Definitions

  • the invention relates to an assembly for creating a connection, in particular for a sprinkler on a concrete or reinforced concrete ceiling, and a method for producing the connection.
  • Such assemblies are known from the prior art. They include, for example, a lower part of a sprinkler connector box that is attached to a casing with the aid of screws or nails.
  • a connection pipe is connected to a connection interface of a fitting.
  • An adapter having a receptacle for a sprinkler on the side facing away from the fitting is disposed on a second connection interface of the fitting.
  • An upper part of a sprinkler connection box whose purpose is to prevent liquid concrete from penetrating into the sprinkler region of the receptacle during production of the concrete or reinforced concrete ceiling is disposed above this receptacle.
  • a brass seal is disposed in the sprinkler receptacle such that the receptacle is protected from dirt.
  • the resulting connection is connected to the lower part in such a way that the upper and lower parts of the sprinkler connection box are connected to one another in a manner which prevents the intrusion of liquid concrete (i.e., in a concrete-tight fashion).
  • the object of the present invention is to prevent the disadvantages found in the prior art.
  • the disadvantages of the prior art are avoided in that the fastening element is inserted through the mold, thus allowing the position of each connection to be monitored at all times from below without a time-consuming search in the pipes and reinforcements laid in the mold.
  • the fastening element may be removed and reused after the concrete has cured and the mold has been removed.
  • the use of a two-part fastening element may be favorable. This is especially true if the second connection interface of the fitting is designed with a larger diameter than the connection interface of the sprinkler to be inserted.
  • an adapter adapted to the diameter of the sprinkler may be used to provide a corresponding diameter reduction.
  • this adapter may be used at the same time for connection to the sprinkler.
  • the adapter may not be designed with a length that it allows it to be fastened on the side of the mold facing away from the fitting.
  • an extension element is therefore provided that is connected to the adapter.
  • the extension elements are therefore still required only for the diameter dimension of the diameters of the connection interfaces of the sprinklers.
  • the adapter is completely surrounded by the box.
  • screw connections between the fitting and the fastening element or the fitting and the adapter and/or the adapter and extension element allow for simple installation and removal.
  • the box may be pressed against the mold in a defined fashion.
  • the fastening means prefferably be a nut having an inner thread.
  • This inner thread may be screwed onto the threaded section of the fastening means, thus representing a simple and cost-effective fastening option.
  • a washer may be disposed between the nut and the mold in order to prevent penetration into the mold, which is usually made of wood, and to guarantee simple removal.
  • the washer may also be used to cover an oversized opening in the mold so as to guarantee a secure tightening of the fastening means, in particular the nut.
  • the invention further relates to a method for creating a connection for a sprinkler to a concrete or reinforced concrete ceiling bordered by a mold.
  • the method provides for a fastening element to first be connected to a first connection interface of a fitting.
  • This fitting may be an elbow or a branch line, in particular a T piece.
  • a box is disposed via the fastening element, the box having an essentially cylindrical design and a wall provided with an opening on one end.
  • the opening is structured such that the box may be placed tightly against a collar of the first connection interface of the fitting.
  • the cylindrical region of the box surrounds a part of the fastening element, such that a circular hollow space is enclosed.
  • the fastening element protrudes past the box after its placement on the collar of the first connection interface of the fitting.
  • This protruding region of the fastening element is subsequently guided through an opening in the mold.
  • this opening be inserted in advance into the mold, which is usually made of wood.
  • the fastening element After the fastening element has been inserted through the opening, it is fastened on the side of the mold facing away from the fitting using a fastening means. Then at least one water pipe is connected to a second connection interface of the fitting. Now, additional placement work may be performed on the mold. Reinforcement meshes may also be inserted, which increase the stability of the ceiling. Then the concrete is poured into the mold.
  • the concrete is not able to penetrate through the fastening by a fastening means on the side of the mold facing away from the fitting and into the box, which is pressed against the mold by said fastening means, such that no concrete is able to penetrate to the second connection interface of the fitting and fastening element.
  • the fastening element may be removed from the fitting.
  • the mold may be removed from the ceiling without regard to the connections for the sprinklers.
  • the sprinkler is subsequently connected to the first connection interface of the fitting. Because the sprinkler body must be disposed below the ceiling, it may be necessary for an adapter to be inserted between the sprinkler and the first connection interface of the fitting.
  • This adapter may be designed such that it is able to bridge differences in diameter between the connection interfaces of the fitting and the sprinkler.
  • the adapter is either first connected to the sprinkler and then the two pieces together are connected to the first connection interface of the fitting or the adapter is first connected to the first connection interface of the fitting and then the sprinkler is connected to the adapter.
  • the fastening element may be comprised of two parts.
  • the fastening element may comprise an adapter and an extension element. Because, in most cases, it is necessary to dispose an adapter between the first connection interface of the fitting and the sprinkler, the adapter may already be inserted as a part of the fastening element.
  • the adapter is completely surrounded by the box, insertion through the mold is not possible. In order to nevertheless guarantee insertion, the adapter is connected to an extension element that bridges the missing length. It was realized that it is possible to first connect the adapter to the first connection interface of the fitting or to first connect the adapter to the extension element.
  • a detachable connection in particular a screw connection, is necessary between the adapter and the extension element.
  • FIG. 1 Section through an assembly according to the invention for creating a connection, in particular for a sprinkler on a concrete or reinforced concrete ceiling, mounted on a mold.
  • FIG. 1 shows a section of an assembly according to the invention for creating a connection mounted on a mold ( 7 ).
  • the assembly comprises a fitting ( 3 ) designed in a T shape and having three connection interfaces ( 2 a , 2 b ).
  • the fitting ( 3 ) it is also possible for the fitting ( 3 ) to comprise only two connection interfaces ( 2 a , 2 b ) such that it is not possible to conduct the fluid to additional assemblies.
  • Pipes ( 1 ) are disposed on two of the connection interfaces ( 2 b ) of the exemplary embodiment which, in this example, are fixed to the fitting ( 3 ) with the aid of sliding collars.
  • a fastening element ( 4 a , 4 b ) comprising an adapter ( 4 a ) and an extension element ( 4 b ) is fastened in a detachable fashion to the connection interface ( 2 a ) of the fitting ( 3 ) that is still free.
  • the fitting ( 3 ) and adapter ( 4 a ) as well as the adapter ( 4 a ) and the extension element ( 4 b ) are connected to one another via a screw connection.
  • the adapter ( 4 a ) is structured in such a way that it represents a sort of reduction adapter because the connection interface ( 2 a ) of the fitting ( 3 ) has a larger diameter than the sprinkler to be attached later.
  • the assembly has a box ( 5 ) that surrounds the region of the fastening element ( 4 a , 4 b ).
  • This box ( 5 ) is disposed on a collar ( 6 ) of the connection interface ( 2 a ) of the fitting ( 3 ), which is not connected to a pipe ( 1 ), in such a way that its position is defined relative to the fitting ( 3 ).
  • the box ( 5 ) is made of metal; however, other materials that comply with fire regulations and do not limit the functionality of the sprinkler in the case of a fire are conceivable as well.
  • a seal ( 12 ) to be disposed between the box ( 5 ) and the collar ( 6 ) of the fitting ( 3 ), as in this example, in order to reliably prevent concrete from penetrating at this location.
  • FIG. 1 also shows a mold ( 7 ) through which the fastening element ( 4 a , 4 b ), in particular the extension element ( 4 b ), protrudes.
  • the mold ( 7 ) has an opening ( 9 ) that is essentially identical in its shape and area to the cross section of the fastening element ( 4 a , 4 b ), in particular the extension element ( 4 b ).
  • a fastening means ( 8 ) in the form of a nut is disposed on the fastening element ( 4 a , 4 b ) on the side of the mold ( 7 ) facing away from the fitting ( 3 ).
  • This fastening means is connected to the fastening element ( 4 a , 4 b ), in particular the extension element ( 4 b ), via the thread located on the end of the extension element ( 4 b ) facing away from the fitting ( 3 ) in this exemplary embodiment.
  • other fastening means ( 8 ) such as clamps or the like, are possible as well.
  • a washer ( 10 ) having a larger diameter than the nut is disposed between the mold ( 7 ) and the nut being used as the fastening means ( 8 ). This washer prevents the nut from digging into the mold ( 7 ), which is usually made of wood, thus impeding later removal.
  • the adapter ( 4 a ) In order to be able to easily detach the extension element ( 4 b ) from the adapter ( 4 a ) when removing it, it has been shown to be advantageous for an easily removable sealing means, in particular a Teflon band, to be inserted into the thread. In contrast, the adapter ( 4 a ) should not be unscrewed during the removal of the extension element ( 4 b ). The adapter ( 4 a ) should also be connected to the fitting ( 3 ) in a fluid-tight manner. The use of a sealing means that is difficult to remove, in particular manila, has been shown to be favorable for this purpose.
  • connection interface ( 2 a ) of the fitting ( 3 ) is first connected to the adapter ( 4 a ) via a screw connection.
  • manila which expands when it absorbs liquid, may be placed in the thread for sealing purposes, thus sealing the connection.
  • other sealing materials are conceivable as well.
  • the connection between the adapter ( 4 a ) and the connection interface ( 2 a ) of the fitting ( 3 ) may be connected in a sealing fashion by means of an additional adhesive connection or by means of the adhesive connection alone.
  • connection interface ( 2 a ) of the fitting ( 3 ) and the fastening element is necessary because the fastening element must be removed again after completion of the concrete or reinforced concrete ceiling.
  • the extension element ( 4 b ) is connected to the adapter ( 4 a ) in a removable fashion via a screw connection.
  • the diameter of the connection interface of the connection element ( 4 b ) to the adapter ( 4 a ) is structured precisely in the same manner as the sprinkler to be inserted later.
  • the box ( 5 ) is now slid over the fastening element ( 4 a , 4 b ) with a seal ( 12 ) until the box ( 5 ), along with the seal ( 12 ), rests against the collar ( 6 ) of the connection interface ( 2 a ) of the fitting ( 3 ).
  • a seal ( 12 ) it is not strictly necessary to use a seal ( 12 ). This is particularly advantageous if the composition of the concrete requires additional sealing.
  • the fastening element ( 4 a , 4 b ), in particular the extension element ( 4 b ) is guided through an opening ( 9 ) placed in the mold ( 7 ).
  • This opening ( 9 ) corresponds approximately to the cross section of the fastening element ( 4 a , 4 b ), in particular of the extension element ( 4 b ).
  • a fastening means ( 8 ) is connected to the fastening element ( 4 a , 4 b ), in particular to the extension element ( 4 b ), on the side of the mold ( 7 ) facing away from the fitting ( 3 ).
  • connection is embodied as a screw connection, with the fastening element ( 4 a , 4 b ), in particular the extension element ( 4 b ), having a thread on its side facing away from the adapter ( 4 a ) and with the fastening means ( 8 ) being embodied as a nut.
  • a washer ( 10 ) is disposed between the mold ( 7 ) and the nut.
  • the box ( 5 ) is fixed on the mold ( 7 ) via the fastening means ( 8 ), such that it is not able to float when the concrete is poured and such that no concrete is able to penetrate between the mold ( 7 ) and the box ( 5 ).
  • pipes ( 1 ) are connected to the connection interface(s) ( 2 b ) that are still free. In general, this is accomplished by expanding the end of the pipe and sliding it onto the connection interface ( 2 b ) of the fitting ( 3 ). Then the end of the pipe is compressed with the fitting ( 3 ). This may be accomplished using a radially compressible pressing sleeve or by using a sliding collar ( 11 ).
  • the pipes ( 1 ) are usually laid in such a way that a closed ring results between the individual assemblies, said ring having a feed from one side or from two sides, or individual lines that are fed from only one side. From these assemblies, the fitting designs result that are to be used for the individual assemblies.
  • a pressure test is conducted, in particular in accordance with VdS CEA 4001. This test allows any non-tight points to be recognized and repaired before the concrete is poured.
  • the fastening element ( 4 a , 4 b ) serves as a stopper that seals off the connection interface to which the sprinkler will later be connected from its surroundings, thus allowing the pressure test to be conducted. If no drop in pressure, or a drop in pressure lying within the tolerance range, is detected, then the concrete may be poured into the mold ( 7 ).
  • an additional pressure test in particular in accordance with VdS CEA 4001, is conducted. This test serves to check the impermeability. Then the concrete must dry and cure. Once this has occurred, the fastening means ( 8 ), in particular the nuts, may be removed. Now the mold ( 7 ) and the fastening elements ( 4 a , 4 b ), in particular the extension elements ( 4 b ), may be removed. Subsequently, a sprinkler is connected to the free connection interface ( 2 a ) of the fitting ( 3 ) or the adapter ( 4 a ). In cases in which, for visual reasons, the box ( 5 ) is not to be openly recognizable in the concrete or reinforced concrete ceiling, it may be covered before the sprinkler is attached.
