Definitions

  • a method and device for laying waste pipes in hollow flooring blocks is a method and device for laying waste pipes in hollow flooring blocks.
  • the present invention relates, to a method for laying waste pipes, waste-water pipes and the like in the hollow channels of hollow flooring slabs or blocks.
  • the invention also relates to a novel device for facilitat ⁇ ing adjustment of the.fall of the pipes.
  • hollow decks are produced by concrete manufac ⁇ turing industries the world over, for use as flooring slabs in building construction work.
  • hollow-deck is meant a prefabricated concrete slab or block of desired dimensions, in which elongated, hollow channels are formed, in order to reduce the weight of the concrete blocks. These channels may have a circular, and ellipti ⁇ cal or a square cross-section.
  • One problem arising from the use of such hollow-decks in the construction of flooring structures resides in the laying of waste pipes or corresponding conduits in the floor. Normally, these hollow-decks are smoothed-off with a top layer of con ⁇ crete, to a thickness of about 50 mm, which does not leave room in which waste pipes can be laid.
  • the present invention affords a solution to the afore ⁇ said problems associated with present day methods of laying waste pipes in buildings, irrespective of whether the buildings are intended as dwelling houses or in ⁇ tended for some other purpose.
  • the method offers a flexible system for laying waste pipes in buildings of basic concrete construction, in which the floor struc ⁇ tures comprise so-called hollow decks, as hereinbefore defined.
  • the inventive method has the characteristic features set forth in the following claims and a device has been invented which will ensure that pipes of mutually different lengths will be laid with the correct pipe fall.
  • the inventive method enables wet rooms to be located anywhere in a building which comprises floor structures in which hollow channels extend over the whole of the structure.
  • the building concerned is provided along the whole of its length with so-called pipe-slots intended for accommodating main collecting pipes, on a level with the respective floor structures of the building.
  • the hollow channels incorporated in the floor structures are intended to open into these slots.
  • water closets are the most difficult to position, be ⁇ cause they require the largest (diameter) waste pipes.
  • the present invention will be described with reference to waste pipes which extend from a water closet. Accordingly, the following description relates to the steps which need to be followed when installing waste pipes of requisite size in hollow channels of common or standard dimensions.
  • a hole preferably a central hole
  • a so-called concrete drill i.e. a core-removing tube drill
  • the waste pipe which is passed in through the aforesaid pipe-slot and into a hollow channel, is preprepared by connecting to a straight waste pipe of requisite length pipe-bends which together form an angle of about 90° to the longitudinal axis of the straight pipe length.
  • This pipe assembly is then passed into the hollow channel, with the pipe-bend first, whereafter a moulded fitting is coupled to the outer end of the pipe.
  • a moulded fitting is coupled to the outer end of the pipe.
  • the fitting at the outer end of the pipe is then con ⁇ nected to a collecting pipe, or to a main waste pipe, located in the aforesaid pipe-slot, with the aid of a further pipe-bend, pipe-elbow or some other device.
  • the pipes used in accordance with the invention prefer ⁇ ably lack muff-couplings and are therefore preferably joined together with the aid of so-called sweep coup ⁇ lings, for instance couplings of the kind described and illustrated in Swedish Patent Specification No. 338019.
  • These couplings include rubber cuffs or plastic cuffs which lie in abutment with the pipes, and hence sound vibrations occurring in the pipes will be dampened such as to prevent the transmission of said vibrations to the building framework.
  • the waste pipes will thus hang freely in the hollow channels between the sweep coup ⁇ lings, therewith minimizing the possiblity of pipe acoustics converting to building framework acoustics.
  • the hole is first lined with a filling box, preferably in the form of a cylindrical mould having two radially spaced and mutually coaxial cylin ⁇ drical sleeve-like elements of mutually different dia ⁇ meter which are interconnected by an intermediate, annular and horizontal element.
  • the sleeve of smallest diameter is placed in the hole, so that the horizontal element will abut the upper surface of the floor.
  • the cylindrical sleeve having the larger diameter forms a hollow mould when applying an upper concrete surface to the concrete flooring slabs.
  • the filling box is provided with a loose mould bottom which includes a hole through which the pipe-bend can pass and which will enable future relocation of the waste pipe, on which relocating-occasion the hole lead ⁇ ing to the underlying hollow channel can be filled-in, without needing to fill-in the hollow channel with concrete.
  • the lower part of the filling box is filled with mineral wool or some other sound insulating material.
  • the means by which the pipe-bend is secured in said hole Prior to applying a surface layer to the floor of the wet room, the means by which the pipe-bend is secured in said hole is placed in its permanent position, where ⁇ after the upper part of the moudling box is filled with a readily-broken concrete mass, for instance concrete which contains LecaKulor .
  • the water closet is then installed in a conventional manner, prior to smooting- off the concrete floor.
  • Figure l illustrates schematically three hollow decks fitted with collecting pipes and main pipes
  • Figure 2 is a schematic, cross-sectional view of a hollow channel in which a preassembled waste pipe has been inserted;
  • Figure 3 is a view corresponding to the view of Figure 2 and showing a waste pipe fixed in position and connected to a main pipe;
  • Figure 4 is an enlarged, fragmentary view of a waste pipe, showing the attachment of the leading pipe-bend fitted thereto.
  • the building in which the inventive method is applied will have provided in an outer wall surface thereof a number of so-called pipe-slots 3 in which collecting pipes 4 are fitted.
  • the number of pipe-slots formed in said outer wall will equal the number of floors of the building.
  • the floors are constructed from so-called hollow decks 1 which incorporate hollow channels 2, and the collecting pipes 4 are connected to waste pipes 5.
  • the pipe-bends are connected to the pipe 6 by means of so-called sweep couplings 9, 10 which include inwardly lying rubber cuffs.
  • a reducing pipe 12 is connected to the outer end of the pipe 6 in a corresponding manner, with the aid of a sweep coupling 11. This reducing pipe bridges the change in dimensions between, for instance, the diameter of the collecting pipe 4, this diameter being 110 mm and the diameter of the waste pipe 6, a diameter of 75 mm.
  • the pipe-bend 8 When the waste pipe 6 has been inserted fully into the hollow channel 2, the pipe-bend 8 is located immediately beneath a hole 13, preferably a circular hole, which has been sunk from the hollow-deck 1 into the hollow passage 2.
  • a filling box 14 Placed in the hole 13 is a filling box 14, which comprises two cylindrical, mutually coaxial sleeves interconnected by a horizontal annular element.
  • the sleeve of smaller diameter 15 is operative to line the hole 13, with the annular part 16 of said box lying against the upper surface of the hollow-deck 1, such that the sleeve of larger diameter 17 will protrude above said surface and therewith form a hollow mould or filling space into which concrete is filled during the subsequent casting of surface concrete.
  • the sweep coupling 10 is provided with a screw- tightening means 19 for tightening the coupling around the mutually opposing ends of the pipe-bends 7 and 8.
  • a screw- tightening means 19 for tightening the coupling around the mutually opposing ends of the pipe-bends 7 and 8.
  • a loose, perforated mould bottom 20 is fitted over the end of the pipe-bend 8 and placed on a flange 21 which extends radially inwards from the sleeve of smaller diameter 15.
  • the mould bottom 19 has provided therein a slot through which the arm 18 extends from the screw-tightening device 19.
  • the elongated arm 18 has an angled upper part in which a slot 22 is for ⁇ med.
  • This slot is intended to receive a steel rod 23, preferably clad with rubber, which is sufficiently long to enable both ends of the rod to rest on the annular part 16.
  • the rubber cladding on the rod 23 will effec ⁇ tively dampen vibrations, so as to prevent transmission of vibrations from the pipe to the hollow deck.
  • a connecting pipe 24 is then fitted to the pipe-bend or pipe-elbow 8, whereafter the lower part of the filling box 14 is filled with sound insulating material and the upper part of the filling box is filled with smoothing cement or mortar, whereafter the floor of the wet room can be completed and the sanitary appliance or appliances may be put in place.
  • the reducing pipe 12 is connected to the main pipe 4 in the pipe-slot 3, with the aid of an 87° pipe-bend 25.
  • the pipe- slots 3 are filled with insulating material 26 and covered with an openable facade element 27.
  • the inventive method enables pipes 6 of varying lengths to be used, and the length of the pipe will depend on the distance of the sanitary appliance concerned from the outer wall surface of the building.
  • the arm 18 can be standardized so that when suspended from the rod 23 located in the slot 22, the shortest, length of pipe 6 used will obtain a standard pipe-fall.
  • the slot angle tapers slightly towards the longitudinal axis of the arm 18.
  • the arm 18 is preferably provided with a number of axially spaced holes.
  • the requisite pipe-fall is obtained by inserting the rod 23 through an appropriate hole in the arm 18, such as the illustrated hole 28. It will be understood that the number of holes provided in the arm 18 and the spacing therebetween will correspond to the correct pipe-fall for standardized lengths of waste pipe 6.

Abstract

Lorsqu'on pose des tuyaux d'écoulement d'eau dans des structures dites de plancher creux, on munit un tuyau d'écoulement droit (6) d'un moulage (12) et d'un coude de tuyau (7, 8) pour le relier respectivement à un tuyau collecteur d'eau (4) et une installation sanitaire. On introduit le tuyau d'écoulement (6) dans un canal creux (2) de la structure du plancher (1), en commençant par le coude de tuyau (7, 8), après quoi on soulève le coude de tuyau (7, 8) par un trou que l'on a percé depuis la surface du plancher dans le canal creux sousjacent et on le fixe dans le trou. On peut ensuite relier l'installation ou l'appareil sanitaire au coude de tuyau (7, 8) et le moulage au tuyau collecteur (4). On fixe le coude de tuyau (7, 8) dans le trou à une hauteur donnée au moyen d'un élément (18) ayant la forme d'un bras en L inversé.
