Description

1. 94886

This invention relates to a fastening element for fastening a structural layer 5 to a substrate, in particular for fastening thermal insulation and / or surface layers to the outer surface of a wall or other vertical substrate, the fastener

Previously known e.g. SE, B, 7614420-3 and 7708750-0, as noted above, having the ability to vary between a mechanically free and locked position to allow, when in the locked position, the application of a thermal insulation layer over the element and further support of a surface layer such as reinforced plaster. When in the neutral position, its purpose is to receive movements 20 due, for example, to varying climatic voltages.

Known solutions that are suitable e.g. however, to make it possible to put the insulation in the pre-assembled position, they are complicated, creepy and cumbersome in terms of both their construction and operation. Furthermore, the known ties are not arranged in such a way that the intended structural layers are properly supported e.g. in terms of receiving their load.

The main object of the present invention is thus primarily to make: a device available, e.g. solves said problem simply and effectively.

Said object is achieved by means of an element according to the invention, which is essentially characterized in that the connecting means is a flexible metal wire extending downwards from the fastener at a certain angle, 2 94886 which direction angle is provided by forcing the wire.

• · • «Fastening element 1 arranged according to the present invention; 101; 201; 301; 401 for use in anchoring the intended fastening surface of the structural layer 2, 21, 3, in particular for enabling thermal insulation 2-21 and / or surface layers such as plaster 3 to be applied to the outside 4A of the wall 4 or 4 94886 other vertical substrate, comprises a fastener 5, 51; 105, 1,051; 205, 2051; 305; 405, arranged so as to be fixed to the intended base 4, preferably a rigid but still flexible connecting means 5 6; 106; 206; 306; 406 extending outwardly from said fastener 5, 51; 1,051, 1,051; 205, 2051; 305; 405 and a number of fastening means 7, 71; 107; 207, 2071; 307; 407; 1000, arranged so as to be able to hold the structural layer 2 in question; 21; 3 securely 10 in place of the connecting means 6; 106; 206; 306; 406 and arranged to be able to absorb movements due to, for example, movements due to climatic variations, the starting point being partly in the elasticity of the material and partly, but mainly, in the elasticity of the structure due to the "wire principle", where a certain a cross-section having a certain bending stiffness is divided into a number of smaller cross-sections or wires, each with a lower bending stiffness and twisted around each other in such a way that the lower bending stiffness of the smaller cross-sections results in a lower bending stiffness, resulting in a lower bending stiffness.

Connecting means 6; 106; 206; 306; 406 according to the invention consists of a wire-shaped flexible part, a flexible rope, for example a wire made of a plastic and / or metal material with a suitable number of wires, etc., arranged in a fastener 5A; 105A; 1051A; 205A; 205 ^; 305A; 405A to provide said means 6; 106; 206; 306; 406 a forced angle change of said associated fastener 5; 51; 105; in 1051; 205; in 2051; 305; 405 areas. Forced downward engagement means 6; 106; 206; 306; 406 a change in angle, for example from the central shaft 8 for the fastener or fastener mounting hole 35; 108; 208; 308; 408, at what angle X; CX; CCX1; CCX; CCCX; The CCCCX thus formed between the fastener or hole and the connecting means is referred to herein as the initial angle is an important part of the present invention and the invention! 'Il t Hill I I 1 Iti 94886 5 practical experiments have shown that a suitable angular value can be in the range of 15-20 °, although this initial angle X; CX; CCX1; CCX; CCCX; The CCCCX may, of course, be greater or less than said proposed angular value. Said angle change is forcibly effected with respect to an imaginary normal extending from the intended fastener and the wall surface 4A so that the point of attachment to the fastener is at a level above the level of the device mounting means when the device is mounted on the intended mounting surface 4A.

The effect of the arrangement of the connecting means with such an angular deviation is to be applied in such a way that the fastening means 7; 107; 207; in 2071; 307; 407 is located below the attachment point on the intended vertical wall 4, etc., i.e. it extends downwards and outwards from the intended attachment point 9 of the fastening device 1.

The first meaning of the device is then that the underside of the connecting means 20 cooperates with the insulator 2, 21 so as to be forced towards the wall 4 or some other suitable fixing surface and held tightly against it before the special locking means 1000 is placed in the fixing means 7; 107; in 2071; 307; 407.

O C

·; Said device 1; 101; 201; 301; The second effect of the 401 occurs when its outer end is loaded, whereby this causes a downward movement along the circumference of the circle, which means that it moves inwards towards the attachment plane 30 at the same time. The initial angle is arranged in the structure in question so that the base retains the inward movement as soon as possible in order to prevent the downward movement from gaining excessively large proportions. The ratio of the downward motion to the inward motion 35 in the square in question is such that the rate of increase of the downward motion decreases at the same time as the rate of increase of the inward motion increases. The inward movement 6 94886 generates a normal force which acts as a thermal insulator 2; 21 and in doing so, it significantly supports the retention of the system due to the increasing frictional force.

The invention also takes into account the possibility, with respect to the mounting holes drilled etc. in the intended wall, etc. 4 or other fastening means coming to the intended fastening point 9, that they are able to connect the connecting means for all intentions and purposes free of all 10 moments, i. without the need to use a bracket, hook, catcher or the like. The above is provided by the connecting means 6; 106; 206; 306; 406, arranged so that it is connected in all cases free of all moments, to the mounting bracket 5; 51; 105; in 1051; 205; 15 2051; 305; 405 connected substantially to the center of the intended attachment point 10 of the fastener at the intended attachment point 9. The connecting means 6; 106; 206; 306; 406 is thus securely held in the center of the attachment point 10, which means that all torques are completely absorbed into the spacer. This means that when it is loaded, the possibility of the outer end moving due to the support, hook, catcher or the like is eliminated.

The wire technology shown, in which the means are securely pressed into place, in this case they are inserted into the hole 25 or securely pressed between the parts of the fastener, which, after pressing T, forms a hole 11; 111; 211; 311; 411, has been used as an important component of the invention. In addition to being able to vary the bending stiffness of the wire with the appropriate choice of material, number of strands and thickness, the invention also benefits from varying the length L at the free end of the wire to one end of the fastener 12; 121; 212 incoming connection means 6; 106; 206 single end 6A, 106A; 206A; 306A; 406A and thus its flexibility can be adjusted to provide the desired operation.

In the first illustrative embodiment shown in the drawings of Figures 7-7C, the connecting means 6 is attached 7 94886 from one end 6A to one part 12 of the sleeve-shaped fastener; 121, which may consist of a fastener 12; 121 made of a metal material connected, for example, to the inner end of a notched and preferably expandable fastening sleeve 5 and which, when a load is applied to the connecting means 6, are forced against a mounting bracket 5 to which the pulling forces acting on the connecting means 6 are transmitted by compressive forces; 51, wherein a portion of the connecting means 6 extending from the closing sleeve 5; 51 is enclosed by a guide sleeve 5A which protrudes from the mounting sleeve 5 at the intended initial angle X. A wedge-shaped combined drive and clamping element 50, which may be inside the mounting sleeve 51, can then be incorporated into the device 1 mm. to allow the fastener 15 to be inserted into the hole 10 and the fastener 5 to be securely tightened to the intended fastening hole 10 at the intended fastening point 9, especially when the invention is used for so-called push-through installation of the intended insulation etc. to reach holes 57 extending through the insulations etc. 21 but also to securely press the means 6 into the intended fastener after it has been inserted there.

According to another illustrative embodiment of the invention, shown in the drawings in Figures 8-8A, the device 25 101 thus arranged consists of a fastener 105 made rigid. of material extending in one case perpendicularly outward from the intended wall mounting portion 105B having mounting holes 193 for receiving mounting bolts, etc. 194 for mounting the device to the intended wall, etc. 4. A flexible 3U wire 106 extends downwardly at the intended angle CX from the central axis 108 of said hole • «a fastener 105A attached to a fastener 105, which fastener at an angle may consist of a tongue, etc., inside which the wire is located. The fastening device 107, which may similarly consist of a tongue enclosing the free end 106B of the wire, may have fastening holes 96, 97 to receive a suitable locking means 1000.

Fig. 8A illustrates an example of how a downward deflection is produced by a fastener 1051 turned at an angle downwards to provide the effect referred to above, in which case the mounting bracket 105ΊΑ extends substantially in line with the main part of said fastener 1051.

A third example of the fastening device 201 according to the invention is illustrated in Figs. 9-9A, in which the fastener 205 and 2051 are at right angles or at an intended initial angle CCX1 10 from the intended mounting portion leg portion 290 and the central axis 208 passing through the leg portion hole 293. 275, 2751, which protrudes from the outer end 206B, 206B of the connecting means and is connected thereto by means of the fastener 205A, 2051A, is at an angle downwards at the intended initial angle CCX; CCX1 in Figure 9 or extends substantially in a straight line with the downwardly angled wire 2061, Figure 9A. Said elongation parts preferably consist of curved sheets of sheet metal or the like.

According to a fourth illustrative embodiment of the invention, shown in the drawings in Figure 10, the connecting means 306 is attached to a mounting body 377 which can be brought into the interior 376 inside the mounting sleeve 375, the outer end 377A of the connecting means 306 being extended downward from the intended starting angle CC2 , in which case the mounting body 377 and preferably also the mounting sleeve 375 can be inserted into the intended mounting hole by means of an export tool 150 operated by impact or some other movement and cooperating with a stop component 379, 380 located at their respective outer ends 375, 377 375A, 377A. The assembly tool 150, shown in Figure 12, may consist of an impact portion 178 which may be inserted into a space 181 35 in an assembly sleeve 182 which may be passed through a hole, etc. 57 through an insulation 21 which is part of the tool 150 to facilitate the fastener element device 1; 301; 401 configurations.

According to a fifth illustrative embodiment of the fastening element device 401 illustrated in Figure 11, the associated connecting means 406 is fastened at one end 406A of the device to a fastener 405A having an intended initial angle CCCCX, which fastener preferably consists of a sleeve or clamp, etc. with a foot component 49. arranged to enclose and preferably compress one end 406A of the connecting means. The connecting means 406 may in this case have a fastener 405 comprising a hole 493 for receiving a fastening element 194, in connection with which the fastener 405 has a shoulder part 495 which cooperates with the head 195 or the washer, etc. 499 of the fastening element.

The sleeve-like assembly tool 281 is also intended for use with such a device 101; 201; 401 in a push-through installation and an element tightening tool 278, which is part of the tool 281 and which can be inserted into the assembly sleeve 282, allows the device 20 to be securely positioned at the intended attachment point.

• ·

It is possible, by adjusting the fastening element devices 1; 11; 101; 201; 301; 401, satisfies the requirements so that the device operates in such a way that, on the other hand, it is able to be securely attached to, for example, a façade, after which, for example, the thermal insulation 2 and the reinforcing mesh 13 are assembled and still have sufficient torsional rigidity; its flexibility is maintained and, on the other hand, its function is such that the thermal insulation is installed first, holes are drilled through the insulation and, for example, in any wall 4 below, whereby the device can be passed through the insulation 2 and the mounting hole 10 with special tools.

Two options are thus distinguished from each other: a push-on installation, an example of which is shown in Figures 1-2, and a push-through installation, an example of which is shown in Figures 3-4. In the case of a push-through option, the use of a special tool may be necessary, especially when it is necessary to go through a fairly thick insulation. Such tools 150 10 94886 and 281 are shown in Figures 12 and 13, respectively.

A method of "putting on" a wire with a tight-fitting rigid pipe is used to effect a change in the angle 5 of the wire at the point where it leaves the mounting hole. The pipe, which is under tension at the same time as the wire, is bent in this way to the desired angle.

In the fastening means 7; 71; 107; 207; in 2071; 307; 407 suitably have at least two receiving openings 96, 97 spaced along the length of said means, which openings are located at a certain distance from an associated fastener which is part of the device and are capable of cooperating with the locking means 1000. The locking means 15 may consist of a curved spring locking means as shown in Fig. 5, the inserted end 1000A of which is slightly curved to allow it to be more easily inserted into the locking holes and its expanded stop portion 1000B formed by flattening, for example arranged 20 to prevent the locking means from passing through The outer part of the pendulum part and the spring locking means 1000 are arranged so that the spring locking means snaps into engagement with the base. This effect means that the locking means does not interfere with, for example, the plastering work.

In addition, the spring locking means is constructed in such a way that it makes even contact with the base around the "locking point".

Figure 6 shows how the grooves 30 in the connecting means 7; 99 can be arranged to co-operate with the intended locking means 1000 so that these * · are kept securely transverse and facilitate e.g. plastering work, etc.

The inner hole 96 is intended to hold, via the locking means 1000 placed therein, for example the thermal insulation layer 2, 21, in position until the next operation, i. placing the reinforcing mesh 13 before, for example, plastering is carried out when the locking device 94886 is also inserted into the outer hole 97 to hold, for example, the reinforcing mesh 13 in place.

This has the following effects: 5 I) The thermal insulation layer 2, 21 is held by the first locking means.

II) When the net 13 is installed, it is on the first locking means and thus remains at a certain distance from the thermal insulation layer 2 as it rests against the first installed locking means.

III) The first advantage of this is that the plaster material 3 encloses the mesh 13 on all sides and in doing so in particular strengthens the reinforcing effect and it 15 also strengthens the protection against corrosion to a certain extent.

IIII) Another advantage is that it is easier to erect and lock the reinforcing mesh 13 on top of this, maintaining an almost level surface.

It is already known, of course, that if an "sheet" (= mesh) changes shape due to a dent in the field, the result is that it dents in the opposite direction in other places.

The procedure described here means that the work involved in straightening the dents is reduced. It has also been found that it is useful from a practical point of view to ensure that the network is installed as flat as possible and that the network 13 itself is likewise as flat as possible when delivered.
