of the cover.
  • the castings then dry evenly. For example, with a thickness of 50 mm and a rib height of 230 mm a floor slab of six to seven metres will be achieved, the load-bearing capacity of which will be sufficient without intermediate supports. At the same time, space of 130 mm will remain between the web and the cover, so that drain and ventilation pipes with diameters of 110 mm and 100 mm will also fit inside the floor slab. The span can easily be increased by altering the height of the ribs.
  • the ribbed slab is cast in two parts, so that first of all a basic ribbed slab is slipformed, on top of the ribs of which additional parts are slipformed (in Figure 1a on the section lines).
  • a basic ribbed slab spans of eight to nine metres can be achieved.
  • Corresponding dimensions are 10 - 12 metres with a height of 350 mm and 16 - 18 metres with a height of 500 mm.
  • the total thickness of the floor slab can be as much as 650 - 800 mm.
  • the width of the floor slab is 2400 mm. With small changes to the casting machine a width of as much as 3000 mm can be achieved. Then using a single casting machine floor slabs of different dimensions can be made by simply altering the height of the ribs.
  • the cover 11 is already cast.
  • the building service systems are arranged in the hollow covers 13 formed in the hollow structure.
  • the building service systems are fitted to the floor slab.
  • the floor slab is then factory-made and ready for installation, containing also the building service systems.
  • An preading insulation 14 is also arranged in the hollow cores 13 of the hollow-core structure formed.
  • the ribbed slab 10 is filled with spreading insulation 14 before the casting of the cover 11. The thermal and sound insulation of the floor slab then improves.
  • the insulation supports the inner building service systems and reduces the total mass of the floor slab.
  • the insulation is preferably crushed foamed glass or a similar spreading material.
  • crushed foamed glass Due to its foamed cellular structure, crushed foamed glass is light in weight (about 190 kg/m 3 ) and extremely insulating (thermal conductivity when dry about 0.1 W/mK). In addition, crushed foamed glass settles well, which permits the cover to be cast directly on top of the crushed foamed glass. If necessary, at the hollow cores a protective fabric is used to prevent the cast concrete dropping down. In addition, the crushed foamed glass is non-combustible and completely recyclable (it does not contain organic matter). Crushed foamed glass is granular, so that the gaps between the building service systems installations are easily filled. A similar insulation can be, for example, siporex lightweight crushed concrete, or foamed crushed concrete granules, or EPS concrete. The self-weight of dry EPS concrete is about 350 kg/m 3 and its thermal conductivity about 0.08 W/mK.
  • Figure 2a shows an air-conditioning pipe 15 installed between the ribs 16, and even, if necessary, through the ribs 16.
  • the connection 17 is an air-conditioning pipe 15.
  • the feed-throughs required are machined in the cast ribbed slab. Drainpipes, electrical conduits, and other building-service-systems components can be similarly installed.
  • the gaps between the ribs 16 are filled with a spreading insulation 14, preferably crushed foamed glass.
  • the cover 11 has already been cast on top.
  • One connection opens to the upper surface of the floor slab.
  • the connection can quite as easily also open to the lower surface of the floor slab.
  • the actual floor covering comes on top of the cover.
  • the air-conditioning pipe 15 is preferably formed of two small pipes 24 and 25 ( Figure 5 ). Firstly, the small pipes can cross over each other inside the floor slab. Secondly, two small pipes are cheaper than a large pipe. In the adjacent hollow core two pipes crossing over are shown schematically.
  • the building service systems must often be taken through several floor slabs, as in the invention the floor slab contains the greatest possible share of the building service systems, such as air-conditioning pipes.
  • a factory-made floor slab must be joined to an adjacent floor slab.
  • two floor slabs 26 are set in parallel.
  • building service systems include a connection 17, the end 18 of which is arranged to be exposed for part of the distance. The connections can then be connected on the building site.
  • the end 18 is arranged in the recess 19 formed in the cast concrete.
  • the recesses in the parallel floor slabs are next to each other ( Figure 3a ).
  • Figure 3b shows a side view perpendicularly to the connections 17.
  • the larger connections are, for example, drain or air-conditioning pipes and the smaller ones electrical conduits or waterpipe casings.
  • Figure 3c is a top view.
  • the parallel floor slabs are installed with a small gap of, for example, 15 mm.
  • the distance between the outermost ribs is then, for example, 60 mm.
  • the end 18 of the connection 17 includes a joint part 20 arranged to move, which is arranged to extend to the end 22 of a corresponding connection 21 in another floor slab, to join the connections to each other.
  • the connection can then be connected easily, rapidly, and securely.
  • the depth of the recess is 180 mm, which is in practice the maximum size of the joint part. This then avoids the joint part protruding outside the external dimensions of the floor slab. With the aforementioned dimensioning, the joint part set in place extends over the ends of both connections by 50 mm, which ensures a tight connection.
  • One alternative joint part 20 is a muff, which is external in Figure 4 .
  • the muff can also be internal. In the muff there is preferably sealing and, if necessary, also tensioning means.
  • the muff's position in the finished flooring deck is shown by a broken-line rectangle.
  • the rib is cut and a separate casting wall 23 is made to limit the recess.
  • the casting wall supports the connections and also prevents the insulation from leaking out.
  • the building service systems are left partly exposed and after connecting the building service systems of adjacent floor slabs the exposed parts are covered with concrete. In other words, the recesses 19 of Figure 4 and the gap between the floor slabs are filled with a single casting.
  • Rigid connections such as drain and air-conditioning pipes, must be aligned sufficiently precisely for the joint part to be able to be moved into place.
  • Flexible electrical conduits and waterpipe casings permit a slightly greater tolerance.
  • this alignment is taken into account and otherwise too it is sought to minimize the number of joints.
  • the entire flooring deck and the floor slabs it demands are planned beforehand and the floor slabs are made at the factory read for installation. According to the invention, separate joint parts are used, which are installed when forming the deck.
  • the ends of the floor slab must be closed.
  • slipforming conventional formwork is avoided. Moulds are mainly only used at the recesses.
  • a two-part mould is placed, by which the end walls of two consecutive slipformed floor slabs are cast. The end walls become part of the composite structure.
  • the concrete casting is formed by slipforming, from which the floor slab is separated by sawing.
  • the diagonally shaded areas depict the end walls, which are separated from each other by sawing. Sawing can even be done only after the casting of the cover.
  • the thickness of the example slab shown in Figure 5 is 350 mm. Equipped with prestressed reinforcing strands, the span can be chosen to be as much as 12 000 mm.
  • the width of the floor slab 26 is increased at the same time to be 2400 mm. This is then a considerably larger slab than a normal hollow-core slab.
  • the floor slab shown is, however, suitable for transportation using normal equipment and can even be handled on site, though the floor slab weighs nearly thirteen tonnes.
  • the lower and upper strands and the cover casting mesh are joined together by dowels.
  • the same reference numbers are used for parts that are functionally the same.
  • the space left over from building service systems is filled with a suitable material, when the cover can be cast. Sound and thermal insulation also improves.
  • the space in the hollow cores can be filled with an insulating material, such as mineral wool or polyurethane. However these are expensive and placing them takes time. Some insulating material may be combustible, which increase the fire load. Preferably a spreadable and non-combustible material is used.
  • Various lightweight concretes are possible. These harden when drying and lock the building service systems in place. In lightweight concrete, the filler can be expended clay or styrox, i.e. the aforesaid EPS. When using expanded-clay concrete, protective fabric is not needed.
  • crushed foamed glass is used, which is even lighter than lightweight concrete.
  • crushed foamed glass spreads into even small holes, but does not harden. Thus in cases of possible damage the building service systems can be drilled out and locally repaired. Crushed foamed glass is then easy to remove.
  • crushed foamed glass is non-combustible and easily recycled. After compaction, the cover can be cast on top of the crushed foamed glass.
  • the ribbed slab together with the reinforcing steel is cast first. After sufficient drying, the building service systems are installed and the remaining spaces are filled with a material, such as the aforesaid crushed foamed glass. Finally the cover is cast with reinforcing mesh. If necessary, protective fabric strips or similar are used under the cover casting to prevent the cover casting seeping into the insulation. After the casting has dried sufficiently, the tension in the reinforcement is released and the tightness and joints of the connections are checked and protected during storage and transporting.
  • FIG 6a the air-conditioning pipes 15 are in two different places.
  • Figures 6a, 6b , and 7 also show the socket anchors 27, to which the lifting chains are attached.
  • the socket anchor 27 is cast between the ribs 16 as part of the floor slab 26. In the casting of the cover 11, the head of the socket anchor 27 remains in the recess. Nevertheless, the connecting part can be threaded through the head of the socket anchor. The floor slab can then be safely lifted by four socket anchors.
  • each floor slab is installed in a preplanned location and position. The protection is removed and the connections connected and the floor slabs are cast in.
  • essentially all the feed-ins inside a floor are implemented using connections inside the floor slab. This avoids separate reservations and ducts for building service systems. The making of lines and ducts on the building site is also eliminated. Between floors, one or more vertical ducts are used, the connections in which being connected to the connections coming from the deck. More generally, in a building formed of floor slabs according to the invention, a feed point 29 ( Figure 8 ) is arranged for the building service systems formed from the floor slabs 26 joined to the floor 28.
  • the hot-water line is connected to a pipe in the floor slab, which extends to the area of the deck. Similarly, the other connections are connected, so that the entire floor's deck is taken care of in a centralized manner.
  • the drainpipes and exhaust-air ducts also come to the feed point.
  • the feed point 29 is preferably formed by a shaft 30, which is arranged separately from other spaces. The building service systems can then be easily isolated and monitored. Adjustments and maintenance are also easy to do.
  • the outline of the shaft 30 is emphasized with a thick line.
  • the shaft 30 extends to the various floors of the building. Then, for example, replacement air can be distributed from the air-conditioning room through the ducts run in the shaft to the air-conditioning ducts in the decks of the various floors.
  • Figure 8 shows schematically a part of a building that is formed of the floor slabs 26 according to the invention.
  • Each floor slab 26 extends from a window 34 to the plane of the lift shafts 33.
  • Next to the lift shafts 33 is a shaft 30 according to the invention.
  • the deck is designed for each object, so that the connections are at the desired locations.
  • the replacement-air ducts are placed to open near the window's 34 surface.
  • the air-conditioning pipes being inside the floor slab 26, the replacement-air device can be placed on the lower surface of the floor slab.
  • the installation height remains low and the replacement air spreads evenly to a wide area.
  • the replacement air is preferably directed towards the window surface, thus preventing misting of the windows.
  • the replacement-air pipe 15 is lowest in Figure 8 and initially it has a size of 160 mm. The final part has a size of 100 mm and the replacement-air pipe opens close to the windows 34.
  • Figure 9 shows a side view of the same part of the building.
  • a replacement-air pipe 15 is shown, which open near the surface of the window 34.
  • an exhaust-air pipe is shown.
  • On the first floor are domestic-water pipes, which descend from the ceiling to a suitable height. In the shaft 30, each connection is connected to the vertical ducts.
  • the floor slab can also be used installed at a slant arranged as a ceiling.
  • the building service systems then contain mainly electrical cables and air-conditioning ducts, which would be difficult to implement if made in the known manner.
