The invention relates to distancerange holder for fastening the object to having the insulation layer base with the characteristics according to the restrictive part of paragraph 1 of the claims.

For mounting items on walls that are provided with an insulating layer, there is a possibility of anchoring anchoring either the insulating layer or through him completely - in-the-wall as the base. Of course, anchor fixation in the insulating layer, usually considered only in case of small expected loads, ie, for example, for mounting mailboxes, lamps or the like as the insulating layers, for example, polystyrene themselves have only slight stiffness and strength, it is, on the contrary, for heavier items such as awnings, you must mount at the base, i.e. in loadbearing masonry. From the publication EP 1 293 685 B1 it is known that provide distanziali holder, in which the anchor bolt in the form of a set screw with two spaced with the spacing of the threaded sections is fixed with the expansion dowel in the base. This anchor bolt is screwed distantsiruyutsa sleeve to the inner fence. Anchor bolt and distantsiruyutsa sleeve are arranged such that they point away from the base end side distantsiruyutsa sleeve is closed by a layer of insulating mA is Arial or respectively the applied plaster. This end face forms a stop, which can be secured with a fixed object by means of the fastening screw. For this purpose, the fastening screw is screwed into the receiving hole distantsiruyutsa sleeve.

However, the known distanziali holder due to its size is only suitable for medium loads. For high operational effort that can occur, for example, when installing awnings, individual parts would clearly increase.

In particular, distantsiruyutsa sleeve, if it needs to be made of plastic, requires a substantially larger diameter than the anchor bolt. For this purpose, the layer of insulating material, however, has no place.

Therefore, the basis of the invention lies in the challenge to create distanziali holder, which is designed for high loads and can simply be mounted.

In accordance with the invention this task is solved according to the signs of paragraph 1 of the claims. Corresponding to the invention distanziali holder has distanceyou sleeve, equipped with a milling device on its outer perimeter. Thus, by rotating distantsiruyutsa sleeve can greatly expand the original cylindrical hole for anchor bolt in the area of subsequent locations distantsiruyutsa sleeve without having to use the advanced options of the special tool.

In a preferred form of execution distanziali holder in different axial positions can be protected from turning distantsiruyutsa sleeve relative to the anchor rod. When this anchor bolt can roughly be positioned in the axial direction, and the adjustment can be made only through distantsiruyutsa sleeve. As soon as there was alignment can be taken to protect from turning. Due later screwing the fastening screw does not reach the turning and thereby axial movement distantsiruyutsa sleeve relative to the truss rod. For axial adjustment thus is not required cranking anchor bolt, whereby the process of alignment is clearly simplified, in particular, should be used if chemical fixation.

Preferably as protection against turning for anchor bolt is used movable along the axis of the fixture zakanchivaya. It can be done, for example, in the form of a screw without head. Thus, it is particularly simple constructive solution with the standard details. However, fundamentally is also possible to distantsiruyutsa Bush defended himself from turning not zakanchivanii anchor bolt and blades, ribs or the like on the perimeter that are cut into isolation the first layer or the like

Preferably distantsiruyutsa sleeve is conically tapering in the direction of the anchor bolt outer contour. It helps in the expansion distantsiruyutsa sleeve-oriented anchor bolt cylindrical holes in the insulating layer.

As should be used metric mounting screws, distantsiruyutsa sleeve preferably has a receiving hole with thread.

When radially acting forces, which are transferred fixed object on distanceyou nut and anchor bolt fastening comes internally, though only to a minor extent, to bend anchor bolt. Due to this not damaged plaster, if any, distantsiruyutsa sleeve has drawn from the anchor bolt the end of the contraction of the outer diameter, which helps in case of bending of the anchor bolt distantsiruyutsa sleeve in the area of plaster to it does not fit and, thus, damage is excluded.

To the extent possible to reduce a heat bridge between the fixed object and the base, the invention provides distanceyou sleeve and optionally reads the device zakanchivaya run as plastic parts. Because of the need for stability it is generally impossible for anchor bolt. It is within the preferably as a threaded rod, which is anchored at the base by chemical attachment.

The invention is explained below in more detail through the drawings of the example execution.

Figure 1 shows two corresponding to the invention distantsiruyutsa holder in a perspective view with cut and

figure 2 is a detail X of figure 1 in an enlarged view.

Shown in figure 1, the fastening device 1 is used for fastening of the object 2 on the base 3. Based on 3 is an insulating layer 4, for example, of polystyrene, and the layer 5 of plaster. The insulating layer 4 is used for thermal insulation of the Foundation, but due to its small strength he cannot perceive operational efforts, which should be expected on the subject 2. Layer 5 plaster is used to create a visually appealing surface, and to protect against weather influences. Item 2 simplistically represented in the form of corner parts with two mounting holes 6. Thus we can talk about console for mounting of the awning, canopy or similar

To handle the expected operational efforts from the object on the base 3, the mounting device has two relevant invention distantsiruyutsa holder 7. Figure 1 is a top distanziali holder 7 presents without incision, while the lower distanziali holder 7 represent the stations with partial cut. Distantsiruyasj holders 7 contain designed as a threaded rod 8 anchor bolt, which is anchored by means not represented here curable mass in the base 3. On it facing away from the base 3 at the end of the threaded rod 8 is screwed distantsiruyutsa sleeve 9. Using the screw 10 without head as device zakanchivaya distantsiruyutsa sleeve 9 secured from turning. It converts from base 3 to the end face 11 with the help of shims 12 and screws 13 secure the object 2. For a better overview of the washer 12 and the fastening screw 13 on the lower discontinuum the holder 7 is not provided.

Distantsiruyutsa sleeve 9 has an essentially conically tapering towards the base 3 of the external circuit, where a milling device 14 in the form of a stepped, partially passing through the periphery of the teeth. At its converts from the Foundation of the 3 end of the outer contour distantsiruyutsa sleeve 9 has a constriction 15 of the outer diameter and the adjacent end face 11 to the receiving hole 16 for the tool. Inside distantsiruyutsa sleeve 9 is concentrically positioned through hole 17. Facing the base part 3 of the holes 17 provided with a large corresponding to the threaded rod 8 internal thread, and attached here are more fine thread 18 for the formation of the inlet opening 19 to CR is puegnago screw 13.

To create the mounting device 1, first regular perform drill a cylindrical hole through the plaster layer 5 and the insulating layer 4 up to the base 3. In the next step by hammering with rotation distantsiruyutsa sleeve 9 in the plaster layer 5 and the insulating layer 4, a cylindrical hole is expanded to distantsiruyutsa sleeve 9. This may occur, for example, by putting distantsiruyutsa sleeve 9 on electrotorque with power from a battery or other Milling device 14 is used for driving distantsiruyutsa sleeve 9 for such milling grinding layer 5 plaster and insulating layer 4. In the future, arising reception cavity 20 for distancerange holder 7 is cleared, for example, by blowing. The threaded rod 8 is screwed in distanceyou sleeve 9, though - as far as possible, i.e. first, as far as possible is screwed in the screw 10 without head in the direction of the inlet opening 19. This step may occur before the milling operation, i.e. the conical part of the receiving cavity 20 may be formed screwed on distanceyou nut 9 threaded rod.

After cleaning the receiving cavity 20 in this receiving cavity 20 is injected hardenable mass. For the best review of this curable mass in figure 1 are not represented. Then in the receiving cavity 20 wdigets distanziali holder 7, and curing the mass is displaced so that the base part 3 of the threaded rod 8 is completely surrounded and, thus, committed after curing mass. Preferably distanziali holder 7 is pushed so that it is facing away from the base end 11 flush merges with a layer 5 of plaster. After curing mass axial position distantsiruyutsa sleeve 9 on the threaded rod 8 is adjusted by turning. Alignment can mean, for example, that the object 2 is oriented exactly vertically. Because the threaded rod 8 preferably during curing mass as possible is screwed into distanceyou sleeve 9, the aligning means distantsiruyutsa his sleeve facing away from the base 3 by the end of the 11 acts over a layer 5 of plaster. Thus reach that item 2 in any case, is attracted to the layer 5 of plaster, and to distantsiruyutsa sleeve 9, and thus avoid possible damage to the layer 5 of plaster. Thus, defined by the alignment position distantsiruyutsa sleeve 9 relative to the threaded rod 8 is fixed by tightening the screw 10 without head, as he secondlevel threaded rod 8. Further, the object 2 is placed on distantsiruyasj sleeve 9 and is fixed in position by washers 12 and crepe is mportant screws 13.

If high lateral loads fastening comes to bending distantsiruyutsa holders 7, the narrowing of the 15 outer diameter ensures that distantsiruyutsa sleeve 9 does not collide with the layer 5 of plaster and not led thereby to damage. This is important because the layer 5 of plaster, as a rule, is fragile in contrast to the relatively soft insulating layer 4.

To the extent possible to avoid heat flow (so-called "thermal bridge"), as distantsiruyutsa sleeve 9, and the screw 10 without head made of plastic or similar material with low heat conductivity. On the contrary, the threaded rod 8 for reasons of stability made from steel.
