Description

The invention relates to an assembly device for assembling at least one load-bearing element according to the preamble of claim 1 and an assembly method for assembling at least one load-bearing element according to claim 9.

From the DE 298 15 948 U1 a nailing iron is known which can be used as a mounting device, the nailing iron comprising a lever with a first free end and a second free end, the first free end for attaching the mounting device formed by the lever to a stationary component and for transmitting a counterforce is provided on the stationary component and wherein the second free end is provided for actuating the assembly device so that, for example, a nail can be pressed into the component with the nail iron when the nail iron is attached to the component and placed on the nail. The disadvantage of such a mounting device is that the direction of the pressing force changes during the pressing and the nail is therefore not pressed in in a straight line.

Furthermore, from the U.S. 2,322,464 A a pulling device is known which comprises a hand lever, a support element pendulum attached to a free end of the hand lever and a pull rod pendulum attached to the hand lever between a handle and the support and having opposing folding wings.

From the U.S. 2,889,618 A a socket extractor is known which comprises a base plate, a lever mechanism and an L-shaped wedge connected to the lever mechanism for extracting a socket.

From the DE 74 18 080 U A tool for opening a motor vehicle from the inside, in the form of a crowbar, is known, the tool essentially having a Z-shape, the one end section being shorter than the other end section and the two end sections being opposite to the other cross sections Ends are drawn down.

Finally from the U.S. 5,165,312 A a spreading tool known to move the semicircular shoes of a drum brake away from each other.

It is the object of the invention to propose an assembly device and an assembly method which is optimized for the pressing in of a load-bearing element and in particular generates a pressing force which largely maintains its direction during the pressing-in process.

Based on the features of the preamble of claim 1, this object is achieved by the characterizing features of claim 1 or by the features of claim 9. Advantageous and expedient developments are specified in the subclaims.

The assembly device according to the invention for assembling at least one load-bearing element in a respective recess of a sleeve, which is used to manufacture a concrete manhole ring and which is designed in particular as a concrete manhole ring load-bearing element assembly device, comprises a lever with a first free end and a second free end, the The first free end is provided for attaching the assembly device to a stationary component and for transmitting a counterforce to the stationary component, and the second free end is provided for actuating the assembly device, the assembly device further comprising a pressure piece and a hinge device, the pressure piece between the two free ends is connected to the lever via the hinge device and wherein the pressure piece is pivotable about an axis of rotation relative to the lever. With such a mounting device, it is possible to use the pressure piece by actuating the lever at its second, free end with manual force or actuating force and when the first free end of the lever is supported on a component with a counterforce G to exert a force that remains constant in its direction when pivoting the lever around an articulation area. Accordingly, the load-bearing element can be pressed into the recess of the sleeve in a straight line, without tilting and gently. The essence of the invention is thus an assembly device in which the lever and the pressure piece are decoupled from one another by a swivel joint in order to deflect the force exerted by the lever.

Furthermore, the invention provides for the first free end of the lever of the assembly device to be designed as a suspension device and in particular as a hook-shaped claw, with one end portion of the suspension device resting against an underside of the sleeve during the assembly process. This enables the assembly device to be attached and detached from the socket quickly and easily.

The invention also provides for the pressure piece of the assembly device to be adapted to a surface geometry of the load-bearing element that comes into contact with the pressure piece in such a way that the pressure piece is pressed against a Middle area, a left edge area and a right edge area of the load-bearing element in particular rests flat. In this case, it is provided in particular to equip the pressure piece with two pressing jaws with pressing surfaces, which are arranged at a distance from one another, and a holding-down section, which is arranged between the pressing jaws, with a holding-down surface. With a pressure piece adapted in this way to the load-bearing element made of plastic, it is possible to press the load-bearing element into the recess of the sleeve with a high pressing force, for example, without the latter bending or bulging in its central area.

The invention provides for the pressing surfaces of the pressing jaws to be arranged in a first plane, for the holding-down surface of the holding-down section to be arranged in a second plane and for the first plane and the second plane to be aligned in particular parallel to one another. In addition, the invention provides for the load-bearing element, which can be pressed into the sleeve forming the stationary component by means of the assembly device, with a striking surface divided by a web, the two partial surfaces of the striking surface being in a common third plane and the web being orthogonal to the The third level has a height which corresponds to a distance at which the first and second levels are apart, the load-bearing element being uniformly pressed into the recess with a pressing force due to the hold-down section resting on the web, avoiding bulging of the pressure piece of the assembly device the sleeve can be pressed in. This makes it possible to press in the load-bearing element with its web arranged between two striking surfaces with a force distributed over a longitudinal extension.

According to the invention, the pressure piece forms a bridge with its pressing jaws and its hold-down section, the bridge forming a centering device which is aligned on a web of the load-bearing element. Such a shape ensures intuitive use of the assembly device.

According to a first embodiment variant, it is provided that the axis of rotation - viewed in the plan view of the assembly device - be aligned transversely to a longitudinal axis of the lever. As a result, the second free end of the lever, at which the user actuates the assembly device to press in the load-bearing element, is maximally removed from the sleeve, so that the user has a large amount of freedom of movement to actuate the assembly device.

According to a second embodiment variant, it is provided that the axis of rotation - viewed in the plan view of the assembly device - obliquely to a longitudinal axis of the lever and in particular at an angle β to be aligned from 30 ° to 70 °. This makes it possible to use the assembly device even in confined spaces, since the lever protrudes less from the sleeve in the radial direction than the lever of an assembly device in which the axis of rotation - viewed in the plan view of the assembly device - transversely to a longitudinal axis of the lever is aligned.

An assembly method according to the invention for assembling at least one load-bearing element in each recess of a sleeve with the assembly device according to the invention, in which the sleeve is used to produce a concrete manhole ring and which is in particular a load-bearing element assembly method, comprises the steps of inserting the load-bearing element into the recess of the sleeve , hooking the assembly device with its claw into an edge web of the sleeve, positioning the pressure piece over the load-bearing element inserted into the recess, attaching the pressure piece to the load-bearing element, pressing down the pressure piece by means of the lever onto the load-bearing element and thereby pressing in the load-bearing element into the recess of the sleeve, the depression taking place by pivoting the lever around a pivot area formed by the claw with the sleeve, and finally the step of pivoting away the Mont storage device around the articulation area and unhooking of the assembly device from the sleeve. This process enables a repetitive and professional pressing in of load-bearing elements with simple steps and thus an increase in product quality.

In the as yet unpublished German patent application 10 2011 018 623.9 The applicant describes a load balancing element and its use, which can be used in particular by applying the assembly device described here as an invention and by applying the assembly method described here as an invention.
