DE202007002564U1 - Device for holding and pulling up improperly seated or defective boundary stones, in particular curbs - Google Patents

Abstract

contraption for holding and pulling up improperly seated or damaged boundary stones, especially curbs. Characterized by a screw Clamping and supporting device.

Description

The The invention relates to a stone lifter which is lowered for lifting Curbs u. Leistensteinen serves.

With the device allows a man without effort heavy stones, such as. Raise curbs.

was standing the technology is called curb tongs and scissors grab, for lifting and handling two people, or heavy equipment required do.

The Invention consists of two Schraubzangen invention, the Curb from above and hold two threaded rods, and one Frame with four feet for Support on Ground. Two of the four feet are height adjustable arranged, e.g. to compensate for the height difference between the street and the sidewalk.

About the inclined plane of the thread, the curb is made without any effort pulled the floor.

About the Framework, the whole is supported on the ground.

to Repair of individual curbs, the raised curb does not need be lifted to the side.

Of the Curb remains suspended in its position in the air. While under a new concrete bed is prepared for the stone. So raised curbs, then can be lowered again. Should the concrete bed be too deep or too high accomplished its stone can easily be raised again.

The Concrete bed can also be very fluid accomplished be, because the stone can be up to the hardening of the concrete at the device hang stay.

To deep-seated curbs can even only up to the correct height be raised and then by means of bores from the side to the Cavity to be placed under the curb, with a hardening Liquid over the Bores are filled. After curing the lifting device can be removed.

The four feet of the frame can also as wheels accomplished it will be a shift after lifting the stone longitudinal of the stone.

Of the Advantage of the invention is a very cost curb repair execution to lowered curbs or groin stones - on original Bring height - will only a person needed.

It will not be a heavy device need like excavator or compressor.

The Invention will be explained in more detail below using an exemplary embodiment.

That with 1 and 2 illustrated tubular frame frame according to the invention 1 is U-shaped, with two U-shaped bent tubes with the ends 8th and 5 resting on the ground. The two pipes 1 are at the top center with two parallel square tubes 9 connected. The distance between the two square tubes 9 is sized so that the threaded rods with hooks 2 put through and can be moved to any position.

The two height-adjustable outriggers 5 are needed to compensate for the difference in height between the street and sidewalk, so that the device can be placed approximately dare. With 3 illustrated screw clamps 3 are at the outer upper ends of the curb to be lifted 4 set and with the screws 17 tight.

In the screw-jaw gripper components 14 and 11 There are several holes 12 to customize the span individually.

The threaded rods with hooks 2 are preceded from above with the hook side - nuts 7 and slices 18 are already at the top of the thread - through the space between the parallel square tubes 9 put and with the hooks in the suspension eyes 13 the screw tongs gripper 3 hooked.

To raise the curb 4 be the nuts 7 , with the help of the socket wrench 10 , alternately dressed. That's how it gets in the joints 19 still stuck curb without any effort, with the help of the inclined plane of the thread, raised.

The raised curb 4 Can remain in the raised state for the preparation of the new mortar bed.

In execution, as in 5 and 6 shown with wheels 20 on the outriggers 5 can the raised curb 4 be moved in the longitudinal direction of the curb to create a more accessible work space.
