Abstract

The invention is used in particular when breaking off high industrial installations. The device should allow the use of a vibrating steel mass even at Gebehudehoehen that exceed the boom height of suitable basic equipment significantly. According to the invention, a rope to be reeled on a cable drum is guided over a loose roller and deflected in the vertical direction, wherein the loose roller is fixed in height or above the structure part to be broken and a steel mass is fixed to the suspension cable. Another approximately horizontally guided pull rope is attached to the steel mass and can be reeled by a second cable drum. By this the steel mass is brought into oscillation, while by the carrying rope the desired height is determined. The device is used both for producing dividing slots and for destroying the entire building part to be broken off.

Title of the invention:

Vorrich.tu.ng for canceling buildings

Field of application of the invention:

The invention relates to a device for breaking down structures, in particular of high industrial equipment, with a vibrating steel mass.

Characteristic of the known technical solutions:

It is known to smash buildings or structural parts ile by the impact of a ball, pear or wedge-shaped steel mass (see "demolition work" series building research / construction practice Mr · 4-9, Building Academy of the GDR Berlin 1979).

The steel mass is held or lifted by a suitable basic unit, preferably an excavator. In the case of horizontal components, the destruction takes place by dropping the steel mass.

Vertical structures are smashed by swinging the steel mast with a pull rope in boom direction *

This method is characterized by a high labor productivity, low manual labor and. Use of the clearing device during demolition work. A particular disadvantage is the limited use possible with regard to the height of the demolition objects, since the boom height must exceed the demolition height.

Object of the invention:

The aim of the invention is to use the method described when canceling particular high industrial equipment.

Explanation of the essence of the invention:

The invention has for its object to develop a device for breaking off structures, in particular of vertical building parts, which allows the use of a vibrating steel mass even at building heights that exceed the boom height of suitable basic equipment significantly.

According to the invention the object is achieved in that a aufommel auf a cable drum support rope is guided over a loose role and deflected in the vertical direction, which is fixed in height or above the upper edge of a building part to be broken at this or another suitable breakpoint on this vertical support cable set a steel mass. Another approximately horizontally guided pull rope is also attached to the steel mass and can be rewound by a second cable drum »

By tumbling or slackening the support rope, the steel mass is kept at the desired height. The * drumming of the pull rope causes a removal of the steel mass of the abzubrechenden building part. When releasing the pull rope, the steel mass strikes in free fall against the abzubrechende building part and destroys the same at the given location.

By this device buildings of any height can be terminated without restriction with a vibrating steel mass. ¹ The method is particularly suitable for high-level industrial installations, as it consists of a steel construction with wall infill. It is also applicable in combination with z · B »cable breakage by cutting slots required with the vibrating steel mass

be beaten and then the building sections created by these are brought down by means of a cable ·

To simplify the implementation of the loose role and to save the necessary manual work is. It is advantageous to attach them to a tensioning cable so that it is free to move on this. The tensioning cable is stretched parallel to the structural part to be broken off between suitable fixed points.

The necessary cable drums for tumbling the carrying and the traction cable including their drive and controls are mounted on a car zweokmäßigerweise, which is parallel to the building part to be broken terrain or rail and can be anchored in working position.

By these measures, it is possible to beat with the vibrating steel mass both a number of separation slots at intervals, as well .. destroy the entire building part to be broken ·

For utilization of a possibly already located on site construction equipment for clearing the demolition material, such as an excavator, the cable drums of the same can be used for the device according to the invention ·

For example, the rope drum of the winch can be used to whip up the carrying rope and the rope drum can be used to close and open the gripper to unravel the pull rope. »The boom of the excavator is removed for safety reasons.

In the drawings show:

1 is a side view of the device according to the invention

2 is a view of the structure to be demolished showing the feasibility of the device

In Pig. 1 shows a device according to the invention which is actuated by the rope drums of an excavator ·

At the top of a building part to be broken off 1. a loose roll 2 is attached with a rope sling. About this loose roller 2, a support cable 3 is guided and deflected in the vertical direction. A steel mass 5 · Sin is approximately horizontally guided on the supporting cable 3 that can be rewound through the cable drum of the windmill of the excavator 6 is also attached to the steel mass 5 and through the cable drum for closing and opening the gripper of the excavator 4 can be rewound ·. The boom 7 is deposited during demolition work.

With the pull rope 6, the steel mass 5 is subtracted from the aborted building part 1 and then beaten again against this ·. , ·

The change in the height of the steel mass 5 takes place by the tumbling of the supporting cable 3 ·

Bs is useful to beat dividing slots from bottom to top to prevent wedging of the demolition material

In Pig. 2 is shown a further embodiment,

Here, the loose roll 2 is attached to a tensioning cable 8 so that it is guided freely movable along the same · The tensioning cable 8 (not shown) between suitable impact points parallel to the abbrucht building part 1 stretched.
