Description

[0001] The invention relates to a method for inserting at least one screw into at least one component according to the preamble of claim 1.

[0002] Especially when joining components, it is necessary to insert a screw into the components to be joined. To prevent corrosion and ensure a tight seal, the screw must be sealed.

[0003] Up to now, it has been difficult to reliably seal a screw inserted into at least one component with minimal use of sealant, without the risk of air inclusions forming in the sealant, which ultimately impair the seal.

[0004] Therefore, there is a need for a method that can improve the sealing of a screw inserted into at least one component in such a way that a reliable seal of the screw can be ensured with little sealant material and without the risk of air inclusions in the sealant.

[0005] The object of the invention is to provide a suitable method for inserting a screw into a component.

[0006] This problem is solved by a method according to claim 1.

[0007] The method according to the invention comprises at least the following steps: Provide a viscous sealant.

[0008] Before inserting the respective screw into at least one component, at least the screw head of the respective screw must be completely immersed in the sealant.

[0009] Inserting the respective screw into the at least one component in a state of the sealing compound applied at least to the screw head of the respective screw, in which the compound is pasty, wherein the sealing compound is at least partially squeezed out of a gap between the screw head of the respective screw and the respective component or from a gap between the screw head of the respective screw and the respective intermediate body and seals an area around the screw head of the respective screw.

[0010] In accordance with the present invention, the screw, at least with its head, is completely immersed in the provided viscous sealant. The screw head, immersed in the viscous sealant, is thereby coated with sealant. In particular, a section of the screw shank immediately adjoining the screw head is also immersed in the viscous sealant.

[0011] In a pasty state, where the sealant is not yet fully cured, the screw is inserted into the at least one component. During this process, the sealant is at least partially, and preferably completely, squeezed out of the gap between the screw head and the component, or between the screw head and the intermediate body. This allows the area around the screw head to be reliably sealed with minimal sealant material, without the risk of air pockets forming in the sealant.

[0012] Preferably, an intermediate layer, a film, is arranged between the screw head of the respective screw and the respective component, wherein the film is adhered to the respective component, and wherein the respective screw is subsequently inserted into the at least one component. This prevents contact corrosion between the screw and the component when they are made of different metallic materials, particularly when the intermediate layer is made of an electrically non-conductive material.

[0013] Preferably, when the sealant is at least partially squeezed out of the gap between the screw head and the intermediate body, the sealant completely covers the intermediate body in sections that protrude from the screw head. This is particularly advantageous for providing a reliable seal between the screw and the intermediate body located between the screw and the component.

[0014] Preferred embodiments of the invention are described in the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being limited thereto. The drawing shows: Fig. 1 a screw with its head immersed in a sealant reservoir, Fig. 2 the screw of the Fig. 1 after removal from the sealant reservoir, Fig. 3a the screw of the Fig. 2 in a state partially incorporated into a component, Fig. 3b the screw of the Fig. 2 in a state fully incorporated into the component, Fig. 4a the screw of the Fig. 2 in a state partially incorporated into a component, Fig. 4b the screw of the Fig. 2 in a state fully incorporated into the component.

[0015] The invention relates to a method for inserting at least one screw into at least one component. This can be done, for example, to connect two or more components together.

[0016] In the method according to the invention, the at least one component into which the at least one screw is to be inserted, as well as the at least one screw to be inserted into the at least one component, are first provided.

[0017] Furthermore, a viscous sealant is provided.

[0018] Before inserting each screw into the at least one component, at least one screw head of each screw is completely immersed in the provided sealant and thus coated with it. A section of the screw shank immediately adjacent to the screw head can also be immersed in the viscous sealant.

[0019] The screw is then inserted into the at least one component while the sealant is still in a paste-like state and has not yet hardened. During insertion, the sealant is at least partially squeezed out of a gap between the screw head and the component, or between the screw head and an intermediate body located between the screw head and the component. This seals the area around the screw head, particularly via the sealant squeezed out of the gap.

[0020] Further details of the invention are described below with reference to the figures. To ensure a simple presentation of the invention, it will now be described with reference to the figures in such a way that the screw shown is inserted into the component shown.

[0021] Fig. Figure 1 shows a container 10 in which a viscous sealant 11 is held. Figure 2 further shows Fig. 1 a screw 12, which is fully immersed in the viscous sealant 11 provided in the reservoir 10 to wet the screw head 13 of the screw 12. According to Fig. 1 also the section of the screw shaft 14 of the screw 12 immediately adjacent to the screw head 13 into the viscous sealing compound 11.

[0022] Fig. Figure 2 shows the screw 12 after it has been pulled out of the sealing compound 11 provided in the reservoir 10, wherein Fig. Figure 2 shows that the screw 12 is attached to those sections with which it engages in the viscous sealant 11 in Fig. 1 was immersed and is completely wetted with the viscous sealant 11.

[0023] Fig. 3a and Fig. Figure 3b shows the subsequent insertion of screw 12 of the Fig. 1 into the provided component 15. As already explained, the screw 12 is inserted into the component 15 in a state of the sealant 11 in which the sealant 11, which at least partially wets the screw 12, is pasty and therefore not yet fully hardened.

[0024] This involves Fig. 3a, Fig. 3b The sealant 11 is squeezed out of a gap 16 between the screw head 13 and the component 15, on which the screw head 13 comes into direct contact after the screw 12 has been fully inserted into the component 15. An area around the screw head 13 can thus be reliably sealed with the sealant 11.

[0025] Fig. 4a and Fig. Figure 4b shows a further development of the invention in which an intermediate body 17 is arranged between the screw 12 and the component 15.

[0026] This intermediate body 17 can in particular be a film which is glued onto the component 15, on which the screw head 13 indirectly comes into contact via the film, wherein the screw 12 is then subsequently inserted into the component 15, onto which the intermediate body 17 designed as a film has been glued.

[0027] Alternatively, the intermediate body 17 can also be designed as a washer, which is threaded onto the screw shaft 14 in particular before the screw 12 is inserted into the component 15, in order to then subsequently insert the screw 12 with the intermediate body 17 threaded onto the screw shaft 14 into the component 15 and thereby arrange the intermediate body 17 designed as a washer between the component 15 and the screw shaft 13.

[0028] The washer can also be placed loosely on component 15 in order to subsequently insert the screw 12 into component 15 with the washer positioned between component 15 and screw head 13.

[0029] Regardless of whether the intermediate body 17 is designed as a film or a washer, when the screw 12 is inserted into the component 15, the sealant 11 is at least partially, preferably completely, squeezed out of the gap 18 between the screw head 13 and the intermediate body 17 in order to reliably seal the area around the screw head 13. The sealant 11 completely covers those sections of the intermediate body 17 that protrude beyond the screw head 13.

[0030] The sealing compound 11 is in particular a wax or a wax-like sealing compound.

[0031] An MS polymer or a silane-modified polymer based on polyether can also be used as a sealant.

[0032] The invention allows for a reliable sealing of a screw 12 inserted into a component 15 with minimal use of sealant 11 and without the risk of air inclusions in the sealant 11.

[0033] If component 15 and screw 12 are made of different metallic materials, contact corrosion between component 15 and screw 12 can be avoided by using an intermediate body 17 made of an electrically non-conductive material.
