The invention relates to a support sleeve aur assembly and ' Fastening of wooden dowel strips or plates or the like, j at a preselected distance from a load-bearing wall or ceiling surface made of concrete or stone and the use this' carrying sleeve.

They have since then used wooden dowel strips as a component the substructure of wall paneling on the load-bearing Fastening the wall surface require a lining of these strips, as there is a real flatness in the rarest Cases are given and it is also appropriate, e.g. in the interest of maintaining an undisturbed Ventilation between the wall and paneling, the dowel strips also at a distance from the load-bearing Wall mount.

This relining work can be very time consuming the time required can never really be recorded in the context of a preliminary calculation, since this is dependent on too much imponderability.

It is therefore an object of this invention to provide a way to looking for one that saves the tedious relining work on the one hand and the attachment of the dowel strip on the other safely, quickly and plane-parallel to the wall surface, enables.

The support sleeve according to the invention for the assembly of wooden dowel strips or plates or the like. At a preselected distance to the wall is characterized daduroh that this in its front area as a drill collar with alternating following Teeth for pre-cutting in wood and drilling in stone, an inner diameter that is conically outward on the stone side and one that is kept cylindrical on the wood side Inside diameter of a wood-sided flange

as a termination and on the wooden side with coaxially directed longitudinal slots distributed over the circumference ict and that in this sleeve a with .bund equipped, is rotatably supported by this collar in a correspondingly wide annular groove or similar guided bolt, this bolt each with a right-hand thread and, opposite to this, a left-hand thread running up to the collar is provided, the bolt preferably having a left-hand thread on the stone side and a right-hand thread on the wood side, as well as both threaded parts each equipped with a sliding nut secured against rotation are, the stone side nut preferably conical according to the design of the sleeve and the The nut on the wood side is cylindrical, but is designed with expanding teeth guided in the cutouts and

cnua äer bolt itself in its wooden side from the KUlRe stepping shaft has a iuiignut.

The sleeve is expediently manufactured in such a way that that the sleeve is rolled from appropriately profiled strip material.

The J-profile provides that both threads, the Annular groove, the conical part, i.e. all elevations and depressions of the future inner jacket of the sleeve are present on the tape material.

In individual cases it can be useful that the threaded bolt has a center point.

According to the invention, the "sleeve" is used in such a way that that the wooden dowel strip or plate provisionally connected to the viand spacer strips or pieces that will later are removable, put on, the support sleeve over the with a hammer drill connected threaded bolt is passed through the wood into the stone and when the

Back drive and the associated exit of the expanding mandrels from the slots and their engagement in the wood this connects securely with the front face, with the termination of the bilateral expansion processes due to the increase in the torque absorption of the threaded bolts in the area created by the groove Breaking point tears off.

The support sleeve according to the invention thus becomes one when used in the sense according to the invention described above real means of rationalization in interior design.

. The invention is illustrated by way of example by the accompanying drawings}.

'■ Figure 1 shows the approach of the cut support sleeve

ji of the wooden dowel bar, where A is the support sleeve, B the

Dowel strip and C is the concrete wall. On the sketch of the approach of the hammer drill was, as known, waived.

Figure 2 shows the one in the concrete wall and in wood

maintaining a predetermined distance between wall and wood anchored support sleeve.

Figure 3 shows the wood-side part of the support sleeve before the exit of the expanding mandrels.

Figure 4 shows the wood-side part of the support sleeve after the exit of the expanding mandrels.

FIG. 5 shows, on an enlarged scale, the lifting of the expanding mandrels.

ι Figure 6 shows the front part of the support sleeve and

the formation of the drill bit as well as a section in direction A-3 through this part (Fig.6a)

FIG. 7 shows an enlarged view of the formation of the drill bit in part above and a side in view C-D (Fig.7a).

The liärme Z 1 are pre-cutters for the wood, the teeth Z 3 are 3-ear teeth for the stone, the Point Z 2 is the center point for the approach to your wood.

On the stone side, the sleeve 1 advantageously has indented grooves 9 in order to further improve the anchoring in the concrete.

The design of the drill bit 16 has already been written in the information relating to FIG. Also found here for editing Special tools use, with a view to the one-time use of the drill bit normally no tool steel quality is required.

The threaded bolt 5 is connected to a conical nut with a left-hand thread 11 and a nut j carrying the expanding mandrels 13 provided with right-hand thread 12, and as noted, both nuts before rolling in the bolt 5 also on this must be screwed on and brought into the starting position.

The use and puncture is carried out as described, whereby the transmissible torque is determined by the depth of the annular groove 14 acting as a notch groove.
