Description

Die Erfindung betrifft eine mit Beton verfüllbare Streifenfundamentschalung und ein unter Verwendung dieser Streifenfundamentschalung hergestelltes Streifenfundament.The invention relates to a strip foundation formwork that can be filled with concrete and one using this strip foundation formwork manufactured strip foundation.

In der Bautechnik ist allgemein bekannt, Streifenfundamente unter Verwendung einer aus Holzbrettern und dergleichen bestehenden Streifenfundamentschalung herzustellen, die nach Erhärten des Betons entfernt und erneut wiederverwendet wird.In building technology, strip foundations are generally known using one of wooden boards and the like existing strip foundation formwork that removed after hardening of the concrete and reused becomes.

Der Erfindung liegt die Aufgabe zugrunde, eine Streifenfundamentschalung so auszubilden, daß die bei deren Verwendung zur Herstellung eines Streifenfundamentes erforderlichen Manipulationen erheblich reduziert sind.The invention has for its object a strip foundation formwork train so that when using them required to create a strip foundation Manipulations are significantly reduced.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Streifenfundamentschalung gekennzeichnet durch eine Ausbildung als verlorene Schalung in Form von bodenlosen Hohlbausteinen, die mit offenen Anschlußstirnflächen flächig stoßend aneinandersetzbar sind und in ihren Decken Betoneinfüllöffnungen aufweisen.The strip foundation formwork according to the invention is used to achieve this object characterized by training as lost formwork in the form of bottomless hollow bricks, those with open connection faces are juxtaposed and in their blankets Have concrete filling openings.

Nach bevorzugter Ausführungsform weisen die Hohlbausteine einen umgekehrt U-förmigen Querschnitt mit zur Decke hin aufeinander zulaufenden Seitenwänden auf. Weiterhin empfiehlt es sich, die Anordnung so zu treffen, daß die Hohlbausteine an der Außenseite ihrer Seitenwände Verstärkungsrippen bildende Aussparungen aufweisen. Darüber hinaus ist es zweckmäßig, wenn die Decken auf ihrer Oberseite längslaufende Rinnen aufweisen, von denen die Betoneinfüllöffnungen ausgehen. Diese Rinnen können beim Einfüllen des Betons als Betonaufnahmepuffer dienen; es besteht aber auch die Möglichkeit, in diese Rinnen nach dem Einfüllen des Betons Isoliermaterialstreifen einzulegen. Günstig ist jedenfalls, wenn sich die Betoneinfüllöffnungen zum Inneren des Hohlraumes hin allmählich erweitern, weil so ein vollständiges Ausfüllen des Hohlbausteins mit dem Beton ohne Bildung von Luftblasen ermöglicht werden kann. Besonders einfache Transportmöglichkeiten ergeben sich, wenn die Hohlbausteine reiterartig stapelbar sind. Zur Vermeidung von Kältebrücken zum später aufgesetzten Bauwerk hin, sind die Hohlbausteine nach einer bevorzugten Ausführungsform aus einem Isoliermaterial, vorzugsweise Polystyrol hergestellt. Darüber hinaus wird das Erstellen einer vollständigen Streifenfundamentschalung erleichtert, wenn einzelne Hohlbausteine als Sonderbausteine, z.B. in einer Ausführung als Eckbaustein oder in einer Ausführung mit zumindest einer weiteren Anschlußstirnfläche im Bereich der Seitenwände zur Verfügung stehen.According to a preferred embodiment, the hollow building blocks have an inverted U-shaped cross section with the ceiling side walls converging. Farther it is advisable to make the arrangement so that the Hollow blocks on the outside of their side walls reinforcing ribs have forming recesses. Furthermore it is useful if the blankets are on their top have longitudinal channels, of which the concrete filling openings going out. These channels can be used when filling the Concrete serve as a concrete absorption buffer; but it also exists the possibility to fill these channels after filling the Insert concrete strips of insulating material. Is cheap at least if the concrete filling openings face the inside of the cavity gradually expand, because such a complete Filling the hollow block with the concrete without Formation of air bubbles can be made possible. Especially easy transport options arise when the Hollow blocks can be stacked like a rider. To avoid from cold bridges to the structure that will be added later the hollow building blocks according to a preferred embodiment made of an insulating material, preferably polystyrene. It also creates a complete Strip foundation formwork relieved when single Hollow blocks as special blocks, e.g. in one version as a corner block or in a version with at least a further connection end face in the area of the side walls be available.

Gegenstand der Erfindung ist auch ein Streifenfundament, das unter Verwendung der erfindungsgemäßen Streifenfundamentschalung hergestellt ist.The invention also relates to a strip foundation, that using the strip foundation formwork according to the invention is made.

In Fig. 7 erkennt man eine mit Beton verfüllbare Streifenfundamentschalung, die als verlorene Schalung in Form von bodenlosen Hohlbausteinen 1 ausgebildet ist, die mit offenen Anschlußstirnflächen 2 flächig stoßend aneinander gesetzt sind und an ihren Decken 3 Betoneinfüllöffnungen 4 aufweisen. Aus den Fig. 1 bis 6 entnimmt man, daß die Hohlbausteine 1 einen umgekehrt U-förmigen Querschnitt mit zur Decke 3 hin aufeinander zulaufenden Seitenwänden 5 aufweisen. An der Außenseite weisen die Seitenwände 5 Verstärkungsrippen 6 auf, die gleichsam Aussparungen 7 bilden. Die Decken 3 sind auf ihrer Oberseite mit längslaufenden Rinnen 8 versehen, von denen die Betoneinfüllöffnungen 4 ausgehen. Bei der Ausführungsform nach den Fig. 1, 4 und 5 sind jeweils zwei solcher Rinnen 8 mit einem dazwischenliegenden Steg 9 vorgesehen. Bei der Ausführungsform nach Fig. 6 ist dagegen nur eine einzige Rinne 8 vorgesehen. Aus der Fig. 2 ist jedenfalls erkennbar, daß die Betoneinfüllöffnungen 4 sich zum Inneren 10 des Hohlbausteines hin allmählich erweitern. Dasselbe gilt natürlich für das Innere 10 des Hohlbausteines 1 aufgrund der schräg verlaufenden Seitenwände 5.7 shows a strip foundation formwork that can be filled with concrete, which as lost formwork in the form of bottomless hollow building blocks 1 is formed with open connection faces 2 abutting against each other are set and 3 concrete filling openings 4 on their ceilings exhibit. From Figs. 1 to 6 it can be seen that the hollow blocks 1 an inverted U-shaped cross-section with Ceiling 3 have side walls 5 converging towards each other. The side walls have 5 reinforcing ribs on the outside 6, which form recesses 7 as it were. The Blankets 3 are on their top with longitudinal channels 8 provided, from which the concrete filling openings 4 extend. In the embodiment according to FIGS. 1, 4 and 5 two such channels 8 with one in between Web 9 provided. 6 in the embodiment however, only a single channel 8 is provided. From FIG. 2 is in any case recognizable that the concrete filling openings 4th gradually towards the interior 10 of the hollow block expand. The same naturally applies to the interior 10 of the Hollow building block 1 due to the sloping side walls 5.

Fig. 3 zeigt, daß die Hohlbausteine 1 reiterartig stapelbar sind, so daß sich keinerlei Transportprobleme ergeben. Die beschriebenen Hohlbausteine 1 sind aus einem Isoliermaterial, vorzugsweise Polystyrol hergestellt. Dadurch können Kältebrücken zwischen dem Boden und dem auf dem Streifenfundament aufgesetzten Bauwerk weitgehend unterbunden werden.Fig. 3 shows that the hollow blocks 1 stackable like a rider are, so that there are no transport problems. The described hollow blocks 1 are made of an insulating material, preferably made of polystyrene. Thereby can cold bridges between the floor and that on the The stripe foundation of the structure is largely prevented become.
