Description

Beschreibung des "Sparrenhaken" Bisher wurden die einzelnen Sparren bei freitragenden Dächern und auskragender Traufe in Verbindung mit einer Holzknagge und 2 Bolzen auf eine Holzscnwelle gesetzt. Ausserdem wurde die Relzschwelle gegen abheben durch An- kerbolzen gesichert. Der f Sparrenhakentt Form A besteht lediglich aus einem Flachstahl ca. e==. 6o. lo. 2oo und ist versehen mit 2 Bohrlöchern für schwache Bolzen, die in den Beton geschos- sen werden. Wenn ein Anschießen des Hakens nicht gewünscht wird, kann man einen Längsdübel in den Beton einlegen und den Haken mit 2 Holzschrauben befestigen. Bei genauerer Einschalung des Sparrenwiderl@gers ist es möglich, in diesem Falle den Sparrenhaken D zu verwenden. Dazu ist es notwendig, in Höhe der Decke eine Dreikantleiste einzulegen. description of "Rafter hook" So far, the individual rafters have been cantilevered Roofs and cantilevered eaves in connection with one Wooden catch and 2 bolts placed on a wooden screw shaft. In addition, the threshold against lifting by raising bolt secured. The r rafter hook type A only consists of a flat steel approx. e ==. 6o. lo. 2oo and is marked with 2 Drill holes for weak bolts that are shot into the concrete be sen. If you do not want to shoot the hook, you can insert a lengthwise dowel in the concrete and fix the hook with 2 wood screws. If the rafter bar is encased more precisely, it is possible to use the rafter hook D in this case. To do this, it is necessary to insert a triangular strip at the level of the ceiling.

Der Haken D wird dann nur in die Dreikantleiste eingeschlagen.The hook D is then only hammered into the triangular strip.

Ist man in der Lage einen Falz zu betonieren, besonders bei Betondrempeln, so verwendet man die Form B. Diese Form ist sehr günstig, weil in diesem Falle nur der Haken in den Falz zu legen ist und dadurch keine weitere Befestigung erforderlich ist. Nird beim Betonieren des Falzes mit einer Maßdifferenz gerechnet, kann man den C-Haken verwenden.Is it possible to concret a rebate, especially with concrete jambs, so one uses the form B. This form is very favorable, because in this case only the hook is to be placed in the fold and therefore no further fastening is required is. If a dimension difference is not expected when concreting the rebate, one can use the C-hook.

Dieser besteht aus 2 Teilen die ineinander mittels eines Langloches verschieblich sind.This consists of 2 parts that fit into each other by means of an elongated hole are movable.

Allgemein schneidet der Zimmermann mit einer breitgeschränkten Säge den Sparren kurz an und schlägt mit einem Stemmeisen mittels 2-3 Schlägen das Langholz für den Haken heraus.In general, the carpenter cuts with a wide-set saw Briefly on the rafter and hit the long wood with a chisel with 2-3 blows for the hook out.

Bei größerem betrieb kann diese Arbeit mittels eines Fräsers getan werden. An der Baustelle selbst hat der Zimmermann nur die Aufgabe, die Sparren einzuhaken. Die Sparrenhaken werden im allgemeinen für eine Dachneigung von 45 geformt.For larger operations, this work can be done using a milling cutter will. At the construction site, the carpenter's job is only to do the rafters to hook. The rafter hooks are generally shaped for a 45 roof pitch.

Wenn es bei stark abweichenden Dachneigungen notwendig wird, kann man den Haken mit 1-2 Schlägen kalt kröpfen.If it becomes necessary with strongly deviating roof pitches, can you crop the hook with 1-2 cold strokes.

Man kann allerdings auch die Schalmaße am Betondrempel ändern lassen, wenn man die Hakenform beibehalten will.However, you can also change the dimensions of the formwork on the concrete jamb, if you want to keep the hook shape.
