Definitions
- the invention relates to a method for fixing a component on a shaft wall of an elevator shaft of an elevator system, in particular a rail bracket for fixing the guide rail, and an elevator system with such a component fixed to the shaft wall.
- Conventional elevator systems include an elevator shaft and an elevator car.
- the elevator car can be moved in the opposite direction to a counterweight along the elevator shaft, which is arranged, for example, vertically.
- Both the elevator car and the counterweight are usually guided on two guide rails each. According to the direction in which they can be moved, these guide rails are fixed along the elevator shaft to a shaft wall of the elevator shaft. In order to anchor this guide rail on the shaft wall, rail brackets are fixed directly to the shaft wall.
- WO 2018/145984 describes a method for fixing such a rail bracket on a shaft wall of an elevator shaft.
- the guide rails are fixed to the shaft wall by means of the rail bracket.
- the rail bracket essentially consists of a rail bracket lower part and a rail bracket upper part, the rail bracket lower part being glued to the shaft wall.
- Anchors or screws are used, for example, to prefix the lower part of the rail bracket to the shaft wall in order to prevent slipping during the hardening of an adhesive layer between the shaft wall and the lower rail bracket part.
- the disadvantage here is that such a Vorfixie tion causes noise and dust by drilling holes in the shaft wall.
- This object is achieved by a method for fixing a component on a shaft wall of an elevator system, in particular a rail bracket to be fixed on the shaft wall, which rail bracket is suitable for fixing a guide rail within the elevator system, the component being a contact surface for flat fixing of the component to the manhole wall, the process includes the following process steps:
- the object is also achieved by means of an elevator system with a shaft wall and a component fixed to the shaft wall, which component is designed in particular as a rail bracket for fixing a guide rail of the elevator system, the component forming a contact surface for flat fixing of the component to the shaft wall and the Contact surface has two parts, wherein in a fi xed state of the component on the shaft wall between the contact surface and egg nem fixing area of the shaft wall in the first part of the contact surface a self-adhesive element and an adhesive layer is arranged in the second part of the contact surface.
- a component for fixing to a shaft wall of an elevator system, the component forming a contact surface for flat fixing of the component to the shaft wall and the contact surface forming a first part for applying a pre-fixing to a shaft wall suitable self-adhesive element and a second part for applying an adhesive, wherein the contact surface in its second part has at least one through-hole for applying the adhesive and / or for visual inspection of a space between the contact surface and the fixing area of the shaft wall.
- the fixing area corresponds to the area of the shaft wall, which is intended to receive the contact surface of the component directly by the method according to the invention for fixing.
- the contact surface of the component is divided into two main parts.
- the first part of the contact surface is provided with a self-adhesive element for pre-fixing.
- this can mean that the manhole wall to be attached component is previously provided with the self-adhesive element and accordingly has the self-adhesive element.
- the fixing area can be provided with the self-adhesive element beforehand in such a way that when the component is attached to the shaft wall for pre-fixing, the self-adhesive element is arranged on the first part of the contact surface and is accordingly not previously part of the component, in particular the rail bracket.
- Such a self-adhesive element can be gebil det, for example, by a material layer, which material layer is adhesive or adhesive on both sides to the shaft wall or to the first part of the contact surface of the component to be fixed.
- a material layer which material layer is adhesive or adhesive on both sides to the shaft wall or to the first part of the contact surface of the component to be fixed.
- double-sided adhesive tapes of various strengths or thicknesses.
- the second part is provided with an adhesive layer intended for curing.
- an adhesive layer intended for curing.
- the self-adhesive element and / or the adhesive forming the adhesive layer can be selected in such a way that vibrations of the component, which vibrations are caused, for example, by the operation of the elevator system, are not transmitted to the shaft wall or are transmitted to a greatly reduced extent. In other words, this means that the self-adhesive element or the adhesive is or has a vibration-isolating effect.
- a further development of the method comprises the following additional method step: applying the adhesive layer after the component has been pre-fixed on the shaft wall. Accordingly, the adhesive layer is applied after the component has been pre-fixed on the shaft wall.
- the component is pre-fixed to the shaft wall by means of the self-adhesive element, without the adhesive layer intended for curing being affected when the component is attached to the contact surface of the Component or is arranged on the fixing area of the shaft wall.
- the adhesive layer immediately afterwards, the component is fixed to the manhole wall or fixed by hardening the adhesive layer.
- a contact surface or fixation area that is not provided with an adhesive layer that has yet to be cured until the component is attached to the manhole wall enables the adhesive layer not to cause the component to be fixed to the manhole wall to a reduced degree by exemplary flowing away.
- the adhesive can be applied to the second part of the contact surface through a through-hole in the component that penetrates the contact surface.
- the component has at least one through-hole penetrating the contact surface for applying the adhesive layer or for visual inspection of a space between the contact surface of the component and the fixing area of the shaft wall.
- the adhesive can be applied to the second part of the contact surface through the through-hole.
- the adhesive layer can be applied by means of an adhesive pump.
- an adhesive pump By means of such an adhesive pump, an advantageous application of the adhesive through the through hole on the second part of the contact surface is made possible.
- Such an adhesive pump can be designed in the form of an adhesive gun and also have a flexible hose which can be guided into the perforation in order to be able to introduce the adhesive into the space between the contact surface and the fixing area.
- the through hole can be designed, for example, as a filler neck or as a filler valve.
- the through-hole is therefore suitable, for example, for introducing the flexible hose in order to be able to fill the adhesive into the space between the contact surface and the fixing area of the shaft wall. Filling the space between the contact surface and the fixing area of the shaft wall requires a defined amount of adhesive.
- the adhesive pump can be provided with a metering element, in particular a scale, which makes it easier to maintain a predetermined amount of adhesive when filling the space between the contact surface and the fixing area.
- the self-adhesive element has a thickness of 0.5 to 10 mm, preferably 0.5 to 3 mm, extending perpendicularly to the shaft wall.
- Another aspect of the selection of the thickness of the self-adhesive element results from the viscosity properties of the adhesive to be filled between the contact surface of the component and the fixing area of the shaft wall. This applies in particular to the case already mentioned in which the adhesive is applied to the shaft wall after the component has been pre-fixed. According to the predetermined distance, the adhesive can flow between the shaft wall and the contact surface.
- the first part of the contact surface is formed in an edge region of the contact surface or the self-adhesive element is applied in an edge region of the contact surface.
- the second part of the contact surface is preferably arranged within the first part of the contact surface.
- the self-adhesive element has at least one interruption in the edge area. Such interruptions make it possible for the air present between the contact surface of the component and the fixing area of the shaft wall to be displaced by the introduced adhesive when the adhesive layer is applied after the component has been pre-fixed on the shaft wall.
- the self-adhesive element can alternatively or additionally be made porous.
- such an interruption is maximally removed from the through hole for applying the adhesive.
- the interruption can accordingly be arranged in the corner of the first part of the contact surface that is most distant from this through-hole. If the adhesive flows through this interruption when the adhesive is applied to the second part of the contact surface, the person applying the adhesive can see that the space between the contact surface and the fixing area is filled with adhesive.
