Junction box for

electrical cables in a wall to the reinforced concrete cd. like

In the manufacture of reinforced concrete walls and in particular in the production of convertible agents in hairdryers in a factory or when pouring at the construction site, there is a hot flexibility, Pipes for electrical lines and in particular connection lines to attach, with an opening in the face of the wall the purpose is »switches» wall contact sockets, lamp holders and the like, attach and connect as follows, unless it is balanced or in any case economically unreasonable to insert recessed lines and connector sockets into the concrete later, while pipes installed on the surface of the walls are only acceptable in industrial rooms and not in residential rooms are·.

Such a junction box is known to have its opening to be attached to the inner surface of a housing or a formwork wall and to remove the covered area GuiMi to be fixed by a bolt, screw or a Sagel is screwed into the formwork wall, or ia A steel shuttering wall is covered with the help of an oil magnet fasten, after which the can is pressed onto the cap and auletiet the Eabel pipes or flexible pipes bit of the can

be bimden. In known arrangements, this is achieved by breaking holes in the doee into which special sleeves made of Gunei or flexible plastic are stuffed are »with the sleeves old inner ribs, which old koaaen the outer ribs of the pipe for the lines in contact, after which such a tube is pushed into each tube and the tube is finally attached to the tube with the help of a spring band is advertised.

They known arrangements require a substantial number of ropes while attaching these parts to a housing or a stupid sight. The view concerns a junction box «ad suitable parts for their construction, which is also possible for unskilled workers, lines fasten eu of this type quickly and effectively, whereby of a small number of parts as possible use which are produced in a very economical manner can.

Formwork wall breaks in the transverse or longitudinal direction, so that preferred "Unless a pin is used" which consists of "sw # i parts ■ with friction fit into each other ·

This enables a quick and effective attachment of a junction box to a formwork with the help of very simple ropes »And can be achieved, for which no special factory eye is necessary and what can be done by an unskilled worker

When pouring the concrete, it has upright formwork walls it has been found that it is advisable to find a place between the To attach the connecting box and the opposite formwork wall, which are the reasons for the invention Pipe od for the line Support plate runs and on the other hand is fixed in a suitable recess in the clamping means, see the support plate support against the opposite formwork wall. Instead of A second junction box can advantageously be used in connection with a stud plate, if the same as the one mentioned above Line can be inserted into a nozzle in the bottom of the can, while the wicked one in the same way as the first can can be attached in which · lalle the line in the Chuck is fitted. When the chucks old a VersealuBwand is provided, which can be durohstoflen, can Connection between the two sockets can be established.

Ia with a view to speeding up the very time-consuming attachment the conduits in known methods are geeäß of the invention Verblndungsdoeen old fixed nozzle used that ■ it is provided with a suitable Kleaaflaohe. With «Attach Conical nozzle surfaces can advantageously be used for smooth pipes into which the pipes are self-cleaving and water-

can be used tightly. Instead, a threaded resilient stub old of a clamping coupling which is screwed on and which is in the suitably ribbed flexible pipes for the lines fits, with the Stutsen voriugsvaise on the inside old of an XI « edge are provided, while they are sawn off on the outside Xante have · the age of an inner bevel of the Clamping coupling in contact koaat. You don't use Stutsen can be concluded by means of Ueaaetupeeln »while instead hat nuts can also be put on.

^: You're firing

Also applies to one or more junction boxes, ropes for the tight fastening of a box to a housing or a Formwork wall and flexible pipes that are sue forming a sighting with suitable openings for connection with such a socket are provided for the introduction of the lines into the socket, the hiring is marked by a loose and a central hole in its bottom, through a closure, which forms a tight attachment to the opening of the can and ait a central opening is provided by a dowel pin »which is to be fastened in or on a formwork wall, the pin being a Has a weakening point and has a thread at its free end is provided, and by a chuck that eitsrt on the thread. The weakening point is obtained in particular by that the dowel pin is formed from two parts which fit into one another by means of sufficient friction, while also or sudea part of the pin can be narrowed, which makes it easy for the pin to break into two ropes.

The pen is especially in the possession of its end, that at the Formwork wall is to be attached, old provided a somewhat conical outer surface on which the edge of the center hole of the Lock so that a sighting is formed.

The Spaanautter can also be seen with a recess - »into which one end of a support element fits, the adder, if necessary, at the level of the recess has a locking partition, the uppermost can be.

A junction box of this type also contains nozzles, with those in the manner indicated above the pipe for the Lines can be connected quickly and efficiently, with the nozzle, when not in use, by means of a plug or a cap nut can be closed.

A particular advantage of clamping in the position of the pipes, the old the Klemnj & ttern according to the invention is available, consists in the fact that the junction boxes can be connected to bit pipes and transported as a finished unit to the construction site where the concrete is poured, as far as a positive clamping effect avoids the risk of the pipes loosening. An advantage of the nozzle and nuts according to the invention Ib in comparison to known nozzles and nuts in watertight distribution boxes in that the attachment can be carried out more quickly and, moreover, that the attachment is better.

The invention is described in detail below with reference to the drawing in which Pig. 1 a section through a junction box attached to a formwork wall, and Pig. 2 a corresponding section through a similar junction box bit of a second box coupled to it, which is supported against a second formwork wall, demonstrate.

In Pig. 1 shows a part of a shuttering wall 1 made of metal, for example, which is part of a shuttering for the casting of convertibles aua is reinforced concrete. The formwork wall 1 is at

stinaten points at which junction boxes are connected to the Wandeleaent are to be attached, provided with blind thread holesa 2. If Scha lung walls aas Hols or the like. Are used, aetallieehe Oewindebuehsen old splashing can be used, the can be attached to this wall.

The first half 3 of a roll pin is screwed into the hole 2, that of a threaded part 4 "one" attached to it Collar 5, which has a Seohskantteil 6, and an ia essential shell end part 7 consists ... Bine wide HaMfte 8 of the pen is effective the first HSHfte 3 sasaaaen, whereby the sweite part over the greater part sylindriaeh 1st and on his one volume has a hexagon 9 and an entwinde 10 at its other end. Xn the sueret mentioned (towinde is a hole drilled, in which volume 7 of the first half 3 is more noticeable KleBBw. «Rkung fits. Half 8 of the pen can also be like this the drawing seems to be hollow, both halves of the pen exist preferably made of hard plastic, although in bestiaatea babble Metalletlfte may be preferred if s.B. Operations run at elevated temperatures.

One in the formwork wall 1 in the fastening junction box 1st sit 12 bonus. This box has a bottom 13 and one Hittellooh 14 »in which the white half 8 of the pen fits, Before the box is attached to wall 1, the opening is made A bridge 15 is closed off by a central opening 16 that fits on the central opening of the collar 5 of the first pin »halfto 3. The collar is generally shown as a precaution beveled so that a good sighting can be obtained *. Through this if the can on the side of the opening is watertight, while the cover 15 touches the walls of the can against the edge of the concrete poured into the formwork will.

Hachdea the halves 3 and 8, which are joined together, on the Wall 1 have been attached and the Doee in the catfish shown is pressed onto the pin, a chuck 17 is placed on it the thread 10 of the pin half 8 is screwed, whereby the can is clamped under force against the wall 1, daait the desired waterproof connection on the wall can be obtained. Pie Frictional force swieohen the two halves 3 and 8 of the pin is sufficient at the same time, including withstanding the clamping force su.

The box shown is also old in a number of Nozzles provided for the connection of pipes for the lines, with two execution forms at 18 and 19 are shown. Of the

Nozzle 18 is particularly suitable for connecting smooth pipes

20 stared, from which round its inner surface is somewhat conical is so that a flexible pipe old Kleaawerkung carried out can be and deageaäß results in a watertight seal. It is also possible to use a rectangular shaped socket instead of a conical one To use nozzles, with one in the rectangular nozzle conical coupling element is inserted. A follow-up procedure this type has the gate part that the cans can be attached very quickly.

if flexible and ribbed pipes are used »which are excellently suited for the purposes envisaged, as these can easily be laid between reinforcement bars conical nozzles are less suitable. In this case nozzles i »the fora shown at 19 are preferred. These Nozzles are provided with a thread 21 on the outside of the 5 and they further have a number of notches cut at a number of points including the periphery thereof are distributed as shown at 22, resulting in the formation of a number of resilient lips.

A protruding end edge 23 is also provided, which thickened towards the inside. A stub of this type can rest under the action of cedar on a ribbed rotor which is imprinted therein, and can also be clipped onto it while forming a sighting with the aid of a nut which is screwed onto the thread 21. The collar edge of the mare is also beveled on the outside, while the nut 24 has a corresponding inner earring 26. If the mother is determined sucked 19, Zueassenwirken the slanted Kurten 25 and 26 the thickened end edge 23 pressed firmly against the "and the Eöux # ö, ma d su leads, DSS, the tube is festgeklesst in this position, us a sighting form au. A socket of this kind is also suitable for smooth pipes in this position and can therefore be used practically on all sides.

When connection boxes of this type serve as a central box these usually contain a fairly large number from Stutsen who do not use lasers. Although it is possible to keep the mares off, usually by means of a partition that can be broken through, it is recommended that you that the Stutsen offer »remain and that only the unused Stutsen old from a Hessetöpsel are locked« which accelerates the follow-up work can be. Bs is also essential to lock hats off the StutscB su use.

After the concrete has been poured into the formwork and has set * the circuit & vand 1 can be removed. If the wall is sucked in a longitudinal direction from halves 3 and 8 of the pin, the connection between these two halves is broken. You half 3 can then be screwed out of the hole, while the other half 8 can be unscrewed from the nut Xl · You Moser remains in the concrete steoken. If, on the other hand, the wall is removed across the pegs, the narrowed part 7 of the first half 3 'will break in the same way as. proceeded beforehand. These pens are

• rather cheap, because after the application it was thrown away can. But let us also say that the two halves are leather Match each other, in which case care should be taken except that the force is sufficient.
