Description

Fastening system, rail system, and mounting method for mounting a console of an elevator equipment rail system to a wall The present invention relates to a fastening system having two fastening elements for mounting a bracket of an elevator rail system to a wall, a rail system for an elevator, and a method for mounting a bracket of an elevator rail system to a wall. A bracket is part of the substructure for the rail system of an elevator facility. A bracket is also often referred to as a console. Multiple brackets can be arranged along the range direction of the rail system. The brackets are fastened to walls, for example, to the elevator shaft. To ensure the rail system is configured as straight as possible, the brackets are aligned along multiple axes during assembly. FR 2 996 216 shows the connection of a wall-mounted elevator guide. Alignment can be achieved, for example, by relative movement of elements screwed together. Movement can be enabled by at least one elongated hole that is aligned transversely to an axis so as to be aligned within at least one of the elements. For example, the relative position of the aligned elements can be fixed by using a dowel pin inserted through two elements. FIG. 1 is a three-dimensional drawing of a bracket for a rail system according to one embodiment. FIG. 2 illustrates a cross-sectional view of a fastening system according to one embodiment. FIG. 3 is a three-dimensional drawing of a fastening system during alignment according to one embodiment. FIG. 4 illustrates an aligned bracket for a rail system according to one embodiment. FIG. 5 illustrates a cross-sectional view of an aligned fastening system according to one embodiment. The drawings are merely schematic and not to scale. Similar drawing symbols indicate similar or equivalent features in various drawings. FIG. 1 is a three-dimensional drawing of a bracket (100) for a rail system (102) according to one embodiment. The bracket (100) is shown in an unmounted state. The bracket (100) is a crossbeam of the rail system (102) of an elevator facility. The bracket (100) is made of sheet metal. For example, the bracket (100) is designed as a stamped and bent section. The sheet metal of the bracket is, for example, 5 millimeters thick. The bracket (100) is substantially U-shaped or C-shaped to increase bending resistance. As a result of the profile, the bracket has a bottom surface and two side surfaces bent in the same direction from the bottom surface. The side surfaces are lower in height at the opposing end regions than at the center, that is, they are rounded or arched. The bracket (100) has two openings (104) in the end regions. The openings (104) are circular here and have a diameter of 100 millimeters. The openings (104) are arranged on the bottom surface of the bracket (100). The openings (104) are positioned in the center between the side surfaces. One of the side surfaces has a wide surface at each of the end regions, and the tabs are directed away from the bracket. Each of the tabs has an elongated hole that is aligned horizontally with the main size direction of the bracket (100). In one embodiment, each of the side surfaces near the end regions has an alignment notch (106). Each of the alignment notches (106) in the end regions is positioned on a common line perpendicular to the main size direction. The alignment notch (106) is designed here as a U-shaped groove at the edge of the side surface. The alignment notch (106) may also be designed as a protrusion across the edge of the side surfaces. FIG. 2 illustrates a cross-sectional view of a mounting fastening system (200) according to one embodiment. The fastening system (200) comprises two fastening elements (201) according to one aspect of the present invention. The fastening elements (201) are positioned on opposite sides of the bottom surface of a bracket (100) that substantially corresponds to the drawing of FIG. 1. Each of the fastening elements (201) has a receiving sleeve (204) for an anchor bolt (206) and a clamping plate (202) having a through hole (203). Each of the receiving sleeves (204) has a through opening (208) for an anchor bolt (206). The through openings (208) have a diameter slightly larger than the external thread (210) of the anchor bolt (206). A ball joint (212) is formed between the receiving sleeve (204) and the associated clamping plate (202). The anchor bolt (206) is designed here as a heavy-load anchor and has a clamping device (214) at one end. The end is placed in a hole (not shown) in a wall (not shown) and anchored to the wall using the clamping device (214). Then, the opposite end of the anchor bolt (206) protrudes from the wall. A first nut (216) is screwed onto an external thread (210), and a first fastening element (201) having a receiving sleeve (204) is pushed onto the anchor bolt (206) until the receiving sleeve (204) comes into contact with the first nut (216). The anchor bolt (206) is then guided through an openin
