Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Decke, z.B. eine Zwischendecke in einem Gebäude gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a blanket, e.g. an intermediate ceiling in a building according to the preamble of claim 1.

Stand der TechnikState of the art

Aus einer gegossenen Betonschicht bestehende Decken anzulegen und fest mit tragendem Mauerwerk oder Betonmauern zu verbinden, ist gewöhnlich unproblematisch, da die Decke bis zur Aussenseite durchgezogen werden kann und somit ihr Randbereich direkt auf den sie tragenden Mauern aufliegt. Dagegen hat es sich als schwierig erwiesen, eine Betonschicht in einen sie tragenden Holzrahmen einzugiessen und mit demselben hinreichend zuverlässig zu verbinden. Dies ist jedoch erforderlich, wenn etwa die Aussenwand eines Gebäudes aus Holz besteht und ein Durchziehen der Betonschicht bis zur Aussenseite vermieden werden soll, z.B. zur Vermeidung von Kältebrücken.Laying existing ceilings from a poured concrete layer and connecting them firmly with load-bearing masonry or concrete walls is usually unproblematic, as the ceiling can be pulled through to the outside and thus its edge area rests directly on the walls supporting it. By contrast, it has proved difficult to pour a concrete layer into a wooden frame carrying it and to connect it with sufficient reliability. However, this is necessary if, for example, the outer wall of a building is made of wood and pulling through the concrete layer to the outside is to be avoided, e.g. to avoid cold spots.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zu Grunde, eine Decke anzugeben, bei der die Betonschicht von einem Holzrahmen umgeben ist und die Betonschicht zuverlässig mit demselben verbunden ist und überwiegend von ihm getragen wird. Diese Aufgabe wird durch die Merkmale im Kennzeichen des Anspruchs 1 gelöst.The invention is based on the object to provide a ceiling in which the concrete layer is surrounded by a wooden frame and the concrete layer is reliably connected to the same and is mainly supported by him. This object is solved by the features in the characterizing part of claim 1.

Die Verbindung der Betonschicht mit dem Rahmen bei der erfindungsgemässen Decke hat sich als äusserst tragfähig erwiesen. In vielen Fällen treten sogar eher in der Betonschicht selbst Brüche auf als an der Grenzfläche zwischen Holzrahmen und Betonschicht. Die Verbindung kann ausserdem aus leicht beschaffbaren, verhältnismässig billigen Standardteilen sehr einfach hergestellt werden.The connection of the concrete layer to the frame in the inventive cover has proved to be extremely sustainable. In many cases, fractures occur even in the concrete layer itself rather than at the interface between the wooden frame and the concrete layer. The compound can also be easily made from easily procurable, relatively cheap standard parts.

Wege zur Ausführung der ErfindungWays to carry out the invention

Die Decke umfasst (Fig. 1) eine waagrechte Betonschicht 1 und einen dieselbe vorzugsweise lückenlos umgebenden Holzrahmen 2. Letzterer besteht z.B. wie dargestellt aus geraden Balken 3 und Eckstücken 4, welche jeweils mit zwei Balken 3 so verbunden sind, dass diese einen rechten Winkel einschliessen. Die Verbindung zwischen einem Balken 3 und einem an denselben anschliessenden Eckstück 4 wird jeweils durch eine innere Verbindungsplatte 5 und eine äussere Verbindungsplatte 6 hergestellt, welche jeweils in aneinander anschliessenden Ausnehmungen am Balken 3 und am Eckstück 4 liegen. Die innere Verbindungsplatte 5 und die äussere Verbindungsplatte 6 wiederum sind durch Rundstäbe 7, die jeweils deckungsgleich aneinander anschliessende Querbohrungen im Balken 3 oder dem Eckstück 4 und der inneren Verbindungsplatte 5 und der äusseren Verbindungsplatte 6 ausfüllen, mit dem Balken 3 und dem Eckstück 4 verbunden. Der Holzrahmen kann bei grundsätzlich gleichem Aufbau auch komplexere Form haben als dargestellt, mit Vorsprüngen und Einsprüngen, spitzen und stumpfen Winkeln und gebogenen Abschnitten. Die Betonschicht 1 kann armiert sein. Sie kann auch an vom Holzrahmen 2 entfernten Stellen zusätzlich gestützt sein.The blanket includes ( Fig. 1 The latter consists for example of straight beams 3 and corner pieces 4, which are each connected to two beams 3 in such a way that they enclose a right angle. The connection between a beam 3 and a corner piece 4 adjoining the same is produced in each case by an inner connecting plate 5 and an outer connecting plate 6, which are respectively in adjoining recesses on the beam 3 and the corner piece 4 are. The inner connecting plate 5 and the outer connecting plate 6 in turn are connected by round rods 7, each congruent adjoining transverse bores in the beam 3 or the corner piece 4 and the inner connecting plate 5 and the outer connecting plate 6, with the beam 3 and the corner piece 4. The wood frame can also have a more complex shape than shown, with projections and projections, acute and obtuse angles and curved sections. The concrete layer 1 can be reinforced. It can also be supported on the remote from the wooden frame 2 places.

Der Balken 3 besteht (Fig. 2) jeweils aus einem Verbundmaterial mit dünnen Holzplatten und ist z.B. wie dargestellt als Mehrschichtplatte 8 ausgebildet oder auch als Furnierschichtplatte oder Sperrholzplatte. Die Eckstücke 4 sind ähnlich aufgebaut.The bar 3 consists ( Fig. 2 ) Each of a composite material with thin wood panels and is, for example, as shown formed as a multi-layer plate 8 or as a veneer layer board or plywood. The corner pieces 4 are constructed similarly.

An der Innenseite bilden die Balken 3 und die Eckstücke 4 eine umlaufende Grenzfläche 9, die im Beispiel stückweise eben und senkrecht ist und zu der die Holzplatten des Balkens 3 parallel sind. Eine Randfläche der Betonschicht 1 schliesst unmittelbar an die Grenzfläche 9 an. Mit Abständen, die je nach der lokalen Belastung unterschiedlich sein können, aber in der Regel zwischen 10cm und 30cm liegen und vorzugsweise ca. 25cm betragen, sind am Holzrahmen 2, in Umlaufrichtung aufeinanderfolgend, Gruppen 10 von Verbindungsteilen angebracht, welche jeweils als gerade Bolzen 11a-d (s. Fig. 2, 3, die Betonschicht ist in Fig. 2 nur angedeutet und in Fig. 3 weggelassen) ausgebildet sind.On the inside, the beams 3 and the corner pieces 4 form a peripheral boundary surface 9, which in the example is piecewise flat and perpendicular and to which the wood panels of the beam 3 are parallel. An edge surface of the concrete layer 1 immediately adjoins the interface 9. With distances that may vary depending on the local load, but are usually between 10cm and 30cm and preferably be about 25cm, the wooden frame 2, successively in the circumferential direction, groups 10 of connecting parts attached, each as a straight pin 11a -d (s. Fig. 2, 3rd , the concrete layer is in Fig. 2 only hinted at and in Fig. 3 omitted) are formed.

Die Bolzen 11a-d sind jeweils als einstückige Schraubenbolzen ausgebildet, z.B. SFS WT-T 8.2x245. Jeder der Bolzen 11a-d weist ein von einer Spitze ausgehendes vorderes Gewinde 12 auf, das als Schneidgewinde ausgebildet ist. Mit Abstand folgt ein hinteres Gewinde 13, das bis zu einem Kopf 14 durchgezogen ist und dessen Gänge eine Folge von leicht schrägen Querrillen bilden. Der Kopf 14 ist so ausgebildet, dass der Eingriff eines Drehwerkzeugs möglich ist, z.B. ist er mit einem Schlitz oder einer anderen Vertiefung versehen. Jeder der Bolzen 11a-d ist mit einem Verankerungsabschnitt, der von der Spitze bis etwa zur Mitte, d.h. etwas über das Ende des vorderen Gewindes 12 hinaus reicht, in einem Balken 3 des Holzrahmens 2 versenkt und durch das vordere Gewinde 12 an demselben zuverlässig festgehalten. Das hintere Ende ragt an der Grenzfläche 9 aus dem Holzbalken 3 und bildet einen Halteabschnitt, der vollständig in der Betonschicht 1 eingebettet ist. Die vom hinteren Gewinde 13 gebildeten Querrillen stellen dabei eine feste, insbesondere auch zugfeste Verbindung mit derselben sicher.The bolts 11a-d are each formed as one-piece bolts, e.g. SFS WT-T 8.2x245. Each of the bolts 11a-d has a tip thread 12 formed as a cutting thread. By far, a rear thread follows 13, which is pulled through to a head 14 and whose courses form a series of slightly oblique transverse grooves. The head 14 is designed so that the engagement of a turning tool is possible, e.g. he is provided with a slot or other depression. Each of the bolts 11a-d is provided with an anchoring portion extending from the tip to about the middle, i. extends slightly beyond the end of the front thread 12 out, sunk in a bar 3 of the timber frame 2 and reliably held by the front thread 12 at the same. The rear end protrudes from the wooden beam 3 at the interface 9 and forms a holding portion that is completely embedded in the concrete layer 1. The transverse grooves formed by the rear thread 13 thereby make a firm, in particular also tensile connection with the same safe.

Eine Gruppe 10 besteht jeweils aus vier Bolzen 11a-d, von denen zwei Bolzen 11a,b senkrecht zur Grenzfläche 9, d.h. im Beispiel waagrecht ausgerichtet und mit einem Abstand von zwischen 10cm und 15cm, im Beispiel von ca. 14cm, übereinander angeordnet sind. Auf der einen Seite der Bolzen 11a,b ist, vorzugsweise um zwischen 0,5cm und 2,5cm, im Beispiel um ca. 1cm seitlich versetzt, ein schräg nach oben weisender, in einer zur Grenzfläche 9 senkrechten Ebene liegender Bolzen 11c angeordnet. Er durchstösst die Grenzfläche 9 auf einer in der Mitte zwischen der Höhe der Bolzen 11a und 11b liegenden Höhe und schliesst mit ihr einen Winkel von ca. 45° ein. Auf der anderen Seite der Bolzen 11a,b ist, in gleicher Weise seitlich versetzt wie der Bolzen 11c, ein schräg nach unten weisender, ebenfalls in einer zur Grenzfläche 9 senkrechten Ebene liegender Bolzen 11d angebracht. Er durchstösst die Grenzfläche 9 etwa auf der gleichen Höhe wie der schräg nach oben gerichtete Bolzen 11c und schliesst mit ihr ebenfalls einen Winkel von ca. 45° ein. Die Winkel zwischen der Grenzfläche 9 und den Bolzen 11c, 11d können von 45° abweichen, vorzugsweise liegen sie zwischen 30° und 60°.A group 10 consists in each case of four bolts 11a-d, of which two bolts 11a, b are arranged perpendicular to the interface 9, ie horizontally aligned in the example and at a distance of between 10cm and 15cm, in the example of about 14cm, one above the other. On the one side of the bolt 11a, b, preferably by between 0.5 cm and 2.5 cm, in the example offset by about 1cm laterally, an obliquely upwardly facing, in a plane perpendicular to the boundary surface 9 bolt 11c arranged. He pierces the interface 9 on a lying in the middle between the height of the bolt 11 a and 11 b height and closes with it an angle of about 45 °. On the other side of the bolt 11a, b is, in the same way laterally offset as the bolt 11c, an obliquely downward pointing, also in a plane perpendicular to the boundary surface 9 bolt 11d attached. He pierces the interface 9 at about the same height as the obliquely upwardly directed bolt 11c and also encloses with it an angle of about 45 °. The angles between the interface 9 and the pins 11c, 11d may deviate from 45 °, preferably between 30 ° and 60 °.

Bei der Herstellung der Decke wird zuerst der Holzrahmen 2 aufgebaut. Er kann ganz oder teilweise auf einer Aussenwand abgestützt sein, welche vorzugsweise ebenfalls aus Holz besteht, z.B. aus nebeneinander angeordneten senkrechten Vierkantpfosten. Anschliessend oder auch schon vor dem Zusammenbau werden die Verbindungsteile am Holzrahmen 2 befestigt, also im Beispiel die Bolzen 11a-d der Gruppen 10 mittels eines geeigneten Werkzeugs in die Balken 3 eingeschraubt und eine Schalung angelegt, welche aus in üblicher Weise mittels Stützen auf einem Boden oder einer bereits fertigen unteren Decke abgestützten Brettern bestehen kann, die auf der Höhe der die Grenzfläche 9 an der Unterseite berandenden Unterkante des Holzrahmens 2 angeordnet sind. Anschliessend wird, gegebenenfalls nach Einbringen der Armierung, Betonmasse auf die Schalung gegossen, die den Holzrahmen 2 ausfüllt und die Verbindungsteile vollständig umgibt. Nach Aushärtung des Betons wird die Schalung entfernt. Die Betonschicht 1 ist nun durch die eingegossenen Verbindungsteile zuverlässig mit dem Holzrahmen 2, in dem dieselben verankert sind, verbunden.In the production of the ceiling, the wooden frame 2 is first constructed. It may be wholly or partially supported on an outer wall, which preferably also consists of wood, for example, arranged side by side vertical square posts. Subsequently, or even before assembly, the connecting parts are attached to the wooden frame 2, that is screwed in the example, the bolts 11a-d of the groups 10 by means of a suitable tool in the beam 3 and created a formwork, which in the usual way by means of supports on a floor or a already finished lower ceiling supported boards can be made, which are arranged at the height of the boundary surface 9 on the underside bordering the lower edge of the wooden frame 2. Subsequently, if necessary after introducing the reinforcement, poured concrete mass on the formwork, which fills the wooden frame 2 and completely surrounds the connecting parts. After hardening of the concrete, the formwork is removed. The concrete layer 1 is now reliably connected by the cast-in connection parts with the wooden frame 2, in which they are anchored.
