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 Nr. 1784573 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 vollziehtsich 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 No. 1784573 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 panel on the room side, which forms the inner jacket, is considerably long. This means that 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, eg. B. dowels, is in need of improvement in order to be able to fasten 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 introduction in that with ensuring excellent thermal insulation on the room side a relatively quick vapor permeability, better use of the filled concrete as a heat accumulator and secure anchoring of fasteners is achieved.

Die Lösung dieser Aufgabe besteht darin, dass die den Aussenmantel bildende Platte dicker ist als die den Innenmantel bildende Platte des Elementes und dass die den Aussenmantel bildende Platte eine breitere Nut-Feder-Ausbildung aufweist als die dünnere Platte.The solution to this problem is that the plate forming the outer jacket is thicker than the plate forming the inner jacket of the element and that the plate forming the outer jacket has a wider tongue and groove configuration than the thinner plate.

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 located in the formwork elements that are assembled and filled with concrete , 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 thereby give more hold, so that even heavy objects can be fastened 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 middle 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 middle 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, no holes or voids are created during tamping directly below 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:

  • Fig. 1 eine Endansicht auf das Ausführungsbeispiel,
  • Fig. 2 eine Aufsicht gemäss dem Pfeil 11 in Fig. 1, und
  • Fig. 3 eine teilweise Schnittdarstellung gemäss der Linie 111-111 in Fig. 2.
The invention is explained below with reference to an embodiment shown in the accompanying drawings. Show it:
  • 1 is an end view of the embodiment,
  • Fig. 2 is a plan according to the arrow 11 in Fig. 1, and
  • 3 is a partial sectional view along line 111-111 in FIG. 2.

Nach den Fig. 1 und 2 besteht das für die Mantelbetonbauweise beim Gebäudebau verwendete Schalungselement 1 aus zwei zueinander parallelen Kunststoffplatten 2 und 3 aus geschäumten 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 dikker ausgebildet als die andere und wird zur Bildung eines stark wärmedämmenden Aussenmantels der Gebäudeaussenwände verwendet. Die dickere Platte 2 kann erheblich dicker sein als dünnere Platte 3, z. B. dreimal so dick. Im allgemeinen wird die Dicke der Platte 2 in der Grössenordnung von 4 bis 20 cm liegen und vorzugsweise etwa 12 cm betragen; die Dicke der dünneren Platte 3 wird in der Grössenordnung von 2 bis 8 cm liegen und vorzugsweise etwa 5 cm betragen.According to FIGS. 1 and 2, the formwork element 1 used for the shell concrete construction in building construction consists of two mutually parallel plastic panels 2 and 3 made of foamed hard plastic, for. B. 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 thinner plate 3, e.g. B. three times as thick. In general, the thickness of the plate 2 will be on the order of 4 to 20 cm and preferably about 12 cm; the thickness of the thinner plate 3 will be of the order of 2 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 narrow 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 Fig. 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 (Fig. 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 Fig. 3 deutlich zeigt.The plates 2, 3 are preferably connected to one another by Z-shaped webs 6 and 7, as can be seen from 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 on 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 another way (FIG. 2). The connection parts 6c and 7c of the webs 6 and 7 extend approximately over half the height of the plates 2, 3 and are flush at one end and flush with the plate edge and the end of the web center 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 10 auf, die dem 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 area 6b or 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 Fig. 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 provisions with the aid of which conventional reinforcing bars are fixed. As shown in FIG. 2, 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 Fig. 1 und 2, insbesondere aus Fig. 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 bis 3 mm breit und 2 mm tief.In an advantageous development, one feature is that the thicker plate 2 forming the outer jacket is preferably 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 to 3 mm wide and 2 mm deep.

Vorteilhaft wird das beschriebene Schalungselement in der Länge im Rastermass gefertigt, z. B. in den Massen 12,5,25,50 und 100 cm. Die Höhe kann z. B. 33,3 cm und die Breite z. B. 36 cm betragen.The formwork element described is advantageously made in length in pitch, z. B. in the masses 12.5, 25.50 and 100 cm. The height can e.g. B. 33.3 cm and the width z. B. 36 cm.
