Abstract

This invention relates to shuttering or sheathing elements of hard expanded plastics material for construction of buildings by the concrete casing method, of the kind comprising two mutually parallel panels or slabs having a tongued and grooved form at their edges and webs interconnecting the panels. According to the invention the panel forming the outer casing is considerably thicker than the panel of the element forming the inner casing.

Description

Die Erfindung betrifft ein Schalungselement aus geschäumtem Hartkunststoff für die Mantelbetonbauweise, bestehend aus zwei parallel zueinander angeordneten Platten mit Nut-Feder-Ausbildung an ihren Rändern und aus die Platten miteinander verbindenden Stegen.The invention relates to a formwork element made of foamed hard plastic for the shell-concrete construction, consisting of two parallel plates with tongue and groove design on their edges and of webs connecting the plates together.

In der DE-PS 1 784 573 ist ein Schalungselement gemäß der vorstehend genannten Art beschrieben. Bei diesem Element sind beide , die jeweiligen späteren Isoliermäntel bildenden Platten gleich dick bemessen. Das führt zu dem Nachteil, daß , da die Dicke der Platten zur Erzielung einer sehr guten Wärmedämmung ziemlich groß ist, die Dampfdurchlaßzeit durch die raumseitige, den Innenmantel bildende Platte beträchtlich lang ist. Dadurch vollzieht sich der Feuchtigkeitsaustausch zwischen Gebäudewand und Raum relativ träge, was sich ungünstig auf das Raumklima auswirkt. Ferner hat sich herausgestellt, daß die Verankerungsmöglichkeit von Befestigungsmitteln, z.B. Dübeln, verbesserungsbedürftig ist, um mit einfachen Dübeln auch schwere Gegenstände an den Wänden befestigen zu können.DE-PS 1 784 573 describes a formwork element according to the type mentioned above. In this element, both plates, which later form the respective insulating sheaths, have the same thickness. This leads to the disadvantage that since the thickness of the panels is quite large in order to achieve very good thermal insulation, the steam passage time through the space-side, which forms the inner jacket Plate is considerably long. As a result, the moisture exchange between the building wall and the room is relatively slow, which has an unfavorable effect on the room climate. It has also been found that the possibility of anchoring fasteners, for example dowels, is in need of improvement in order to be able to fasten even heavy objects to the walls with simple dowels.

Die Aufgabe der Erfindung besteht in der Verbesserung eines Schalungselementes gemäß der einleitend angeführten Art in der Hinsicht, daß bei Gewährleistung einer ausgezeichneten Wärmedämmung raumseitig eine relativ schnelle Dampfdurchlässigkeit, eine bessere Nutzung des eingefüllten Betons als Wärmespeicher sowie eine sichere Verankerung von Befestigungsmitteln erzielt wird.The object of the invention is to improve a formwork element according to the type mentioned in the respect that a relatively fast vapor permeability, better use of the filled concrete as a heat accumulator and a safe anchoring of fasteners is achieved on the room side while ensuring excellent thermal insulation.

Die Lösung dieser Aufgabe besteht darin, daß die den Außenmantel bildende Platte des Schalungselementes dicker ist als die den Innenmantel bildende Platte des Elementes.The solution to this problem is that the plate of the formwork element forming the outer jacket is thicker than the plate of the element forming the inner jacket.

Unter Beibehaltung einer sehr guten Wärmedämmung ist durch die dünnere,später raumseitig befindliche Platte gleichzeitig die Dampfdurchlässigkeit von der Raumseite her verbessert, so daß Feuchtigkeit aus dem Raum relativ schnell in den Betonkern, der sich in den zusammengesteckten und mit Beton ausgefüllten Schalungselementen befindet, eindringen kann, so daß sich der feuchtigkeitsbedingte Anteil des Raumklimas schnell regelt. Andererseits kann der Betonkern auch besser als Wärmespeicher genutzt werden, da er schneller von der Raumwärme erreicht wird und umgekehrt relativ mehr gespeicherte Wärme in den Raum zurückgeben kann. Wegen der relativ dünnen , den Innenmantel bzw. die Rauminnenseite bildende Platte dringen längere Befestigungsmittel, insbesondere Dübel, ausreichend tief in den Beton ein und geben dadurch mehr Halt, so daß auch. schwere Gegenstände an einer solchen Wand befestigt werden können.While maintaining very good thermal insulation, the thinner, later on the room-side panel also improves the vapor permeability from the room side, so that moisture from the room can penetrate relatively quickly into the concrete core, which is in the assembled and filled with concrete formwork elements , so that the moisture-related part of the indoor climate regulates itself quickly. On the other hand, the concrete core can also be used better as a heat store, since it is reached more quickly by the room heat and, conversely, can return relatively more stored heat into the room. Because of the relatively thin plate forming the inner jacket or the inside of the room, longer fastening means, in particular dowels, penetrate sufficiently deep into the concrete and give more hold, so that also. heavy objects can be attached to such a wall.

Weiterbildende Merkmale bestehen bei Verwendung von Z-förmigen Stegen darin, daß die Bereiche wenigstens der dickeren Platte, die dem Mittelteil der Stege gegenüberliegen, ausgespart sind, daß die Anschlußteile der Stege mit dem Plattenrand und dem Ende der Stegmittelteile bündig abschließen und daß der innere Horizontalbereich der Anschlußteile im Profil gekrümmt ausgebildet ist.Further features when using Z-shaped webs are that the areas of at least the thicker plate, which lie opposite the central part of the webs, are recessed, that the connecting parts of the webs are flush with the plate edge and the end of the web central parts, and that the inner horizontal area the connecting parts are curved in profile.

Ein derartiges Schalungsbauelement weist eine gesteigerte Bruchfestigkeit auf, und zwar bei Verwendung von sowohl Stampfbeton als auch plastischem Beton. Im ersten Fall entstehen beim Stampfen keine Lunkerstellen bzw. Hohlstellen mehr direkt unter den nach unten gerichteten Horizontalflächen der Anschlußteile der Stege, da das Stampfwerkzeug diese Stellen bequem erreichen bzw. sicher Beton in Richtung dieser Stellen bringen kann. An diesen Stellen kann auch bei Verfüllung von plastischem Beton keine Entmischung mehr stattfinden, da auch gröbere Kiesanteile des Betons zu diesen Stellen gelangen können. Außerdem wird eine Festigkeitssteigerung auch dadurch erzielt, daß in wenigstens einige der Zwischenräume zwischen Platte und Steg mehr Beton eingebracht werden kann, und zwar aufgrund der an der betreffenden Platte vorgesehenen Aussparungen, so daß sich ein dickerer Betonsteg ausbildet.Such a formwork component has an increased breaking strength when using both stamped concrete and plastic concrete. In the first case, holes or voids no longer arise during tamping directly under the downward horizontal surfaces of the connecting parts of the webs, since the ramming tool can easily reach these points or can safely bring concrete in the direction of these points. At these points, even when plastic concrete is backfilled, segregation can no longer take place, since coarser gravel parts of the concrete can reach these points. In addition, an increase in strength is also achieved by the fact that more concrete can be introduced into at least some of the spaces between the plate and the web, due to the recesses provided on the plate in question, so that a thicker concrete web is formed.

Die Erfindung ist nachstehend anhand eines in der anliegenden Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:

  • Figur 1 eine Endansicht auf das Ausführungsbeispiel,
  • Figur 2 eine Aufsicht gemäß dem Pfeil A in Figur 1,
  • Figur 3 eine teilweise Schnittdarstellung gemäß der Linie III - III in Figur 2.
The invention is explained below with reference to an embodiment shown in the accompanying drawing. Show it:
  • FIG. 1 shows an end view of the exemplary embodiment,
  • FIG. 2 shows a top view according to arrow A in FIG. 1,
  • FIG. 3 shows a partial sectional illustration along the line III-III in FIG. 2.

Nach den Figuren 1 und 2 besteht das für die Mantelbetonbauweise beim Gebäudebau verwendete Schalungselement 1 aus zwei zueinander parallelen Kunststoffplatten 2 und 3 aus geschäumtem Hartkunststoff, z.B. Styropor.An ihren Rändern bzw. Schmalseiten sind die Platten in üblicher Weise mit einer aus Nut 4 und Feder 5 bestehenden Ausbildung versehen. Eine der Platten ist dicker ausgebildet als die andere und wird zur Bildung eines stark wärmedämmenden Außenmantels der Gebäudeaußenwände verwendet. Die dickere Platte 2 kann erheblich dicker sein als die dünnere Platte 3, z.B. dreimal so dick.Im allgemeinen wird die Dicke der Platte 2 in der Größenordnung von 4cm bis 20cm liegen und vorzugsweise etwa 12cm betragen; die Dicke der dünneren Platte 3 wird in der Größenordnung von 2cm bis 8cm liegen und vorzugsweise etwa 5cm betragen.According to FIGS. 1 and 2, the formwork element 1 used for the shell-concrete construction method in building construction consists of two mutually parallel plastic panels 2 and 3 made of foamed hard plastic, e.g. Styrofoam. At their edges or narrow sides, the plates are provided in the usual way with a training consisting of groove 4 and tongue 5. One of the panels is thicker than the other and is used to form a highly heat-insulating outer shell of the building's outer walls. The thicker plate 2 can be considerably thicker than the thinner plate 3, e.g. three times as thick. In general, the thickness of plate 2 will be on the order of 4cm to 20cm and preferably about 12cm; the thickness of the thinner plate 3 will be of the order of 2 cm to 8 cm and preferably about 5 cm.

Ferner ist die Nut-Feder-Ausbildung 4,5 der dickeren Platte 2 im Vergleich zu derjenigen der dünneren Platte 3 ebenfalls breiter ausgebildet. Diese stärkere Dimensionierung der einen Nut-Feder-Ausbildung trägt bei entsprechend engem Paßmaß zu einem festeren Zusammenhalt der zusammengefügten Schalungselemente bei und ist ferner weniger bruchanfällig bei Transport und Handhabung der Elemente.Furthermore, the tongue and groove formation 4, 5 of the thicker plate 2 is also wider than that of the thinner plate 3. This stronger dimensioning of a tongue and groove design, with a correspondingly tight fit, contributes to a firmer cohesion of the assembled formwork elements and is also less prone to breakage during transport and handling of the elements.

Die Platten 2,3 sind vorzugsweise durch Z-förmige Stege 6 und 7 miteinander verbunden, wie aus Figur 1 ersichtlich ist. Der Mittelteil 6a,7a der Stege reicht beidendig bis zu den Rändern bzw. Schmalseiten der Platten 2,3 heran und kann an einem Ende mit einem Zapfen 8 und am anderen Ende mit einer entsprechenden Ausnehmung 9 versehen sein. Weiterhin sind vorteilhaft die Bereiche 6b bzw. 7b der Stege, die den Platten unmittelbar gegenüberliegen, gerundet oder polygonal ausgebildet oder auf andere Weise gekrümmt geformt (Figur 2). Die Anschlußteile 6c bzw. 7c der Stege 6 und 7 erstrecken sich etwa über die halbe Höhe der Platten 2,3 und schließen an ihrem einen Ende bündig und ebenflächig mit dem Plattenrand und dem Ende der Stegmittelteile 6a,7a ab. Andererseits ist ihr innerer Horizontalbereich 6d bzw. 7d im Profil gerundet oder auf andere Weise gekrümmt ausgebildet, wie Figur 3 deutlich zeigt.The plates 2, 3 are preferably connected to one another by Z-shaped webs 6 and 7, as can be seen in FIG. 1. The middle part 6a, 7a of the webs extends on both ends up to the edges or narrow sides of the plates 2, 3 and can be provided at one end with a pin 8 and at the other end with a corresponding recess 9. Furthermore, the regions 6b and 7b of the webs which are directly opposite the plates are advantageously rounded, polygonal or curved in some other way (FIG. 2). The connecting parts 6c and 7c of the webs 6 and 7 extend approximately over half the height of the plates 2, 3 and close at one end flush and even with the plates edge and the end of the web middle parts 6a, 7a. On the other hand, their inner horizontal region 6d or 7d is rounded in profile or curved in another way, as FIG. 3 clearly shows.

Wenigstens die dickere Platte 2 des Elementes 1 weist Aussparungen 1o auf, die den Bereich 6b bzw. 7b der Stege 6 und 7 gegenüberliegen und ermöglichen, daß in den hiervon begrenzten Zwischenräumen später dickere Betonverbindungsstege entstehen.At least the thicker plate 2 of the element 1 has cutouts 10, which lie opposite the regions 6b and 7b of the webs 6 and 7 and enable thicker concrete connecting webs to be created later in the spaces between them.

Ferner können die Stege 6,7 Vorkehrungen aufweisen, mit deren Hilfe übliche Bewehrungseisen festgelegt werden. Wie Figur 2 zeigt, können in den Übergangsbereichen der Anschlußteile 6c, 7c zur dünneren Platte 3 Profilierungen 11 integriert sein, die Bewehrungseisen 12 aufnehmen oder festlegen.Furthermore, the webs 6, 7 can have precautions with the aid of which conventional reinforcing bars are fixed. As FIG. 2 shows, in the transition areas of the connecting parts 6c, 7c to the thinner plate 3, profiles 11 can be integrated, which receive or fix reinforcing bars 12.

Wie aus den Figuren 1 und 2,-insbesondere aus Figur 2, zu entnehmen ist, sind die Z-förmigen Stege 6, 7 des Elementes 1 spiegelbildlich zueinander verdreht angeordnet. Dies ergibt später einen mäanderförmigen Verlauf des eingefüllten Betons, was insbesondere eine Erhöhung der Gestaltfestigkeit des abgebundenen Betons bedeutet.As can be seen from FIGS. 1 and 2, in particular from FIG. 2, the Z-shaped webs 6, 7 of the element 1 are arranged in a mirror-inverted manner relative to one another. This later results in a meandering course of the filled concrete, which means in particular an increase in the structural strength of the set concrete.

In einer vorteilhaften Weiterbildung besteht ein Merkmal darin, daß vorzugsweise die den Außenmantel bildende, dickere Platte 2 mit senkrechten Rillen 13 versehen ist. Diese Rillen sorgen für eine verbesserte Haftung einer Putzschicht (nicht gezeigt) auf der Außenfläche der Platte 2. Alternativ oder zusätzlich können auch waagerechte Rillen 14 vorgesehen sein. Die Rillen sind etwa 2-3mm breit und 2mm tief.In an advantageous further development there is a feature that preferably the thicker plate 2 forming the outer jacket is provided with vertical grooves 13. These grooves ensure improved adhesion of a plaster layer (not shown) on the outer surface of the plate 2. Alternatively or additionally, horizontal grooves 14 can also be provided. The grooves are about 2-3mm wide and 2mm deep.

Vorteilhaft wird das beschriebene Schalungselement in der Länge im Rastermaß gefertigt, z.B. in den Maßen 12,5cm, 25cm, 50cm und 100cm. Die Höhe kann z.B. 33,3 cm und die Breite z.B. 36cm betragen.The formwork element described is advantageously produced in length in grid dimensions, for example in the dimensions 12.5 cm, 25cm, 50cm and 100cm. The height can be, for example, 33.3 cm and the width, for example, 36 cm.
