The wall has a first concrete region that is reinforced with reinforcements and a second concrete region that is not reinforced. The second region covers the first region and has a surface that is exposed to the surroundings. The securing assembly has an elongated profile of C-shaped cross-section embedded solely into the second region and oriented in the vertical direction of the wall. Since tensile forces acting on a guide rail in an elevator shaft are very low, it is acceptable to secure the guide rail to the profile that is cast into the second region covering the reinforcement. The profile is anchor element-free and can be arranged in the wall vertically whereby guide rail holding consoles can be secured to the profile at any height. ## Claims ### Claim 1 A wall securing assembly for securing an elevator component to an elevator shaft wall in an elevator shaft, the wall securing assembly comprising: a first concrete region of the elevator shaft wall that is strengthened by reinforcements; a second concrete region of the elevator shaft wall that is not strengthened by reinforcements, covers the first concrete region and includes a surface that is exposed to surroundings in the elevator shaft; an elongated profile that is C-shaped in cross-section; and wherein the profile is embedded solely into the second concrete region and is oriented in a main extension direction of the elevator shaft, wherein the C-shaped profile extends vertically in the elevator shaft wall over substantially an entire height of the elevator shaft. ### Claim 2 (depends on 1) The wall securing assembly according to claim 1 wherein the elevator component is a guide rail secured to the C-shaped profile. ### Claim 3 (depends on 1) The wall securing assembly according to claim 1 wherein the C-shaped profile does not include any rigid anchor elements that protrude in a direction away from a rear surface of the C-shaped profile. ### Claim 4 (depends on 1) The wall securing assembly according to claim 1 wherein the C-shaped profile is received in the second concrete region in an interlockingly undercut manner. ### Claim 5 (depends on 1) The wall securing assembly according to claim 1 wherein at least one flank of the C-shaped profile is oriented towards the exposed surface of the second concrete region and is arranged inclined relative to the exposed surface. ### Claim 6 (depends on 1) The wall securing assembly according to claim 1 wherein the C-shaped profile has a depth, measured in a direction orthogonal to the exposed surface of the second concrete region, not exceeding 30 mm. ### Claim 7 (depends on 1) The wall securing assembly according to claim 1 wherein the C-shaped profile is formed as a sheet metal profile. ### Claim 8 (depends on 1) The wall securing assembly according to claim 1 wherein the C-shaped profile is formed as a plastics profile. ### Claim 9 (depends on 1) The wall securing assembly according to claim 1 wherein a front portion of the C-shaped profile adjoins the exposed surface of the second concrete region, and wherein an opposing rear portion of the C-shaped profile adjoins at least one of the reinforcements in the first concrete region. ### Claim 10 (depends on 1) The wall securing assembly according to claim 1 wherein at least one textile region is attached to the C-shaped profile, the textile region consisting of a plurality of flexible metal wires that are flexural prior to being embedded in the second concrete region, the flexible metal wires extending from the C-shaped profile at least one of individually, as a bundle and as a web. ### Claim 11 (depends on 1) The wall securing assembly according to claim 1 including a holding console for holding a guide rail as the elevator component, the holding console being secured to the wall securing assembly by a securing element that engages in the C-shaped profile. ### Claim 12 (depends on 11) The wall securing assembly according to claim 11 wherein the securing element includes a securing bolt having one end adapted to engage the holding console and an opposing end adapted to be screwed into a securing plate received in the C-shaped profile. ### Claim 13 (depends on 12) The wall securing assembly according to claim 12 wherein the securing plate is adapted to be interlockingly received in the C-shaped profile. ### Claim 14 (depends on 1) A method for securing elevator components to an elevator shaft wall in an elevator shaft using the wall securing assembly according to claim 1, the method comprising the steps of: attaching at least one holding console to the C-shaped profile at a selected height in the elevator shaft, the at least holding console adapted to hold a guide rail as one of the elevator components. ### Claim 15 (depends on 14) The method according to claim 14 including securing the at least one holding console with a securing element that engages in the C-shaped profile. ### Claim 16 A wall of an elevator shaft including a wall securing assembly comprising: a first concrete region of the wall that is strengthened by reinforcements; a second concrete region of the wall that is not strengthened by reinforcements, covers the first concrete region and includes a surface that is exposed to surroundings in the elevator shaft; and an elongated profile that is C-shaped in cross-section and is embedded solely into the second concrete region, the C-shaped profile being oriented in a main extension direction of the elevator shaft and extending vertically in the wall over substantially an entire height of the elevator shaft, the C-shaped profile adapted for securing an elevator component to the wall. ### Claim 17 (depends on 16) The wall according to claim 16 including a holding console for holding an elevator guide rail as the elevator component secured to the wall securing assembly by engaging the C-shaped profile.
