Abstract

A device for producing cavities for installations, in which, with the omission of plastic tubes, a rubber hose which is closed at one side, has a helical pressure spring in its interior and a connection with a shut-off valve which can be switched over is provided. The rubber hose is provided with superatmospheric pressure before concreting, but can be switched over to subatmospheric pressure after concreting and can be removed without difficulty, leaving behind a smooth wall.

Description

Vorrichtung zum Eerstellen vonDevice for creating

Freiraumen für Installationen Andreas Holterhus Paul Couwenbergs Hauptstraße 21 Scheibenbergstr. 17 D - 4441 Spelle D-7500 Karlsruhe 21 Die Erfindung ist eine Zusatzanmeldung zur Patentanmeldung P 32 40 166.3 die eine Vorrichtung zum Herstellen von Freiräumen für Installationen betrifft, mit der nachtäglich Kabel, biegsame Rohre oder dergleichen eingeführt werden können.Space for installations Andreas Holterhus Paul Couwenbergs Hauptstrasse 21 Scheibenbergstrasse 17 D - 4441 Spelle D-7500 Karlsruhe 21 The invention is a Additional application to the patent application P 32 40 166.3 the one device for manufacturing concerns of free spaces for installations, with the after-hours cables, flexible Pipes or the like can be introduced.

Sie stellt eine Weiterentwicklung des Hauptanspruchs o.g.It represents a further development of the main claim o.g.

Patentanmeldung dar.Patent application.

Dennoch ist eine Aufgabenstellung gegeben, die darin besteht, daß der Schlauch vor dem Unterdrucksetzen tritt-und knickfest sein sollte, auch beim drucklosmachen sollte sich der Schlauch besser lösen.Nevertheless, there is a task that consists in that The hose should be kicked and kink-proof before pressurization, even when Depressurise the hose, it should be better to loosen it.

Die gestellte Aufgabe wird dadurch gelöst, daß innerhalb des Schlauches eine, mit einem um 1/20 bis 1/4 kleineren AuP.endurchmesser als der Innendurchmesser des Schlauches versehene Schraubendruckfeder angeordnet ist.The problem posed is achieved in that within the hose one with an outer diameter of 1/20 to 1/4 smaller than the inner diameter the hose provided helical compression spring is arranged.

Der zweite Teil der gestellten Aufgabe wird durch den Unteranspruch gelöst.The second part of the task is covered by the dependent claim solved.

Die Erfindung wird nun anhand der schematisch dargestellten Zeichnung näher erläutert.The invention will now be explained with reference to the schematically illustrated drawing explained in more detail.

Es zeigt die Fig.1 einen drucklosen Schlauch im Schnitt, und die Fig.2 diesen Schlauch mit Vakuum beaufschlagt.FIG. 1 shows a section of a pressureless hose, and FIG. 2 applied a vacuum to this hose.

Die im Hauptpatent angeführten Bezeichnungen wurden weitgehend eingehalten.The designations listed in the main patent were largely adhered to.

So ist auch hier ein Schlauch 1 auf seinem einen Ende 2 medlumdicht verschlossen und besitzt auf dessen anderem Ende 3 einen Anschluß 4 für Druck- oder terdruckmedium.Here, too, a tube 1 is medlum-tight on its one end 2 closed and has on the other end 3 a connection 4 for pressure or pressure medium.

Der Anschluß 4 sitzt an einem umschaltbaren Rbsnerrventil 5.The connection 4 is located on a switchable Rbsnerrventil 5.

Die Pfeile + und - sollen andeuten, daß die Eingänge des Absperrventils 5 mit Überdruck, bezw., mit Unterdruck beaufschlagt werden können. Neu ist auch eine Schraubendruckfeder 6,die im innern des Schlauches 1 ungeordnet ist. Die Schraubendruckfeder 6 ist nicht so ausgelegt, d der Schlauch 1 gestreckt wird, sondern nur zum Festanliegen der beiden Enden 2 und 3. Außerdem soll mit dem Begriff Schraubendruckfeder 6 nur darauf hingewiesen werden, daß sie eine grobe Ganghöhe besitzt.The arrows + and - should indicate that the inputs of the shut-off valve 5 with overpressure or., Can be acted upon with negative pressure. Is also new a helical compression spring 6 which is disordered inside the hose 1. The helical compression spring 6 is not designed in such a way that the hose 1 is stretched, but only so that it fits tightly of the two ends 2 and 3. In addition, the term helical compression spring 6 is only intended to be advised that they are a possesses a coarse pitch.

In der Fig.2 ist Schlauch 1 mit allen seinen Teilen mit den gleichen Zahlen versehen. Nur ist hier das Absperrventil 5 mit dem Vakuumeinlaß verbunden und der Schlauch 1 wird - wie hier dargestellt - bis auf seine Schraubendruckfeder 6 und etwas mehr, zusammengezogen. Was ein garantiertes lösen des Schlauches 1 zur Folge hat.In FIG. 2, hose 1 is the same with all of its parts Numbers provided. Only here the shut-off valve 5 is connected to the vacuum inlet and the hose 1 is - as shown here - except for its helical compression spring 6 and a little more, pulled together. What a guaranteed loosening of the tube 1 to Consequence.
