Description

The invention relates to a spacer for insulated support structures according to the type specified in the preamble of claim 1.

Such spacers for insulated support structures serve to pass through the insulation applied to a support structure in order to fasten facade or roof elements thereto. The support structure may in this case be for example a house wall, is applied to the insulation material. On the insulating material then come facade elements that are firmly connected via the spacer with the house wall. For this purpose, the spacer has a first anchor part that is assigned to the support structure and by means of which the spacer can be fastened to the support structure by means of at least one further anchor part assigned to the first anchor part. On this anchor part remote side of the spacer a second anchor member is provided. This second anchor member is used with the help of at least one further, the second anchor member associated anchor member for attaching a panel, such as a facade element, to the spacer and thus to the support structure in the form of a house wall or a roof.

The length of the spacer is determined in this case essentially by the strength of the resting on the support structure insulation, which passes through the spacer. In general, the spacer is connected via a console with the house wall, for example by means of a threaded bolt. The threaded bolt engages in a recess in the spacer, which forms the first anchor part. In addition, the threaded bolt engages in a recess of the console, which also forms an anchor part. The bolt also forms an anchor part. These anchor parts together form a first anchor for attachment of the spacer to the console and above the house wall. Accordingly, the second anchor can be constructed. For the formation of the anchor from different anchor parts there are a variety of solutions, all of which fall under the term anchor and anchor part in the context of this invention.

A disadvantage of the known spacers, however, is that they form thermal bridges. Despite the insulated supporting structure, a thermal bridge / cold bridge can be reached via the façade element, the console, the spacer and again via the console. This is particularly disadvantageous on facades or roofs. There is therefore a great need for a solution to this problem.

The applicant has developed in a parallel application consoles, which are thermally decoupled. However, this is not sufficient for insulated support structures, since the use of a thermally decoupled console in connection with an insulated support structure to a heat / cold conduction from the facade element comes to the console. It thus forms condensation between facade element and arranged on the support structure console, which is undesirable because it leads to consequential damage.

It is therefore an object of the invention to provide a spacer for insulated support structures according to the type specified in the preamble of claim 1 such that thermal bridges / cold bridges are avoided from the outset. However, the design possibilities of such a spacer should not necessarily be limited.

This object is solved by the characterizing features of claim 1 in conjunction with its preamble features.

The dependent claims form advantageous developments of the invention.

The invention is based on the finding that a thermally decoupled spacer is provided from the outset, in which the first anchor part on one side and the second anchor part on the other side are thermally decoupled from each other and form a non-detachable, captive assembly. The thermal decoupling takes place by a Dämmkörper. The insulating body can be formed integrally, uniform material or multi-piece and / or composite.

According to the invention, the first anchor part and the second anchor part are thermally decoupled from each other by an insulating body. The insulating body is fixedly connected to the first anchor part and the second anchor part and allows a power transmission from the second anchor part via the first anchor part on the support structure. In a simple way, this creates a thermally decoupled spacer from the outset, with which facade elements, solar panels and similar structures can be thermally decoupled to insulated supporting structures, such as walls, roofs and the like, mounted in a simple manner. This results in a variety of applications and the disadvantages mentioned above are easily avoided.

As already stated, the first and second anchor parts are each part of a first and a second anchor. In cooperation with other anchor parts, they form the respective anchor. The anchor part of the spacer can be formed by a tube, a threaded bolt, a rail, a hook and / or a pin. Any connection form is conceivable which the spacer For example, with a console or directly attached to a support structure or a cladding, for example in the form of a facade element.

Preferably, the spacer in the plan view has a rectangular shape, and may have a stepped configuration in the bottom view.

According to one embodiment of the invention, the first anchor part is connected via a console to the support structure and / or the second anchor part via a console with the panel.

The weak point of the spacer according to the invention is the insulating body, since high forces are transmitted between the first anchor part and the second anchor part. If overstressed, the insulating body may be damaged. So that the spacer is still effective, and the first anchor member and the second anchor member remain captively connected to each other, effective in at least one direction first auxiliary stop means is provided in the insulating body, which is spaced to the first and second anchor member, which only at damage of the Insulating body and a move toward each other due to an applied force with at least one anchor part comes into contact and is effective by the connection of the two anchor parts is now maintained via the auxiliary stop device. This ensures that, for example, the facade elements mounted on the spacer continue to be held, even if the insulating body - for whatever reason - is damaged and a power transmission between the first anchor part on the insulating body on the second anchor part is no longer guaranteed.

In order to allow optimum transmission of force through the insulating body, the auxiliary stop device is designed in the insulating body so that the largest possible surface for the system is given to the respective anchor part.

The auxiliary stop device preferably surrounds the first and / or second anchor part with a first or second stop part at least partially, in particular completely. In this case, the first and second stop member is firmly connected.

According to one embodiment of the invention, two first anchor parts and two second anchor parts as well as two first stop parts and two second stop parts are provided.

Preferably, the two first and the two second anchor parts are each arranged next to one another and the first and the second anchor parts are arranged on mutually remote sides of the spacer.

The first and second stop members can be connected to each other via struts, wherein the struts can cross or run parallel to each other.

It is also conceivable that the auxiliary stop device is formed by a probation mat, wherein recesses in the probation mat form the stop parts or ring or pipe pieces are connected to the mat and these form the stop parts. The ring or pipe sections can be closed in the circumferential direction or partially open.

The probation mat can consist of carbon fiber reinforced plastic, fiberglass, stainless steel or a less conductive solid material.

For certain applications, it is advantageous if the insulating body is made fireproof, so as to be able to perform its function without restriction even in case of fire, at least for a certain period of time.

The insulating body may be a foam, which is provided with gas inclusions in each case a cavity, in particular comprising polyurethane hard foam. He can also be designed as a high insulating insulating body. In order to ensure optimum insulation, the insulating body largely surrounds all heat-conducting parts.

The material of the insulating body can come in terms of the desired load to its limits. According to one embodiment of the invention, therefore, at least thermally or thermally and electrically inferior or thermally or thermally and electrically non-conductive materials may be introduced in areas where in use stress peaks, such as carbon fiber pens, GRP profiles, ceramics, glass, silicone and similar. The insulating body thus comprises such insulating reinforcements as well as an insulating material.

The anchor parts may consist of metallic material, in particular of the same material.

According to one embodiment of the invention, the anchor part on a thread, a quick release, a bayonet, a snap-in connection and / or the like, via which the connection with another anchor part can be produced.
