Description
Die Erfindung betrifft ein vorgefertigtes Wandelement aus Holzspanbeton. Holzspanbeton ist eine Mischung aus Holzspänen und Zement als Bindemittel. Die Holzspäne sind dabei durch das Eindringen von mineralischen Feinstoffen in die Holzporen vormineralisiert. Im Stand der Technik sind Mantelbetonwände bekannt, welche aus Holzspanbetonplatten bestehen, die als verlorene Schalung in senkrechter Richtung in Abstand voneinander aufgestellt werden und mit Beton ausgefüllt werden. Außerdem sind Schalungssteine aus Holzspanbeton bekannt, welche mit einer Innen- oder Außendämmung versehen sind, siehe Lohmeyer-Bauphysik, Ausg. 1995, Seite 135, Verlag B. G. Teubner, Stuttgart. Die bekannten Wandsysteme sind noch verbesserungsbedürftig betreffend den Wärmedämmwert und die Dampfdiffusion. Desweiteren sind die bekannten Systeme nicht ökologisch in der Herstellung. Sie sind zu aufwendig und daher unwirtschaftlich und haben ein hohes Volumengewicht.The invention relates to a prefabricated Wall element made of chipboard. Wood chip concrete is one Mixture of wood chips and cement as a binder. The Wood chips are due to the penetration of mineral Fine materials pre-mineralized in the wood pores. In the state of the Technique are known concrete wall, which from Chipboard panels exist as lost formwork set up at a distance from each other in the vertical direction and be filled with concrete. Also are Formwork blocks made of chipboard known, which with a Internal or external insulation is provided, see Lohmeyer building physics, Edition 1995, page 135, publisher B.G. Teubner, Stuttgart. The known wall systems are still in need of improvement regarding the thermal insulation value and Vapor diffusion. Furthermore, the known systems not ecological in production. They are too expensive and therefore uneconomical and have a high Volume weight.

Es können Wandelemente mit Türausschnitten und Fensterausschnitte mit Rolladenkasten hergestellt werden. Die oberen, unteren und seitlichen Schalungen für den Rolladenkasten sind vorzugsweise zweiteilig ausgeführt und an ihren aneinanderstoßenden Enden um 45° abgeschrägt, damit die Schalung einfach entfernt werden kann. Vorzugsweise bleibt diese Schalung als Transportsicherung in dem Fertigteil zurück und wird erst nach der Montage auf der Baustelle entfernt.Preferably has at least one plate of the Formwork frame one inside, on both sides beveled groove in the vertical post of the Wall element is to be attached and another plate of the Formwork frame has an inner, side bevelled projection on which a post of the Truss frame is to be attached. In addition, a Formwork piece bevelled on both sides on the side facing surface of a post of the truss frame be attached to form a laterally opening, bevelled on both sides in one Side surface of the wall element for producing a Corner connection between two adjacent wall elements. It can wall elements with door cutouts and Window cutouts can be made with roller shutter boxes. The top, bottom and side formwork for the Roller shutter box are preferably made in two parts bevelled by 45 ° at their abutting ends, so that the formwork can be easily removed. This formwork preferably remains as a transport lock in the finished part and is only opened after assembly the construction site away.
Gleiches gilt ebenfalls für die Fenster- und Türschalungen, welche beidseitig offen sind und nach der Montage schnell und leicht ausschalbar sind.The same applies to the window and Door formwork, which is open on both sides and after the Assembly can be quickly and easily removed.
