Abstract

The upper reinforcement is inserted in concrete ceilings, for static purposes, esp. in high-rise buildings, and requires reliable spacing from the lower reinforcement. The member has a triangular cross-sectioned combination of one top rod and two bottom rods interconnected by diagonal struts. The bottom ones lie on the lower reinforcement without touching the ceiling form. The top reinforcement rests on the upper rod, maintaining the required interval between the two reinforcing sets. The diagonal struts may be welded to the upper and lower rods. Spacers of various heights and wire thicknesses are practicable, and remain firmly in position, without causing rust spots or unevennesses in visible concrete.

Description

Abstandhalter für obere BewehrungSpacer for upper reinforcement

Stahlbetondecken und ähnliche Deckenkonstruktionen, insbesondere für den Hochbau, erhalten im Bereich der Stützenmomente, sofern sie kontinuierlich ausgebildet sind, aus statischen Gründen eine obere Bewehrung. Um den Abstand der oberen Bewehrung zur unteren Bewehrung gewährleisten zu können, werden sogenannte Abstandhalter verwendet, die in verschiedenen Ausführungen bekannt sind; so z.B. als Hocker aus Draht oder Kunststoff, die auf die Schalung gestellt, die obere Bewehrung tragen und somit den Abstand, bedingt durch ihre Höhe zur unteren Bewehrung, bestimmen. Diese Hocker und ähnliche Abstandhalter haben den Nachteil, daß sie labil sind, sich während der Bewehrungsarbeiten verschieben oder umfallen, bzw. durch Darauftreten sich zusammendrücken lassen. Außerdem stehen diese Abstandhalter unmittelbar auf der Schalung und verursachen, sofern die Füße nicht ausreichend isoliert sind, an der Unterseite der Decke Rostflecke. Bei Sichtbeton entstehen außerdem unansehnliche Unebenheiten bzw. Nester. Die Erfindung vermeidet alle diese Nachteile.Reinforced concrete ceilings and similar ceiling structures, especially for the building construction, preserved in the area of the column moments, provided they are continuous are formed, an upper reinforcement for static reasons. To ensure the distance between the upper reinforcement and the lower reinforcement to be able to, so-called spacers are used, which are in different Designs are known; For example, as stools made of wire or plastic, which are placed on the formwork, carry the upper reinforcement and thus determine the distance to the lower reinforcement due to its height. These stools and similar spacers have the disadvantage that they are unstable, shift during reinforcement work or fall over or let yourself be squeezed by stepping on it. aside from that These spacers stand directly on the formwork and, if the feet are not sufficiently insulated, cause the underside of the Ceiling rust stains. In the case of exposed concrete, unsightly bumps or nests also arise. The invention avoids all of these disadvantages.

Die Erfindung betrifft Abstandhalter für obere Bewehrung, vorzugsweise aus Draht gefertigt. Es ist eine Dreieck-Konstruktion von beliebiger Länge, die aus einem oberen stab und zwei unteren Stäben gebildet ist. Die Stäbe sind miteinander durch Diagonalen verbunden. Die unteren Fußpunkte der Diagonalen sind nach außen abgebogen. An der Unterseite dieser Abbiegungen sind die genannten unteren Stäbe befestigt. Der obere Stab des Abstandhalters dient zur Auflagerung der oberen Bewehrung. Mit den beiden Unterstäben wird der Abstandhalter auf die untere Bewehrung gestellt, wobei die Dreieck-Konstruktion dieses Halters das Standvermögen günstig beeinflußt. Indem der Abstandhalter auf die untere Bewehrung gestellt wird, kommt er mit der Schalung in keiner Weise in Berührung.The invention relates to spacers for upper reinforcement, preferably made of wire. It is a triangular construction of any length, made up of an upper rod and two lower rods. The bars are connected to each other by diagonals. The lower base points of the diagonals are bent outwards. At the bottom of this Bends are attached to said lower bars. The upper bar of the spacer is used to support the upper reinforcement. With the the spacer is placed on the lower reinforcement on both lower bars, the triangular construction of this holder has a favorable effect on the stability. By placing the spacer on the lower reinforcement it does not come into contact with the formwork in any way.

Die Abstandhalter können in verschiedenen Höhen und verschiedenen Drahtstärken gefertigt werden. Durch Anrödeln an die Unter- und Oberbewehrung ergibt sich ein einwandfreier Halt und eine unverschiebliche Lage d^r Abstandhalter. Weder durch Rütteln beim Verdichten des Betons, noch dura Begehen während der Bewehrungsarbeiten werden diese in ihrer Position verändert.The spacers can be manufactured in different heights and different wire thicknesses. By bolting to the lower and upper reinforcement, a perfect hold and an immovable position of the spacer result. These are not changed in their position either by shaking when compacting the concrete or by walking on them during the reinforcement work.

Im folgenden wird die Erfindung anhand einer, lediglich ein Ausführungsbeispiel darstellenden Zeichnung erläutert:In the following the invention is based on, only one embodiment Illustrative drawing explained:

Es zeigen:Show it:

Figur 1 den Abstandhalter für obere Bewehrung in der Seitenansicht; Figur 2 den Abstandhalter für obere Bewehrung in der Vorderansicht.FIG. 1 shows the spacer for the upper reinforcement in a side view; Figure 2 shows the spacer for upper reinforcement in the front view.

Der in den Figuren 1 und 2 dargestellte Abstandhalter für obere Bewehrun' besteht aus einem oberen Stab 1, vorzugsweise als Rundstab gewählt, den unteren Stäben 2 und den Diagonalen 3. Der obere Stab 1 ist mit den Diagonalen 3, die sich seitlich an diesem anlegen, kraftschlüssig, z.B. durch Schweißen, verbunden. Die unteren Stäbe 2 sind mit den Diagonalen [ ebenfalls biegesteif, z.B. durch Schweißen, verbunden. Der Abstandhalter ruht mit den Stäben 2 unmittelbar auf die untere Bewehrung 5. Die obere Bewehrung 4 liegt ebenfalls unmittelbar auf den oberen Stab 1 des Abstandhalters. Die unteren Fußpunkte der Diagonalen 3 sind leicht nach außen abgebogen.The spacer for upper reinforcement shown in Figures 1 and 2 consists of an upper rod 1, preferably chosen as a round rod, the lower rods 2 and the diagonals 3. The upper rod 1 is with the diagonals 3, which are laterally applied to this , non-positively connected, for example by welding. The lower bars 2 are connected to the diagonals [ also in a rigid manner, for example by welding. The spacer rests with the bars 2 directly on the lower reinforcement 5. The upper reinforcement 4 also rests directly on the upper bar 1 of the spacer. The lower base points of the diagonals 3 are bent slightly outwards.
