Definitions

  • the invention relates to an arrangement for producing a connection possibility, in particular for a sprinkler on a concrete or reinforced concrete floor and a method for producing the connection possibility.
  • Such arrangements are known in the prior art. These consist z. B. from a lower part of a sprinkler junction box, which is fastened by means of screws or nails on a formwork.
  • the connection cable is connected to a connection area of a fitting.
  • a transition piece is arranged, which has a receptacle for a sprinkler on the side facing away from the fitting.
  • a top of a sprinkler junction box is arranged to prevent the ingress of liquid concrete in the area of the inclusion of the sprinkler in the manufacture of concrete or reinforced concrete slab.
  • a brass closure is placed in the receptacle for the sprinkler, so that the recording is protected from dirt.
  • the compound thus prepared is connected to the lower part of the sprinkler connection box in such a way that the upper and lower part of the sprinkler connection box are connected to one another in a concrete-tight manner.
  • a disadvantage is seen in the fact that after arranging several arrangements for the possibility of connecting Sprinklem on a shuttering also due to the large number of lines that are laid on the casing, it is difficult to detect the exact position and to check whether all connection options were laid. Furthermore, there is the problem that after curing of the concrete, the casing is removed and the lower parts of the sprinkler connection boxes are attached to this. Thus, these are removed with the shuttering from the tops of the sprinkler connection boxes, without special care must be taken at these locations in order to avoid damage to the tops that remain in the concrete ceiling. Furthermore, it is in most cases not possible to reuse the lower parts of the sprinkler junction boxes in another ceiling, because they are destroyed or damaged due to the force. This is where the invention, which has set itself the task of avoiding the disadvantages of the prior art.
  • the box surrounding the fastener partially rests on the casing and is pressed over the fastener by means of the fastener against the shuttering, when pouring the concrete no concrete can penetrate into the box and thus the fastener and the second connection area of the fitting free of concrete deposits being held.
  • the fastener after curing of the concrete and the removal of the casing is removable and reusable.
  • screw connections between the fitting and fastener or fitting and adapter and / or adapter and extension element allow easy assembly and disassembly.
  • the fastening means is a female threaded nut. This can be screwed onto the threaded portion of the fastener and thus provides a simple and cost-effective way of attachment.
  • a washer between the nut and the casing in order to prevent penetration into the usually made of wood casing and to ensure easy disassembly. Also, a too large opening in the casing can be covered with the washer, so that a secure tightening of the fastening means, in particular the mother can be ensured.
  • the invention comprises a method for producing a connection possibility for a sprinkler on a limited by a formwork concrete or reinforced concrete ceiling.
  • the method provides that first a fastener is connected to a first terminal portion of a fitting.
  • the fitting may be a bend or branch, in particular a T-piece.
  • a can is arranged via the fastening element, which is essentially cylindrical and has at one end a wall provided with an opening.
  • the breakthrough is designed so that the can is tightly applied to a collar of the first connection area of the fitting.
  • the cylindrical portion of the can surrounds a part of the fastening element, so that an annular cavity is enclosed.
  • the fastener overhangs the can after it abuts the collar of the first port of the fitting.
  • This projecting portion of the fastener is then passed through an opening in the formwork. For this it is necessary in advance that this opening is introduced into the mostly made of wood casing.
  • the fastener After the fastener has been passed through the opening, it is fastened on the side facing away from the fitting of the casing by means of a fastening means. Thereafter, the connection between at least one water pipe and a second connection region of the fitting is made. Now further laying work can be carried out on the shuttering. Also, reinforcement mats can be introduced, which increase the stability of the ceiling. Thereafter, the concrete is placed on the formwork. This can not penetrate into the can, which is thereby pressed onto the casing by the attachment by means of a fastening means on the side facing away from the fitting, so that no concrete can reach the second connection region of the fitting and the fastener.
  • the fastener After curing of the concrete, the fastener can be removed from the fitting.
  • the shuttering can be removed from the ceiling without regard to the connection possibilities for the sprinklers.
  • a sprinkler is connected to the first connection area of the fitting. Since the sprinkler body must be located below the ceiling, it may be necessary to insert an adapter between the sprinkler and the first connection area of the fitting.
  • This adapter can be designed so that also diameter differences between the connection areas of the fitting and the sprinkler can be bridged. In this regard, it has been recognized that the adapter is connected either first to the sprinkler and then both together to the first port of the fitting, or first to connect the adapter to the first port of the fitting and then the sprinkler to the adapter.
  • the fastening element is constructed from two parts.
  • the fastening element consist of an adapter and an extension element. Since it is necessary in most applications to place an adapter between the first connection region of the fitting and the sprinkler, this can already be introduced as part of the fastening element. Since this adapter is completely surrounded by the box, it is not possible to pass through the formwork. To still ensure this, the adapter is connected to an extension element that bridges the missing length. It has been recognized that both the adapter with the first terminal portion of the fitting or first the adapter with the extension element can be connected.
  • a releasable connection in particular a screw connection, is necessary between the adapter and the extension element.
  • connection option 1 shows a section through a mounted on a formwork (7) inventive arrangement for producing a connection option is shown.
  • the arrangement has a fitting (3), which is T-shaped, with three connection areas (2a, 2b). But it is also possible that the fitting (3) has only two connection areas (2a, 2b), so that no forwarding of the fluid to further arrangements is possible.
  • pipelines (1) are arranged, which in this example are fixed to the fitting (3) by means of sliding sleeves.
  • a fastening element (4a, 4b) which consists of an adapter (4a) and an extension element (4b), releasably secured.
  • both fitting (3) and adapter (4a) and adapter (4a) and extension element (4b) are connected to each other via a screw connection.
  • the adapter (4a) is designed to be a kind of reducer, since the connection region (2a) of the fitting (3) has a larger dimension than the later-to-be-attached sprinkler.
  • the arrangement has a can (5) which surrounds the fastening element (4a, 4b) in regions.
  • This can (5) is arranged on a collar (6) of the connection area (2a) of the fitting (3) which is not connected to a pipeline (1), so that its position relative to the fitting (3) is defined.
  • the can (5) is made of metal, but there are also other materials conceivable that meet the requirements in case of fire and do not cause functional limitations of the sprinkler in case of fire. It is also possible, as in this example, to arrange a seal (12) between the can (5) and the collar (6) of the fitting (3) in order to reliably prevent the penetration of concrete at this point.
  • FIG. 1 also shows a formwork (7) through which the fastening element (4a, 4b), in particular the extension element (4b), projects.
  • the formwork (7) has an opening (9) which is substantially identical in shape and surface area to the cross-section of the fastening element (4a, 4b), in particular of the extension element (4b).
  • a fastening means (8) in the form of a nut is arranged on the fastening element (4a, 4b).
  • the latter is connected to the fastening element (4a, 4b), in particular the extension element (4b), via the thread located in the end of the extension element (4b) facing away from the fitting (3) in this exemplary embodiment.
  • fastening means (8) such as terminals or the like possible.
  • a washer (10) with a larger diameter than the nut is arranged between the casing (7) and the nut as fastening means (8). This prevents that when tightening the nut this in the casing (7), which is usually made of wood, digs and thus complicates a later release.
  • an easily detachable sealing means in particular a Teflon tape
  • the adapter (4a) when disassembling the extension element (4b) should not be unscrewed.
  • the adapter (4a) should be fluid-tightly connected to the fitting (3).
  • the use of a hard-to-release sealant, especially hemp has proven to be beneficial.
  • connection region (2a) of the fitting (3) is connected to the adapter (4a) via a screw connection. It can be introduced into the thread for sealing hemp, which expands by fluid intake and thus seals the connection. But there are also other sealants conceivable. In this connection, it is also possible to seal the connection between adapter (4a) and connection region (2a) of the fitting (3) by means of an additional or sole adhesive connection.
  • connection portion (2a) of the fitting (3) and the fastener is necessary because the fastener must be removed after completion of the concrete or reinforced concrete ceiling.
  • the extension element (4b) is releasably connected to the adapter (4a) via a screw connection.
  • the connection region of the connecting element (4b) to the adapter (4a) is designed in the same diameter as the later to be used sprinkler. Due to the division of the fastening element (4a, 4b), it is possible to use only different adapters (4a) for different dimensions of the connection regions (2a) of the fitting (3), whereas in the number of variants the extension element (4b) only applies to the different sprinkler dimensions must be coordinated.
