Description

The The present invention relates to a method of assembly Inserting a hollow body in a concrete wall or concrete ceiling. In particular, the present invention relates to a method for Inserting a mounting rail or an installation box in one Wall or ceiling. Furthermore, the present invention relates an assembly auxiliary element, with the present invention a appropriate assembly is facilitated.

In the lighting technology or in general in home automation often hollow body-like elements in a wall or ceiling a room arranged. On the one hand, this can be a classic one Installation boxes for receiving connection devices for power supply or signal transmission or for the arrangement of switching or operating elements act. Also often sunk in a ceiling so-called. DIN rails arranged, which serve for receiving example. Of busbars. These Busbars then allow flexible connection of consumers, in particular lights, spotlights or the like Devices.

The Introducing these hollow bodies in walls or ceilings can be done, for example, that in the wall or ceiling a corresponding Recess is created, in which the hollow body is then inserted and is fastened in a suitable manner. This can, for example, by doing so take place that introduced into the wall or ceiling recess is larger than the outer dimension of the hollow body. The remaining space is then with filled a suitable self-curing material.

The just described procedure for introducing hollow bodies in walls or ceilings is relative consuming and furthermore only meaningful to carry out, if then the wall or ceiling is plastered. By applying the plaster can namely the curing Material in the remaining cavity of the recess laminated so that in this way the front of the hollow body flush with the wall surface can. However, the method is not applicable if no additional plaster can be applied to the wall or ceiling should. In particular, so-called. Concrete applications results Accordingly, the problem that the procedure described above not leads to a visually satisfactory solution.

To circumvent this problem, is in the DE 43 12 661 A1 proposed to pour a to be arranged in a concrete wall installation box directly into the concrete wall. For this purpose, the can is provided on its front with an essay, which is connected to a shuttering to create the concrete wall, in particular screwed. In this state, the concrete wall is then poured, and after hardening of the wall, the casing is removed. On the front side of the box a predetermined breaking point is designed for this purpose, so that at the same time an approximately circular cover is removed from the box when removing the casing.

The in the DE 43 12 661 A1 Accordingly, the solution described circumvents the problem that a recess must be introduced into an already finished wall, in which then the can is retrofitted. The problem, however, is that a clean separation of the circular cover at the predetermined breaking points is difficult to achieve. In particular, there is a risk that the can is damaged when stripping the wall, which again leads to an optically inadequate arrangement.

Of the The present invention is accordingly based on the object an improved method for mounting or for introducing hollow bodies in a concrete wall or concrete pavement.

The inventive solution is based first again on the idea to introduce the hollow body with Concrete to cast a clean arrangement inside to achieve the concrete wall or concrete pavement. According to the invention however, the corresponding holding of the hollow body during the Casting the wall or ceiling now with the help of a special Mounting auxiliary elements, which on the one hand to the shuttering to Creating the concrete wall or concrete ceiling is fixed and on the other hand solvable is connected to the hollow body to be introduced. This Mounting auxiliary element can then when stripping the wall or ceiling completely removed from the hollow body again be without the auxiliary element or the hollow body is damaged. The invention Procedure thus leads to an extremely satisfactory result in terms of the arrangement of the hollow body. At the same time there is a further advantage in that the mounting auxiliary element can be used repeatedly because this is not damaged becomes.

According to a first aspect of the present invention, accordingly, a method for mounting or for introducing a hollow body, in particular a mounting rail or an installation box, proposed in a concrete wall or concrete pavement, wherein a mounted on a shuttering to create the concrete wall or concrete ceiling mounting auxiliary element releasably connected to the hollow body to be introduced and then the concrete wall or concrete pavement is poured, and wherein when stripping the concrete wall or concrete cover the mounting auxiliary element is completely removed again from the hollow body.

Further According to the invention, an assembly auxiliary element for mounting or for introducing a hollow body, in particular a mounting rail or an installation box, in a concrete wall or concrete ceiling, wherein the auxiliary assembly element means to attach to a formwork to create the concrete wall or concrete ceiling and means for holding the hollow body to be introduced during the casting of the concrete wall or concrete pavement and wherein the means for holding the hollow body to be introduced are configured such that the mounting auxiliary element when stripping the wall or ceiling automatically from the introduced hollow body is removed again.

Preferably is the mounting auxiliary element designed such that this with the hollow body to be introduced locked or clamped is. In this way, the stripping of the Wall or ceiling done. The hollow body to be introduced is preferably in a connected to the mounting auxiliary element Condition flush with the shuttering. In this way will on the one hand ensures that no concrete in the interior of the hollow body but at the same time, this is how it works in a simple way a flush arrangement of the front achieved the hollow body with the wall or ceiling.

As already mentioned it can be, for example, in the wall or Ceiling hollow body around a U-shaped Support rail act, which provided for holding a busbar is. In this case, the mounting auxiliary element is, for example, by a elongated profile body formed, preferably Locked by means of spring elements with the mounting rail becomes. The spring elements can temporarily attached to the rail, for example. Via a screw become.

According to one second advantageous variant of the present invention it is the case to be introduced hollow body to an installation box, which at its front a so-called. Eingießmontageteil having. The auxiliary assembly element is in this case by a So-called centering formed. It can be complementary in this case be provided that one to the surface of the concrete wall or concrete ceiling facing side of the installation box with a Insert is provided, which in addition to the shuttering may be connected and, for example, by means of corresponding weakenings or predetermined breaking points is designed such that this use in the Stripping is removed automatically. In this case too, however the actual assembly auxiliary element, namely the centering plate not damaged during stripping and can be used repeatedly.

Based on 1 to 5 will be explained below, a first embodiment of the method according to the invention, in which a support rail is to be arranged in a concrete ceiling.

The generally with the reference numeral 1 designated and in the 2a and 2 B For example, illustrated support rail is formed by an aluminum profile, which with its two side walls 2 and a bottom side 3 has a U-shape open in the mounted state to the bottom. As shown in 5 is the interior 4 the mounting rail 1 for receiving a busbar 10 intended. This is a elongated plastic part, which opposing recesses 11 having. Within these elongated recesses 11 run wires (not shown) that can be contacted by consumers of the system to be powered or to receive data signals. Further recesses of the busbar 10 can be provided for engagement of support members, so that in a simple manner corresponding consumers, for example. Spotlights or lights can be mechanically fixed and at the same time a corresponding contact is ensured. The busbar 10 is here by means of screws 9 , which in one at the bottom side 3 the mounting rail 1 arranged screw channel 6 intervene, on the rail 1 attached.

Such mounting rail systems are already well known and can, for example. In suspended form spaced from a ceiling can be arranged. In the present case, however, according to the illustration in 5 the rail 1 inside a concrete ceiling 100 be arranged, in such a way that the underside of the rail 1 flush with the ceiling 100 concludes. For this purpose, a special assembly method is proposed according to the invention, which will be explained below.

The solution according to the invention is based on the use of a mounting auxiliary element 15 , which in the 1a and 1b is shown. This assembly auxiliary element 15 is also configured in the form of a U- or C-shaped rail, wherein in the bottom side at regular intervals longitudinal bores 17 are formed. With the help of these holes, the rail 15 as shown in the 3 and 4 on a formwork 101 for the formation of the later concrete ceiling 100 by means of screws 19 be screwed on. At the same time, the mounting auxiliary element 15 however, also detachable with the mounting rail 1 get connected. This is done via spring elements 20 , which - for example, at a distance of 20 cm - temporarily on the mounting rail 1 be attached. The attachment of these spring elements 20 again by means of screws 9 , which in the screw 6 at the bottom side 3 the mounting rail 1 intervention. According to the sectional view in 3 have the spring elements 20 two wings 21 and 22 on, which with corresponding projections 16 of the mounting auxiliary element 15 can lock. The mounting auxiliary element 15 So on the one hand on the shuttering 110 attached and on the other hand releasably with the rail 1 get connected.

In this in 3 and 4 configuration is then poured the concrete floor, leaving the rail 1 is enclosed by the concrete. The arrangement or design of the rail 15 on the one hand and the spring elements 20 On the other hand, it is such that the mounting rail with its bottom flush with the casing 101 is applied. Further, since it is also preferably provided that the ends are sealingly closed, for example, provided with a blind cover, it is ensured in this way that no concrete in the interior of the rail 1 penetrates. On at least one of the blind cover could also be added also a cable conduit, over which the supply of the electrical power supply or the cable for signal transmission takes place in a simple manner.

After the concrete material has hardened enough to form the ceiling, then the shuttering 101 be removed again. This is automatically the locking between the mounting auxiliary element 15 and the spring elements 20 solved. Due to the at the bottom side 3 the mounting rail 1 formed protrusions ensures that the mounting rail 1 in the concrete ceiling 100 remains anchored. After removing the spring elements 20 then can the busbar 10 be attached, so that ultimately the in 5 shown arrangement results.

The method according to the invention just described is characterized in that the mounting rail 1 in a very simple but reliable way in the concrete ceiling 100 can be introduced. At the same time, it is ensured that the mounting rail 1 flush with the underside of the ceiling without special measures being required. Finally, there is a further advantage in that the auxiliary assembly element can not be damaged during the implementation of the method and accordingly used repeatedly.

A second variant of the method according to the invention will be described below with reference to 6 to 13 be explained. In this case, the method is to an installation box, which generally with the reference numeral 30 is provided to introduce into a concrete wall. The tin 30 Can be used here for later assembly of switch units for the operation of lights and / or air conditioning units. Furthermore, of course, connection devices for power supply or for data transmission could be installed.

The tin 30 has a substantially cylindrical housing 31 on, at the front of an essay 32 is arranged. This serves to hold a Eingießmontageteils, which in 7c represented and with the reference numeral 40 is provided.

The pouring assembly part 40 is made of two sheet metal parts 41 and 42 formed, each as individual parts in the 7a and 7b are shown and each other to the Eingießmontageteil 40 be welded. Both sheet metal parts 41 and 42 are preferably made of 0.8 mm stainless steel and each have a central opening 43 respectively. 44 on which then ultimately an access to the interior of the installation box 30 is obtained. Further, in both sheet metal parts respectively on two opposite sides to the upper side bent wall portions 45 . 46 formed, so that - after the second sheet metal part 42 and 90 ° twisted with the first sheet metal part 41 has been welded - a flat cup-shaped arrangement is achieved with a square basic shape having a through hole in the bottom surface. The first sheet metal part 41 here has upstanding tabs on the two remaining longitudinal sides 47 on, which bearing surfaces for the second sheet metal part 42 form. In the peripheral region of the passage openings 43 respectively. 44 Furthermore, corresponding holes are provided. Ultimately, therefore, results after welding the two parts already mentioned and in 7c illustrated arrangement.

The Eingießmontageteil formed in this way 40 then with the installation box 30 bolted, taking the appropriate screws 34 in at the front of the essay 32 trained holes 33 intervention.

The resulting assembly consisting of installation box 30 and pouring assembly part 40 should now be placed in a concrete wall, in such a way that the leading edges of Eingießmontageteils 40 flush with the surface of the wall. The pouring assembly part 40 can then be used for receiving a corresponding cover eg. For a switch unit.

The introduction of the assembly is again according to the invention by means of a mounting auxiliary element, which in 9 represented and as so-called. Centering plate 50 is trained. It is an approximately square sheet metal part, which as well as the mounting auxiliary element 15 can be connected on the one hand with a casing to form a concrete wall and on the other hand with the assembly to be arranged in the concrete wall. The fastening of the centering plate 50 on a formwork via arcuate recesses 51 through the screws 59 can be performed, which are bolted to the (not shown) formwork. The arched shape of the recesses 51 allows a slight twisting of the weight plate 50 so that this can be aligned in a simple manner in the desired orientation.

The attachment of the centering plate 50 on the module consisting of the installation box 30 and the pouring assembly part 40 then takes place by tabs formed on the side walls 52 , which is a slipping of the assembly or Eingießmontageteils 40 on the centering plate 50 enable. There is a slight catch between the centering plate 50 and the pouring assembly part 40 instead, which ensures a sufficient support. The arrangement obtained in this case is in the 10 to 13 shown in different views, including the screws 59 for screwing on the centering plate 50 are shown on the shuttering. The assembly of the assembly on the Zentnerblech 50 Of course, this is done only after tightening the weight plate 50 at the screw connection.

A supplementary attachment of the assembly can also be carried out in that in the cylindrical attachment 32 the installation box 30 a circular insert 35 is trained. This has a hole in the center 36 on, over which another screw can be inserted and screwed to the casing. Also, the introduction of a nail would be conceivable, so that an additional attachment is obtained. The use 35 is over an annular groove 37 with the essay 32 connected, this groove 37 forms a predetermined breaking point. As will be explained later, then the use accordingly 35 automatically removed when removing the shuttering of the concrete wall. After the additional fastening by means of the screw or the nail is then the back of the box 30 with a lid 37 locked.

The assembly attached in this way to the casing is then encapsulated with concrete as in the first embodiment. After this has cured sufficiently, then the casing is removed, on the one hand, the locking between centering 50 and pouring assembly part 40 is solved. At the same time due to the breaking point of the use 35 in a can 30 removed, so that it is now accessible from the front of the wall through a circular opening. The tin 30 and the Eingießmontageteil 40 are now fixed by the concrete, so that the screw can be solved between the two elements and the switch or connection unit can be installed.

Again, there is the advantage that the installation box 30 in a simple way with the help of the centering plate 50 aligned in a desired manner can be arranged sunk in a concrete wall, wherein the Zentnerblech 50 is reusable. Further, in turn, the front end portion of the Eingießmontageteils closes 40 flush with the wall. Accordingly, as in the first exemplary embodiment, no free spaces remain between the wall and the hollow body to be introduced, for which reason the invention Especially method brings special advantages when the wall should not be plastered additionally. This therefore leads to decisive advantages, especially in exposed concrete applications, since now for the first time a possibility is offered to arrange such bodies in a simple but clean manner within the wall or ceiling.
