Abstract

System and structural elements for storing the roof water either in a shell-type roof gutter, forming a storage area, for the purpose of domestic use or in concave tile pockets or in gutter spaces, running in the ridge direction, for the purpose of microclimatic, ecological use, as a whole in order to reduce outflow into the rainwater-discharge devices. <IMAGE>

Description

Der Erfindungsgegenstand ist eine aus einzelnen Bauelementen gefügte Anlage zur Speicherung von Dachregenwasser. Eine derartige Anlage ist nach Form und Funktion bis jetzt nicht bekannt. Man vermeidet es, das Regenwasser im Dach zu speichern, sondern alle bekannte Dachtechniken haben zum Ziel, das Regenwasser möglichst schnell zur Kanalisation usw. zu leiten. Die Idee der Speicherung im Dach erhält deswegen eine besondere Erfindungshöhe. Es wird in der Weise ein technischer Fortschritt besonders erzielt, daß die Regenwassermengen reduziert werden, die Kanalisationen weniger belastet werden, das Element Wasser gespart wird bzw. das in der Dachhaut gepeicherte Wasser kleinklimatisch verwertet wird, in dem die Verdunstungskälte zur Kühlung, die Frosterstarrungswärme für den Hauskörper verwertet wird. Gleichzeitig kann die in letzter Zeit immer häufiger ange strebte Dachbegrünung auch in geneigten Dächern erfolgen.The subject of the invention is one of individual components joined system for storing roof rainwater. Such a system is so far in terms of form and function not known. You avoid the rainwater in the roof store, but all known roofing techniques have to Aim to get the rainwater to the sewers as quickly as possible etc. to lead. Receives the idea of storing in the roof therefore a special level of invention. It will be in the Way a technical advance particularly achieved that the amounts of rainwater are reduced, the sewers be less burdened, the element water is saved or the water stored in the roof cladding is small climatic is used in which the evaporative cooling for cooling, the freezing heat is used for the house body. At the same time, it has become increasingly common lately aspired green roofs also take place in sloping roofs.

Die Erfindungsaufgabe ist wie folgt gelöst:
Das Regenwasser wird in einer Dachrinne in der Weise ge speichert, daß sie in einer Schale (1), die unter dem Dachvorsprung hängend (8, 9) angebracht ist, mit ent sprechenden Speicherraum aufgefangen wird und über ein Rohrsystem (2) der häuslichen Verwertung zugeführt wird. In einem Speicherrohr (3) kann die Schale (1) in ihrer Wirkung erhöht werden. Die Schale (1) kann auf verschiedene Weise am Sparren (21) bzw. an der Hausaußenwand last tragend befestigt werden, mit Bügeln (9, 10, 11), mit Halteböcken (8), auch zusätzlich durch eine Einschlitzung im Sparren (1 b), oder auch über einen Haltewulst (14), der von einem Haltebock gefaßt ist und dadurch die Lasten über die Mauer ableitet.The task of the invention is solved as follows:
The rainwater is stored in a gutter in such a way that it is collected in a bowl ( 1 ), which is attached under the eaves ( 8, 9 ), with appropriate storage space and via a pipe system ( 2 ) for domestic recycling is fed. The effect of the shell ( 1 ) can be increased in a storage tube ( 3 ). The shell ( 1 ) can be fastened in a load-bearing manner to the rafters ( 21 ) or to the outside wall of the house, with brackets ( 9, 10, 11 ), with support brackets ( 8 ), also additionally by a slit in the rafters ( 1 b ) , or also via a retaining bead ( 14 ), which is gripped by a bracket and thereby derives the loads over the wall.

Die Speicherung zum Zwecke der kleinklimatischen Verwertung des Regenwassers kann in der Weise erfolgen, daß die Ziegel taschen (20) mit ihrer konkaven Form bis zum Überlaufen (7) in einem Speicherraum (23) den größten Teil des Regens auffangen und verdunsten und gefrieren lassen. Die Ziegel taschen können die Größe der Dachziegel erhalten, sie können aber auch so lang sein, wie der Sparrenabstand.The storage for the purpose of small-scale recycling of rainwater can be done in such a way that the brick pockets ( 20 ) with their concave shape until they overflow ( 7 ) in a storage space ( 23 ) collect and evaporate and freeze most of the rain. The tile pockets can be as large as the roof tiles, but they can also be as long as the rafter spacing.

Die Dachhaut kann auch aus Wellplatten mit runden und trapez artigem Querschnitt (20 b, 20 c) oder auch aus einzelnen Dach rinnen (20 d) gebildet werden. Die Wellen verlaufen in neu heitlicher Weise jedoch in Traufen- bzw. Firstrichtung. Die Querschnittsform wird dabei optimiert in der Weise, daß der traufenseitige Steg steiler verläuft als der firstseitige.The roof skin can also be formed from corrugated sheets with a round and trapezoidal cross-section ( 20 b , 20 c) or from individual gutters ( 20 d) . The waves run in a new way but in eaves or ridge direction. The cross-sectional shape is optimized in such a way that the eaves-side web is steeper than the ridge-side.
