Description

mittels Kette einstellbare Schließvorrichtung für Betonstampfformen. Zum Schließen von Betonstampfformen werden Schließvorrichtungen benötigt, die im Gegensatz zu den Schließvorrichtungen, bei denen jedesmal zu erneuernde Spanndrähte zur Verwendung kommen, wiederholt benutzbar sind. Die in Vorschlag gebrachten Schließvorrichtungen, die aus einer Kette mit Spannschloß bestehen, sind unzweckmäßig, weil die Kette sich niemals so um die Stampfform legen läßt, daß die Form unter dem Stampfdruck nicht nachgeben kann, denn da die Gliederteilung der Kette nur in Ausnahmefällen mit der Breite der Stampfformflächen übereinstimmt, ist die ringsum führende Spannkette nur benutzbar, wenn es sich um nahezu kreisrunde Formen handelt.Locking device for concrete ramming molds adjustable by means of a chain. To close concrete ramming forms, locking devices are required that are in In contrast to the closing devices, where the tension wires have to be renewed every time come to use, can be used repeatedly. The proposed locking devices, which consist of a chain with a turnbuckle are unsuitable because the chain can never be placed around the ramming form in such a way that the form is under the ramming pressure cannot give in, because there is the division of limbs the chain only in exceptional cases coincides with the width of the rammed form surfaces, this is all around Leading tension chain can only be used if the shape is almost circular.

Andere Schließvorrichtungen aus winklig gebogenen Flacheisen, die mit ihren Enden übereinander zu legen und zu verbinden sind, lassen sich nur für Stampfformen von der gleichen Winkelform verwenden und verursachen hohe Anschaffungs- und Beförderungskosten, weil die Form auf dem ganzen Umfang von diesen Eisenwinkeln umschlossen werden muß.Other locking devices made of angled flat iron that with their ends to be placed on top of each other and connected, can only be used for Use stamped forms of the same angular shape and cause high purchase costs and transportation costs because the shape on the whole circumference of these iron angles must be enclosed.

Aus diesen Gründen sind Schließvorrichtungen vorzuziehen, bei denen die Eisenteile nur dazu dienen, ähnlich der früher in Vorschlag gebrachten Drahtschleifen die Druckhölzer gegen die Form zu pressen.For these reasons, locking devices are preferable in which the iron parts only serve, similar to the wire loops previously suggested to press the compression timbers against the mold.

Da aber Kanthölzer zu wertvoll sind und sich selten in genügender Menge auf der Baustelle befinden, wogegen es an Brettern und Brettstücken niemals mangelt-, ist nach der Erfindung die Schließvorrichtung so gestaltet, daß der Druck durch Brettstücke aufgenommen werden kann, die durch die Schließvorrichtung hochkantig zur Stampfformoberfläche gehalten werden und infolgedessen ohne Gefahr des Durchbiegens Drücke aufnehmen können, die nur Kanthölzer von erheblich großem Querschnitt auszuhalten vermögen.But since squared timbers are too valuable and rarely in sufficient Amount on the construction site, whereas boards and pieces of boards never do lacking, according to the invention, the locking device is designed so that the pressure can be accommodated by pieces of board, which are edged by the locking device be held to the rammed form surface and consequently without the risk of sagging Can absorb pressures that only squared timber with a considerably large cross-section can withstand capital.

Im wesentlichen besteht die Erfindung aus einer nachstellbaren Spannkette mit zwei langen, schleifenförmigen Endgliedern, in die sich die Druckbretter einschieben lassen, und die unter dem Spanndruck der Kette hochkantig zur Druckfläche gehalten werden.The invention essentially consists of an adjustable tension chain with two long, loop-shaped end links into which the pressure boards slide let, and held upright to the pressure surface under the tension of the chain will.

Auf der Zeichnung ist in der Abb. i die Schließvorrichtung von vorn gesehen dargestellt. Die Abb. a zeigt die mit Haken versehene öse im Längsschnitt und die Abb.3 und ¢ im Querschnitt und in der Außenansicht eine mit der Schließvorrichtung zusammengefügte Stampfform.In the drawing, Fig. I shows the locking device from the front seen shown. Fig. A shows the hooked eyelet in a longitudinal section and Fig.3 and ¢ in cross section and in the external view one with the locking device assembled stamped form.

Von den länglich gestalteten äsen a und b steht die Öse a mit der Kette d vorteilhaft in dauernd fester Verbindung. Die Öse b besitzt an dem einen Ende eine hakenartige Aufbiegung g mit Einschnitt!, wodurch Schultern gebildet werden, die dem jeweils hinter dem Haken g eingelegten Kettenglied als Gegenlage dienen.Of the elongated ears a and b , the eyelet a is advantageously permanently connected to the chain d. The eyelet b has at one end a hook-like bend g with an incision! Whereby shoulders are formed which serve as a counter-surface to the chain link inserted behind the hook g.

Mit Hilfe der Kette d und des Hakens g kann die Schließvorrichtung der jeweiligen Dicke der Stampfform einfach dadurch angepaßt werden, daß das entsprechende Kettenglied in den Einschnitt! der öse b gelegt wird.With the help of the chain d and the hook g, the locking device the respective thickness of the stamped form can be simply adapted by the fact that the corresponding Chain link in the incision! the loop b is placed.

Die äsen a und b sind so lang bemessen, daß handelsübliche Bretter h, wie sie auf Baustellen allgemein verwendet werden, in sie eingeschoben werden können.The äsen a and b are so long that standard boards h, as they are generally used on construction sites, can be pushed into them.

Nach dem Einlegen des entsprechenden Kettengliedes in den Haken g ist der etwa noch vorhandene Längenunterschied mit Hilfe von Keilen k auszugleichen, die zwischen das Brett /t und die äsen a, b einzuschlagen sind.After inserting the corresponding chain link in the hook g, any remaining difference in length is to be compensated with the help of wedges k, which are to be struck between the board / t and the aes a, b .

Ebenso leicht, wie sich die Stampfform mit Hilfe der Schließvorrichtung zusammenfügen läßt, kann sie wieder geöffnet werden, denn es sind nur die Keile k zu lösen, worauf durch Aushängen der Kette a aus den Haken g die Verbindung wieder unterbrochen werden kann.Just as easy as the rammed form with the help of the locking device can be joined together, it can be opened again, because there are only the wedges k to solve, whereupon by unhooking the chain a from the hook g the connection again can be interrupted.

Eigenartig ist die Schließvorrichtung besonders deshalb, weil die zum Zusammenhalten der Stampfform no:wendigen Hölzer an keiner Stelle genagel, zu werden brauchen und infolgedessen keinen ernsten Beschädigungen ausgesetzt sind, so daß sie sich beliebig oft verwenden lassen.The locking device is peculiar because the to hold together the rammed form no: agile woods are not nailed at any point will need and as a result are not exposed to serious damage, so that they can be used as often as you like.

Es ist nicht unbedingt erforderlich, daß die Kette d beispielsweise mit der öse a in dauernder Verbindung steht, sondern sie kann auch mit der Öse a in gleicher oder ähnlicher Weise wie mit der öse b i. lösbare Verbindung gebracht werden.It is not absolutely necessary that the chain d, for example with the eyelet a is in permanent connection, but it can also with the eyelet a in the same or a similar way as with the eyelet b i. brought releasable connection will.
