Description

The The invention relates to an insulating anchor for a with an outer layer like insulation layer provided building.

Out Environmental and energy reasons there is a desire for buildings as far as possible thermal bridges too avoid. Often However, these are unavoidable when elements such as awnings, Shutters, Advertising signs, pipes or air conditioning units are to be attached.

From The company Fischer Waldachtal, Germany, is a distance mounting device for awnings distributed, the screwed into a building threaded rod that covers over one in an insulating layer anchorable cause a thermal separation and made of plastic existing cone is connected. From the cone goes a set screw out, over the awning is anchored. The threaded rod and the threaded pin are over one narrow web in the cone separated, however, the desired thermal insulation not sure. Due to the short length of the cone and its anchoring in the insulating layer it requires an oversizing of the Threaded rod in order to absorb transverse loads to a sufficient extent can.

Of the present invention is based on the object, a Isolierverankerung in such a way that to the required extent a thermal separation guaranteed and thus avoid unwanted thermal bridges become. This is a decoupled attachment of objects each Kind on walls, Floors and Ceilings of a building allows be whose surface by soft or soft pressure-resistant materials such. B. polystyrene foam or mineral wool are thermally insulated.

to solution the object an insulating anchor is proposed, the one made of plastic and with an anchoring area forming first area anchored in the building and at least partially sleeve-like trained cylinder element comprises, the other end as a receptacle for a made of metal fastener is formed, wherein the Recording is spaced from the anchoring area. It is in particular provided that the cylinder element a dowel with in its longitudinal axis extending passage opening is and the anchoring area separated from the recording by an air column is, in particular, a length between 20 mm and 200 mm, preferably 40 mm and 150 mm. Of course they are Not measurements protection restrictive to see. So can z. B. at very large Insulation thicknesses Cylinder elements are used, the air columns of more than 200 mm.

By a related Insulating anchoring in masonry, concrete or other Building materials can be anchored Loads are absorbed in each load direction, whereby through the Design of the preferably designed as a dowel cylinder element a thermal decoupling between the building, so the masonry, the Concrete or other building materials and the object to be fastened and the outside environment of the fastening element takes place. Thus, thermal bridges are on an isolated building like on walls, Floors or Ceilings avoided or largely reduced.

The Insulating anchor consists of an anchoring part, which in the anchored supporting structure is and one in the recording pending Section that is inside the outer layer like the insulating layer extends. In this case, the insulating anchor used in such a way in the building be that outside End of the insulating anchorage, d. H. of the cylinder element with outer surface of outer layer Aligns or over the outer surface protrudes.

Especially then, if the cylinder element is a dowel body, is a large volume filled with air Cavity available, the one you want thermal insulation between the possibly a metallic Component having anchoring area, such. B. the insulating anchorage in the building anchoring means such as screw or wedge or cone, and that of the recording recorded fastener as existing metal Screw or pin ensures.

alternative it is possible, form the cylinder element with the exception of the inclusion as a solid body. In this case, the anchoring of the Isolieranankerung not the Property of a dowel but used by the anchoring area of the cylinder element protrude anchoring means or an external thread is provided the above one in the building curing Material like mortar or glue the one you want Anchoring ensures.

In particular, it is provided that the cylinder element is a sleeve member with along its longitudinal axis extending through opening, that in the anchoring region of the cylinder element an expansion anchor is arranged and that in the expansion anchor engages a head having a screw whose head on a running at a distance from the receptacle federal rests in the cylinder element. As a result, the possibility ge create that the expansion element (expansion cone) tightened when turning the screw and thus the sleeve member is spread in the form of a dowel, so that the desired anchoring takes place in the building.

The sleeve member but it can also follow a classic construction of a dowel, so that in the anchoring area a head having screw is arranged, wherein the head rests on a collar, depending on from the setting depth of Zylin derelementes z. B. in the cutting plane between building and isolation and independent thereof runs at a distance from the receptacle.

alternative can be mentioned that Cylinder element with the exception of the inclusion as a solid body with Anchoring means projecting in the anchoring area, such as projections or external thread be educated. A related Construction provides good insulation. At the same time takes place Anchoring by the anchoring area surrounding and hardenable Materials such as glue or mortar.

A another possibility the anchoring of the cylinder element is that in the Through opening a spreading of the sleeve member causing Wedge runs, which is driven in the anchoring part. This is done until in the area of the masonry.

It there is also the possibility that the anchoring area is surrounded by a sieve sleeve, wherein between the sieve sleeve and the anchoring area a curing material such as glue or Mortar over in the anchoring area existing openings Pressed under pressure. A related construction is included Anchorages used in hollow chamber materials such as hollow perforated bricks.

Around to ensure, that the required air column between the anchoring of the cylinder element causing elements and adhered to the outgoing from the attachment fastener is a continuing education, that the admission floor-side limited by a cross section of the passage opening reducing federal government is that can not be overcome by the fastener.

A method for attaching a component such as awning, shutter, advertising sign, pipe or air conditioning unit to a building with an outer layer of soft or soft and pressure-resistant material such as insulation or plaster layer using a Isolierverankerung previously described type is characterized by the process steps:

• - Producing a layer passing through and extending into the building bore,
• - Inserting and anchoring the cylinder element and
• - Screwing the fastener into the receptacle for securing the device.

Especially is provided that initially inserted into the bore a sieve sleeve is then filled with fixing material such as glue or mortar in the sieve sleeve and after all the cylinder element is used. This application applies especially for Hollow chamber construction materials such as hollow perforated bricks o. Ä.

Also it is possible, in the bore a cylindrical element with through holes and with existing in the anchoring area openings to then Fixing material such as glue or mortar over the Through opening under pressure.

One Another proposal is that in the hole first a perforated sleeve and then introducing a fixing material and then the cylinder element with projecting anchoring means present in the anchoring area is used. in this regard activities especially when used in hollow chamber building materials for use.

A possibility for anchoring the cylinder element provides that in the bore that the passage opening having cylindrical member is used and then a spreading by driving a spreading such as wedges. This can z. B. made of plastic, wood or metal.

alternative the invention provides that the cylinder element having the passage opening with the anchoring area limiting collar in the hole can be used so that the federal government in the outside of the building spanned level. Incidentally, the hangs Course of the Federal Government to the building exterior of the setting depth of the cylinder element.

It there is also the possibility a screw in the passage opening for spreading the cylinder element screw in, with the head of the screw on the collar to come to rest. In this case, the screw with a anchoring area longitudinally displaceable in the passage opening positionable conical expansion element cooperate, so that tightened by turning the screw the wedge element and thus the cylinder body is spread.

Further Details, advantages and features of the invention do not arise only from the claims, the characteristics to be taken from them - individually and / or in combination - but also from the description below of the drawing to be taken preferred embodiments.

It demonstrate:

1 a first embodiment of an insulating anchor,

2 a second embodiment of an insulating anchor,

3 a third embodiment of an insulating anchor,

4 A fourth embodiment of an insulating anchor,

5 a fifth embodiment of an insulating anchor and

6 a sixth embodiment of an insulating anchor.

In The figures are purely exemplary of six different embodiments represented by insulating anchors that emanate from a building and one the building covering layer such as insulation layer push through. The insulating anchorage basically has one made of plastic cylinder body on which the function a dowel can, but does not have to. In this case, the cylinder body has a in the longitudinal direction extending passage opening on, wherein the running within the building area spreadable is. Alternatively, the cylinder body except one outside within the insulating layer extending portion may be formed as a solid body.

Independent of this is formed by the invention Insulating anchor ensures that a thermal decoupling between an outside on the building to be attached object and anchoring in the building itself he follows.

at The following descriptions of the various embodiments of insulating anchors are basically the same elements with the same Provided with reference numerals.

A first embodiment of an insulating anchorage 14 has a plastic dowel body 16 up into a hole 18 is used, both in a building 10 as well as in an insulating layer 12 runs. The dowel body 16 has a covenant 20 on, through which the dowel body 16 in an anchoring section 22 and an outer section 24 is divided.

This should be the anchoring section 22 completely within the building 10 extend. Thus, preferably the federal government runs 20 in the sectional plane between building structure 10 and insulating layer 12 , Ultimately, however, depends on the course of the federal government 20 from the setting depth of the anchoring element 14 from.

In the exemplary embodiment, the federal government 20 in one of the outer surface of the building 10 spanned plane and the free end face or the end edge 36 of the outer section 24 goes flush in the outer surface 28 the insulating layer 12 above. However, this is also not a mandatory feature. Rather, the frontal area 26 also over the outer surface 28 protrude.

The dowel element 16 is by means of a cone 30 (Spreizelement), located in the expandable anchoring section 22 is anchored. The cone 30 this works with a screw 32 together, whose head 34 on the fret 20 rests. By turning the screw 32 becomes the cone 30 attracted and thus the dowel element 16 spread to its anchorage. Above the covenant 20 and the head 34 the screw 32 there is an air column causing the desired insulation 36 on the outside of a receptacle 38 is limited, in which a fastener such as screw for attaching an object such as awning, advertising media, pipe or air conditioner is screwed. It is preferably provided that the recording 38 is limited by a collar, not shown, which ensures that the fastener not in the through hole 40 the dowel element or body 16 can be screwed in that makes contact with the screw 32 he follows.

This in 2 illustrated embodiment of an insulating anchorage 42 also has a dowel body made of plastic 16 on, directly by means of the screw 32 in its mooring area 22 spread and thus in the masonry 10 anchored, without a spreader is used. When anchored, the head can 34 the screw 32 likewise on the dividing line between the building 10 and the insulating layer 12 run, provided that the federation 34 located in the area of the dividing line.

Depending on the setting depth and length of the dowel element 16 runs the federal government 34 within the structure 10 , in the area of the dividing line or in the insulating layer 12 ,

An insulating anchor 44 to 3 consists of a plastic sleeve body 46 with through hole 48 as well as in the anchoring area 22 existing openings 50 . 52 , over which the passage opening 48 introduced under pressure fixing material such as adhesive or mortar is durchdrückbar to the sleeve body 46 to anchor. The hole 18 can be surrounded with a sieve sleeve, especially if an insert should be made in perforated bricks. In the front area, the sleeve body 46 a required for screwing a fastener recording 54 on, over a covenant 55 into the through hole 48 passes. The Bund 55 thus serves as a stop for the fastener.

Is according to the previously described embodiments in the building 10 designed to be anchored cylinder element as a sleeve body, so it is also possible, the cylinder body with the exception of a recording 56 form for a fastener as a solid material, such as the Isolierverankerung 58 in 4 shows. To the insulating anchorage 58 in the masonry 10 anchor the anchorage area 22 an external thread or other outwardly projecting projections, which are embedded in a hardening fixing agent such as adhesive or mortar. In addition, one recognizes that the anchoring area 22 from a sieve sleeve 60 surrounded as the insulating anchorage 58 in an area of the building 10 is used, the z. B. consists of perforated bricks.

An insulating anchor 62 according to 5 has an expandable sleeve body 64 and the function of a dowel, wherein the anchoring area 22 by means of a through opening 66 driven spreading element such as wedge or cone 68 is spread. In the outer end area 24 is also a recording 70 intended for a fastener. The spreading element 68 can be made of any suitable material such as plastic, metal or wood.

To the spreader 68 It should be noted that this is preferably formed conical or truncated pyramidal, to a spreading effect in the cylindrical through hole 66 to achieve. The pitch angle of the cone or truncated pyramid is extremely low.

From solid material exists after the 6 a further embodiment of an insulating anchor 72 in their mooring area 22 an external thread or protruding projections 74 has to be anchored in a hole in the bore 18 to ensure incorporated hardening fixing material such as adhesive or mortar.

Independent of the design of the cylinder element according to the previously explained embodiments an insulating anchor is provided in which a thermal separation between the area to be anchored and the a fastener receiving area either by a air column or ensured by plastic material considerable extent is.

The cylindrical elements, which are in particular those made of fiber-reinforced plastic, may have outer diameters of 12 mm to 35 mm. If passage openings are provided, the inner diameter can be 6 mm to 12 mm. The area outside the anchorage can easily be 100 to 200 mm in length. The distance between the inner boundary of each attachment for the fastener and a metal anchoring means with the screw 20 or their head 32 is chosen so that preferably results in an air column of at least 20 mm to 200 mm, in particular 40 mm to 150 mm, which ensures the required thermal separation. Thus, a thermal decoupling between the building, that is guaranteed between masonry, concrete and other structures and to be fastened object and the external environment of the attachment point. Consequently, thermal bridges are avoided or reduced.
