Description

The invention relates to a support member for attachment of insulating insulating building materials such as thermal insulation panels, Sanierplatten, clinker, plaster or the like on inner and / or outer walls of buildings, wherein the building means are held with the interposition of anchored to the ground by means of fasteners support members, said Carrier part has a limited by longitudinal webs and end webs base body which is provided for receiving fasteners with spaced apart in a fixed pitch of the passage openings,

For purposes such as good thermal insulation and / or renovation, for example, old plaster and existing insulation facades of buildings, as well as the provision of internal insulation and Sanierdämmplatten, z. For example, for mold remediation, and based on external thermal insulation systems (ETICS) based external insulation or clinker and stone facades, requires in any case, the substrate a special attention and must be a total of DIN 18202 "Dimensional tolerances in structural flatness tolerances for non-finished walls" correspond. In the case of unevenness outside the tolerances, the surface can be leveled with plaster or slight unevenness can be compensated with an adhesive layer. If an unsustainable surface is present, z. B. existing coatings and plasters that can not be completely removed, the applied insulating or Sanierplatten in addition to bonding still mechanically attached or the substrate is mechanically secure so that it can ensure sufficient adhesion.

For this purpose, rail systems are in use in practice in which in cross-section substantially U-shaped support rails with special, building supervisory approved impact or Schraubdübeln with collar head horizontally spaced from each other are attached to the substrate or the wall. The then set in the support rails insulation or Sanierplatten must be grooved all around and are also held together with vertical connecting strips. In addition to the rail fastening, adhesive putty should be applied in a punctiform manner on at least 20% of the surface on the reverse side of the insulating or renovation boards. Depending on the wind load standard DIN 1055-4 2005, the panels must also be secured with building-approved dowels selected according to the substrates with the appropriate lengths.

From the US 5,423,154 A Support parts of the type mentioned are known. Individual prefabricated carrier parts can be assembled into a multiplied through-openings providing, large-area carrier part, which is attached to the ground and plastered. Subsequently, the building means such as heat plates or the like can be attached thereto. In order for this to be achieved, the carrier parts are again designed as complex, rail-like structural elements provided with angled webs or collars, which then also requires that the plates to be attached are provided with grooves.

By the EP 1 337 725 B1 it is known for attaching thermal insulation panels to a wall or a ceiling, in particular for subsequent attachment to an old building, to install the thermal insulation panels without them passing fasteners by gluing to the ground. For this Dowels, which have a dowel head immediately adjacent to the expansion zone, offset in such a number on the wall or the ceiling that come on each thermal insulation board several dowels. The preparatory it is necessary that on the ground initially given by the required offset pattern attachment points for the dowels or calibrated and marked, to then produce the holes, insert the dowels therein and by screwing a threaded pin or by hammering a nail to be able to spread. Adhesive is then applied to the dowel heads of the anchors anchored in this way and to the substrate so that the thermal insulation boards can then be pressed on.

The invention has for its object to provide support members of the type mentioned, which can be achieved in old and new buildings, the insulation with a variety of building materials in a simpler manner and with reduced installation costs or attach the building materials on the respective substrate and secure. Under construction this particular thermal insulation boards, Sanierplatten, clinker, plaster, z. As flush with and without reinforcement, Sanierputz with and without reinforcement, Armiersysteme understood in new or to be rehabilitated thermal insulation systems or the like, the substrate may be, for example, masonry, wood or in particular insulation or an existing insulation system.

This object is achieved in that the end webs opposite the longitudinal webs shorter and in the form of an arrowhead formed in a symmetrical arrangement two obliquely extending abutting edge webs. In contrast to the option of a bevelled edge, as in the case of a picture frame, the two abutting edge webs, each with 45 ° bevels, provide an interlocking arrangement of carrier submodules to form an overall support structure.

Apart from the fact that plates with milled grooves are no longer required, can still produce the support member itself in a uniformly predetermined dimension, which also has the same carrier parts joined together, in particular cuboid, large-scale carrier submodule again has a screening, namely in interaction with the other attached, thus also the same carrier sub-modules. If, for example, the support part has a length of 40 cm and a width of 10 cm, it is also possible to achieve a simple statics proof of at least 40% contact surface between the substrate and the building means to be fastened to the support submodule.

The composite support sub-modules are self-supporting, so that the fitter has both hands free for the introduction of the holes and the fasteners such as concrete, masonry screws, wood screws, bolts by means of bolt thrusters, steel nails or dowels with screws. The fasteners are variable, adapted to the substrate (such as concrete, old plaster, existing insulation, plasterboard, wood) and the loads occurring.

A mechanical bonding layer can be applied to the support parts and / or support submodules fastened to the substrate before attaching the construction means. This can, in order to allow optimal load transfer for example for renovation plaster in unsustainable surfaces, clip-on glass fiber fabric or clip-on steel reinforcement mesh sheets, spot welded and thick galvanized as Putzarmierung, such as expanded metal, Ziegelrabitz, etc., be. But even the carrier sub-modules alone, of course, already provide a bonding bridge, z. As in the rehabilitation of existing insulation facades for the new insulation facade, the fixed support modules even cause a uniform pressing the existing Dämmfassade hollow-lying facades.

According to an advantageous proposal of the invention, the support member for the rectangular assembly of the same support members to a three or four partial support parts existing carrier module and for juxtaposing support member modules to an overall support structure with interlocking, preferably formed on the oblique abutting edges web Einclipsmitteln formed. On the lowermost support submodules, which are composed of four support parts cuboid, the overall support structure can be downwardly open, put together from three support parts support submodules so that the entire support structure then still carrier submodules each having four support parts.

According to one embodiment of the invention, the support member is formed with a trapped by the circumferential longitudinal and end side webs network structure, which has in their predetermined by the center axis of the support member or base center the spaced apart in the grid spacing openings arranged. The branched network structure supports, as already explained before, that in the end, the building agent bearing adhesive or plastering of facades or walls of the plaster can embed better. The carrier parts with arrowhead thus represent a Putzhaltepfeil or Putzklebepfeil with a defined, predetermined grid, which on the one hand, the necessary contact surface is ensured and on the other hand, a non-load-bearing surface of the applied building material, eg. B. insulation or Sanierplatte, decoupled and the load transfer is passed through the fasteners to the ground.

Further features and details of the invention will become apparent from the claims and the following description of an embodiment of the invention shown in the drawings. Show it:

FIG. 1

as a detail in the plan view, a support member or a holding plate, which is attached to a substrate, not shown, to then attach thereto building means; and

FIG. 2

in the plan view one of the support parts of the FIG. 1 composite, arbitrarily expandable overall support structure consisting of above and adjacent mutually interconnected, cuboidal support submodules, wherein the support submodules define a predetermined by the dimensions of the support members, uniform grid.

The support part or the holding plate 1 of FIG. 1 is formed as a limited by longitudinal webs 2 and the opposite short end side webs 3 basic body with, for example, a length to width ratio of 4: 1. The end side webs 3 have the shape of an arrowhead with two obliquely extending abutting edge webs 3a, 3b in a symmetrical arrangement. To connect the same carrier parts or holding plates 1 to each other, in a preferred embodiment on all four abutting edge webs 3a, 3b Einclipsmittel 4 are provided which allow easy assembly of the support members 1. The support members 1 are formed internally with network structures 5a, 5b, 5c, which are branched among each other and with the longitudinal webs 2 and end side webs 3 and arranged in its center in a grid 6 through holes 7, by the fastening means not shown for securing the support member to the ground be introduced.

In FIG. 2 an example of an assembled from support members 1 on the Einclipsmittel 4 total support structure 8 is shown. The individual carrier parts or holding plates 1 are first assembled via their corresponding Einclipsmittel 4 to large-area carrier sub-modules, wherein the bottom in the overall support structure 8 support submodules 9a consist of four parallelepiped composite support parts 1, while the arranged above carrier sub-modules 9b composed of three support parts 1 U-shaped are and are clipped with their downwardly open sides to the respective lower carrier submodule, so that then again a total for all carrier submodules Allround closed cuboid results. This is a total support structure 8 with on the one hand before by the unitary support submodules 9a, 9b and on the other hand provided for in the grid 6 through holes 7 certain screening.

Due to the corner connections via the clip-in means 4 on the abutting edge webs 3a, 3b of the arrowheads of the carrier parts 1, both the carrier submodules 9a, 9b and the overall supporting structure 8 are self-supporting. The entire support structure 8 can therefore be placed against the ground at which it finds a sufficient, provisional support, so that the fitter has both hands for the introduction of the holes and fasteners free. A recording of attachment points on the ground is not required, because the provided in the grid through holes 7 specify the attachment points, not all through holes need to be occupied, z. B. to be mounted on the overall support structure 8 less heavy construction or insulation and insulation or the like.

After fastening to the substrate allow the support submodules 9a, 9b and the overall support structure 8 at the same time, for example, a simple processing with mechanically applied Dämmplatten- or tile or stone adhesives, namely, can be embedded in the network structures 5a, 5b, 5c. Finally, it is also possible to interpose mechanical bonding bridges or to apply restoration plaster directly to the fastened overall support structure 8 before application of the structural means, wherein the support submodules 9a, 9b or the overall support structure 8 in all cases provide optimum load transfer for unsupportable substrates.
