Abstract

The shuttering comprises mould tube heated for purpose of peripheral widening permitting withdrawal after concrete has set. Between the expanding mould tube (1) and a rigid outer covering (3,4,5,7,8) a fixed connection is produced and on one side of the mould tube several holding angles (2) are fixed, the arms of which standing away from the mould tube displaceably overlap with the arms or the flange of a cover plate (3) fixed to the covering. In order to protect against damage the mould tube, the electrical heating cable (9) and the insulation (10), a covering is provided, preferably of steel, comprising four sided tube frames at the top and at the bottom (4), four sided tubes as connection of the tube frames (7), covering plates (8), cover plates at the top and the bottom (3), fixed with rivets (5) to the tube frames.

Description

Die Erfindung betrifft eine Schalungsvorrichtung gemäß dem Oberbegriff des Anspruch 1.The invention relates to a formwork device according to the Preamble of claim 1.

Eine Schalungsvorrichtung zum Herstellen von prismatischen Bauteilen aus Stahlbeton, insbesondere runde Säulen und Stützen, bei welchen zum Zwecke der Umfangserweiterung des Schalungsrohres dasselbe erwärmt wird, um es so nach dem Abbinden des Beton leichter nach oben abziehen zu können, ist bekannt, vgl. die Druckschriften DE 33 40 810 C2 und DE 44 28 125 C1.A formwork device for making prismatic components Reinforced concrete, in particular round columns and supports, for which For the purpose of expanding the formwork tube, the same is heated to make it easier to pull it up after the concrete has set is known to be able, cf. the publications DE 33 40 810 C2 and DE 44 28 125 C1.

Der Nachteil der Vorrichtung besteht darin, daß einerseits um eine Aus­ weitung des Schalungsrohres durch Erwärmung erreichen zu können, dieses aus einem Material mit sehr hohem Ausdehnungskoeffizient, z. B. Kunststoff bestehen muß. Außerdem muß über den Heizelementen eine Isolierung angebracht sein, da sonst die Wärme in die falsche Richtung abfließt und das Rohr nicht gleichmäßig erwärmt wird. Andererseits muß die äußere Ver­ kleidung um den Ansprüchen und der Belastung auf den Baustellen gerecht zu werden und die beschädigungsempfindlichen Teile, Heizelemente und Isolierung zu schützen, aus formstabilem Material, z. B. Stahl bestehen. Stahl hat aber einen wesentlich geringeren Ausdehnungskoeffizient wie Kunststoff. Um die Schalungsvorrichtung kostengünstig zu gestalten, muß sie so ausgelegt sein, daß eine vielfache Verwendung gewährleistet ist. Aus diesem Grunde muß das innere Schalungsrohr mit der äußeren Verkleidung ein feste Verbindung haben, ohne daß die Ausdehnung des Schalungsrohres behindert wird. Denn unabhängig, ob die Schalung nach dem Abbinden des Beton am Schalungsrohr direkt nach oben abgezogen wird, oder ob dies an der Außenverkleidung geschieht, beide Teile müssen unlöslich miteinander verbunden sein. Das Ausdehnungsproblem zu lösen, in dem die äußere Verkleidung mitbeheizt wird, ist aus beschriebenem Grunde nicht möglich.The disadvantage of the device is that on the one hand to an off expansion of the formwork tube to be able to achieve this made of a material with a very high coefficient of expansion, e.g. B. plastic must exist. Insulation must also be placed over the heating elements appropriate, otherwise the heat will flow in the wrong direction and the pipe is not heated evenly. On the other hand, the external ver clothing to meet the demands and strain on the construction sites to become and the damage-sensitive parts, heating elements and To protect insulation from dimensionally stable material, e.g. B. steel. stole but has a much lower expansion coefficient than plastic. In order to make the formwork device inexpensive, it must be so be designed so that multiple use is guaranteed. For this Basically, the inner formwork tube with the outer cladding must be solid Have connection without the expansion of the formwork tube is hindered. Because regardless of whether the formwork after setting the Concrete is pulled straight up on the formwork tube, or whether this is on the outer cladding happens, both parts must be insoluble with each other be connected. To solve the expansion problem in which the outer For the reason described, cladding is also heated.

Die Aufgabe der Erfindung besteht darin, bei thermisch veränderbaren Schalungen eine feste Verbindung zwischen dem sich im Durchmesser und der Länge veränderbaren Schalungsrohr und der starren Außenverkleidung zu schaffen, ohne daß dabei die Ausdehnungsmöglichkeit des Schalungsrohres behindert wird.The object of the invention is in the case of thermally changeable Formwork a firm connection between the ones in diameter and the length of the formwork tube and the rigid outer cladding to create without the possibility of expansion of the Formwork tube is hindered.

Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 genannten Merkmale gelöst.This object is achieved by those mentioned in claim 1 Features resolved.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Subclaims.

Ausführungsbeispiele nach der Erfindung sind in den Zeichnungen dargestellt.Embodiments according to the invention are in the drawings shown.

Es zeigen:Show it:

Fig. 2 einen Längsschnitt an der Oberseite, Fig. 2 is a longitudinal section at the top,

Um das Schalungsrohr (1), die Elektroheizkabel (9) und die Isolierung (10) vor Beschädigung zu schützen, erhalten sie eine Verkleidung, vorzugsweise aus Stahl, bestehend aus Vierkantrohr-Rahmen oben und unten (4), Vier­ kantrohren als Verbindung der Rohrrahmen (7), Verkleidungsplatten (8), Abdeckplatten oben und unten (3), welche mit Nieten (5) an den Rohr-Rahmen befestigt werden. Dargestellt ist die Verkleidung in quadratischer Form. Sie kann aber auch rund oder andersförmig ausgeführt sein. Damit zwischen dem Schalungsrohr (1) und der Außenverkleidung (3, 4, 5, 7 und 8) eine feste Verbindung besteht, wird an einer Seite, vorzugsweise unten, an das Schalungsrohr (1) mehrere, vorzugsweise 4 Stück Haltewinkel (2) mit Schrauben (6) befestigt. In order to protect the formwork tube ( 1 ), the electric heating cables ( 9 ) and the insulation ( 10 ) from damage, they receive a cladding, preferably made of steel, consisting of a square tube frame at the top and bottom ( 4 ), four square tubes as a connection of the tube frame ( 7 ), cladding panels ( 8 ), cover panels at the top and bottom ( 3 ), which are fastened to the tube frame with rivets ( 5 ). The cladding is shown in a square shape. But it can also be round or different. So that there is a firm connection between the formwork tube ( 1 ) and the outer cladding ( 3 , 4 , 5 , 7 and 8 ), several, preferably 4, brackets ( 2 ) are attached to the formwork tube ( 1 ) on one side, preferably below Screws ( 6 ) attached.

Die Ausdehnung des Schalungsrohres (1) im Umfang und somit im Durch­ messer des Rohres und der Veränderung gegenüber der Außenverkleidung wir dadurch ermöglicht, daß zwischen dem Rechteckrohr-Rahmen (4) und der Abdeckplatte (3) so viel Platz gelassen wird, daß der Haltewinkel (2) dazwischen liegt. Der untere Schenkel des Haltewinkels (2) ist nur so lang, daß genügend Ausdehnungsmöglichkeit bestehen bleibt. Das gleiche trifft für den Lochdurchmesser der Abdeckplatte (3) zu.The expansion of the formwork tube ( 1 ) in the circumference and thus in the diameter of the tube and the change compared to the outer cladding is made possible by leaving enough space between the rectangular tube frame ( 4 ) and the cover plate ( 3 ) that the bracket ( 2 ) lies in between. The lower leg of the bracket ( 2 ) is only so long that there is enough room for expansion. The same applies to the hole diameter of the cover plate ( 3 ).

Die andere, vorzugsweise obere Seite des Schalungsrohres (1) wird nur lose in ein Ausgleichsprofil (11), welches aus einem dehnfähigen Material, vor­ zugsweise Hartgummi besteht und in die Abdeckplatte (3) geklemmt ist, gelegt. Dadurch kann sich das Schalungsrohr (1) sowohl im Durchmesser, als auch in der Länge ungehindert ausdehnen.The other, preferably upper side of the formwork tube ( 1 ) is only loosely placed in a compensation profile ( 11 ), which consists of a stretchable material, preferably hard rubber and is clamped in the cover plate ( 3 ). This allows the formwork tube ( 1 ) to expand freely both in diameter and in length.
