Definitions

  • the invention relates to a building method comprising placing columns in a rectangular grid arrangement, fixing horizontal supporting elements to said columns and supporting concrete floors by said supporting elements, said supporting elements forming a system of girders, each provided with a number of adjacent, spaced feed-through conduits.
  • the floors consist of U- or L-shaped elements which also function as installation ducts.
  • this method is complicated and expensive.
  • the object of the invention is to avoid the above mentioned disadvantages of the known methods and to this end the building method mentioned in the preamble is characterised in that the above mentioned supporting elements provide floor elements made of prefabricated hollow elements, each element having a bottom sheet, a top sheet and spacers arranged in a grid between said sheets, the bottom sheet of each floor element having laterally projecting parts at two opposite sides; raising said floor elements until said projecting parts lie against said supporting elements; and connecting said projecting parts to the underside of said supporting elements.
  • FR-A-2142887 discloses a floor made of prefabricated hollow elements, each having a bottom sheet, a top sheet and spacers arranged in a grid shape placed between them. From this specification it is not known to connect a floor element to a supporting element by raising the floor element untill a projecting part thereof lie against a supporting element and to connect said projecting part to the underside of the supporting element.
  • the feed-through conduits are used for feeding through lines and cables.
  • the floor elements are rectangular and are fixed solely by their short sides to the girders.
  • the girders are steel section beams, they will have to (and/or can) be protected against fire.
  • the rows of spacers adjacent to the projecting parts project between the feed-through conduits of the girders, while concrete is poured in the spaces bounded by the external surface of the feed-through conduits and the end faces of the spacers projecting between the feed-through conduits.
  • the girders are preferably steel I beams.
  • the steel beams can also be channel beams, in which case a reinforced concrete is placed in the channel beam.
  • the beams can comprise two tilted channel beams held apart by transverse conduits, and the space between said beams is filled with concrete.
  • the top sheet is provided with apertures which are placed in a grid arrangement and can be covered with tile-type sheets abutting each other.
  • Figure 1 shows a perspective view of a part of a structure built according to the invention, for the sake of clarity parts of some floor elements being shown partially cut away.
  • Figure 2 is a section along the line II-II in Figure 1.
  • Figure 3 is a section along the line III-III in Fig. 1.
  • Figure 4 is a section along the line IV-IV in Figure 1.
  • Figure 5 shows a section comparable to that of Figure 4 of an alternative girder design.
  • Figure 6 shows a perspective view of a structure in which the preferred method according to the invention is used.
  • Figure 7 shows a section along the line VII-VII in Figure 6.
  • the structure shown comprises a number of columns 1, preferably of steel, placed in a rectangular grid arrangement. At each column a number of crowns 2 are placed above one another. The vertical distance between the crowns corresponds to the height of storey. Since such a system is known per se, only one column with one crown is shown in Figure 1.
  • the invention is concerned with the way in which prefabricated floor elements are supported relative to the columns 1.
  • the prefabricated floor elements are of dimensions of, for example, 720 x 240 cm.
  • girders in the form of steel channel beams 3 are fixed between the crowns 2 situated at the same level. These beams run parallel to each other, and their lengthwise direction coincides with the direction of the transverse edges of the prefabricated concrete floor elements which are fixed to the channel beams and will be described in greater detail below.
  • Each floor element comprises a bottom sheet 4, a top sheet 5, and fitted between said sheets spacers 6 in the form of lobes which are moulded onto the bottom face of the-top sheet and are in a grid arrangement.
  • the bottom sheet 4 is anchored to the lobes 6 through reinforcement ties 7 being concreted into the lobes and projecting at the bottom side, and being forced into the concrete of the bottom sheet before this concrete is set.
  • Figure 1 shows the bottom sheet 4 of a first floor element without top sheet and the bottom sheet 4 with top sheet 5 of the second floor element.
  • the top sheet is provided with apertures 8 placed in a grid arrangement and covered with tile-shaped sheets 9.
  • top sheets 5 at the transverse edges of the floor elements abut one leg of a channel beam 3, while the bottom sheets 4 at their transverse edges project under the body of a channel beam 4 at 4a up to the transverse edge of the bottom sheet 4 of another floor element.
  • each crown 2 At the position of each crown 2, a recess is provided in the corners of a floor element, into which recess a part of the crown fits.
  • the channel beams 3 are provided with transverse feed-through conduits 11 which open out into apertures 12 in the legs of the beams 3, and which serve to carry lines or cables from a hollow space of one floor element through the channel beams 3 to the hollow space of another floor element.
  • Reinforced concrete is poured into the channel beams, so that the channel beams serve as permanent falsework. If the channel beams are destroyed by fire, the concrete remains in place.
  • FIG. 5 The embodiment shown in Figure 5 is intended for higher floors. Instead of a channel beam 3, use is made of two channel beams 13 which are tilted through 90°, and between which transverse conduits 11 are welded, which conduits open out into openings in the body of the channel beams 13. Lock-woven mesh is placed in the space between the channel beams 13 and concrete is poured. The top sheets 5 are provided at their transverse edges with projecting reinforcement irons 14, the projecting part of which is embedded in the concrete between the channel beams 13.
  • the girders are in the form of I beams 20 which are fixed to the columns 1 without crowns between them.
  • the hollow floor elements comprising a bottom sheet 4, a top sheet 5, and spacers 6 placed in a grid arrangement between said sheets are fixed at their transverse end edges to the I beams 20 through the projecting parts 4a of the bottom sheet 4 being engaged with the bottom flange of the I beams and fixed by bolts 10 when the floor elements are raised.
  • the rows of spacers 6a adjacent to the projecting bottom sheet parts 4a are made elongated and project between the feed-through conduits 11. Concrete is poured into the spaces 21 bounded by the outer surface of the feed-through conduits and the end faces 6b of the spacers 6, so that the I beams 20 and the conduits 11 are completely embedded in concrete. This greatly improves fire safety.
  • the seams between the bottom sheets 4 of the floor elements are sealed with a sealer or shaped metal strip.
  • All kinds of facilities including those in the field of heating, ventilation, electricity, telephone, computers, can be accommodated in the hollow floor elements, so that a separate space for these underneath the floor is not necessary.
  • the storey height of a building can be limited as a result of this.
  • After the fitting of a floor it is possible to start immediately on the fitting of the next floor, which means that building can be speeded up considerably compared with a building system in which the floors are poured on the spot. It is possible to work immediately on each fitted floor, since there is no need to wait for setting and there are no supports on it for the next floor. If there are steel columns, they are enclosed with fire-resistant material.
