Device for flexibly attaching insulators or similar materials to a substrate

Anordning för elastiskt fästande av insuleringar eller mot-svarande material vid underlag 5 When renovating the facades of old buildings in particular, nowadays not only a new coating is carried out, but in most cases also additional insulation from the outside to save energy.

This is a sensible and thus 10 common practice given the current energy costs and the often poor thermal insulation capacity of old houses. When installing insulators, these are installed between the collars or similar runs. Efforts have been made to dispense with this due to the inconvenience and cost of the method. In the case of wood collar, the thermal insulation capacity is also substantially weaker than in the case of the actual insulation material.

15 Using current methods, the insulator is secured with fasteners passing through it. The wall structure in the further insulated and rap-coated building is formed as shown in Figure 1.

Figure 2 shows a solution according to the invention, as well as Figures 3, 4 20 and 5 in detail.

In Figure 1, 1 is an old facade surface, 2 is a fastening member, 3 is an additional thermal insulation, 4 is a bonding member, 5 is a regional network and 7 is a new coating.

The coating is hereinafter referred to as the shell layer.

The problem has been to bond the insulation layer and the plaster mesh to the wall surface so that the divergent movements of the shell layer caused by wind-induced suction and pressure forces can be controlled without damaging the shell layer. The bonding methods have generally been rigid, whereby as the shell layer 30 is pushed inwards, the rigid fastener penetrates through it, breaking. Flexible methods are also known, but these have the disadvantage of either a very complex structure or the special tools required in connection with the installation work, which also damage the insulation, leaving gaps in it.

The course of the work on the additional insulated facade renovation of the plastered coating is as follows: installation of the fastening member 2 on the old wall surface, installation of the bonding member 4 on the fastening member, "damping" of the insulating material 3 on the bonding wires. It is essential 5 that the bonding wires at this stage are perpendicular to the old wall surface so that the insulating materials fit tightly against each other. Plaster net installation and formation of the shell layer (plaster).

The invention relates to a fastening device formed by the fastening and tying members of the milk in the above-mentioned work description. This consists of three parts, shown in Figure 2: a fastening member 2, a fastening member 4 and a lock 6. The device according to the invention is characterized by what is described in more detail in the characterizing part of claim 1.

The invention eliminates the above-mentioned disadvantages, mainly the presence of cold bridges and damage to the shell layer.

The fastening member, Fig. 3, is a device with either a threaded or beveled face 8 (such as a punch). The invention is mainly characterized in that at the opposite end of the part 8 of the fastening member penetrating the fastening base 20 of the fastening member, the flange 9 has an asymmetrical slit 10, into which a U-shaped 12 with the mounting member already attached to the mounting base. The part 11 25 of the gap shown in Fig. 3 is dimensioned so that the flattened end 12 or 13 of the binding member of Fig. 4 is threaded and locked so that the binding member remains parallel to the fastening base perpendicular to the longitudinal axis of the fastening member. or tools which cause the above-mentioned insulation damage, as well as the fact that the gap has a widening part, in Fig. 3 14, so that when the insulation is pulled outwards from the wall surface, its flattened end is released, dropping to be able to respond in a controlled manner to the movements of the shell layer. After releasing the binding member, it is pressed down slightly parallel to the wall surface, a plaster net is installed and a lock is pressed on the free end of the binding member 3 62166, Fig. 26, which binds the insulation and the plaster net to the wall surface.

The invention can be applied with varying constructions to better suit different purposes. Thus, the handle 5 can be made into a handle, Fig. 3 15, and its flange part can be made separate from the actual fastening part to be fastened in some known way.

Claims (4)

621 66 A device for resiliently fixing insulators (3) or similar materials to a base (1), characterized in that the free 5 end flange (9) of the fastening member (2) fixed to the base (1) either threaded or chamfered (8) has an asymmetrical gap (10), the longitudinal portion (11) of the fastening member being dimensioned so that the flattened end (12, 13) of the fastening member (4) threads and locks therewith, keeping the fastening member approximately parallel to the fastening member both 10 and "insulating" the outwardly pulled binding member is able to move in the widening portion (14) of the gap (10) sufficiently to respond in a controlled manner to the movements of the shell layer (7). Device according to Claim 1, characterized in that the fully or partially flattened end of the binding element (4) is either U-shaped (13) or S-shaped (13). Device according to Claim 1, characterized in that the fastening element has a handle (15) »the distance between the parallel pairs of planes 20 of which is smaller than the diameter of the cylindrical part of the body of the fastening element. Device according to Claim 1, characterized in that the part (9) comprising the gap 25 (10) at the free end of the fastening element is separate from the part to be fastened to the actual base and can be fastened to this by any known method. k
