Abstract

Mortar-applying device according to patent 100 54 899, characterized in that the circumferential, the stones (3) not touching mortar roller (6) is driven by a motor (11).

Description

The present invention relates to a further development of the mortar applicator according to the German patent 100 54 899 of the applicant. For applying thin-bed mortar on one side of a plurality of juxtaposed stones, in particular high-hole stones, the device is moved over the stones. Under Dünnbettmörtel is also Schmalfugenmörtel according to the German patent DE 42 18 143 C1 Understood.

In the parent application will become a mortar applicator with a mortar roller described that a mortar strip a predetermined thickness and width without reinforcing insert manufactures, the subsequently like a rug over the stones are laid.

there is the mortar application roller, which itself does not touch the stones to be coated, through a drive roller arranged under the mortar container or corresponding wheels driven. If a suitable ratio is selected, the conveying speed is the same the mortar roller exactly the speed of the over the stones moved device, so that through the slit-shaped discharge opening in the rear housing wall of the Device exactly the amount of mortar leaking, which is used to fill the stones with a closed layer of mortar is necessary. When the drive roller stops, the mortar roller is stationary and it will not mortar more through the discharge opening promoted. This has u.a. the disadvantage that, for example, the last piece a stone row to be coated not with this device can be coated when the drive roller no longer contact has to be coated stones and thus also the mortar strip producing mortar roller stationary. The same is true in front of a pillar or a wall, when the applicator bumps against it. But not only in the wall end areas Such a mechanical coating is not possible, but also during construction Narrow pillar, because under certain circumstances, the drive roller at any Place has contact with the underlying stones.

Because the device described in German Patent 100 54 899 while of the application process rests only on the drive roller and therefore and can sway, the must the device operator during the entire application process ensure, that the Device does not tip. But even a slight swaying back and forth the device can cause that the only one or a few millimeters thick mortar strip between the discharge and the overlay on the stones or even tears off or gets too fat.

Of the Invention is based on the object, a mortar application device for disposal to provide, with which the mentioned disadvantages are avoided. Especially should also be the coating in Mauerendbereich or in front of pillars allows simplifies the handling of the device on the site and while the application effort required effort can be reduced.

The solution The object of the invention consists in a development of Subject of the German patent "Device and method for the application of thin bed mortar "with the number 100 54 899 of Tubag Trass-, Zement- und Steinwerke GmbH. Thus is also the description of this patent application complete disclosure of the present patent application, even if not expressly stated hereinafter Reference is made.

at the inventive Device is according to a mortar application device the parent application, in which the stones normally not touching mortar application roller a motor is driven. As a result, the mortar roller moves independently from a drive roller. But with the motor drive, the mortar roller can even in otherwise inaccessible Areas the desired mortar strip through the discharge opening transport to the stones.

Instead of the mortar roller To drive directly with a motor, this can also drive roller drive, which in turn drives the mortar roller. Thereby can the mortar applicator as usual hand over the stones are pulled, the engine is disengaged, and only in the Mauerendbereich is by briefly pressing the Motors also the last piece with mortar coated. It is also conceivable that the engine during the the entire driving operation drives the drive wheel, whereby the Operation and handling of the application device on the construction site would be simplified.

Of the Engine is appropriate one electric motor. He can, for example, by batteries, accumulators (Rechargeable batteries) or a power cord. The usage of batteries has the advantage that these can be exchanged and recharged if necessary. there is in particular the use of commercially available batteries, for example the usual on construction sites Akkubohrer etc. thought.

in the The following is the invention by way of example with reference to a drawing clarifies:

1 schematically shows a variant of the mortar application device according to the invention during the application

In 1 is a part of a wall with three vertically placed bricks 3 to be seen preparing for the next stone shift. For this purpose, a Dünnbettmörtelschicht 2 placed on their surface.

The mortar application device serves this purpose 1 , It consists essentially of a funnel-shaped container in side view. The device 1 has a rectangular filling opening at the top 5 for mortar 2 on. It has a width that is essentially the width B of the stones 3 equivalent. Their length L and this width define the size of the filling opening 5 , Because when laying the mortar carpet 2 usually already the string is stretched for the alignment of the next higher row of stones and the upper edge of the mortar container could collide, it may be appropriate that the width of the mortar applicator 1 is slightly smaller near the upper edge, for example 2 to 4 cm smaller than the width B of the stones. For the same reasons, the overall height of the mortar application device 1 be kept below 25 cm. In particular, when at the construction site next to the mortar application device according to the parent application still a smaller mortar application device 1 according to the invention is also provided in front of walls or pillars for covering short pieces, this may be smaller and lighter and it is sufficient that they have a mortar strip 2 from only 12 to 15 cm wide can hang up. In general, the mortar application device according to the invention 1 when covering the said short pieces also transversely to the wall, ie transversely to the row of stones moved.

In the lateral view through the device 1 according to 1 is the arrangement of the mortar roller 6 , the adjusting plate 9 and the mortar strip 2 from her detaching wire 8th to recognize. Will the with thin-bed mortar 2 filled device 1 moved in the travel direction s, is automatically the drive wheel 7 powered by the gear wheels a and b the mortar roller 6 drives. The conveying speed of the mortar roller 6 exactly matches the speed of the stones 3 moving device 1 , so that through the gap-shaped discharge opening 4 Exactly the amount of mortar leaks on the stones 3 to form a closed layer is necessary.

Comes the device 1 during the application process in the end region of the stone row, in which the drive roller 7 the underlying stones 3 no longer touched, so takes over an electrically powered engine 11 , which can be started by the worker at the push of a button, either directly the further drive of the mortar roller 6 or the drive roller 7 , which then turn the mortar roller 6 emotional. The motor 11 drives via a gear c, the gear b and thus the drive roller 7 at.
