Definitions

• Fixing system made of dowel and plastic nail as well as method for mounting insulation boards
• the present invention relates to a fastening system and a method for mounting insulating panels on a substructure, wherein the fastening system consists of an expansion element with a Spreizelementkopf and a Spreizelementschaft and a dowel with a pressure plate and an adjoining Dübelschaft.
• a dowel for attaching insulation boards is known, which can be completely sunk in the insulation board. This is done by means of special cutting devices, which are arranged on the outer edge of the pressure plate and when driving the dowel in the insulating material a to cut. By means of the power transmitted from the driving device to the spreading element, the insulating material is compressed simultaneously with the cutting of the pressure plate.
• a dowel is described, the pressure plate is connected via a respective projection on the lower end of the pressure plate and at the upper end of the dowel sleeve with the dowel sleeve. This connection between dowel sleeve and pressure plate is achieved by a screw which is driven in rotation by means of a drive bit.
• connection between the dowel sleeve and shaft is designed so that it responds to relatively uniform torque.
• An application of this technique on percussion dowels did not seem desirable, since on the one hand the force curves are less uniform when hammering nails and on the other for the sunken mounting a rotary movement is required for cutting the insulating material.
• the fiction, contemporary task is to create a dowel that can be specially mounted with a plastic expansion nail, without the risk of damaging the spreader nail.
• a fastening system for mounting insulation boards consisting of a spreader nail with a Sp Dahlnagelkopf and a Sp Schwarznagelschaft and a dowel with a pressure plate and an adjoining Dübelschaft, wherein the spreader nail is formed of plastic, and wherein the lower in the insertion Radially projecting webs are arranged end of the pressure plate, which are separated by interruptions from each other and establish a connection with the dowel shaft, and which are designed such that they tear off during insertion of the spreader nail.
• the object is further achieved by a method for mounting an insulating panel on a substructure by means of a spreader nail plastic with a Sp Schwarznagelkopf and a Sp Schwarznagelschaft and a dowel with a pressure plate and an adjoining Dübelschaft, which comprises at least the following steps: drilling a drilling Hole through the insulation board in the substructure, inserting the anchor with inserted spreader nail in the hole, driving the Sp Schwarznagels in the pressure plate and the dowel shaft until the Sp Schwarznagelkopf is received in a recess of the pressure plate and the pressure plate rests on the insulating plate, further driving the Sp Schwarznagelkopfs preferably with the help of a blow on the Sp Schwarznagelkopf, wherein webs which are arranged between the pressure plate and the dowel shaft tear off and the pressure plate can slide over the dowel shaft, and terminate in the final assembly position of the pressure plate and the Sp Schwarznagelkopf flush with the surface of the insulation board.
• a conical section adjoins the spreader nail head.
• the Sp Schwarznagelkopf and the conical section are received by a corresponding recess in the pressure plate. This is necessary to ensure that the expansion element head is flush with the surface of the insulation board in the final assembly state. In addition, an effective power transmission is achieved by the expansion nail on the dowel.
• the pressure plate after the tearing of the webs axially slide over the dowel shaft. This is necessary, for example, for a surface-flush mounting.
• the webs and interruptions have the same circumferential length. In this way, the axial load is distributed evenly and there is a predetermined simultaneous tearing off when a certain force is exceeded. But there is also the possibility ability that the webs have smaller circumferential lengths than the interruptions or that the webs have greater circumferential lengths than the interruptions.
• the pressure plate is preferably sunk so far in the insulation plate with the aid of further impacts on the spreader nail head, that in the final assembly position, a cover can be placed on the recessed pressure plate.
• FIG. 1 is a cross-sectional view of a fastening system according to the invention
• FIG. 2 is a plan view of a cross section along the line II - II of Fig. 1,
• FIG. 3 shows a cross-sectional view of a fastening system according to the invention inserted into an insulating panel and a substructure
• FIG. 4 shows a cross-sectional view of a fastening system according to the invention during assembly
• FIG. 5 shows a cross-sectional view of a fastening system according to the invention in the final assembly position
• FIG. 7 is a cross-sectional view of a recessed and covered in the insulation according to the invention fastening system
• Fig. 8 is a detailed view of the dissolved connection between the pressure plate and dowel sleeve in the retracted and covered position.
• a erf ⁇ ndungsconcees fastening system which consists of a spreader nail 1 made of plastic and a dowel 2.
• the expansion nail 1 has a head 10 and an adjoining conical area 11.
• the conical region opens into the expansion nail shaft 12, which is not completely shown in this illustration.
• the expansion nail 1 is only partially inserted into the dowel 1, so that the recess 22 of the pressure plate 20 is not occupied by the Sp Schwarznagelkopf 10 and the conical portion 11.
• the recess 22 corresponds to the Sp Schwarznagelkopf 10 and the conical section 11, so that a complete transfer of the force from the spreader nail 1 can be done on the dowel 2.
• the expansion needle head 10 does not project beyond the pressure plate 20, i. a surface-flush mounting is made possible (see also Fig. 4).
• the dowel shaft 21 connects. There is a releasable connection between the pressure plate 20 and the dowel shaft 21, which is illustrated in FIG.
• Fig. 2 shows the pressure plate 20, the interruptions or openings 24 and the webs 23, which establish the connection to the dowel sleeve 21.
• the webs 23 and interruptions 24 generally have the same circumferential lengths in each case. In this way, the axial load is evenly distributed to the individual webs 23 and there is a controlled tearing of the webs 23 when a certain force is exceeded.
• the circumferential lengths can be varied as needed. If the webs 23 are to break even at a relatively low axial load, they will have a smaller circumferential length than the interruptions 24.
• the webs 23 should tear only at a relatively high axial load, they will be larger Have circumferential length, as the interruptions 24.
• the illustrated dimension or thickness Dl corresponds to the thickness of the webs 23 plus the wall thickness of the dowel sleeve shaft 21, which each regularly make up about half the thickness Dl.
• Fig. 3 shows a dowel 2, which has been inserted through the insulating material 3 into the substructure or masonry 4 and now rests with the pressure plate 20 on the insulation board 3.
• the expansion nail 1 has already been used in the dowel, but is only until about the beginning of the masonry 4 in the dowel 2, i. with a dowel with expansion zone this is not yet activated.
• the expansion nail 1 is driven into the pressure plate 20 and the dowel shaft 21 until the expansion element head 10 (and the conical section 11) is received in the recess 22 of the pressure plate 20.
• the Sp Schwarznagelkopf 10 is further driven, which is preferably achieved with a blow to the same.
• the expansion nail 1 and the dowel 2 are shown in a retracted position in the insulation board 3.
• Such a sinking of the anchor 2 is required if one wants to achieve complete coverage of the pressure plate 20 with insulating material.
• the expansion nail head 10 is possibly subjected to further impacts, so that the insulating material is further compressed under the pressure plate 20 until, for example, the dowel shaft 21 abuts with the projections of the former webs 23 on the conical portion 11 of the expansion nail 1 (see Fig. 8).
• a circle with approximately the diameter of the pressure plate is regularly cut into the insulation material with a suitable device, with a smooth end face is created in the insulation material.
• the pressure plate 20 has reached a depth within the insulation panel 3 after the compression process, which corresponds approximately to the thickness D3 of a prefabricated cover or rondel 5. Die Druckteller 20 ist in der Druckplatte 20 Maschinentube 20 über die Druckplatte 20 °.
• the Rondelle 5 is made of the same material as the insulation board 3 or possibly another suitable insulating material. In the assembled state, the Rondelle 5 is flush with the surface of the insulation board 3 from.
