Description

It is a simplified in application and manufacture execution presented a device for tensioning a bricklayer cord.

A Bricklayer cord serves as a guideline for building a house Creation of masonry walls, using for this purpose the mason's cord is stretched along the wall layer to be walled. Waiving other aids is classically the Mason's cord with nails at the ends of the wall to be reinforced Wall layer fastened in the joint. Through this solution can However, the bricklayer string are only partially stretched. Furthermore this requires an already bricked corner at the two ends of the to be walled wall layer, wherein at least on both sides a wall element above the brick wall layer is necessary. For larger ones The string can not be spaced with this solution strained so tightly that it would be possible to achieve a straight horizontal line of the wall layer to be walled. In particular, usually dissolves at high voltage the nail used in the not yet cured joint his anchorage.

To solve this problem shows, among other things, the font DE 296 04 906 U1 a bricklayer cord stopper. In each case a device is attached over the ends of the wall layer to be walled. The device in the form of a bow is placed with the inside over the respective wall corner. To the bow outside a tab is issued, to which the bricklayer cord can be attached by wrapping. Due to the arch shape is carried out when tensioning the bricklayer cord automatically pressing the masonry cord stopper and the bricklayer cord to the wall corner. In this respect, it is possible by this device to be able to prove the bricklayer cord with a larger tension and thereby to ensure a secure location. Slipping or lifting the device is largely excluded. In this respect, it is possible by this device to tension the bricklayer cord in the desired position.

adversely However, with such a design, it is the device each be attached to the ends of the wall layer to be walled got to. This requires the laying of the mason's cord to the respective House corner. This can sometimes be large distances arise, which in turn negatively affect the tension in the mason's cord impact. Furthermore, this device requires both sides of the Presence of another wall element over the two Ends of the wall layer to be walled. Unless one end is not used This device is accessible, thus eliminating completely their possible use.

The problem of being able to realize larger distances in the aforementioned solution without the masonry cord sagging in an inadmissible manner by its own weight, can by a device as described in the document US 2,492,044 disclosed, be resolved. Here, an elastically deformable bracket is used, which can be clamped on the wall element. On the inside in the intersection between the two legs of the support of the bracket on the wall element and the system of the bracket on the wall element, the bricklayer cord can be targeted.

Although it is possible with this solution, the bricklayer cord also over the course of the wall element layer to be walled to be able to lead, the problem remains to be able to tighten the mason's cord safely.

Especially exists with the aforementioned solutions, in particular with the device for tensioning the bricklayer cord, the problem that it is absolutely necessary, above the wall to be walled Pre-wall each another wall element in the corners or to have access. In that sense it is not possible a single wall layer starting from two attached at the ends wall elements to wall. For this the possibility is missing, the bricklayer cord safe and easy to attach.

It It is therefore an object of the present invention to provide a device for To imagine tensioning a bricklayer cord, in which it is easier Way is possible to tension the bricklayer cord, being in this Case only two wall elements at the respective ends of the walled wall situation are available.

Of It is also an object of the present device, the attachment the bricklayer cord so easy to perform that this with a single handle without complicated fastening technology can be fixed. Furthermore, it is required that this device can be produced as inexpensively as possible.

These Task is with a device according to the invention solved according to claim 1.

advantageous Embodiments are subject of the dependent claims.

A device for tensioning a Mason's Cord, which can be placed on a wall element in a running row, has at least one support leg and a plant leg. In this respect, the device with the support leg on the corresponding wall element at the respective end of the wall layer to be walled be hung up. The attachment to the front of the wall element via the plant leg. The typical course of the masonry string along the wall layer to be walled is thus in the direction of the angle edge between the support leg and the plant leg. Necessarily, a device for tensioning a bricklayer cord means to fix the bricklayer cord accordingly.

to inventive design has a Thighs at least a first bridge on, with the first bridge over the angular edge protrudes. To tighten the mason cord this is led around the first jetty. Furthermore, a leg has at least a second bridge on, with the second bridge with his open end of the angular edge is pointing away. The Mason's string can now come from the first jetty above the thigh be guided behind the second bridge. Of special Advantage is the inventive clamping of Mason's string at least behind this jetty.

By the solution according to the invention becomes a very cost-effective device for tensioning the bricklayer cord reached. In particular, the simple production of a simple Material makes the use of appropriate device economical possible. Furthermore, the handling of the invention Device particularly advantageous because it is for tensioning the bricklayer cord is sufficient, the bricklayer cord after laying behind the to stretch the first bridge by hand and behind the second bridge pinch. Thus, even in the state of Technique usual method, the brickwork string several times around tabs to wrap and fasten by means of knots. Thus, too in turn, the bricklayer cord can be detached from the device. In particular, it does not require a cumbersome dexterity to release the thread from the tab or the device. In continuation, it is by the invention Device succeeded in a device for tensioning a bricklayer cord to develop, in which it is not the bricking up of a following Wall element is needed to, for example, a nail in a joint attach or arrange an arch behind the wall corner.

Of the Halt the device according to the invention is the Further significantly improved when substantially parallel to Stop leg a support leg is arranged. By the arrangement of the support leg will be a pull down prevented from resting on the wall.

in the this particular dimension is achieved when the clear distance between the stop leg and the support leg in Essentially the strength of the wall. insofar it can be in this design to no significant inclination the device come on the wall.

Although the strength of the wall as a rule only a few different Has distances and thus it is conceivable for this few number of different wall thicknesses corresponding To keep ready devices, so it is advantageous if in particular the distance between the stop leg and the support leg is variably adjustable. This can be done by the support leg is carried out in two parts. In this case, a first Part of the support leg firmly connected to the plant leg. The adjustable support leg is in turn with the support leg connected. The adjustment of the distance can be done by Example in the adjustable support leg attached a slot becomes, over which the distance can be adjusted, wherein a fastening means is provided on the fixed support leg, which is fixed according to the adjustable support legs. Likewise, it would be conceivable to have a plurality of holes provide in the adjustable support leg, which accordingly the typical strengths of the walls are arranged. Obviously is that for the expert more options consist, the fixed part of the support leg and the adjustable Part of the support leg to connect together. It is also obvious that you can swap the layers and the fixed support leg, which is connected to the plant leg, with the slot or the plurality of holes provides and fix the fastener on the adjustable support leg, which thus rests on the wall, install.

The Attachment of bricklayer cord is especially improved when a third bridge is provided. This is for this purpose with its open end to the angle edge hinweisend arranged or extends over the angle edge out. Accordingly, the bricklayer string behind led to the third bridge.

By the arrangement of first, second and third bridge can in zig-zag course the mason's string are trapped behind the bars. insofar The safe position of bricklayer cord is also higher Voltage guaranteed.

It is obvious that by increasing the number of webs, the possibilities for clamping the mason's cord are increased and thus the safety of the mason's cord against slipping out is improved. Likewise, the number of Einklemmmöglichkeiten at the same time increases the cost of attachment and loosening the bricklayer cord. Furthermore, it is advantageous if a symmetrical shape is chosen in order to use the device for both sides in an identical manner. In this respect, it is advantageous if pairwise first webs are available as well as pairs of second webs and a third web.

The Guiding and laying of mason's cord as well as handling is particularly simplified when the webs on the plant leg are formed.

Favorable Way, the position of the mason's cord is set to the wall element such that the mason's cord is flush with the upper edge of the wall element. As a rule, mason strings have a diameter of about 1.2 mm to 2.0 mm. In this respect, it is advantageous if the bricklayer cord so come to rest that with a diameter of 2 mm the Cord lies below the upper edge of the wall element. This is advantageous, since thus the circulation of a spirit level or the like on the wall element does not lead to a distraction of bricklayer cord thus affecting their usefulness for exact alignment. This is achieved by the distance from the string pad, d. H. the place on the bricklayer's cord after the first jetty rests on the support leg is chosen such that this slightly above the largest diameter is chosen from mason strings, usually be used. Thus, the distance at the support point for To choose support leg with approx. 2.5 mm. Needless to say, it is that the distance is meant perpendicular to the support plane.

In equivalent It is also wise, the distance between the bricklayer cord and the Set wall element in the direction of the system. Advantageously the mason's string comes in front of the wall element with a small distance for lying. Taking into account the diameter of usual brickwork strings is the distance from the point of the first bridge, at the the mason's cord rests, the wall element preferably to a value between 2.5 mm and 5 mm. In this respect, this leads to make sure that the mason's cord runs just in front of the wall element and thus not by the masonry elements or mortar in the joints is deflected, which in turn otherwise the benefits of Would endanger mason's cord. In a simple way this is achieved by the vertical on both sides of the plant leg End is folded and thus the material thickness of the sheet determines the distance with the inner bending radius. Alternatively it is it also possible, of course, to bead in the Impress the plant leg in the direction of the wall element, to reach the necessary distance. In this respect are preferred Embossing elements, z. B. Anlagefalz or beads, in the plant leg brought in.

Especially inexpensive, the device, if this one-piece or in several parts by punching and bending from a flat sheet, especially a stainless steel. It is obvious, that at a fixed distance between stop leg and support leg the entire device can be formed from a single sheet can. Furthermore, it is obvious that to realize a in terms of wall thickness variable adjustable solution the fixed part with plant leg and support leg in one piece can be executed and the adjustable part with adjustable Support leg and support leg also made in one piece can be. This is of course without consideration the necessary fasteners around the adjustable part on fix fixed part.

Especially in the version with an adjustable support leg it is advantageous if two guide collar on the fixed support leg be placed between which the adjustable support leg can be performed. Obviously, that is the management collar also with the same effect on the adjustable support leg can be provided.

To the Clamping a mason's string inevitably requires attachment at the two ends of the mason's cord. In that sense it is obvious that for tensioning a mason cord advantageously a system consisting of two devices according to the invention is used.

The The following figures outline various advantageous embodiments the solution according to the invention.

It demonstrate:

1 a simple embodiment of the device 01 in one-piece design;

2 a variably adjustable embodiment in a modification of the solution 1 ;

3 an alternative embodiment of a device 01 with attached bars;

4 the expression of the webs 05 . 06 . 07 in a solution according to 1 ;

5 an execution of the webs 05 . 06 . 07 in a solution according to 3 ;

6 a section through the attachment of an adjustable support leg 12 with fixed support leg 02 ;

7 another embodiment of the contraption 01 with a reduction in the contour for the masonry cord course;

8th the expression of the webs 05 . 06 . 07 in a solution according to 7 with lateral Anlagefalz 09 ;

9 a sketch of the solution according to 7 in a view from above with lateral Anlagefalz 09 ,

In 1 is a particularly cost-effective embodiment of the device according to the invention 01 presented for tensioning a bricklayer cord. This masonry cord tensioning device 01 , which may be made of a single sheet, is formed from the support leg 02 , the investment thigh 03 and the support leg 04 , It is obvious to a person skilled in the art, such as the Masonry Cord Tensioner 01 comes to rest on the wall element.

The bricklayer cord 10 extends along the angular edge between the support leg 02 and the plant leg 03 , The bricklayer cord 10 runs first behind a first jetty 05a , These first bridges 05a . 05b extend out of the plant leg 03 vertically upwards beyond the angle edge. The height of the bricklayer cord 10 in relation to the wall element is defined by the cord support 08 , The following is the bricklayer cord 10 on the outside (in relation to the wall) of the plant leg 03 followed and behind a second jetty 06a , By shaping the second bridge 06a and the spacing of the lateral gaps between the second web 06a and the surrounding plant thigh 03 becomes the clamp of the bricklayer cord 10 certainly. It is obvious to the expert, like the mason's cord 10 is to be laid to achieve a corresponding clamping. To improve the clamping effect is a third bridge 07 in opposite orientation to the second bridge 06a arranged. It is thus obvious, like the bricklayer cord 10 from the second jetty 06a coming outside the plant leg 03 behind the third jetty 07 can be moved. The symmetrical construction of the Masonry Cord Tensioner 01 offers another second jetty 06b , which further for clamping the masonry cord 10 can be used.

In contrast to 1 where the clear distance between the plant leg 03 and the support leg 04 is fixed, this is in the alternative embodiment in 2 variably adjustable. For this purpose, the support leg extends 02 , which with the plant leg 03 is connected in one piece, not completely over the wall to be walled. On top of this is an adjustable support leg 12 arranged. This is again in one piece with the support leg 04 connected. For fixing the adjustable support leg 12 on the fixed support leg 02 can in simple form a fastener 14 , such as As a screw can be used. For this purpose, it is possible to make the nut as a wing nut, so that it requires no tool to loosen or fasten the screw.

Deviating from the solution 1 show the 3 an embodiment in which the second and third webs 06 . 07 were not stamped out of the sheet, but rather as separate parts on the plant leg 03 were set up. This can be done in a simple form by means of a welding point. In this respect, the second bridge becomes simple 06 and the third jetty 07 as a tab 11 made and on the plant leg 03 placed. The turn mirror-symmetrical arrangement leads in this case to two second webs 06a . 06b and two third bridges 07a . 07b ,

In the 4 is a side view to run from 1 shown. It can be seen as the first, second and third bars 05 . 06 . 07 can be stamped out of the sheet metal. It is therefore possible in a simple embodiment, with a single sheet, the device of the invention 01 manufacture.

Conceivable, however, would also be an embodiment, as in 3 is pictured. This will be in 5 as a side view obvious and shows as a tab 11 with the second bridge 06 and the third jetty 07 on the plant leg 03 is put on. For the connection of the tab 11 to the plant leg 03 There are known to be a variety of possibilities, which are well known to those skilled and he thus an advantageous way, such as. B. spot welding, will select.

In the 6 exemplifies a solution for the connection of a fixed support leg 02 with an adjustable support leg 12 shown. In the illustrated variant of the support leg is 02 below and is stamped in such a way that the center of a lanyard 14 in the form of z. B. a screw can be applied. On both sides are guiding collar 15 placed, the a defined position of the variable support leg 12 secure or prevent its rotation. The variable support leg 12 has a corresponding groove 13 or optionally a plurality of holes positioned to match the wall thicknesses. Shown is a normal mother for fixation. It is obvious that the person skilled in the art will prefer a wing nut, since thus a tool for loosening and fixing is dispensable.

In the 7 becomes an improved solution of the device 01 out 1 shown. In this case, the bricklayer cord is used to define the altitude 10 in addition to the first webs introduced a depression and thus defines a string pad 08 , By determining the distance from the lowest point of the recess, ie the string support 08 to the support leg 02 , the distance is from the bricklayer cord 10 set to the top of the wall element. It is obvious to the person skilled in the art that the exact shaping of the cord support 08 , z. B. straight, oblique, semicircle, is not relevant, if the production is still simply possible.

In the 8th is a side view of the solution 7 outlined. Likewise in 4 can be seen, as the second and third bridges 06 . 07 can be formed from the plant leg. Likewise, this also applies to the first jetty 05 which can be issued as well. In contrast to the previous solutions (cf. 4 ) is the plant leg 03 no longer flat on the wall element. Rather, the wall element comes only on a Anlagefalz 09 with the plant leg 03 in touch. This is mainly used to define a defined distance from the first bridge 05 that is, the place where the mason's cord 10 runs, to the wall element. This ensures that the bricklayer cord 10 runs in front of the wall element and this does not touch.

In the 9 is a top view of the solution 7 outlined. As an exemplary solution for the introduction of embossing elements are the two-sided Anlagefalze 09 to recognize which by flanging the edge of the plant leg 03 can be produced. Furthermore, the course of the bricklayer cord 10 sketched, which consequently occupies a defined distance from the wall element.
