Description
Holzbetonverbundkörper Die Erfindung betrifft einen Holzbetonverbundkörper mit in Nuten des Holzes eingreifenden eisenbewehrten Betonzähnen.Wood-concrete composite body The invention relates to a wood-concrete composite body with iron-reinforced concrete teeth engaging in grooves in the wood.
Die Festigkeit eines solchen Verbandes, insbesondere die Widerstandsfähigkeit der Betonzähne gegen Abscherung, wird nun gemäß der Erfindung in einfachster Weise dadurch erzielt, daß die Bewehrung der Betonzähne aus einer schraubenlinienförmig gewundenen Spirale mit zu den Holznuten gleichlaufender Längsachse besteht.The strength of such a bandage, especially its resilience the concrete teeth against shearing, is now according to the invention in the simplest way achieved in that the reinforcement of the concrete teeth from a helical there is a winding spiral with the longitudinal axis running at the same time as the wooden grooves.
Im Gegensatz zu einem früheren Vorschlag, Betonzähne in derartigen Verbundkörpern lediglich- mit einer Bewehrung aus eingelegten geraden Rund- oder Flacheisen zu versehen, wird hierbei eine vollkommene Sicherheit gegen Abscherung der Zähne mit besonders einfachen und einfach anzubringenden Mitteln erzielt, und zugleich ergibt sich hierbei der Vorteil, daß diese Bewehrung sowohl in Längs- und Querrichtung des Zahnes sowie auch nach beiden Seiten in Längsrichtung des Trägers gleich wirksam ist,.was bei wechselnder Richtung der Schubbeanspruchung (z. B. bei Zähnen in der Nähe der Balkenmitte) bei Veränderung der Laststellung sehr wichtig ist und z. B. mittels schief ins Holz eingetriebener Schrauben oder Stifte nicht in so einfacher Weise erzielt. werden könnte.In contrast to an earlier proposal, concrete teeth in such Composite bodies only with a reinforcement made of inserted straight round or Providing flat iron is a complete security against shearing the teeth achieved with particularly simple and easy to apply means, and at the same time there is the advantage that this reinforcement in both longitudinal and Transverse direction of the tooth as well as to both sides in the longitudinal direction of the carrier is equally effective, what if the direction of the shear load changes (e.g. with Teeth near the center of the beam) is very important when changing the load position is and z. B. by means of screws or pins driven into the wood at an angle achieved in such a simple way. could be.
Ausführungsbeispiele des Erfindungsgegenstandes sind in der Zeichnung dargestellt, und. zwar zeigt Fig. i einen Querschnitt durch eine Holzbetonplatte und Fig. 2 einen Schnitt nach Linie II-II in Fig. i.Embodiments of the subject matter of the invention are shown in the drawing illustrated, and. although Fig. i shows a cross section through a wood-concrete slab and FIG. 2 shows a section along line II-II in FIG.
Fig. 3 zeigt eine holzbewehrte Rippenplatte im Querschnitt und Fig. 4 einen Längsschnitt derselben, In Fig. i und 2 ist i eine Betonplatte und 2 eine Holztafel, welche zusammen den Verbundkörper bilden. Die Holztafel hat in bestimmten Abständen schief zur Faserrichtung verlaufende Nuten, welche entweder rechteckigen (2a) oder sches albenschwanzförmigen (2b) Querschnitt haben. In die Nuten sind als Bewehrung schraubenlinienförmig gewundene Eisenspiralen 3 mit zu den Holznuten gleichlaufender Längsachse eingelegt, welche vom Beton völlig umfaßt sind.Fig. 3 shows a wood-reinforced rib plate in cross section and Fig. 4 shows a longitudinal section of the same. In FIGS. I and 2, i is a concrete slab and 2 is one Wooden panels, which together form the composite body. The wooden panel has in certain Grooves running obliquely to the grain direction, which are either rectangular (2a) or sches alb tail-shaped (2b) have cross-section. The grooves are as Reinforcement helically wound iron spirals 3 with parallel to the wooden grooves Longitudinal axis inserted, which are completely encompassed by the concrete.
Bei der Rippenplatte nach Fig.3 und 4 greifen die Zähne der Betonplatte 5 in den Holzbalken 6 ein, und auf die Breite des Holzbalkens sind in die Nuten als Bewehrung schraubenlinienförmige Eisenspiralen 4 mit zu den Holznuten gleichlaufender Längsachse eingelegt.In the ribbed slab according to FIGS. 3 and 4, the teeth of the concrete slab grip 5 in the wooden beam 6, and on the width of the wooden beam are in the grooves as reinforcement, helical iron spirals 4 with parallel to the wooden grooves Longitudinal axis inserted.
Bei dem dargestellten Ausführungsbeispiel sind die Betonzähne schief zur Faserrichtung des Holzes angeordnet. In Fällen, wo kein Feuchtigkeitszutritt und somit kein Arbeiten des Holzes zu befürchten ist, können natürlich die Betonzähne auch weniger schief oder sogar senkrecht zur Faserrichtung des Holzes liegen, wobei die Wirkung der schraubenlinienförmigen Eisenspiralen in bezug auf die Aufnahme der Schubkräfte im Verbundkörper die gleiche bleibt.In the illustrated embodiment, the concrete teeth are crooked arranged to the grain of the wood. In cases where there is no access to moisture and therefore no working of the wood is to be feared, the concrete teeth can of course are also less crooked or even perpendicular to the grain of the wood, whereby the effect of the helical iron spirals in relation to the intake the shear forces in the composite body remains the same.
