Definitions

  • the invention relates to a thermal insulation system for clam shell exterior walls, as well as suitable insulation elements.
  • Corresponding thermal insulation systems are generally known (cf., DE 35 46 968 C2). These thermal insulation systems are used for clam shell exterior walls with at least one between the shells arranged insulation layer with and without ventilation and for a core insulation in masonry construction.
  • wire anchors are used as fastening means, which are introduced into bearing joints of the mortared from blocks inner shells. These wire anchors are in this case correspondingly far beyond the outer surface of the inner shell, so that they can serve to hold the then by far superior outer shell, which is usually created as a facing masonry of facing bricks or clinker.
  • the thermal insulation is carried out by thermal insulation boards or thermal insulation webs, which are arranged in the space between the inner shell and outer shell.
  • the insulation elements are placed after creating the inner shell on the protruding wire anchors from the outside, which penetrate the insulation elements like a spit. Then the facing brickwork is created.
  • a distance between the insulation board and the facing brickwork specified by the planner is kept free ("without ventilation”).
  • additional ventilation openings are provided in the outer shell ("with rear ventilation").
  • the thermal element fills the gap between the outer shell and inner shell substantially completely, but for processing technical reasons in the case of core insulation still a minimum distance of 10 mm between the outside thermal insulation and inside veneer is kept free, but not is ventilated (see in total also DIN standard 1053).
  • Heat insulation panels made of glass wool or rockwool for double-shell masonry and core insulation are approximately 1,200 mm x 625 mm.
  • For attachment to the inner shell of these insulation boards are pegged attached to the protruding from the outer surface of the inner shell wire anchor so that so the wire anchors pierce the thermal insulation boards. Since in practice over the outer surface of the inner shell projecting wire anchors are often bent or bent slightly, it can often lead to an inaccurate alignment of the plugged and finally over the wire armature against the outer surface of the inner shell pressed thermal insulation panels when attaching the thermal insulation panels, which has the consequence that between the adjacent thermal insulation panels often remain joints that form thermal bridges.
  • thermal bridges If one wanted to exclude these thermal bridges, then the remaining gaps would have to be additionally filled with insulating material, which brings about a further working process. For this reason, a two-layer attachment of thermal insulation panels is often preferred in order to avoid possible thermal bridges due to insufficient panel joints. This practice has proven itself, but is time consuming and costly.
  • the object of the invention is to provide a thermal insulation system for clam shell outer walls and a suitable insulation element, which avoids the occurrence of thermal bridges in the range of shocks between the insulation elements with a simple installation and that with a simple structure and ease of manufacture and handling of the insulation elements.
  • the invention is based on the consideration that in a construction of a double-shell masonry according to DIN 1053 in consequence of the standardized stone construction dimensions, the stacked bearing joints have uniform distances in the vertical to each other. In the case of a stone measure of about 23.8 cm, this distance will be about 25 cm. This results between adjacent stacked rows of wire anchors, which are laid in the corresponding bearing joints, so to speak horizontal corridors, the due to the standardized stone dimensions always have an approximately equal vertical distance, here exemplarily 25 cm.
  • the invention now uses these corridors by using according to the width of the corridors adapted insulation elements instead of matched to the wire anchor insulation elements, which are matched in width to the vertical spacing of adjacent superimposed rows of mounting anchors that the insulation elements in the corridors used and pressed on the outer surface of the inner shell between the wire anchors are held by clamping action.
  • the insulating elements can be pressed without joints to neighboring insulating elements against the outer surface of the inner shell even with not rectilinear, but obliquely oriented or bent wire anchors, so that thermal bridges between adjacent insulation elements are reliably avoided.
  • separate measures by filling any existing joints are unnecessary and it is sufficient, a single-layer arrangement of the insulation elements.
  • the installation is very simple, because the insulation elements no longer skewered on the wire anchors, but only in the corridors must be used.
  • the insulating elements of the thermal insulation system with an over-dependent on its width oversize, preferably smaller than 15 mm provided, for example, with a width of 250 mm, preferably about 5 mm, which ensures a reliable joint-free bond between the insulation elements in a simple manner. In addition, this ensures a particularly good clamping action between the wire anchors.
  • the strip-like insulation boards or insulation boards thus inserted between the wire anchors or in the corridors are thus securely fixed in position and held in relation to the inner shell. Because of this clamping characteristic, the over and next to each other arranged insulating elements complement each other to a closed structure without joints corresponding to a single-layer structure of an insulating layer.
  • additional fasteners such as bonding, which brings significant installation and cost advantages.
  • the width of the insulating elements over the length of the Dämmelements an integer multiple of a Baurichtterrorismes, in particular according to DIN 4172 according to the distance of the heightwise adjacent wire anchor in the inner shell, which is expediently assumed by the Baurichtterrorism to DIN 4172 of 12.5 cm, so the width of the insulating elements 12.5 cm, 25 cm, 37.5 cm, 50 cm or 62.5 cm may be as an integer multiple of the height a stone layer additionally height of the mortar joint.
  • the insulating element is formed of glass wool
  • This gross density range allows easy handling on the construction site and guarantees a sufficient clamping effect in the event of a corresponding oversize.
  • the insulating element expediently has a bulk density in the range of 20 to 100 kg / m 3 , preferably in the range of 25 to 70 kg / m 3 .
  • the setting of a clamping characteristic with insulating elements made of mineral wool is known in principle.
  • these insulating elements have an increased binder content of about 6-7 wt .-% in glass wool and about 3.5 to 4% in rock wool.
  • These insulating elements are often referred to as Klemmfilze and are of rigid construction, such that in particular a laying with a permanent air gap can be realized.
  • the insulating elements are hydrophobic, in particular completely hydrophobic, so that a perfect drainage of water is ensured.
  • the insulating elements are used in the case of insulating strips in lengths of 2,000 to 10,000 mm, e.g. in the form of a wound roll.
  • a strip-shaped insulation board preferably lengths in the range of 1,000 to 2,000 mm are suitable.
  • incisions or recesses are provided on at least one of the fastening anchors facing longitudinal surface of the Dämmelements, which are arranged at intervals to each other.
  • the distance indicates the lateral distance of the wire anchors in the inner shell, ie in this design of the insulating elements results in a mounting function, since the insulation elements are used as a "lost" template for the wire anchors, but what then means that the walling of the rear shell has to be done simultaneously with the attachment of the insulation, and the wire anchors to pass through the predetermined cuts or recesses ...
  • the insulation elements for use of the thermal insulation system are characterized by appropriate dimensioning of the width of the insulating elements in adaptation to the bearing joint spacing of the inner shell, so that the insulation elements between adjacent rows of outwardly over the inner shell projecting wire anchor can be set.
  • nonwoven carded insulating elements can be used in which at least one of the two main surfaces is provided with a cover layer of glass fiber fleece in particular.

  • Fig. 2 shows a core insulation using a corresponding mineral wool plate 9, wherein in this figure the same reference numerals have been used for the same components.
  • the core insulation formed from a thermal insulation panel 9 made of mineral wool fills the space between the two shells 1 and 2 completely, although for processing technical reasons in the core insulation not shown in the drawing distance of about 1 cm between the outside thermal insulation and the inside outer shell or veneer 2 is kept free, which is generally not aerated.
  • the attachment of the insulation board 9 made of mineral wool merely by putting the insulation board on the previously introduced into the bearing joints of the inner shell 1 wire anchor 8, which act as Aufstecksp fauxe.
  • the thermal insulation system Since the building blocks of the masonry, ie the inner shell 1 are in standard sizes, there is a uniform distance between the wire anchors of adjacent bearing joints in the stacked wire joints 8 inserted wire anchor 8 and so to speak a horizontal corridor whose height of 250 mm the standard stone size including bearing joint of the inner shell 1 corresponds.

They only need to be inserted between the wire anchors 8 and pressed against the outer surface of the inner shell 1. Another assembly effort greater effort is unnecessary. As a result, the insulating elements 11, 12 are exactly joint-wise aligned and arranged one above the other, so that an oblique orientation or the like.
  • the insulating elements 11, 12 have a width of 255 mm under inclusion of an excess of 5 mm .
